Embodiment Construction

[0034] A jet-type shell-and-tube heat exchanger, such as figure 1 As shown, the shell-and-tube heat exchanger includes a shell 20, a heat exchange component 23, a shell side inlet connection 211 and a shell side outlet connection 221; the shell side inlet connection 211 and the shell side outlet connection 221 are respectively located in the The lower end and the upper end of the heat exchanger; the heat exchange component 23 is arranged in the shell 20, and the heat exchange component is fixedly connected to the upper tube plate 16 and the lower tube plate 19; the shell side inlet connection 211 and the shell side outlet connection 221 are all arranged on the shell 20; the gas enters from the shell-side inlet connecting pipe 211, passes through the heat exchange components for heat exchange, and exits through the shell-side outlet connecting pipe 221.

[0035] Preferably, the heat exchange component extends along the vertical direction. The heat exchangers are arranged verti...

Abstract

The invention provides an air-jet shell-and-tube heat exchanger arranged at intervals up and down. The end of the shell-side inlet pipe is a nozzle structure, and a plurality of horizontal baffles are arranged in the shell, and the baffles extend The entire cross-section of the housing is provided, the wall of the housing is provided with nozzles, and nozzle holes are arranged on the nozzles; the nozzles are provided with a full circle around the vertical inner wall of the housing, and the heat exchange components include The central tube, the left tube, the right tube and the tube group, along the height direction of the central tube, there are multiple tube groups on the same side, and the upper and lower adjacent tube groups are arranged staggered at intervals. In the present invention, intervals are arranged between adjacent annular pipes, and the upper and lower directions are staggered, so that the sprayed fluid can form an S-shaped channel, increase the flow area, prolong the flow path, and fully utilize heat without interruption.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to an air jet shell-and-tube heat exchanger. Background technique [0002] Shell-and-tube heat exchangers are widely used in chemical, petroleum, refrigeration, nuclear energy and power industries. Due to the worldwide energy crisis, in order to reduce energy consumption, the demand for heat exchangers in industrial production is also increasing. The quality requirements for heat exchangers are also getting higher and higher. In recent decades, although compact heat exchangers (plate, plate-fin, press-welded plate heat exchangers, etc.), heat pipe heat exchangers, direct contact heat exchangers, etc. have been developed rapidly, but due to the The heat exchanger has a high degree of reliability and wide adaptability, and it still occupies a dominant position in output and consumption. According to relevant statistics, the current consumption of shell-and-tube heat exchangers in in...
