Problems solved by technology

Whether this filter is used to filter liquid or gas, its working principle is interception, and a filter cake is formed on the filter layer. When the differential pressure reaches a certain level, backwashing is performed, and the effect of backwashing is very bad.
[0004] Reason 1. When the folded microporous filter element forms a filter cake, the folded gap is already filled with pollutants, and some of them are caught by the folded filter element, which is not easy to backwash; With special structure, backwash water or air cannot be cleaned along the vertical direction of the filter surface, most of them are close to the parallel direction of the filter surface, such backwash force will have very little impact on the dirt in the filter membrane, and it is difficult to clean the goal of
In addition, this kind of backwashing force will have less impact on the dirt sandwiched between the two filter membranes, so the filter with this structure does not have self-cleaning ability, and it needs a lot of energy to be effective when backwashing

Embodiment 1

[0039] see figure 1 , the present invention discloses a schematic structural view of Example 1 of a high-throughput anti-pollution microporous filter, the filter includes an inner filter membrane 1, an outer filter membrane 2, a clean water channel 3, an unfiltered water channel 4, and an unfiltered water channel 4. Water channel sealing strip 5, filter membrane support 6, clean water channel sealing strip 7.

[0040] see figure 1 , figure 2, the spiral plate filter core is processed by rolling up two microporous filter membranes, the inner filter membrane 1 and the outer filter membrane 2, and several filter membrane supports 6 are embedded between the two microporous filter membranes for Keep the distance between the two microporous filter membranes, and at the same time have the effect of reinforcing the filter core; on the top of the filter core, an unfiltered water channel sealing strip 5 is installed to prevent unfiltered water from entering the upper water purificati...

Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 is that in this embodiment, two layers of microporous filtration membranes are rolled together to form two channels, one for unfiltered water and one for filtered water; unfiltered water The way of inflow is one of the following two ways, the first way: unfiltered water enters from the outside of the filter, the second way: unfiltered water enters from the center of the filter.

[0047] The first method: the unfiltered water first enters the middle of the two layers of microporous filter membranes from the secondary outer side at a relatively high flow rate, and the water flows back out from the bottom after flowing to the bottom, forming a vortex flow between the lower part of the filter and the middle of the filter layer, so that When the filter layer exits, a large tangential scour force is formed, which is beneficial to remove the sediment on the filter surface, and the space under the filter is also conducive t...

Abstract

The invention discloses a high-flux anti-pollution microporus filter and a filtering method thereof. The filter comprises an inner side filtering membrane, an outer side filtering membrane, clear water channels, unfiltered water channels, seal strips for the unfiltered water channels, filtering membrane supports and seal strips for the clear water channels. A filter element of the filter is a spiral structure formed by rolling and machining the inner side filtering membrane and the outer side filtering membrane, the multiple filtering membrane supports are inlaid between the two filtering materials, and the seal strips for the unfiltered water channel and the seal strips for the clear water channels are installed on the upper edge and the lower edge of the filter element in a spaced mode respectively and have the function of stopping unfiltered water from entering an upper clear water region and the function of stopping filtered clear water from back flowing to a lower unfiltered region respectively. According to the high-flux anti-pollution microporus filter and the filtering method thereof, the pollution resisting effect is good, the service life is long, and the filtering capacity per unit volume is large.

Description

technical field [0001] The invention belongs to the technical field of filtering devices, and relates to a filter, in particular to a high-throughput anti-pollution microporous filter; meanwhile, the invention also relates to a filtering method of the filter. Background technique [0002] Microporous filter is a kind of equipment that is widely used in daily life and industrial process. The key component in the filter is the filter element. The structure of the commonly used microporous filter element in the market is folded. [0003] The advantage of the folded microporous filter element is that the filter surface per unit volume is large and the dirt holding capacity is large. Whether this filter is used to filter liquid or gas, its working principle is interception, and a filter cake is formed on the filter layer. When the differential pressure reaches a certain level, backwashing is performed, and the effect of backwashing is very bad. [0004] Reason 1. When the folded...
