Embodiment 1

[0030] like Figure 1-4 As shown, the multi-layer countercurrent unconstrained fiber bundle filter according to the embodiment of the present invention includes a tank body 1 and a water outlet 2 located at the top of the tank body 1, and the bottom end of the tank body 1 is provided with a water inlet 3, The tank body 1 is provided with a porous separator 1 4, a porous separator 2 5 and a porous separator 3 6 in sequence from top to bottom. A filter material layer 1 7 is provided between the second partition plate 5, and a filter material layer 2 8 is arranged in the tank body 1 and located between the porous partition plate 2 5 and the porous partition plate 3 6. The first separator 4 , the second porous separator 5 , and the third porous separator 6 are provided with stainless steel metal meshes 9 , and one side of the tank body 1 is provided with symmetrically arranged hand holes 10 .

Embodiment 2

[0032] like Figure 5 As shown, a filtering method of a multilayer countercurrent unconstrained fiber bundle filter is provided, which is used for the multilayer countercurrent unconstrained fiber bundle filter, comprising the following steps;

[0033] Step S101, entering the raw water to be filtered from the water inlet 3 of the tank body 1 and discharging it from the water outlet 2, and making the filter material layer one 7 and the filter material layer two 8 in a suspended state under the impact of the water flow;

[0034] Step S103, since the direction of water flow is from bottom to top, the filter material is evenly compressed from bottom to top to the point where the top of the filter material is dense and the bottom is sparse, and the dirt particles are gradually retained from large to small and from bottom to top;

[0035] Step S105, when the water resistance increases to a certain extent and needs to be cleaned, a mixture of air and water is fed into the water inlet...

Abstract

The invention discloses a multilayer countercurrent unconstrained fiber bundle filter which comprises a tank body and a water outlet located at the top end of the tank body, a water inlet is formed in the bottom end of the tank body, and a first porous partition plate, a second porous partition plate and a third porous partition plate are sequentially arranged in the tank body from top to bottom. A first filter material layer is arranged in the tank body and located between the first porous partition plate and the second porous partition plate, and a second filter material layer is arranged in the tank body and located between the second porous partition plate and the third porous partition plate. The invention has the beneficial effects that from bottom to top, one to more layers of filter materials are arranged, and the filter materials become fine from coarse to fine, so that gradual fine filtration is formed. Countercurrent filtered raw water enters from the lower part and exits from the upper part, a filter material is supported and compacted by inflow water, the filtering precision is improved, filtered dirt is easy to clean, the running filtering resistance is small, the power consumption is reduced, the filtering effect is recovered by flushing, the flushing water is raw water and returns to a sedimentation tank, the flushing water does not consume water, the equipment and pipeline valves in all levels of equipment are simplified, and the cost is reduced. And the cost of the equipment is also reduced.

Description

technical field [0001] The invention relates to the technical field of unconstrained fiber bundle filters, in particular to a multi-layer countercurrent unconstrained fiber bundle filter and a filtering method. Background technique [0002] Fiber filter is a kind of filter commonly used in water treatment process. When using it for filtration, the fiber bundles in the filter are required to be in a tightly packed state to achieve a good filtering effect; when backwashing, the fiber bundles are required to be loose. state to ensure dirt flushing. The existing constrained fiber bundle filter has complex structure, single filter material, needs to be further improved in filtration accuracy, high cost, and difficult to clean after fouling, which shortens the service life of the filter and increases the number of unconstrained fiber bundle filters. operating and maintenance costs. [0003] For the problems in the related technologies, no effective solutions have been proposed s...
