Filter-pool gas-water distribution apparatus

Abstract

A disclosed filter-pool gas-water distribution apparatus is characterized in that the gas-water distribution apparatus comprises a stainless steel box body; the stainless steel box body is attached to the outer side of a filter-pool central water-collecting channel, and the stainless steel box body is inside provided with a stainless steel separation plate which divides the stainless steel box body into an upper gas cabin and a lower water cabin; one side, tightly attached to the filter-pool central water-collecting channel, of the upper gas cabin is provided with an air inlet; one side, tightly attached to the filter-pool central water-collecting channel, of the lower water cabin is provided with a water inlet; and the air inlet is tightly attached to the top of the central water-collecting channel, and the water inlet is tightly attached to the bottom of the central water-collecting channel. By arranging the apparatus at the outer sides central water-collecting channels of a sand filter pool and an active-carbon filter pool, the apparatus can help to solve the problems that because the pipe gallery bottom of a filer pool is lower than a filer-pool body bottom plate, the construction difficulty is increased, the construction quality is difficult to guarantee, civil engineering cost is increased, and the lower stacked pool effective volume is reduced. The apparatus has the characteristics of being simple, reliable and easy to installation and management.

Description

technical field [0001] The present invention relates to the technical field of filters, in particular to an air-water distribution device installed between the filter tank body and the pipe gallery and attached to the outside of the central sump of the filter tank, through which the air-water distribution device can change Adjust the setting position and elevation of filter air flushing and water flushing (and outlet pipe) to effectively solve the problem of increased construction difficulty due to the fact that the bottom of the filter pipe gallery is lower than the bottom plate of the filter body, construction quality is difficult to guarantee, and civil engineering costs increase , The problem of the effective volume reduction of the superimposed clear water pool in the lower part of the filter tank. Background technique [0002] At present, in the water purification system of conventional treatment and advanced treatment in existing waterworks, sand filter and activated ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an air-water distribution device for a filter, which is installed in the design of the filter, which can solve the problem of the reduction in the effective volume of the lower stacked clear water pool caused by the protruding lower part of the filter pipe gallery and the combination of Solve the problem that the bottom of the filter pipe gallery and the bottom plate of the filter are staggered, resulting in difficult construction, difficulty in guaranteeing construction quality, and increased civil engineering costs
