EXN-903 Defoamer Special for Desulfurization System

Properties and uses

In the flue gas desulfurization absorption tower, due to the high-speed reverse mixing of gas and liquid, and when the flue gas contains a large amount of dust, it will cause the continuous generation of a large amount of foam, causing a large amount of neutralizing material and the loss of cooling water while also significantly reducing the reaction Speed and product recovery. At the same time, a large amount offoam overflow also brings significant safety risks and power loss to the motor room below the cooling tower. In the desulfurization tower, the addition of defoamers can effectively improve the application efficiency of cooling water and absorbents, significantly reduce the frequency and number of circulating water pumps, greatly increase the output of sulfate and other products, and at the same time reduce the site The cost of manual maintenance, thereby improving comprehensive benefits.

Package and Storage

25kg net Plastic Drum, IBC tank can also be used as required.Storage for 12 months in room shady and dry place.

Safety Protection

Avoid contact with eye and skin, once contacted, flush with water

Specification

1. In the pit of process supply water;
2. Adopt intermittent periodic impact dosing or metering pump continuous dosing;
3. Dosing amount: when the absorption tower initially foams and overflows, a larger amount needs to be added, and the subsequent dosage should be based on the composition of the foaming agent, the amount of flue gas, the quality of coal, the combustion process, and the absorbent ,Depends on the amount of sulfur dioxide, the unit of use can finally determine the additive according to the actual situation (recommended recommended dosage of 20ppm-50ppm);
4. Dosing frequency: generally twice a day, the specific dosing frequency depends on the foaming of the absorption tower.
