In a barrel body of the reactor, one side is provided with a diverging device, the other side is provided with a converging device, reacting gas is made to make transverse flow in a bed layer, and the flow path of the lateral flow is a diameter of the reactor; therefore, various advantages of a catalytic reactor with a radial by-product steam fixed bed are kept, the requirement for gaseous uniform distribution is reduced, and the reactor with stronger adaptability can satisfy production requirement under different occasions. The utility model can be used for ammonia synthesis, methanol synthesis, the process of carbon monoxide conversion and the process of reversible exothermic reactions.
Description
The utility model relates to a kind of fixed bed catalytic reactor.
Fixed bed catalytic reactor is a kind of equipment common in the chemical industry, in synthetic, the carbon monodixe conversion of synthetic, the methyl alcohol of ammonia and hydrogenation reaction of organic compounds process use widely.At present, the fixed bed catalytic reactor of industrial use is of a great variety, and common have an axial cooling pipe type, this class reactor beds layer resistance is big, single tower production capacity is not high, and energy can not reclaim effectively, and China all adopts most of small fertilizer plant such ammonia convertor to carry out the synthetic of ammonia; Another kind is the radial flow dynamic formula, and Danish Patent (W09009234) discloses this DESIGN OF REACTOR scheme, and this reactor has lower resistance, the advantage of high-speed, but energy still fails to reclaim; Chinese patent: application number (97234399.7) discloses a kind of radially byproduct steam fixed bed catalytic reactor, this reactor has significant advantage: bed resistance is little, can adopt the granule catalyst, single tower production capacity is big, and can reclaim high-temperature reaction heat, byproduct steam, it is comparatively reasonable that energy reclaims.But this reactor is because gas is Radial Flow, its flow process is the radius of reactor, flow process is short, therefore quite high for the uniform requirement of gas, gas is bias current or short circuit easily in bed, so that can not reach and adopt catalyst particle to improve the purpose of macroreaction speed, especially less for tower diameter, as the reactor of diameter less than 0.5 meter, the course of reaction that gas flow is lower, situation is just more outstanding, for this reason, is necessary to research and develop the stronger fixed bed catalytic reactor of a kind of adaptability.
The purpose of this utility model is to design a kind of horizontal byproduct steam fixed bed catalytic reactor, makes reactor except the every advantage with Radial Flow reactor, also has bigger adaptability, satisfies industrial needs under the different occasions.
Design of the present utility model is such:
In the cylindrical shell of reactor, one side is provided with a flow distribution plate with tap hole, and opposite side is provided with a converging device, the reactor middle part is one group of water cooling tube, in order to recovery heat byproduct steam, and space segment filling catalyst, reacting gas flows into catalyst bed by flow distribution plate after entering reactor, Radial Flow in catalyst bed, by the converging device outflow reactor of opposite side, the flow process of gas is the diameter of reactor then.Therefore the reactor of this structure, gas flow process can adopt granule catalyst and high-speed production much smaller than axial flow reactor, and want specific diameter to be twice to the flow process of reactor, therefore gas is easy to uniformly, is particularly useful for the course of reaction under the low discharge of trourelle footpath, and adaptability is stronger.
According to above-mentioned design, the utility model has designed a kind of horizontal byproduct steam fixed bed catalytic reactor, whole reactor mainly is made up of cylindrical shell, part flow arrangement, converging device and water cooling tube, further specifies architectural feature of the present utility model below in conjunction with accompanying drawing.
