Abstract
The utility model relates to a counterflow ion exchanger which is provided with a tank, water distribution devices are arranged at the bottom and on the top of the tank, an icon exchange chamber is arranged in the middle of the tank, which is filled with icon exchange resin layer and a volume compensation layer is filled between the icon exchange resin layer and the water distribution device a the top. The volume compensation layer can be composed by inert resin and a plurality of volume compensation air bags. The volume compensation layer is used to substitute for the expansion space of resin. During the regeneration of a resin bed layer, the volume of resin increases but a volume compensation air bag is compressed and the volume gets smaller, which is offset by the increased volume due to the expansion of the resin bed layer and thus keeping the resin bed layer not moved upon the function of the pressure from the volume compensation layer but without producing over internal stress due to the expansion of the resin bed layer. When running, the resin bed layer breaks down continuously, the volume gets smaller while the volume compensation layer expands correspondingly, truly realizing counterflow regeneration Amberpack fixed bed which is simple in structure and short in regeneration time, saves regenerating fluid and has good quality of water.
Description
Technical field
The utility model relates to a kind of water treatment facilities, particularly a kind of full chamber fixed bed countercurrent regenerating ion exchanger.
Background technology
At present, in water treatment field, the ion-exchanger great majority that use are that floating bed, co-current regeneration fixed bed, water or pneumatic jack are pressed countercurrent regenerating fixed bed etc., its weak point is: floating bed suspends in running and will lose efficacy the system water that just can resume operation of must regenerating again because of the random layer of denidation; Water or pneumatic jack are pressed the countercurrent regenerating fixed bed complicated operation, often cause regeneration effect bad because operation control is improper, influence system water water quality and operation system water cycle; When co-current regeneration fixed bed regeneration and develop fee, waste regenerative agent and water.In addition in the process of ion-exchanger operation and regeneration, the volume of ion exchange resin will dwindle or expand, so general ion-exchanger is when loaded resin, all must leave the expansion that certain expansion space compensates the resin volume, otherwise not stay the expansion space will cause ion-exchanger structural deterioration and the fragmentation of ion-exchange resin particles pressurized.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of full chamber fixed bed countercurrent regenerating ion exchanger, and it is simple in structure, and the recovery time is short, saves regenerated liquid, and effluent quality is good.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of countercurrent regenerating ion exchanger, be provided with tank body, the bottom and the top of tank body are provided with water dispensing apparatus, the middle part of tank body is an ion-exchange chamber, be characterized in: the indoor resinbed that is filled with of ion-exchange is filled with by the volume compensation layer between resinbed and top water dispensing apparatus.
The technical problems to be solved in the utility model can also come by the following technical programs to realize that further described volume compensation layer is made up of inert plastic and some volume compensation air bags that the volume compensation air bag is evenly arranged in the inert plastic.
The utility model is the expansion space that replaces resin with the volume compensation layer.When resin regeneration, because the effect that regenerated liquid upwards flows makes resin bed produce the trend that moves up, resin bed is just as one " piston ", to the volume compensation layer generation pressure on top.The active force of volume compensation layer downward back-pressure resin bed because of pressurized produces, and stop resin bed to move up.Like this, resin bed just can not move up and float in regenerative process, and whole resin bed maintains static.In regenerative process, the resin volume increases, and causes resin bed to expand, and the resin bed height increases, and resin bed compression volume layer of compensation makes the volume compensation layer dwindle because of pressed volume.The volume that volume that the volume compensation capsule dwindles and resin bed expansion increase is cancelled out each other.Volume compensation effect by means of the volume compensation layer, just make resin bed in regenerative process, be subjected to always the volume layer of compensation pressure effect and maintain static, simultaneously, be unlikely to again to produce excessive internal stress, cause the ion-exchanger structure to be damaged and the fragmentation of resin particle pressurized because of the expansion of resin bed.During operation system water, along with the inefficacy of ion exchange resin, the resin bed height reduces, and volume compensation layer volume also expands thereupon.Entirely ineffective when resin bed, when ion-exchanger stopped into water, the volume compensation layer expand near original volume thereupon.The design makes ion-exchanger realize the full chamber of counter-current regeneration fixed bed veritably, and in operation and regenerative process, ion-exchanger tank body and ion-exchange resin particles can not be subjected to excessive internal stress.It is simple in structure, and the recovery time is short, saves regenerated liquid, and effluent quality is good.
