[0038] like figure 1 Shown, it is the first embodiment that the present invention relates to a kind of biomass particle fuel production process, and it comprises the steps:

[0039] ①Material pretreatment: the material is screened, dried and cyclone separated and then stored;

[0040] ② Stirring, material distribution and granulation: After the above-mentioned stored materials are fully stirred, they are distributed to several different granulators for granulation;

[0041] ③Dedusting and screening to obtain finished products: the biomass particles formed by granulation are subjected to dust removal treatment, and then screened to select qualified products.

[0042] More preferably, the production process also includes:

[0043] ④ Transport the unqualified products screened out to step ② through the conveying mechanism for re-stirring. In this way, biomass particles with unqualified length can be reused, thereby saving costs.

[0044] like figure 2 Shown, it is the second embodiment that the present invention relates to a kind of biomass particle fuel production process, and it comprises the steps:

[0045] ①Material pretreatment: Screen, dry and cyclone separate the materials with different degrees of softness and hardness, and then store them;

[0046] ② Metering and mixing: with the aid of the metering hopper, materials of different degrees of softness and hardness are added together in a certain proportion, and mixed evenly after stirring;

[0047] ③Separation and granulation: distribute the evenly stirred mixture to several different granulators for granulation;

[0048] ④After dust removal and screening, the finished product is obtained: the biomass particles formed by granulation are subjected to dust removal treatment, and then screened to select qualified products.

[0049]Compared with the first embodiment, the second embodiment can combine different degrees of softness and hardness of v...

Abstract

The invention discloses a technique and a device for producing biomass pellet fuel. The technique comprises the following steps: (1) preprocessing materials: storing the materials after sieving, drying, and cyclonic separation; (2) stirring, separating the materials and granulating: after fully stirring the stored materials, separating the materials into a plurality of different granulators for separate granulation; and (3) dedusting and sieving to obtain finished products: dedusting biomass pellets formed in granulation, and then sieving to select qualified products. The device comprises successively-arranged preprocessing equipment, a stirring machine, a material separator, at least two granulators, a deduster, a finished product sieve, a finished product belt machine, and a finished product bin. Compared with the prior art, the technique and the device can produce biomass pellet fuel with high quality, and have high production efficiency and low fault rate.

Description

technical field [0001] The present invention relates to the field of biomass pellet fuel manufacturing, and more specifically relates to a biomass pellet fuel production process and equipment. Paint baking, aluminum melting, die casting and drying processes. Background technique [0002] China is a country with a large population and a country with rapid economic development. In the 21st century, it will face the dual pressure of economic growth and environmental protection. Therefore, changing the way of energy production and consumption, and developing and utilizing renewable clean energy resources such as biomass energy are of great significance to establishing a sustainable energy system, promoting national economic development and environmental protection. [0003] The development and utilization of biomass energy is of special significance to rural China. 80% of China's population lives in rural areas. Biomass energy such as straw and firewood is the main living fuel ...
