A kind of vocs processing method and device thereof

Abstract

The invention discloses a VOCs treatment method and a device thereof, and relates to the field of regeneration of activated carbon or zeolite that has adsorbed VOCs. The treatment device includes a VOCs gas treatment interface connected to an adsorption tower, a treatment gas pipeline, a catalytic combustion reactor, a purification Pipeline, induced draft fan, flue gas regulating valve, mixer, clean flue gas interface for connecting with the adsorption tower and providing clean flue gas for the adsorption tower, liquefied gas storage device, gas burner, air intake for connecting with the atmosphere Ducts, clean flue gas discharge ducts, blowers for feeding air into the clean ducts. By adjusting the technological process, the inventor solved the contradiction between the high pressure of the gas combustion chamber and the low pressure of the combustion fan of the gas burner under the premise of realizing the normal operation of the catalytic combustion reactor and the gas burner. At the same time, under the premise of changing the process flow, through the innovation of the structure, the secondary impact brought by the overheated air flow is solved, and the stable, reliable and efficient operation of the device is guaranteed.

Description

technical field [0001] The invention relates to the field of VOCs gas treatment, especially the field of regeneration of activated carbon or zeolite that has adsorbed VOCs, and specifically relates to a VOCs treatment method and a device thereof. This application is based on the existing vehicle-mounted VOCs processing device, and through the improvement of the processing flow, the equipment requirements are effectively reduced, which is conducive to reducing the processing cost, and has high application value. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compounds), referred to as VOCs, refers to organic compounds with a saturated vapor pressure greater than 70 Pa at room temperature and a boiling point below 260 °C at normal pressure, or at 20 °C with a vapor pressure greater than or equal to 10 Pa and All organic compounds that are volatile. In recent years, with the rapid development of industry, various types of pollution have become incre...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem of regeneration of activated carbon that adsorbs VOCs, the applicant first disclosed a vehicle-mounted VOCs regeneration device with a publication number of CN208066067U. The activated carbon adsorption device, when the activated carbon is saturated, is usually replaced or discarded directly, which does not meet the requirements of environmental protection and energy saving and emission reduction.
