Description

A New Type of Automatic Cleaning Circulating Water Filter

Technical field:

The utility model relates to a filter, in particular to a novel automatic cleaning circulating water filter.

Background technique:

The circulating water of the coal chemical plant is often used as cooling water for each workshop of the plant, and most of the supplementary water is the water from the sewage treatment station and the fire water. Due to the poor water quality of the sewage treatment station, a large amount of impurities enter the circulating water, and the filter screen is prone to clogging after a long operation time. The more impurities in the circulating water, the higher the frequency of cleaning the filter screen.

Most of the current filters have no automatic cleaning function, and often need to stop production and clean regularly. When the filter cleaning interval is less than one production process cycle, normal production cannot be carried out or the production will be greatly affected, especially for filter cleaning and maintenance. The process is labor-intensive and time-consuming, which not only brings a lot of trouble to the user, but also seriously affects the production efficiency; in addition, the current filter mostly adopts a one-stage filtration method, once the filter screen is blocked or malfunctions, it will directly affect filter effect.
