Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification, in particular to an odor purifier and an oil fume purification device. Background Art

[0002] Currently, the purifier with the best effect in purifying oil fume and odor is the UV purifier. UV purifier refers to the general term for equipment that uses a controller to control the operation of multiple groups of ballasts and UV lamps.

[0003] In existing UV purifiers, the time for gases such as oil smoke that need to be purified to pass through the UV lamp is relatively short, and the amount of odor molecule cracking is small, resulting in low odor purification efficiency. Therefore, existing central range hoods usually use 2-6 UV purifiers at the same time, and each UV purifier usually contains at least 3 branches, and each branch is equipped with 8 groups of ballasts and UV lamps.

[0004] Therefore, the total power of the UV purifier is relatively large during use, and because a single ballast will randomly generate an instantaneous impact current of at least 10 times the rated current when it is started, the UV purifier will interfere with other circuit electrical equipment when it is started, affecting the life of other ballasts or other equipment in the circuit, causing chronic damage to circuit components. When the impact causes the circuit components to be damaged and fail, it will also cause a short circuit, which will cause equipment damage and greatly increase maintenance costs. In addition, since UV lamps will produce excess ozone when they are working, all UV purifiers will also produce a large amount of ozone emitted into the atmosphere when they are working, causing secondary air pollution. Utility Model Content

[0005] The purpose of the utility model is to provide an odor purifier and an oil fume purification device to alleviate the technical problem existing in the prior art that the time for oil fume and other gases to pass through the UV lamp in the existing UV purifier is short, the amount of odor molecule cracking is small, resulting in low odor purification efficiency, and usually 2-6 UV purifiers are needed to purify the oil fume. The more UV purifiers there are, the higher the energy consumption and ozone generation, and the greater the impact on the power grid and the UV lamp.

[0006] In a first aspect, the utility model provides an odor purifier, comprising a housing, an odor removal component and a blocking member:

[0007] The housing is provided with an inlet and an outlet, and the odor removal component is arranged in the housing and located between the inlet and the outlet;

[0008] The blocking member is arranged in the shell, and the blocking member is provided between the odor removal component and the inlet and / or between the odor removal component and the outlet; the blocking member is provided with a flow hole and / or a flow opening is formed between the side of the blocking member and the inner wall of the shell, and the blocking member is used to change the flow rate of the oil fume gas when the oil fume gas passes through the flow hole and / or the flow opening to form gas turbulence.

[0009] In an optional embodiment, there are multiple odor removal components, and the multiple odor removal components are sequentially spaced apart between the inlet and the outlet.

[0010] In an optional embodiment, the odor removal component includes a UV lamp, and the interval between two adjacent odor removal components is 500 mm.

[0011] In an optional embodiment, a plurality of the odor removal components are spaced apart along the length direction of the shell, each of the odor removal components contains a plurality of UV lamp tubes, and the plurality of UV lamp tubes in the odor removal components are spaced apart along the width direction of the shell.

[0012] In an optional embodiment, one blocking member is provided between each group of two adjacent odor removal components, and among the multiple odor removal components, one blocking member is provided between the odor removal component close to the inlet and the inlet, and one blocking member is provided between the odor removal component close to the outlet and the outlet.

[0013] In an optional embodiment, the housing includes a first side wall and a second side wall that are opposite to each other, and the first side wall and the second side wall are both located between the inlet and the outlet;

[0014] In any group of two adjacent blocking members, one of the blocking members is fixed on the first side wall and a flow opening is formed between its side and the inner wall of the shell, and the other blocking member is fixed on the second side wall and a flow opening is formed between its side and the inner wall of the shell.

[0015] In an optional embodiment, the blocking member is in a plate shape.

[0016] In an optional embodiment, the plate surface of the blocking member and the plane where the inlet is located are parallel to or relatively inclined with each other.

[0017] In an optional embodiment, the plate surface of the blocking member is flat or wavy.

[0018] In a second aspect, the utility model provides an oil fume purification device, comprising the odor purifier described in any one of the aforementioned embodiments.

[0019] The odor purifier provided by the utility model includes a shell, an odor removal component and a blocking member: the shell is provided with an inlet and an outlet, the odor removal component is arranged in the shell and is located between the inlet and the outlet; the blocking member is arranged in the shell, and a blocking member is arranged between the odor removal component and the inlet and / or between the odor removal component and the outlet; the blocking member is provided with a flow hole and / or a flow opening is formed between the side of the blocking member and the inner wall of the shell, and the blocking member is used to change the flow rate of the oil fume gas when the oil fume gas passes through the flow hole and / or the flow opening to form gas turbulence. The odor purifier provided by the utility model can be applied to a central range hood or other range hoods that adopt multi-stage purification treatment. During use, the oil fume will first enter the interior of the shell through the inlet of the shell, then flow through the odor removal component and the blocking member, and then flow to the shell outlet and flow through the outlet to the next level of purification processor or the outside. Among them, the flow holes and the flow ports at the blocking member can reduce the cross-sectional area of ​​the shell where the blocking member is located. Therefore, when the flowing oil smoke passes through the blocking member, the blocking member will change the flow rate of the oil smoke gas, so that the oil smoke forms gas turbulence and swirls at the blocking member, thereby extending the moving distance of the oil smoke inside the shell, making the oil smoke stay longer inside the shell, and correspondingly, the oil smoke stays longer at the odor removal component. The odor removal component is used to remove the odor in the oil smoke, and the odor removal component can use a UV (ultraviolet) lamp. Due to the gas turbulence, the oil smoke stays longer at the odor removal component, so the odor removal time is also correspondingly extended, the oil smoke purification effect is better and the purification efficiency is higher. Compared with the existing UV purifier that uses a large number of UV (ultraviolet) lamps to improve the purification effect, the odor purifier provided by the utility model can reduce the number of odor removal components used while ensuring the odor removal effect and purification efficiency, thereby reducing costs, energy consumption and reducing ozone generation, and effectively reducing the impact of the odor removal component on the power grid at the moment of starting the odor purifier. When multiple odor removal components are used, the impact of the odor removal component on other odor removal components can also be reduced. It should be noted that the blocking member in the odor purifier provided in this embodiment can not only prolong the residence time of the oil smoke in the shell, but also because the mass of the molecular clusters in the oil smoke is usually greater than the mass of the molecules in the air, so at the same flow rate, the molecular clusters in the oil smoke have greater inertia and are easier to attach to the blocking member, thereby greatly increasing the oil smoke purification efficiency.

[0020] Compared with the prior art, the odor purifier provided by the utility model can generate gas turbulence during the flow of oil smoke through the blocking member, thereby extending the movement distance of the oil smoke inside the odor purifier shell, making the oil smoke stay in the odor removal component for a longer time, thereby improving the purification efficiency and reducing the number of odor removal components used. It can not only reduce energy consumption and ozone generation, but also reduce the impact of the odor removal component on the power grid and other odor removal components at the moment of startup, thereby improving the reliability and stability of the odor purifier.

[0021] The oil fume purification device provided by the utility model comprises the above-mentioned odor purifier, so the oil fume purification device has the same beneficial effects as the above-mentioned odor purifier. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0031] Example:

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, the odor purifier provided in this embodiment includes a shell 1, an odor removal component 2 and a blocking member 3: the shell 1 is provided with an inlet and an outlet, the odor removal component 2 is arranged in the shell 1 and is located between the inlet and the outlet; the blocking member 3 is arranged in the shell 1, and a blocking member 3 is arranged between the odor removal component 2 and the inlet or between the odor removal component 2 and the outlet, or, a blocking member 3 is arranged between the odor removal component 2 and the inlet or between the odor removal component 2 and the outlet; the blocking member 3 is provided with a flow hole or a flow opening 30 is formed between the side of the blocking member 3 and the inner wall of the shell 1, or, the blocking member 3 is provided with a flow hole and a flow opening 30 is formed between the side of the blocking member 3 and the inner wall of the shell 1, and the blocking member 3 is used to change the flow velocity of the oil fume gas when the oil fume gas passes through the flow hole and the flow opening 30 to form gas turbulence.

[0033] The odor purifier provided in this embodiment can be applied to central range hoods and other range hoods that adopt multi-stage purification treatment. During use, the oil smoke will first enter the interior of the shell 1 through the inlet of the shell 1, then flow through the odor removal component 2 and the blocking member 3, and then flow to the outlet of the shell 1 and flow through the outlet to the next level of purification processor or the outside world.

[0034] Among them, the flow holes and the flow port 30 at the blocking member 3 can reduce the cross-sectional area of ​​the shell 1 where the blocking member 3 is located. Therefore, when the flowing oil smoke passes through the blocking member 3, the blocking member 3 will change the flow rate of the oil smoke gas, so that the oil smoke will form gas turbulence and swirl at the blocking member 3, thereby extending the movement distance of the oil smoke inside the shell 1, making the oil smoke stay longer inside the shell 1, and correspondingly, the oil smoke will stay longer at the odor removal component 2.

[0035] The odor removal component 2 is used to remove the odor in the oil fume. The odor removal component 2 can use a UV (ultraviolet) lamp tube. The UV lamp tube 20 can remove the odor molecules in the oil fume through a photolysis reaction, thereby achieving the odor removal effect. Due to the gas turbulence, the oil fume stays at the odor removal component 2 for a longer time, so the odor removal time is correspondingly extended, the oil fume purification effect is better, and the purification efficiency is higher. Compared with the existing UV purifier that uses a large number of UV (ultraviolet) lamp tubes to improve the purification effect, the odor purifier provided in this embodiment can reduce the number of odor removal components 2 used while ensuring the odor removal effect and purification efficiency, thereby reducing costs, energy consumption and ozone generation, and effectively reducing the impact of the odor removal component 2 on the power grid at the moment of starting the odor purifier. When multiple odor removal components 2 are used, the impact of the odor removal component 2 on other odor removal components 2 can also be reduced.

[0036] It should be noted that the blocking member 3 in the odor purifier provided in this embodiment can not only prolong the residence time of the oil fume in the shell 1, but also because the mass of the molecular clusters in the oil fume is usually greater than the mass of the molecules in the air, therefore at the same flow rate, the molecular clusters in the oil fume have greater inertia and are easier to attach to the blocking member 3, thereby greatly increasing the oil fume purification efficiency.

[0037] Compared with the prior art, the odor purifier provided in this embodiment can generate gas turbulence during the flow of oil smoke through the blocking member 3, thereby extending the movement distance of the oil smoke inside the odor purifier housing 1, allowing the oil smoke to stay in the odor removal component 2 for a longer time, thereby improving the purification efficiency and reducing the number of odor removal components 2 used. It can not only reduce energy consumption and ozone generation, but also reduce the impact of the odor removal component 2 on the power grid and other odor removal components 2 at the moment of startup, thereby improving the reliability and stability of the odor purifier.

[0038] like Figure 1 and Figure 2 As shown, there are multiple odor removal components 2, and the multiple odor removal components 2 are sequentially spaced between the inlet and the outlet.

[0039] A plurality of odor removal components 2 can improve the purification efficiency of the odor purifier for oil smoke, and a plurality of odor removal components 2 are arranged in sequence at intervals to prevent the odor removal components 2 from being arranged adjacently and interfering with each other, which not only has a limited effect on improving the purification efficiency, but also easily increases energy consumption.

[0040] Furthermore, the odor removal component 2 includes a UV lamp tube 20, and the interval between two adjacent odor removal components 2 is 500 mm.

[0041] Since the UV lamp tube 20 removes odor molecules in the oil smoke through photolysis reaction, and the UV lamp tube 20 has the best odor removal effect when the radiation range is 250 mm, the optimal spacing between two adjacent UV lamp tubes 20 is 500 mm. Based on this, when the odor removal component 2 includes the UV lamp tube 20, the preferred spacing between two adjacent odor removal components 2 in this embodiment is 500 mm.

[0042] Further, such as Figure 1 and Figure 2 As shown, multiple odor removal components 2 are spaced apart along the length direction of the shell 1 , there are multiple UV lamp tubes 20 in each odor removal component 2 , and the multiple UV lamp tubes 20 in the odor removal component 2 are spaced apart along the width direction of the shell 1 .

[0043] When there are multiple UV lamp tubes 20 in the odor removal component 2, the interval between two adjacent UV lamp tubes 20 in the odor removal component 2 is preferably 500 mm.

[0044] It should be noted that the odor removal component 2 may further include a lamp tube rack 21 , and the multiple UV lamp tubes 20 in the odor removal component 2 are fixed on the lamp tube rack 21 in sequence along the width direction of the housing 1 .

[0045] Specifically, the lamp tube frame 21 may be provided with a mounting hole or a mounting groove, and the end of the UV lamp tube 20 is inserted and fixed in the mounting hole or the mounting groove.

[0046] In this embodiment, if Figure 2 As shown, a blocking member 3 is provided between each group of two adjacent odor removal components 2, and among the multiple odor removal components 2, a blocking member 3 is provided between the odor removal component 2 close to the inlet and the inlet, and a blocking member 3 is provided between the odor removal component 2 close to the outlet and the outlet. This arrangement enables blocking members 3 to be provided on both sides of each odor removal component, which can not only effectively increase the turbulence phenomenon to further improve the purification effect, but also allows the oil smoke to contact a blocking member 3 before reaching each odor removal component 2, so that the blocking member 3 intercepts the molecular clusters in the oil smoke before the odor removal component 2, and prevents the oil smoke molecular clusters from being attached to the odor purification component in large quantities and affecting its use effect.

[0047] It should be noted that, since the odor removal effect of the UV lamp tube 20 is best when the radiation range is 250 mm, in order to prevent the blocking member 3 from being too far away from the odor removal component 2 and unable to affect the residence time of the oil smoke in the odor removal component 2, the preferred spacing between the blocking member 3 and the adjacent odor removal component 2 in this embodiment is 250 mm.

[0048] It should also be noted that, based on the influence of oil fume purification efficiency, the distance between the blocking member 3 and the adjacent odor removal component 2 is not limited to 250 mm. In order to improve the purification effect, the distance between the blocking member 3 and the adjacent odor removal component 2 can also be less than 250 mm.

[0049] like Figure 2 As shown, the housing 1 includes a first side wall 10 and a second side wall 11 that are opposite to each other, and the first side wall 10 and the second side wall 11 are both located between the inlet and the outlet; in any group of two adjacent blocking members 3, one blocking member 3 is fixed on the first side wall 10 and a flow opening 30 is formed between its side and the inner wall of the housing 1, and the other blocking member 3 is fixed on the second side wall 11 and a flow opening 30 is formed between its side and the inner wall of the housing 1. This arrangement allows multiple blocking members 3 to be staggered on the first side wall 10 and the second side wall 11, so that the blocking members 3 are distributed approximately in an S shape between the upper inlet and the outlet, which can not only improve the distribution balance of the turbulence formed by the oil smoke in the housing 1, but also expand the distribution range of the turbulence, thereby effectively improving the oil smoke purification effect.

[0050] In this embodiment, the blocking member 3 may be in a plate shape.

[0051] When the blocking member 3 is in a plate shape, the space occupied by the blocking member 3 in the housing 1 can be effectively reduced, thereby preventing the blocking member 3 from being too large and affecting the oil fume purification efficiency.

[0052] Furthermore, the plate surface of the blocking member 3 and the plane where the inlet is located can be parallel to each other, and the plate surface of the blocking member 3 and the plane where the inlet is located can also be arranged to be relatively inclined. Since when the plate surface of the blocking member 3 and the plane where the inlet is located are parallel to each other, the oil smoke at the inlet will flow vertically to the plate surface of the blocking member 3, so that the blocking member 3 has the best blocking effect on the oil smoke, and the oil smoke is more likely to form a disordered and larger range of turbulence. Therefore, in this embodiment, it is preferred that the plate surface of the blocking member 3 and the plane where the inlet is located are parallel to each other.

[0053] Correspondingly, when the shell 1 is in the shape of a cuboid, the blocking member 3 and the side wall of the shell 1 may be vertically connected.

[0054] In addition, there is no limitation on the arrangement of the plate surface of the blocking member 3. For example, the plate surface of the blocking member 3 can be flat or wavy.

[0055] It should also be noted that when a flow opening 30 is formed between the side of the blocking member 3 and the inner wall of the housing 1 , the blocking member 3 may or may not be provided with a flow hole.

[0056] When the blocking member 3 is provided with flow holes, the number of the flow holes is not limited, as long as the blocking member 3 can block the flow and make the oil smoke form turbulence. For example, the blocking member 3 can be provided with a large number of flow holes, and the blocking member 3 adopts a filter mesh structure.

[0057] In this embodiment, there is no restriction on the material of the blocking member 3. However, since the oil smoke is corrosive, in this embodiment, it is preferred that the blocking member 3 be made of a corrosion-resistant material, or the surface of the blocking member 3 is covered with a rust-proof layer.

[0058] like Figure 4 As shown, this embodiment also provides an oil fume purification device, which includes the above-mentioned odor purifier. Therefore, the oil fume purification device and the above-mentioned odor purifier can solve the same technical problems and achieve the same technical effects, which will not be repeated here.

[0059] It should be noted that the oil fume purification device may also have a multi-stage purification function, correspondingly, Figure 4 As shown, the oil fume purification device also includes an electrostatic purifier 4, an electrostatic purification controller 40, a reducer 5, an adsorption filter 6, a fan 7, and a muffler 8. The electrostatic purifier 4, the odor purifier, the reducer 5, the adsorption filter 6, the fan 7, and the muffler 8 are connected in sequence, the electrostatic purifier 4 is used to adsorb oil droplets in the oil fume, the electrostatic purification controller 40 is installed at the electrostatic purifier 4 and is electrically connected to the electrostatic purifier 4, and the electrostatic purification controller 40 is used to control the operation of the electrostatic purifier 4.

[0060] The side of the electrostatic purifier 4 away from the odor purifier can also be connected to a smoke inlet pipe 41, and the pipe opening of the smoke inlet pipe 41 away from the electrostatic purifier 4 is the total smoke inlet of the oil fume purification device; the side of the muffler 8 away from the fan 7 can be connected to a smoke exhaust pipe 80, and the pipe opening of the smoke exhaust pipe 80 away from the muffler 8 is the total exhaust outlet of the oil fume purification device.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
