Reasons for descaling and scaling of evaporators

The traditional cleaning method generally uses chemical properties - pickling passivation, which is reasonable for a variety of accumulations and saves time and effort than mechanical equipment. However, chemicals corrode the system and other metal material components, which is very easy to erode the pipes of machinery and equipment, and have an impact on the environment when sewage is emitted.

Scale cleaning preparation in advance

1. Cut off the system unrelated to the evaporator.

2, open the evaporator water side higher vent valve and steam side bottom point guide valve to ensure that a lot of steam caused in the whole process of cleaning can immediately blow down and clean the filling degree of liquid; The leakage condition of the heat exchanger air conditioning copper pipe in the cleaning process is detected according to the shower valve.

3, in order to detect the actual cleaning effect of the system and the erosion condition of the machine and equipment during the cleaning process, before the cleaning project construction, the standard etching test pieces of the machine and equipment materials and the detection pipeline are respectively suspended in the cleaning tank.
