Description
Technical field
The present invention relates to water treatment facilities, are concretely a kind of filter visual devices and accurate filter.
Background technology
Traditional accurate filter is stainless steel or carbon steel hermetic type equipment, closed housing built with filter core or
Filter bag is as filter element, and constantly accumulation pollutant, filtration resistance constantly increases on filter core or filter bag during the filter use
Add, the situation of change that differential water pressures are passed in and out by observing accurate filter reflects the pollution situation of filter element, and judges filtering element
Whether part should be changed.
Because the replacing of filter element is only judged by the change of pressure, and pressure pressure changeable constant interval compared with
Small, pressure difference change is insensitive, following point easily occurs during accurate filter use：
(1) when pollutant accumulation is to certain thickness, filtration resistance increases suddenly, in addition filter core or filter bag flattened or
Person punctures, and this process duration is short, if accurate filter filter element flattens or breakdown is not found in time, secondary filter
The follow-up of device will be contaminated quickly by protection equipment.
(2) after filter element is breakdown or flattens, the disengaging differential water pressures of accurate filter will no longer change, easily to behaviour
Misled as personnel, produce the illusion that need not temporarily change filter element, actually pollutant is transferred into and protected
Equipment, cause protected follow-up equipment pressure difference rise or even be forced out of service.
(3) because accurate filter Inlet and outlet water gage pressure excursion is small, pressure difference amplitude of variation is insensitive, Jin Jinguan
Pressure difference is examined, the situation of distortion easily occurs, is easily delayed the best opportunity of the replacing of filter element.
(4) pollution of accurate filter is only capable of reflecting from pressure difference, it is impossible to the real dirty stifled reason of reflection in time and dirt
Thing state is contaminated, is unfavorable for taking targetedly corrective measure to the pretreatment before accurate filter.
