Description
Technical field
The utility model is related to a kind of fuel gas and the mixer of combustion-supporting gas, concretely relate to a kind of synthesis gas
The mixer of (alkene) and oxygen, the mixer can be applied to the production of ethylene glycol (ethylene oxide).
Background technology
Ethylene glycol is important industrial chemicals and strategic materials, and (terylene, beverage can be further produced for manufacturing polyester
Bottle, film), explosive, glyoxal, and antifreezing agent, plasticizer, hydraulic fluid and solvent etc. can be made." coal-ethylene glycol " is i.e. with coal
Instead of oil ethylene production ethylene glycol.It is special that such technology path meets China's oil starvation, few gas, the resource of coal resources relative abundance
Point.In the oxalate synthesis unit of coal-ethylene glycol, to solve synthesis gas and hydroxide reaction is added to require, add in appropriate oxygen；It is mixed
During conjunction, the part of oxygen concentration is excessively high, can cause the local reaction of oxygen and synthesis gas；Reaction causes oxygenation to fail, from
And so that main reaction region lacks oxygen, it is excessively high to also result in oxygenation spot temperature, causes internals ablation, pipeline hot-spot etc.,
When serious, explosion accident can be caused.
Ethylene oxide (EO) is the important chemical products that polyethylene is only second in ethylene industry downstream derivative object, is mainly used for
Produce the production of the fine chemistry industries such as nonionic surface active agent, ethanol amine, glycol ether, polyether polyol, choline chloride and medicine
Product.Current ethylene oxide synthesis is mainly obtained by the reaction by ethylene and oxygen, has to complete ethylene and oxygen before reaction
The mixing of gas, and explosion section is passed through during ethylene and oxygen mix, if control is improper easily to occur blast accident.Cause
This must assure that alkene and explosion section separate after oxygen mix, while ensure in mixed process as possible uniformly, to compress as far as possible
The range of flammable area.
105214528 A of patent CN " mixer of a kind of alkene and oxygen " disclose the mixing of a kind of alkene and oxygen
The problem of device, the mixer is high there are oxygen distribution center regional concentration, and peripheral regions concentration is low；Due to being individual layer arrangement,
During actual processing, it may appear that individual layer oxygen manifold is because can not excessively be processed implementation；
Utility model content
Based on above-mentioned technical problem, the utility model provides the mixer of a kind of synthesis gas alkene and oxygen.
Technical solution is used by the utility model：
A kind of fuel gas and oxygen mixer, the mixer including being used for fuel gas channel are responsible for and for being distributed oxygen
The distributor of gas, distributor include oxygen inlet pipeline, oxygen outer endless tube, oxygen distribution arms, oxygen distribution hole, wherein, oxygen
The outer endless tube of gas is arranged on the outside of mixer supervisor, and connection oxygen distribution arms stretch into mixer master at the inner wall of the outer endless tube of oxygen
Pipe, and oxygen distribution arms are equipped with oxygen distribution hole, and one or more pairs of oxygen inlet pipes are connected at the outer wall of the outer endless tube of oxygen
Road.
Further, oxygen inlet pipeline is symmetrically distributed on the outer endless tube of oxygen.
Further, oxygen distribution arms are symmetrically uniformly distributed stretches into mixer supervisor, and oxygen distribution arms are using length
Short different pipeline.
Further, oxygen distribution arms using make on mixer supervisor section equally distributed that one is long and the other is short is adjacent
Arrangement.
Further, it is evenly equipped with oxygen distribution hole in oxygen distribution arms, the gross area of the oxygen distribution hole≤
1-1.5 times of oxygen inlet pipeline equivalent section product.
Further, the outer endless tube of oxygen, the equivalent diameter of a diameter of 2 times of oxygen inlet pipelines.
Further, flowmeter and internally piloted valve are provided on oxygen inlet pipeline and mixer supervisor.
The utility model has remarkable advantage compared with the prior art：
1st, the mixing of oxygen and fuel gas is more uniform, has prevented what former mixer center region oxygen concentration height caused
Into internals because of temperature ablation the problem of.
2nd, except distributed pipeline is inside inflammable gas pipeline, endless tube and oxygen inlet reduce outside fuel gas
The flow resistance of fuel gas.
3rd, processing and fabricating, installation is simple and convenient, easy to implement.
Description of the drawings
Fig. 1 is the internal structure schematic diagram of the utility model.
Fig. 2 is the schematic diagram that the mixer of the utility model is responsible for.
In figure：1st, mixer is responsible for；2nd, oxygen inlet pipeline；3rd, the outer endless tube of oxygen；4th, oxygen distribution arms；5th, oxygen point
Cloth hole.
Specific embodiment
As shown in Figure 1, 2, mixer includes mixer 1 (fuel gas channel) of supervisor, the outer endless tube 3 of oxygen；Oxygen is distributed
Branch pipe 4 forms.1 end of mixer supervisor may be used flange and be connect with main pipeline, can also use welding form and main pipeline
Connection；
Oxygen distribution arms 4 are symmetrically distributed on mixer and are responsible on 1 outer wall；One is long and the other is short for adjacent oxygen distribution arms 4
It is alternately distributed.
Oxygen distribution arms 4 have N branch according to the diameter that mixer is responsible for；(general N >=4)；
Oxygen distribution arms 4, along oxygen outside 3 inner ring normal direction of endless tube；It is directed toward mixer and is responsible for 1 axis direction；With mixing
It is vertical that clutch is responsible for 1 axis；
Mixer supervisor 1 is mounted on fuel gas supervisor, oxygen inlet pipeline 2 is connected with external oxygen pipeline；
