How do we solve the partial corrosion phenomenon of exhaust gas treatment equipment:
The use of exhaust gas treatment equipment in the chemical industry is becoming more and more frequent, and it has become an indispensable device in the production process. However, in the production, due to some corrosion of the exhaust gas treatment equipment, the weld of the tube sheet leaks, resulting in the mixing of water and chemical materials, the production process temperature is difficult to control, resulting in the production of other products, which seriously affects the product quality and reduces Product grade.
First, because some parts of the exhaust gas treatment equipment are often exposed to the surface of the medium, it is easy to produce uniform corrosion;
Second, when the exhaust gas treatment equipment is working, because the potentials are different, when two metals come into contact, when passing through the electrolyte solution, a current will flow between the two metals, which will easily cause corrosion, especially the potential. The corrosion rate of negative metals will also increase;
Third, the exhaust gas solution formed by cooling will also cause some corrosion to the metal.
Fourth, sometimes the exhaust gas treatment equipment will also intensify the corrosion of the metal during heat transfer.
