Problems solved by technology

[0002] The heat exchanger realizes the heat exchange between the medium in the tube side and the shell side through the heat exchange tube. Most of the heat exchangers currently used are equipped with straight tube heat medium tube bundles. This kind of heat exchanger mainly has the following disadvantages: heat medium The tube bundle is limited by the tube length, so the length of the heat medium tube bundle is small, and the medium flows evenly in the straight tube, which makes the turbulence effect of the heat exchanger poor, resulting in insignificant heat transfer effect, which is not conducive to improving heat transfer efficiency
Most of the above-mentioned heat exchangers are floating head heat exchangers. The floating head needs to be disassembled for tube bundle cleaning, which is inconvenient to clean, and there will be a certain force between the tube plate and the cylinder at the floating head end, which is not conducive to the long-term stable heat exchange operation of the heat exchanger.

Abstract

The invention discloses a chloromethane copious cooling floating head type heat exchanger, which comprises a shell, a supporting seat, a sealing head and an outer head cover. The shell is internally provided with tube bundles. The sealing head is connected with the shell through a first set of flanges. A fixing pipe plate is arranged between the first set of flanges. The fixing pipe plate is in mortise-tenon connection with a first flange. The contact surfaces of two end faces of the fixing pipe plate and the first set of flanges are correspondingly provided with first sealing rings. The shellis connected with the outer head cover through a second set of flanges. The second set of flanges is internally provided with second sealing rings. The outer head cover is internally provided with afloating head cover. A floating head pipe plate is arranged at the end, near the shell, of the floating head cover through hook rings. Two ends of each tube bundle are correspondingly fixed to the fixing pipe plate and the floating head pipe plate. A first liquid outlet and a liquid inlet are formed in the upper end and the lower end of the sealing head correspondingly. An air inlet, an air outletand a second liquid outlet are formed in the shell. A drainage opening and an emptying opening are formed in the upper end and the lower end of the outer head cover correspondingly. The chloromethanecopious cooling floating head type heat exchanger has simple structure and good sealing property.
