Abstract
The invention publishes a washing method of multi-medium filter layer filtration pot regeneration eddy current, the characteristic is: When counterflushing, the filter material carries on inside pot out-circulate and at the same time also in the pot eddy current revolve, revolving through the pellet filter material drive the other materials to revolve, washing off the pollutant in the upside of the adsorb medium through revolving, dissolving the adsorption pollutant of the pellet material surface in the water through the revolving friction and draining away along with the counter-flashing water, the counter-purging method has the few water consumption, the good counter-flushing effect, the high system efficiency, and reliable,and can be widely used in the multi-medium filter filtration pot regeneration.
Description
The present invention relates to a kind of rinsing method of regenerated vortex for filtration pot with filtering layers in multiple media.
In oil and the chemical industry sewage disposal at the filtering tank of usefulness regeneration back-flushing method, all exist the problem of back washing strength height and backwash effect difference, as sandfiltration pot, double filtering filtering tank, multi-functional waste water purification device (98240142.6), multi-functional oilfield sewage filter (01202850.9), modified fiber ball filter (00230750) etc., to still can not satisfy the production needs by good recycle-water for water quality requirement after requiring the low and backwash of back washing strength.
Be head it off, the on-the-spot temperature that improves backwashing water, the method that prolongs backwashing time or more renew filtrate of adopting solves more, for this reason, have that backwashing time is long, the backwash water amount is big, change workload big, change filtrate contaminated environment, developing result difference and the blending rinsed problem of multiple medium filtrate and do not solve.
The objective of the invention is to provide a kind of multimedium filtering layer filtering tank regenerated vortex back-flushing method, to reduce back washing strength, filtering water after the minimizing backwash water yield, the raising backwash also solves multiple medium filtrate simultaneously effectively and mixes a flushing regenerating technique difficult problem.
For achieving the above object, technical scheme of the present invention is: will be divided into a plurality of filter medium intervals in the filtering tank, be divided into suspension coagulating layer, adsorpting aggregation layer, coarse filtration layer, middle filtering layer, fine filtering layer, smart filter course from top to bottom; Outside jar, be furnished with filtrate circulating pump and backwashing pump in addition.This multimedium filtering layer filtering tank regenerated vortex back-flushing method can make original multistage backwash regeneration become one-level backwash regeneration.
As a further improvement on the present invention, unidirectional backwash method and circulation filtrate method are integrated, in filtering tank, do not have to make under the agitating device condition of stirring multimedium filtrate in jar, to produce the eddy current rotation.
As of the present invention further the improvement again be, granule filter material carries out the inside and outside circulation time of jar, and filtrate is that tangent line is extracted out and tangent line is squeezed into and made jar granule filter material of interior backwash fluidisation produce eddy current in jar to rotate; Eddy current rotation by granule filter material drives other filtrate rotation, by rotation the pendulum of the pollutant in its adsorbing medium is washed off, and is by the rotation friction that granule filter material surface absorption pollutant is soluble in water, discharges with backwashing water.This kind method has solved the technical barrier of multimedium filtering layer filtering tank media regeneration.
The invention has the advantages that multimedium filtering layer filtering tank regenerated vortex back-flushing method is simple, water consumption is few, effective, simplify the sewage disposal flow process, reduced construction investment and operating cost, make things convenient for field management, alleviated labor strength, human body there is not injury, environmentally safe.For filtering tank regeneration provides a kind of new eddy current purging method.
Rinsing method of regenerated vortex for filtration pot with filtering layers in multiple media of the present invention the steps include:
(1) starts the backwashing pump backwash,, its absorption greasy dirt is squeezed earlier with the adsorbing medium reverse compression in coagulating layer and the adsorpting aggregation layer.
(2) backwash normal after, restart the granule filter material that the filtrate circulating pump plays backwash fluidisation in the tank body and carry out the interior outer circulation of jar.
(3) granule filter material also produces the eddy current rotation in jar in the outer circulation in jar.
(4) other filtrate of eddy current rotation drive of jar endoparticle filtrate rotates in jar, by rotation the pendulum of the pollutant in its adsorbing medium is washed off, by rotation friction grain filter material surface absorption pollutant is soluble in water, discharge with backwashing water, finish the regeneration of multimedium filtering layer filtering tank.
In the said step (1), carry out backwash with the suspension ball in coagulating layer and the adsorpting aggregation layer, coarse media foam sponge, fiber and hair fabric reverse compression, its adsorbed oil is squeezed with backwashing pump.
In the said step (2), restarting the backwash that circulates of filtrate circulating pump after backwash is normal, is that the granule filter material that backwash fluidisation in the tank body rises is carried out the interior outer circulation of jar.
In the said step (3), granule filter material carries out the inside and outside circulation time of jar, adopts with the tank body tangent line is extracted out and the tank body tangent line is squeezed into method to make filtrate produce in jar that eddy current rotates.
In the said step (4), the eddy current rotation of jar endoparticle filtrate drives other filtrate rotation, by rotation the pollutant in its adsorbing medium pendulum is washed off, by the rotation friction granule filter material surface absorption pollutant is soluble in water, discharge with backwashing water and to finish.
Rinsing method of regenerated vortex for filtration pot with filtering layers in multiple media is characterized in that: filtrate carries out outer circulation also generation eddy current rotation in jar of filtrate simultaneously in the jar during backwash, finish multimedium filtering layer filtering tank flushing regeneration by the rotation of filtrate in jar, this method backwash effect is good, water and electric saving, efficient energy-saving, can be widely used in having the regeneration flushing of granulated filtering layer filtering tank.
Claims (2)
1, a kind of rinsing method of regenerated vortex for filtration pot with filtering layers in multiple media, it is characterized in that: during backwash, filtrate carries out outer circulation also generation eddy current rotation in jar of filtrate simultaneously in the jar, drive the rotation of other filtrate by the rotation of granule filter material in jar and finish multimedium filtering layer filtering tank flushing regeneration, its method is made up of following steps:
