Background technology
It is inhomogeneous to exist recoil at present filter, the high and many problems of recoil water consumption of residue deposition rate:
A kind of high efficiency particulate air filter is disclosed in patent [200920239599.9], its structure comprises the filter tank body and fills in self adaptation comet formula fiber filtering among the filter tank body, rational backwash space is left in the top of self adaptation comet formula fiber filtering, in tank body, also be provided with run through self adaptation comet formula fiber filtering on three-way pipe and following three-way pipe; The wherein two-port of last three-way pipe is positioned at the inner chamber middle and lower part of filter tank body, is respectively and just washes water inlet and backwash delivery port, and the 3rd port of last three-way pipe stretches to the interior top of chamber of filter tank body; The wherein two-port of following three-way pipe is positioned at the inner chamber middle and lower part of filter tank body, is respectively the backwash water inlet and is just washing out the mouth of a river, and the 3rd port of following three-way pipe stretches out from the bottom of filter tank body for just washing discharge outlet.But it lacks the water distribution distribution device, can occur serious inhomogeneous and recoil dead band during down to recoil, has not only increased water consumption, but also has shortened greatly the service life of filter.
The utility model content
In order to solve the shortcoming that prior art exists, the utility model specifically discloses a kind of regeneration membrane filter.
The technical solution adopted in the utility model is as follows:
The regeneration membrane filter, comprise the filter tank body and fill in self adaptation comet formula fiber filtering among the filter tank body, the backwash space is left in the top of self adaptation comet formula fiber filtering, be provided with water inlet at the tank body top, side at water inlet is provided with steam vent, is provided with delivery port in the bottom of tank body; Be provided with maintenance inlet and the Pressure gauge that communicates with it in the outside in backwash space, on the tank wall of filling self adaptation comet formula fiber filtering, be provided with the maintenance hand hole, below self adaptation comet formula fiber filtering, be provided with some water distribution distribution devices.
Described water distribution distribution device comprises a vertically pipe, is provided with a plurality of qi-emitting holes and distributing hole on described vertical pipe, is provided with filter on the top of vertical pipe, is provided with the filter cap on filter.
Be connected by set bolt between described vertical pipe and the filter.
Described distributing hole is the bar shaped seam.
Parallel and equally spaced being located on the PP plate of described some water distribution distribution devices.
Bottom at tank body is provided with supporting leg, is provided with hanger in the both sides at tank body top.
Top in tank body is provided with an application of anti-leakage layers that communicates with water inlet.
The bottom of the side of described tank body is provided with the recoil air inlet.
Described long tube is of a size of
The bar number of bar shaped seam is 40, and gap width is 0.35mm, slit area 3.35cm
2
The course of work of this device is as follows:
1 filter process: the water that need handle enters from water inlet, handles through the comet type fiber filtering, flow out from delivery port again to enter clear water reserviors,
2 gas are broken through journey: gas is entered by the recoil air inlet, by the water distribution distribution device, enters filter cap and filter, recoils dirtyly to discharge from water inlet;
3 air water back washings: gas is entered by the recoil air inlet, and recoil water enters by delivery port among the figure, by water distribution distribution device among the figure, enters filter cap and filter, recoils dirtyly to discharge from water inlet;
4 washings separately: recoil water enters by delivery port, by the water distribution distribution device, enters filter cap and filter, recoils dirtyly to discharge from water inlet.
The beneficial effects of the utility model: the water distribution distribution device makes and makes the water distribution of filtration even when filtering, and recoil water and back flushing air are evenly distributed.Filter and consider cap and can prevent that filtrate from running out of from the bottom; Increase filtering accuracy; Filtrate is more even.When can preventing the filtrate recoil, application of anti-leakage layers runs out of from the top.Total structure filtering accuracy height, the rate of filtration is fast, and pollutant holding capability is big, and the backwash water consumption rate is low, and it is low to add dose, and the water distribution gas distribution is even, and residue deposition rate is low.
The specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing:
As shown in Figure 1, 2, the regeneration membrane filter, comprise filter tank body 15 and fill in comet formula fiber filtering 7 among the filter tank body, backwash space 11 is left in the top of comet formula fiber filtering 7, be provided with water inlet 6 at tank body 15 tops, side at water inlet 6 is provided with exhaust outlet 10, is provided with delivery port 8 in the bottom of tank body 15; Be provided with maintenance population 4 and the Pressure gauge 12 that communicates with it in the outside in backwash space 11, on tank body 15 outer walls of filling comet formula fiber filtering 7, be provided with maintenance hand hole 3, below comet formula fiber filtering 7, be provided with water distribution distribution device 14.Water distribution distribution device 14 comprises a vertically pipe 21, is provided with a plurality of qi-emitting holes 19 and distributing hole 20 on described vertical pipe 21, is provided with filter 17 on the top of vertically managing 21, is provided with filter cap 16 on filter 17.Vertically be connected by set bolt 18 between pipe 21 and the filter 17.Be provided with supporting leg 1 in the bottom of tank body, be provided with hanger 5 in the both sides at tank body top.Distributing hole 20 is the bar shaped seam.Top in tank body 15 is provided with an application of anti-leakage layers 9 that communicates with water inlet 6.The bottom of tank body 15 is provided with recoil air inlet 2.Several years water distribution distribution device 14 parallel and equally spaced being located on the pp plate 13.
