This is a professional business proposal for small size 400kg/h complete biomass pellet production line for wood mushroom-stick crop stalk peanut shells,which is made by Richi Machinery in May 2019.
The sustainable development of society requires continuous energy supply and environmental protection. The industrial exploitation and large-scale use of petrochemical fuels such as petroleum, coal and natural gas have not only caused environmental pollution and the greenhouse effect, but their non-renewability has gradually reduced the amount of resources, resulting in excessively high prices and unable to be used in large quantities in the vast rural areas. In addition, the direct combustion of fossil fuels and agricultural and forestry wastes is one of the main sources of urban PM2.5, especially the direct combustion of untreated straw in the harvest season and the emissions of coal for heating in winter.
Biomass pellets are mainly used to replace traditional petrochemical energy sources (oil, coal, natural gas), greatly reduce the value of PM2.5 in the air, and reduce haze weather. The production of this product can make the rational use of agricultural and forestry wastes and reduce direct combustion emissions. Air pollution is conducive to improving the environment. It is an ideal environmental treatment technology that follows the three principles of innocuous, resource-based, and reduced biomass raw materials. The environmental and social benefits are very significant.
The client invested 130,000 USD (approximately RMB 800,000) to rent an idle local plant (plants and other supporting facilities have been completed) to build a small scale 400kg/h biomass pellet fuel production line for wood mushroom-stick crop stalk waste peanut shell. After the 400 kg per hour biomass wood pellet line project is completed, it will produce 1,000 tons of biomass pellet fuel per year.

The construction of this project complies with the relevant national laws, regulations and policies, so the construction of this project complies with the requirements of the national industrial policy.
8. Analysis of the rationality of planning and site selection for 400kg per hour low cost small wood pellet production line
(1) Planning compliance
The project rents the idle flue-cured tobacco base plant in Xianglu Mountain, Nenzhai Village, Tonggu Town, Jinping County, Guizhou Province, which belongs to a rural area and is not within the scope of the overall urban planning of Jinping County. With the rapid economic development of Jinping County, in response to the national rural revitalization plan and speeding up the construction of new rural areas, this project can provide high-quality fuel for local construction and provide employment for surrounding residents. Therefore, the construction of this project meets the planning requirements. Therefore, the project planning is basically reasonable.
(2) Analysis on the rationality of site selection
The project rents the idle flue-cured tobacco base factory building in Xianglu Mountain, Nenzhai Village, Tonggu Town, Jinping County, Guizhou Province. The project occupies a land area that does not involve nature reserves, scenic spots, and concentrated drinking water source protection areas for more than 1,000 people, and other prohibited development zones. It is not in Guizhou Province. In the ecological protection red line area, the project construction meets the requirements of the "Notice of the Provincial People's Government on Issuing the Ecological Protection Red Line of Guizhou Province" (Qianfu Fa  No. 16).
In addition, the small capacity 400kg per hour good selling new design pellets machine line project construction does not occupy basic farmland or forest land, and no national rare wild animals and plants grow in the area. The site selection of the project has a good geographical advantage. The water supply, power supply and communication facilities of the project site are complete, and the transportation is convenient. It meets the requirements of relevant land use planning. At the same time, the pollution generated during the project operation period will have little impact on the surrounding environment after measures are taken for treatment. In summary, the site selection of the project is basically reasonable.
(3) Analysis of rationality of layout
The best price small capacity 400kg per hour wood pellet mill plant project design fully considers the layout of the facilities and the status quo of the factory building, and strives to close the facilities. Generally, the functional divisions such as the crushing area, the drying area and the finished product area are clear, the layout is reasonable, the connection is convenient, the entire production process is smooth, and the production workshop is a semi-enclosed steel structure plant.
The 400kg per hour low cost straw wood pellet production line project will set the factory entrance and exit on the north side, connecting roads to facilitate the transportation of raw materials and products; the raw material area is on the southwest side of the plant; the project office area is located on the northwest side, and the crushing area and drying area are located on the north side of the plant, which is convenient for managing production; The dominant wind direction in the area is southeast wind, and the exhaust pipe is located in the northeast corner of the plant. The office area is not in the raw material storage yard or the downwind area of the production workshop. After the exhaust gas has been treated to meet the standards, the impact on the office and living area is small, and the overall layout is basically reasonable.
9. Brief description of 400kg/h easy to handle biomass wood pellet production plant process flow
(1) This easy to handle 400kg/h stable performance biomass wood pellet production line project purchases wood scraps from wood processing plants, waste mushroom sticks from the mushroom stick factory, and crop waste collected from farmland (paddy stalks, peanut shells, walnut shells, etc.) as raw materials.
(2) The raw materials are firstly sliced, screened, and crushed by a biomass materials pulverizer, until the material size meets the requirements of the biomass wood crops granulator.
(3) Due to the high moisture content in the raw materials, the feed conditions of the biomass pellet making machine cannot be met, and the materials need to be dried. The pulverized raw materials are then burned with biomass fuel through a dryer, and the biomass pellet fuel enters the high-temperature combustion chamber through the automatic feeding system, where high-temperature combustion occurs rapidly in the high-temperature combustion chamber to generate high temperature.
(4) After drying, the material is conveyed to the biomass wood stalk pellet press machine by the conveyor belt, and is fed by the leucorrhea feeding equipment of the ring die biomass wood pellet making machine. The biomass raw material is sent to the feeding chamber of the wood pellet maker machine, in the distributor and scraper. Under the combined action of the dies, it is evenly spread on the ring die, and then the material is squeezed into the die hole. The material undergoes forming and shape retention processes in the die hole.
Due to the increase in pressure in the ring die biomass wood pelletizier machine, the particles themselves deform and flow plastically, and generate a lot of heat under the action of friction, which causes the lignin contained in the raw materials to soften and increase the adhesion force. The combined action of cellulose makes the biomass gradually shape, and after a certain period of time, it is extruded in a cylindrical shape. The rotating cutter cuts the material to form a cylindrical shape and sends it out through the discharge port. This 400kg/h simple design biomass wood agricultural waste pellet line project does not add binder during the pelletizing process.
(5) After extrusion, the pellets are packaged after natural cooling. The packaging stage mainly produces packaging waste and substandard products.
(6) The packaged product can be sold outside.
10. Summary of environmental impact and prevention measures during operation
(1) Conclusion of atmospheric environmental impact analysis
According to the analysis of the process flow of the small capacity 400kg per hour wood pellet production line project, the waste gas during the operation period is mainly the dust generated in the crushing process, the dust generated in the granulation molding process and the waste gas generated by the dryer in the drying process. In addition, a small amount of unorganized dust is generated in the processes of raw material loading and unloading, storage, and transfer.
①Crushing dust: The dust generated by the grinder is discharged after being treated with a Shakelong dust collector + a bag filter, and its dust emission meets the limits of the secondary standard in Table 2 of the "Comprehensive Emission Standard of Air Pollutants" (GB16297-1996) Claim. The impact on the atmospheric environment is small.
②Exhaust gas from drying kiln: After the exhaust gas (smoke, SO2, NOx) is treated by the water film dust collector, the emission concentration of soot and SO2 meets the requirements of the secondary standard in the "Industrial Furnace Air Pollutant Emission Standard" (GB9078-1996) , NOx emission concentration meets the second-level standard in "Comprehensive Emission Standard of Air Pollutants" (GB16297-1996). It is then led to a 15m high exhaust pipe for exhaust.
③Dust in the production workshop: In view of the unorganized discharge of dust in the workshop, the ventilation of the workshop is strengthened so that the workshop can reach the standard of unorganized emission limit in the Comprehensive Emission Standard of Air Pollutants (GB16297-1996).
④Dust in the granulation and molding process: the dust generated by the granulation and molding machine is discharged unorganized after being treated with a bag filter, and its dust emission meets the limit requirements of the secondary standard in Table 2 of the "Comprehensive Emission Standard of Air Pollutants" (GB16297-1996) . Less impact on the atmospheric environment.
(2) Conclusions of acoustic environmental impact analysis
The process of this 400kg/h wood mushroom-stick crop straw peanut shell waste pellet production project is simple. The main noise source comes from the mechanical noise generated by the original crusher, dryer, extrusion molding machine, conveyor belt, etc. The noise source strength is generally between 70~90dB(A), and each production equipment is installed. In the production workshop, each equipment is equipped with shock-absorbing cushions underneath, and the noise in the workshop is controlled by means of building sound insulation. After passing the above measures, the sound source intensity of this project is ≤80dB(A).
The noise prediction results show that the contribution value of the noise source to the plant boundary is between 36.47-44.70dB (A). Therefore, the noise at the project plant boundary can reach the Class 2 standard of "Environmental Noise Emission Standard for Industrial Enterprise Plant Boundary" (GB12348-2008). Environmental assessment requirements: Strictly implement sound source noise reduction measures and sound insulation treatment measures in production workshops and raw material warehouses to ensure that the environmental quality of the project's factory boundary meets the standards.
In addition, high-noise equipment should be reasonably arranged and the operation time of high-noise equipment should be arranged.
(3) Analysis conclusion of solid waste impact
The solid waste generated by this 400kg per hour best price complete wood pellet production line project mainly includes the domestic garbage of employees, dust collection by bag dust removal, furnace ash, waste packaging bags generated in the packaging process, and waste engine oil. After the household garbage is collected, it will be cleared and transported to the place designated by the environmental sanitation department by special personnel for centralized disposal; the dust collected by bag dust is reused as raw materials for production, and is not discharged; waste packaging bags are collected and recycled by the original manufacturer, but are not discharged; Dust collector replacement bag: The dust collector is regularly replaced when the bag is replaced by the manufacturer for recycling.
The ash is collected and used as fertilizer for the land; a certain amount of waste engine oil will be generated from the mechanical repair of the plant equipment. The environmental assessment requires the establishment of a temporary storage room for hazardous waste (anti-seepage treatment is required), and the waste engine oil that can be used is used for the lubrication of machinery and equipment. Those that cannot be used are periodically handed over to a unit qualified for hazardous waste disposal for disposal.
The solid waste of this project has a clear destination and will not cause secondary pollution. In summary, the project construction has certain impacts on the surrounding ecological environment, water environment, air environment, and acoustic environment. However, overall, the impact of the project on the environment is relatively small, and the impact on the environment after the adoption of environmental protection measures can be significant. Control at an acceptable level. From the perspective of environmental protection, the construction of this project is feasible as long as the pollution prevention and control measures proposed in this report form are implemented strictly.
11. Environmental protection investment and total control
