Ion-exchange demineralization experiment is one of the experiment that must be opened in the teaching of environmental engineering speciality water treatment experiment, passes through experiment
Reach and consolidates basic principle, verifying basic law, the purpose for being familiar with treatment process.Although large and medium-sized ion exchange experiments device
Close to water treatment facilities in process flow, be conducive to be familiar with process control, but device pipeline is complicated, fails between technological parameter
Accurate matching, operating parameter is difficult to be precisely controlled, and number of devices is limited, and student completes the content of courses within the defined time limit to be had
It is difficult.
Summary of the invention
The utility model provides a kind of small ion exchange desalination experimental provision, for basic in ion-exchange demineralization experiment
The verifying of principle and basic law part.
The technical solution of the utility model are as follows:
A kind of small ion exchanges desalination experimental provision, by raw water slot (1), peristaltic pump (2), cation exchange column (3,4),
Triple valve (5,8,10), anion-exchange column (6,7), mixed column (9), pure water slot (11), sample tap (12,13,14) composition.
Raw water slot (1) is equipped with water sample to be processed, is connected with peristaltic pump between raw water slot (1) and cation exchange column (3)
(2), by placed in series between cation exchange column (3,4), cation exchange column (4) and anion-exchange column (6) pass through three
Port valve (5) is connected to, and by placed in series between anion-exchange column (6,7), anion-exchange column (7) passes through with mixed column (9)
Triple valve (8) connection, mixed column (9) are connect through triple valve (10) with the pipeline in pure water slot (11).
The cation exchange column (3,4), anion-exchange column (6,7), mixed column (9) are all made of organic glass control
At organic glass pipe diameter is 60mm, and height and diameter ratio are between 6~10, and lower end sealing, upper end is equipped with rubber plug, rubber plug
It is upper to be furnished with water inlet pipe and outlet pipe, it is lower to the anti-water outlet fixed-bed ion exchanger of stream；Cation, anion-exchange column difference
Equipped with highly acid, strong basic ion exchange resin, in mixed column (9), highly acidic cation, strong-base anion-exchange resin
Volume ratio is 1:1.5.
The triple valve (5,8,10) is equipped with sample tap (12,13,14), is connect respectively using sample tap (12,13,14)
Take cation exchange column water outlet, anion-exchange column water outlet and mixed column water outlet.
The peristaltic pump (2) is preferably flow type peristaltic pump, conveying and flow control for water.
The ion exchange column of the utility model is made using lucite tube, handles work to the anti-water outlet fixed bed of stream using lower
Skill, process flow are simple, clear；The flow of water, operating status are accurately controlled using laboratory common apparatus flow type peristaltic pump
More stable, experimental data more tends to coincide with basic principle, basic law.The device is easy batch making, at low cost, land occupation
It is small, the verifying of basic principle and basic law is laid particular emphasis in the content of courses, and it is few to religion effectively to make up large and medium-sized number of devices
Influence.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In Fig. 1: 1 raw water slot；2 peristaltic pumps；3,4 cation exchange column；5,8,10 triple valve；6,7 anion exchange
Column；9 mixed columns；11 pure water slots；12,13,14 sample tap.
Specific embodiment
The utility model is elaborated with reference to the accompanying drawing.
As shown in Figure 1, a kind of small ion exchange desalination experimental provision of the utility model is by raw water slot (1), peristaltic pump
(2), cation exchange column (3,4), triple valve (5,8), anion-exchange column (6,7), mixed column (9), pure water slot (10), sampling
Mouth (11,12) composition.
Water sample to be processed is promoted by peristaltic pump (2) in raw water slot (1), enters concatenated cation exchange column (3,4),
Water outlet is entered concatenated anion-exchange column (6,7) by triple valve (5) again, and water outlet enters via triple valve (8) mixed again
Zygostyle (9), water outlet enter pure water slot (11) through triple valve (10).When device is stable, sun is taken by sample tap (12)
Ion exchange column water outlet, takes anion-exchange column to be discharged, takes mixed column to be discharged by sample tap (14) by sample tap (13), point
It carry out not pH, conductivity, Hardness Determination；Wriggling pump discharge is promoted, the flow velocity of water is increased, after device is stable, respectively
Water sample is taken in sample tap (12,13,14), pH, conductivity, total hardness is measured, compares different location, lower pH different in flow rate, electricity
The situation of change of conductance, total hardness index.
