Project Report On 5000 Tons Per Year Biomass Waste Wood Pellet Mill Plant For Agricultural And Forestry Wastes Pellets

Origin of the 5000 tons per year biomass waste wood pellet mill plant 

Vigorously developing renewable energy and turning waste into treasure is a major issue proposed by the State Council of China, and it is also an inevitable trend in the development of science and technology

Compared with traditional fuel, biomass fuel has low transportation cost. Biomass pellet fuel solves the problem of inconvenient transportation of biomass fuel and broadens the geographical space for biomass fuel utilization; The combustion efficiency is high and the dust pollution is low, which greatly reduces the environmental pollution caused by the direct combustion of traditional fuels.

In view of the wide range of uses of biological pellet fuel, the 5000 tons per year biomass waste wood pellet mill plant project has a very broad prospect. The biomass pellet mill plant project client, Anlong Ruijie Biological Pellet Co., Ltd., invested 3 million yuan (471000USD) to build a 5,000-ton biomass pellet production line for making wood pellets from wood waste wood sawdust wood chips wood shavings.

After the 5000 tons per year biomass waste wood pellet mill plant project is completed, 16 tons of biomass materials will be produced every day, which can promote the employment and economic development of local residents, and at the same time reuse the surrounding agricultural and forestry wastes such as waste wood, sawdust and straw.

Construction content and scale

The annual output of 5,000 tons professional complete biomass wood pellet mill plant construction project covers an area of ​​7.5 acres.

It will build standardized production workshops, raw material and finished product storage warehouses (1,600㎡ of steel structure greenhouses), office and living areas (the original living area of ​​200㎡ in the coal yard will be used) ), with an annual output of 5,000 tons of biomass pellet fuel.

Raw materials and energy consumption

The 5000t/a forestry and agriculture waste biomass wood pellet mill plant project purchased straw and leftovers, sawdust and waste wood from wood processing as raw materials. The products are obtained by crushing and pulverizing and then high-pressure molding. No auxiliary materials are added to this forestry and agriculture waste wood pellet mill plant project, and the use of paint-containing waste wood and waste straw is prohibited, the main raw and auxiliary materials used are shown in the following table:

Analysis of rationality

This forestry and agriculture waste biomass wood pellet mill plant project mainly builds finished product workshop, production workshop and raw material workshop (fully enclosed steel structure greenhouse).

The entrance and exit are located on the west side, adjacent to National Highway 324, with convenient transportation and convenient transportation of products and raw materials; the raw material yard workshop is located on the west side of the forestry and agriculture waste biomass wood pellet mill plant project.

The production workshop is located on the east side of the raw material workshop; the living area is located on the north side of the forestry and agriculture waste biomass wood pellet mill plant project.

The production workshop and product storage yard of the forestry and agriculture waste biomass wood pellet mill plant project are all closed with greenhouses; the prevailing wind direction in Anlong County is the northeast wind all the year round, and the exhaust gas discharged from the dust removal facilities has little impact on the living area.

The functional zoning in the area is clear, the pipeline transportation is short and fast, the raw materials, auxiliary materials and products are easily accessible by freight, which facilitates the reasonable layout of the biomass pellet production process.

Utilities and auxiliary works

Water supply

The forestry and agriculture waste biomass wood pellet mill plant project is for the production of biomass fuel particles. The water used in the forestry and agriculture waste biomass wood pellet mill plant project is mainly the domestic water for employees and water for water film dedusting.

There is no production waste water. The water is provided by the water pipe network of Anlong County. The water used for water film dust removal is 5m³/d, which is recycled and not discharged, and the loss rate is 2%. Fresh water needs to be supplemented with 0.1m³ every day, and the annual supplementary water volume is 30m3.

Drainage

The sewage in this biomass wood pellet mill production line project is mainly domestic sewage, and no production wastewater is produced. The proposed project has a capacity of 10 people, all of whom are nearby villagers, and will not be accommodated in the biomass wood pellet mill production line.

According to the Industrial Water Quota of Guizhou Province, if the domestic water consumption is 50L/person.d, the water consumption is 0.5m³/d (150m³/a).

Note: The wood pellet mills production line project works 300 days per year. The amount of wastewater produced is calculated as 80% of the water consumption, and the amount of domestic wastewater produced is 0.4m³/d (120m³/a).

The main pollutant factors of wastewater are COD, NH3-N, SS. The pollutant concentrations were determined as COD: 300mg/L, NH3-N: 25mg/L, SS: 200mg/L, BOD5: 150mg/L.

The domestic sewage is regularly cleaned and used as fertilizer for the surrounding farmland after being treated in the self-built septic tank in the wood pellet mill plant area, and is not discharged outside.

The rainwater on the roof of the wood pellet mill plant building is drained externally, the rest is drained internally, and the rainwater from the road surface is collected and discharged outside the wood pellet mill plant area.

Fire

The fire protection of the wood pellet mill plant project shall be implemented in accordance with the relevant provisions of "Code for Fire Protection in Architectural Design".

Biomass pellet fuel process

1. The 5000t/a biomass waste wood pellet mill plant project purchased the waste wood and sawdust from the wood processing plant as the raw material for screening.
2. The raw materials are firstly pulverized by a high quality wood sawdust hammer mill and pulverized to a certain particle size.
3. Because of the high moisture content in the raw material, it cannot meet the feeding conditions of the biomass pellet machine. The material needs to be dried by biomass sawdust rotary dryer. The pulverized raw material is then dried in a drying furnace, which burns biomass pellet fuel.

4. After drying, the material is transported to the biomass pellet granulator by the conveyor belt, and fed by the white belt feeding equipment of the wood pellet press granulator.

   Under the combined action of the wood pellet making machine and the scraper, the material is evenly spread on the ring die of the wood granulator, and then the material is extruded into the die hole, and the material undergoes the process of forming and maintaining the shape in the wood pellet making machine die hole.

   Due to the increased pressure in the wood granulator, the particles themselves undergo deformation and plastic flow, and a large amount of heat is generated under the action of friction, resulting in the softening of the lignin contained in the raw material, the increase in adhesion, and the softening of the lignin. The combined action of lignin and the inherent cellulose in the biomass makes the biomass gradually form.

   After a certain period of time, the biomass is extruded into a cylindrical shape by wood pellet press, and the wood pellet press rotating cutter cuts the pelletized biomass to form a cylindrical shape to sent out. No binder is added during the compression molding process for this 5000t/a biomass waste wood pellet mill plant project.

5. After extrusion molding by wood pellet press machine, the biofuel pellets are naturally air-dried and cooled before packaging. Packaging waste and substandard products are mainly generated in the packaging stage. The 5000t/a biomass waste wood pellet mill plant project does not produce cooling water.
6. Packaged products are ready for sale.
