The utility model compared with prior art has the following advantages and beneficial effect: the back taper filter course that adopts double-deck back taper filter screen and Sandwich filling thereof to have three layers of different medium filtrate to form, not only greatly increase filter area, and then the raising rate of filtration and contamination capacity, coordinate the injection water-out manners of the discoid Water outlet spray head of water-locator simultaneously, guarantee fully contacting of pending water and filter course, effectively remove Coal Gas Washing Cycling Water suspension and the Fe and Mn that exceeds standard.In utility model, lower floor's back taper filter course bottom welding has cylindrical screen pack, and cylinder type filter net outlet at bottom is communicated with sewage draining exit, in filter process, due to mobility and the Action of Gravity Field of water, hard particles dirt can enter in cylinder type filter net to be accumulated, play dirt crown_interception, thereby effectively prevent that the filtrate of filter course from hardening, facilitate periodic maintenance cleaning simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, the utility model comprises filter tank body 1, tank body feet 2, venthole 3, filtered water outlet 12, filter tank body 1 top arranges water inlet 4, water inlet 4 is also backwash delivery port, water inlet 4 upper end exit surfaces are external screw thread, water inlet 4 lower ends arrange water-locator 5, water-locator 5 bodys adopt stainless steel tube to make, body bottom is connected with discoid Water outlet spray head 14 by internal thread securing member 13, and some regularly arranged circular apopores are set on the water outlet panel of discoid Water outlet spray head 14; Filter tank body 1 middle part is welded with upper and lower two-layer annular brace bar 6, on annular brace bar 6, symmetry is opened four holes respectively, utilize on annular brace bar 6 perforate and the locking nut upper and lower two-layer back taper filter screen 7 that is locked respectively, a cylinder type filter net 8 is welded in lower floor's back taper filter screen 7 bottoms; Upper and lower two-layer back taper filter screen 7 outsides, with one deck filter cloth 15, are filled with three layers of different medium filtrate 9 between upper and lower two-layer back taper filter screen 7 interlayers; Three layers of different medium filtrate 9 are by bottom manganese sand filtering material filtrate, middle level porous ceramic filter material, and upper strata long fibre filtrate forms; Filter tank body 1 place of bottom centre arranges sewage draining exit 10, and sewage draining exit 10 is communicated with cylinder type filter net 8 bottoms, and filter tank body 1 two bottom sides face is symmetrical arranged respectively backwash water inlet 11.Sewage draining exit 10 diameters of filter tank body bottom are less than the pipe diameter of water inlet 4, prevent that the excessive filtrate that causes of backwash impulse force runs off.
Filter tank body 1, upper and lower two-layer back taper filter screen 7, cylinder type filter net 8, discoid Water outlet spray head 14 concentrics, and the bottom surface diameter of upper strata back taper filter screen 7 is identical with discoid Water outlet spray head 14 water outlet panel diameters, has guaranteed that water distribution is even.
When filtration operation, close sewage draining exit 10 and backwash water inlet 11, pending water is entered by water inlet 4, arrive upper strata stainless steel back taper filter screen 7 through water-locator 5 water distribution uniformities, the filter cloth 15 of making through nonwoven and upper strata stainless steel back taper filter screen 7 are held back after major diameter particle, former water fully contacts in three layers of different medium filtrate 9, realizes and effectively removes Coal Gas Washing Cycling Water suspension and the Fe and Mn that exceeds standard.The filter cloth 15 that the water purifying through three layers of different medium filtrate 9 is made through lower floor's stainless steel back taper filter screen 7, nonwoven and cylinder type filter net 8 fall into tank body 1 bottom and deposit to after certain water level, discharge from filtered water outlet 12.
Wherein, upper and lower two-layer back taper filter screen 7 adopts respectively the stainless steel twill weave filter screen of braiding lines opposite direction to make, on upper strata back taper filter screen upper surface and lower floor's back taper filter screen lower surface, make respectively layer of non-woven fabric filter cloth 15 simultaneously, further improve screen pack mesh density, not only prevent that filtrate runs off, and play the supplementary filtration of dirt second interception.Back taper filter course is due to mobility and the Action of Gravity Field of water, and particulate dirt enters cylinder type filter net 8 and accumulates.Cylinder type filter net 8 plays buffering crown_interception, effectively prevents that the filtrate of filter course from hardening, and has greatly improved filter efficiency, and cylinder type filter net 8 bottoms are communicated with sewage draining exit 10, facilitates periodic maintenance cleaning.
When backsurging operation, close venthole 3 and filtered water outlet 12, first open sewage draining exit 10 and clean cylinder type filter net 8 and tank body 1 impurities at bottom.Because water inlet 4 is also that backwash delivery port and upper end exit surface are external screw thread, be convenient for changing connecting pipe, be connected to pollution discharge pond therefore water inlet 4 places are replaced with to blow-off line before backsurging operation, after pipeline is changed, open backwash water inlet booster pump and be symmetrical arranged backwash water inlet 11 to the interior injection pressure water of tank body 1 by filter tank body 1 two bottom sides face simultaneously, in tank body, be filled with a certain amount of Compressed Gas by sewage draining exit 10 simultaneously, strengthen three layers of different medium filtrate 9 disturbance in filter course, and because filtrate voidage in back taper filtering layer structure is along filter height distribution gradient, filtrate is difficult for hardening, when backwash under certain backwashing pressure water and Compressed Gas effect time, be very easy to make the particle impurity held back in filter course loosening and along with press water is rinsed, reach the object that improves backwash cleannes and the water-saving that saves time.
