After end-of-job, discharge the liquid of reverse blowing with energy accumulator filter interior residual.
Refering to Fig. 6, the filtration of the reverse blowing with energy accumulator filter of the present embodiment and filter regeneration method have following steps:
S100, air nature filling process.Before filtration, air fills the inside of reverse blowing with energy accumulator filter, i.e. air naturally
Naturally enter and fill stoste space 220 and cleaner liquid space 230.
Owing to, before filter uses, it must be to close that stoste enters valve 300, opens filter cake dump valve 500, can make
Air can enter and be full of rapidly the inner space of filter naturally.When filter is started working, close filter cake dump valve
500, make the air seal entering to stoste space 220 and cleaner liquid space 230 in the inside of filter.
S200, filters accumulation of energy process.Now, stoste progresses into the stoste space 220 of reverse blowing with energy accumulator filter, after filtration
Forming cleaner liquid, the air of entrance naturally is gradually compressed to accumulator space by cleaner liquid, now has the in cleaner liquid space 230
The pressure that one pressure P1, i.e. cleaner liquid discharge.Persistently carry out being formed on filter screen 210 filter cake 240 along with filtering.To certainly during this
So air has carried out first compression accumulation of energy.
Specifically, opening stoste and enter valve 300 and cleaner liquid dump valve 400, stoste is passed through under the drive of centrifugal pump 100
Stoste enters valve 300 and enters stoste space 220, and stoste enters cleaner liquid space 230, filter through the cleaner liquid that screen pack 210 is formed
The first cleaner liquid space 231 and the second cleaner liquid space 232 gradually filled by clear liquid, and is discharged by cleaner liquid dump valve 400.This
The top that air in body 200 is compressed and is sealed in the second cleaner liquid space 232.The filter cake 240 formed accumulates on stoste
Space 220 is also attached on filter screen 210.
As shown in Figure 4, after filter work, the first cleaner liquid space 231 and bottom in the second cleaner liquid space 232 in figure
(the horizontal dotted portion of diagram) is liquid filled, the second cleaner liquid space 232 that the air of closing is compressed and accumulates in
Top space in (the atomization point part of diagram).There is pressure reduction before and after filter cake 210, its numerical value leads to for promoting fluid
The resistance formed when screen pack 210 and filter cake 240.
After filter process proceeds to certain time, due to the enlarged in thickness of filter cake 240, fluid running resistance increases, i.e.
Can cause the increase of filtration resistance, the degree of increase can judge by measuring water pump head, if the solid formation in liquid
Few, then the filter process sustainable longer time, on the contrary may duration can reduce.The pressure of liquid before and after filter cake 210
When difference reaches the numerical value realizing setting, certain thickness that filter cake 240 has accumulated is described, follow-up filter process can be affected
Speed, needs blowback slag dumping.
S300, recompresses accumulation of energy process.First in cleaner liquid space 230 is made to press by the continuous running of centrifugal pump 100
Power P1 rises to the second pressure P2, and the air being compressed in accumulator space is once again by compress energy storage.
To this end, be first shut off cleaner liquid dump valve 400, then the flow of system will reduce to zero, and a part of stoste continues through
Stoste enters valve 300 and enters stoste space 220, and the pressure of centrifugal pump 100 will increase to its maximum pressure P2, then filtering liquid air
Between 230 pressure be also up to P2 (the second the most above-mentioned pressure), will be compressed once again as it is shown in figure 5, be now closed air,
Compressed-air actuated pressure at accumulator space also can reach P2.
Accumulation of energy process before slag dumping is the characteristic utilizing centrifugal pump 100 self, and when its flow reduces, it exports pressure head meeting
Increasing, when flow is reduced to 0, pump still can run well, and pressure head can reach maximum, and now the power output of pump can subtract
To minimum.
Centrifugal pump is the power supplying apparatus that the promotion stoste that used of the present embodiment enters filter, if do not use from
Heart pump, but other power supply device promotes stoste, the air pressure being closed in filter interior will rise to operating pressure.
S400, blowback tapping process.Now, open filter cake dump valve 500, then the pressure within stoste space 220 is rapid
Be kept to identical with outside atmospheric pressure P0, be i.e. down to P0 by P2, thus in the both sides of filter screen, the first cleaner liquid space 231 He
A pressure differential, pressure reduction △ P=P2-P0 is formed between stoste space 220.Under the driving of this pressure reduction △ P, at the of filter
The cleaner liquid that one cleaner liquid space 231 and the second cleaner liquid space 232 are retained by reversely from the outer side inflow filter cake of filter screen 210
Flow to stoste space 220 in the inner side at 240 places, i.e. cleaner liquid.The reverse flow of cleaner liquid is at whole filter screen 210 everywhere
Occurring simultaneously, thus will be attached to the filter cake 240 on filter screen 210 and remove from filter screen 210, the filter cake of fluid and peeling is at gravity
The lower outside draining into rapidly filter from filter cake dump valve 500 of effect.
When filter cake 240 is discharged from filter cake dump valve 300, the back side of filter screen 210 can not be made (i.e. in the face of cleaner liquid space
The one side of 230) pressure be P0 in instantaneous attenuating.During compressed air expands, gas persistently promotes filter interior
Liquid carry filter cake 240 and discharge, until internal liquid emptying.When pressure reduction △ P is zero, complete the cleaning of a filter cake 240
Process.
Centrifugal pump 100 is more than 1.5 times of the operating pressure of normal work at the null maximum pressure of flow, due to
Before blowback, take full advantage of the feature of centrifugal pump, improve the pressure of air energy-storage, thus improve the flow velocity of blowback fluid,
And then improve the effect of blowback discharging.
S500, restarting procedure.Close filter cake dump valve 500, open stoste and enter valve 300 and cleaner liquid dump valve
400, enter the filter process of S200, filtration proceeds.
Filter cake dump valve 500 no longer has liquid to flow out, i.e. explanation tapping process terminates, and can enter filter process, conversion
Time, first close filter cake dump valve 500, i.e. define an airtight space in filter interior, be then turned on cleaner liquid dump valve
400, i.e. to connect the passage that cleaner liquid is external, be now then turned on stoste and enter valve 300, filter process i.e. can proceed with.
The working cycles of the reverse blowing with energy accumulator filter of the present invention is that filtration-accumulation of energy-deslagging-filtration is carried out successively, more than
In the described different course of work, the keying of valve and in process is changed the keying order of valve see table and (use centrifugal
Pump provides power, has secondary accumulation of energy process).
It should be noted that, power supplying apparatus is set to centrifugal pump by the present embodiment, be to utilize centrifugal pump itself
Characteristic, strengthen blowback effect.When filter normally works, the compressed-air actuated pressure of accumulator space is P1, when cleaner liquid is discharged
After valve 400 is closed, the pressure of accumulator space can be further increased to P2, during blowback discharging, closes stoste liquid feed valve 300, beats
Drive filter cake dump valve 500, then the pressure in stoste space reduces to rapidly atmospheric pressure P0, the cleaner liquid of storage in cleaner liquid space
