Method and device for treating kitchen waste

Abstract

The invention discloses a method and equipment for treating kitchen waste, comprising a feeding module connected to each other, a fermentation module, a heating module, an oil-water separation module, a screening module, a granulation module, a waste treatment module, and an output end of the feeding module It is connected with the input end of the fermentation module, and the heating module is arranged around the fermentation module to control the temperature in the fermentation module. One of the output ends of the fermentation module is connected with the input end of the oil-water separation module, and the other output end of the fermentation module is connected with the screening The modules are connected, and the solid materials processed by the fermentation module are screened by the screening module. The output terminal of the screening module is connected with the input terminal of the granulation module, and the waste output terminal of the fermentation module, automatic screening module and oil-water separation module is connected with the waste The input terminal of the object processing module is connected. The invention realizes the integrated treatment and precise fermentation of the kitchen waste, avoids the pollution and transshipment of the separated oil liquid, and reduces the operation cost of the kitchen waste treatment.

Description

Technical field [0001] The invention belongs to the field of environmental protection, relates to the treatment of kitchen waste, in particular to a method and equipment for treatment of kitchen waste. Background technique [0002] Food waste includes two categories: food waste and kitchen waste. With the continuous growth of the global population base and the improvement of people's living standards, the emission of food waste is increasing. Kitchen waste comes from the daily lives of households and is characterized by a relatively large amount. The main difference between food waste and ordinary waste is the high moisture content and high organic content of food waste. [0003] At present, the existing commonly used technologies include aerobic microbial degradation treatment, high-temperature composting and anaerobic digestion treatment and other resource utilization technologies, but the above-mentioned methods require pre-procedures such as manual screening, primary crushing...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: to provide a method and equipment for processing food waste, which are used to solve the problem of many pre-procedures, complicated process and low degree of automation in the existing method for processing food waste, and the problems of screening, primary crushing, Pre-procedures such as water washing and degreasing are likely to cause secondary pollution, and the biodiesel generated during the treatment process is not effectively used, and the actual resource utilization is low.
