Abstract
Anthraquinone method hydrogen peroxide production catalyst protector, relates to anthraquinone Hydrogen Peroxide Production technical field, particularly relates to catalyst protector, comprise housing, and housing is tightly connected top manhole and bottom manhole, and top manhole is arranged on the top of bottom manhole; Described housing internal fixtion connects liquid manifold; liquid manifold arranges elongate holes; in housing, protective material is set; protective material is arranged on the top of liquid manifold; the liquid inlet tube of a lateral arrangement that the housing above protective material is planted; liquid inlet tube is fixedly connected with housing, and the liquid inlet tube in housing arranges dispersion hole, and the bottom of housing is fixedly connected with the liquid outlet tube be connected with housing cavity.The present invention purifies regenerated liquid and filters to protect catalyst.
Description
Technical field
The present invention relates to anthraquinone Hydrogen Peroxide Production technical field, particularly relate to catalyst protector.
Background technology
Existing technical process is that the regenerated liquid of regenerated liquid pump discharge directly enters hydrogenation reactor, noble metal catalyst is loaded in hydrogenation reactor, 2-ethyl-anthraquinone under certain pressure and temperature in hydrogen and regenerated liquid carries out hydrogenation reaction, generate 2-ethyl hydrogen anthraquinone, in current technique, there is following defect:
1, regenerated liquid is not through purification, makes the organic impurity content in regenerated liquid high, makes the organic impurity content in product high, cause product total content of organic carbon to rise.
2, the toxic substance in regenerated liquid is not purified, and make the noble metal catalyst in hydrogenation reactor easily poisoning, the activity of the noble metal catalyst of reduction even loses activity.
The impurity such as the colloid 3, in regenerated liquid and solid particulate matter are not purified, along with regenerated liquid enters noble metal catalyst in hydrogenation reactor, the micropore of blocking catalyst, makes the activity decrease of noble metal catalyst, the noble metal catalyst regeneration period is shortened, and work-ing life reduces.
4, after the colloid in regenerated liquid and solid particulate matter impurity enter noble metal catalyst layer, catalyst is scabbed, the resistance of hydrogenation reactor is increased, causes system loading to reduce, affect the output of product.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, to provide a kind of Anthraquinone method hydrogen peroxide production catalyst protector, regenerated liquid being purified and filters to protect catalyst.
The object of the present invention is achieved like this: Anthraquinone method hydrogen peroxide production catalyst protector, comprises housing, and housing is tightly connected top manhole and bottom manhole, and top manhole is arranged on the top of bottom manhole; Described housing internal fixtion connects liquid manifold; liquid manifold arranges elongate holes; in housing, protective material is set; protective material is arranged on the top of liquid manifold; the liquid inlet tube of a lateral arrangement that the housing above protective material is planted; liquid inlet tube is fixedly connected with housing, and the liquid inlet tube in housing arranges dispersion hole, and the bottom of housing is fixedly connected with the liquid outlet tube be connected with housing cavity.
The present invention is by arranging regenerated liquid liquid-inlet pipe on catalyst protector top, and liquid-inlet pipe inserts in apparatus casing, and on dispersion pipe, arrange circular dispersion hole, and liquid is evenly distributed.And protective material is set in the bottom of regenerated liquid liquid-inlet pipe.Arrange liquid manifold in protectant bottom, manifold opens elongate holes, elongate holes is fluid passage, and protective material can be prevented along with liquid outflow catalyst protector simultaneously.
The invention has the beneficial effects as follows: 1, purify and filter the organic impurity reduced in regenerated liquid by catalyst protector, the quality of the product of raising, make the organic carbon content comparatively traditional technology reduction 15-20ppm in product.
2, regenerated liquid is after the protective material purification in catalyst protector, removes objectionable impurities in regenerated liquid (S, CL), makes noble metal catalyst no longer intoxicating phenomenon occur.
3, regenerated liquid is after the protective material purification in catalyst protector; reduce the content of colloid and solid particulate matter in regenerated liquid; cleaner when regenerated liquid enters hydrogenation reactor, the regeneration period of the noble metal catalyst of prolongation and work-ing life, saved the water vapor of a large amount of regeneration simultaneously.
4, make regenerated liquid obtain purification, improve the cleanliness factor of regenerated liquid, catalyst is no longer lumpd, the resistance in hydrogenation reactor no longer increases, and improves the production capacity of production equipment.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
In figure, 1 housing, 2 top manholes, 3 protective materials, 4 bottom manholes, 5 liquid manifolds, 6 liquid inlet tubes, 7 liquid outlet tubes, 8 dispersion hole, 9 elongate holes.
Embodiment
As shown in Figure 1, be Anthraquinone method hydrogen peroxide production catalyst protector, comprise housing 1, closely on housing 1 solderedly connect portion's manhole 2 and bottom manhole 4, top manhole 2 is arranged on the top of bottom manhole 4.Welding liquid manifold 5 in housing 1; liquid manifold 5 is arranged elongate holes 9; protective material 3 is set in housing 1; protective material 3 is arranged on the top of liquid manifold 5; the liquid inlet tube 6 of a lateral arrangement that the housing 1 above protective material 3 is planted; liquid inlet tube 6 welds with housing 1, and the liquid inlet tube 6 in housing 1 arranges dispersion hole 8, the bottom welding of housing 1 and the liquid outlet tube 7 of housing 1 intracavity inter-connection.
Claims (1)
