The invention discloses a top-pressure-free countercurrent regeneration cation exchanger, which comprises a housing (1), a water inlet device (2) on the top of the housing (1), and a water outlet pipe (3) on the bottom of the housing (1), wherein cavity inside the housing (1) is provided with an intermediate drain device (4), and the upper side and the lower side of the intermediate drain device (4) are respectively provided with a resin pressing layer (5) and a resin exchange layer (6). The top-pressure-free countercurrent regeneration cation exchanger is characterized in that the water outlet pipe (3) is provided with a regeneration liquid inlet (7), and the intermediate drain device (4) is provided with an intermediate liquid discharge port (8). With the present invention, H<+> on an ion exchange resin is regenerated through inputting a regeneration liquid from bottom to top, and the regeneration liquid adopts the pipeline of the water outlet pipe, such that characteristics of simple structure and convenient use are provided, and the top-pressure-free countercurrent regeneration cation exchanger is suitable for promotion use.

Description

No roof pressure counter-current regeneration cation exchanger
Technical field
The present invention relates to ion-exchanger, specifically a kind of regenerated liquid of importing from bottom to up is to the H on the ion exchange resin +The no roof pressure counter-current regeneration cation exchanger of regenerating.
Background technology
Cation exchanger is a kind of when former water enters the cation exchanger of the strong-acid cation-exchange resin that the H type is housed, the H in the water on contained various cations and the ion exchange resin +Displacement reaction takes place, and the result of reaction is the various cation (Na in the water +, K +Deng) be attracted on the ion exchange resin H on the ion exchange resin +Then arrived in the water, the cation in the water almost only contains H +, various anion are had an effect and are generated various acids in it and the water.When effluent quality defective or produced the desalted water of certain volume after, it is out of service that ion-exchanger needs, to the H on the ion exchange resin +Regenerate, the general employing of existing regenerating unit imported regenerated liquid to the H on the ion exchange resin from top to bottom from the top of ion-exchanger +Regenerate, regeneration effect is bad.
Summary of the invention
The objective of the invention is problem, provide a kind of regenerated liquid of importing from bottom to up the H on the ion exchange resin at the prior art existence +The no roof pressure counter-current regeneration cation exchanger of regenerating.
The objective of the invention is to solve by the following technical programs:
A kind of no roof pressure counter-current regeneration cation exchanger, comprise the water feed apparatus of housing, case top and the outlet pipe of housing bottom, be provided with intermediate drain installation in the cavity of housing, the upside of intermediate drain installation and downside are respectively equipped with packed resin layer and exchange resin layer, it is characterized in that described outlet pipe is provided with the regenerated liquid import, leakage fluid dram in the middle of intermediate drain installation is provided with.
Described regenerated liquid import is positioned at the downside of the delivery port on the outlet pipe.
Described exchange resin layer downside is provided with the quartz sand thickness that is positioned at the housing intracavity bottom.
The quartz sand particle size of described quartz sand thickness is according to descending setting from top to bottom.
The present invention has following advantage compared to existing technology:
The present invention is by importing regenerated liquid from bottom to up to the H on the ion exchange resin +Regenerate, regenerated liquid is used the pipeline of outlet pipe, has characteristics simple in structure, easy to use, suitable promoting the use of.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Wherein: 1-housing; 2-water feed apparatus; 3-outlet pipe; 4-intermediate drain installation; 5-packed resin layer; 6-exchange resin layer; The import of 7-regenerated liquid; 8-middle leakage fluid dram; 9-delivery port; 10-quartz sand thickness.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1: a kind of no roof pressure counter-current regeneration cation exchanger, comprise housing 1, the outlet pipe 3 of the water feed apparatus 2 at housing 1 top and housing 1 bottom, be provided with intermediate drain installation 4 in the cavity of housing 1, the upside of intermediate drain installation 4 and downside are respectively equipped with packed resin layer 5 and exchange resin layer 6, exchange resin layer 6 downsides are provided with the quartz sand thickness 10 that is positioned at housing 1 intracavity bottom, the quartz sand particle size of quartz sand thickness 10 is according to descending setting from top to bottom, in the regenerated liquid import 7 that is provided with delivery port 9 downsides that are positioned on the outlet pipe 3 on the outlet pipe 3, leakage fluid dram 8 in the middle of intermediate drain installation 4 is provided with.
After ion-exchanger of the present invention uses a period of time, occur effluent quality defective or produced the desalted water of certain volume after, ion-exchanger needs out of service, regenerate, the step of regeneration is as follows: (1) small reverse washing: reply packed resin layer 5 carries out small reverse washing before the regeneration, accumulate in the dirt on packed resin layer 5 and the intermediate drain installation 4 during the flush away operation, during small reverse washing, intake from middle leakage fluid dram 8 input small reverse washings after closing water intaking valve and outlet valve, flow velocity is generally 5-10 rice/time, 3~5 minutes time.(2) input regenerated liquid: open the regenerated liquid valve at regenerated liquid import 7 places, regenerated liquid in outlet pipe 3 input ion-exchangers, is opened the middle tapping valve at middle leakage fluid dram 8 places again, regeneration liquid waste is discharged by middle leakage fluid dram 8.Be to guarantee regeneration effect, regeneration velocity should be controlled at 5 meters/time, the regeneration acid strength is controlled at 1.5-3%.(3) for a short time just wash: in advancing the regenerated liquid process, have the part acid solution and infiltrate in the packed resin layer 5, just wash water consumption and shorten and just wash the time, before just washing, wash this part waste liquid even with little just washing in order to save; Little when just washing, open water intaking valve open then in the middle of middle the tapping valve at leakage fluid dram 8 places, water is from middle leakage fluid dram 8 discharges, flow velocity is controlled at 10-15 rice/time, about time 5-10 minute.Little just washing end after, tapping valve in the middle of closing is opened and just to be washed draining valve and just wash, flow velocity is treated to close draining valve when effluent quality meets the requirements with the operation flow velocity, opens the outlet valve normal operation input.
The present invention is by importing regenerated liquid from bottom to up to the H on the ion exchange resin +Regenerate, regenerated liquid is used the pipeline of outlet pipe 3, has characteristics simple in structure, easy to use, suitable promoting the use of.
Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of being done on the technical scheme basis all falls within the protection domain of the present invention; The technology that the present invention does not relate to all can be realized by prior art.
