Effect is obvious, and essential equipment is belonged in current technique, and carclazyte bed is divided into hydrogenation carclazyte bed and the Regeneration Bleaching Clay bed,
Each serve as the effect for regenerating different degradation products.Such as oxidation reaction epoxy degradation product EPOXH4EAQ generated, pass through active oxygen
Regeneration H4EAQ can be easy to by changing aluminium (post-processing carclazyte bed), and activated alumina hydrogenates institute to EAQ and H4EAQ depth
The degradation product of generation has power of regeneration.In daily production, the activated alumina of post-processing carclazyte bed should be replaced in time, is prevented
After power of regeneration reduces, reproduction speed is lower than degradation speed, and system balancing is broken, and anthraquinone concentration is caused to decline, and then influences
Production.In existing post-processing carclazyte bed, after a period of use, steam regeneration must be carried out, so as to be adsorbed on carclazyte surface
Working solution detach, water must be filled carclazyte bed in original technique and put again by regeneration ending, Yao Jinhang cooling water temperature
Fall, so circulation three or four times, temperature could be dropped to resonable degree, otherwise can not be safely changed.
It is higher and higher to the discharge of wastewater requirement of company as environmental protection pressure is increasing, and the cooling down of the part
Water CODcr content is very high, average between 2000 ~ 20000, and with the continuous expansion of unit scale, wastewater flow rate is also more next
Bigger (for a set of 100,000 tons of devices, nearly disposable waste water of 300 tons of high concentration will be generated by often changing primary post-processing carclazyte bed),
Very big burden is brought to sewage treatment.And using circulating nitrogen gas cooling, then electric cost will rise, and mainly post-process white
Native bed does not have the dangerous substances such as hydrogen when usually running.Therefore, it is dropped if substituting disposable cooling water using other technique
Temperature, discharge amount not only safe but also that waste water can be greatly reduced, it will largely mitigate current environmental protection pressure.

The utility model proposes it is a kind of to after regeneration post-processing carclazyte bed use interior circulation temperature lowering technique device, have
Beneficial effect is: the device uses interior circulating cooling falling temperature method, can reduce by 2/3 wastewater discharge every time, mitigates environmental burden,
Meet the requirement of device clean manufacturing.
Detailed description of the invention
Fig. 1 be the utility model proposes it is a kind of to after regeneration post-processing carclazyte bed use interior circulation temperature lowering technique dress
The structural schematic diagram set.
In figure: bottom drain valve 1, post-processing 2, water valves 3 of carclazyte bed, compressed air valve 4, thermometer 5, inlet valve 6,
Outlet valve 7, water recirculator 8, inlet valve 9, communicating valve 10, water circulating pump 11, pressure gauge 12, outlet valve 13.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1, the post-processing carclazyte bed after a kind of pair of regeneration uses the device of interior circulation temperature lowering technique, including passes through pipe
The sequentially connected post-processing carclazyte bed 2 in road and water recirculator 8 post-process and are equipped with a water valve 3 and compression at the top of carclazyte bed 2
Air valve 4, post-processing 2 bottom of carclazyte bed are divided into two-way pipeline, wherein pipeline connection bottom drains valve 1 all the way, bottom drains valve 1
For sewage effluent, another pipeline by inlet valve 6 connect water recirculator 8, pipeline inlet valve 6 to post-processing carclazyte
Thermometer 5 is equipped between bed 2, for thermometer to detect the degree of cooling, 8 other end of water recirculator passes through piping connection circulation
Water pump 11, the piping connection between water circulating pump 11 and water recirculator 8 have communicating valve 10, and water circulating pump 11 is connected by pipeline
Post-processing carclazyte bed 2 is connect, the piping connection post-processed between carclazyte bed 2 and water circulating pump 11 has outlet valve 13, in following for pipeline
Pressure gauge 12 is equipped between ring water pump 11 and outlet valve 13, to detect pressure index, water recirculator 8 is equipped with pressure gauge 12
Outlet valve 7 and inlet valve 9, waste water by inlet valve 6 enter water recirculator 8 in, be discharged by communicating valve 10, cooling water by into
9 low level of water valve enters water recirculator 8, high-order to send out from outlet valve 7, and cooling water exchanges heat to hot waste water, and waste water is cold
But enter water circulating pump 11 afterwards, 2 top of post-processing carclazyte bed is returned to by outlet valve 13.
Using steps are as follows: after post-processing carclazyte bed steam regeneration, closing drains valve 1, opens a water valve 3,
Add disposable cooling water in post-processing carclazyte bed 2, after filling it up with, closes a water valve 3, open the import of water recirculator 8
