Description
（One）Technical field
A kind of Local Members of ammonia convertor are the utility model is related to, more particularly to a kind of ammonia convertor cold shock conductance stream dress
Put.
（Two）Background technology
Synthesis ammonia refers to the ammonia directly synthesized in the presence of the catalyst at elevated temperature and pressure by nitrogen and hydrogen, is a kind of substantially inorganic
Chemical-process.In modern chemical industry, ammonia is the primary raw material of chemical fertilizer industry and basic organic chemical industry, is occupied in national economy
Critical role, it is used for producing chemical fertilizer wherein there are about 80% ammonia, 20% is the raw material of other chemical products.Ammonia convertor is referred to as
The heart of synthesis ammonia plant, it is one of chief equipment in whole synthesis ammonia plant production process.
In chemical industry, the ammonia conversion ratio of conventional synthesis tower is relatively low（10%~12%）, synthesis pressure is higher（22.0 MPa
~32.0MPa）, energy consumption of unit product is very high.Later because purification techniques improves, gas componant improves, foreign gas content is by 1%
~5% drops to 10ppm~50ppm, and the structure of synthetic tower is also changed, and increases heat exchange area between catalyst section, reduces
Synthesis mean temperature, therefore, the ammonia conversion ratio of synthetic tower improve（15%~18%）, synthesis pressure reduction（12.0 MPa~
15.0MPa）, energy consumption of unit product is decreased obviously.But synthesis pressure is still above 10MPa, more than 10 Mpa for synthesis
For tower, difficulty of processing is big, high processing costs, operating risk are high, and operation energy consumption is also high.For synthesizing ammonia, reaction temperature
Degree is lower, and its conversion ratio is higher, also low to horsepower requirements, but synthesizes the process that ammonia is very exothermic, and there is presently no solution
The equipment of its Fast exothermic.
（Three）The content of the invention
The utility model is in order to make up the deficiencies in the prior art, there is provided one kind cooling efficiency high, it is simple in construction, reduce energy
The ammonia convertor cold shock gas guiding device of consumption.
The utility model is achieved by the following technical solution：
A kind of ammonia convertor cold shock gas guiding device, including the cold shock gas house steward stretched into ammonia convertor, it is characterized in that：Institute
State cold shock gas house steward and connect some cold shock qi leel stringings, cold shock qi leel stringing is stretched into dispersion pipe, and dispersion pipe middle and lower part is connected with
Disperse branch pipe, dispersion hole is offered on dispersion pipe and scattered branch pipe, some baffle plates are provided with inside dispersion pipe.
The dispersion pipe top is provided with gas dispersion plate.
The beneficial effects of the utility model are：Cold shock gas can be made to rapidly enter the various pieces of ammonia synthesis heat exchangers in towers,
Make simultaneously effective to be cooled inside heat exchanger, greatly improve ammonia synthesis conversion ratio, while reduce synthesis pressure and energy
Consumption, the difficulty of processing of equipment is reduced, more securely and reliably.
（Four）Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Accompanying drawing 1 is structural representation of the present utility model；
In figure, 1 cold shock gas house steward, 2 cold shock qi leel stringings, 3 dispersion pipes, 4 scattered branch pipes, 5 dispersion holes, 6 baffle plates, 7 gases
Dispersion plate.
（Five）Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.The cold shock gas that the embodiment includes stretching into ammonia convertor is total
Pipe 1, cold shock gas house steward 1 connect some cold shock qi leel stringings 2, and cold shock qi leel stringing 2 is stretched into dispersion pipe 3, the middle and lower part of dispersion pipe 3
Scattered branch pipe 4 is connected with, dispersion hole 5 is offered on dispersion pipe 3 and scattered branch pipe 4, the inside of dispersion pipe 3 is provided with some baffle plates 6.Point
The top of separate tube 3 is provided with gas dispersion plate 7.
Using a kind of ammonia convertor cold shock gas guiding device of the present utility model, ammino is monitored by the temperature sensor moment
Temperature in into tower, when temperature is higher, cold shock gas is set to enter each cold shock qi leel stringing 2 so that cold shock by cold shock gas house steward 1
Gas covers the whole plane of ammonia convertor, and then enters the whole vertical direction of ammonia convertor by dispersion pipe 3, then by disperseing branch pipe
4 enter each plane of ammonia convertor vertical direction, are discharged by dispersion hole 5, because more down temperature is lower, so baffle plate 6
Can suitable control cold shock gas enter lower section amount.
