Abstract
The utility model relates to a 1,4-butanediol internal heat exchange-type high-pressure hydrogenation reactor. The 1,4-butanediol internal heat exchange-type high-pressure hydrogenation reactor comprises a main reactor (1), wherein a heat exchanger (3) is arranged at the bottom of the main reactor (1), and the heat exchanger (3) is located in the main reactor (1).

Description
Technical field
The utility model relates to a kind of high-pressure hydrogenation reactor, relates in particular to BDO internal heat exchange type high-pressure hydrogenation reactor.
Background technology
At present, the BDO hydrogenation adopts the fixed bde catalyst high-pressure reactor, by main and auxiliary reactor, forms (seeing accompanying drawing 1)., owing to being hydrogenated to exothermic reaction,, for reaction heat is removed, usually on main reaction liquid phase circulation pipeline, cooler is set, to reduce the temperature of reaction response device inside.In addition,, because the reacting dose in auxiliary reactor is very little, can not reach the needed temperature of reaction, deliver on the liquid phase pipeline of auxiliary reactor and need again to arrange heater, to improve the temperature of auxiliary reactor.Therefore, common BDO high-pressure hydrogenation reactor need to adopt the high pressure heat exchanger of two costlinesses, has increased the input of equipment, has improved production cost.And the reaction liquid phase need to first carry out coolingly, then heats again, designs very unreasonablely, increases the needed energy consumption of whole reaction.
Summary of the invention
It is not enough and propose that the utility model is high for the cost that existing BDO high-pressure hydrogenation reactor has, energy consumption is large etc., aims to provide the BDO internal heat exchange type high-pressure hydrogenation reactor that cost is low, simple in structure, heat exchange efficiency is high.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
BDO internal heat exchange type high-pressure hydrogenation reactor, comprise main reactor, and the main reactor bottom is provided with heat exchanger, and heat exchanger is positioned at main reactor inside.Utilize the free space of main reactor low head, it is built-in heat exchanger that cooling coil is set, and does not need to increase high pressure heat exchanger, has saved expensive equipment investment.
As preferably, heat exchanger is coil pipe.Coil pipe has increased the film-cooled heat of heat exchanger, improves cooling effectiveness.
, as preferably, be provided with cooling fluid in heat exchanger.Use liquid as cooling fluid, have nontoxic, good heat conductivity, the advantage such as not volatile.
As preferably, cooling fluid is cooling water.The cooling water nontoxic pollution-free, and not volatile, and cooling effectiveness is high, reusable edible.
, as preferably, be provided with the Hydrogen distribution device above heat exchanger.Hydrogen enters main reactor by the Hydrogen distribution device, after exothermic reaction occurs, for reaction heat is removed, but does not affect whole reaction, so the Hydrogen distribution device is arranged on the top of heat exchanger.
As preferably, main reactor directly is connected with auxiliary reactor by the liquid phase circulation pipe.Deliver to the liquid phase of auxiliary reactor from the main reactor top, temperature is higher, does not need separately to establish heater, has both saved equipment investment, has saved again energy consumption.
According to the technical solution of the utility model, BDO internal heat exchange type high-pressure hydrogenation reactor adopts coil pipe as built-in heat exchanger, and is not only simple in structure, also facilitated operation and the maintenance in later stage.And utilize cooling water as cooling fluid, improved cooling efficiency.Simultaneously, cooling water can also be cycled to repeat utilization, has reduced cooling cost.In addition, the high-temperature liquid-phase that produces in main reactor is directly sent into auxiliary reactor by the liquid phase circulation pipe, saved the high pressure heat exchanger of two costlinesses, reduced the investment of equipment, reduced cost, also saved energy consumption simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
BDO internal heat exchange type high-pressure hydrogenation reactor, comprise main reactor 1, and main reactor 1 bottom is provided with heat exchanger 3, and heat exchanger 3 is positioned at main reactor 1 inside.Utilize the free space of main reactor 1 low head, it is built-in heat exchanger 3 that cooling coil is set, and does not need to increase high pressure heat exchanger, has saved expensive equipment investment.
Be provided with cooling fluid in heat exchanger 3.Use liquid as cooling fluid, have nontoxic, good heat conductivity, the advantage such as not volatile.
Cooling fluid is cooling water 6.Cooling water 6 nontoxic pollution-frees, and not volatile, and cooling effectiveness is high, reusable edible.
Hydrogen enters main reactor 1 inside from hydrogen inlet 8, when hydrogen is exported from Hydrogen distribution device 5, exothermic reaction occurs, and bottom produces heat and absorbed by heat exchanger 3, reaches cooling effect, and the heat that top produces is along with liquid phase is discharged from main reactor 1 top.Part liquid phase is directly sent into auxiliary reactor 2, makes auxiliary reactor 2 not need to heat the temperature that can reach needs; Another part liquid phase is transferred go back to main reactor 1 bottom and recycles, and this moment, liquid phase process heat exchanger 3, made heat be absorbed by heat exchanger 3.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
