AI Technical Summary

Technical Problem

In existing spray tower pretreatment devices, the lower packing material is easily adhered to by dust particles and oil stains, resulting in a reduction in the gas-liquid contact area, which affects the treatment effect and increases the frequency of packing material replacement.

Method used

A second nozzle is installed inside the inlet pipe to generate water mist to capture dust particles. The inlet pipe is inclined and protected by a baffle plate. A third nozzle is installed inside the housing to flush the bottom layer of packing material. The housing is divided into two working areas to facilitate sewage discharge.

Benefits of technology

Reduce contaminant adhesion to the packing layer, extend the packing replacement cycle, improve gas-liquid contact efficiency, and reduce the risk of blockage.
