Film paving monitoring device for powder resin covering filter

Abstract

The invention discloses a film paving monitoring device for a powder resin covering filter. The film paving monitoring device for the powder resin covering filter comprises infrared waterproof camera monitoring detection equipment (1), an intelligent calculation controller (2) and a supersonic cleaning device (3). Equipment operation and the surface morphology and mounting and fixing conditions of a filter element in the film paving process are continuously monitored by the infrared waterproof camera monitoring detection equipment (1) arranged at the two thirds height at the straight edge of the powder resin covering filter, and the film paving thickness is calculated by the intelligent calculation controller (2). The surface of a camera lens is cleaned by the supersonic cleaning device (3) and the measuring precision is prevented from being influenced by dirty attachment. The infrared waterproof camera monitoring detection equipment (1) has both the video monitoring and the measuring function for the film paving thickness, can accurately control the film paving process and the film paving thickness, and solves the phenomena of short operation period, incomplete film explosion and uneven film paving in the existing powder resin filter, and the automated control level of a condensed water polishing system of an air cooling unit is improved.

Description

technical field [0001] This patent relates to a film-laying monitoring device for a powder resin-covered filter, especially for the operation film-laying control of a powder resin-covered filter in an air-cooled thermal power plant condensate treatment system. The cover filter is to cover the outer surface of the filter element with filter aids of different materials. With the help of the filter material bridging principle, it forms a dense covering layer. When the filter resistance reaches a certain value or the water quality deteriorates, the membrane will be blasted with water and air. Rinse and then reapply filter aid to restore its functionality. Background technique [0002] Powder resin covered filter is mainly used in condensate polishing system of air-cooling unit and condensate polishing system of nuclear power plant. The powder resin filter is essentially the application of the thin-layer ion exchange method, but its resin particle size is smaller (about 0.1mm) a...

AI Technical Summary

Problems solved by technology

However, at present, all powder resin covered filters are manually observed and judged through peepholes installed on the filter. There is no scientific quantitative analysis method, and the observation range is limited, which affects the safe and effective operation of the system, and the degree of automation is low.
