Abstract
The invention discloses an anthraquinone method hydrogen peroxide production catalyst protector, relates to the technical field of anthraquinone method hydrogen peroxide production, and especially relates to a catalyst protector. The catalyst proctor comprises a shell, the shell is in sealed connection with an upper manhole and a lower manhole, and the upper manhole is arranged over the lower manhole; and the internal of the shell is fixedly connected with a liquid collector, the liquid collector is provided with an elongate hole, a protection agent is arranged in the shell, the protection agent is arranged over the liquid collector, the shell over the protection agent is provided with a transversely-arranged liquid inlet tube, the liquid inlet is fixedly connected with the shell, the liquid inlet tube in the shell is provided with a dispersion hole, and the bottom of the shell is fixedly connected with a liquid outlet tube communicated with the inner cavity of the shell. The catalyst proctor purifies and filters a regeneration liquid to protect a catalyst.
Description
Technical field
The present invention relates to anthraquinone hydrogen peroxide production technical field, relate in particular to the catalyst protector.
Background technology
The regenerated liquid that existing technical process is the regenerated liquid pump discharge directly enters hydrogenation reactor, load noble metal catalyst 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, have at present following defect in technique:
1, regenerated liquid, through purifying, does not make the organic impurity content in regenerated liquid high, makes the organic impurity content in product high, causes the product total content of organic carbon to rise.
2, the toxic substance in regenerated liquid is not purified, and makes the noble metal catalyst in hydrogenation reactor easily poisoning, and the activity of the noble metal catalyst of reduction even loses activity.
3, the impurity such as the colloid in regenerated liquid and solid particulate matter are not purified, along with regenerated liquid enters noble metal catalyst in hydrogenation reactor, stop up the micropore of catalyst, the activity of noble metal catalyst is descended, the noble metal catalyst regeneration period is shortened, and reduce work-ing life.
4, after the colloid in regenerated liquid and solid particulate matter impurity enter the noble metal catalyst layer, catalyst is scabbed, the resistance of hydrogenation reactor is increased, cause system loading to reduce, affect the output of product.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of anthraquinone hydrogen peroxide production catalyst protector is provided, regenerated liquid is purified and filter to protect catalyst.
The object of the present invention is achieved like this: anthraquinone hydrogen peroxide production catalyst protector, comprise housing, and on housing, be tightly connected top manhole and bottom manhole, the top manhole is arranged on the top of bottom manhole; Be fixedly connected with the liquid manifold in described housing; the long strip shape hole is set on the liquid manifold; protective material is set in housing; protective material is arranged on the top of liquid manifold; the liquid inlet tube of the lateral arrangement of planting on the housing of protective material top; liquid inlet tube is fixedly connected with housing, on the liquid inlet tube in housing, dispersion hole is set, and the bottom of housing is fixedly connected with the liquid outlet tube with the housing intracavity inter-connection.
The present invention, by catalyst protector top, the regenerated liquid liquid-inlet pipe being set, in liquid-inlet pipe interventional instrument housing, and arranges circular dispersion hole on dispersion pipe, and liquid can be evenly distributed.And in the bottom of regenerated liquid liquid-inlet pipe, protective material is set.In protectant bottom, the liquid manifold is set, opens the long strip shape hole on manifold, the long strip shape hole is fluid passage, can prevent that protective material is along with liquid flows out the catalyst protector simultaneously.
The invention has the beneficial effects as follows: 1, by the catalyst protector, purify and filter the organic impurity reduced in regenerated liquid, the quality of the product of raising, make the organic carbon content in product reduce 15-20ppm than traditional technology.
2, regenerated liquid, after the protective material in the catalyst protector purifies, has been removed objectionable impurities in regenerated liquid (S, CL), makes noble metal catalyst that intoxicating phenomenon no longer occur.
3, regenerated liquid is after the protective material in the catalyst protector purifies; reduced the content of colloid and solid particulate matter in the 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 use simultaneously.
4, make regenerated liquid obtain purification, improved the cleanliness factor of regenerated liquid, catalyst is no longer lumpd, the resistance in hydrogenation reactor no longer increases, and has improved the production capacity of production equipment.
The 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 long strip shape holes.
Embodiment
As shown in Figure 1, for anthraquinone hydrogen peroxide production catalyst protector, comprise housing 1, close soldered section's manhole 2 and the bottom manhole 4 of connecting on housing 1, top manhole 2 is arranged on the top of bottom manhole 4.The interior welding liquid of housing 1 manifold 5; long strip shape hole 9 is set on liquid manifold 5; the interior protective material 3 that arranges of housing 1; protective material 3 is arranged on the top of liquid manifold 5; the liquid inlet tube 6 of the lateral arrangement of planting on the housing 1 of protective material 3 tops; liquid inlet tube 6 and housing 1 welding, arrange dispersion hole 8, the liquid outlet tube 7 of the bottom welding of housing 1 and housing 1 intracavity inter-connection on the liquid inlet tube 6 in housing 1.
Claims (1)
1. anthraquinone hydrogen peroxide production catalyst protector is characterized in that: comprise housing, and on housing, be tightly connected top manhole and bottom manhole, the top manhole is arranged on the top of bottom manhole; Be fixedly connected with the liquid manifold in described housing; the long strip shape hole is set on the liquid manifold; protective material is set in housing; protective material is arranged on the top of liquid manifold; the liquid inlet tube of the lateral arrangement of planting on the housing of protective material top; liquid inlet tube is fixedly connected with housing, on the liquid inlet tube in housing, dispersion hole is set, and the bottom of housing is fixedly connected with the liquid outlet tube with the housing intracavity inter-connection.
