Multiple-effect purification device for animal manure methane gas

Abstract

The invention discloses a multiple-effect purification device for an animal manure methane gas. The multiple-effect purification device for the animal manure methane gas comprises a shell, a dewatering module arranged in the shell and used for dewatering the methane gas, and a purification module arranged in the shell and used for comprehensively purifying the methane gas. The dewatering module comprises a first water removal device and a second water removal; the purification module comprises a first deodorization device, a second deodorization device and a comprehensive purification device;and the first deodorization device, the first water removal device, the second deodorization device, the second water removal device and the comprehensive purification device are connected sequentially. The multiple-effect purification device for the animal manure methane gas provided by the invention is reasonable in overall structure design and can achieve the aims on effective deodorization andpurification for the animal manure methane gas by adopting the alternate connection treatment of a water storage module and the purification module; and meanwhile, the adopted structure is small in occupied area, low in manufacturing cost, and suitable for small-scale animal manure methane gas purification treatment.

Description

technical field [0001] The invention relates to the technical field of biogas purification equipment, in particular to a multi-effect purification and purification device for livestock and poultry manure biogas. Background technique [0002] With the rapid development of livestock and poultry breeding industry, the pollution of livestock and poultry breeding waste to the environment has exceeded the sum of environmental pollution caused by industrial and urban domestic sewage discharge. A large number of livestock and poultry breeding pollutants that need to be dealt with have seriously affected the local ecology environment, resulting in the deterioration of the ecological environment. The biogas project is a systematic project that integrates manure treatment, biogas production, and resource utilization. It is the main means of intensive farm manure treatment at present. [0003] Biogas, as the name implies, is the gas in swampy wetlands. From the perspective of scientif...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing convening and purification devices are large-scale process devices. Because they are designed for biogas plants, they have the problems of complex process flow, large floor area, and high input costs, and are not suitable for the purification of livestock and poultry manure biogas.

Moreover, since fresh livestock and poultry manure continuously enters the fermentation container of livestock and poultry manure biogas, the continuously produced biogas must have a relatively heavy odor
