Method/method steps to clean the condenser
1. Close the valve of the cooling water in and out of the condenser tightly, and use the thermometer tube, pressure gauge tube or sewage pipe to connect the anticorrosive pump and the liquid tank to make a small circulation system for cleaning.
2. Add pickling corrosion inhibitor first. This agent is a special copper corrosion inhibitor. It adheres to the metal sidewall of the condenser to avoid chemical reactions between acid and metal.
3. Then add a solid pickling cleaning agent to clean up calcium carbonate scale as the key component of the scale. The cleaning agent is a composite solid organic acid, white crystals, non-corrosive to metals, and a weak acid. The amount of cleaning agent used depends on the equipment. Depends on the amount of fouling.
4. Add mud scale stripping agent (optional). If the condenser equipment is thicker, you must add mud scale stripping agent to promote the reactant after the scale chemical reaction to quickly dissolve the water and accelerate the deep scale chemical reaction.
5. Add a neutralizing passivator, and after the condenser is chemically cleaned, the residual acid is neutralized to prevent the metal surface from being oxidized and converted into secondary floating rust.
It is very necessary to clean the condenser immediately on time. Considering that the condenser of the chiller is very prone to scaling, the daily water treatment should be strengthened during the summer cooling period, otherwise it will dissolve in the circulating water system when operating in a high-hardness water environment Inorganic salts in the water will crystallize out along with the rise in temperature, and scale will be produced on the tube wall of the condenser heat exchange surface, causing the efficiency of heat exchange to decrease.
