How to reduce temperature during the production process
Thread Content
It’s too hot in summer; the temperature of the secondary water doesn’t drop, and the refrigerators are not sufficient. Many of the company’s equipment use jackets for cooling (the material is in the reactor, while secondary water flows through the jacket); the temperature drops very slowly. I’d like to hear everyone’s ideas on this.
It can discharge directly and clean the jacket; the poor cooling effect is due not only to a small temperature difference but also to the high water temperature in summer, which leads to an increase in microorganisms and thus a reduction in the heat transfer coefficient.
Is the cold insulation of the pipeline for transporting chilled water good? If not, it needs to be replaced. This way, there is less loss of cooling capacity in summer, cooling occurs more quickly, and energy is saved as well
Since it is conveyed through a jacket, special attention must be paid to water quality. Poor water quality can cause scale or sludge to form on the heat exchange surfaces. It affects the heat exchange efficiency between materials.
First, cool it down to room temperature using circulating water, and then use freezing for further cooling. But the main problem for the poster is insufficient cooling capacity; it’s better to increase that capacity
What other methods might be useful?
Circulating water air-cooled tower. Circulating water air-cooled tower
Pay attention to the water quality; additionally, you can try increasing the flow rate of the cooling water.
The key is to monitor the cooling effect of the circulating water; if it is not satisfactory, it is necessary to modify the water tower used for circulating water. We can provide technical support to convert it into a gas-liquid dual-jet type hollow cooling tower, which offers better cooling performance and significant energy savings. For technical inquiries, please contact liutaoandzdy@sina.com. If needed, the amount of water used for cooling should be increased.
I have seen designs for some refrigeration systems in which the cooling water does not circulate; instead, the process water is used to pass through the condenser before going back into the process water tank. The main risks of doing this are material carryover and \"thermal pollution,\" which need to be considered in light of actual production conditions. This is how we used ammonia pressure refrigeration in the past during summer (the purified river water was pressurized and fed into the condenser, with the outlet connected to a water tank) ； The cooling water for bromine chillers is directly deionized water, with the outlet connected to the process stream (primarily for washing; a higher temperature yields better washing results). Lowering the temperature of the cooling water in the refrigeration system as much as possible is beneficial for improving its efficiency.
It is best to use a brine-based chiller for refrigeration, as it is not affected by water temperature. The higher the temperature, the higher the efficiency. The circulating water has to be handled using a cooling tower; if that doesn’t work, it will have to be discharged directly
