2500 Tons Per Month Large Capacity Wood Pellet Factory For Making Wood And Agricultural Waste Straw Pellets(12.5TPH)

Utilities

• Water supply and drainage

  This 12.5t/h wood pellet factory project uses the municipal water supply pipe network of Yankou Town. The drainage system of the wood pellet factory area shall be implemented with the rainwater and sewage diversion system.

  The wastewater in the 12.5tph large wood pellet factory area is mainly domestic sewage. After the domestic sewage is treated in the septic tank, it is regularly cleaned and used as agricultural fertilizer, and is not discharged outside.

• Powered

  The power supply of this 12.5tph large wood pellet factory project is connected to the municipal power supply system of Yankou Town, which can meet the electricity demand of the wood pellet factory project.

Wood pelletizing process design

Note: The raw material (sawdust, straw, etc.) storage sites of this 12.5t/h wood pellet factory project should be set up in the workshop and not stored in the open air; closed measures should be taken for the conveyor belts, feeding and blanking ports, etc., to increase the air volume of the air collecting hood and improve exhaust gas collection efficiency, strengthen equipment maintenance, keep dust removal equipment in good condition; strengthen workshop ventilation, and discharge unorganized dust up to the standard.

1. Crushing and pulverizing

   The main raw materials, straw and wood chips, are pulverized by wood crusher machines and straw crushers to make the particle size less than 5mm.

2. Drying

   For some waste wood scraps with high water content, it is necessary to dry the granules that have been pulverized as raw materials to make their moisture content meet the requirements for granulation (moisture content is less than 5%).

   The materials in this wood pellet factory project are dried. The wood dyer machine is usually equipped with a biomass hot blast stove or boiler, and the fuel is biomass pellets.

3. Conveying and feeding

   The raw materials are sucked into the feeding port of the wood pellet making machine through the feeding auger.

4. Pelletizing

   The raw materials are fed into the wood & straw pellet machines through the feeding auger, and the finished product is made by extrusion molding. The extrusion process is a physical process, no adhesive is added, and no chemical reaction occurs.

   Except for the connection of the feeding auger, the pelleting systems for straw wood machine is sealed at the place and the discharge port and outside.

5. Conveying and cooling

   The granulated biomass pellets are naturally cooled by conveying, so that the temperature can reach the conditions of packaging and storage, and finally conveyed to the finished product storage tank.

6. Packaging and warehousing

   After cooling in the storage tank, the products are packaged and put into the warehouse.

Material balance

Analysis of rationality

This wood biomass pellet mill factory project mainly reconstructs the crushing workshop, pelletizing workshop, raw material warehouse and finished product warehouse.

The entrance and exit of the wood pellet mill factory project are located on the west side of the factory area, the crushing workshop and molding workshop are located on the north side of the wood pellet factory area, and the office area is located on the south side of the wood pellet factory area.

Outside the gate of the wood pellet factory is a rural road, about 100 meters to the west to connect to the 020 county road, the transportation of products and raw materials in the factory is very convenient.

The overall production workshop of this wood pellet factory project is arranged from east to west according to the wood pellet production process flow, followed by crushing workshop (about 400㎡ area is set aside as a raw material stacking area in the workshop, and the daily storage of raw materials such as straw and wood chips is about 800 tons) , crushing workshop, granulation workshop and finished product stacking workshop.

The crushing workshop and pelletizing workshop are the main pollution sources of the wood pellet factory project. They are located on the north side of the wood pellet factory area. The north side of the wood pellet factory project site is surrounded by forests and farmland, which can be used to reduce dust and noise and reduce the impact on surrounding residents.

According to the noise prediction results, the noise at the biomass pellet production line project boundary can reach the emission standard. The overall layout of the wood pellet factory project is reasonable.

Analysis of rationality of planning and site selection

The location of the large wood pellet factory project site has convenient transportation, flat terrain and superior geographical location, which is conducive to the transportation of raw materials, auxiliary materials and finished products required for the production of the large wood pellet factory project.

Convenient communication, abundant energy supply, suitable for manufacturing activities. The large wood pellet factory project site is located in Yankou Town, Shou County, Huainan City, Anhui Province. The large wood pellet factory has been built by renting a rice seed farm.

The large wood pellet factory project will not add new land. The north and south sides of the large wood pellet factory project are farmland, and the east side is forest. The large wood pellet factory project is about 100m from 020 County Road, there are rural road connections between them, and the transportation is convenient.

There are no nature reserves, scenic spots, drinking water sources and other environmentally sensitive targets around the 100m site, and the natural environment conditions are good.

All pollutants of the large wood pellet factory project can be discharged up to the standard after treatment, with little impact on the surrounding environment. The large wood pellet factory project conforms to the general land use planning of Yankou Town, Shou County, and conforms to the local construction plan.
