Product Plan

Utilities Of The Bamboo Wood Chip Pellet Mill Plant

Water supply

Water supply: There is no production water in this 1-1.2tph best price good small bamboo wood chip pellet mill plant project, and the main water is for employees' domestic use. Drinking water for employees is provided by purchasing large barrels of water produced by local drinking water plants, and other domestic water comes from local spring water.

Water consumption: In view of the fact that the employees of this 1-1.2tph best price good small bamboo wood chip pellet mill plant project are not accommodated in the factory area, so the water consumption quota for the office with a canteen is 80L/person, and the office water consumption quota for the office without a canteen is 80L/person. 45L/person.

This 1-1.2tph best price good small bamboo wood chip pellet mill plant project has a total of 4 people, and the water quota is 45L/person·d, so the domestic water consumption is 0.18m³/d, 54m³/a.

Drainage

The rainwater and sewage are separated, and the rainwater flows from the rainwater ditch inside the 1-1.2tph best price good small bamboo wood chip pellet mill plant site into the rainwater side ditch of the road outside the site, and enters the local agricultural irrigation system;

There is no production wastewater discharge in this 1-1.2tph best price good small bamboo wood pellet plant project, and a small amount of domestic sewage is calculated based on 80% of the domestic water consumption. The production amount is 0.144m³/d, 43.2m³/a.

The employees of this 1-1.2tph best price good small bamboo wood chip pellet mill plant project are local villagers, and the number of employees is small. The bamboo chips wood chips pellet plant does not arrange accommodation and canteens.

The domestic sewage generated by the 1-1.2tph small bamboo wood chip pellet mill plant project is collected and treated by renting a dry toilet in a 2-story office building in Huitong County State-owned Forest Farm on the east side of the 1-1.2tph best price good small bamboo wood chip pellet mill plant project. For the surrounding agricultural and forestry watering, do not discharge.

Power supply system

The electricity for the small bamboo wood chip pellet mill plant project is provided by the power grid of Huitong County Electric Power Company, which can meet the needs of the project.

Heating, gas supply

There is no boiler in this small bamboo wood chip pellet mill plant project. The heat energy required for the production of the small bamboo wood chip pellet mill plant project is provided by the hot blast stove. The fuel uses the biomass pellet fuel produced by the bamboo wood chip pellet mill plant project.

Fire

According to the "Code for Fire Protection in Architectural Design" and the relevant regulations of the local fire department, do a good job in fire safety.

Process flow Of The Bamboo Wood Chip Pellet Mill Plant

1. Sifting section

   The purchased powdery bamboo chips and sawdust raw materials may contain a small amount of wood, bamboo, branches and other impurities due to different sources, which need to be screened out through the sieving process.

   The sieved wood blocks, bamboo blocks, branches and other impurities are collected and handed over to the raw material supplier for reprocessing.

2. Drying section

   Because the moisture requirement of the biomass pellet fuel products produced in this small bamboo wood chip pellet mill plant project is controlled below 18%, the purchased powdery bamboo chips and wood chips have high moisture content.

   So it is necessary to dry the moisture through the drying process with a wood bamboo chips drying equipment before entering the granulation stage. The heat source required for drying is provided by a hot blast stove, and the fuel is biomass pellet fuel.

3. Pelletizing section

   The dried powdery bamboo chips and wood chips are extruded through a ring die 520 wood pellet press granulator without any additives or adhesives.

   The partially broken defective products produced during the bamboo wood chips granulation process and the granulation dust recovered by the 9-barrel bag filter that comes with the wood pelletizer are collected and reused for the production of biomass pellet fuel products.

Main Pollution-Producing Links

Exhaust gas

This small wood bamboo chip pellet mill plant project does not have a crushing workshop, and the project's waste gas emissions are mainly the dust generated in the granulation process and the flue gas generated by the hot blast stove in the drying process.

The amount of fugitive emission of dust generated in the material conveying process of material unloading, screening, drying, granulation and other production links, and the material fugitive dust generated by the action of wind at the outlet of the dryer are small, and have little impact on the environment.

This small wood bamboo chip pellet mill plant project is small in scale and has no crushing process. The required powdery biomass materials such as bamboo chips and wood chips are provided by local raw material suppliers. The raw material has a coarse particle size and a large water content.

The production of biomass pellet fuel adopts professional equipment The ring diepellet chips production line provided by the Richi Machinery, the biomass pellet making machine such as sieving, drying and granulation are all sealed equipment or have their own dust removal facilities;

The inlet and outlet of the rotary dryer for biomass wood chips are equipped with a closed air device. The amount of dust generated at the outlet of the wet sawdust drying equipment is less due to the action of wind.

The material conveying between processes is conveyed by conveyor belt, which has a high degree of automation. The amount of unorganized dust generated during the conveying process of production links such as feeding, screening, drying, and granulation is very small, and the impact on the environment is small.

Wastewater

There is no production wastewater, and the wastewater is mainly domestic sewage of employees.

Noise

It is mainly the noise generated by the operation of mechanical equipment. The scale of this small bamboo wood chip pellet mill plant project is relatively small, and the noise value is between 65 and 75dB(A) compared to the 5,000-ton biomass pellet mill plant project in Jieyang, Guangdong.

Solid waste

Mainly for the domestic waste of employees, impurities such as wood blocks, bamboo blocks, branches and other impurities screened out of raw materials, broken and defective products produced by granulation, granulation dust recovered by bag filter, hot blast stove ash, and recycled smoke.
