(21), two outlet pipelines (19), two outlet valves (20), outlet pipeline (22), electrically-controlled valve (29) are entered
Enter auxiliary filtering tank (30), then return to polluter by back-water valve (BWV) (31) after auxiliary filtration pellet (37) is filtered
(1), in, circulation is formed.This process is backwash stage.
The backwash time opens to electrically-controlled valve (26), electrically-controlled valve (29) is closed, and high-pressure hydraulic pump (6) is automatically controlled
The control software of case (28) transfers low cruise under controlling, enter filtration stage.Now air pump (32) opens
Dynamic, upper inlet valve (34), the liquid in auxiliary filtering tank (30) is under the influence of air pressure by back-water valve (BWV) (31)
Return in polluter (1), so that the impurity drying kinetics that auxiliary filtration pellet (37) retains, set and be dried
Time is to back-water valve (BWV) (31), upper inlet valve (34), closedown, lower inlet valve (33), blowoff valve (35) simultaneously
Open the impurity auxiliary filtration pellet (37) retained to discharge from blowoff line (36) in a dry form, during blowdown
Between to air pump (32), lower inlet valve (33), blowoff valve (35) close, the first duty terminates.
When setting filtration time to forwarding the second duty to.
Second duty: high-pressure hydraulic pump (6) is transported at a high speed under the control software of electric cabinet (28) controls
OK, by the liquid in polluter (1) by pipeline (5) extract out, then through outlet pipeline (9) with help oxygen device
(7) oxygen injected is opened by two water intaking valves (18), two inlet pipelines (17), is entered two cloth water cavities
(21), columnar liquid is distributed whole intracavity, through upper wire orifice plate (23) in two cloth water cavities (21)
Enter two filter chambers (25), after being filtered by two filtrations pellet (24) in two filter chambers (25), enter storage
Water cavity (3), a portion impurity is trapped within two filtration pellets (24), the liquid in water storage cavity (3)
Body filters pellet (8) by a filter chamber (10) one the most from bottom to top, due to two mistakes
Filter pellet (24) with one filter pellet (8) filtering material identical, therefore one filtration pellet (8) now without
Big filter effect, but the impurity retaining the first duty plays backwash effect, the pollution liquid warp that backwash goes out
Cross a cloth water cavity (10) a, outlet pipeline (15), an outlet valve (16), outlet pipeline (22), automatically controlled
Valve (29) enters auxiliary filtering tank (30), then by back-water valve (BWV) (31) after auxiliary filtration pellet (37) is filtered
Return to, in polluter (1), form circulation.This process is backwash stage.
The backwash time arrives, and electrically-controlled valve (26) is opened, electrically-controlled valve (29) is closed, and high-pressure hydraulic pump (6) is at electricity
The control software of control case (28) transfers low cruise under controlling, enter filtration stage.Now air pump (32)
Startup, upper inlet valve (34), the liquid in auxiliary filtering tank (30) passes through back-water valve (BWV) under the influence of air pressure
(31) return in polluter (1), so that the impurity drying kinetics that auxiliary filtration pellet (37) retains, if
Determine drying time to back-water valve (BWV) (31), upper inlet valve (34), close, simultaneously lower inlet valve (33), row
Dirty valve (35) is opened the impurity auxiliary filtration pellet (37) retained and is arranged from blowoff line (36) in a dry form
Going out, blowing time to air pump (32), lower inlet valve (33), blowoff valve (35) are closed, the second work shape
State terminates.
When setting filtration time to forwarding the first duty to.
Being not difficult to find out that above-mentioned first duty is the backwash to the second duty, the second duty is right
The backwash of the first duty.
Being not difficult to find out that above-mentioned backwash time high-pressure hydraulic pump high-speed cruising enhances backwash effect, during filtration, the time is again
Transfer low cruise to thus ensure that filtering accuracy.
It is not difficult to find out that above-mentioned backwash is to carry out in equipment runs, was appropriately arranged with for two duty conversion times,
Filtrate can be avoided the occurrence of harden phenomenon, therefore without high-power mixing wastewater with air backwash, thus save mass energy
Achieve the purpose of reduction of discharging.
Being not difficult to find out that above-mentioned impurity is to discharge in a dried form, liquid is in operation and is not lost.
It is not difficult to find out that aforesaid liquid filter type is continuously generated with the urine of biological kidney, the filtration mechanism that interval separates out
Identical, it is genuine equipment kidney.
It is not difficult to find out that the incrustation scale that high-temperature water is produced by above-mentioned filter type can be discharged in time, it is achieved physics softens water
Purpose.
In sum, by the on-line filtration to liquid, allow the liquid to consistently online recycling and reach joint
The effect that can reduce discharging.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
