Put.
Background technology
The large-scale water treatment system such as thermal power plant, chemical industry, petroleum industry needs substantial amounts of demineralized water, frequently with ion in industry
The method of exchange.Ion-exchange demineralization principle is by the salt in cloudy (sun) resin substitution water, reaches water outlet and accordingly
Ask.Ion exchange principle：(H-R)+(M+)-->：(M-R)+(H+)
Reliving is needed after the displacement completely of the functional group of resin, needs to carry out backwash to resin before Reliving.Backwash
There are two purposes, it is specific as follows：
Purpose one：The pollutant that resin surface retains is gone out, if the pollution cooperating microorganisms of retention meeting for a long time, degraded tree
Fat, influences resin service life.
Purpose two：Resin fully expands, if backwash is insufficient, particularly now before universal ion interchange unit equipped with anti-
Permeability apparatus pro desalting, water inlet salt content reduce, but the ion-exchanger cycle of operation extends, and long period operation may cause
Resin lumps, and backwash expansion is incomplete, can influence effluent quality and exchanger water production in periodic mode.
The backwash control for ion-exchanger has two ways at present, specific as follows：
Mode one：Backwash flow of inlet water is once mixed up, later stage operation installation procedure sets operation, its advantage is：Nobody
It is on duty, reduce operation workload；The drawback is that：Backwash situation cannot be monitored, cannot be made adjustment in time, resin may be caused to rush
Go out exchanger or expansion is incomplete.
Mode two：Manual backwash, spies on resin by eyes observation, manually adjusts backwash flow, its advantage is：Can root
According to backwash concrete condition, backwash flow is adjusted, reaches the adequately expanded purpose of resin；The drawback is that：It can not achieve fully automated
Change control, be about 20~30min/ time per the time of backwash, especially for big yield system, more ion exchanges while again
More people's coordinated manipulations are needed to configure when raw, increases operating cost, can not realize unattended.
The content of the invention
The technical problems to be solved in the utility model is：In order to overcome the deficiencies in the prior art, there is provided Yi Zhongli
Sub- exchanger backwash self-checking device, backwash water inlet use pneumatic flowrate regulating valve combination optoelectronic switch, reach backwash and adjust automatically
The purpose of section.
Technical solution is used by the utility model solves its technical problem：Ion-exchanger backwash automatic adjustment dress
Put, there is the closed tank body for being pre-charged with resin, backwash inlet channel has been penetrated on the can body of the closed tank body, it is described
There is backwash water inlet pneumatic flowrate regulating valve, the backwash water inlet is connected to backwash with pneumatic flowrate regulating valve and intakes on can body
On pipeline；The top perforate of can body is equipped with the low level optoelectronic switch for being used for controlling backwash water inlet pneumatic flowrate control valve opening,
The upper end cover perforate of closed tank body is equipped with the high-order optoelectronic switch for being used for controlling backwash water inlet pneumatic flowrate control valve opening.
The beneficial effects of the utility model are：Ion-exchanger backwash self-checking device provided by the utility model, leads to
Cross and the control valve of backwash water inlet is designed to pneumatic flowrate regulating valve, it is possible to achieve flow adjust automatically, and pass through height
Optoelectronic switch catches the reflection wavelength difference of resin and water to judge resin height, and simple and convenient, pneumatic flowrate regulating valve combines
Optoelectronic switch, adjust automatically backwash water, realizes the Automatic Control of ion-exchanger backwash, enables ion exchange system true
Just realizing unattended.
