Hygienic HRSG (cooling tower cleaning) is a dedicated cooling process that is indispensable for the production process in factories and enterprises. To better understand the cooling tower and know to clean the cooling tower effectively, let VIVABLAST give you some information.
To have an effective HRSG cleaning method and better understand this device, let’s learn about the structure and operating principle of the cooling tower. Most types of cooling towers today have a system consisting of parts corresponding to each below function:
In addition to the main parts above, the cooling tower also has several other details: windows, float valves, overflow pipes, water inlet pipes, water pipes out, engine boxes, etc.
Current cooling towers are designed in various ways, each with different cooling tower cleaning (vệ sinh tháp giải nhiệt) solutions. The following are the three basic types of cooling towers and the corresponding cleaning principles:
For a closed circulation cooling tower, there will always be a fixed amount of water in the pipeline to maintain the system. Besides, the water is constantly pressurized in this system and can remove the excess air through automatic aerators.
The problem of HRSG cleaning for closed circulation systems is not too demanding in water treatment. Instead, cleaning requires anti-corrosion and anti-bacterial solutions. Therefore, chemical treatment will be introduced from the beginning to deal with this problem. After that, the water quality will be regularly monitored and maintained to ensure the concentration is always up to the recommended standard.
Open circulation cooling towers are used quite commonly in modern industry. According to the operating principle of this type of tower, circulating water will be lost by evaporation and will be supplied continuously to compensate for the loss of water. As a result, water quality is also constantly changing.
Besides, airflow through the tower makes the water easy to absorb oxygen and dirt. Oxygen in the water is the leading cause of corrosion and dirt that accumulates over a long time and will clog the flow. At the same time, as the water evaporates, the chemicals remain and then accumulate. Therefore, in this case, HRSG cleaning is extremely necessary. Users should regularly monitor and control to quickly have a timely treatment plan.
In contrast to the above two circulating cooling towers, non-recirculating cooling towers can not reuse water. Therefore, this system will mainly use low-cost water sources such as rivers, streams, and ponds to save operating costs. However, this is the water source containing the most dirt, so it is necessary to have a suitable HRSG cleaning plan for this system.
There are many types of HRSG cleaning, and each one will have different cleaning methods. We can refer to the following process to know how to clean the cooling tower properly:
We hope this information about the HRSG cleaning and its structure in this article can help you better understand this device.
