Description
Technical field:
The utility model belongs to water treatment field, particularly a kind of municipal administration and industrial quality purifying device for water.
Technical background:
Filtration is an important water treatment technology, and continuous and Reverse Washing Sand Filter is a kind of sand filtering device of continuously-running.The difference of it and conventional filter is that backwash need not to interrupt filter process, filters with backwash and carries out simultaneously, has realized continuous filtration, and filtering layer cleans automatically continuously and upgrades.Its unique design theory is in developed country's extensive use, and foreign environmental protection company is China's popularization also, as the dynamic sand filtration machine that the new water utilities in Eurasia is promoted in China, and the efficient stream sand filter that american wheat king environmental protection energy energy group promotes in China.
The continuous and Reverse Washing Sand Filter operation principle: the work of continuous and Reverse Washing Sand Filter comprises filters and two relatively independent processes of carrying out simultaneously again of backwash, sewage at first is distributed in the filtering layer of filter bottom equably by the water inlet distributor that is installed in the filter bottom, sewage passes filter bed and upwards flows, dirt is intercepted and captured by filtrate in the uphill process, and the clear water after the filtration is collected by the downflow weir of filter top and discharged.Contaminated filtrate rises to the cleaning device at top from the sand filtration motor spindle with air lift, filtration clear water about 5%-10% is taken the pollutant rinsing in the diffuser out of as backwash water, filtrate after the cleaning is then sent back to above the filter bed again, enters next filtration cycle.Realized filtering layer continuous filtration, automatically the process of upgrading.On behalf of manufacturer, it have
The DynaSand filter of Parkson company
The DynaSand filter of Vexamus company,
The CONTIFLOW of Huber company
Sandfilter CFSF
The Continual Backwash Filter. of Technasand company
The Continual Backwash Filter of Unidro company
The ASTRASAND of Aquabio Ltd company
The moving bed up-flow Sandflo filter. of YUCHEON ENVIR company
The defective of these equipment is: 1, handle the former water of high turbidity, the filter sand cleaning performance is poor, and filter sand is unclean, and the backwash water yield is big, the delivery turbidity height, and equipment can not normally move.2, Noise of Air Compressor is big.The jet system complexity.
Summary of the invention:
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and provide a kind of simple in structure, the backwash ability big, can handle high turbidity water inlet, improve the continuous filtration hydrotreater of effluent quality.
The technical solution adopted in the utility model is: this continuous filtration hydrotreater, comprise conical shell, sand pump, hydrocyclone, sand-washing device, connecting pipe, be fixed with injection well downhole flow regulator in the conical shell, cloth sand plate, and be placed with filter sand, injection well downhole flow regulator connects with the former water water inlet pipe of outside, the conical shell lower end is by going out sandpipe and the sand pump input connects, the sand pump output connects hydrocyclone by the sediment transport pipe, the hydrocyclone top connects the center discharge pipeline, the hydrocyclone bottom connects sand-washing device, sand-washing device places the conical shell internal upper part, and conical shell top is equipped with downflow weir and outlet pipe.
In the technique scheme, the sand-washing device top connects the sandpipe that of conical shell lower end by circulation pipe, control valve.
In the technique scheme, sand-washing device is the rectangle cylindrical shell of a upper and lower opening.
Compared with prior art, advantage applies of the present invention following several aspect:
1, this continuous filter has adopted the combination of sand pump and hydrocyclone that filter sand is carried out the desliming operation, has greatly strengthened the washed-out sand function of filter.Expanded the scope of application of filter, made filter can directly handle the former water of high turbidity.
2, adopt the labyrinth type sand-washing device that filter sand is carried out secondary cleaning, make the cleaner of filter sand cleaning.Reduce the filter delivery turbidity simultaneously, improved effluent quality.
3, sand-washing device water outlet secondary is utilized,, reduced the washed-out sand water as the dilution water of filter sand.Promptly reduced equipment from water.
4, adopt sand pump to replace air compressor, reduce the noise of operation, and make control system simpler.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the figure: 1, water inlet pipe; 2, injection well downhole flow regulator; 3, cloth sand plate; 4, filter sand; 5, sand pump; 6, sandline; 7, hydrocyclone; 8, discharge pipeline; 9, sand-washing device; 10, circulation pipe; 11, control valve; 12, downflow weir; 13, outlet pipe; 14, go out sandpipe; 15 housings.
The specific embodiment:
Referring to Fig. 1, the utility model comprises conical shell 15, sand pump 5, hydrocyclone 7, sand-washing device 9, connecting pipe, be fixed with injection well downhole flow regulator 2 in the conical shell 15, cloth sand plate 3, and be placed with filter sand 4, injection well downhole flow regulator 2 connects with the former water water inlet pipe 1 of outside, conical shell 15 lower ends connect with sand pump 5 inputs by going out sandpipe 14, sand pump 5 outputs connect hydrocyclone 7 by sediment transport pipe 6, hydrocyclone 7 tops connect center discharge pipeline 8, hydrocyclone 7 bottoms connect sand-washing device 9, sand-washing device 9 places conical shell 15 internal upper parts, and conical shell 15 tops are equipped with downflow weir 12 and outlet pipe 13.Sand-washing device 9 tops go out sandpipe 14 by what circulation pipe 10, control valve 11 connected conical shells 15 lower ends.Sand-washing device 9 is the rectangle cylindrical shell of a upper and lower opening.
Operation principle: the former water behind the dosing coagulant enters filtering layer by water inlet pipe 1 through injection well downhole flow regulator 2, upwards flows through filter sand 4, and the polluter of current in uphill process held back by filter sand, and the clear water after the filtration is flowed out by clear water pipe 13 by downflow weir 12.When filtering, the contaminated filter sand in bottom flows in the conical hopper of filter below by cloth sand plate 3, sand pump 5 is come the dirty sand suction in the funnel by pipeline 14, the recycle-water of coming by reuse water pipe 10 in addition that suction is simultaneously come, sand is sent into hydrocyclone 7 with after water mixes through sediment transport pipeline 6, and dirty sand and water high speed hydrocyclone 7 in is rotated, under centrifugal action, near the barrel of heavy sand grains migration.The mud that the proportion that sand grain surface sticks is little separates with sand grains, move to the hydrocyclone center with current, final slurry is discharged by the center discharge pipeline 8 at hydrocyclone top, and the filter sand after the desliming falls along pool wall and flows into sand-washing device 9 by the hydrocyclone bottom.Sand-washing device 9 is a upper and lower opening rectangle cylindrical shell, and cylinder inboard wall is equipped with staggered blade, and sand-washing device is installed in the water of filter Chi Ding.Filter sand after the desliming flows into sand-washing device, under the gravity effect, flows in the pond downwards along staggered blade order in the sand-washing device.Water in the sand-washing device blade that is staggered in water-head effect lower edge upwards flows, the two counter motion of sand and water, and clear water carries out secondary cleaning to filter sand, last water flows to the sand-washing device top, enter circulation pipe 10, again through control valve 11, the dirty sand that falls under awl enters sand pump.The filter sand of cleaning is fallen the filter bed top, and slowly falls with filter bed, enters next circulation.
