Through the first baffle 19, the contact time between the flue gas and the water is prolonged, and the flue gas and the water are further fully contacted. The second baffle 20 blocks the bubbles generated by the exhaust hood 18 through the second baffle 20 to prevent the bubbles from floating too slowly. The right side of the second baffle 20 is located between the center positions of the front and rear sides of the inner cavity of the casing 1 Two third baffles 22 are arranged successively along the left and right directions, and the oil on the water surface is blocked by the third baffles 22. The first rotating rod 23 is connected through the bearing, and the left and right ends of the outer wall of the first rotating rod 23 and the center position of the outer wall are all interference-fitted with the inner ring of the bearing. The outer rings of bearings are fixedly connected to the top ends of the sides, and the bottom ends of the left front side of the two third baffle plates 22 and the second baffle plate 20 are connected with the second rotating rod 24 through bearings along the left and right directions, and the second rotating rod 24 The left and right ends of the outer wall and the center of the outer wall are all interference-fitted with the inner ring of the bearing. The two third baffles 22 and the bottom of the left front side of the second baffle 20 are fixedly connected with the outer ring of the bearing. Between the baffle plates 22 and between the second baffle plate 20 and the third baffle plate 22, on the outer walls of the first rotating rod 23 and the second rotating rod 24 Conveyor belts 21 are installed, between the two third baffles 22 and between the second baffle 20 and the third baffle 22 are located on the rear side of the casing 1 along the left and right directions are provided with an oil discharge bucket 25, and the discharge The oil bucket 25 is located at the bottom of the first rotating rod 23 and extends out of the rear side of the outer wall of the casing 1. The oil is scraped off the conveyor belt 21 through the top of the oil discharge bucket 25, and the oil is discharged through the inner cavity of the oil discharge bucket 25. Exhaust, the left side of the outer wall of the first rotating rod 23 extends out of the left side of the second baffle plate 20 and is keyed to the first bevel gear 16, the left side of the first bevel gear 16 is located at the top of the inner cavity of the casing 1 and passes through The pin shaft is connected with a second bevel gear 26, and the first bevel gear 16 is engaged with the second bevel gear 26.

[0020] As a preferred solution, further, the outer rings of the two fans 13 are provided with anti-fouling covers, and the anti-pollution covers prevent oil pollution from invading the inside of the fans and causing damage.
[0021] As a preferred solution, further, the height of the oil discharge hopper 25 is higher than the top front side of the second baffle 20 to prevent water from entering the oil discharge hopper 25 .
[0022] As a preferred solution, further, the height of the second baffle plate 20 is the same as that of the drain pipe 5 , so as to prevent the water level from being too high and causing water to flow into the oil drain hopper 25 .
[0023] As a preferred solution, further, the heights of the two third baffles 22 are both higher than the second baffle 20, so that the third baffles 22 can block the oil on the water surface.
[0024] Its detailed connection means is a well-known technology in the art. The following mainly introduces the working principle and process, and the specific work is as follows.
[0025]During use, connect the external power supply of motor 6 and blower fan 13, connect the external water pipe of water inlet pipe 4 and drain pipe 5, pour water in the casing 3 by water inlet pipe 4, when the water level in the casing 3 is the same as that of the drain pipe 5 After the position is level, the drain pipe 5 discharges the water to keep the water level unchanged. The fan 13 sucks the oily fume into the fume collecting hood 1. The oily fume first passes through the dust collection net 12, and the dust collection net 12 filters the large particles of oil fume, and the oil fume passes through the fan. It is sent into the air inlet duct 2, and then enters the casing 3 through the air inlet duct 2, and the flue gas is evenly discharged in the form of small bubbles through the exhaust hood 18, so that it contacts with water evenly, and the oil in the flue gas is filtered out. The density of oil is lower than that of water, and the oil will float on the surface of the water, and the oil will be blocked on the left side of the third baffle 22 through the third baffle 22, and the water will pass through the bottom of the third baffle 22, and the filtered flue gas Pass above the third baffle plate 22, enter the filter housing 7, filter through the filter element 17, enter the exhaust duct 8, and finally discharge through the exhaust hood 9, and at the same time, the motor 6 drives the fourth bevel gear 10 to drive the third cone. The bevel gear 11 rotates, the third bevel gear 11 drives the second bevel gear 26 to drive the first bevel gear 16 to rotate, the first bevel gear 16 drives the first rotating rod 23 to drive the conveyor belt 21 to rotate, and the conveyor belt 21 drives The second rotary rod 24 rotates, and the conveyor belt 21 drives the oil blocked by the second baffle plate 22 on the water surface backwards, and the oil is scraped off through the contact surface between the top of the oil discharge bucket 25 and the bottom end of the conveyor belt 21, so as to continuously flow into the oil discharge In the bucket 25, the oil is discharged from the casing 1 through the oil discharge bucket 25, so that the oil and water are separated, and other harmful substances in the flue gas are adsorbed by the filter element 17 composed of activated carbon. This device is easy to maintain, simple in structure, easy to operate, and the treatment effect Durable, practical, and conducive to promotion.
