Problems solved by technology

[0002] There are usually three types of fluid filtration, tube filtration, plate filtration, and disk filtration. Basically, the outer surface of the filter is in contact with the unfiltered fluid, and the inner surface of the filter is in contact with the filtered fluid. Although there is also a backwashing mechanism, However, the filtration operation is often stopped during backwashing, and the backwashing effect is poor, frequent maintenance and replacement of filter elements, and high cost

Abstract

The invention belongs to the technical field of filter equipment, and provides a fluid filter. The fluid filter comprises a container shell, a feeding port, a discharge port, filter bodies, a rotary displacement back flushing mechanism and a rotary displacement pollutant discharge mechanism; the rotary displacement back flushing mechanism and the rotary displacement pollutant discharge mechanism are used for carrying out back flushing on a group of filter units and pollutant discharge; and the other filtering units are in a normal filtering state. Fluid treated by the fluid filter provided bythe invention, especially coal tar or crude oil, reach a specified filtering precision, and the filuid filter is reliable in operation, free of interruption, free of faults, free of maintenance, low in cost, long in cycle operation, less in emission of dust pollutant and extremely high in popularization value.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a fluid filter. Background technique [0002] There are usually three types of fluid filtration, tube filtration, plate filtration, and disk filtration. Basically, the outer surface of the filter is in contact with the unfiltered fluid, and the inner surface of the filter is in contact with the filtered fluid. Although there is also a backwashing mechanism, However, the filtration operation is often stopped during backwashing, and the backwashing effect is poor, and the maintenance and replacement of filter elements are more frequent and the cost is higher. With intensive production, a large amount of fluid circulation, sewage treatment puts forward higher and higher requirements for filtration technology and equipment, and the pretreatment before the deep processing of a large amount of coal tar also places more emphasis on the requirements for filtration. The fluid reaches the...
