Abstract
The utility model provides a cleaning system of a prefilter in a melamine ultrafiltration system, relates to a cleaning device, and aims to provide a cleaning system of a prefilter in a melamine ultrafiltration system without manual core-pulling cleaning for overcoming the defects in the prior art. The utility model adopts the following technical scheme that the cleaning system of the prefilter in the melamine ultrafiltration system comprises an OAT serum tank, the OAT serum tank is connected with the prefilter in the melamine ultrafiltration system through an ultrafiltration feeding pump, and the prefilter in the melamine ultrafiltration system is connected with the ultrafiltration system; and the cleaning system further comprises a high pressure steam condensate flash tank which is connected with the prefilter in the melamine ultrafiltration system through a pipeline and used for conveying steam condensate or concentrated condensate to the prefilter in the melamine ultrafiltration system, and the piping of the prefilter in the melamine ultrafiltration system is used for being connected with a residence liquid groove for recovering the waste cleaning liquor. The utility model is mainly applied to clean the prefilter in the melamine ultrafiltration system.
Description
Technical field
The utility model relates to a kind of cleaning device, particularly relates to the purging system of ultrafiltration system prefilter in a kind of Melamine Production.
Background technology
In the high-pressure process triamine production process, because melamine hydrolysis, can generate hydrolysates such as melamine monamide, melamine diamides, be referred to as OAT, by the OAT crystal system its crystallization is separated out and form a kind of milky coating shape slurries, be collected in the OAT slurry tank, deliver to ultrafiltration system by OAT slush pump (ultrafiltration feed pump), utilize the ceramic capillary filtering technique to be separated into cleaner liquid (return before system make the technology circulation fluid) and stagnant liquid (send cracking system to be decomposed into ammonia and carbon dioxide reclaims) again.The OAT slurries send before the ultrafiltration system must by the ultrafiltration system prefilter filter out wherein impurity and the bulky grain thing with anti-clogging ultrafiltration ceramic capillary.The ultrafiltration system prefilter is two, and one opens one is equipped with, and switches the cleaning of manually loosing core when operation platform pressure reduction reaches 50KPa.The deficiency that prior art exists:
1. manually loosing core, it is big to clean labour intensity, and repeatedly the demolition, installation filter core very easily causes filter core to damage, be out of shape, and filter gland mat is changed frequent;
2. the OAT residue and the insoluble matter that produce in each artificial cleaning process can not be handled contaminated environment.
The utility model content
The purpose of this utility model is that provide for the shortcoming that overcomes prior art a kind of need not the melamine ultrafiltration system prefilter purging system of manually loosing core and cleaning fully.Reduce to pollute, and damage equipment not, the service life of improving equipment.
The purpose of this utility model realizes by following technical proposal: melamine ultrafiltration system prefilter purging system, comprise the OAT slurry tank, the OAT slurry tank is connected with the ultrafiltration system prefilter by the ultrafiltration feed pump, the ultrafiltration system prefilter is connected with ultrafiltration system, also comprise a high steam condensate flash groove, high steam condensate flash groove is connected with the ultrafiltration system prefilter by pipeline and is used for to ultrafiltration system prefilter delivering vapor condensate liquid or concentrated condensate liquid, ultrafiltration system prefilter pipe arrangement be used to reclaim the delay liquid bath that cleans waste liquid and be connected.
From architectural feature of the present utility model as can be seen, advantage of the present utility model is: the shortcoming that has overcome prior art, need not the cleaning of manually loosing core, so there is not regular dismounting filter core, improved the service life of equipment, the residue and the insoluble matter that produce after cleaning are in addition rationally discharged, and can not pollute environment after handling once more.
Description of drawings
The utility model will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present utility model
Wherein Reference numeral 1 is that OAT slurry tank 2 is ultrafiltration feed pumps
The 3rd, ultrafiltration system prefilter 4 is ultrafiltration systems
The 5th, high steam condensate flash groove 6 is to be detained liquid bath
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Preferred embodiment
Melamine ultrafiltration system prefilter purging system as shown in Figure 1, comprise OAT slurry tank 1, OAT slurry tank 1 is connected with ultrafiltration system prefilter 3 by ultrafiltration feed pump 2, ultrafiltration system prefilter 3 is connected with ultrafiltration system 4, also comprise a high steam condensate flash groove 5, high steam condensate flash groove 5 is connected with ultrafiltration system prefilter 3 by pipeline and is used for to ultrafiltration system prefilter 3 delivering vapor condensate liquids or concentrated condensate liquid, ultrafiltration system prefilter 3 pipe arrangements be used to reclaim the delay liquid bath 6 that cleans waste liquid and be connected.
The utility model has made full use of the characteristic that OAT easily is dissolved in weak aqua ammonia and hot water, gather materials on the spot, the configuration pipeline utilizes the steam condensate (0.6MPa of high steam condensate flash groove, 160 ℃) or concentrated condensate liquid (contain ammonia 3.5%, 0.4MPa, 50 ℃) as the cleaning water source of ultrafiltration system prefilter, to switching the filter element on-line cleaning that, the cleaning waste liquid is recycled to the delay liquid bath and send cracking system to reclaim again, the utility model is through after transforming, solved the problem that prior art exists, need not the cleaning of manually loosing core, saved cost and improved environment.
Disclosed all features in this specification except mutually exclusive feature, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
