Condenser cleaning

(Close the valve of the cooling water in and out of the condenser, use a thermometer tube, pressure gauge tube or sewage pipe to connect the anti-corrosion pump distribution tank to form a small circulation system for circulation cleaning.
(First add the pickling corrosion inhibitor. This agent is a special copper The corrosion inhibitor adheres to the metal inner wall of the condenser to prevent the acid from reacting with the metal.
(A solid pickling cleaning agent is added to clean calcium carbonate scale. The scale cleaning agent is a compound solid organic acid white crystal that is mainly composed of calcium carbonate. The non-corrosive nature of metal is weak acid. The dosage of cleaning agent depends on the amount of scale on the equipment.
(Add scale stripper (optional)) If the scale on the condenser equipment is thick, you need to add scale stripper to promote the scale reaction. The product quickly dissolves in water to accelerate the deep scale reaction
(Add a neutralizing passivating agent and chemically clean the condenser to neutralize the residual acid to prevent the metal surface from oxidizing and generating secondary floating rust.
(Cleaning process
(Cleaning temperature: Normal cleaning is generally performed at room temperature. If the scale is thick, it can be cleaned at ℃ ~ ℃ to increase the cleaning speed.
(Close the valve in and out of the unit, use a pressure gauge or thermometer to pipe anti-corrosion pump acid tank Connected to form a cleaning circulation system. When cleaning, add corrosion inhibitor first, and then slowly add organic acid after the corrosion inhibitor circulates evenly. During cleaning, the reaction should be checked regularly. When the cleaning agent is insufficient, it needs to be replenished to ensure that there is enough acid and scale to react. Press the scale during cleaning. According to the reaction situation, an appropriate amount of dirt stripper, defoaming agent, etc. can be added.
(After cleaning, the remaining liquid should be drained and rinsed with clean water.
(After cleaning the condenser, a neutralizing passivating agent needs to be added to neutralize it. Residual acid to prevent oxidation of the metal inner wall.
(The condenser cleaning time is about ~ hours, depending on the actual situation
