The invention discloses a medium polymerization-proof spiral tube heat exchanger for a chemical vacuum system, which comprises a plurality of spiral tube monomers, a medium inlet main pipe, a medium outlet main pipe, a cooling water inlet main pipe and a cooling water outlet main pipe, and the spiral pipe monomers are stacked Together and fixed to each other by fasteners, the spiral tube unit has a medium inlet, a medium outlet, a cooling water inlet and a cooling water outlet. Each medium inlet is connected to the medium inlet main pipe, and each medium outlet is connected to the medium outlet main pipe. Each cooling water inlet is connected to the cooling water inlet main pipe, and each cooling water outlet is connected to the cooling water outlet main pipe. The spiral tube unit includes an upper cover plate, a lower cover plate and a spiral plate. The spiral plate is arranged between the upper cover plate and the lower cover plate. The spiral plate has an arc segment at the central position and the end of the extension. The plate and the lower cover plate construct two areas in the helical tube unit: the medium helical groove and the cooling water helical groove.
Description
technical field [0001] The invention relates to the field of heat exchangers, in particular to a spiral tube heat exchanger used in a chemical vacuum system to prevent medium polymerization. Background technique [0002] A heat exchanger is a commonly used device in a process system, which is used to cool or heat the medium to the required condition for subsequent operation. [0003] In the chemical vacuum system, a cooling heat exchanger is often installed in front of the vacuum system to allow the gas entering the vacuum pump to enter the vacuum pump under relatively low conditions, because the medium of organic matter is more likely to undergo polymerization under high temperature conditions to form flocculent high Molecules, and then stuck vacuum pump. [0004] In the prior art, the heat exchangers under different process conditions have specific heat loads, and the heat exchanger needs to be replaced when the process conditions are changed, which is very troublesome an...
