Problems solved by technology

[0003] Generally speaking, for the pollution sources that produce VOCs gas, they have the characteristics of large flow rate and unstable concentration. It is not economical to use the recovery method. Therefore, at present, the combination of adsorption method and destructive method is often used for purification treatment, but this increases virtually. The complexity of the entire purification device system increases investment and operating costs, and also puts forward certain requirements for the corresponding operation and control system

Abstract

The invention relates to the technical field of purification equipment, and particularly relates to a use method of a device for combined purification of organic waste gas. The device for combined purification of organic waste gas, provided by the invention, can determine a method for finally removing the organic waste gas according to the concentration of the organic waste gas; when the concentration of the organic waste gas is large, a combustion method is adopted; and when the concentration of the organic waste gas is small, an absorption tower is adopted for absorption. The device for combined purification of organic waste gas is low in energy consumption, can not cause secondary pollution, and has relatively high stability. In addition, the device for combined purification of organic waste gas is reasonable in structural design, convenient and fast in use and maintenance, and suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of purification equipment, in particular to a method for using a combined device for purifying organic waste gas. Background technique [0002] In my country, VOCs (volatile organic compounds) refer to organic compounds with a saturated vapor pressure greater than 70 Pa at normal temperature and a boiling point below 260 °C at normal pressure, or with a vapor pressure greater than or equal to 10 Pa at 20 °C. The corresponding volatile total organic compounds [0003] Generally speaking, for the pollution sources that produce VOCs gas, they have the characteristics of large flow rate and unstable concentration, and it is not economical to use the recovery method. The complexity of the entire purification device system increases investment and operating costs, and also puts forward certain requirements for the corresponding operation and control system. How to quickly purify a large amount of organic waste ga...
