Background technique
In present human society, many substances are processed by chemical reaction, and anti-in certain chemistry
Answering middle fixed bed reactors is a very important consersion unit, and its advantages are：1. back-mixing is small, fluid can be into catalyst
Row effectively contact can obtain more highly selective when reaction is with series connection side reaction.2. catalytic mechanical loss is small.3. structure is simple
It is single.The shortcomings that fixed bed reactors is：Poor heat transfer, when exothermic heat of reaction amount is very big, even shell and tube reactor may also occur
Temperature runaway（Reaction temperature is out of hand, steeply rises, and is more than allowed band）It will if adding cooling device to shell and tube reactor
Reaction effect can be substantially improved, but is that cannot directly be heated by electric current in reactor.

Temperature-controllable ensure that being normally carried out and avoiding security risk caused by high temperature for reaction.
Detailed description of the invention
Fig. 1 is utility model diagram.
In figure：It is reaction kettle 1, feed(raw material)inlet 2, product exit 3, motor 4, tubulation 5, branch pipe 6, evaporator 7, compressor 8, cold
Solidifying pipe 9, heating power expansion valve 10.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of calandria type fixed bed reaction for alkynes
Device, including reaction kettle 1 are provided with feed(raw material)inlet 2 above reaction kettle 1, and 1 bottom of reaction kettle is provided with product exit 3, raw material
Several motors 4 are provided with below entrance 2, and motor 4 has been respectively fixedly connected with tubulation 5, several branch are provided in tubulation 5
Pipe 6,1 right side inner wall of reaction kettle is provided with evaporator 7, and 7 lower end of evaporator passes through 8 left end entrance of pipeline connect compressor
Seat, 8 right end outlet port of compressor is connected with condenser pipe 9, and condenser pipe 9 connects heating power expansion valve 10 by pipeline, and heating power is swollen
Swollen valve 10 connects 7 upper end of evaporator by pipeline.
Further, tubulation 5 and 6 surface of branch pipe are uniformly covered with hole, and the branch pipe on adjacent tubulation 5 is set in dislocation
It sets, it is hinged in 1 inner wall of reaction kettle that 5 upper and lower ends of tubulation pass through bearing；
Further, feed(raw material)inlet 2 offers several branch mouths, and inside branch mouth intercalation reaction kettle 1, branch mouth with react
Kettle joint is provided with sealing ring；
Further, heating power expansion valve 10 is arranged close to 7 upper end of evaporator, and valve body is disposed vertically.
Working principle：Reaction raw materials are put into reaction kettle 1 by feed(raw material)inlet 2, the tubulation 5 inside reaction kettle 1 and branch
Catalyst is filled up in pipe 6, tubulation 5 rotates under the drive of motor 4, so that reaction raw materials is adequately exposed to catalyst and accelerates instead
Rate is answered, and internal reaction can generate high temperature therewith, the low-pressure, liquid refrigerant in evaporator 7 absorbs internal temperature and steams at this time
Low-pressure gaseous refrigerant is sent out into, subsequent low-pressure gaseous refrigerant reaches compressor 8 by pipeline, and low-pressure gaseous refrigerant can be pressed
Shorten high-pressure gaseous refrigerant into, high-pressure gaseous refrigerant subsequently flows into condenser pipe 9 and passes through extraneous sub-cooled into high-pressure liquid system
