The closed cooling tower uses the circulating water system to remove heat. The volatilization of the cooling circulating water in the fan coil not only removes heat, but on the other hand, it also causes the increase of the concentration of impurities in the water and the proliferation of a large number of microorganisms. The increase of debris and the proliferation of microbial strains will increase the scale on the surface of the fan coil, and increase the coverage of the baffle and the galvanized sheet surface, which will lead to slow heat removal and reduced cooling efficiency, which will corrode the cooling tower equipment and reduce The service life of the cooling tower.
The closed structure of the closed cooling tower is the main cause of fouling inside. The repetitive operation water of the closed cooling tower exchanges heat with the atmosphere and spray water in the curved copper tube array. The long-term closed circuit repetition causes the impurities in the water to be unable to be discharged, and the reduction of water volume accelerates the increase of the impurity concentration. In the process, high temperature conditions produce a large number of microorganisms. The emergence and development of this kind of root-cause problems will inevitably cause scale in the copper pipes, and even weak acid components, which erode the pipes and waterways.
The alloy material of the closed cooling tower is eroded due to atmospheric intrusion during the shutdown period of the facility; during the operation period of the cooling tower, the dissolved substances in the water will cause corrosion to the metal. This kind of corrosion fouling caused serious damage to the outer wall and inner parts of the cooling tower, and endangered the life of the cooling tower.
The copper pipes of the closed cooling tower can be exchanged with the atmosphere and water at the same time when the copper pipes of the closed cooling tower are clean. The heat dissipation effect is very good and the cooling efficiency is high. If there is dirt inside and outside the copper pipe, the heat will pass through the dirt and then be transmitted to the atmosphere and water. The heat transfer efficiency of the dirt is very low. The appearance of flakes of dirt will seriously harm the heat rejection performance of the cooling tower and cause the cooling tower. Can not achieve the effect of heat removal and cooling.
Trlon closed cooling tower is equipped with a supplementary storage tank system and automatic dosing facilities, which can automatically realize the scale cleaning work content of the closed cooling tower.
1. The replenishment water tank system spares repetitive operation water, and automatically realizes the replenishment of volatile water. The volatilization of the circulating water in the trlon closed cooling tower will induce the operation of the supplementary storage tank equipment, and the supplementary storage tank's water source is the same type of operating liquid as the internal circulating operating water. The new water source supplement keeps the circulating working water in the cooling tower always at a moderate amount, and will not increase the concentration of impurities in the inner circulation, thereby avoiding the root cause of fouling and solving the problem caused by the fouling of the inner tube from the source.
2. Fully automatic dosing facilities operate automatically to eliminate internal circulation erosion and microorganisms. The trlon closed cooling tower is equipped with a fully automatic dosing facility in the internal circulation system. The medicament in the fully automatic dosing facility will be filled into the internal circulation operation water in a timely manner, and the medicament injected into the repeated operation liquid will cause leaching in the pipe Corrosion components metal oxides and metal salts cause decomposition and effectively clean up the erosion of the corrosion components. In addition, the working liquid of the filled medicament can effectively decompose the dirt that has been generated in the pipe and has the function of inhibiting and killing microorganisms.
3. Manually add cleaning agents to properly handle emergencies. The trlon closed cooling tower is the same as other closed cooling towers. It can be manually equipped with dilute hydrochloric acid to clean the scale. In the process of cleaning the scale and configuring dilute hydrochloric acid in a closed cooling tower, calculations must be carried out based on calculation formulas, which cannot be used based on experience. Excessive hydrochloric acid concentration will cause corrosion of copper pipes and steel pipes. In the process of use, it is necessary to configure anti-corrosion gloves and other protective equipment, and run for a period of time after cleaning is achieved before putting it into industrial use. After the clean-up is achieved, the integrity of the facilities must be tested to ensure that the facilities are safe and reliable before use.
