After all, the cooling tower has been placed outside for a long time, and the acceptance ability of the cooling fan is very strong, which causes a lot of sand and pollutants to be added to the inside of the tower. For a long time, the cooling effect of the cooling tower will be reduced, leading to the blockage of the drainage outlet. In order to avoid the above problems, the cooling tower should be cleaned regularly. Here, the technicians of Trlon Energy Saving Air Conditioning Equipment Co., Ltd. share with you the procedure for correctly cleaning the cooling tower:
That is, according to the cleaning process, algae cleaning, cleaning, scale remover cleaning, pre-film cleaning and cleaning up. This method must be carried out under the shutdown condition for about eight days, and the scale cleaning rate is 95% above.
Cleaning procedure: water cleaning, algae cleaning, cleaning agent scale cleaning, cleaning, cleaning, cleaning, cleaning, cleaning, cleaning, cleaning, cleaning, cleaning, cleaning, cleaning, cleaning.
1, water cleaning
The effect of water cleaning is to use a large flow of water to try to clean away the dust, sand, falling desert and corrosion and other loose dirt in the equipment, and at the same time to monitor the leakage status of the equipment. The flow rate of cleaning water should be more than 0.15m/s, and the cleaning water in the equipment should be used after qualified cleaning.
2. Algae removal
The effect of algae removal is to clean up the microbial species in the system, and make the biological soil adhered to the surface of the equipment fall off and get rid of. After the cleaning water is discharged, the equipment will be cleaned by adding algicide, and the cleaning will be stopped when the turbidity of the equipment tends to equilibrium.
3. Cleaning liquid scale cleaning
The cleaning liquid cleaning effect is to use the cleaning agent to dissolve the scale and oxide in the equipment and then dissolve in water to clean off. The cleaning agent will be added to the air conditioning system with circulation pump circulation cleaning and in the high point of the empty and low sewage, so as not to produce air resistance and drainage obstruction, harm the cleaning function. Cleaning liquid concentration, metal ion (Fe2+, Fe3+, Cu2+) concentration, temperature, pH value should be monitored regularly. When the metal ion concentration tends to be stable, the cleaning is finished.
4. Rinse after cleaning
The water cleaning is to be able to clean off the cleaning fluid and residue residue, cleaning is to keep opening the guide drenching so that the residue and residual liquid deposited in the short tube is cleaned off. Cleaning is to constantly test the pH value and turbidity. When the pH value and turbidity tend to be stable, the cleaning is finished.
The maintenance method of cooling tower is divided into the following three steps:
1, the lubrication oil for cooling tower rotational parts selection, at present, 90% of the cooling tower manufacturers in China didn't mention specific guidance on cooling lubrication, only simple show that "add oil" "grease" this kind of show that don't know, cooling tower rotational parts long running in high moisture, high temperature (especially some hot tower) environment, If the selection is not reasonable, lubricating grease is very easy to oxidation, emulsification and other factors do not work, lubrication does not work at any time to cause transmission system damage, the main performance is: belt shaking, damage; Reducer gear damage; Tower body shaking; Motor damage, etc.
2. Packing replacement, poor packing stiffness, poor load-bearing capacity, very easy to deformation, loose lodging, cooling tower manufacturers cause poor cooling effect or lack of cooling capacity at any time, if this kind of problem occurs, it is not careful, the next time to change the packing must be strictly tested.
3. Install automatic lubrication system for the part that needs to be lubricated, especially for some high temperature towers or large and medium-sized towers.
4. Corrosion treatment of cooling tower pipe fittings, because of the water quality and the product quality of some manufacturers, many metal structures of cooling towers rust in a short period of time, greatly shorten their service life, if not treated in time, there is no doubt that they will be scrapped early.
The above is the operation procedure and maintenance method of industrial cooling tower cleaning introduced by the professional technicians of Trlon Energy Saving Air Conditioning Equipment Co., Ltd. If you have these requirements, please consult us or call us directly for consultation.
