A kind of ion exchange column
Technical field
The utility model belongs to the chemical industry equipment field, especially a kind of ion exchange column.
Background technology
Ion exchange column be a certain proportion of cationic, anionic exchange resin mixed packing in same switch, the ion in the convection cell exchanges, removes.Because functions such as its unique purification, exchange obtain using comparatively widely at industrial departments such as light industry, medicine, chemical industry.From handing over post can be divided into fixed bed, three kinds of moving bed, continous way thermopnores continuously according to operation format, wherein fixed-bed type is from handing over post more commonly used.Fixed-bed type is a tank body from the main body of handing over post, and the ratio of height to diameter of its tank body is the key factor of influence exchange effect.Owing to be divided into three layers in the tank body, the top is used for being sprayed onto tank interior to material liquid uniformly for spraying the distributor of material liquid, and intermediate host partly is a resin bed, and composition a small amount of quartz sand in bottom is used to separate discharge liquid and resin after the exchange.In the part that internal liquid is discharged,, lump easily, thereby influence follow-up exchange effect owing to mix with pot liquid for a long time.
The utility model content
The technical problem that the utility model will solve provides and a kind ofly can promote it to separate to the resin of jar inner bottom part and liquid, avoids the ion exchange column that lumps.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of ion exchange column, comprise tank body, and charging aperture place, said tank body top is provided with distributor; The tank body bottom is provided with discharging opening, it is characterized in that the middle and lower part of said tank body is provided with air agitator.Air agitator in the utility model is connected with outside air pump, feeds gases at high pressure, blows material liquid that is positioned at tank base and resin, makes the tank interior liquid flow, prevents caking, influences liquid and carries and exchange effect.
Preferably, the structure that the crisscross pipeline of said air agitator is formed, said pipeline endcapped is interconnected between the pipeline, and the side of pipeline is opened and evenly is provided with fumarole.
Preferably, said air agitator is made up of a trunk line and the arm more than that is connected with trunk line, and said arm is symmetrical in trunk line and distributes.Air agitator in the utility model is simple in structure, and is easy to installation and maintenance.
Adopt the beneficial effect that technique scheme produced to be: the utility model is on the basis of existing equipment; In the tank body middle and lower part, be positioned at the bottom of resin bed, increased air agitator; Blow the liquid of resin bed bottom through air; It is flowed, can prevent that resin and liquid from producing caking phenomenon, thereby influence the conveying of liquid and the exchange effect of resin and liquid intermediate ion; Air agitator in the utility model is the pipeline of closed-end, offers fumarole on the sidewall of pipeline, and it is simple in structure, and I&M is convenient, and effect is obvious.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of air agitator;
Wherein, 1, distributor, 2, tank body, 3, air agitator, 3-1, trunk line, 3-2, arm, 4, discharging opening.
The specific embodiment
Can know that according to accompanying drawing 1 the utility model is specifically related to a kind of ion exchange column, comprise tank body 2, charging aperture place, tank body 2 top is provided with distributor 1, and tank body 2 bottoms are provided with discharging opening 4, and the middle and lower part of tank body 2 is provided with air agitator 3.
Drawings attached 2 can know, air agitator 3 is made up of a trunk line 3-1 and the arm 3-2 more than that is connected with trunk line 3-1, and arm 3-2 is symmetrical in trunk line 3-1 and distributes, and wherein evenly offers fumarole on the sidewall of trunk line 3-1 and arm 3-2.Arm 3-2 on the air agitator 3 is positioned on the same horizontal plane, and the peripheral profile of arm 3-2 is a sub-circular, matches with the inner chamber of tank body 2.
The specific embodiment of the utility model: at first the bottom in tank body 2 inserts a small amount of quartz sand, makes it cover the bottom and gets final product, and charges into resin then; Tank body 2 is sealed, and then the upper end by distributor 1 feeds material liquid, makes it form the liquid that evenly sprays; Fall on the resin bed, material liquid is fully mixed with resin, start the external high pressure air pump simultaneously; Charge into pressure-air in the air agitator 3, make the liquid flow of resin bottom, this be lower floor liquid will with resin isolation; Through quartz sand, flow out from discharging opening 4, accomplish the ion exchange process of material liquid and resin.
