Large resistance gas distribution, medium resistance water distribution system and device for water gas back flush of filter tank

Abstract

The invention relates to a system used to wash the filter pool, which will distribute gas in large resistance and distribute water in middle resistance, wherein it comprises a water distribute groove at the bottom of filter pool, a water gas distribute arc device, a gas inlet tube, and a T-shape gas distribute tube; the middle of pool bottom has a concave water distribute groove; the gas inlet tube is in the water distribute groove to extend to the end of groove; the water gas distribute arc device comprise several arc tubes mounted on the bottom and span the water distribute groove; under each row of arc tubes, the gas inlet tube is connected to one T-shaped gas distribute tube; the transverse tube of said T-shape gas distribute tube is at the upper part of arc tube. The invention has standard elements, simple installment, and low demand on the horizontal level of pool bottom. The whole installment only needs 1-2 weeks.

Description

technical field [0001] The invention belongs to equipment in the field of water treatment and filtration, in particular to a filter water distribution and gas distribution system and device used in the gas-water backwash filtration process. The equipment realizes the uniform distribution of filter backwash gas and water to obtain good Backwash effect. Background technique [0002] Filtration is the main process of water treatment, and the filter tank is the most important treatment structure of the water plant. The filter is to remove the granular suspended impurities in the water through the interception of the filter material in the pool. When the amount of impurities retained by the filter material reaches a certain level, that is, after reaching the saturated amount of the filter material, it is necessary to clean the filter material by backwashing. , so that the filter material can be re-applied to the filtration process. In order to reduce the water consumption and el...

AI Technical Summary

Problems solved by technology

[0008] In order to overcome the problems of poor water and gas distribution uniformity, long installation period and difficult construction in the existing gas-water backwashing filter water distribution and gas distribution system, the present invention proposes a large resistance gas distribution, medium resistance Water distribution system, the system has good air and water distribution performance, and has low requirements for civil construction, the allowable error can reach ±15mm, and the installation of a single filter can be completed in 2 to 3 days, which can greatly shorten the construction period of the filter
