Waste Gas Purification Tower for Industrial Acid Exhaust Gas Treatment
Introduction:Industrial acid flue gas purification is a core requirement for chemical, electroplating and pharmaceutical factories to meet environmental discharge standards. The waste gas purification tower is a mainstream wet scrubbing device, which can cooperate with Dust Collector Filter and Air compressor filter to build a complete gas treatment system. It absorbs and neutralizes acidic pollutants inside the tower, widely used to treat sulfur oxides, nitrogen oxides and various acid tail gas.

Product Introduction
Our waste gas purification tower is a countercurrent packed scrubber for industrial waste gas purification. Matched with Dust Collector Filter, Air compressor filter and other supporting filter elements, it forms a complete pre-treatment and deep purification solution. This equipment separates pollutants from gas and converts them into harmless substances through gas-liquid contact reaction. It adopts micro-mixing counterflow structure, and the tower body can be customized with FRP, PP, PVC materials according to corrosive working conditions. The high-efficiency pall ring packing provides sufficient reaction surface, with low pressure drop, flexible operation and strong ability to remove multiple pollutants at the same time.
Working Principle
The waste gas purification tower realizes pollutant removal by mass transfer between gas and liquid. Contaminated gas enters the tower and flows upward in countercurrent direction, while the scrubbing liquid is sprayed down from the top of the tower in mist or droplet form. When the gas passes through the packing layer, a liquid film forms on the packing surface. Harmful substances in the gas are absorbed and neutralized after contacting with the liquid film. After the reaction, the cleaned gas passes through the demister to remove entrained water droplets, and then is discharged out of the tower through the air outlet. The circulating liquid is filtered by the circulating filter screen and recycled by the circulating water pump.

Installation & Maintenance
Keep the air duct connection sealed to avoid air leakage, and the circulating liquid pipeline should be checked regularly for blockage.
Clean the circulating filter screen periodically to prevent packing blockage caused by impurities.
Inspect the packing layer and demister regularly, replace damaged packing in time.
Equip with Dust Collector Filter and Air compressor filter for pre-treatment to reduce dust entering the tower and extend service life.
FAQs
Q1: What kinds of waste gas can this purification tower handle?
A: It is mainly used for acidic waste gas such as sulfuric acid, nitric acid, hydrochloric acid tail gas, SOx, NOx and some organic waste gas from electroplating and chemical workshops.
Q2: Can the tower material be customized?
A: Yes. FRP, PP or PVC are available for selection according to the acidity and corrosivity of the waste gas.
Q3: What is the function of the demister inside the tower?
A: It removes water mist carried by purified gas, preventing water droplet escape and secondary pollution.
Q4: Is this scrubber suitable for intermittent production lines?
A: Yes, it supports both continuous and intermittent waste gas treatment conditions.
Q5: Do we need pre-filter equipment before the tower?
A: Yes. Dust Collector Filter and Air compressor filter are recommended as pre-treatment units to intercept dust and protect the internal packing.
