Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides an oil fume purification unit, including a main body 11, a control system 12, an operating component 13, a mechanical cyclone separator 14, a liquid film generator 15, a differential oil fume separator 16, and a UV photolysis purification and deodorizing device 17.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, the main body 11 includes a first substrate 111 and a second substrate 112. Both the first substrate 111 and the second substrate 112 are hollow. The first substrate 111 is located above the second substrate 112 and is connected to the second substrate 112. A control system 12 is fixed on the first substrate 111, and an operating component 13 is fixed on the second substrate 112. A smoke outlet passage 113 is opened on the side wall of the first substrate 111, and a smoke inlet passage 114 is opened on the bottom wall of the second substrate 112. The control system 12 is electrically connected to the operating component 13, and the control system 12 is electrically connected to the liquid film generator 15, the differential oil fume separator 16, and the UV photolysis purification and deodorizing device 17.

[0033] like Figure 1, Figure 3 As shown, a waterproof guide plate 115 is fixed inside the second substrate 112 between the smoke inlet passage 114 and the mechanical cyclone separator 14. The output end of the waterproof guide plate 115 is connected to the circulating water tank 152 of the liquid film generator 15.

[0034] like Figure 1 , Figure 3 , Figure 5 As shown, the mechanical cyclone separator 14 is fixed inside the second base 112. The mechanical cyclone separator 14 is a rectangular plate with multiple cyclone centrifugal air slots 141 running through it. The output end of the mechanical cyclone separator 14 is connected to the circulating water tank 152 of the liquid film generator 15. It uses the centrifugal force generated to perform the first stage of separation and purification of oil fumes. It can intercept larger particulate impurities and oil fumes, achieve oil fume separation, filter oil particles with a particle size of 3-10 μm, and achieve a removal rate of 90% for larger particulate oil fumes.

[0035] like Figure 1 , Figure 3 , Figure 6 As shown, the liquid film generator 15 includes a water pump 151, a circulating water tank 152, and nozzles 153. The liquid film generator 15 is fixed inside the second substrate 112. The circulating water tank 152 is fixed at the input end of the water pump 151, and multiple nozzles 153 are fixed at the output end of the water pump 151. The multiple nozzles 153 form a uniformly distributed liquid film layer above the mechanical cyclone separator 14 for second-stage separation and purification. An oil fume purifying agent is added to the liquid film to separate and absorb small and medium-sized particulate impurities and oil fumes, and to cool the oil fumes. The filtered oil particles have a particle size of 0.01um to 10um, with a small and medium-sized oil particle removal rate of 90% and an odor removal rate of 70%.

[0036] like Figure 3 , Figure 4 As shown, the differential oil fume separator 16 has multiple components fixed along the X-axis within the first base 111. The first base 111 and the second base 112 are connected between the mechanical cyclone separator 14 and the differential oil fume separator 16. The differential oil fume separator 16 adopts a double-layer oil fume separation disc with two layers and a differential structure. The oil fume separation disc is driven by a motor to rotate at a speed of 1420 revolutions per minute. The differential oil fume separator 16 is a prior art technology, forming an airflow wall to intercept oil fumes. Then, through the centrifugal force generated by the high-speed rotation, the oil is thrown out and recovered by the mechanical cyclone separator 14. The high-speed rotating fan blades form a physical shield, effectively intercepting oil vapor particles, water vapor particles, fibrous materials, and colloidal substances. The gas can pass freely for third-stage separation and purification, achieving oil and gas separation and purification. The filtered oil and water particles have a particle size of 1μm or larger, and the oil and water particle removal rate reaches 93.7%.

[0037] like Figure 4 As shown, the UV photolysis purification and deodorizing device 17 is fixed inside the first substrate 111. The UV photolysis purification and deodorizing device 17 is a prior art technology. The photolysis technology of the UV photolysis purification and deodorizing device 17 is used as the fourth stage of purification and deodorization. The flue gas that has been separated by the first three stages of purification enters the UV photolysis purification and deodorizing device 17 for the fourth stage of purification. After the UV lamp tube 171 is turned on, it can generate a large number of ultraviolet light beams to irradiate the odor gas, degrade and transform the odor gas into low molecular weight compounds, such as CO2, H2O and other harmless gases, to achieve an effective removal of odors. The filtered oil particles are less than 3μm in size, and the deodorization efficiency is more than 90%. With the combination of four stages of purification, the oil fume removal efficiency reaches 98%.

[0038] In use, the external click operation component 13 transmits the data to the control system 12. Under the control of the control system 12, the kitchen fumes are drawn into chamber ① by the negative pressure generated by the external exhaust fan. Then, after being purified by the mechanical cyclone separator 14, the fumes enter chamber ②. After being purified by the water film generated by the liquid film generator 15 in chamber ②, the fumes enter chamber ③. After being purified by the differential speed fume separator 16, the fumes enter chamber ④. Finally, after being purified by the UV photolysis deodorizer 17, the fumes are discharged.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
