Problems solved by technology

[0004] The purpose of the embodiment of the present application is to provide an air preheating device, which can prevent impurities such as dust from accumulating on the corrugated sealing sheet, thereby improving the heat absorption performance of the corrugated sealing sheet, and solving the problem of removing dust on the corrugated sealing sheet by the air preheating device. When there are impurities, it is necessary to shut down the air preheating equipment, which is not conducive to the continuous operation of the air preheating equipment

Abstract

The invention discloses air preheating equipment, and belongs to the technical field of heat energy recovery. The air preheating equipment comprises a driving mechanism and a preheating mechanism. The preheating mechanism comprises a supporting frame (100) and a corrugated sealing piece (200), the supporting frame (100) is connected with the driving mechanism, the supporting frame (100) is provided with containing space (101), the corrugated sealing piece (200) is movably arranged in the containing space (101), and under the condition that the driving mechanism drives the supporting frame (100) to rotate, the corrugated sealing piece (200) moves in the containing space (101) in a reciprocating manner. By means of the mode, the heat absorption performance of the corrugated sealing piece can be improved, the air preheating equipment does not need to be shut down when dust and other impurities on the corrugated sealing piece are removed, and therefore continuous running of the air preheating equipment is facilitated.

Description

technical field [0001] The application belongs to the technical field of heat energy recovery, and in particular relates to an air preheating device. Background technique [0002] In order to improve the heat exchange performance of the boiler and reduce energy consumption, the air preheating equipment will preheat the air that is about to enter the boiler. [0003] Air preheating equipment is generally divided into three types: plate type, tube type and rotary type. Among them, the rotary air preheating equipment drives the preheating mechanism to rotate through the driving mechanism. When the preheating mechanism rotates to the exhaust port of the boiler, the corrugated sealing sheet arranged on the preheating mechanism absorbs the heat in the exhausted flue gas. When the preheating mechanism rotates to the inlet of the boiler, it transfers the absorbed heat to the air that is about to enter the boiler, thereby increasing the temperature of the air and improving the heat ...
