Embodiment Construction

[0036] refer to Figure 9 . Firstly, use molding equipment to press part of the garbage to form block garbage in the fermentation bin. Start to place from the bottom of the warehouse, the through hole of the block garbage at the starting end should be aligned with the nozzle of the steam pipe, and then put it layer by layer. The space between the block garbage is filled with loose garbage. After the block garbage and loose garbage are filled to the design height in the fermentation bin, the discharge port is sealed. The main pipeline for steam delivery is opened, and the steam is heated through the through holes of the block garbage to heat the block garbage and the loose garbage. Because the steam is evenly heated to the block garbage and the loose garbage, the garbage can be fully fermented without stirring. The biogas produced in the fermentation stage enters the gas storage tower through the purification device, one can be used as boiler fuel, and the other can be used...

Abstract

A fully-enclosed fermentation treatment process and device for urban domestic waste, which forms interconnected steam channels through block waste to promote full fermentation of block waste and loose waste, and puts the screening and sorting process in the post-fermentation and volume reduction stage. It not only saves investment in mixing equipment, but also effectively reduces the difficulty of screening and sorting. Its fermentation treatment device integrates loading and unloading, water seepage, spraying, heating, fermentation, unloading, screening, and loading into one. It has a compact and reasonable structure and is suitable for large and medium-sized garbage treatment. The processing realizes scale, systematization, productization and efficiency.

Description

technical field [0001] The invention relates to a garbage treatment method and device, in particular to a fully enclosed fermentation treatment process and device for municipal domestic garbage. Background technique [0002] A city with a population of 800,000 produces about 450 tons of municipal solid waste every day. How to effectively reduce the volume of garbage is an important issue that people have paid close attention to for a long time. [0003] The treatment of municipal solid waste by the anti-itch fermentation method not only has an obvious volume reduction effect, but also can turn the generated biogas and fertilizer into products, creating economic benefits. This method mainly puts the garbage in a closed fermentation tank, and promotes the fermentation of the garbage under certain humidity and temperature conditions. In order to make the garbage heated and fermented evenly, it is necessary to use strong stirring to make the inside and outside of the garbage t...
