Description
Technical field
This application involves resin regeneration technical fields, more particularly to a kind of resin regenerating device.
Background technique
Engineering ADSORPTION IN A FIXED BED resin desorption mostly uses fair current to be desorbed, not only time-consuming, more consumption desorbing agent dosage, and need to match
Standby desorbing agent configuration storage tank, air compression system etc., with high costs, Chinese patent, publication number CN104291474A, publication date
On 01 21st, 2015, a kind of processing method of coking wastewater is disclosed, feature includes using resin tower, and work is desorbed in it
Skill is that traditional fair current is desorbed, and it is poor that there are desorption effects, and desorption time is long, the big disadvantage of desorbing agent dosage.
Publication date on 04 08th, 2008, it is raw to disclose a kind of wastewater from chemical industry by Chinese patent, publication number CN101254992A
Change the method for Tailwater Depth processing, the resin after adsorption saturation is that 3%~8% sodium hydroxide is molten with weight percent concentration
Liquid, water, 3%~8% hydrochloric acid, water are successively desorbed, and 10~60 DEG C of desorption temperature, separating process only rests on laboratory, not
Desorbing agent dosage can be effectively reduced and reduce desorption time, and do not consider the problems of that engineering exists, can not also provide engineering
Device.
Currently, counter-current regeneration technique has become the prevailing technology of ion exchange regenerant, but in absorption resin regeneration engineering
It is had not been reported in field.
In ion exchange counter-current regeneration, it is the key that guarantee counter-current regeneration effect that random layer, which does not occur, for ion exchange resin,
Therefore, the construction of ion exchange counter-current regeneration device is all much to surround how to prevent this premise of ion exchange resin unrest layer
's.Document (Ye little Fang design Suggestions on Internals of Ion Exchanger [J] electric power station system engineering, 2006,22 (05): 63-64.)
The middle design for illustrating intermediate drain installation is a key technology for counter-current regeneration equipment, and often occurs intermediate drain installation change in operation
Phenomena such as shape, fracture, the major measure solved are to increase reinforcing rib to reinforce intensity.Document (Chen Siyu cation and anion exchange
Device intermediate drain installation improves [J] equipment management and repairs, 2011, (S1): about 1-3 lunar periodicity of intermediate drain installation is illustrated in 145.)
The problems such as bending, deforming, not only causes resin to be lost, and soda acid consumption increases, and frequently replaces large labor intensity, time
It is long, with high costs, it can not solve the problems, such as at all, seriously affect the normal operation of device, recommendation on improvement is to increase welding steel
Plate reinforces intensity.
Publication date: Chinese patent, publication number CN 204973936U on 01 20th, 2016, are disclosed a kind of inverse without pressing
Flow regenerant ions exchanger, it is characterised in that: outlet pipe, outlet pipe including water feed apparatus and bottom at the top of cylinder, cylinder
On be connected with regenerated liquid import, be equipped with regenerated liquid discharger in the middle part of cylinder, the top junction of water inlet pipe and cylinder, which is equipped with, sets
Point water plate in cylinder, point water plate are curved plate-like structure, and the junction of outlet pipe and cylinder body bottom, which is equipped with, to be located in cylinder
The arc-shaped watertight shutter in portion, cylinder top also have exhaust tube, and the top of regenerated liquid discharger is made to form a low-voltage space.But it should
Device needs the intermediate drain installation using larger area, higher cost；Once and the flow velocity of regenerated liquid rises or intermediate drain installation occurs
Blocking, then easily lead to resin laminarization unrest layer, and low-voltage space is ineffective, which is applied to absorption resin occasion lower
Resin laminarization unrest layer is just easily led under regeneration velocity, resin desorption efficiency substantially reduces.Therefore the device can only be confined to from
Sub- exchange field, and can not apply in absorption resin art.
Therefore, the general character of ion exchange counter-current regeneration device is anion bed at present, is equipped on the resin layer
Packed resin layer (inert plastic ball, about 200mm are thick) or low-voltage space, and it is equipped with intermediate drain installation, it is generally located in packed resin layer and resin layer
Between.
The structure of intermediate drain installation in the prior art has following defects that
1, intermediate drain installation mostly use cross tee, fish-bone row etc. branch main pipe pattern, and tower body it is intracavitary use flanged joint, this
Kind of structure can not directly dismount outside tower body, clean or replace that difficulty is big, intensity is high, and the time is long, seriously affects the normal of device
Operation.
2, the installation site of intermediate drain installation is unable to satisfy resin bed volume contraction caused by efficiency lost resin, may cause pressure
Rouge layer can not play the role of pressing rouge, influence desorption effect.
3, such structure is to guarantee anion bed, needs the intermediate drain installation using larger area, is flowed through with meeting
The relatively low flow velocity that intermediate drain installation requires, higher cost；And still there are certain spaces to meet backwash to tower top for packed resin layer
It is required that once the flow velocity of regenerated liquid rises or intermediate drain installation blocks, then resin laminarization unrest layer is easily led to, packed resin layer loses
Effect, resin desorption efficiency substantially reduce.
4, such structure resin bed when handling high rigidity waste water under non-softening ion exchange or the organic object field of absorption are closed
Easy to harden, device is unable to operate normally.
5, such structure can not be applied in absorption resin art, because ion exchange is usually applied to water supply or advanced treating neck
Domain, waste water is cleaner, and density is smaller, and adsorbs resin art (removal organic matter) processing waste component complexity, and salt content is high,
Density is larger, and such structure is applied to absorption resin occasion and just easily leads to resin laminarization unrest layer under lower regeneration velocity,
Packed resin layer is ineffective, and resin desorption efficiency substantially reduces.
