An organic waste gas treatment system with good anti-corrosion effect

Abstract

The invention discloses a system for treating organic waste gas with good anticorrosion effect, which comprises an oxidation furnace. The air inlet of the oxidation furnace is connected with a waste gas path, and the gas outlet is connected with a clean gas path. There are pre-alkaline washing device and water washing device, and the clean gas path is equipped with a quenching device, a post-alkaline cleaning device and a rear fan in sequence along the direction of clean gas transportation. The present invention has beneficial effects: remove the original acidic substances in the waste gas through the pre-deacidification device, thereby reducing the probability of corrosion of the post-process equipment, and remove the acidic substances produced by incineration through the post-deacidification device, thereby further reducing the post-process equipment The probability of being corroded, and the anti-corrosion coating in the oxidation furnace can avoid dew point corrosion caused by acidic substances during precipitation, reduce the load on the subsequent process equipment, and ensure the stable operation of the system.

Description

technical field [0001] The invention belongs to the technical field of industrial tail gas treatment, and in particular relates to an organic waste gas treatment system with good anticorrosion effect. Background technique [0002] Many industrial production lines will produce a large amount of organic waste gas, according to the requirements of national laws and regulations, these organic waste gases must be purified before they can be discharged. [0003] Thermal oxidation technology is a common purification technology at present. Compared with previous purification technologies, thermal oxidation technology has higher treatment efficiency. In the prior art, the general process of thermal oxidation technology is: the production fan sends the organic waste gas from the production line to the thermal oxidation device, and the organic waste gas fully reacts in the oxidation device, and after sufficient heat exchange, it is discharged to the chimney. [0004] The process of th...
