Multifunctional dry fermentation library

Abstract

The invention relates to a multifunctional dry fermentation bank which comprises a bank body. The bank body is divided by a partition plate into an upper material fermentation area and a lower leachate storage area. A plurality of filter holes are formed in the partition plate. A biogas slurry spraying system is installed on the top of the bank body and communicated with the leachate storage area. The biogas slurry spraying system comprises a pipeline and a plurality of spraying nozzles. An electromagnetic valve is arranged between each spraying nozzle and the pipeline. An adsorption diversion device capable of horizontally reciprocating is arranged above filtrate of the leachate storage area, and comprises a plurality of hopper-shaped adsorption covers. The openings of the adsorption covers face upwards and are covered with opening face plates. A plurality of air guide holes higher than the opening face plates are formed in the opening face plates. The adsorption covers are communicated with the top of the material fermentation area through an anti-explosion fan. By means of the fermentation bank, heat transfer and mass transfer efficiency in a fermentation material is improved, the precise area control in the fermentation process is achieved, local acidification of the fermentation raw material is prevented, and efficient and stable running of dry fermentation is ensured.

Description

technical field [0001] The invention relates to a multifunctional dry fermentation storage, which belongs to the technical field of biomass energy utilization. Background technique [0002] The solid content of the dry fermentation material is high, the fluidity is poor, and the uniformity is not ideal, which makes it difficult to infiltrate the biogas slurry during spraying, and the heat and mass transfer process inside the fermentation material is slow. A large amount of organic acid accumulates in the medium, and the dilution is not timely, so that the fermentation raw materials are partially acidified, the growth and metabolism of microorganisms are out of balance, resulting in low efficiency of biogas production, and even fermentation failure. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the disadvantages of the above-mentioned technologies, and provide a dry fermentation storehouse which can make the i...
