Static aerobic fermentation reactor for domestic garbage

Abstract

The invention relates to a static aerobic fermentation reactor for domestic garbage. The reactor comprises a fermentation cabin, drainage and ventilation pipes and air blowers, wherein the fermentation cabin has a three-grid type masonry-concrete structure and is enclosed by a main wall and side walls formed at equal intervals; according to the reactor, the drainage and ventilation pipes, main drainage and ventilation pipes and U-shaped drainage pipes are respectively arranged on the ground outside the main wall of a three-grid cabin body correspondingly in a connection mode; the ground of the fermentation cabin is inclined towards outlets of the U-shaped drainage pipes; a drainage and ventilation groove is formed on the ground in each grid of the cabin body parallel to the side walls; cover plates are arranged on the upper end surfaces of the drainage and ventilation grooves respectively; the drainage and ventilation grooves are communicated with the drainage and ventilation pipes corresponding to the drainage and ventilation grooves at the intersections of the bottom of the main wall; the other ends of the drainage and ventilation pipes are communicated with the main drainage and ventilation pipes arranged on the outer side of the main wall; the air blowers are connected to the tail ends of the main drainage and ventilation pipes parallel to the outer side of the main wall; and one U-shaped drainage pipe is vertically arranged on one side of each main drainage and ventilation pipe in a connection mode. The reactor has a simple structure and low cost, is easy and convenient to use and maintain and effectively improves the composting efficiency of produced garbage.

Description

Technical field [0001] The invention relates to a domestic waste fermentation reactor, in particular to a domestic waste static aerobic fermentation reactor. Background technique [0002] At present, domestic waste composting is an important way of waste resource treatment. However, because waste composting must be classified first, and then fermented in a fermentation bin, it is especially suitable for rural waste treatment with high compostable content. Static aerobic fermentation technology often uses indoor tunnel fermentation in large waste composting sites. Because it is not interfered by external factors such as rain, there is a PVC ventilation pipe at the bottom of the fermentation tunnel, and ventilation holes are set above the pipe, and ventilation is controlled by valves. Once the pores are blocked by oxygen, maintenance is very difficult. [0003] The existing three-format fermentation bin is widely used in the field of small and medium-sized domestic waste composting,...

AI Technical Summary

Problems solved by technology

Since PVC drainage and ventilation pipes are easy to block during long-term use, resulting in uneven wind distribution and uneven oxygen supply, which directly affect the fermentation effect, and at the same time the blocked pipes are difficult to clean; The garbage is emptied, and the blower is turned on to blow through the blocked part by wind. It is difficult to clear the blocked pipes by wind. It is necessary to fully inspect the blocked pipe section and replace the PVC ventilation pipe; therefore, the later maintenance is very complicated, and the replacement of the pipe is very complicated. , The system cost and maintenance cost are very high, and the cleaning time is long, which directly affects the normal application of the reactor
