Description
Technical Field
The invention relates to the technical field of drying of bio-organic fertilizers, in particular to an organic fertilizer drying system.
Background
The organic fertilizer comprises fertilizer formed by stacking and fermenting biomass such as animal excrement or plant remains, and dregs in the biogas digester can also be used as biological fertilizer after sterilization and deinsectization. The organic fertilizer generally contains much moisture after being subjected to the accumulated fermentation sterilization deinsectization treatment, so that the organic fertilizer needs to be dried.
The traditional low-cost method is to directly spread the biological fertilizer for airing, and the method has long drying time, uneven water content of drying and low efficiency, and can not adapt to large-scale production of the biological fertilizer gradually.
The dryer is widely used in the existing bio-fertilizer production line to dry bio-fertilizer, the drying speed of the dryer is high, the water content of materials is uniform, and the efficiency is high. But also has disadvantages: the moisture content of the bio-fertilizer is higher before the bio-fertilizer is put into the dryer, and a large amount of moisture is evaporated after the bio-fertilizer is put into the dryer, so that a lot of heat is taken away, and the resource waste is caused. Especially, the biological fertilizer in the shape of slurry has high water content and certain fluidity.
Meanwhile, in order to pursue drying speed, the existing drying equipment over emphasizes that drying is completed in one step, namely, all raw materials are put into drying equipment together for drying regardless of the moisture distribution condition of the materials, and the drying efficiency of the equipment is influenced by uneven moisture content of the materials.
In order to solve this problem, the moisture content of the bio-fertilizer needs to be reduced as much as possible before the bio-fertilizer is put into the dryer, and the less the moisture content, the higher the drying efficiency, and the less the heat loss due to evaporation.
Therefore, in order to improve the drying efficiency and reduce the energy consumption, a new organic fertilizer drying system is designed to become a problem which needs to be solved urgently.
