A high-speed filter with a siphon automatic residual pressure exhaust diversion pressure relief device

Abstract

The invention provides a high-speed filter with a siphon automatic excess pressure exhaust, flow guide and pressure relief device, and relates to a filter with a closed container filled with bulk materials, in particular to a high-speed filter with a device for automatically removing gas in the filter. The high-speed filter comprises a high-speed filter body filled with a granular filter material layer, and the siphon automatic excess pressure exhaust, flow guide and pressure relief device is arranged. The exhaust, flow guide and relief device comprises an exhaust, flow guide and pressure relief pipe and a Y-shaped filter net. The exhaust, flow guide and pressure relief pipe is vertically installed beside the high-speed filter body, the inlet end of the exhaust, flow guide and pressure relief pipe is connected to an exhaust valve inlet pipeline of the high-speed filter body, the outlet end of the exhaust, flow guide and pressure relief pipe is connected to a backwashing water outflow valve outlet pipeline of the high-speed filter body, and the absolute height difference exceeds the vertical height of the high-speed filter; hidden danger that air is accumulated in the high-speed filter and a compressed air layer is formed on the upper portion can be eliminated, zero-energy-consumption exhaust, flow guide and pressure relief and zero pollution and zero discharge of the high-speed filter are achieved, exhaust noise pollution is eliminated, and the service life of an exhaust valve and a filter material is prolonged.

Description

technical field [0001] The present invention relates to a filter containing loose material in a closed container, and more particularly to a high-speed filter with an automatic degassing device inside the filter. Background technique [0002] In modern iron and steel enterprises, high-speed filter devices are necessary equipment for each work area of ​​the water treatment plant. In the water treatment process, multiple high-speed filters are installed on the return pipe network of the circulating water system. It is to fill the filter material in a closed pressure vessel, usually a closed steel container, and use the external pressure to overcome the resistance of the filter layer to filter. The high-speed filter mainly plays the role of clarification and filtration to improve the quality of circulating water. The mechanism of filtration is the technical process in which the backwater passes through the porous granular filter material layer (such as quartz sand anthracite, ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a high-speed filter with a residual pressure exhaust diversion pressure relief device to solve the problem that the existing high-speed filter uses an exhaust valve to exhaust air at regular intervals, resulting in unstable filtered water flow, resulting in exhaust valve and Technical problems of shortened service life of high-speed filters
