With the continuous improvement of people's quality of life, the catering service industry has developed rapidly, especially in densely populated streets and residential areas, where there are many restaurants and restaurants in concentrated locations. Therefore, while these restaurants are convenient for people to eat, a large amount of oil fume discharged into the air without treatment in the kitchen has also brought serious pollution to people's living environment. A large number of studies have shown that, Oil fume contains a large amount of alkanes, olefins, fatty acids, and aldehyde compounds and other harmful substances. Long-term inhalation will seriously endanger human health. Oil fume is an aerosol composed of gas, solid, and liquid, which brings certain difficulties to treatment. At present, in In terms of cooking oil fume purification, most of the domestic and foreign dust purification technologies use single purification technologies such as filtration, washing, electrostatic, and centrifugation. Among them, electrostatic purification technology has high purification efficiency and is the most commonly used method. It has a strong coagulation effect, and it is difficult for the purification equipment using a single purification mechanism to remove the captured oil, which often makes it difficult for the purification equipment to operate stably and the purification efficiency is low.

The right end of the purification device is connected with a blower through a ventilation pipe, and a frequency converter is connected below the connection between the ventilation pipe and the purification device. The frequency converter is connected to the additional replenishment device and the circulating water tank in turn. Two waste water recovery tanks are connected to the lower end of the purification device, and the two waste water recovery tanks are connected to cleaning water valves. The waste water recovery tank on the right side is A circulation pipe is connected, and the circulation pipe is connected with a circulation water tank.

As a preferred technical solution of the present invention, the circulation pipe is provided with a water outlet valve.

As a preferred technical solution of the utility model, the bearing and the filter screen are in a vertical structure.

The beneficial effects of the utility model:

The device of the utility model has a simple structure, adopts a compound oil fume purification method combining inertial separation, filtration and wet washing, and improves the purification efficiency. At the same time, the system also has an automatic cleaning function, which not only avoids the removal of deposited oil, but also prolongs the filter material. It is a convenient and effective new oil fume purification device.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Example:

As shown in Figure 1, a new oil fume purification device includes a gas collection hood 1 and an additional supply device 2, the gas collection hood 1 is connected to a purification device 4 through an air intake pipe 3, and a fan is arranged in the purification device 4 Blade 5, filter screen 6, bearing 7 and two shower nozzles 8, described bearing 7 passes fan blade 5 and is connected with filter screen 6, and described bearing 7 and filter screen 6 are vertical structure, two described shower nozzles 8 A water inlet valve 10, a water pump 11 and a circulating water tank 12 are sequentially connected through a water pipe 9, one end of the circulating water tank 12 is connected with a liquid level control device 13 and a water supply valve 14, and the other end is connected with a drain valve 15, and the purification device 4 The right end of the air duct 16 is connected with a blower 17, and the bottom of the connection between the ventilation duct 16 and the purification device 4 is connected with a frequency converter 18, and the frequency converter 18 is connected with the additional supply device 2 and the circulating water tank 12 in turn. The lower end of the purification device 4 is connected with two waste water recovery tanks 19, and the two waste water recovery tanks 19 are connected with a cleaning water valve 20, and the waste water recovery tank 19 on the right side is connected with a circulation pipe 21, and the circulation pipe 21 is provided with a water outlet valve 22, and the circulation pipe 21 is connected to the circulation tank 12; driven by the negative pressure generated by the blower 17, the smoke enters the purification device 4 from the air intake pipe 3, and changes after encountering the rotating fan blade 5. The flow direction rotates with the fan blade 5, and because the oil fume has a certain permeability, the larger and heavier particles will directly adhere to the fan blade 5 or the wall when changing the direction of motion during the inertial collision with the fan blade 5 The soot air flow after passing through the fan blade 5 deviates from the original axial flow direction due to inertia, and makes a circular motion in the tangential direction, which is produced by the mist washing liquid sprayed from the nozzle 8 installed behind the fan blade 5. Cross-collision. During this process, oil fume particles and liquid droplet particles continuously collide, intercept and absorb. The energy of the soot particles reduces the speed of movement, prolongs the time for the particles to stay in this area, and improves the purification effect of inertial separation. The waste water recovery tank 19 at the bottom of the device cleans the collected sewage through the cleaning water valve 20 and then discharges the device. The clean liquid that does not flow into the waste water recovery tank 19 flows into the circulating water tank 12 for recycling.

Based on the above, the device of the utility model has a simple structure, and adopts a compound oil fume purification method combining inertial separation, filtration and wet washing, which improves the purification efficiency. It is a convenient and effective new type of oil fume purification device that shortens the use time of the filter material.
