Small-scale kitchen waste garbage methane system

Abstract

The invention provides a small-scale kitchen waste garbage methane system, and belongs to the technical field of biological fermentation. The small-scale kitchen waste garbage methane system comprisesa charging pretreatment device, an S-shaped water sealing pipe, a raw material storing device, a charging control valve, a methane generation device, a methane purifying device and a methane storingdevice which are sequentially connected. From collection of kitchen waste garbage subjected to anaerobic fermentation to produce methane, to methane purification and storage and to final conveyance tousers, whole-course closed loop operation is realized, and resourceful and innocent treatment of the kitchen garbage can be effectively realized. According to the small-scale kitchen waste garbage methane system, automation control is realized in the whole course, man-made excessive intervention is not needed, and the small-scale kitchen waste garbage methane system is safe and reliable and highin applicability.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a small kitchen waste biogas system. Background technique [0002] With the improvement of people's material and cultural life, domestic garbage, especially kitchen waste, is produced in large quantities. If these kitchen wastes are not properly disposed of, they will bring about many problems, such as the breeding of fly insects, foul odors, and even secondary pollution. At present, the mainstream treatment method for kitchen waste is to bury it after dehydration. This treatment method not only does not effectively use kitchen waste, but also easily leads to groundwater pollution. [0003] The resourceful and harmless treatment of kitchen waste has become the mainstream direction of current research. Bio-fermentation biogas production is a technology that uses microbial groups to digest organic materials in an anaerobic environment to prepare biogas...

AI Technical Summary

Problems solved by technology

[0004] However, every household produces kitchen waste, which is widely distributed and produced intermittently, and cannot be continuously and stably supplied for production

And because the amount of kitchen waste generated by households is relatively small, it is usually thrown away together with other household waste, which is not conducive to the resource utilization of kitchen waste

In addition, in the process of collecting and storing kitchen waste, flies breed and emit peculiar smell, which has become a disadvantage in the process of using kitchen waste to produce biogas
