Abstract

The invention discloses an air distribution system of a filter. The filter (3) is arranged on a back-flushing ditch (1); an air distribution branch layer (10) and a filter brick group (11) are arranged at the bottom of the filter (3); a gravel supporting layer (8) and a filtrate layer (9) are arranged inside the filter (3); a drainage channel (20) is arranged at the upper end of the filter (3); an air distribution pipe group (7) is located on the wall of the filter between the filtrate layer (9) and the drainage channel (20) and consists of a main pipe bracket (13), an air distribution main pipe (16), an air distribution main pipe descending branch joint (17) and a flexible high-pressure rubber pipe (18); and the bottom of the flexible high-pressure rubber pipe (18) is communicated with the air distribution branch layer (10). According to the filter system provided by the invention, not only can the air distribution property be improved, but also the pipeline cost and the mounting cost are reduced, so that the air distribution system of the filter provided by the invention is easier to mount, and the operability of maintenance in later is enhanced.

Description

technical field [0001] The invention relates to a gas distribution system for a filter tank. Background technique [0002] The air distribution function of the filter system is mainly used in the three-stage filtration filter, denitrification filter and biological aerated filter for sewage treatment. At present, the filter system in the market is to set the air distribution pipe group under the ground. The performance of gas distribution is low, the pipeline cost is high, the installation cost is high, and there are many inconveniences in installation. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a filter air distribution system, which can not only improve the performance of the air distribution, but also reduce the pipeline cost and installation cost, make the installation easier, and enhance the operability of later maintenance. [0004] The present invention adopts the following technical solutions: a fi...
