Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in Figure 1:
For a filtration unit for Circulating water effluent Water Sproading, comprise filtration barrel body 1; The top of described filtration barrel body 1 has water-in 2, the water inlet pipe be connected is provided with water intaking valve 21 with water-in 2; Water outlet 3 and backwash water-in 4 is had bottom the bucket wall of described filtration barrel body 1; Described water outlet 3 connects on the rising pipe that extends and is provided with outlet valve 31; Described backwash water-in 4 connects on the water inlet pipe that extends and is provided with backwash water intaking valve 41 and backwash water pump 42 successively; The bucket wall top of described filtration barrel body 1 has backwash water outlet 5, and backwash water outlet 5 and water outlet 3, backwash water-in 4 are staggeredly located; Described backwash water outlet 5 connects on the rising pipe that extends and is provided with backwash outlet valve 51; The bottom of described filtration barrel body 1 has backwash sewage draining exit 6, and backwash sewage draining exit 6 connects on the blow-off pipe that extends and is provided with backwash wash water valve 61; Be provided with three metafiltration layers in described filtration staving 1, be respectively filter screen 7, filter cloth 8 and HVM film 9 from top to bottom; Described filtering layer is the circular filtering layer be made up of two semicircle filtering layers; The radius of described semicircle filtering layer is identical with filtration barrel body 1 radius; Support fixing between described two semicircle filtering layers and filtration barrel body 1 by Pneumatic extension arm 10; The aperture of described filter screen 7 is 5-8mm, and the aperture of filter cloth 8 is the aperture of 0.1-1mm, HVM film 9 is 0.22-0.5 μm.
During filtration work: open air pump control Pneumatic extension arm 10 and stretch, 6 semicircle filtering layers are combined as 3 circular filtering layers.Close backwash outlet valve 51, backwash water intaking valve 41, backwash water pump 42, backwash wash water valve 61, open water intaking valve 21 and outlet valve 31.Wastewater Form Circulating Cooling Water flows into from water-in 2, from top to down successively through filter screen 7, filter cloth 8 and HVM film 9 three metafiltration layer, impurity in Wastewater Form Circulating Cooling Water respectively by the different filtering layer of these three layers of pore sizes to filtering out, it is stand-by that Wastewater Form Circulating Cooling Water finally flows into clean water basin from water outlet 3.
During backwash work: after filtering for a long time, filtering layer constantly retains suspended substance, causes the resistance of filtering layer to increase gradually, causes the pore plugging of filtering layer.Now, just need to carry out backwash to filtering layer.Close water intaking valve 21 and outlet valve 31, open backwash water intaking valve 41 and backwash outlet valve 51, flow into the effect of the recirculated water in clean water basin by backwash water pump 42, enter from backwash water-in 4.Circulating water flow carries out backwash to three metafiltration layers from below to up, finally flows out in Wastewater Form Circulating Cooling Water pond to be filtered from the backwash water outlet 5 on filtration barrel body 1 barrel of wall top.After flushing terminates, close backwash water pump 42, backwash water water intaking valve 41 and backwash water outlet valve 51, open backwash wash water valve 61.Booster air pump controls Pneumatic extension arm 10 and retracts, and filtering layer is turned down.Impurity on filtering layer flows down with current, flows out from backwash sewage draining exit 6.
The utility model not only can be filtered Wastewater Form Circulating Cooling Water by three metafiltration layers, also can carry out backwash to filtration unit simultaneously.And anti-scouring water just uses the recirculated water filtered out, to reach water-saving object.Draw data through actual production, this device can be economized on water 30m
3/ h.Meanwhile, to the high efficiency filter of Wastewater Form Circulating Cooling Water, decrease the blowdown flow rate of recirculated water, decrease the interpolation of recirculated water medicament, decrease recirculated water pre-treatment expense.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
