Problems solved by technology

[0002] At present, in the chemical industry, compared with batch and semi-batch reaction processes, the continuous reaction process has the advantages of high reaction efficiency, easy control of process parameters, and intrinsic safety. However, the heat extraction power of the heat exchange equipment in the continuous reaction process cannot meet production needs. , especially for the strong exothermic reaction process, it is easy to lead to the occurrence of production safety accidents. Therefore, it is necessary to provide a heat exchanger with high heat extraction power and improved intrinsic safety level of the reaction process to meet the above requirements

Embodiment 1

[0050] use as Figure 1-2 In the structure shown, silicon-aluminum alloy (with a silicon content of 15wt%) is used for the substrate and the heat exchange medium channel.

[0051] The heat exchange medium channel 1 and the reaction fluid channel 2 are respectively fixed in the base body 4, and the heat exchange medium channel is composed of 4 straight tubes; the reaction fluid channel is composed of 8 straight tubes, except for the reaction fluid inlet 21 and the reaction fluid outlet 22. The other nozzles are respectively connected to the adjacent reaction fluid channels end to end through the elbow section 3, so that 8 straight pipes form a complete coil tube, and the coil tubes are dispersed and wrapped around the heat exchange medium channels, wherein the adjacent reaction fluid channels The distance between 2 is 4-6 times the diameter of the reaction fluid channel, and the distance between the reaction fluid channel 2 and the adjacent heat exchange medium channel 1 is 2-4...

Abstract

The invention relates to the field of heat exchangers, and discloses a heat exchange unit and a heat exchange reactor. The heat exchange unit comprises a base body (4), and a heat exchange medium channel (1) and reaction fluid channels (2) which are arranged in the base body (4), and is characterized in that the heat exchange medium channel (1) is positioned in a center of the heat exchange unit,the plurality of reaction fluid channels (2) are dispersedly wrapped outside the heat exchange medium channel (1), wherein the heat exchange medium channel (1) is parallel to the axial direction of the reaction fluid channels (2). For a strong exothermic reaction process with high risk, stable process parameter control and passive intrinsic safety level improvement can be realized.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a heat exchange unit and a heat exchange reactor. Background technique [0002] At present, in the chemical industry, compared with batch and semi-batch reaction processes, the continuous reaction process has the advantages of high reaction efficiency, easy control of process parameters, and intrinsic safety. However, the heat extraction power of the heat exchange equipment in the continuous reaction process cannot meet production needs. , especially for a strongly exothermic reaction process, it is easy to lead to production safety accidents. Therefore, it is necessary to provide a heat exchanger with a high heat extraction power and an improved intrinsic safety level of the reaction process to meet the above requirements. Contents of the invention [0003] An object of the present invention is to provide a heat exchanging unit to improve heat exchanging performance and have bet...
