The stainless steel mixing tank needs to be chemically cleaned after a period of use. The specific cleaning method and process will be introduced in detail below.
1. Reasons for chemical cleaning
In the process of installation, welding and production of stainless steel mixing tank, there are dust, welding slag, grease, rust, etc. on the inner surface of the steel. The existence of these dirt will pollute the product and affect the chemical and physical quality of the storage medium, so chemical cleaning is required. , meets the required cleanliness.
2. Cleaning method
1. Spray cleaning is a cyclic cleaning technology. During the cleaning process, the chemical cleaning solution is evenly sprayed on the inner surface of the system to be cleaned, and flows along the wall of the container to the bottom with the help of the gravity of the cleaning solution. The rust and scale on the inner wall come into contact, and the chemical reaction occurs, which meets the requirements of the cleaning system. By adjusting the position of the spray head, the cleaning liquid can be sprayed to the top and wall of the tank to maintain the cleanliness of the entire inner surface.
2. In spray cleaning, the design of the sprayer is more important. Improper design or selection of the sprayer will lead to uneven distribution of the cleaning liquid, which will directly affect the cleaning effect. Commonly used sprinkler heads are rotary sprinkler heads. A rotating nozzle is installed on the cleaned stainless steel mixing tank, and the nozzle is driven by hydraulic torque to make the nozzle rotate.
3. Cleaning process
Water flushing and system pressure test → degreasing → water flushing → pickling (passivation) → water flushing → manual treatment → drying.
