Abstract
The invention discloses a device for fixed bed ion exchanger regenerative bed crack, used for chemical production and industrial water disposal. A distributor capable of integrally moving up and down by drive of a rotary device mounted on the external of the fixed bed ion exchanger is installed under an ion exchange resin support plate in a traditional fixed bed ion exchanger, the distributor is composed of a horizontal pipe and more than one vertical pipes connected above the horizontal pipe. The invention reversely blows beds in areas when an ion exchange resin regenerative bed cracks, can lead ion exchange resin to fully suspend and be totally loose, which is favorable for subsequent total regeneration. The beds crack quickly with good effect, and simultaneously discharge capacity of reverse blow media is reduced, thereby avoiding impact to fresh water or other reverse blow media.
Description
Technical field
The present invention relates to a kind of Chemical Manufacture and Treatment of Industrial Water equipment, be specifically related to the fixed bed ion exchange equipment in Chemical Manufacture and the Treatment of Industrial Water.
Background technology
In the traditional technology, when carrying out the bed fracture in the fixed-bed ion exchanger regenerative process, former process liquor and the countercurrent flow in interchanger of blowback medium, the direction of former process liquor from top to bottom, the blowback medium from bottom to top flows, and ion exchange resin is fully suspended, make the fixed bed bed loose fully, prevent local caking, realize the bed fracture, make ion exchange resin be able to thorough regeneration.But in this traditional bed fracture operation process, the blowback medium upwards flows through whole bed, in case pine is blown in a certain part of bed, after ion exchange resin suspends, should the loosening fluid flow resistance of locating descend, the blowback medium will be concentrated from this and pass through, and other position of ion exchange resin can not be blown, can not improve action effect even prolong action time yet, cause the weak effect of fixed-bed ion exchanger bed fracture, local caking, ion exchange resin is difficult to thorough regeneration, influences its life cycle.This traditional bed fracture mode needs the instantaneous delivery of blowback medium very big simultaneously, and the blowback medium system is had very big impact, causes fluctuation.
Summary of the invention
In order to overcome the deficiencies in the prior art, purpose of the present invention provides a kind of device that is used for fixing the fracture of bed ion exchanger regenerator bed, with in the blowback media set to the bed ion zoning of bed territory blowback carry out bed fracture, advance gradually, make ion exchange resin be able to thorough regeneration, reduce the flow of blowback medium, avoid impact the blowback medium system.
The present invention is achieved through the following technical solutions: a kind of device that is used for fixing the fracture of bed ion exchanger regenerator bed, comprise: the interface that is arranged on the former process liquor of input at ion-exchanger top or discharge blowback medium is arranged on the blowback medium inlet and the outlet of former process liquor of ion-exchanger bottom, be filled in the ion exchange resin in the ion-exchanger, it is characterized in that in fixed-bed ion exchanger, install under the ion exchange resin back up pad by wheelwork and drive the sparger that can whole move up and down, and sparger integral body can be rotated under the drive of wheelwork, the vertical tube that described sparger is slightly less than the level pipe of ion-exchanger internal diameter by a length and is connected this level pipe top constitutes, described sparger level pipe is connected with the blowback medium inlet, and described vertical tube quantity is more than one.
The invention has the beneficial effects as follows: the present invention concentrates and uses the blowback medium the subregion blowback of ion exchange resin bed layer, advances gradually, ion exchange resin fully can be suspended, and is loose fully, thoroughly regeneration.Sparger can integral body move up and down, and sparger moved on the whole when the bed breaking-down process began, and to the blowback of zoning of bed territory, sparger integral body moved down after bed thoroughly ruptured, and did not influence the carrying out of other process.Therefore bed crack velocity of the present invention is fast, effective, can reduce the flow of blowback medium simultaneously and then avoid impact to process water or other blowback medium system.

Embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
A kind of device that is used for fixing the fracture of bed ion exchanger regenerator bed, comprise: be arranged on the input process liquor at ion-exchanger 11 tops or the interface 1 of discharge blowback medium, be arranged on the blowback medium inlet 8 and the former process liquor outlet 9 of ion-exchanger bottom, be filled in the ion exchange resin 2 in the ion-exchanger, be installed in the fixed-bed ion exchanger 11, the sparger 5 that the ion exchange resin back up pad can whole be moved up and down by wheelwork 6 drives for 10 times, the vertical tube that this sparger is slightly less than the level pipe of ion-exchanger internal diameter by a length and is connected this level pipe top constitutes, and described vertical tube quantity is more than one.Filter cap 4 is installed on the ion exchange resin back up pad 10, prevents the loss of ion exchange resin.The visor 3 that is installed in the ion-exchanger sidewall is used to observe the blowback effect of resin in the ion-exchanger.During the fracture of ion exchange resin regeneration bed, be full of the blowback medium in the fixed-bed ion exchanger, sparger integral body moves up, the blowback medium is upwards penetrated by the vertical tube mouth of pipe on the sparger, because the vertical tube mouth of pipe on the sparger is pressed close to the ion exchange resin back up pad at this moment, so the blowback medium that penetrates can only concentrate the duct on the back up pad of vertical tube mouth of pipe top to enter fixed bed basically, blows this regional ion exchange resin, makes it suspend rapidly, seethe.Sparger 5 integral body are slowly rotation under the drive of wheelwork 6, the bed ion bed thoroughly can be blown pine, fracture after rotating several weeks (as long as in fact Rotate 180 °).Then sparger 5 integral body are moved down, carry out other step of regenerative process.Wheelwork 6 places the fixed-bed ion exchanger outside, is driven by motor 7.
In the caprolactam production process, caprolactam water solution need carry out ion-exchange to remove inorganic impurity in fixed-bed ion exchanger, use the process water blowback when bed ruptures in the regenerative process, flow is 90m3/h, rupture time is 0.5h, and the life cycle of regeneration back ion-exchanger is 3 days.Under the constant situation of other condition, use the present invention to be used for fixing the device of bed ion exchanger regenerator bed fracture, sparger level pipe diameter is 100mm, length is 1500mm, and the vertical tube diameter is 25mm, totally 18, using process water blowback, flow during the bed fracture is 30m
3/ h, rupture time are 0.05h, and bed fracture device rotated for two weeks, and the life cycle of regeneration back ion-exchanger is 6 days.From visor observation also can know see use the present invention after bed fracture effect obviously improve.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
