Embodiment Construction

[0027] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through a specific embodiment.

[0028] A preheater with a compensator protection structure disclosed in this embodiment is specifically a plate-type air and gas preheater, such as Figure 1-Figure 5 As shown, it includes a frame 1, a heat exchange unit 2 arranged in the frame 1, and a compensator 3 made of stainless steel that respectively connects the frame 1 and the heat exchange unit 2. The heat exchange unit 2 is usually composed of a plurality of heat exchange fin channels 23 Composition, the sides of a plurality of heat exchange fin channels 23 are connected together through the end plate 24, the heat exchange unit 2 is connected to the frame 1 and the heat exchange unit 2 on the end plate 24, the present invention is different from the existing preheater The advantage is that it also includes a stainless steel protection plate 4 fo...

Abstract

The invention discloses a preheater with protection structures for compensators. The preheater comprises a framework, heat exchange units and the compensators, and further comprises stainless steel protective plates, wherein the heat exchange units are arranged in the framework, the compensators are connected to the framework and the heat exchange units separately, the stainless steel protective plates are used for shielding the compensators to reduce heat transfer and substance contact. The preheater has the advantages that the stainless steel protective plates are arranged so that heat of heat source gas transferred to the compensators can be decreased, corrosive substances in the heat source gas can be prevented from making contact with the compensators through the stainless steel protection plates, and therefore the compensators can be protected, and the service life of the compensators can be prolonged.

Description

technical field [0001] The invention relates to the field of preheaters, in particular to a preheater with a compensator protection structure. Background technique [0002] In metallurgy, electric power and other industries, many hot blast stoves, heating furnaces, combustion furnaces, and boilers produce a large amount of flue gas, and the temperature of the flue gas is relatively high. If the flue gas is discharged directly, a lot of heat will be wasted. In order to recover the flue gas Generally, a preheater is used on the spot to transfer the heat in the flue gas to the air and gas required for the combustion of these furnaces. After the air and gas are preheated, the temperature rises, and the combustion temperature also increases, which can save fuel, reducing production costs. [0003] An existing rectangular interface corrugated compensator dedicated to plate air and gas preheaters has a structure including four sections of straight-sided corrugations and four secti...
