Reactor

Abstract

The invention relates to a reactor. The reactor comprises an external cylinder, a radial frame and a heat-exchange structure, the radial frame is arranged in the external cylinder, the radial frame comprises a reaction area, the heat-exchange structure comprises several heat exchange tubes, several heat exchange tubes are arranged in an array mode by taking central axis of the radial frame from inside to outside, the transverse section of the heat exchange tube is in an ellipse shape, the central axis of each heat exchange tube and the central axis of the radial frame are coplaned on a first plane, the vertical cross section of a long shaft through the transverse section of each heat exchange tube is a second plane; wherein, the first plane corresponding to the same heat exchange tube and the second plane are arranged with an included angle. During the reaction process, under guiding effect of two ellipsoids of the heat exchange tube along the long shaft direction, the air flow flowed from the peripheral part of the radial frame to the central axis of the radial frame and the radial direction ( a line direction between the central axis of the heat exchange tube and the central axis of the radial frame) are formed with the certain angle. a flow path of the air flow is prolonged, the stay time of the air flow is increased, heat exchange effect is better, and the industrial production requirement is satisfied.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a reactor applied to CO conversion. Background technique [0002] Coal gas, natural gas conversion gas, coke oven gas conversion gas, calcium carbide furnace tail gas, blast furnace gas, etc., all of these gases contain a large amount of CO, for example, calcium carbide tail gas contains 80% CO, and the CO content in coal gas is 30% to 68%. Generally, CO can be changed to useful H 2 , the specific reaction formula is: [0003] CO+H 2 O (steam) = CO 2 +H 2 +Q; [0004] This change reaction is an exothermic reversible reaction, and there must be a catalyst and an excess of H 2 Excess O according to the reaction formula can make the reaction to generate H 2 direction. The activity of the catalyst in this reaction has a certain temperature range. Below a certain temperature, the reaction speed is very slow, and the amount of catalyst needs to be increased. However, ...
