High-efficient Washing Tower (HWT)
High-efficient Washing Tower (HWT)
Working Principle of HWT
The washing tower is also called the spray tower. The main operation mode of the washing tower is that the exhaust gas is introduced into the purification tower by the air duct and passes through the packing layer, the exhaust gas and the absorption liquid are fully in contact and take absorption and neutralization reaction, as a result, the acid mist, organic waste gas and VOCs are purified, and then dehydrated and defogged by the defogging plates and discharged into the atmosphere by the fan. The absorbent liquid is pressurized by a pump at the bottom of the tower and sprayed down at the top of the tower, and then returned to the bottom of the tower for recycling. The purified exhaust gas meets the emission requirements of local emission standards and is lower than the national emission standards.
Structural Composition
The structural composition of the washing tower is diverse, and it can be divided into single tower and double tower according to the project application site, as well as vertical washing tower and horizontal washing tower. It is segmented connected by flanges. Specifically, it is composed of a liquid storage tank, a tower body, an air inlet section, a spray layer, a packing layer, a swirl defogging layer, an air outlet cone cap, and an observation window.
The material of the washing tower body is commonly used in carbon steel, stainless steel, PP, FRP or FRP and other materials. PP and FRP are often used in chemical absorption towers, which have the characteristics of acid resistance, alkali resistance and corrosion resistance, and stainless steel materials can be used for high-temperature exhaust gas. The filler can be Pall ring, Lassi ring, etc., and the filler materials can be PP, plastic, ceramic, 304 stainless steel and other materials. The mist eliminator includes swirl plate mist eliminator, or wire mesh mist eliminator, etc.
Scope of Application
washing towers are widely used in food, chemical, plastic, electronics, automotive spraying and coating, mold, wood, metallurgy, machinery, petroleum, power plants, solar energy, alloy grinding and other industries.
1) Treatment of harmful gases such as H2S, SOx, NOx, HCI, NH3, Cl2, H2SO4, VOCs and other gases such as dust, VOCs, inorganic acid and alkaline exhaust gases, organic exhaust gases, etc.;
2) Deodorization devices for garbage transfer sites, physical treatment, garbage incineration, and sewage treatment sites;
3) Process exhaust treatment in the semiconductor optoelectronics industry;
4) Waste gas treatment of seepage water storage tank in landfill;
5) Treatment of exhaust gas emitted from incinerators and industrial furnaces.
