7. Layout principles

(1) According to the production requirements, considering the professional requirements of craftsmanship, construction, fire protection, etc., reasonably arrange the locations of the production workshops, warehouses, auxiliary workshops and markets, and strictly partition.

(2) The roads in the factory area should be convenient for the transportation and loading and unloading of products, and the main road should be suitable for fire-resistant vehicles.

(3) The power supply is as close as possible to the load center to reduce the loss of power and energy.

(4) According to the environmental protection requirements and the production characteristics of the enterprise, the plant area is reasonably arranged with green belts to achieve the purpose of beautifying the environment and improving the environment.

8. Design plan for 20 tons per hour agriculture waste biomass wood pellet line

(1) General layout plan

The land for this project is basically a north-south rectangle, with the gate set on the south. In order to show the corporate image and culture, the entry is the office building; according to the process flow and convenient logistics and transportation, the raw material warehouse, main workshop and finished products warehouse are unknown from south to north; logistics circular roads are arranged on the east and west sides, separated from the pedestrian flow roads. All functional areas should be properly greened to beautify the plant environment and improve the quality of life.

layout of Turnkey fully automatic 20t/h forest waste and agricultural waste pellet production plant project

(2) Plant traffic and environment

The transportation planning in the factory area is based on production needs, local transportation status and development planning, combined with natural conditions and requirements, to meet the requirements of production, transportation, installation, maintenance, fire protection and environmental sanitation, connecting with roads outside the factory, and making overall arrangements to facilitate operation and management. The people-vehicle diversion system is adopted to form circular lanes around the buildings in the factory area, which can easily reach various functional areas.

Because of the forward-looking corporate planning, the existing factory has wide roads, shaded trees, and beautiful environment. It is a typical garden-style modern enterprise. It not only beautifies the working environment, but also optimizes the investment environment and builds corporate culture , It has played a positive role in enhancing the competitiveness of enterprises. Taking into account the fire protection requirements, circular lanes are set up around the production workshop, stacking, warehouse, etc.

The greening of the plant area adopts a vertical multi-level method. Low trees and shrubs are planted along the fence, trees, flowers, lawns and other plants are planted along the road and in the open space. A small number of tall trees are dotted around the workshop, so that people will be surrounded by green bushes and flowers after entering the factory.

9. Transportation

(1) Transportation outside the factory

The main transportation method outside the factory is road transportation, and the transportation objects are raw materials and finished products. Straws, branches (roots, etc.), and wood chips are transported by agricultural vehicles. The products are packed in woven bags and transported by truck. The project is located in the Wanling Agricultural and Sideline Products Processing Park in Qiongzhong County. The main transportation route outside the park is the Haiyu Middle Line (G224), and the Haiyu Middle Line is connected to the Nawu Line (S307) to the south.

(2) Transportation within the factory

The transportation tools in the factory include cars, forklifts, battery flatbed trucks and trolleys. This type of vehicle is flexible, has a large or small load, has a small investment in road infrastructure, and is easy to use. The transportation of raw materials, auxiliary materials, finished products, etc. between warehouse and workshop, workshop and workshop, and various processes within the workshop according to the production route and technological process are all in-plant transportation. According to the turnover of materials, in-plant transportation can be divided into the following stages:

①Transport the raw materials to the factory;

②Transfer the raw materials into the warehouse or to the storage site;

③Transfer the materials from the warehouse or stacking site to the workshop;

④Send the products from the finished product warehouse to the factory.

10. Site selection principle

(1) The site of the 20t/h low investment high return wood agricultural and forestry waste pellet line plant should be located in a place with abundant raw materials and convenient transportation. The 20 tons per hour biomass waste pellet energy plant area should be close to the main traffic arteries, which can not only facilitate production and transportation, but also reduce costs and facilitate transportation and marketing.

(2) The topography of the plant site should be flat, the geology should be hard, the ground water level should be low, and the ventilation should be good.

(3) The surrounding environment of the factory area should avoid factories and residential areas that are inflammable and explosive, and emit toxic gases and harmful dust; there should be a relatively spacious temporary land around the factory area for the storage and drying of raw materials.

(4) The site selection should be based on local conditions to save land. It is necessary to make full use of wasteland or idle land and not occupy or occupy less farmland. Where conditions permit, use the original idle sites and workshops as much as possible to reduce investment.

(5) The plant site should not be too far away from the power supply line to reduce power supply system investment and power loss. There should also be corresponding water sources nearby to meet the water needs of production departments, life and fire fighting.

(6) The area of ​​the site should be suitable for the cargo transportation, safety and health requirements in the production process, and leave an appropriate amount of room for development.

11. Address selection

According to the above principles, the 20t/h agricultural and forestry waste pellet making line project site is located in Wanling Wanling Agricultural and Sideline Products Processing Park Town, Qiongzhong County, on the west side of 113.8m from the Haiyu Middle Line. The project location has the following advantages:

(1) The project is close to the middle line of Haiyu, which is conducive to the transportation of raw materials and products.

(2) The project land is planned as industrial land, and the project is close to Wushi Farm, and the electricity and water transmission around the project are reliably guaranteed.

(3) The site has flat terrain, hard geology, low groundwater level, and good ventilation. Avoid areas that may be flooded, landslides, and collapses.

(4) The surrounding environment of the site is open and there is no residential area.

(3) Complete 20t/h wood straw pellet mamufacturing process flow

The technological scheme adopted in this project is: raw material-screening-crushing-drying-cyclone separation-compression molding-cooling-packaging.

①Sieving and crushing of raw materials

The raw materials of the project are mainly woodland felled materials, woodland miscellaneous irrigated materials, etc. The raw materials of the project are collected, and large wood blocks and debris are removed by a drum screen, and then crushed by a shredder.


Biomass briquettes have strict requirements on the water content of the raw materials. After being crushed, the raw materials are sent to the drying system of the hot air oven for hot air drying after being crushed.

③Cyclone separation

After the raw materials are dried, the moisture will be removed by the cyclone separator during the conveying process. At the same time, the molded fuel is cooled and passed through a cyclone to separate the molded fuel and moisture.

④Granulation molding

Biomass fuel molding machine is the key equipment of the production line. This project uses MUZL1610M sawdust pelletizer. This equipment uses a single-motor V-belt transmission system with ideal transmission ratio, large driving torque and stable transmission; equipped with φ6mm— Ring molds with a variety of apertures and thicknesses between φ12mm can be selected by users according to different needs to obtain the best technical and economic benefits; advanced frequency conversion motors are used for feeding, with overload protection devices and magnetic plates Iron device; high output, low noise, convenient operation and maintenance.


The temperature of the discharged biomass fuel is as high as 80-98 degrees, the structure is relatively loose, and it is easy to be broken. It must pass through a countercurrent cooling system and be cooled to normal temperature before being put into storage.


After the project is cooled, the products are measured, packed in bags, and sent to the finished product warehouse.

12. Raw material supply

After the first phase of the 20t/h biomass pellet fuel project is completed and put into production, it will require 80,000 tons of raw materials each year, which is equivalent to 90,000 cubic meters of wood at 0.88 tons per cubic meter of wood dry weight. After the second phase of the project is completed and put into production, it will need to convert raw materials to 180,000 cubic meters of wood each year. These raw materials can be used wood cutting residues (branches, leaves), wood processing and production corner waste (including board, edge strips, truncated, shavings, sawdust, etc.), urban waste wood, etc. as raw materials. In addition, agricultural wastes such as straw, bagasse, banana stalks, miscanthus, etc. can also be used as raw materials.

Source of raw materials:

The wood raw materials required for the production of this project with a hourly output of 50,000 tons biomass pellets mainly come from wood logging residues and wood processing residues. According to the above analysis, it can collect 845,000 cubic meters of wood logging residues, 604,000 cubic meters of rubber renewal logging residues, 15 million cubic meters of corner waste after processing rubber sawn timber, and 331,000 tons of fruit tree pruning residues each year. Annually, 1.93 million cubic meters of logging residues and processing residues can be collected.

The biomass pellet fuel project with an hourly output of 20 tons only requires 90,000 cubic meters of wood raw materials, plus the demand for wood raw materials from the four fiberboard plants that have been put into production and under construction, and a total of 935,000 cubic meters of wood raw materials are consumed each year. The supply of wood raw materials across the island is greater than the demand of 935,000 cubic meters, which is 2.1 times the demand.

This does not include the forest resources of the Hongling Reservoir burial area, the 35,000 tons of miscellaneous irrigation and branch materials signed with Dayu Company, and the 8,000 tons of miscellaneous irrigation and branch materials signed with Daxing Fruit Development Company. The province's forest tending and thinning small-diameter timber, foreign timber that is difficult to sell in the market, urban waste timber, and customers through the establishment of raw material procurement (harvesting) purchase points across the island, exchange biomass pellet fuel for the living firewood of forest farmers in the mountains for processing Raw materials, collecting orange stalks, bagasse, banana stalks, miscanthus in agricultural wastes as raw materials for production, etc.

13. Project energy consumption

The main types of energy consumption of the project are electricity and water. The main energy consumption of the project is the electricity consumption of the project's production equipment and the energy consumption of the hot blast stove.

(1) Annual power consumption

The total installed capacity of the project is 1250.4kw, the production time of the project is 10 hours, and the number of production days is 300 days, the power consumption of the project is 3.751 million kwh.

(2) Biomass fuel

The hot blast stove of the project uses self-produced biomass fuel. The hot blast stove of this project uses 80kg biomass pellets per hour. The working time of the project is 10 hours and the working time is 300 days. The hot blast stove of the project uses 240t of fuel. The calorific value of biomass fuel of this project is 4300kcal/kg, and the calorific value of standard coal is 7000kcal/kg, so the conversion coefficient of biomass fuel is 0.6142 kgce/kg.

14. Environmental protection and comprehensive treatment measures

(1) Dust

Construction dust comes from the construction site. Regular water spraying is used to make clear regulations on the route of the vehicle. When building materials are stacked in the open air, they should be covered with tarpaulin. The processed dust during the operation period can reach the national standard by adopting cyclone dust collector to separate and collect dust.

(2) Wastewater

Construction wastewater comes mainly from construction sites and is treated in a temporary septic tank and then reused in the surrounding rubber forest; a small amount of domestic sewage in operation is treated in a septic tank and then reused for woodland irrigation.

(3) Combustion waste gas

The drying furnace uses wood chips and biomass particles as fuel to produce industrial waste gas. After the chimney is treated by the multi-tube cyclone dust removal method, it can meet the requirements of the "Industrial Furnace Air Pollutant Emission Standard" (GB9078-1996).

The pulverized dust is collected by a bag filter and discharged through the chimney of the drying furnace.

(4) Noise

Construction noise mainly comes from transportation vehicles, construction machinery and equipment. The work surface and the driving route of construction vehicles are well controlled. The noisy machinery and equipment are arranged far away from residential buildings. During construction, night construction should be avoided to disturb the residents. Noise pollution during operation comes from the production equipment. When installing large noisy equipment, take shock-absorbing measures, install sound-absorbing covers and shock-absorbing pads, and if necessary, adopt sound-absorbing and sound-proofing treatments in the building.

15. Project suggestion:

(1) In order to ensure product quality, it is recommended to purchase raw materials that have been stored for 3-6 months as raw materials for this project.

(2) The environmental protection device of this project must be designed, constructed and put into use at the same time as the main project.
