Abstract
The utility model designs a radial fixed bed catalytic reactor for co-producing steam. A group of water-cooled pipes is arranged in the radial reactor, high-temperature reaction heat generated by reaction is used for heating cooling water so that the cooling water can be vaporized for co-producing the steam, and the purpose of recovering energy is achieved. The reactor has the advantages of little resistance of a bed layer, high space speed, large production capacity and reasonable energy utilization, and the utility model is a more promising fixed bed catalytic reactor. The utility model can be widely used for ammonia synthesis, methanol synthesis, the process of carbon monoxide conversion, the hydrogenation process of organic compounds and the process of other strong exothermic reactions.
Description
The utility model relates to a kind of fixed bed catalytic reactor.
Fixed bed catalytic reactor is a kind of reactor commonly used in chemical industry and the petrochemical industry, is widely used in the hydrogenation process of synthetic, the carbon monodixe conversion process of synthetic, the methyl alcohol of ammonia, organic compound and other reversible exothermic reaction processes.For this reason, many scientific workers have designed numerous various types of fixed bed catalytic reactors, at present, the reactor of industrial use can be divided into two classes from liquid form: Radial Flow and axial flow also can be divided into two classes from heat exchange in form: external-cooling type and self-cooled.Deutsche Bundespatent (DE2123950) and Japan Patent (J63123433) disclose a kind of synthetic tower of axial flow byproduct steam respectively, this synthetic tower energy byproduct steam, the energy utilization is comparatively reasonable, but bed resistance is big, be difficult to improve air speed, production capacity is not high, Danish Patent (WO9009234) discloses a kind of radially synthetic tower, such synthetic tower, overcome the big shortcoming of axial flow reactor beds layer resistance, production capacity increases substantially, but fails rationally to recover energy, can not byproduct steam, cause effective loss of energy.For this reason, a kind of new fixed bed reactors of people's phase developmental research are to satisfy industrial needs.
The purpose of this utility model is to overcome the shortcoming of above-mentioned two kinds of fixed bed catalytic reactors, and the advantage of comprehensive two kinds of reactors designs a kind of radially byproduct steam fixed bed catalytic reactor, and it is big to reach production capacity, rationally utilizes energy, the purpose of byproduct steam.
Design of the present invention is such:
Usually, fixed bed catalytic reactor by the urceolus that bears high pressure and only bear pressure reduction internals---basket is constituted.The utility model is provided with one group of water cooling tube in the basket of radial fixed-bed reactor, the high-temperature reaction heat that is produced when the reacting gas radial flow is crossed bed is by the water cooling in the water cooling tube, and water heating back vaporization produces steam, reclaim high-temperature reaction heat, reach the purpose of rationally utilizing energy.Said reactor combines the advantage of radial reactor and axial byproduct steam reactor, will be a kind of very promising fixed bed catalytic reactor.
According to above-mentioned design, the utility model has designed a kind of radially byproduct steam fixed bed catalytic reactor, further sets forth architectural feature of the present utility model below in conjunction with accompanying drawing.
