On the necessity of installing a larger drain valve at the cooler inlet – a reward of 20 will be given for replies
Thread Content
As the title suggests, in summer, high temperatures due to weather conditions cause the water temperature in the circulation system to rise. At the same time, because the coolers are in use for a long time, scaling or accumulation of sludge on the tube bundles reduces their cooling efficiency. Is it possible to improve this cooling efficiency by installing a larger drain valve after the inlet valve and using backwashing to remove the sludge? Those with experience, please speak up!
In summer, the increase in the temperature of the circulating water, along with scaling or sludge accumulation in the tube bundles, does indeed significantly reduce the efficiency of the cooler. Installing a larger drain valve after the cooler inlet to carry out regular or irregular backwashing is indeed a viable solution. This method can effectively remove contaminants from the pipes, helping to restore or improve cooling efficiency. However, it should be noted that the frequency and intensity of backwashing need to be moderate; excessive backwashing may damage the pipes, while too low a frequency may fail to achieve the desired cleaning effect. Therefore, the actual condition of the equipment should be carefully assessed and professional advice sought prior to implementation, to ensure a balance between safety and effectiveness. At the same time, adjustments to system pressure and water flow should also be considered to ensure the stability of the system during operation. .
Using backflushing for cleaning the tube side is feasible without affecting equipment operation, whereas backflushing for cleaning the shell side is not advisable. Due to limitations in the shell-side structural design, conditions for high-flow-rate flushing cannot be met. The best way to address such problems is to purify the fluid before it enters the cooler, thereby reducing deposition within the cooler. For example, installing a self-centering purification tank and filters to remove deposited suspended impurities,,,,,. For reference.

Using a larger drain valve behind the inlet valve to flush out sludge through backflow is a viable technical solution for improving cooling efficiency. In actual production, employing a circulation method between the outlet and the inlet can effectively remove dirt and enhance the heat exchange performance of the heat exchanger
Is a circulation system in place for the inlet and outlet, with a pump installed?
We’ve installed pumps; when they’re not needed, we can simply remove them. Since they’re not used very often, the quality of our circulating water remains acceptable
Could you elaborate on the disadvantages or hazards of backwashing for silt removal?

For those with modest requirements, online dredging can be carried out as long as the temperature fluctuations remain within acceptable limits. The key is that the downstream production conditions permit the formulation of a suitable dredging plan. As for the disadvantages, during the dredging process, it can cause fluctuations in the cooling temperature, leading to temporary increases in temperature, and there is also a possibility of damaging the equipment.
