About clogging of circulating water heat exchanger
Thread Content
Four months after the maintenance, it was found that the heat exchange effect of a circulating water heat exchanger gradually deteriorated. When the maintenance was dismantled, it was found that the circulating water tubes on the tube side were heavily scaled and blocked. After cleaning, most of them were found to be silt and iron particles. Here are pictures of the structure and scaling of the production equipment. Please help me analyze and provide valuable opinions. Thank you very much! ! Replies will be rewarded
Consider installing a water filter and cleaning it regularly
We still have to start from the source of the water. This water does not meet the requirements for use. This not only needs to deal with physical impurities, but also chemical impurities.
If the water quality is poor, you can add water treatment agent to treat it. During regular maintenance, a filter should be installed to filter out the large ones directly.
Is this the only one? If the heat exchange effect of other water equipment in the system also becomes poor, it should be caused by poor quality of circulating water. 1. The turbidity of the circulating water is high. 2. The hardness of the circulating water is high. 3. The temperature difference of this heat exchanger is large.
A single piece of equipment has just been parked and cleaned.
Just like a set of coolers I dealt with before, the user pumped water directly from the river nearby for cooling. The sludge and wood chips were washed with a high-pressure water gun. In the end, the pipes could only be cut off and boiled with lye. It is recommended that you install two filters on the pipes and clean the filters regularly.
If the circulating water treatment fails, try using a side filter.
Don’t be reluctant to invest in filtration and purification process water. It is not recommended to use well water, river water, lake water, and rainwater directly. . . . Temperature changes in the equipment, coupled with the interaction of impurities, will aggravate the occurrence of scaling and corrosion. Filter or treat it before entering the equipment. * * It will reduce the cost of parking, maintenance, and maintenance, and will also extend the service life of the equipment. Overall, the price/performance ratio is still very high:)
There is so much mud because the water quality is too poor. First filter it, analyze the water quality, and add chemicals.
