A filter air-water distribution device

Abstract

The invention discloses an air-water distribution device for a filter, which is characterized in that the air-water distribution device includes a stainless steel box body, the stainless steel box body is attached to the outside of the central water collection channel of the filter pool, and the stainless steel box body is set There is a stainless steel partition, which divides the stainless steel box into two parts: the upper air chamber and the lower water chamber. The upper air chamber is close to the side of the central water collection channel of the filter with air intake holes, and the lower water chamber is close to the side of the central water collection channel of the filter tank. A water inlet hole is provided, the air inlet hole is close to the top of the central water collection channel, and the water inlet hole is close to the bottom of the central water collection channel. After installing the device on the outside of the sand filter and activated carbon filter central collection channel, it can solve the problem of increased construction difficulty, difficulty in guaranteeing construction quality, and increased civil engineering costs due to the fact that the bottom of the filter pipe gallery is lower than the bottom plate of the filter body. The problem of reducing the effective volume of the lower stacked pool. The device is simple, reliable, and easy to install and manage.

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 ...
