6. Public Works of Straw Sawdust Rice Husk Pellet Production Line:

① Water supply and drainage

Water supply: The water for the project is provided by the local tap water pipe network, and the water consumption is 1m3/d (300m3/a).

Drainage: The wastewater of the project is mainly domestic sewage with a production volume of 0.8m3/d (240m3/a). After treatment in a septic tank, it is used as agricultural fertilizer and is not discharged.

② Power supply

The electricity used by the project is drawn from the power supply network of the park. The annual electricity consumption of the project is 1.5 million kWh, which can meet the electricity demand of the project.

③ Storage and transportation engineering

Set up a raw material/finished product warehouse with a construction area of 1200m2.

The transportation within the factory relies on manual handling or forklift, and the transportation outside the factory is commissioned by social vehicles.

7. Work System and Labor Quota

Work system: This project adopts a single-shift system, 8 hours per shift, 300 days of work per year, and 2400 hours per year.

Labor quota: 10 labor quotas for this project, including 3 administrative and management personnel.

8. Environmental Protection Investment in Straw Sawdust Rice Husk Pellet Production Line

The environmental protection investment of this project is 310,000 RMB, accounting for 3.1% of the total investment of 10 million RMB. See Table 6 for a list of environmental investment and facility budget estimates for this project.

9. Process Flow of Straw Rice Husk Pellet Production Line

(1) Screening: The raw materials used in this project are determined according to the order requirements and the market raw materials. The main types are sawdust, rice husk, rapeseed stalk, and corn stalk. Among them, rice husk, rapeseed stalk, and corn stalk are all crushed raw materials. . After the raw materials enter the factory, they enter the screening machine for screening to remove impurities, such as some large pieces of straw and bark. The main pollutants in this process are the filtered impurities and equipment noise.

(2) Drying: Sawdust mainly comes from wood processing plants. During the wood processing process, water will be carried out. Therefore, the moisture content of the produced sawdust is relatively high, about 60%-80%, and it cannot be directly fed into the pelletizer for granulation. , It needs to be dried first. After screening, it enters the horizontal dryer through a hoist. A steam boiler provides the heat source. After drying, the moisture drops to about 15%. The pollutants produced in this process are mainly drying waste gas and dust.

(3) Granulation: The dried sawdust or the sieved rice husk, rapeseed stalk, corn stalk, etc. are sent to the raw material warehouse by the conveyor belt, and then conveyed by the auger into the granulator for granulation. The pellets are made into finished products by extrusion molding. The extrusion process is a physical process, no adhesive is added, no chemical reaction occurs, and a small amount of dust is generated in this process.

(4) Cooling: The prepared straw particles enter the packaging machine through a hoist, and cool naturally during the hoisting process.

(5) Packaging: This project uses a fully automatic weighing and packaging machine for packaging.
