Cyclone surface cloth water type activated carbon filter

Abstract

The invention relates to a rotational flow surface water distribution type activated carbon filter, which comprises a tank. The tank is internally provided with a medium filtration layer, the medium filtration layer consists of two layers of brackets separating the tank into four chambers, a conical water collection barrel disposed at the bottom of the first layer of bracket, and activated carbon fillers arranged on the brackets. A water distribution device connected to a water inlet line is disposed above the first layer of bracket and near the upper end of the tank, the tail end of the water collection barrel is also connected to a water distribution device, and the water distribution device comprises a gradually increasing conical cylinder, several rotational flow water distribution plates that are arranged around the circle center in the cylinder and enable circumferential uniform distribution of effluent water along the plates, and a center flow baffle. The rotational flow water distribution plates radiate all around from a water inlet point, the center is higher than the periphery, and the center flow baffle is equipped with array eyelets that can ensure uniform and stable water outflow at the center and reduce the impact of water flow to the rotational flow water distribution plates.

Description

technical field [0001] The invention relates to the field of environmental protection sewage, in particular to a multi-media filter. Background technique [0002] Activated carbon filter composition: mainly composed of the following parts: supporting pipelines and valves. The filter body includes: ①Cylinder body; ②Backwash air pipe; ③Water distribution component; ④Support component; ⑤Filter material; [0003] Activated carbon adsorption filter is a pressure filter device with activated carbon as the filter material, which can be connected in series with ion exchange softening and desalination equipment to form a treatment system. Activated carbon filters do their job by passing through a bed of carbon. The activated carbon particles that make up the carbon bed have a lot of micropores and a huge specific surface area, and have a strong physical adsorption capacity. The water passes through the carbon bed, and the organic pollutants in the water are effectively adsorbed by...

AI Technical Summary

Problems solved by technology

[0005] The existing media filter such as activated carbon filter has only one layer of porous plate inside, and all the different filter materials are in one cabin, so the filtering effect is not good

In addition, if the backwash water and air pressure are not well controlled during backwashing, it is easy to cause chaos. Once the effect of chaos filtration is greatly reduced, and the service life of the filter material is very short
