Problems solved by technology

In such a cycle, the heat is transferred from one end of the heat pipe to the other end. Due to the existence of an intermediate medium, there is heat loss, and its heat transfer efficiency is generally lower than that of a plate preheater.

Embodiment Construction

[0019] The countercurrent heat flow corrugated plate for gas-gas preheater of the present invention will be further described in detail with reference to the accompanying drawings. It should be understood that the following examples are only used to illustrate the present invention but not to limit the scope of the present invention.

[0020] Such as figure 1 and image 3 As shown, the countercurrent heat transfer corrugated sheet used in the gas-gas preheater of the present invention has a hexagonal shape as a whole, and is composed of a diversion area 10 and a heat transfer area 20, wherein the heat transfer area 20 is located in the counter flow area. In the middle of the heat corrugated sheet, the flow guide area 10 is arranged at both ends of the heat transfer area 20 .

[0021] The heat transfer area 20 is evenly distributed with concave and convex corrugations 21 and 22 arranged at intervals, and the form of the concave and convex corrugations 21 and 22 can be circula...

Abstract

The invention discloses a countercurrent heat-transfer corrugated plate sheet for a gas-gas pre-heater. The countercurrent heat-transfer corrugated plate sheet is wholly of a hexagon shape and is composed of heat conducting areas and a heat transfer area, wherein the heat transfer area is located in the middle of the countercurrent heat-transfer corrugated plate sheet and the heat conducting areas are arranged at the two ends of the heat transfer area. The countercurrent heat-transfer corrugated plate sheet provided by the invention has the advantages of high heat transfer efficiency, high temperature resistance, small fluid resistance, difficulty in scaling, zero dead zone, convenience in cleaning, simple mould manufacturing, and the like, and can be used as a heat transfer element for a whole welding plate type gas-gas pre-heater.

Description

technical field [0001] This invention relates to a general part of preheating and heat transfer equipment, and in particular to a countercurrent heat transfer corrugated plate for a gas-to-gas preheater. Background technique [0002] Fully welded counterflow plate gas-gas preheater is used in various industries. Pure counterflow plates can further increase the logarithmic average temperature difference, reduce the overall equipment footprint, reduce equipment weight, and significantly improve heat exchange efficiency. The countercurrent corrugated plate as its heat transfer element directly affects the heat transfer effect of the preheater. [0003] A typical heat pipe is composed of a tube shell, a liquid-absorbing core and an end cap. After the tube is pumped into a negative pressure, it is filled with an appropriate amount of working liquid, so that the capillary porous material of the liquid-absorbing core close to the inner wall of the tube is filled with liquid and the...
