Improved multi-tube filter

Abstract

The invention relates to an improved multi-tube filter which comprises a base, a plurality of filter cylinders are arranged on the base, water baffles are arranged on the periphery of the upper portion of the base, a plurality of liquid collecting tubes and a plurality of filter elements in threaded connection with the liquid collecting tubes are arranged in the filter cylinders, and clamping structures are arranged at the threaded connection positions of the filter elements and the liquid collecting tubes. Vertical supporting plates are arranged on the upper portions of the liquid collecting pipes, transverse partition blocks are arranged between the adjacent liquid collecting pipes, and a filter valve is arranged at an inlet of the filter cylinder. It can be guaranteed that the screwed filter element is not prone to falling off, the liquid collecting pipe is not prone to bending deformation, the connecting portion of the liquid collecting pipe and the wall of the filter cylinder is not prone to damage, impurities in fluid can be filtered out, the impurities are prevented from being attached to the interior of the valve body, and the phenomenon of pipe explosion caused by pressure increase is avoided.

Description

technical field [0001] The invention relates to a filter, in particular to a multi-tube filter. Background technique [0002] The PTA mother liquid wastewater in the petroleum and chemical industries has high turbidity and many impurities, but the treatment requirements imposed by the policy are high, so the treatment is difficult. At present, the device for solid-liquid separation of PTA waste liquid includes a filter cylinder, which is provided with a plurality of liquid collection pipes and a plurality of filter cores screwed on the liquid collection pipes, but in the filtration process, Because the filter cake adheres to the surface of the filter element, the filtration resistance increases, and the filter element needs to be cleaned by pressure backflushing to make the filter cake accumulated on the surface of the filter element fall off, so that the filter element can continue to filter. This kind of backflush needs Often intermittently. Because the pressure back blo...
