Heat exchanger with waste heat recovery structure

The invention relates to the technical field of heat exchanger production, in particular to a heat exchanger with a waste heat recovery structure, which comprises a heat exchanger body, the top surface of the heat exchanger body is fixedly connected with a filtering mechanism, the filtering mechanism comprises a rectangular shell, and one end of the interior of the rectangular shell is provided with a cleaning assembly. And an extrusion assembly is arranged at the other end of the interior of the rectangular shell. According to the device disclosed by the invention, particulate matters adsorbed on a filter plate can be scraped off by a brush through rotation of two reciprocating screw rods I, and then the particulate matters falling into a clip-shaped frame II at a corresponding position can be collected in a centralized manner through intermittent opening and closing of two groups of sealing plates, so that the filter plate does not need to be manually cleaned; and flue gas can be continuously injected into
