Exhaust gas treatment equipment

Causes of blockage of exhaust gas treatment equipment

1. Index control of desulfurization system of flue gas treatment equipment.

2. When the temperature is low, the waste gas treatment device is heated in liquid phase.

3. The selection of internal components of chemical waste gas treatment equipment is wrong.

4. Not selecting an appropriate desulfurizer. 

5. The regeneration effect of desulfurization liquid is not good, and the sulfur content in the lean liquid is high. The recovered flue gas was poorly treated, the sodium bisulfate Na2CO3 in the flue gas absorbed hydrogen sulfide instead of total oxidation element sulfur, and the flotation foam was collected, and the chemical flue gas treatment equipment was introduced, which was completed on the flue gas treatment tower The oxidation reaction produces elemental sulfur, which is then attached to the surface of the package, which forms a section of the wall of the chemical flue gas treatment tower equipment.

6. The recovery quality of sulfur: The recovery quality of sulfur directly reflects the desulfurization amount of sulfur. Even if the desulfurization system operates normally and the sulfur does not come out, it will inevitably get stuck in the tower, which will bring hidden danger to the blockage of the tower. Refluxing molten sulfur into the system is an important cause of excessive secondary salt content.

7. Dust removal effect in the front section: As we all know, the gas entering the desulfurization system has complex composition and contains a large amount of impurities and dirt. Once inside the chemical exhaust treatment device, it is very difficult to remove.
