Dry anaerobic fermentation treatment equipment for high-content organic solid waste

Abstract

The invention discloses dry anaerobic fermentation treatment equipment for high-content organic solid waste. The equipment comprises a feed hopper, a crushing chamber, a crushing device, a dry anaerobic fermentation machine body and socles, wherein the socles are vertically connected to the bottom of the dry anaerobic fermentation machine body, the feed hopper is connected to the top of the dry anaerobic fermentation machine body, the feed hopper is communicated with the crushing chamber, and the crushing chamber is provided with the crushing device connected with the dry anaerobic fermentation machine body. Compared with the prior art, the equipment is advantaged in that alternate pulverization is performed, a scraping sleeve is taken as a static tool, a pulverizing knife is taken as a moving tool, so the organic solid waste attached to the crushing knife can be scraped in time; the situation that more organic solid waste is attached to surfaces of pulverizing cutters, and pulverizingof the organic solid waste is consequently affected is avoided, the pulverizing quality of the organic solid waste of the pulverizing cutters is improved, the organic solid waste is pulverized more thoroughly, follow-up anaerobic fermentation of the organic solid waste is facilitated, moreover, equipment does not stop, and pulverizing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of anaerobic fermentation, in particular to a dry anaerobic fermentation treatment equipment for high-content organic solid waste. Background technique [0002] Organic solid waste is not suitable for direct landfill and incineration because of its perishable, odorous and biodegradable characteristics. At present, the treatment of organic solid waste is mainly anaerobic fermentation. Anaerobic reactions are divided into "wet anaerobic" and "dry anaerobic" There are two types of anaerobic fermentation, and dry anaerobic fermentation should be used for high-content organic solid waste, which can save energy consumption and operating costs. [0003] Since the particle diameter of organic solid waste is slightly larger, in order to promote the decomposition of organic matter, it is necessary to pulverize and cut the organic solid waste during anaerobic fermentation treatment. When the pulverizer is pulverizing a...

Problems solved by technology

[0003] Since the particle diameter of organic solid waste is slightly larger, in order to promote the decomposition of organic matter, it is necessary to pulverize and cut the organic solid waste during anaerobic fermentation treatment. When the pulverizer is pulverizing and cutting, the organic solid waste is easy to adhere to the surface of the pulverizer. Long-term crushing will lead to more and more organic solid waste attached to the surface of the pulverizer, which will reduce the contact area between the pulverizer and the organic solid waste, which will affect the quality of the organic solid waste, resulting in incomplete and incomplete comminution of the organic solid waste. Uniformity, which in turn affects the subsequent anaerobic fermentation
