The degree of importance of descaling work relative to closed cooling towers. The closed cooling tower is a comprehensive product integrating aerodynamics, thermodynamics, fluidics, chemistry, biochemistry, materials science, static and dynamic structural mechanics, production and processing technology and many other specialties.
The closed structure of the closed cooling tower is the main reason for the scale inside.
The cyclic reciprocating working water for descaling of closed cooling tower manufacturers realizes heat exchange with gas and spray water in the tortuous coil array. The long-term closed-circuit reciprocating makes the impurities in the water unable to be discharged, and the reduction of water flow accelerates In order to increase the impurity concentration, there are many microbial species in the high temperature environment. The occurrence and development of these fundamental problems will inevitably cause scale formation in the coil, and even produce weak acid substances, which will corrode the tube and waterways.
The metal material of the closed cooling tower is corroded by gas when the equipment is out of use; when the cooling tower is running, the dissolved substances in the water will corrode the metal. The closed cooling tower is a comprehensive product integrating aerodynamics, thermodynamics, fluidics, chemistry, biochemistry, materials science, static and dynamic structural mechanics, production and processing technology and many other specialties. The corrosive scale formed in this way has severe damaging effects on the outer wall and inner components of the cooling tower, and endangers the service life of the cooling tower.
When the descaling coil of the closed cooling tower is in a clean state, the transmitted heat can be exchanged with gas and water at the same time, which has good thermal conductivity and high cooling efficiency. If there is scale inside and outside the coil, the heat must pass through the scale and then be transferred to the gas and water. The heat transfer efficiency of the scale is very reduced. The appearance of the entire scale will obviously harm the heat conduction effect of the cooling tower and cause the cooling tower to reach Not as effective as heat conduction and cooling.
