In the manufacturing industry, periodic cleaning of cooling towers is essential in the HRSG cleaning process. This step helps to limit the problems of blockage and system rust. It ensures the system is always in a stable operating state, and the overall performance of the tower is not affected. So how is the tower cleaning process done?
Cooling towers are widely used in refrigeration, seafood, metallurgy, and pharmaceutical industries… with the role of reducing the temperature of the water stream by extracting heat from the water and releasing it into the atmosphere. Cooling tower cleaning is an important part of the HRSG cleaning process. For the cooling tower to operate normally, regular cleaning and maintenance should be carried out to prevent the growth of microorganisms and dirt.
To conduct HRSG cleaning and effective cooling tower cleaning, you should understand the tower’s structure. Cooling towers are made up of different components that work together to ensure the efficiency and functionality of the entire system. These components will wear out over time and require servicing or retrofitting throughout the tower’s life. Cooling tower cleaning is usually done periodically with specialized equipment and techniques. The main parts of a cooling tower and their functions include:
In addition, the tower also has other parts that can be mentioned, such as the air inlet port, the gearbox, the engine, and the reducer box… There are also many particular types of towers made up of various enhancements.
Cooling tower cleaning is an integral part of the HRSG cleaning process. Because after a period of operation, the tower accumulates dirt and has the invasion of microorganisms that cause corrosion processes. Businesses should have a maintenance plan, including cleaning the cooling tower, if you want the tower to function properly. Not only that, but the tower cleaning also plays many other important roles such as:
Cleaning and treating the water in the cooling tower doesn’t just keep the system clean; it also prevents corrosion and scale formation as well as microbial growth. Thereby reducing costs incurred and increasing the efficiency of the whole system.
Regular cooling tower cleaning (vệ sinh tháp giải nhiệt) and water treatment are part of an overall maintenance plan for the HRSG cleaning process. The steps in this cleaning process will make the system more durable, perform better, and help reduce negative impacts on the environment and worker health.
We need to maintain a certain amount of water in the tower used to dissolve cleaning chemicals in this step. It is necessary to choose a specialized solution with an appropriate concentration and degree of cleaning so as not to affect the durability of the tower and ensure the safety of workers.
After pouring chemicals into the tower, they will open the valves and pipes and turn on the pump to let the chemicals go through the system to perform the cleaning task, cleaning the accumulated dirt.
Depending on the size and time of cleaning the cooling tower, the circulation will begin to discharge the chemicals in the tower after a certain period. Operators must neutralize chemicals before removing them from the system to not adversely affect the environment. Continue to refill and repeat the sterilization process and then drain all chemicals in the pipeline. Use purple litmus to measure pH; if the pH of the rinse water is neutral, it means the rinse water has met the standard.
Using chemicals to kill algae in both the vents and nozzles to remove dirt and bacteria prevents fungi and moss growth and development in the tower effectively. This chemical mixture creates a thin film that protects the surface of the parts from the adhesion and rooting of microorganisms. In addition, the technician performing the cleaning can also use a UV light for this step to kill bacteria in the tower system.
When cleaning the cooling tower in the water distribution pipes, technicians follow the following steps: disassemble, spray, and clean dust and moss on the radiator panels and distribution pipes. Once completed, proceed to assemble the system as before.
Other parts of the cooling tower system also need to be cleaned, such as the tower body, tower shell, propellers, mesh panels… The tower’s surfaces can also contain bacteria on the surface from the cooling water or from ozone. Clean all surfaces and sinks, and disinfect any surface that comes in contact with water. After disassembling for cleaning, it is necessary to check for any damaged parts to make repairs or replacements if necessary before proceeding. This ensures all system components are in top condition, increasing the life and efficiency of the tower.
It can be seen that, whether the system is small or large, cleaning the cooling tower is a necessary option for the HRSG cleaning process. It brings great benefits in terms of cost and time and keeps the system stable, durable, and good working order. However, to ensure effective and trouble-free cleaning, choosing a quality tower cleaning service provider is a matter of careful consideration.
