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 a jetting pipe shell type heat exchanger adopting vertical spaced and staggered distribution. A spraying head structure is arranged on the end portion of a shell pass inlet connecting pipe. Multiple horizontal baffles are arranged in a shell. The baffles extend the overall cross section of the shell. Spraying pipes are arranged on the wall face of the shell. Spraying holes are formed in the spraying pipes. A whole circle of spraying pipes are arranged around the vertical inner wall of the shell. A heat exchange part comprises a center pipe, a left side pipe, a right sidepipe and pipe sets. Multiple pipe sets are arranged on the same side in the height direction of the center pipe. The pipe sets adjacent vertically are arranged in a staggered manner at intervals. According to the heat exchanger, adjacent ring-shaped pipes are arranged and distributed in a staggered manner in the vertical direction at intervals, thus sprayed fluid can form an S-shaped channel, thecirculation area is increased, a flowing path is lengthened, and heat can be utilized fully and continuously.

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...
