Method and device for efficiently recovering VOC gas

Abstract

The invention discloses a method and a device for efficiently recovering VOC gas. The device comprises a base, a first purification assembly is arranged on the left side of the top of the base, a gasinlet pipe is connected to the left side of the first purification assembly, a gas inlet hopper is detachably and fixedly connected to the gas inlet pipe, and a second purification assembly is arranged on the top of the base; the second purification assembly is connected with the first purification assembly through a connecting pipe, an adjusting push handle is arranged on the right side of the top of the base, and a damping moving assembly is arranged at the bottom of the base; VOC gas is purified through the first purification assembly, most of the VOC gas can be removed, the gas purified through the first purification assembly enters the second purification assembly, the VOC gas is purified again through the second purification assembly, the purification effect is achieved, operation isquite simple, the VOC gas recycling cost is low, meanwhile, the damping moving assembly is arranged, when the device moves, a damping effect can be achieved, and the height of the push rod is adjusted by the adjusting push handle.

Description

technical field [0001] The invention relates to the technical field of VOC gas treatment, in particular to a method and device for efficiently recovering VOC gas. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compound, referred to as VOC) usually refer to organic compounds with a vapor pressure > 70.91Pa at room temperature and a boiling point below 260 degrees Celsius in the air, generally including alkanes, alkenes, alkynes, aromatics, ketones, alcohols , ethers, esters, etc., and some organic compounds containing N, O, s, halogens and other substitution atoms. VOCs are ubiquitous in biogas or landfill gas, etc., running gas chromatography and spectroscopy (GC-MS) and other detection methods, found VOC substances It can be as high as hundreds of kinds, and common VOCs include benzene, toluene, xylene, pinene, etc. In the process of gas purification such as biogas or landfill gas, including the main processes such as the use of gas separation...

AI Technical Summary

Problems solved by technology

The recovery effect of the existing VOC gas recovery devices is relatively general, and at the same time, the operation is relatively complicated, the procedures are cumbersome, and the recovery cost is high, which brings great inconvenience to the user, and the existing device structure is complex and not easy to move. limited the scope of its use
