The invention belongs to the technical field of purifying and processing of industrial circulating water, and particularly relates to a vertical self-cleaning filter and a self-cleaning method. The filter comprises a water inlet, a water outlet, a high-pressure cavity, a filter cavity, a water inlet cavity, a sewage suction machine and a high-precision filter net; the water inlet and the high-pressure cavity are respectively arranged at one end of the filter; the water outlet is arranged at one side of the filter; the filter cavity is arranged inside the filter; the water inlet cavity is arranged at the upper end of the water inlet and separated from the filter cavity; the sewage suction machine is arranged inside the high-precision filter net; the high-precision filter net is arranged inside the filter cavity; and a certain quantity of sewage suction devices are arranged at one side of the sewage suction machine. According to the vertical self-cleaning filter and the self-cleaning method disclosed by the embodiment of the invention, automatic filtering can be achieved under a complicated water quality environment, and the problem that the filter system cannot be completely self-cleaned due to insufficient suction force of a suction nozzle when the pressure of a water system is too low, so as to affect the filter function, is avoided. Thus, the self-cleaning stability of the filter system is ensured.
Description
technical field [0001] The invention belongs to the technical field of industrial circulating water purification treatment, and in particular relates to a vertical self-cleaning filter and a self-cleaning method. Background technique [0002] The filter structure for on-line purification of industrial circulating water is generally as follows: figure 1 As shown, the raw water is input into the coarse filter chamber 92 from the water inlet 91, the impurities with larger particles in the raw water are intercepted by the coarse filter screen 93, and then enters the fine filter chamber 94, and the purified water is further filtered by the fine filter screen 95 from the water outlet 96 discharge. After filtering for a certain period of time, a layer of impurities will often accumulate on the inner wall of the fine filter 95, and a gradually increasing pressure difference will be generated inside and outside the fine filter 95. When the pressure difference is too large, it will a...
