12,000 Tons/year Agricultural and Forestry Waste (Waste Wood, Bamboo Chips, Straw and Rice Husk) Pellet Production Line Project

The annual output of 12,000 tons of agricultural and forestry waste (waste wood, bamboo scraps, straw and rice husk) pellet production line project, converted into an hourly output is 5 tons/hour. The project mainly uses straw, branches, wood chips, bamboo chips, rice hulls, etc. as raw and auxiliary materials to build a production line. The process flow is: raw materials → crushing → drying → hopper → biomass pellet machine → inspection → product storage → finished product waiting Sale.

Biomass Pellet Production Line Project

The biomass pellets made of crop straws as raw materials are extruded at high temperature and high pressure by a biomass pellet machine. The pellets have a high density of 1.4g/cm3, short combustion temperature rise time, high flame temperature, carbon monoxide and sulfide, etc. Low pollutant emissions, full combustion and low ash content. The particle combustion value is between 4500-5000 kcal. It is smokeless and tasteless when burned. It is comparable to high-quality coal. It is an ideal new fuel and is widely used in domestic stoves, hot water boilers, industrial boilers and biomass power plants.

I. Investment and Construction Scale

This project relies on the exited pig farm buildings in Gaofeng Village, Shitang Township, Xiangyin County, and is rebuilt as the production workshop of this project. The project has a land area of ​​4200m2 and a building area of ​​about 3000m2. It will build a forming biomass pellet production line, which will produce 12,000 tons of material fuel annually, with a total investment of 6 million yuan.

Table 1-2 List of main raw and auxiliary materials types and consumption

Remarks: The raw materials of the project are mainly purchased from wood, leftover materials produced by bamboo processing companies around the project, and straws and rice husks from surrounding farmland. They are transported to the stacking workshop of the plant by vehicles and placed in a rainproof, shaded, closed raw material warehouse for storage. . Among them, raw materials such as wood and bamboo are required to be non-contaminated with organic dyes and paints.

IV. Production Line Process

Biomass Wood Rice Husk Straw Pellet Production Line

1. Crushing: Due to the large size of biomass raw materials such as crop stalks and sawdust, they cannot be directly used for forming and processing. The main task of the pulverizing process is to slice and pulverize large-sized straws, wood chips, etc., and then pass the chipper. , The crusher can compress and granulate after crushing. All raw materials of the project have high moisture content, and a small amount of dust will be generated during the crushing process. The crushed scraps are transported to the warehouse through a belt conveyor.

2. Drying: Biomass briquettes have strict requirements on the water content of the raw materials, and different requirements for different raw materials, because the initial water content of the material is 25-50%, and the water content of the pellets is 12-15 %, so a drying device should be used to dry the material to make the material moisture meet the requirements of granulation. The drying equipment uses a drum drying system. The pulverized raw materials are fed into the feeding port of the drying cylinder through the screw feeder, and the fan introduces the heat and flue gas generated by the biomass hot blast stove into the drying cylinder to dry the raw materials. The exhaust gas produced in the drying process is mainly the exhaust gas produced when the fuel is burned.

3. Forming: The pellet machine is the key equipment of the biomass forming fuel production line. The SZLH pellet machine has a high degree of automation, a large output of a single machine, and is suitable for large-scale and industrial development, so this type of molding technology is selected for this project. The main drive of the pellet machine used in this project adopts high-precision gear transmission, and the ring die adopts a quick-release hoop type, and the output can reach 1.5-2.5 tons/hour. The feeding adopts frequency conversion speed regulation technology to ensure uniform feeding.

5. Labor quota

The project plans to hire 8 laborers, all of whom are nearby residents without dormitories. The annual working days are 300 days. The production shift system is 1 shift, with 8 hours per shift.
