Why do power plants need to use power plant desulfurization defoamer for desulfurization
Thermal power plants use power plant desulfurization technology, in the process of desulfurization will produce a large amount of carbon monoxide and carbon dioxide, in the container to produce foam, foam production affects the progress of work, emission pollution of the air environment. At this time, timely selection of appropriate defoamer can reduce the waste of raw materials; reduce the cost of desulfurization; increase the service life of the machine.
We all know that conditions are needed to produce foam, briefly explain the necessary conditions for foam production :
1. Foam can be produced only when the gas is in continuous and full contact with the liquid;
2. When the difference in density between the gas and the liquid is very large, the foam in the liquid can be made to rise to the surface very quickly, and the foam is formed;
3. the smaller the surface tension the easier it is for the liquid to foam.
Then during the operation of the desulfurization unit, all of these conditions can cause the generation of bubbles:
1. the imported flue gas dust exceeds the standard, if it contains a lot of inert material
2. bad coal quality, insufficient boiler combustion or boiler oil injection so that the imported flue gas contains oil.
3. limestone containing excessive MgO, excessive MgO not only affects the efficiency of desulfurization and will react with sulfate ions.
4. Heavy metal ions in the absorber slurry increase the surface tension of the slurry.
5. In addition, we should also pay attention to the desulfurization system process water quality parameter indicators to be within the design range, otherwise it will also lead to the absorption tower slurry bubbles.
Power plant desulfurization defoamer is based on organosilicon complex, can prevent, control agent to eliminate foam in the aqueous system.RISE power plant desulfurization antifoam has the advantages of: aqueous medium easy to dispersed acid and alkali resistance as well as the use of a wide range of temperatures, antifoam agent antifoam quickly, foam suppression time is long, room temperature and high temperature antifoam, foam suppression is good, and desulfurization antifoam agent can eliminate the small bubbles.
