AI Technical Summary

Technical Problem

When using existing absorption methods to treat waste gas from the regeneration of waste coal tar, the absorbent is prone to saturation and insufficient contact with the waste gas, resulting in low treatment efficiency and excessively high humidity in the waste gas, which may clog the adsorption equipment and affect the stability and continuity of the treatment process.

Method used

A cyclone separator is used for initial gas-solid separation. A circulating pump and spray head are used to ensure that the absorbent liquid and the waste gas are in full contact. The spiral baffle and conical guide plate are combined to achieve full mixing and separation of the waste gas and the absorbent liquid. A demisting component is used to remove water droplets from the waste gas to ensure the recycling of the absorbent liquid.

Benefits of technology

It improves the recovery efficiency of organic solvents, reduces the content of organic solvents in waste gas, achieves effective resource recovery and waste gas purification, avoids equipment corrosion and blockage, and ensures the stability of the treatment process.
