DETAILED DESCRIPTION

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0053] Figure 1 and Figure 2 As shown, one embodiment of the present invention provides a composite kitchen air filter, the filter comprising:

[0054] Mounting bracket 100;

[0055] A condensation assembly 200 is arranged on the mounting bracket 100, wherein the condensation assembly 200 includes a manifold 210 and a plurality of capillaries 220 fixedly connected to the manifold 210, the manifold 210 and the capillaries 220 are communicated, a plurality of the capillaries 220 are distributed in an array to form a plate shape, and a water outlet interface 230 and a water inlet interface 240 are arranged on the manifold 210 to connect to a water source, and water flowing into the water inlet interface 240 enters the capillaries 220 and flows out from the water outlet interface 230;

[0056] The tail filter assembly 400 is fixedly connected to the mounting bracket 100, and the flue gas enters the tail filter assembly 400 through the condensation assembly 200. The tail filter assembly 400 includes a honeycomb shell 420 and a filler 430 located in the honeycomb shell 420. The honeycomb shell 420 is provided with a plurality of air holes. The filler 430 is granular, and there are gaps between the fillers 430 for gas to flow through.

[0057] The composite kitchen air filter disclosed in the present invention is used in conjunction with a range hood. The filter is installed on the range hood. Under the action of the fan on the range hood, a negative pressure is generated on the side of the tail filter assembly 400 away from the condensation assembly 200. The smoke flows through the condensation assembly 200 and the tail filter assembly 400 driven by the air. The condensation assembly 200 is connected to tap water or low-temperature cooling water (the low temperature refers to lower than or equal to room temperature). The cooling water flows in the condensation assembly 200. When the smoke flows through the capillary tube 220, the water vapor and oil vapor in the smoke are condensed at the capillary tube 220 and attached to the capillary tube 220. After the steam attached to the capillary 220 gathers to a certain extent, it flows into the collection device of the range hood along the capillary 220. The condensation component 200 is used to preliminarily filter the oil smoke in the flue gas. The filtered flue gas enters the tail filter component 400, where it is condensed and adsorbed again to complete the secondary filtration of the oil smoke. Since the gaps between the fillers 430 are small and the fillers 430 are granular, the filtering structure formed by the fillers 430 has a large specific surface area. The oil vapor and water vapor in the flue gas can contact the fillers 430 to the maximum extent, completing the secondary condensation of the oil smoke, thereby further removing the oil vapor and water vapor in the flue gas.

[0058] The composite kitchen air filter disclosed in the embodiment of the present invention is provided with a condensation component 200 and a tail filter component 400. The condensation component 200 can cool the flue gas after cooling water is passed into it, so that the water vapor and oil vapor in the flue gas are condensed and attached to the condensation component 200. The tail filter component 400 can cool the flue gas again and further adsorb the water vapor and oil vapor in the flue gas, thereby completing the filtration of the flue gas. Compared with the traditional structure, the present invention can filter the water vapor and oil vapor in the flue gas and reduce the content of water and oil in the flue gas.
