Radiant flux fiber filter

Abstract

The radial flow fiber filter includes container, water inlet, water outlet, horizontal fixed disc and floating disc, fiber stuffing set between the fixed disc and the floating disc, stuffing density regulator, and air distributor. It features the fiber stuffing including layered multiple fiber tows connected horizontally to inner and outer flexible netted cylinders, which have ends connected to the fixed disc and the floating disc separately; the inner flexible netted cylinder provided with vertical porous water distributing pipes fixed to the floating disc; the stuffing density regulator comprising pressure regulating sealer and container water injecting cavity; and the air distributor comprising annular air distributing chamber, air distributing holes in the annular air distributing chamber and the floating disc and controlling pipeline connected together. The present invention has adjustable stuffing density, great filtering capacity and other advantages.

Description

technical field [0001] The invention relates to a radiation flow fiber filter, which belongs to a filter device for water and aqueous solution. Background technique [0002] In the current fiber filter, the fiber bundles are vertically arranged up and down in the container, and one end of the multi-component fiber bundle is tied to a porous fixed plate, and the other end is tied to a weight, a porous movable plate or other movable supporting devices. Filtration direction is upflow, downflow or dual flow. Its density adjustment is realized by adopting such as: Chinese Invention Patent Publication No. CN87100467A and Invention Patent Publication No. CN2095707U disclosed flexible film or flexible bag; another example: CN2138518Y disclosed that water flows through the porous movable plate or the head loss formed by the fiber packing. thrust to achieve. The disadvantages of the above fiber filters are that when the flexible capsule is filled with water and expands, the capsule ...

AI Technical Summary

Problems solved by technology

The disadvantages of the above fiber filters are that when the flexible capsule is filled with water and expands, the capsule is often broken due to the lack of limit protection, and the reliability is poor; the filtration area is reduced due to the existence of the capsule; the effective area of ​​the filler along the filtration direction is gradually reduced due to the capsule. Decrease, forming a speed-up filter, which is not conducive to the protection of water quality

The thrust formed by the pressure head loss is used to realize the structure of the compressed fiber filler. When the water flow velocity fluctuates, the increase of the water head loss will cause the density of the filler and the filtration resistance to increase, thereby affecting the filtration effect and shortening the working cycle. Flow, not ideal for protecting water quality

Moreover, in order to increase the water filtration capacity of the above-mentioned various filters, the diameter of the container must be increased, thereby increasing the floor space.
