After shunting, after uniformly flowing into the reacting gas heat exchange in second channel 121, with first passage 111, enter the 4th receiving chamber 290,
After the pooling from heat exchange outlet 250 outflow.
Heat in first passage 111 can be used for preheating reacting gas by such consersion unit 200 makes reacting gas
Enter in first passage 111 contact with catalyst 360 before just can reach the temperature that preferably feeds, improve reactivity,
Accelerate reaction rate.
Embodiment 4
Refer to Fig. 8, the present embodiment provides a kind of consersion unit 200, and it is roughly the same with the 3rd embodiment, the district of the two
It is not that the consersion unit 200 of the present embodiment includes four reaction units 100, and in housing 210, does not possess third channel 330.
First passage 111 and second channel 121 are arranged in 90 degree of angles.Each reaction unit 100 is respectively provided with one
220, reactant 230, heat exchange import 240 of outlet of reaction-ure inlet and a heat exchange outlet 250.With embodiment three not
With, reaction-ure inlet 220 and reactant outlet 230 are not located at the axial two ends of housing 210.At the present embodiment
In, reaction-ure inlet 220 and reactant outlet 230 are oppositely disposed at the radial direction of housing 210.Reaction-ure inlet 220 He
Reactant outlet 230 two ends with first passage 111 respectively are connected.
It should be noted that reaction-ure inlet 220, reactant outlet 230, heat exchange import 240, heat exchange outlet 250
To be respectively provided with 4, it is also possible to after collecting in housing, it is respectively provided with 1.
Such consersion unit 200, because having multiple reaction unit 100, both can ensure multiple batches of and/or many simultaneously
The reactant simultaneous reactions of kind, which enhances the utilization rate of consersion unit 200, it is also possible to expand the place of consersion unit 200
Reason scale, meets the chemical plant installations requirement that scale expands increasingly.
In sum, the reaction unit 100 in the embodiment of the present invention has the multiple reaction members 110 being crisscross arranged with many
Individual heat exchange unit 120, and be connected by heat exchanger plates 130 between reaction member 110 with heat exchange unit 120, such reaction member 110
The heat of middle generation or needs can be transmitted by heat exchanger plates 130 to second channel 121 or obtain, so that first passage 111
In reacting gas reaction time can maintain a more stable temperature all the time, improve reactivity and reaction selectivity.First
Being provided with the first fin 112 in passage 111, first passage 111 is divided into multiple long and narrow reaction runner by the first fin 112,
Reaction mass flow velocity in each long and narrow reaction runner is very fast, and diffusional resistance is little, and reaction rate is fast, and close to preferable horizontal sliding
Stream, decreases material back-mixing, improves reaction efficiency.
Consersion unit 200 includes the reaction dress with multiple reaction members 110 and multiple heat exchange unit 120 being crisscross arranged
Put 100.Reaction is arranged device in the airtight housing 210 of hollow, housing 210 is provided with reaction-ure inlet 220, reaction
Thing outlet 230, heat exchange import 240 and heat exchange outlet 250.Separate first is formed between reaction unit 100 and housing 210
Accommodate chamber 260, second and accommodate receiving chamber, chamber the 270, the 3rd 280 and the 4th receiving chamber 290, the most both met fluid and be uniformly distributed
Require and runner sealing requirements, make again consersion unit to be attached with other devices or equipment easily.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
