Abstract

The invention relates to the technical field of heat exchange equipment, in particular to a double-tube-plate heat exchanger. The double-tube-plate heat exchanger comprises a shell. A plurality of heat exchange pipes are arranged in the shell and axially parallel to one other. The two ends of the shell are each provided with an end socket. A first tube plate and a second tube plate are sequentially arranged between the shell and one of the end sockets. The shell is fixedly connected with the first tube plate. One of the end sockets is fixedly connected with the second tube plate. A preset interval is set between the first tube plate and the second tube plate. A plurality of adapting pipes are connected between the first tube plate and the second tube plate. The number of the heat exchange pipes is equal to that of the adapting pipes. The ends of the heat exchange pipes are arranged in the first tube plate, the second tube plate and the adapting pipes in a penetrating mode. According to the double-tube-plate heat exchanger, the seal safety performance of the heat exchanger is improved; seal leakage of the first tube plate and / or seal leakage of the second tube plate can be discovered timely, so that the double-tube-plate heat exchanger is convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a double-tube-sheet heat exchanger. Background technique [0002] As heat exchange equipment, heat exchangers are widely used in heat recovery and anti-corrosion fields in industry. The traditional single tube sheet 101 sealing method: see figure 1 and figure 2 As shown, the single tube sheet 101 is pressed between the shell flange 102 and the tube sheet flange 103 by fasteners; the inside of the shell 104 and the outside of the heat exchange tube 105 are the service side 108, the inside of the head 106 and the The inner side of the heat exchange tube 105 is called the process side 107 , and the inner side of the head 106 communicates with the inner side of the heat exchange tube 105 . The heat exchange tube 105 is inserted into the single tube plate 101, the O-ring 110 and the gasket 111 between the heat exchange tube 105 and the single tube plate 101 act as a...
