Embodiment 1
[0022] During production, it is necessary to prepare raw materials, such as sawdust, peanut skins, crop stalks, and bark raw materials, and then pile up and ferment the raw materials; after piling up, carry out coarse crushing, respectively coarsely crush the above-mentioned prepared raw materials, and crush them for later use; At the same time, the raw materials are screened, the larger raw materials and foreign objects are picked out, and the larger raw materials are crushed for the second time, which is convenient for later operation; the crushed raw materials are put into the mixing dryer for mixing and drying, and the mixing and drying are carried out at the same time , When mixing, use the stirring paddle to stir to make it fully mixed, and at the same time it can be convenient for drying, and the mixing and drying are carried out at the same time, which greatly saves the operation time; the dried raw materials are finely pulverized, and the particle size of the processed ...

The invention provides a production process of a biomass granular fuel, wherein the production process comprises the specific technological process: raw material preparation, coarse crushing, screening, mixing, drying, fine crushing, extrusion granulation and cooling. The operation process is simplified, coarse crushing and screening processes are combined together, mixing and drying are combined together, and conveying and cooling are combined together, so the operation time is shortened while the operation effect is improved, and the production efficiency is improved; the fine crushing operation is further increased, excessive large crushed particles are avoided, and the granulation normal running of an extruder is ensured. Raw material after fine crushing is subjected to humidity detection, when the humidity is lower than forming humidity, the humidity is increased by using a humidifier, the humidity of the raw material is guaranteed to be suitable for granulation, and then the raw material after fine crushing is transported into the extruder for granulation; formed granules are put into a conveying belt for conveying, and are cooled by a cooling device in the process of conveying, so that cooling is more uniform while the time is saved.
Description
technical field [0001] The invention relates to the field of biomass fuels, in particular to a production process of biomass particle fuels. Background technique [0002] Biomass fuel is a new type of fuel. It is a clean and low-carbon renewable energy. As a boiler fuel, it has a long burning time, a high temperature in the enhanced combustion furnace, and is economical and non-polluting to the environment. It is an alternative High-quality environmentally friendly fuel for conventional fossil energy. The existing production process of biomass pellet fuel is relatively complicated, and the production efficiency is low. During the production process, it is easy to have insufficient humidity during extrusion, resulting in failure to successfully pelletize. Contents of the invention [0003] According to the above technical problems, the present invention provides a production process of biomass pellet fuel, and its specific process flow is: [0004] (1) Raw material prepar...
