▎ 摘　　要

NOVELTY - The device has waste heat recycling unit and an oil smoke filter unit. The waste heat recovery unit includes a box structure (6) that is provided with a heat exchange core. The heat exchange core includes a front tube plate (5) that is arranged on the front side of the box structure. The rear tube plate (10) is provided on the rear side of the box structure. The front tube plate is provided with a flow deflector (3), and the front and rear sides of the box structure are respectively provided with a front end cover (2) and a rear end cover (12). The front end cover is provided with a fresh air inlet, and the rear end cover is provided with an air outlet (14). The upper portion of the box is provided with an exhaust gas outlet pipe (9) for connecting the exhaust fan, and the lower portion is provided with an exhaust gas inlet pipe. The lower end of the exhaust gas inlet pipe (16) is connected with the oil fume filter unit. USE - Graphene corrugated pipe waste heat oil smoke filtering device for recycling device used in domestic smoking furnace. ADVANTAGE - The fin-shaped graphene circular tube afterheat recycling device with high heat exchange efficiency, convenient disassembly, small pollution and easy cleaning is provided. The connection between the back tube plate of the front tube plate and the box body is easy to disassemble and convenient to clean. The oil smoke filtering unit makes the waste gas pure degree lifting and prevents the oil smoke particulate matter being attached to the corrugated pipe to affect the heat transfer efficiency.
