Embodiment Construction

[0033] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] In this article, if there is no special explanation, when it comes to formulas, " / " means division, and "×" and "*" mean multiplication.

[0035] figure 1 A shell-and-tube heat exchanger for uniform outlet gas temperature is disclosed. like figure 1 As shown, the heat exchanger includes an upper header 8, a lower header 9, and a heat exchange tube 1 arranged between the upper and lower headers; the heat exchanger includes a gas inlet 6 and a gas outlet 7, and the gas flows from the gas inlet 6 flows in, exchanges heat with the fluid in the heat exchange tube 1 in the heat exchanger, and then flows out from the gas outlet 7.

[0036] As an improvement, the gas outlet 7 is connected to the outlet pipe 5, such as figure 2 As shown, the outlet pipe 5 is provided with a baffle 2 extending from the inner wall 51 of the outlet pipe to...

Abstract

The invention provides a shell-and-tube heat exchanger with optimized structures. Drainage plates extending from the inner wall of an outlet pipe to the center of the outlet pipe are arranged in the outlet pipe, the drainage plates comprise first linear walls and second linear walls which extend from the inner wall, the acute angles between the second linear walls and the inner wall are A1, in a gas flow direction, the multiple drainage plates are arranged on the inner wall of the outlet pipe, and the included angles A1 become larger and larger in the gas flow direction. According to the novel shell-and-tube heat exchanger provided by the invention, the included angles are set to be larger and larger so that the size can be reduced, the flow resistance can be reduced, and a temperature equalizing effect can be basically the same on the aspects of resistance reduction and material cost saving.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a shell-and-tube heat exchanger in which gas participates in heat exchange. 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 he...
