This is business proposal for 1.2 tph biomass wood chips and bamboo powder pellet plant project, which is provided by Richi Machinery in 2019.

1. Origin of the 1.2 ton capacity latest technology high quality wood bamboo pellet production line project

The harmful gases emitted from coal combustion are one of the sources of air pollution. At present, China has extended the coal ban from industrial boilers to civilian boilers and drying industries. Now it can be said that all coal burning places are banned. , China has promulgated policies and regulations for coal management year after year. Although "coal to electricity" and "coal to gas" are environmentally friendly, the increase in corporate costs is too high. Many companies that have just started to convert to gas are overwhelmed and close their doors or use biomass fuels instead of gas to reduce operating costs.

Environmental protection and low cost are the advantages of biomass fuel instead of gas. Biomass energy is energy with biomass as a carrier. At present, biomass used as energy mainly refers to wastes such as crop straw, forestry and wood processing. Biomass can be converted into high-efficiency solid, liquid and gas fuels, which can be used to replace non-renewable energy sources such as coal, oil, and natural gas. With the application of biomass boilers, the demand for biomass fuels in the market is also increasing. With the support of the country's vigorous efforts to control air pollution, the market demand for biomass fuels will continue to grow.

In recent years, with the development of China's economy, industrial demand has continued to increase, and the demand for biomass fuel pellets has increased year by year. Client-Ji'an Anlong Biomass Fuel Co., Ltd., based on market demand, invested 50000 US dollars and selected the site in the Forest Products Industrial Park, Henglong Town, Anfu County, Ji'an City, Jiangxi Province to build a project with an annual output of 3,000 tons of biomass pellets. The project covers an area of ​​1100m², with a total investment of 1 million and a total construction area of ​​1100m².

2. Project construction scale and composition

The main construction content of this 1.2 ton per hour wood pellet making plant project is workshops, office areas, warehouses and supporting facilities, and it is mainly engaged in the production and sales of biomass fuels.

3. Product plan

The product of this 1.2 ton reasonable design biomass fuel wood bamboo pellet production project is mainly biomass pellets, and the product plan of the project is shown in the following table:

4. Main equipments needed in 1.2t/h biomass pellet making plant for wood chips and bamboo powder

5. The main raw and auxiliary materials of the 1.2 ton fuel pellet manufacturing line project

Physical and chemical properties of raw and auxiliary materials:

①Bamboo powder: Bamboo powder has a wide range of uses and is a new energy-saving and environmentally-friendly raw material. It can be used as a raw material for various products such as bamboo and plastic products, mosquito coils, leather, clothing, papermaking, electrical appliances, daily necessities, coatings, cat litter, chemicals, insulating materials, outdoor decoration materials, building materials and so on.

②Sawdust: Sawdust refers to the sawdust and shaving powder left during wood processing. It is mainly used as fuel and lightweight bone filler, or composited into man-made boards, such as medium-density board. It can also be used as a raw material for papermaking.

③Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry wastes (such as straw, sawdust, bagasse, rice bran, etc.). Mainly different from fossil fuels. Biomass fuel has a large calorific value, the calorific value is about 3900-4800 kcal/kg, and the calorific value after carbonization is as high as 7000-8000 kcal/kg. Biomass fuel has high purity and does not contain other sundries that do not produce heat. Its carbon content is 75-85%, ash content is 3-6%, and water content is 1-3%. It is absolutely free of coal gangue, stones, etc., instead of heating. Heat-consuming impurities will directly reduce costs for enterprises.

Biomass fuel does not contain sulfur and phosphorus, does not corrode the boiler, and can extend the service life of the boiler, and enterprises will benefit a lot. Because biomass fuel does not contain sulfur and phosphorus, it does not produce sulfur dioxide and phosphorus pentoxide during combustion, so it does not cause acid rain, does not pollute the atmosphere, and does not pollute the environment. Biomass fuel is clean and hygienic, convenient to feed, reduces the labor intensity of workers, greatly improves the labor environment, and enterprises will reduce the cost of labor. After the biomass fuel is burned, there is very little ash and ballast, which greatly reduces the site for stacking coal and reduces the cost of ballast. The ashes from the burning of biomass fuel are high-quality organic potash fertilizers that can be recycled for profit.

11. Complete 1.2 ton per hour bioamss wood bamboo pellet manufacturing process flow

Purchased raw materials-screening-crushing-drying-granulating-cooling-packaging and warehousing

The raw and auxiliary materials of the project, bamboo powder and wood chips, are purchased nearby, with a moisture content of ≤20%, and the raw materials are collected and stacked in the raw material storage yard for later use.

(1) Screening: The raw materials bamboo powder and wood chips are screened by a drum screen, and are mainly used for the sorting of raw materials. The sieve hole of the rolling screen is about 1 cm. Large pieces of material enter the biomass materials hammer mill crusher, and small pieces of material directly enter the wood pellet maker.

13. Environmental impact analysis during operation period

(1) Exhaust gas

The air pollutants produced by this project are mainly dust and drying waste gas. The dust is discharged by 15m exhaust cylinder 1# after being processed by the air collecting hood + bag filter, and the drying waste gas is processed by the induced draft fan + bag filter. It is discharged by 20m exhaust cylinder 2#, and can meet the emission standards after treatment. Therefore, the waste gas during the operation period of this project has a relatively small impact on the environment within the assessment scope.

(2) Wastewater

No production wastewater was generated during the operation period of the project. The main water used was domestic water. After being treated in septic tanks, it will be used for irrigation of surrounding forest land after reaching the standard in Table 1 of the "Farmland Irrigation Water Quality Standard" (GB5084-2005). Slight impact on the environment. Therefore, the project sewage has little impact on the water quality and environment of the surrounding waters.

(3) Noise

In the project, measures such as sound insulation cover and foundation damping are added to each equipment, and regular maintenance is performed. The noise emission meets the "Environmental Noise Emission Standard for Industrial Enterprises and Plant Boundaries" (GB12348-2008) Class 2 zone standard. Therefore, the noise during the operation period of this project has a small impact on the environment within the assessment scope.

(4) Solid waste

The solid waste generated during the operation of this project is general solid waste and domestic waste. General solid wastes are collected by dust collectors, collected and handed over to the sanitation department for unified treatment. The domestic garbage is handed over to the sanitation department for unified disposal. Therefore, all solid wastes generated in this project are effectively disposed of and have little impact on the environment within the scope of the assessment.
