Description
Technical field
The present invention relates to mixed bed equipment technical field, more particularly to one kind can reduce the loss of mixed bed regenerating resin
Equipment.
Background technique
Mixed bed is the abbreviation of hybrid ionic exchange column, is for equipment designed by ion exchange technique.So-called mixed bed, just
It is that a certain proportion of cationic, anionic exchange resin is mixed loaded in same switch, the ion in fluid is handed over
It changes, remove.As shown in Figure 1, mixed bed generally comprises water inlet, inlet valve, upper valve, exhaust valve, upper water distributing plate, alkali-feeding valve, tree
Rouge loading port, middle valve, middle row mouth, acid inlet valve, resin discharge outlet, lower water distributing plate, just washing drain valve, discharge outlet, water outlet and
Outlet valve etc..Domestic mixed bed treatment process main feature is embodied in resin separation regeneration technology, when mixed bed produces water through examining not
When qualified, regeneration treatment must be carried out to it, regeneration method is Synchronos method regeneration.
Mixed bed regeneration step is usual are as follows: 1) prepares before regeneration: checking that failure each valve of mixed bed is fastened；Regenerate water tank Gao Shui
Position, mixed bed acid, alkali batch meter liquid level are high；Primary demineralixation system normal operation, compressed air is sufficient, and prepares to use with long contact of value
Gas；The normal operation inputs such as pressure gauge, flowmeter, thermometer；2) it is layered: opening backwash inlet valve (HV5917A/B/C), upper row
Valve (HV5915A/B/C), exhaust valve control 10 ms/hour of backwash flow velocity, the backwash time about 30-45 minutes, generally use resin layer
Expansion rate controls backwash flow, notices that centre cannot have bulky grain resin to run out of, and at the end of backwash, slowly closing backwash is answered to intake
Whether valve (HV5917A/B/C), settles resin particle gradually, clear with positive and negative resin boundary surface after sedimentation, differentiates layering effect
Fruit repeats operation if once-through operation does not reach requirement to obtain satisfied layered effect；3) it regenerates: being first turned on lower valve
(HV5916A/B/C), column internal water accumulation is drained at the above 100-200 ㎜ of resin level, avoid it is unnecessary dilute again, then close
It closes lower valve (HV5916A/B/C), opens acid inlet valve (HV5921A/B/C), alkali-feeding valve (HV5920A/B/C), middle valve
HV5918A/B/C starts regeneration pump (P4508A/B), with identical regenerant flow simultaneously in lower part into acid, top into alkali, regenerates
Raffinate is discharged by middle comb, and 2-5 ms/hour of regeneration velocity, with 45 minutes by required soda acid even suction, and valve in controlling
(HV5918A/B/C) opening degree remains stationary liquid level in column；4) it cleans: after regenerated liquid sucks, closing injector into acid
HV5927A/B/C, alkali valve HV5930A/B/C enter mixed bed with pure water with 2-5 ms/hour of flow velocity simultaneously up and down, are arranged by middle row
Out, to wash away remaining regenerated liquid in pipeline and resin, and regenerated liquid is made to be reused, cleaning reaches defined acid to drain
Basicity is terminal, and general PH reaches 7-8；5) mix layer: after resin cleaning is qualified, valve (HV5915A/B/C) in opening is closed
Middle valve (HV5918A/B/C), alkali-feeding valve (HV5920A/B/C) are closed, is rinsed with back-washing method, loosens resin layer, then closed
It closes acid inlet valve (HV5919A/B/C), opens lower valve (HV5916A/B/C), column internal water accumulation is drained into the above 100- of resin level
At 150 ㎜, resin layer is made to have sufficient activity space, then opens intake valve (HV5921A/B/C) and mixed into compressed air
It closes, admission pressure 0.1-0.15Mpa, incorporation time is 3-5 minutes general, 2.5-3.0 ms/min of air inflow, abundant with resin in column
It is mixed into terminal, is then shut off intake valve (HV5921A/B/C), opens simultaneously inlet valve (HV5913A/B/ with most fast speed
C) and lower valve (HV5916A/B/C), valve (HV5915A/B/C) in closing, settles resin rapidly, prevents resin from settling
It separates again in the process, while to prevent resin from exposing the surface, aeration effluent quality otherwise can be generated between resin；6) just
It washes: closing lower valve (HV5916A/B/C), exhaust valve is closed when water is full of equipment, open lower valve (HV5916A/B/C),
It is positive with water flow processed and washes flow, into operating condition is just washed, just washed flow velocity and be generally 15-30 ms/hour, after water outlet is qualified, under closing
Valve (HV5916A/B/C) is opened outlet valve (HV5914A/B/C), is put into operation.
But in mixed bed pickling, alkaline cleaning procedure, comb primarily serves the effect of filtering resin, and middle comb in mixed bed
Interior strainer is often broken, so that resin will flow out together with acid-base waste fluid, is not easy to be found, is caused resin stream
It loses.
Therefore, the equipment that the loss of mixed bed regenerating resin can be reduced by how providing one kind is those skilled in the art's urgent need to resolve
The problem of.
Summary of the invention
In view of this, being able to observe that discharge the present invention provides the equipment that one kind can reduce the loss of mixed bed regenerating resin
Whether there is or not resin presence when acid-base waste fluid, and whether comb internal screen is broken in discovery in time, reduce because finding to generate not in time
Resin number of dropouts.
To achieve the goals above, the present invention adopts the following technical scheme:
