Organic waste heat and recycling synchronous recycling device

Abstract

The invention relates to an organic waste heat and recycling synchronous recycling device. The organic waste heat and recycling synchronous recycling device comprises a compost reaction tank, a heat preservation water storage tank and a biogas fermentation tank, the heat preservation water storage tank is connected with a heat collecting water tank and the biogas fermentation tank, a gas collecting tank is connected to the upper part of the biogas fermentation tank, a reflux water regulating tank is connected to the middle of the biogas fermentation tank, the heat preservation water storage tank and the biogas fermentation tank are connected through a water pump, and the biogas fermentation tank and the compost reaction tank are connected through a water pump. According to the organic waste heat and recycling synchronous recycling device, organic waste is subjected to combined treatment through the composting technology and the anaerobic digestion technology, the fermentation period ofthe organic waste is effectively shortened, resource utilization of the organic waste is improved, the organic waste compost returns to the field, meanwhile biogas energy is effectively recycled, andharmless, stabilization and resource utilization of the organic waste is achieved; through improvement on the structure of the biogas fermentation tank, the stable high-temperature sterilization environment is provided, residual heat energy generated by compost is effectively recycled, and waste of resources is reduced.

Description

Technical field [0001] The invention relates to a treatment technology for solid waste treatment and resource recovery and utilization, in particular to a device and method for the treatment of organic waste involving composting and biogas fermentation and its resource recovery. Background technique [0002] With the improvement of people's living standards and the development of intensive and large-scale farming in rural areas, the amount of organic waste generated has increased year by year. If they are unreasonably treated and disposed of, it will not only harm the environment, but also cause a great waste of resources. Generally speaking, as far as my country’s current organic waste treatment and disposal technology and utilization methods are concerned, the treatment of organic waste is a high-cost and low-profit process. This reality directly leads to the low treatment rate of organic waste and many treatment facilities cannot operate normally. , The environmental pollution ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem of low recovery rate of organic waste recycling caused by residual heat energy loss of aerobic composting, low-temperature methane gas production by anaerobic digestion, etc., and provide a simultaneous recovery device for organic waste heat and recycling, And on the basis of anaerobic digestion, it is also coupled with weak electric stimulation microorganisms, by reducing the accumulation of organic acids, inhibiting the activity of methanogens, improving the degradation of organic waste, and improving the effect of methane production
