Abstract
The utility model relates to a resin high-position back washing apparatus for a desalted water treatment system, which comprises a back washing tower. The utility model is characterized in that the resin outlet and inlet of a cation bed and the resin outlet and inlet of an anion bed are respectively communicated with the bottom of the back washing tower by resin pipelines; an outlet at the bottom of the back washing tower is higher than the resin tops of the cation bed and the anion bed; the top of the back washing tower is provided with a drainage pipe and a connecting raw water pipeline. The utility model has the advantages that the resin which is back washed can be easily and fully shifted back to exchange columns, avoiding the phenomenon of wall corners; a set of desalted water treatment apparatus only needs to be provided with one back washing tower, and lots of water for back washing can be saved.
Description
The utility model relates to the backwash device of resin in desalted water processing system sun bed and the cloudy bed.
Floating bed (positive and cloudy bed) Inlet and outlet water pressure reduction increase, the exchange column water production rate obviously reduces, and shows that interior broken resin of resin layer and dirt gather, and the reply resin carries out backwash, to recover the service ability of floating bed.
At present, domestic resin backwash technology mainly contains following three kinds:
(1) water-gas backwash method:
A. shift out resin: water-gas backwash method need all be moved to resin by exchange column carries out backwash in the purge tank.
B. drain the water away: make the interior ponding of purge tank drain into the above 100mm of resin aspect place.
C. air backwash
D. backwash: with former water resin is carried out backwash, with resin layer expansion 60～100% control backwash intensity.
E. retract resin: resin in the purge tank is moved back in the exchange column with clear water.
(2) the backwash technology of bleeding in the body:
A. drain the water away: ponding in the post is drained into 50～100mm place more than the resin aspect.
B. open the resin valve: make and form resin channels between lower shell.
C. the scouring of bleeding: available water sprayer or vacuum pump are bled, rate of air sucked in required be about 10 liters/meter 2 seconds, during scouring, keep interior vacuum tightness 300～400mmHg post.
D. water backwash: same water-gas is cleaned the operation of method.
E. resin lands: close into water, the resin free-falling is all fallen in the cylindrical shell.
F. wash upper shell: by the water inlet of upper shell top annular void channels, the resin Archon of flushing upper shell inwall makes it to fall into lower shell.
G. close the resin valve, prepare regeneration.
(3) water cleaning process:
A, shift out resin: 50% resin is moved in the purge tank.
B, backwash:
C, retract resin, prepare regeneration.
More than three kinds of technologies, because of exchange column and backwash device all at grade, after so ubiquitous major defect is the resin backwash, all can not return interchanger (" wall angle " phenomenon) fully, therefore, yin, yang resin backwash device can not be shared and must be set up separately, has promptly increased construction investment, need waste a large amount of backwash waters again.
The purpose of this utility model provides the high-order backwash device of a kind of desalted water processing system resin, fundamentally solves " wall angle " phenomenon that exists in the resin backwash, saves the backwash water.
The high-order backwash device of desalted water processing system resin of the present utility model, comprise backwashing tower, the resin gangway that it is characterized in that sun bed and cloudy bed is communicated with the bottom of backwashing tower by resin line respectively, the outlet at bottom of backwashing tower is higher than the resin top of sun bed and cloudy bed, and the top of backwashing tower is provided with water shoot and connects raw water pipeline.
What the utility model adopted is water cleaning process, the same prior art of processing step.A high position is provided with the backwash device, makes resin retract exchange column at an easy rate by resin line, has avoided " wall angle " phenomenon, as long as a covering device is provided with a backwashing tower, just can satisfy service requirements, and can save a large amount of backwash waters.
Backwashing tower preferably bottom is conical, and top is cylindrical.
The backwashing tower bottom preferably is higher than the resin top of sun bed and cloudy bed more than 0.5 meter.
Below in conjunction with the embodiment description of drawings:
Fig. 1 is a structural representation of the present utility model
Among the figure: 1 backwashing tower, 2 sun beds, 3 cloudy bed 4 water shoots 5 former water flushing line 6 resin line
Sun bed and cloudy bed adopt two chambers floating bed.Backwashing tower bottom is higher than on the floating bed chamber resin more than 0.5 meter.Backwashing tower top is cylindrical, and the bottom is the pyramid type that 0.3% gradient is arranged, and the top is provided with water shoot 4 and former water flushing line 5.Sun bed and cloudy resin line 6 by separately respectively are connected with the bottom of backwashing tower.Enter and exit in order to help resin, resin turnover inlet tube preferably adopts eccentric reducer.
Press water cleaning process, when cleaning sun bed resin, the resin of following chamber 7 is moved on in the backwashing tower by resin line 6, pass through former water rinse resin from sun bed bottom, after reaching requirement, stop backwash, the water in the backwashing tower is got rid of by water shoot, by former water flushing line 5 waters resin is moved back in the sun bed along resin line again, prepares regeneration.And then the resin that will go up the chamber carries out backwash in the same way.The backwash of cloudy bed resin is same.
Advantage of the present utility model:
Resin can be retracted exchange column after by backwash at an easy rate fully, has avoided " wall angle " phenomenon, a cover desalted water As long as treating apparatus arranges a backwashing tower, just can satisfy instructions for use, and can save a large amount of backwash waters. Overcome Prior art cation bed and anion bed backwashing tower need to be set separately, and the deficiency of " wall angle " phenomenon is arranged.
Claims (3)
1, the high-order backwash device of a kind of desalted water processing system resin, comprise backwashing tower, the resin gangway that it is characterized in that sun bed and cloudy bed is communicated with the bottom of backwashing tower by resin line respectively, the outlet at bottom of backwashing tower is higher than the resin top of sun bed and cloudy bed, and the top of backwashing tower is provided with water shoot and connects raw water pipeline.
2, backwash device according to claim 1 is characterized in that the backwashing tower bottom for conical, and top is cylindrical.
3, backwash device according to claim 1 is characterized in that the backwashing tower bottom is higher than the resin top of sun bed and cloudy bed more than 0.5 meter.
