A kind of powder resin filter online film laying system

Abstract

The invention discloses a powdery resin filter online film laying system. The system is characterized in that a film laying case is provided with an inclined insert type electric stirrer and a floating ball liquid level switch. The system has the following advantages: 1, the filter element of a filter is repaired and thickened in the running process, so the running period is improved; 2, the adoption of the inclined insert type electric stirrer prevents a material liquid in the film laying case from forming a vortex, is in favor of the full and uniform mixing of the material liquid, and is also in favor of conveying the material liquid; 3, an advanced film laying pump adopts a medium pressure resistant pump shell, and is a metering pump capable of conveying a slurry, and the arrangement of a safe valve at the outlet tube of the pump is helpful for avoiding impact from a medium pressure system; 4, the powdery resin filter online film laying system is connected with the powdery filter, and has a running direction consistent with the filter, so online uniform laying and difficult shedding of a powdery resin are benefited; and 5, the powdery resin filter online film laying system has a small occupied area, solves a problem that the a filter which cannot be laid with a film under a medium pressure running condition, improves the use efficiency of the filter, reduces the running cost and reduces the manual labor.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment for fine treatment of condensate, in particular to an online film-laying device for a powder filter, and in particular to its connection structure. Background technique [0002] At present, in domestic thermal power plants, especially air-cooled units, most of the condensate polishing systems use powder resin filters. If the bypass is opened due to the failure of one filter during operation (medium-voltage operation), then , because the differential pressure of the bypass is smaller than that of the other running filter, the other running filter will have an instantaneous flow cut-off, so that due to the loss of the differential pressure inside and outside the filter element, some powder If it falls off, not only the filter element will be polluted, but also the quality of the effluent water will deteriorate and the operating cycle of the filter will be shortened. [0003] At pr...
