Description

A kind of flat bed as ion-exchange unit
Technical field
The utility model relates to a kind of flat beds as ion-exchange unit.
Background technique
Ion exchange technique is a kind of widely applied feed separation method, is referred in ion-exchange container, filling one The ion exchange resin for determining height, when water or solution flow through, the cation or anion and water or molten of inner resin of container absorption Cation or anion in liquid carry out ion exchange, are one to extract or go the process of certain ions in water removal or solution Kind belongs to the unit operation of mass transfer separation process.In demineralized water preparation, softening water process, wastewater treatment, hydrometallurgy, valuable gold Belonging to separation, organic matter purification, solvent recovery etc. has a large amount of application.
Ion exchange resin is a kind of insoluble high-molecular compound for having functional group, and structure is by high-molecular bone Frame, ion-exchange group and hole three parts are formed.Ion exchange resin can by by the ion exchange of exchange substance and Absorption reaches the separation of substance, displacement, purification, concentration, enrichment and other effects.The most important and valuable property of ion exchange resin, It is the invertibity of ion-exchange reactions, after application failure, usable acid, alkali or other regenerative agents are regenerated resin, restore it Exchange capacity enables ion exchange resin to use prolonged and repeatedly.
There are many type of ion-exchange container, and ion-exchange container is generally also called bed, common ion-exchange container There are fixed bed, moving bed, thermopnore etc..Ion-exchange container is generally vertical cylinder structure, and resin is deposited in container naturally, And there are certain spaces convenient for resin expansion cleaning.
Ion-exchange reactions is carried out on ion-exchange container.When water or solution pass through ion exchange layer, at one section Between after, resin is divided into three layers, and the resin of upper layer failure is " failure layer ", and it is " switching layer ", lower layer that middle layer, which is swapping, Not yet swap is " protective layer ".With the extension of exchanger runing time, the layer that fails is gradually increased, under working lining is continuous Drop, when working lining drops to the protective layer limit, starts the case where ion leakage occur, when working lining is entirely ineffective, from Son exchange need to be regenerated.
Theoretically, the effective dose of regenerative agent, total yield number should be with the operating capacity total yields of resin Number is equal.But in fact, having used high concentration regenerated liquid at double to make to regenerate faster more thorough.When regeneration level reaches It need to discharge it after it is required that, and be rushed the regenerative agent raffinate being adhered on resin again with irrigation (generally pure water or pure solvent) It washes off.Being multiplied for regenerant consumption and irrigation dosage is thus caused, usual regenerative agent capacity is 2 ~ 3 times of resinites Product, irrigation dosage are 2 ~ 3 times of resin volumes, thus in the operating cost of ion exchange system, regeneration expense accounts for main portion Point.In addition, the dosage of the regeneration level (regeneration rate) of exchanger resin and regenerative agent is not the relationship of being in line, when regeneration level reaches To after certain numerical value, even if being further added by regenerant consumption, regeneration level can not be significantly improved.Therefore, to make ion exchange skill Art is economically reasonable, generally regeneration level control below 60 ~ 80%.
And cause regenerative agent and irrigation dosage big, it regenerates one of halfway reason and is in conventional ion exchanging container There are excessive dead angle, regenerative agent and irrigation often efficiently can not quickly reach these dead zones, the tree of dead zone Rouge cannot carry out sufficiently effective contact with regenerative agent and irrigation, therefore the regeneration and flushing of this part resin consume largely Regenerative agent and irrigation, some parts can not even regenerate completely.On the other hand, when regenerative agent reaches dead zone and does not have When rinsing well, and the normal operation of equipment can be interfered with, so that operating index is not up to standard in a period of time after regeneration, caused Production run it is unstable.
Utility model content
Mentioned above in order to solve the problems, such as, the utility model provides a kind of flat bed as ion-exchange unit, By effectively reducing the dead zone inside bed body, the utilization rate of regenerative agent and irrigation is improved, regenerative agent and irrigation are reduced Dosage reduces the operating cost of ion exchange system;The utility model additionally provides a kind of ion exchange feed separation method.
A kind of flat bed as ion-exchange unit, the flat bed for handling water or solution, the flat bed by It successively include upper cover plate, circular cylinder body, lower cover plate under, the upper cover plate and lower cover plate are respectively provided with outlet/inlet, the circle Shape cylinder one end is connect with upper cover plate by flange bolt, and the circular cylinder body other end and lower cover plate are connected by flange bolt It connects, gasket is respectively provided between the circular cylinder body and upper cover plate, lower cover plate, between the upper cover plate and circular cylinder body, lower cover Water distribution grid, porous plate, filter cloth are set gradually between plate and circular cylinder body, are filled with amberlite in the circular cylinder body Rouge, the water or solution are entered by the outlet/inlet of upper cover plate, successively pass through water distribution grid, porous plate, filter cloth, ion exchange Resin.
Embodiment as one preferred, the water distribution grid include cloth water flow passage, and water distribution grid is in cover board and porous The cloth water flow passage of closed single flow direction is constituted between plate, the cloth water flow passage is helical form, the smooth no bending of cloth water flow passage.
Embodiment as one preferred, the cloth water flow passage is remoter apart from outlet/inlet, water distribution flow channel cross-section product It is smaller.

The utility model method additionally provides a kind of feed separation method of flat bed as ion-exchange unit, the object Expect separation method the following steps are included:
Water or solution are after pre-filtration system removes solid particle, organic matter, colloid, into the processing of first order flat bed After be discharged, if water outlet do not meet technical requirement, enter back into the second level flat bed processing after be discharged, such as water outlet also Technical requirement is not met, the processing of third level flat bed is entered back into, and so on, until water outlet meets the technical requirements, The first order flat bed, second level flat bed, third level flat bed are the flat bed above-mentioned as ion-exchange unit, The pre-filtration system includes at least one or more of quartz filter, active carbon filter, accurate filter.
Cause regenerative agent and big one of the reason of irrigation dosage be to exist in conventional ion exchanging container it is excessive dead Angle, regenerative agent and irrigation often can not cause the resin of certain dead zones not efficiently quickly by these dead zones It can regenerate completely, and be easy to cause regenerative agent to remain in other dead zones, a large amount of irrigations is needed to be rinsed, therefore is dead The regeneration and flushing of angular region domain resin consume a large amount of regenerative agent and irrigation, some parts can not even regenerate completely.It is logical Often, generally will just wash by regeneration-backwash-equal multiple working procedures are rinsed in the regeneration of conventional ion exchanging container, and regenerative operation is numerous Trivial complexity.
Traditional ion-exchange unit bed height and bed body diameter are stacked naturally than being generally 3:2 ~ 5:1, internal resin At leptosomatic resin column, the cycle of operation of equipment is often longer, and generally higher than 24 hours.When equipment is run, theoretically resin Should be able to be horizontal successively failure, switching layer successively move down from top to bottom, region before gradually becomes failure layer, the guarantor of lower section Sheath gradually becomes switching layer.But it is in actual operation, uneven due to flow rate of liquid, it is usually closer from material inlet Resin layer failure is faster, and remoter from material inlet resin layer failure is slower, some regions do not obtain ion exchange even and not Failure, resin layer are not successively to be failed with horizontal plane, but successively failed with male and fomale(M&F), and moving down with switching layer, Male and fomale(M&F) low dot location and the drop of high point position are increasing, cause the resin of same level there are a variety of working conditions, This has resulted in resin layer and has been easy to be pierced, and when resin regeneration has part resin to have not expired.In addition, since resin is nature heap It puts, the pressure of each point of resin column is uneven, be easy to cause the imperfect flow of liquid to generate channel, so that the region Resin ion exchange be not thorough, can not be worked normally.Due to the two, eventually cause the resin in some regions from Sub- exchange efficiency decline, or even do not exchanged;It is also the resin ion regeneration efficiency in this way, some regions when resin regeneration Decline, in addition do not regenerated or regenerative agent flushing be not thorough easy residual, these regions are called dead zone by we. In general, it is easiest to become dead angle area close to the region of bed wall part and the region of ditch stream part at the top and bottom of bed body Domain, these dead zones are not easy to regenerate or are not easy to rinse well regenerative agent.
The flat bed of the utility model method manufacture, avoids the dead zone of bed body cloth water-bound, when either running Or when regenerating, liquid can be allowed efficiently quickly through bed body, to ask so as to avoid the waste of the residual of regenerative agent and irrigation Topic.The flat bed of the utility model method manufacture, resin, which is compressed, in bed body is packed into flat structure, and uniformly fills up entire bed Internal portion, liquid are evenly distributed to entire resin layer plane by water distribution grid, since resin layer height is low, so resin is with water Plane successively fails from top surface to bottom surface, and the resin working condition of same level is consistent;It is uniform compaction additionally, due to resin , the pressure uniformity of each point not will form channel, and water or solution also just can not penetrate resin layer by channel shortcut; Flat structure and water distribution grid make the flow velocity uniformity of each point in the bed body including dead zone, and regenerative agent can be with It quickly reaches dead zone and dead zone will not be remained in when rinsing, dead zone can be with regular regeneration or flushing, thus originally The flat bed of utility model method manufacture has prevented the formation of dead zone, effectively reduces regenerant consumption and irrigation is used Amount, the ion-exchanging efficiency of resin are substantially improved, so that regeneration expense is greatly reduced.
