The traditional precision filter is a stainless steel or carbon steel closed type device, a filter element or a filter bag is arranged in a closed shell and serves as a filter element, pollutants are continuously accumulated on the filter element or the filter bag in the using process of the filter, the filtering resistance is continuously increased, the pollution condition of the filter element is reflected by observing the change condition of the water pressure difference of the inlet and the outlet of the precision filter, and whether the filter element is required to be replaced or not is judged.
Because the replacement of the filter element is judged only by the change of pressure, the pressure change and pressure change interval is small, the differential pressure change is insensitive, and the following problems are easy to occur in the using process of the precision filter:
(1) when the pollutants are accumulated to a certain thickness, the filtering resistance is suddenly increased, even the filter element or the filter bag is crushed or punctured, the process lasts for a short time, and if the crushing or the puncturing of the filtering element of the precision filter is not found in time, the subsequent protected equipment of the precision filter is quickly polluted.
(2) When the filter element is punctured or flattened, the pressure difference of inlet and outlet water of the precision filter does not change any more, misleading is easy to generate for operators, false images that the filter element is not needed to be replaced temporarily are generated, and in fact pollutants are transferred to protected equipment, so that the pressure difference of the protected subsequent equipment is increased and even the protected subsequent equipment is forced to stop running.
(3) Because the pressure change range of the water inlet and outlet pressure gauge of the precision filter is small, the change amplitude of the pressure difference is insensitive, the situation of distortion is easy to occur only by observing the pressure difference, and the optimal time for replacing the filter element is easy to delay.
(4) The pollution of the precision filter can only be reflected from the pressure difference, and the real pollution blockage reason and the pollutant state can not be reflected in time, so that the method is not beneficial to adopting targeted improvement measures for the pretreatment before the precision filter.
