The main harmful gases processed by BJS acid gas purification tower are water-soluble gases such as acid mist, hydrogen chloride, hydrogen fluoride, ammonia and alkali vapor. Sodium hydroxide was used as the absorption neutralization solution, and the purification efficiency was above 95% when the solution concentration was 2-6%. It has the advantages of high efficiency, strong corrosion resistance, high strength, low noise, low power consumption, small volume, convenient disassembly and repair, light and durable, beautiful and generous appearance.
structure
The purification tower is made up of round tower body and flange section connection. The concrete structure is composed of liquid storage tank, air inlet section, two-stage spray section, cyclone plate, air outlet cone cap, etc. Its characteristics are: easy to make, easy to install, high strength, small floor area.
Technical parameters
The working principle of
This device USES sodium hydroxide solution as absorption neutralization liquid to purify acid mist waste gas. The gas is pressed into or inhaled into the air inlet section by a centrifugal fan, and then flows upward to the filter material layer, and reacts with the neutralizing liquid ejected from the first stage nozzle. After absorption, the waste gas continues to flow upward to the second filter layer, and comes into contact with the neutralization liquid ejected from the second stage nozzle. The neutralization reaction occurs again, and then is discharged into the atmosphere by the hood, exhaust pipe or fan through the cyclone plate.
