Embodiment Construction

[0020] like figure 1 As shown, the preparation process of a kind of biomass particle fuel of the present invention, first adopts crop stalks, agricultural and forestry wastes as raw materials, feeds raw materials into pulverizer and pulverizes, and makes raw material particle size be 4~5mm, sends pulverized raw materials to into the feed port of the biomass pellet fuel granulator for compression molding, and the compressed pellet fuel is directly sent to the baler for packaging.

[0021] like figure 2 and image 3 As shown, it is a pelletizer for biomass pellet fuel in the present invention, including a feed port 3 and two ring dies 1, the two ring dies 1 are circumscribed cylinders and rotate in opposite directions, and the feed port 3 is located in the two ring dies 1 directly above the tangent point, each ring die 1 is evenly distributed with a number of pressing through holes 2, and the pressing through holes 2 on the same vertical section are all facing the center of t...

Abstract

The invention discloses a preparation process for producing biomass pellet fuel which has four steps of choosing materials, crushing, granulating and packing, and at the same time discloses a biomass pellet fuel granulating machine used in the process, comprising two circular moulds. The two circular moulds are presented in circumscribed cylinder and are oppositely rotated. A plurality of pressing through holes is uniformly distributed on each of the circular mould. The pressing through holes on the same vertical section are all direct towards the circular mould center of the section. The pressing through holes are alternatively distributed on the tangency place of the two circular moulds. The preparation process effectively reduces the energy consumption. The unit energy consumption in the entire pellet production process is 25-60kWh/t, and compared with the traditional processing the energy consumption is reduced more than 70 percent. At the same time, the pellet can be made once when the humidity is 10-35 percent, which the drying procedure is saved. After the pellet is made, the temperature is just risen 10-15 centigrade. The temperature of the pressed pellet is generally 55-60 centigrade. The pellet can be directly packaged without cooling. The cooling procedure is saved and the working efficiency is improved.

Description

technical field [0001] The invention relates to a fuel preparation process and production equipment, in particular to a biomass particle fuel production process and a granulator used in the process. Background technique [0002] Fossil fuels such as coal, oil, and natural gas are the core energy sources of industrial society, but they are non-renewable resources with limited reserves. According to statistics from the International Energy Agency, coal, oil, and natural gas can be exploited for only 240, 40, and 50 years, respectively. With the rapid development of human economy and society, the speed of energy consumption is getting faster and faster, especially the increasing consumption of fossil fuels, which leads to their over-exploitation, which makes the prices rise and gradually become exhausted; at the same time, high-intensity utilization A large amount of excess energy and carbon are released, which breaks the energy and carbon balance of nature, causing the destru...
