8. General layout
This large 28 ton wood rice husk pellet production line for biomass pellets project is located in Jingcheng Rice Industry, east of Jiu San Road, Huaqiao Town, Wuhu County, with a total area of 7,500 square meters.
According to the nature of the project's production and construction scale, the general layout will be arranged in accordance with the natural conditions and current situation of the site. Under the premise of satisfying industrial production land, the land use needs of material transportation, pipeline laying, environmental protection, safety and health, and fire protection have been considered in overall planning. Strive for a reasonable layout of the general map and short and smooth transportation routes. The building structures are coordinated and tidy in appearance, and the passage width is moderate, creating conditions for natural ventilation, lighting, drainage, and sanitation.
The 28t/h China complete biomass wood pellet production line project is arranged in a plane according to the production process, and the material transfer during production is smooth, which is conducive to improving production efficiency. It can be seen from the layout that the flow of people, vehicles, and freight are clear. The layout of this project is conducive to the production collaboration of various departments during the production and operation of the project and improves production efficiency. Generally speaking, the layout of this project is relatively reasonable.
9. Reasonable analysis of site selection
The local government document stated: "New projects enter the development zone. For projects under construction within 1 km of the bank of the Yangtze River and main tributaries, all those that should be relocated shall be moved to the compliant development zone in accordance with laws and regulations. The bank of the Yangtze River is 5 kilometers. All the heavy chemical projects under construction within the scope that are difficult to rectify and meet the standards and must be relocated must be moved into compliance development zones in accordance with laws and regulations.
Within 15 kilometers of the shoreline of the Yangtze River, all new industrial projects will in principle enter the development zone, of which chemical projects enter the chemical industry. The development zone or the development zone where the main industry is the chemical industry". This project belongs to the C2542 biomass compact fuel processing. It is located in the Jingcheng rice industry east of Jiu San Road, Huaqiao Town, Wuhu County. It is 34km away from the Yangtze River and 11km from the Qingyi River, the main tributary of the Yangtze River. It is in line with Wanfa  No. 21 Relevant requirements in the document. In summary, the site selection of this project is reasonable and meets the planning requirements.
Wood waste-chipping-crushing-drying-(add rice husk here) pelleting-finished product
(1) Chipping: Use a new technology agricultural wood chips crusher to perform primary processing of raw wood chips, and chip the raw materials on the original basis to meet the subsequent processing needs;
(2) Crushing: The particle size of the raw material after chipping is still large, which is not easy to granulate. Use a wood pulverizing milling machine to further crush it to make it easier to process;
(3) Drying: The moisture content of the raw wood chips is about 40%, which is not conducive to subsequent processing. Use a dryer to dry, and the drying itself only produces a small amount of water vapor.
(4) Pelleting: Use a belt conveyor to send the materials to the new design high quality biomass wood pellet making machine to be compacted and granulated to form finished pellets. Rice husk is directly made into rice husk biomass pellet fuel through this process.

12. Environmental impact assessment
(1) Exhaust gas
Crushing, briquetting and granulating dust is equipped with air collecting hood + bag filter + 15m high exhaust cylinder; the dryer is equipped with cyclone dust collector + bag filter + 15m high exhaust cylinder. The dust emission in the crushing and granulation section shall comply with the particulate matter emission standard in Table 2 of the New Pollution Sources in the Comprehensive Emission Standard of Air Pollutants (GB16297-1996), and the fugitive emission dust shall comply with the fugitive emission monitoring concentration limit in the standard.
The exhaust gas of the dryer meets the requirements of the Ministry of Ecology and Environment's "Notice on Issuing the "Industrial Furnace Air Pollution Comprehensive Treatment Plan"" (Huan Qiqi  No. 56] for industrial furnaces that have not yet formulated industry emission standards. Key points Regional emission limits for particulate matter, sulfur dioxide, and nitrogen oxides.
After being treated by integrated sewage treatment facilities, domestic sewage will be discharged into the surrounding ditches after reaching the first-level standard in the "Integrated Wastewater Discharge Standard" (GB8978-1996).
The noise source intensity of this big capacity wood and rice husk pellet processing plant project is mainly the noise generated by the operation of production equipment, and the noise source intensity is 60-80dB(A). For high-noise equipment, noise reduction measures such as basic damping and car separation sound are taken. It is predicted that with the attenuation of the distance, the noise emission at the plant boundary of the project can meet the requirements of Class 2 standard in the "Environmental Noise Emission Standard at Industrial Enterprise Plant Boundary" (GB12348-2008), and has little impact on the surrounding acoustic environment.
(4) Solid waste
The dust collected by the dust collector is reused for production; the household garbage is collected and entrusted to the sanitation department for centralized treatment.
