Abstract

The invention discloses a cleaning spraying tube. The cleaning spraying tube comprises a steel tube, wherein a through hole is formed in the steel tube; one end of the steel tube is welded, and the other end of the steel tube is equipped with a sleeve; the other end of the sleeve is equipped with a control ball valve; and the two ends of the sleeve are equipped with outer wire buckles with diameters being DN25. The invention further discloses a mist catcher online cleaning method based on the cleaning spraying tube. According to the cleaning spraying tube and the cleaning method, the cleaningoperation is simple, the period is short, complex processes such as desulfurizing tower halt production, mist catcher dismounting, cleaning and re-fitting are simplified, manpower and material resources are saved, production is not affected by cleaning, working efficiency is improved, equipment corrosion and industrial pollution of fuel gas system cleaning are reduced, and safety is high.

Description

technical field [0001] The invention relates to the technical field of desulfurization tower cleaning, in particular to an online cleaning method for a mist catcher. Background technique [0002] In the coking industry, the HPF method is often used for gas desulfurization. In order to prevent impurities such as desulfurization liquid and tar in the gas from being carried into the next process, a swirl plate mist catcher is installed on the gas outlet pipe of the desulfurization tower to capture the desulfurization liquid in the gas. , tar and other mist droplets flow to the desulfurization tower through the downcomer of the mist catcher. After the desulfurization tower runs for a cycle (6-12 months), due to the poor quality of the desulfurization liquid or the high content of impurities such as desulfurization liquid and tar in the gas, the mist will adhere to the swirl plate, and the deposits will accumulate more and more Too much, resulting in increased resistance of the ...
