Waste gas treatment
|The raw material storage, transportation, loading and unloading dust, product storage, transportation, loading and unloading, and packaging dust generated by this project are discharged in an unorganized form after settlement in the workshop; the granulating dust is treated by cyclone dust collector + bag dust removal and settles in the workshop. Then it will be discharged in an unorganized form.
Reduce unorganized dust emissions from the project by strengthening management and other measures.
|This project does not need water for production, and no production wastewater is produced. Domestic sewage is treated in a
tertiary septic tank and used for vegetable fertilization.
|Rational distribution, use low noise device, damping sound insulation to take measures to strengthen equipment maintenance

|Relying on engineering||Yiyang municipal solid waste incineration hair
|Yiyang Municipal Solid Waste Incineration Power Plant is located in Qingshan Village, Xielingang Town, Yiyang City, Hunan Province, with a total area of 60,000 square meters, or 90.0 mu. The total investment is 50.46 million yuan, and the service scope covers the main urban area of Yiyang City and some surrounding towns and towns and the eastern new district. The mechanical grate furnace incineration process is adopted, and two 400t/d waste treatment production lines are selected.|

This project relies on the existing engineering labor quota, no more new employees, 5 production employees, one-shift system, each shift is 8 hours, and the annual work is 300 days. No board and lodging are provided.
The production process of this project is relatively simple. All processes are physical processes. Rice Husk Pellet Machine: the rice husk in the raw material storage yard is transported to the Pellet Machine equipment through the sealed auger. The principle of the granulator is that the fine material is crushed and squeezed by rollers. It is deformed and extruded under high pressure into pellets without any additives.
(1) Raw materials
The raw materials of the project are transported by vehicles to the raw material storage yard for backup, and a certain amount of dust is generated during the raw material transportation.
(2) Pellet Machine
The rice husk raw materials of this project do not need to be crushed, and can directly enter the granule machine-made Pellet Machine. The raw material for biomass Pellet Machine is only rice husk without any additives. The Pellet Machine process generates dust and noise of the granulator.
Rice Husk Pellet Machine
The compressed biomass pellets generally have a temperature of 40-50°C, and they need to be cooled in the case of packaging. The pelletized product is transported to the finished product yard by a conveyor belt for natural cooling, and then packaged after cooling. The packaging process of this project is manual packaging .
The raw materials purchased in this project are all dried rice husks with a moisture content of about 8%. The project will no longer dry the raw materials. The formed biomass fuel is small in size, large in specificity, resistant to combustion, and convenient for storage and transportation.
