Chemical desulfurizer defoaming solution

Customer type

1. Customer information: Jinhui Chemical is a chemical distributor. Among his customers, there is a thermal power plant. Because the desulfurizer foam cannot be solved, I found us on the Internet, hoping to give a solution

2. Sample information: desulfurization and defoaming agent

3. Customer requirements: fast defoaming speed and long foam suppression time.

Principle and analysis of defoaming

1. Analysis of the cause of blistering

When the flue gas is washed by the limestone slurry in the absorption tower of the wet desulfurization system, a large amount of foam is produced.

2. The hazards of blistering

① Ash accumulation at the entrance of the bubble absorption tower.

②The liquid level in the tower is falsely high and the slurry overflows

3. Recommended for defoaming with defoamer

The power plant desulfurization defoamer is specially developed for the flue gas desulfurization slurry foaming system. It has transparency, good capacity, long-term defoaming and foam suppression performance, so as to control the liquid level in the tower, eliminate the false high liquid level caused by foam, and prevent The slurry overflows to alleviate the problem of fouling and clogging of the heat exchanger (GGH) caused by foam.

4. Product features

Tests should be carried out to determine applicability before use;

Stir gently before use;

Calculation of dosing amount: Generally, the addition amount of defoamer is 1～5‰, and the final usage amount is based on actual experiment. Under normal operation, the slurry amount is the standard. This product should be dosed in a one-off impact mode for the first time, and then added once every 24 hours. However, the actual dosage is determined by the composition of the foaming liquid, the amount of flue gas, the composition of coal, and the combustion process. Conditions, absorbents, and sulfur dioxide content. The user can finally determine the dosage according to the actual situation.

In the process of continuous addition, the pump can be used to calculate the addition, and it can be added at one time in the batch process.
