Causes of cylinder corrosion of chemical sludge drying equipment

Chemical sludge drying equipment is a green, energy-saving and environmental protection equipment specialized in the treatment of petrochemical sludge. It is also a common type of equipment at present. In the process of using chemical sludge drying equipment for a long time in chemical enterprises, the cylinder of the equipment will have different degrees of corrosion, which will seriously affect the long-term durability of the equipment and shorten the service life of the equipment. The causes of cylinder corrosion of chemical sludge drying equipment are as follows:

1. Due to the high temperature in the sludge drying process, it is inevitable to transfer heat to the sludge in the process of drying It is corroded to a certain extent. Therefore, some characteristics of sludge are one of the reasons for corrosion of equipment barrel. Therefore, in view of this situation, users can choose the equipment with low-temperature drying process when selecting chemical sludge drying equipment.

2. When users use the chemical sludge drying equipment to dry the sludge, the temperature and humidity of the hot flue gas inside the cylinder fluctuate greatly, which may cause condensation inside the cylinder. In addition, the gas evaporated from the sludge contains corrosivity. If the humidity of the hot gas is high, the droplets will condense on the metal components, which will cause the equipment to damage The cylinder causes corrosion.

3. Some users install the chemical sludge drying equipment in the open air. It can be imagined that in such a long-term sun and rain environment, the paint coating on the surface of the equipment will inevitably fall off, resulting in equipment corrosion. If the peeling layer cannot be repaired in time, it may cause a wider range of corrosion.

In a word, there are many reasons for the cylinder corrosion of chemical sludge drying equipment, and I will not talk about it here. When users choose chemical sludge drying equipment, they should choose the appropriate equipment according to their own actual situation. In addition, users need to repair and maintain the barrel of the equipment in the process of use, which can not only prevent the damage caused by corrosion on the cylinder of the equipment, but also ensure the service life of the equipment.
