The heat exchange efficiency is further improved.

[0025] The working principle of the oil fume heat recovery heat pipe mechanism is as follows: when the heat recovery work of the oil fume is carried out, the high-temperature oil fume enters the inside of the shell 1 from the smoke inlet pipe 3, and then escapes from the smoke outlet pipe 2; the cold water enters the inside of the heat exchange box 41 from the water inlet pipe 422, and then flows out from the water outlet pipe 423; in this process, when the oil fume contacts the heat exchange box 41 and the fin 432, the high-temperature oil fume will conduct the temperature to the heat exchange box 41 and the fin 432, so as to heat the water flow in the inside of the heat exchange box 41, and make the water flowing out of the water outlet pipe 423 hot; at this time, the interval distribution of the baffle 431 and the fin 432 makes the escape path of the oil fume longer, so as to slow down the passing speed of the oil fume to the maximum extent; similarly, the staggered distribution of the water blocking plate 421 also makes the flow path of the water flow longer, and increases the residence time of the water flow in the inside of the heat exchange box 41, so as to improve the heat exchange efficiency of the two; after the heat exchange, the oil fume will be attached to the surface of the baffle 431, the fin 432 and the heat exchange box 41; at this time, the single-chip microcomputer 6 controls the motor 443 to run, and the output shaft of the motor 443 drives the screw rod 441 to rotate; because the outer surface of the screw rod 441 is in threaded connection with the inside of the mounting frame 442, with the rotation of the screw rod 441, the mounting frame 442 will displace, and the scraper 433 will also move synchronously; with the movement of the scraper 433, the scraper 433 will scrape off the oil fume attached to the surface of the baffle 431, the fin 432 and the heat exchange box 41 along the way; the single-chip microcomputer 6 controls the motor 443 to reverse the scraper 433 to move back and forth in the inside of the shell 1, so as to scrape off all the oil fume attached to the surface of the baffle 431, the fin 432 and the heat exchange box 41, and then accumulate on the left and right sides of the shell 1; after a long period of time, only the two side plates 45 need to be opened, and then the accumulated oil fume can be quickly removed, without the need of dismounting the heat exchange device, which is very convenient.

[0026] It is worth noting that the single-chip microcomputer 6 disclosed in the above embodiment is an S7-200 single-chip microcomputer, and the motor 443 is a PLF motor; the single-chip microcomputer 6 controls the motor 443 to work by using the method commonly used in the prior art.
