The heat exchange assembly 2 includes a spiral heat-conducting plate 204 installed inside the water storage tank 101. A heat-conducting pipe 203 is installed inside the spiral heat-conducting plate 204, and a connecting pipe 201 is installed on the side of the heat-conducting pipe 203. A spiral groove 202 is opened on the connecting pipe 201. The inner side of the spiral groove 202 is fixedly connected to the spiral heat-conducting plate 204, and the side of the spiral heat-conducting plate 204 is fixedly connected to the water storage tank 101. A liquid channel 205 is formed between the water storage tank 101, the connecting pipe 201, and the spiral heat-conducting plate 204. A flue gas inlet pipe 3 is installed at one end of the connecting pipe 201, and a separation assembly 4 is installed at the other end of the connecting pipe 201. The spiral heat-conducting plate 204 and the heat-conducting pipe 203 can quickly remove heat from the flue gas, allowing the heat of the flue gas to exchange with the water in the liquid channel 205, thereby improving the efficiency of heat exchange. The separation assembly 4 includes a separation box 401. A fixing pipe 403 is installed on one side of the separation box 401, and one end of the fixing pipe 403 is fixedly connected to the connecting pipe 201. An exhaust pipe 404 is installed on the other side of the separation box 401. A box cover 406 is rotatably fitted on the top of the separation assembly 4. A fixing hole 407 is opened on the top of the box cover 406. A cleaning assembly 6 is installed inside the fixing hole 407. Sliding grooves 402 are opened on both sides of the inner wall of the separation box 401. The filter assembly 5 is slidably fitted in the sliding grooves 402. An oil guide groove 405 is opened at the bottom of the inner cavity of the separation box 401. An oil guide pipe 408 is installed at the bottom of the oil guide groove 405. The bottom end of the oil guide pipe 408 is connected to the oil storage tank 7. The filter assembly 5 is limited by the sliding grooves 402 and the box cover 406, which facilitates the disassembly, assembly and maintenance of the filter assembly 5 by the staff, greatly improving work efficiency.The filter assembly 5 includes a fixed frame 501 that slides within the slide groove 402. A filter plate 502 is installed on the inner side of the fixed frame 501. A placement groove 503 is provided on the top of the fixed frame 501. A handle 504 is rotatably fitted in the placement groove 503. The filter plate 502 cooperates with the cleaning assembly 6. The filter plate 502 is an oil fume separation filter plate. The cleaning component 6 includes a fixed cylinder 601 installed inside the fixed hole 407. A pull rod 603 is slidably fitted inside the fixed cylinder 601. A cross-shaped groove 602 is opened on the inner side of the fixed cylinder 601. A limiting plate 604 is slidably fitted inside the cross-shaped groove 602. The pull rod 603 is fixedly connected to the limiting plate 604. A pull plate 605 is installed on the top of the pull rod 603. A scraper 606 is installed on the bottom of the pull rod 603. The scraper 606 cooperates with the filter plate 502. The scraper 606 is triangular, which facilitates the upward scraping of oil. During this process, the waste oil is guided by the inclined surface into the oil guide groove 405.

[0041] Implementation process: During use, room temperature water is injected into the liquid channel 205 through the water inlet pipe 102 and the water inlet valve 103. Oil fumes enter the connecting pipe 201 through the smoke inlet pipe 3. The heat from the oil fumes diffuses through the heat-conducting pipe 203 and the spiral heat-conducting plate 204. Because the water flows within the liquid channel 205, the contact area between the water and the spiral heat-conducting plate 204 is increased, thereby improving heat dissipation efficiency. The heat is absorbed by the water flowing within the liquid channel 205, achieving the goal of heating the water source for later use, greatly improving the utilization rate of thermal energy, saving energy and protecting the environment. Then, the oil fumes enter the separation box 401 through the connecting pipe 201 and the box cover 406. The waste oil is filtered through two filter plates 502 in sequence, thus separating it from the exhaust gas and purifying the flue gas. Then, by reciprocatingly pulling the pull plate 605, the pull plate 605 drives the scraper 606 to move back and forth via the pull rod 603. During the movement, the scraper 606 scrapes off the waste oil on the filter plates 502, allowing the waste oil to be guided into the oil storage tank 7 through the oil guide groove 405 and the oil guide pipe 408. This allows the workers to perform secondary treatment of the waste oil for the production of biodiesel or other industrial uses. This not only recovers heat energy but also realizes the resource utilization of waste oil, improving overall economic efficiency.

[0042] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
