[0002] The waste gas contains a large amount of smoke and harmful substances and is accompanied by high temperature. In order to achieve the purpose of energy saving, a heat recovery device for waste gas treatment is needed to recover the heat energy of the high-temperature industrial waste gas. Since the waste gas may carry some dust and particulate matter, these dust and particulate matter need to be filtered in advance to reduce damage to the heat exchange equipment. In addition, the heat exchange tubes of the existing heat recovery device are usually fixed in position, which makes the heat exchange efficiency of the liquid low.

[0003] For example, an exhaust gas heat recovery device with announcement number CN213238551U includes a heat exchange box, an air inlet pipe is vertically fixedly connected to the left side of the upper surface of the heat exchange box, the bottom of the air inlet pipe runs through one end of the heat exchange box and is fixedly connected to the heat exchange pipe, the heat exchange pipe is evenly coiled in the heat exchange box, and the other end of the heat exchange pipe is fixedly connected to the air outlet pipe, the bottom of the air outlet pipe runs through the right side of the lower surface of the heat exchange box; an insulation cavity is arranged in the heat exchange box, the insulation cavity is filled with glass rock wool insulation material, and the left and right sides of the bottom of the heat exchange box are respectively fixedly installed The temperature sensor and the water level sensor can exchange the waste heat in the exhaust gas for heating the water in the heat exchange box through the heat exchange tubes in the heat exchange box, thereby making rational use of the waste heat in the exhaust gas. In addition, by providing an insulation chamber in the heat exchange box and glass rock wool insulation materials in the insulation chamber, the insulation effect of the heat exchange box can be improved.
