Abstract

The pressure stabilizing filter tube with double air cushion layer and independent water distribution and air distribution set transversely in filter has semi-circular upper part, rectangular lower part and middle part separated with partition board into one upper air distributor and one lower water distributor. The air distributor has residual air releasing hole in the top, back flushing air releasing holes in the side walls and balance holes in the root of side walls. The bottom plate of the filter tube, i. e., the water distributor, is provided with water distributing holes. The air distributing duct penetrating the partition board between the air distributor and the water distributor has residual air releasing hole and air inlet slot. The present invention has low power consumption, capacity of raising water quality and high operation efficiency.

Description

(1) Technical field [0001] The invention relates to a water treatment device, in particular to a water distribution and gas distribution device used for filter tank backwashing. (2) Background technology [0002] At present, the siphon filters, ordinary fast filters and double valve filters built in the early stages of domestic and foreign water plants are still in large numbers. Since the above-mentioned filter only adopts the water washing method during backwashing, the production efficiency is low, the energy consumption of backwashing is high, and the degree of cleanliness of the filter material is low. [0003] In the early 1990s, the French Deliman Water Company developed a new type of air-water backwash filter - the V-shaped filter. Because of the combination of air and water backwash, the cleanliness of the filter material is comparable to that of the filter. The operating cycle of the pool has been greatly improved, so the V-type filter has been rapidly promoted an...
