Description
Technical field
The utility model belongs to field of chemical equipment, relates to a kind of solidification chemical product production equipment, particularly relates to a kind of hydrogenation reaction device.
Background technology
Hydrogenated Bisphenol A is a kind of important Chemicals, is widely used in fields such as resin, plastics, rubber, coating.Producing Hydrogenated Bisphenol A is utilize dihydroxyphenyl propane Hydrogenation standby, and therefore hydrogenation unit is very important operating unit.
Traditional hydrogenation unit is the stirring cooking-pot type or the bubbling column reactor that adopt band bubbling pipe, this type equipment needs the unreacted hydrogen hydrogen pump recirculation bubbling of will overflow from liquid level, also to forward completely reacted material pump to strainer during subsequent filter to filter, cause energy consumption high, equipment investment is large, floor space is large, the producer of current domestic production dihydroxyphenyl propane is little, mainly because hydrogenation workshop section yield is low, filtration energy consumption is high, cause production cost higher, quality is more unstable, large-scale production can not be formed, therefore the hydrogenation unit researching and developing Hydrogenated Bisphenol A is the active demand of existing market.
Utility model content
Not enough for prior art, the purpose of this utility model be to provide a kind of structure simple, consume energy low, simple to operate, equipment utilization fully, steady quality, working efficiency be high, is particularly suitable for the device that dihydroxyphenyl propane hydrogenation produces Hydrogenated Bisphenol A.
For realizing the utility model object, this hydrogenation filtration unit comprises material dissolution still, recycle pump, preheater, adds hydrogenous filter, its feature is: material dissolution still adopts the structure of jacketed, in chuck, pass into steam, be connected with hydrogenation filter bottom, recycle pump successively bottom material dissolution still; The recycle pump the other end connects preheater, and preheater is connected with hydrogenation filter top by pipeline; Add hydrogenous filter to be made up of injection circulation reactor, hydrogen pipe, strainer, it is tower for adding hydrogenous filter, respectively is hydroconversion reaction zone, filtrating area from top to bottom in tower inside, and two district's flanges are interconnected and communicate; In hydroconversion reaction zone, hydrogen pipe connects injection circulation reactor, and injection circulation reactor is fixed on tower top, and connects preheater by pipeline; Recycle pump is connected with material cooling reactor.The various import and export pipelines be connected with recycle pump all install by-pass valve control.
Add the pipeline being provided with between hydrogenous filter hydroconversion reaction zone and recycle pump and being with valve, be conducive to the abundant circulating reaction of unnecessary material.
Preheater adopts tubulation structure, and shell side leads to steam heating, and tube side leads to material.
The utility model principle is: raw material is high-temperature digestion in material dissolution still, entered after preheater is heated to temperature of reaction by recycle pump and enter sparge ring stream device, open pressurized with hydrogen hybrid reaction simultaneously, material flows into hydroconversion reaction zone, then to be circulated hydrogenation by recycle pump, the hydroconversion reaction zone be now connected with recycle pump, the valve opening of preheater, all the other are closed.After learning that hydrogenation reaction completes after testing, start filtering catalyst, open the filter outlet, the cooling reactor imported valve that are connected with recycle pump, close other valve, after hydrogenation completes, material is after the strainer of filtrating area, complete catalyst filtration operation, so far complete hydrogenation and the filter progress of a batch materials, then enter subsequent processing.
The beneficial effects of the utility model are: in hydrogenation process, select injection circulation reactor, and hydrogenation is abundant, and yield is high, do not need, to the hydrogen recirculation of effusion, to decrease technical process; Strainer and hydrogenator are an entirety, ensure that condition of high temperature during filtering catalyst, decrease the calorific loss in material transfer process, saved energy consumption; In application particularly in dihydroxyphenyl propane hydrogenation production Hydrogenated Bisphenol A, energy efficient, equipment investment is few, and working efficiency is high, constant product quality, is applicable to industrial application.
Accompanying drawing explanation
Fig. 1 is the utility model hydrogenation filter apparatus configuration schematic diagram, 1 dissolution kettle in figure, 2 recycle pumps, and 3 preheaters, 4 add hydrogenous filter, 5 injection circulation reactors, 6 strainers, 7 hydrogen pipes.
Embodiment
For being described in detail to the utility model better, give an actual example as follows.
Embodiment
This hydrogenation filtration unit comprises material dissolution still 1, recycle pump 2, preheater 3, adds hydrogenous filter 4, its feature is: material dissolution still 1 adopts the structure of jacketed, in chuck, pass into steam, bottom material dissolution still 1 successively with add bottom hydrogenous filter 4, recycle pump 2 is connected; Recycle pump 2 the other end connects preheater 3, preheater 3 by pipeline with add hydrogenous filter 4 top and be connected; Add hydrogenous filter 4 to be made up of injection circulation reactor 5, hydrogen pipe 7, strainer 6, add hydrogenous filter 4 for tower, respectively be hydroconversion reaction zone, filtrating area from top to bottom in tower inside, two district's flanges are interconnected and communicate; In hydroconversion reaction zone, hydrogen pipe 7 connects injection circulation reactor 5, and injection circulation reactor 5 is fixed on tower top, and connects preheater 3 by pipeline; Recycle pump 2 is connected with material cooling reactor.The various import and export pipelines be connected with recycle pump 2 all install by-pass valve control.
Add the pipeline being provided with between hydrogenous filter 4 hydroconversion reaction zone and recycle pump 2 and being with valve, be conducive to the abundant circulating reaction of material.
