The process system that pure water is quickly prepared using the shallow-layer bed ion-exchange unit of the utility model, prepares the work of pure water
Skill step includes：
The first step, pure water preparation process：The valve of raw water inlet pipeline is opened, opens intake pump, raw water sequentially enters shallow
Layer cation bed, shallow-layer anion bed, thereafter let out system, this step is to produce the process of pure water.The water of final discharge system is as pure
Water, depending on this step duration is with the water quality of raw water；
Second step, resin regeneration step 1：The valve of raw water inlet pipeline is closed, intake pump is closed, opens alkali storage tank dosing
Pump, valve, acid storage tank dosing pump, valve open regeneration liquid waste valve, acid solution are squeezed into shallow-layer cation bed, lye squeezes into shallow-layer anion bed,
The regeneration liquid waste discharge system generated in regenerative process, the time control of this step is within 60s；
Third walks, resin regeneration step 2：Acid storage tank, alkali storage tank dosing pump, respective valves are closed, are kept at regenerating valve
In open state, flushing water valve is opened, shallow-layer cation bed, shallow-layer anion bed are rinsed with flushing water, by most of medicine of internal residual
Agent is with flushing liquor discharge system, and the time control of this step is within 60s；
4th step, resin regeneration step 3：The valve of flushing water flushing line is closed, regeneration liquid waste pipe valve is closed, beats
The valve on open cycle radiator drain road opens intake pump, closes shallow-layer anion bed outlet pipeline valve, opens shallow-layer anion bed Hui Xun
Ring water tank pipe valve carries out internal circular treatment, until the water quality in cyclic water tank reaches pure water standard, control as this step 1
System is within 90s；
5th step, pure water preparation：The step of repeating the first step
The principle that the present invention prepares pure water is：Cation in raw water is when by shallow-layer cation bed, by positive resin particle
Cation exchange groups adsorb and carry out ion exchange, release hydrogen ion.Containing hydrogen ion shallow-layer is subsequently entered with the water of anion
Anion bed, the anion in water adsorb and carry out ion exchange when by shallow-layer anion bed by the cation exchange groups on negative resin particle,
Release hydroxide ion.Hydrogen ion is combined into water with hydroxide ion, and since electroneutral is presented in raw water, zwitterion charge is protected
Conservation is held, by shallow-layer bed treated water, no longer contains any ion, this part water can be used directly as pure water.
Half section after regeneration of ion-exchange process, remaining a certain amount of acid treatment in cation bed are remaining a certain amount of in anion bed
Alkali medicament, the removal relative difficulty of this part medicament, because its concentration is very low, still, the presence of this part low concentration medicament,
Prodigious influence is caused on the production water of system.
Conventional ion switching equipment regenerates back segment in medicament, needs to be rinsed (the medicament of low concentration with a large amount of pure water
It is difficult to rinse thoroughly), and the producing water water quality of system in the early stage cannot generally reach pure water standard (the clean medicament of non-cleaning down
Caused interference), about 30 minutes or so time is needed to carry out working condition (producing water water quality time up to standard, preceding half an hour
The time producing water water quality of left and right cannot be up to standard).
It is equipped with cyclic water tank in this system, the pure water in cyclic water tank is extracted out with water pump, it is cloudy to squeeze into shallow-layer cation bed, shallow-layer
In bed, the water outlet of shallow-layer anion bed turns again in cyclic water tank, can be at 60~80 seconds or so under the high-efficient water flow effect of water pump
Time in, by sour solvent remaining in shallow-layer cation bed, all send to shallow-layer anion bed and adsorbed and neutralized, it is residual in shallow-layer anion bed
Remaining alkali soluble agent, all send to shallow-layer cation bed and is adsorbed and neutralized, and remaining soda acid medicament is by corresponding shallow-layer cation bed, shallow-layer
After anion bed is adsorbed and neutralized, the water that retains in entire shallow-layer bed system (resin equipment, cyclic water tank, pipeline) is pure
Water carries out pure water preparation processing at this point, can directly switch corresponding valve, and the pure water of generation can direct plunge into production and application, no
Unqualified production water of any initial stage is will produce, because remaining drug concentration is very low, this part operation is not substantially to the suction of resin bed
Attached capacity impacts, and does not influence the water yield of signal period.
The equipment of the utility model has small and beautiful advantage, is mainly shown as：Occupation area of equipment is small, automates journey
Degree is high, and core resin utilization rate is high, and follow-up maintenance is easy, miscellaneous investments cost it is more cheap (including early period one-time investment at
Originally, later stage wearing detail replaces maintenance cost).
