Abstract
The utility model provides a bushing type methanol or ammonia reactor which can reliably control the catalyzing bed layer temperature of the reactor, enables the catalyzing bed layer temperature distribution to be similar to the ideal kinetics condition, and has high synthesizing efficiency, easy manufacture and low cost. The bushing type methanol or ammonia reactor comprises a cavity body the outside of which is provided with a bushing; catalyzer is filled in the cavity body to form the catalyzing bed layer, and the upper part of the cavity body is provided with an upper header pipe and the lower part is provided with a lower header pipe; the upper part of the bushing is provided with an upper header, and the lower part is provided with a lower header.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, is specifically related to a kind of bushing type methyl alcohol or ammonia reactor.
Background technology
Present widely used cold shocking type methyl alcohol or ammonia reactor, though have his own strong points, all there are the shortcoming that can't overcome separately in shell pipe type methanol reactor and cold-tube type methyl alcohol or ammonia reactor.Cold shocking type methanol reactor temperature is sensitive inadequately, temperature fluctuation will occur inevitably, and circulation power consumption is bigger.Shell pipe type methanol reactor packing factor is little, and Machine Design requires high, and manufacture difficulty is big, the equipment cost height.The beds temperature difference of cold-tube type methanol reactor is big, the bad control of temperature, and overheating problem happens occasionally, and is not easy to operate, and conversion ratio is not high.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, provide a kind of and can reliably control the reactor catalysis bed temperature, it is close with ideal power condition that reaction bed temperature is distributed, and it is high and easy to manufacture to reach combined coefficient, bushing type methyl alcohol or ammonia reactor that cost is low.
The technical solution of the utility model is: a kind of bushing type methyl alcohol or ammonia reactor, comprise cavity, described cavity is provided with sleeve pipe outward, loading catalyst in this cavity, constitute catalytic bed, cavity top is provided with the upper header pipe, and the bottom is provided with the lower collecting box pipe, sleeve pipe top is provided with upper header, and the bottom is provided with lower collecting box.
Described cavity can be two or more, and the upper header pipe and the lower collecting box pipe of each cavity are interconnected respectively, and a plurality of cavitys are coupled together, and the upper header and the lower collecting box of each sleeve pipe are interconnected respectively, and a plurality of sleeve pipes are coupled together.
During the utility model work, introduce saturation water with lower collecting box earlier, make reactor be in design temperature, synthetic raw gas enters cavity from the upper header pipe, after the catalytic bed reaction, go out reactor through the lower collecting box pipe, the water of being introduced by lower collecting box is emitted heat of vaporization by catalytic reaction and is formed steam water interface, enters drum after going out reactor by upper header.
The reaction heat that saturation water in the sleeve pipe produces in the time of can removing the catalytic bed reaction, and water side thermal resistance is less, the cavity internal volume is also less, so bed temperature mainly is to be controlled by the temperature of saturation water, makes the bed temperature isothermal substantially vertically that distributes.The temperature of saturation water can be regulated by the control steam pressure.
The saturation water explosive evaporation produces the steam of elevated pressures, can be used for the place of steam heating, and heat energy obtains utilizing.
A plurality of cavitys can become square formation to arrange, and form several unit, and header tube between each unit or header are opened or closed by valve control, and the valve that can close certain unit is catalyst changeout more, and does not influence other cell operation.
The beneficial effects of the utility model are:
1, the ideal power of reactor batch temperature distribution and methyl alcohol or ammonia synthesis reaction condition is close, makes reactor have high conversion ratio;
2, reactor catalyst easily reduces, and does not have overheated danger;
3, temperature control is sensitive reliable;
4, reclaim reaction heat with higher potential energy, heat energy utilization is reasonable;
5, can realize the more catalyst changeout that do not stop;
6, the equipment processing and manufacturing is easy, and cost is low, uses easy to maintenance, safe and reliable.
Description of drawings
Accompanying drawing is the structural representation of the utility model specific embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described:
As shown in drawings, the cavity 2 outer sleeve pipes 1 that are provided with of the present utility model, loading catalyst in the cavity 2 forms catalytic bed 3, between a plurality of cavitys 2, use header tube 4 and lower collecting box pipe 5 couples together, form air inlet and gas outlet, there is sleeve pipe 1 cavity 2 outsides, and water or other heat carriers are arranged in the sleeve pipe 1, be connected with lower collecting box 7 with upper header 6 between a plurality of sleeve pipes 1, form the outlet of water inlet and steam water interface.Row's number of cavity 2 and sheet number can be determined according to production capacity.
