Description
[technical field]
The present invention relates to a kind of back purge system.
[background technology]
Backwash is air-flow or water to flow through bottom flow distributor back through filter tank, to rinse out filter
Pollutant in material and other blocking material so that filtrate recovers the method for cleaning.At present, filter tank is anti-
The power-equipment of rinse-system fluid is water pump and blower fan respectively.Water pump provides backwash current, and blower fan carries
For backwash gas.The uniform distribution of mixing wastewater with air and backwashed fluid is by the long handle filter being arranged on filter plate
Head realizes.Strainer head is arranged on filter plate by the many employings of backwashing system in existing filter tank.Strainer head
It is a point flushing fluid distributing apparatus, the level that the uniformity of its horizontal level and fluid distribution is installed by filter plate
Degree of accuracy affects.Strainer head is made up of filter and the connected filter bar of jet fluid.The filter of filter
The strip uniformly having processing meticulously in cap cambered surface is carefully stitched, in order to spray gas and water.Filter bar is plastics
Pipe top has aperture, has the fluid inflow short tube that air inlet bar stitches near bottom.
Prior art has the disadvantage in that the power of 1, gas and water needs water pump and blower fan to provide respectively,
Equipment is complicated, and energy consumption is big.2, installing the technology of strainer head on employing filter plate, strainer head is to filter plate
Requirement for horizontality is the highest, and difficulty of construction is relatively big, and workload is big and comparatively laborious.And, once preburying part
Position construction is not in place, easily occurs that fluid runs leakage phenomenon, installs inconvenience.Cause backwash effect poor.
Backwashed fluid intensity is the most uneven, filter some places can be caused excessively to expand, cause filtrate stream
Lose；Some places underexpansion, between filtrate, pollutant rinse insufficient, affect filter effect.

[detailed description of the invention]
Refer to, shown in Fig. 1 and Fig. 2, embodiments of the invention are described in detail.
As it is shown in figure 1, a kind of back purge system involved in the present invention, back purge system includes clear water reserviors
1, water pump 2, water sprayer 3, moisture trap 4, diverter pipeline 5 and plural number fluid distributor 6,
Described water pump 2 is arranged in clear water reserviors 1, and described water pump 2 is by one first pipeline 7 and water sprayer 3
It is connected, described water sprayer 3 is provided with a suction inlet 8, with an increaser 9 below described water sprayer 3
Upper end be connected, described increaser 9 lower end is connected with diverter pipeline 5 by second pipe 10, institute
State diverter pipeline 5 to be connected with each fluid distributor 6 respectively；
The lower end of described increaser 9 is connected with moisture trap 4 also by one the 3rd pipeline 11, described
The top of moisture trap 4 is connected to second pipe 10, described gas-water separation by one the 4th pipeline 12
The lower section of device 4 connects one first outlet pipe 13；
One the 5th pipeline 14 it is also associated with between described first pipeline 7 and second pipe 10, described second
Connected on pipeline 10 each pipeline order be followed successively by from front to back the 3rd pipeline the 11, the 4th pipeline 12,
5th pipeline 14 and one second outlet pipe 15, described first pipeline 7, second pipe the 10, the 3rd are managed
On road the 11, the 4th pipeline the 12, the 5th pipeline the 14, first outlet pipe 13 and the second outlet pipe 15 right
First valve the 16, second valve the 17, the 3rd valve the 18, the 4th valve the 19, the 5th valve should be provided with
20, the 6th valve 21 and the 7th valve 22；
Each described fluid distributor 6 is fixed on bottom equipped with the filter tank of filter material layer, each described fluid distributor
Plural number filter cap 61 it is provided with on 6.
Emphasis refers to Fig. 2, and described filter cap 61 is hemispherical, and described filter cap 61 is evenly distributed with width
It it is the gap 611 of 0.25～0.45mm.
Gap 611 gross area in described whole filter cap 61 accounts for the 1% of filter tank bottom area.
Each described fluid distributor 6 is solid by the screw 621 on plural number stainless steel lathe dog 62 and clip both wings
It is scheduled on bottom filter tank, it is ensured that stable firm.
The other end of described first outlet pipe 13 and the second outlet pipe 15 all stretches in clear water reserviors 1.
The present invention can be to realize three kinds of modes of filter back washing:
1), during mixing wastewater with air backwash, the first valve 16 and the second valve 17 are opened, the 3rd valve 18,
4th valve the 19, the 5th valve the 20, the 7th valve 22 is closed.Water pump 2 extracts from clear water reserviors 1,
Forming high-velocity flow by water sprayer 3, current are changed by energy in water sprayer 3, form vacuum and bear
Pressure swabbing action, sucks air from suction inlet 8, forms mixing wastewater with air fluid, then passes through water sprayer
3 bottom increasers 9, are converted into high-pressure mixing fluid, then are sent into diverter pipeline 5 by second pipe 10.
Each fluid distributor 6 is all connected with diverter pipeline 5, makes mixed flow physical ability divide equally the multiple fluids of entrance and divides
Orchestration 6.Fluid distributor 6 uses PE material injection to process.Uniform plural number filter cap 61 on it,
Filter cap 61 hemisphere is labeled and is uniformly distributed the gap 611 that width is 0.25-0.45mm, total face, gap 611
Long-pending being about bottom filter tank the 1% of the gross area, backwash resistance is little.Fluid is entered by these fine gap
Filter material layer, carries out filtrate backwash.
2), during the independent backwash of air, the second valve the 17, the 5th valve the 20, the 7th valve 22 is closed,
Remaining valve wide open.Water pump 2 draws water, through water sprayer 3 formed fluid-mixing through the 3rd pipeline
11 enter moisture trap 4 carries out aqueous vapor separation, and water is by the first outlet pipe 13 times below moisture trap
It flow to clear water reserviors 1.Air is entered diverter by the 4th pipeline 12 being connected with moisture trap 4 top
Pipeline 5, is then tapped off into each fluid distributor 6, then is sprayed by filter cap 61, it is achieved air individually recoils
Wash.
3) during the independent backwash of water, first valve the 16, second valve the 17, the 4th valve the 19, the 7th
Valve 22 is closed, remaining standard-sized sheet, and water pump 2 draws water and directly enters diverter pipeline by the 5th pipeline 14
5, it is re-fed into fluid distributor 6, filter cap 61 sprays, it is achieved complete the independent backwash of water.
When filtering, the second valve the 17, the 4th valve the 19, the 5th valve 20 is closed, the 7th valve 22
Open.Cross drainage to be collected by filter cap, enter fluid distributor 6, subsequently into diverter pipeline 5,
Clear water reserviors 1 are entered by the second outlet pipe 15.
Present invention have the advantage that
1, the backwashed fluid dynamical system that water pump and water sprayer are constituted, saves aerodynamic offer and sets
Standby, reduce number of devices.
2, unique fluid dispensing arrangement, decreases the complexity of fluid distributor, and installation is convenient；
3, fluid distributor and filter cap are by PE material, are molded one-shot forming, and are fixed on bottom filter tank,
Make fluid distributor be prone to holding level, strengthen fluid distribution uniformity.
In a word, backwashing equipment of the present invention is simple, and the little fluid distributor of backwash energy consumption is easy for installation, stream
Body distributed uniform.
Although the foregoing describing the detailed description of the invention of the present invention, but it is familiar with the technology people of the art
Member should be appreciated that our described specific embodiment is merely exemplary rather than for this
The restriction of bright scope, those of ordinary skill in the art are in the equivalence made according to the spirit of the present invention
Modify and change, all should contain in the scope of the claimed protection of the present invention.
