Problems solved by technology
[0002] In the heat exchangers used in the existing chemical industry, heat dissipation fins or heat dissipation plates are generally fixed on the outer wall of the heat exchange feed pipe for heat dissipation, and the heat exchange feed pipe is used to ensure that the materials flowing inside can exchange heat thoroughly , it needs to bend and coil the heat exchange feed pipe to increase the heat exchange effect, which increases the total length of the heat exchange feed pipe and greatly increases the volume of the heat exchanger

The invention discloses a chemical heat exchanger which comprises a main shell. A plurality of heat exchange plates are fixed in the middle of the main shell, the outer side walls of the heat exchangeplates are fixed on the inner side wall of the main shell, a plurality of heat exchange through holes are formed in the heat exchange plates, a middle conveying pipe is inserted and sleeved in middlethrough holes of all the heat exchange plates, and the outer side wall of middle conveying pipe is welded and fixed on the inner side walls of the middle through holes. A spiral shaft is arranged inthe middle conveying pipe, so that the flow time of heat exchange raw materials can be increased in the middle conveying pipe, the heat exchange effect and efficiency are increased, the length of themiddle conveying pipe does not need to be increased, the size of the heat exchanger is greatly reduced, and the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a chemical heat exchanger. Background technique [0002] In the heat exchangers used in the existing chemical industry, heat dissipation fins or heat dissipation plates are generally fixed on the outer wall of the heat exchange feed pipe for heat dissipation, and the heat exchange feed pipe is used to ensure that the materials flowing inside can exchange heat thoroughly , which requires bending and coiling the heat exchange feed pipe to increase the heat exchange effect, which increases the total length of the heat exchange feed pipe and greatly increases the volume of the heat exchanger. Contents of the invention [0003] The purpose of the present invention is to provide a chemical heat exchanger for the deficiencies of the prior art, which sets a screw shaft inside the middle delivery pipe, so that the heat exchange raw material can increase the flow time in the m...
