Description
Technical field
The utility model relates to a kind of synthesis reactor, and endless tube intercommunication type synthesis reactor especially can be used for the occasion of the chemical products such as methyl alcohol is synthetic.
Background technology
At present, generally adopt at home the cold-tube type synthesis reactor in the chemical enterprise, enter collection chamber at this reactor Raw gas by central tube, then enter into again cold pipe through air entraining pipe, upper endless tube.Usually, for ease of producing, the latus rectum of air entraining pipe is consistent, again because the limited space of collection chamber, so that the unstripped gas that enters into collection chamber from central tube when in collection chamber, evenly not distributing by air entraining pipe through on endless tube enter into descending cold pipe, and after lower endless tube commutation, enter into catalyst layer by up cold pipe and carry out synthetic reaction.Entering into the unstripped gas of cold pipe because unstripped gas evenly distributes in collection chamber by air entraining pipe can not uniform distribution, thereby the unstripped gas that causes entering into cold pipe can not shift the heat that synthetic reaction produces equably, finally cause the temperature difference on the conversion zone sagittal plane larger, thereby affect the combined coefficient of reactor.For the synthetic occasion of low pressure methanol, although air inlet is positioned at the end of end socket, but exist equally unstripped gas skewness and unstripped gas of entering in the cold tube bag in collection chamber can not shift equably the heat that produces in the synthetic reaction, cause the temperature difference on the conversion zone sagittal plane larger.
The utility model content
The utility model provides the unstripped gas in a kind of cold pipe to be evenly distributed for the deficiencies in the prior art, and the conversion zone sagittal plane has a narrow range of temperature, the synthesis reactor that the unstripped gas combined coefficient is high.
For realizing above goal of the invention, the utility model by the following technical solutions:
A kind of endless tube intercommunication type synthesis reactor, comprise upper cover plate 1, dividing plate 2, cylindrical shell 3, cold tube bag 4, the internal cavities of upper cover plate 1 and dividing plate 2 consist of collection chamber, cold tube bag 4 comprises air entraining pipe 7, upper endless tube 5, lower endless tube 6, descending cold pipe 8 and up cold pipe 9, upper endless tube 5 is communicated with respectively with an end of air entraining pipe 7, descending cold pipe 8, lower endless tube 6 is communicated with respectively with the other end of descending cold pipe 8, an end of up cold pipe 9, cold tube bag 4 coaxial hearts are set in the cylindrical shell 3, are interconnected between the same layer endless tube of the cold tube bag 4 of concentric suit.
As one of technique scheme example preferably, be interconnected between the upper endless tube 5 of the cold tube bag 4 of described concentric suit.
As another example preferably of technique scheme, be interconnected between the lower endless tube 6 of the cold tube bag 4 of described concentric suit.
As another example preferably of technique scheme, be interconnected by straight tube between the endless tube of the cold tube bag 4 of described concentric suit.
As another example preferably of technique scheme, be interconnected by U-shaped pipe 10 between the lower endless tube 6 of the cold tube bag 4 of described concentric suit.
The beneficial effects of the utility model are, after carrying out substantial improvements by the cold tube bag to reactor, can effectively guide the flow direction of unstripped gas, unstripped gas is distributed in the cold pipe equably, thereby can shift equably the heat that produces in the synthetic reaction, the conversion zone sagittal plane temperature difference is reduced, greatly improve the combined coefficient of unstripped gas, prolong catalyst life.
Description of drawings
Accompanying drawing is the structural representation of endless tube intercommunication type synthesis reactor.
The specific embodiment
In the embodiment shown in the figures, a kind of endless tube intercommunication type synthesis reactor comprises upper cover plate 1, dividing plate 2, cylindrical shell 3, cold tube bag 4; On the cylindrical shell 3 gas outlet is arranged; The internal cavities of upper cover plate 1 and dividing plate 2 consist of collection chamber; Cold tube bag 4 comprises air entraining pipe 7, upper endless tube 5, lower endless tube 6, descending cold pipe 8 and up cold pipe 9; Pass through packing box seal between air entraining pipe 7 and the dividing plate 2; Upper endless tube 5 directly is communicated with respectively with an end of air entraining pipe 7, descending cold pipe 8, and lower endless tube 6 directly is communicated with respectively with an end of the other end of descending cold pipe 8, up cold pipe 9; Cold tube bag 4 coaxial hearts are set in the cylindrical shell 3, can be set with according to the diameter of reactor 2 layers, 3 layers even more multi-layered; Be interconnected between the same layer endless tube of the cold tube bag 4 of concentric suit.Described " with being interconnected between the layer endless tube " refers to be interconnected between the endless tube 5 or between the lower endless tube 6.In specifically using, be interconnected between the upper endless tube 5 of the cold tube bag 4 of concentric suit, or be interconnected between the lower endless tube 6, or simultaneously respectively connection between the upper endless tube 5, between the lower endless tube 6; Connection between the endless tube is that straight tube is communicated with, but is communicated with as good the stress that produces to eliminate thermal deformation take U-shaped pipe 10.
Unstripped gas is from bottom to top flowed by central tube, entering unstripped gas behind the collection chamber enters into upper endless tube 5 and is assigned to descending cold pipe 8 after air entraining pipe 7 guiding, after 6 commutations of lower endless tube, enter in the up cold pipe 9, go out to enter catalyst layer behind the up cold pipe 9 and carry out synthetic reaction.Owing to be interconnected between the same layer endless tube of the cold tube bag 4 in the utility model, can effectively guide the flow direction of unstripped gas, realize the unstripped gas uniform distribution between each cold pipe, thereby the heat that synthetic reaction produces in the transfer reaction layer equably, reduce isoplanar radial temperature difference in the conversion zone, the efficient of Effective Raise synthetic reaction, the service life of prolongation catalyst.
For the low pressure methanol synthesis reactor, upper cover plate 1 namely is the upper cover with air inlet, and at this moment, unstripped gas enters reactor by the air inlet on the upper cover.Need not to arrange central tube in the reactor.
