AI Technical Summary

Technical Problem

In existing technologies, coke oven flue gas still has a high temperature and contains recyclable impurities after filtration. Direct emission of such gas results in resource waste, and the filtration device is prone to clogging. The cleaning process is cumbersome and the downtime is long, which affects production efficiency.

Method used

Design a coke oven flue gas dust removal and recovery device, which includes an electrostatic precipitator and a filter dust removal device. Impurities are easily separated, the filter screen is removable and replaceable, the hopper collects impurities, and the ejector recovers flue gas. The structure is simple and easy to clean.

Benefits of technology

It achieves effective filtration and recycling of flue gas, reduces resource waste, simplifies the cleaning process, and improves production efficiency and equipment utilization.
