Description
Technical field
The utility model relates to benzene hydrogenation section hydrogen devices without interruption.
Background technique
Benzene hydrogenation section, which has, needs hydrogen at two, be hydrogenation reaction at one, and another place is the fuel gas of two heating furnaces.
Hydrogen comes from methanol purge gas, and methanol purge gas is divided into two-way and enters conversion zone, and a routing regulating valve is depressurized to 0.2-0.3Mpa
Fuel gas as two stoves afterwards, another way enter hydrogen generating system after regulating valve is depressurized to 1.8Mpa, and production purity reaches
99.95% or more hydrogen.Therefore, the stability of hydrogenation system largely relies on the stability of methanol purge gas, if
Methanol speeds to shut down, and methanol purge gas stops supplying, and benzene hydrogenation section will therefore must not be not parking without hydrogen.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of devices of hydrogen without interruption, it is ensured that hydrogenation reaction
The supply of section hydrogen.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the utility model is a kind of hydrogen dress without interruption
It sets, including stage compressor, split-compressor, three-stage blower, supercharger and coal gas processing device, the stage compressor is logical
Piping is connect with coal gas processing device, and coal gas processing device is connect by pipeline with split-compressor, split-compressor and three
Grade compressor is connected by pipeline, and three-stage blower is connect by pipeline with device for producing hydrogen, the supercharger and split-compressor
It is connected by pipeline, supercharger is connect by pipeline with heating furnace.
Preferably, the coal gas processing device includes oil removing pot, adsorption tanks, digester and preprocessor, the oil removing pot,
Adsorption tanks, digester and preprocessor are sequentially connected with.
Using the technical solution of the utility model, can obtain it is below the utility model has the advantages that
The hydrogen of the utility model device without interruption is pressurized by three stage compression and passes through the processing of coal gas processing device
Coke-stove gas, which is sent in device for producing hydrogen, afterwards carries out hydrogen manufacturing, and coke-stove gas is continuously transported in device for producing hydrogen by the present apparatus, system
Hydrogen production device continuous work is supplied to hydrogenation process.
Detailed description of the invention
Brief description is made to content expressed by each attached drawing of this specification and the label in figure below:
Fig. 1 is the structural schematic diagram of the present apparatus；
Label in above-mentioned figure is equal are as follows: 1, stage compressor；2, split-compressor；3, three-stage blower；4, oil removing pot；5,
Adsorption tanks；6, digester；7, preprocessor；8, device for producing hydrogen；9, regulating valve；10, supercharger；11, heating furnace.
Specific embodiment
Below against attached drawing, by the description of the embodiment, such as related to specific embodiment of the present utility model
The shape of each component, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle etc. make into
The detailed description of one step.
As shown in Figure 1, this hydrogen device without interruption include stage compressor 1, split-compressor 2, three-stage blower 3,
Supercharger 10 and coal gas processing device, stage compressor 1 are connect by pipeline with coal gas processing device, and coal gas processing device passes through
Pipeline is connect with split-compressor 2, and split-compressor 2 is connect with three-stage blower 3 by pipeline, and three-stage blower 3 passes through pipe
Road is connect with device for producing hydrogen 8, and supercharger 10 is connect with split-compressor 2 by pipeline, and supercharger 10 passes through pipeline and heating furnace
11 connections.
As shown in Figure 1, above-mentioned coal gas processing device includes oil removing pot 4, adsorption tanks 5, digester 6 and preprocessor 7, oil removing
Tank 4, adsorption tanks 5, digester 6 and preprocessor 7 are successively sequentially connected with.
Coke-stove gas is led into this device for producing hydrogen when use, successively by oil removing, suction after the compression of stage compressor 1
Enter split-compressor 2 after attached, desulfurization, pretreatment, then pressurize through split-compressor 2 and three-stage blower 3, final pressure reaches
Coal gas to 1.8Mpa, stage compressor 1 can lead to hydrogen manufacturing with the burning coal gas of supplementary heating furnace, the coal gas of three-stage blower 3
Device 8.Above-mentioned oil removing pot 4 is used to remove the coal tar in coke-stove gas, and adsorption tanks 5 are used to adsorb the steam in coal gas, desulfurization
Tank 6 is used to remove the sulfur-containing compound in coal gas, and preprocessor 7 is for carrying out subsequent hydrogen manufacturing behaviour after pre-processing to coal gas
Make.
With the growth of gas fitting runing time, hydrogen capacity might have decline, also will affect system when in addition overhauling
Hydrogen amount affects the stability of system.Therefore, we separately increase a set of air supply system, which can be by coke-stove gas
It is forced into 0.2-0.3Mpa, when coal gas hydrogen manufacturing amount is inadequate, supercharger 10 is opened and is supplied to heating furnace 11.
