Business proposal for a large capacity annual output of 20,000 tons biomass wood waste pellet production plant in China

1. Project background

The annual output of 20,000 tons large size antomatic wood pellet plant project started construction in late August 2015 and was completed and put into production in late October 2015. The construction period is 60 days. It is located in Datong City, Shanxi Province, China. The area has a forest area of ​​270841.4 hectares and a forest stock of 24357716 cubic meters. , The forest coverage rate is 75.15%. The country has issued a forest logging quota of 58,000 cubic meters each year, and the output of commercial materials is 28,000 cubic meters. The cumulative storage of pier roots, tree heads, branches, tree roots, wind-fallen wood and other residues is about 1.5 million tons. Dumping in the forest wastes resources and pollutes the environment.

In order to adjust the forestry industry structure, stimulate regional economic development, increase the utilization rate of residues in cutting areas, and increase the economic income of forest farms and forestry workers. According to the national plan for the development of biomass energy, combined with the actual situation of the remaining residues in the logging area, it is necessary to crush the wood waste generated in the logging area into wood pellet fuel for reuse.

(5) Wood pellet manufacturing process

The 20000 tons per year big wood pellet line manufacturing process is: raw material → crushing → natural drying → lifting and warehousing → iron removal → high temperature compression → cooling → packaging → storage → transportation.

Raw materials must be strictly inspected when entering the site, and the moisture content must be controlled within 23%. After the raw materials enter the site, they are stacked and dried according to the size of the wood diameter, and the height of the loader must be used to reduce the occupation of the space.

Before crushing, the moisture of the wood should be controlled below 20%. According to the size of the wood diameter, different types of crushers are used for crushing. After crushing, it is naturally air-dried in the shed. When the moisture reaches 11%-15%, use the loader to load the material and lift it into the silo; the silo is equipped with a level meter to control the loading of the hoist to prevent the hoist from being stopped when the silo is full; Magnetic cylinder, remove the iron from the scraps.

The working principle of the ring die high quality biomass wood pelletizer machine is similar to the existing forage grass feed pellet mill machine, that is, the raw materials are added from the ring die (the moisture content of the raw materials is required to be 11% to 14%, and the moisture content is too large or too small. It is not good to be granulated), which is rolled and extruded through a ring die to form granules. The extrusion pressure reaches 50-100MPa. The raw material deforms and rises under high pressure, and the temperature can reach 100-120℃.

After the pellets are made, they are lifted into the warehouse by a belt conveyor, and then cooled and sieved by a cooling unit. After screening, the particles that do not meet the specifications are recovered and returned to the silo. Qualified particles are loaded by the elevator to the silo to be packaged, and packed by the computerized quantitative packaging machine, and then stored and sold in the warehouse.

(6) Staffing

The high quality wood pellet line with big capacity is divided into three sections: crushing section, granulating section and packaging section. Implement an 8-hour work system. The crushing section and the granulating section operate in 3 shifts a day, each with 5 people, including 1 loading machine (raw material in the crushing section, wood chips on the pelletizer), 2 crushing and feeding workers, and 2 granulating operators. Four shifts are operated in three shifts, with a fixed number of 20 people; the packaging section operates two shifts a day, each with 3 people, including 1 packaging operator and 2 movers, implementing three shifts and two operations, with a fixed number of 9 people; company management personnel and auxiliary production The staff will be 14 people. The company has a total of 43 employees.

4. Social and ecological benefits

With the continuous progress of forestry production, residues accompanying the logging, timber and processing processes are also inevitable. The "three remnants" in the forestry production process have always been a problem that plagued forestry production. These leftovers are piled up in the forest. Not only do they need to be cleaned up, but the "three leftovers" after the cleaned up have to be burned at designated locations. This not only consumes a lot of manpower and material resources, but also increases the burden of fire prevention in the already stressful forest area during burning. If it cannot be cleaned up in time, the leftovers will rot and deteriorate, which will cause forest diseases, insects, and pests.

The implementation of the wood pellet industrialization project puts forward a solution to this problem. It not only collects residues, reduces forest pollution, reduces forest fire protection hazards, but also solves forest production and living use. The fuel issue provides the society with high-quality environmentally friendly energy, promotes the development of forestry industrialization, and brings economic and social benefits. In the production process of wood pellets, all mechanized operations are realized, and the whole production process is mainly based on electricity and mechanical power, without any pollution. Every year, 10,000 to 20,000 tons of logging residues in the local forest area can be used to bring 1.066 million yuan of forest clearing labor and transportation income to the local area, and to pay 538,000 yuan in taxes. It can also provide 43 relatively stable jobs for the local area, bring annual wages of 875,800 yuan to employed employees, and stimulate the development of local transportation and related service industries.

The implementation of this project complies with China's Renewable Energy Law and the Renewable Energy Development Plan and the State Forestry Administration's plan and requirements for the development of the biomass energy industry. It can provide the society with 20,000 tons of renewable clean energy every year. Really do work for building an environment-friendly society. Change the way the local and surrounding areas use coal for production and life, gradually replace coal with clean fuel wood pellets, reduce environmental pollution, and build clean forest areas. After the successful experience of the project, the 20000 tons per year completely automatic running wood pellet production line project for biomass pellets will be popularized, the industry will be bigger and stronger, and wood pellet production will become an important part of regional forestry production. Forestry production, residue cleaning, and wood pellet clean energy production will be carried out together.
