Abstract

Technical Field
[0001] The utility model relates to the technical field related to range hoods, and in particular to an oil-water-gas separation structure. Background Art
[0002] There are many ways to cook food, and the emission components are complex and changeable, with high viscosity and difficult to clean. Affected by factors such as cooking oil, cooking methods, dishes, and cuisines, the oil smoke emitted by the catering service industry is a complex organic waste gas with large air volume, low concentration, oily sticky particles, and high water vapor. It is difficult to purify and separate it. Based on the physical phenomenon that gas liquefies when cooled, there is a way to liquefy the oil and water in the oil smoke by condensation to achieve the effect of oil fume purification.
[0003] Existing condensation type oil fume purifiers usually place the condensation plate in the rising path of the oil fume. When the oil fume rises, it contacts the condensation plate, causing the oil and water vapor to liquefy and be removed. However, the amount of oil fume generated by the catering service industry is large. When the oil fume is blocked by the tilted condensation plate, only the uppermost part of the rising oil fume can contact the condensation plate, and the rest of the oil fume will directly bypass the condensation plate. The condensation path of the oil fume is short, and the oil and water vapor in the oil fume cannot be effectively removed. Utility Model Content
[0004] In view of the shortcomings of the prior art, the utility model proposes an oil-water-gas separation structure, which can increase the condensation path, fully condense and liquefy the oil and water gas in the oil fume, improve the oil fume purification efficiency of kitchens in the catering industry, and reduce environmental pollution caused by direct discharge of oil fume.
[0005] The technical solution of the utility model is achieved in this way:
[0006] An oil-water-gas separation structure comprises a shell, in which an oil fume channel for oil fume to pass is formed, in which a condensation component is arranged, the condensation component comprises an evaporator and a pre-filter layer, the pre-filter layer is arranged to cover the bottom end of the evaporator, and the cold energy of the evaporator is transferred to the pre-filter layer to condense and purify the oil fume passing through the pre-filter layer and the evaporator.
[0007] In one embodiment, the evaporator includes a first frame, a plurality of fin groups and at least one condenser tube. The first frame is hollow to form a condenser channel. The fin groups are arranged in between the condenser channels. The cross-sectional shape of the fin groups is wavy. The condenser tube is fixed to the first frame and is arranged through the fin groups.
[0008] In one embodiment, the angle between the evaporator and the horizontal plane is 0° to 45°.
[0009] In one embodiment, the fin group extends along the direction of the condensation channel and is bent in a wave shape.
[0010] In one embodiment, the inlet end of the condenser is connected to a low-temperature tube, the outlet end of the condenser is connected to a high-temperature tube, and a filter for filtering impurities is provided on the high-temperature tube.
[0011] In one embodiment, the interior of the pre-filter layer is covered with ant hole-like structures and is made of metal material.
[0012] In one embodiment, an oil fume interception component is further provided at the inlet end of the oil fume passage, and the oil fume interception component is arranged at the lower side of the condensation component, and the oil fume interception component is inclined to allow liquid droplets to slide off.
[0013] In one embodiment, an oil collecting trough is provided on one side of the oil fume passage, and the oil collecting trough is arranged in the inclined direction of the oil fume interception component to collect falling droplets, and a waste liquid outlet is provided at the bottom of the oil collecting trough.
[0014] In one embodiment, the oil fume interception assembly includes a second frame, an upper plate and a lower plate, wherein the lower plate is spaced apart in the second frame, the middle portion of the lower plate is recessed downward, the upper plate is disposed between the lower plates and the projection area of the upper plate is larger than the spacing between the lower plates, and the middle portion of the upper plate is recessed upward.

[0016] Compared with the prior art, the utility model has the following advantages:
[0017] The embodiment of the utility model arranges a condensation component in the oil fume channel to reduce the temperature of oil gas and water vapor in the process of the oil fume rising through the condensation component, thereby realizing condensation and liquefaction of the oil and water vapor and removing them from the oil fume; the condensation component includes an evaporator and a pre-filter layer, and the cold energy generated by the evaporator is transmitted to the connected pre-filter layer through contact, and the ant cave-like structure in the pre-filter layer can greatly improve the collision path and condensation path between the oil fume and the pre-filter layer. When the high-temperature oil fume passes through the pre-filter layer, it repeatedly collides with the pre-filter layer and condenses and liquefies. As the oil fume continues to rise, the residual oil and water vapor collides and condenses with the fins in the evaporator when passing through the evaporator, and the liquefied droplets are removed from the oil fume. By arranging the evaporator and the pre-filter layer, the condensation path of the oil fume is greatly increased, and the purification of the oil and water vapor is efficiently realized.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0039] See also Figures 1 to 9The utility model discloses an oil-water-gas separation structure, including a shell 1, in which an oil fume channel for oil fume to pass is formed, and a condensation component 2 is arranged in the oil fume channel. The condensation component 2 includes an evaporator 21 and a pre-filter layer 22, and the pre-filter layer 22 is covered and arranged at the bottom end of the evaporator 21. The cold energy of the evaporator 21 is transferred to the pre-filter layer 22 to condense and purify the oil fume passing through the pre-filter layer 22 and the evaporator 21. Specifically, the evaporator 21 is a component that transports low-temperature refrigerant through a copper tube to cool the air flowing through it. The present application sets the evaporator 21 in the oil fume channel through which the oil fume passes, condenses and liquefies the oil gas and water vapor in the oil fume, and reduces the pollution in the oil fume. In order to further increase the collision between the oil fume and the low-temperature metal, the pre-filter layer 22 is fixed on the lower side of the evaporator 21, and the cold on the evaporator 21 can be transferred to the pre-filter layer 22. The honeycomb shape and ant hole shape in the pre-filter layer 22 can effectively increase the internal area, thereby extending the number of collisions between the passing oil fume and the pre-filter layer 22, and achieving more sufficient condensation and purification of the oil fume. It should be noted that the role of the honeycomb and ant hole structures of the pre-filter layer 22 is to increase the number of collisions between the oil fume and the pre-filter layer 22 by increasing the collision area. The structure of the pre-filter layer 22 includes but is not limited to the above two structures. Other structures of the pre-filter layer 22 that can increase the collision area are also within the protection scope of the present application.
[0040] like Figure 4-5 As shown, the evaporator 21 includes a first frame 211, a plurality of fin groups 212 and at least one condensing tube 213. The first frame 211 is hollow to form a condensing channel. The fin groups 212 are arranged in the condensing channel. The cross-sectional shape of the fin groups 212 is wavy. The condensing tube 213 is fixed on the first frame 211 and is arranged through the fin groups 212. A low-temperature refrigerant flows in the condensing tube 213, and the cold energy is transferred to the fin groups 212 intersecting therewith through the condensing tube 213. It can be understood that in the existing air-conditioning evaporator 21, the fin group 212 is in the shape of a straight plate and is arranged perpendicular to the ground. When this evaporator 21 is directly applied to the oil-water gas separation structure in the present application, the oil smoke will directly pass through the condensing channel without blocking, and the oil smoke cannot be fully cooled. Therefore, the present application proposes a fin group 212 with a wavy cross-sectional shape, which extends along the condensing channel and is wavy. The wavy fin group 212 is arranged in the condensation channel, which increases the contact area between the oil smoke and the fin group 212 and prolongs the contact time between the oil smoke and the fin group 212, thereby improving the cooling effect of the oil smoke. In this embodiment, the fin group 212 is arranged at an angle, and the oil smoke will be blocked when it passes through the fin group 212 vertically upward, so that the oil molecules and water molecules in the oil smoke are condensed and liquefied, and condensed into droplets on the fin group 212, thereby making the fin group 212 have the function of blocking oil and water. Figure 3As shown, the angle between the evaporator 21 and the horizontal plane is 0° to 45°. By setting the whole slant, the liquid droplets adhering to the fin group 212 can flow to the bottom and fall naturally under the action of gravity, which reduces the cleaning burden.
[0041] like Figure 8 As shown, in this embodiment, the inlet end of the condenser tube 213 is connected to the low temperature tube 214, and the outlet end of the condenser tube 213 is connected to the high temperature tube 215. The high temperature tube 215 is provided with a filter 216 for filtering impurities. The filter 216 is used to filter impurities in the refrigerant, so that the refrigerant entering the tube flows more smoothly and is not easily blocked, thereby achieving a better cooling effect.
[0042] The pre-filter layer 22 proposed in this embodiment is configured as a velvet mesh made of metal material. The metal material has better thermal conductivity and can effectively transfer the cold generated by the evaporator 21. In addition, since the droplets will adhere to the pre-filter layer 22 when passing through it, the pre-filter layer 22 made of metal material can be more easily cleaned. It should be known to those skilled in the art that the pre-filter layer 22 also includes a grid plate, a grille plate, and other plates with a blocking effect.
[0043] like Figure 3 As shown, the inlet end of the oil fume channel is also provided with an oil fume interception component 3, which is arranged at the lower side of the condensation component 2, and the oil fume interception component 3 is arranged at an angle to allow the droplets to slide off. The function of the oil fume interception component 3 is to initially cool down and separate the oil, water and gas in the oil fume, so as to prevent the high-temperature oil fume from directly contacting the condensation component 2 and causing damage. At the same time, it initially intercepts large particle pollutants in the oil fume, so that the oil, water and gas in the oil fume are separated more fully, and the purification effect is better. Figure 6 As shown, in one embodiment, the oil fume interception assembly 3 includes a second frame 31, an upper plate 32 and a lower plate 33, the lower plate 33 is arranged in the second frame 31 at intervals, the middle part of the lower plate 33 is concave downward, the upper plate 32 is arranged between the lower plates 33, and the projection area of the upper plate 32 is greater than the spacing between the lower plates 33, and the middle part of the upper plate 32 is concave upward. When the oil fume rises, it collides with the low-temperature upper plate 32, condenses and liquefies on the upper plate 32, and falls to the lower plates 33 on both sides under the influence of gravity, and gathers in the concave of the lower plate 33. The oil fume interception assembly 3 is arranged obliquely so that the droplets slide to the oil fume channel. One side is provided with an oil collecting tank 11, and the oil collecting tank 11 is arranged in the oblique direction of the oil fume interception assembly 3 to collect the sliding droplets. The bottom of the oil collecting tank 11 is provided with a waste liquid outlet 12. In this way, the oil and water separated and purified from the oil fume can be tightened more conveniently. In this embodiment, optionally, a semiconductor component is used to realize the cooling of the upper plate 32 and the heat dissipation of the lower plate 33, so that the solidification and flow of the oil fume are faster.
[0044] In another embodiment, the oil fume interception assembly 3 includes a third frame 34 and an oil-slinging plate 35, and the oil-slinging plate 35 is disposed in the third frame 34 to purify the oil fume passing therethrough. It is easy for a person skilled in the art to know that the oil-slinging plate 35 structure used in the present application has a relatively mature solution in the prior art, and will not be described in detail here.
[0045] The embodiment of the utility model sets a condensation component 2 in the oil fume channel, reduces the temperature of oil gas and water vapor in the process of oil fume rising through the condensation component 2, realizes condensation and liquefaction of oil and water vapor, and removes them from the oil fume; the condensation component 2 includes an evaporator 21 and a pre-filter layer 22, the cold energy generated by the evaporator 21 is transmitted to the connected pre-filter layer 22 through contact, the ant cave-like structure in the pre-filter layer 22 can greatly improve the collision path and condensation path of the oil fume and the pre-filter layer 22, the high-temperature oil fume repeatedly collides with the pre-filter layer 22 and condenses and liquefies when passing through the pre-filter layer 22, as the oil fume continues to rise, the residual oil and water vapor collides and condenses with the fins in the evaporator 21 when passing through the evaporator 21, and the liquefied droplets are removed from the oil fume, the condensation path of the oil fume is greatly increased by setting the evaporator 21 and the pre-filter layer 22, and the purification of oil and water vapor is efficiently realized.
[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
