The present application relates to the technical field of oil fume treatment, and in particular to an array turbulence device and a smoke pipe purification system. The array turbulence device includes a turbulence plate with a plurality of ventilation holes, and the oil fume can pass through the turbulence plate through the ventilation holes.

[0045] Refer to the following Figures 1 to 4 The present invention describes an array turbulence device and a smoke pipe purification system according to some embodiments of the present application.

[0046] Embodiment 1

[0047] Embodiment 1 of the present application provides an array turbulence device, such as Figure 1 and Figure 2As shown, the turbulence plate 1 includes a turbulence plate 1, on which a plurality of ventilation holes 2 are provided, and the length directions of the plurality of ventilation holes 2 extend along the thickness direction of the turbulence plate 1 and penetrate the plate surfaces on both sides of the thickness direction of the turbulence plate 1; the turbulence plate 1 can be used to be arranged in a smoke duct purification system of a range hood, and the plate surface of the turbulence plate 1 is made perpendicular to the flow direction of the oil smoke in the smoke duct purification system, so that the oil smoke can pass through the turbulence plate 1 through the ventilation holes 2 on the turbulence plate 1.

[0048] Combination Figure 4 The direction of the ventilation hole 2 from the air inlet to the air outlet is the flow direction a of the ventilation hole 2, and the cross-section formed by cutting the ventilation hole 2 along the direction perpendicular to the flow direction a is the flow cross section of the ventilation hole 2. Each ventilation hole 2 on the turbulent plate 1 has a gradual flow cross section along the flow direction a, that is, the side wall of the ventilation hole 2 is gradually contracted or expanded along the flow direction a, and each ventilation hole 2 has at least one ventilation hole 2 adjacent to it and in the opposite direction of the gradual change.

[0049] The opposite directions of the gradual changes of the two ventilation holes 2 mean that one of the ventilation holes 2 gradually increases from a smaller air inlet to a larger air outlet along the flow direction a, that is, the flow cross-section gradually increases along the flow direction a, and the other ventilation hole 2 gradually shrinks from a larger air inlet to a smaller air outlet along the flow direction a, that is, the flow cross-section gradually decreases along the flow direction a.

[0050] In this embodiment, preferably, Figure 1 and Figure 2 As shown, multiple ventilation holes 2 are arranged in multiple rows and columns on the turbulence plate 1 along the horizontal and vertical directions of the turbulence plate 1, and the multiple ventilation holes 2 in the same row have the same gradient direction, while the ventilation holes 2 in two adjacent rows have opposite gradient directions, so that the gradient directions of two adjacent ventilation holes 2 in the same column are opposite.

[0051] When the oil fume passes through the gradually expanding ventilation holes 2, the oil fume flows from the air inlet of the ventilation holes 2 to the air outlet, and as the flow cross section gradually increases, the wind speed of the oil fume gradually decreases; and when the oil fume passes through the gradually contracting ventilation holes 2, the oil fume flows from the air inlet of the ventilation holes 2 to the air outlet, and as the flow cross section gradually decreases, the wind speed of the oil fume gradually increases; thereby, when the oil fume passes through two adjacent ventilation holes 2 with opposite gradient directions, a local wind speed gradient will be generated, turbulence will be formed, and turbulent vortices will be generated, so that the oil fume passing through the ventilation holes 2 will be stirred and squeezed, which intensifies the collision of the pollutant particles in the oil fume, and the pollutant particles in the oil fume will experience more friction and collision, which increases the probability of inelastic collision between the pollutant particles, thereby improving the coagulation effect of the pollutant particles with positive and negative charges in the oil fume.

[0052] Preferably, any two adjacent ventilation holes 2 in the plurality of ventilation holes 2 in the same row may also be ventilation holes 2 with opposite gradient directions.

[0053] When the array turbulence device is arranged in the range hood smoke duct purification system, it can be used to assist condensation. At this time, the array turbulence device is arranged between the condensation and charging device and the collection device in the range hood smoke duct purification system; the oil smoke passes through the condensation and charging device, the array turbulence device and the collection device in sequence. The oil smoke first passes through the condensation and charging device. The condensation and charging device will charge the oil smoke, so that the pollutant particles in the oil smoke are charged and become positively or negatively charged particles, and the charged particles will condense due to the electric field force between the positive and negatively charged particles, so that the small-sized pollutant particles in the oil smoke are clustered to form medium-large-sized pollutant particles, which are convenient for the collection device to collect.

[0054] There will still be some uncondensed small-sized charged particles in the oil fume that have passed through the condensation and charging device. When the oil fume reaches the array turbulence device, the oil fume will form turbulence and generate turbulent vortices when passing through the ventilation holes 2 of the turbulence plate 1, which will intensify the collision of pollutant particles in the oil fume and increase the probability of inelastic collision between positively and negatively charged particles in the pollutant particles, so that the small-sized charged particles in the oil fume, i.e., small-sized pollutant particles, will condense and cluster into medium- and large-sized pollutant particles, thereby improving the condensation effect through the array turbulence device, increasing the number of medium- and large-sized oil fume pollutant particles in the oil fume, and further facilitating the collection of pollutant particles in the oil fume by the collection device, thereby improving the oil fume purification effect.

[0055] In this embodiment, preferably, Figure 1 and Figure 2 As shown, the flow cross section of the ventilation hole 2 can be circular or polygonal, and when the flow cross section of the ventilation hole 2 is polygonal, the side wall of at least one side of the ventilation hole 2 has a predetermined inclination angle with the plane where the flow cross section is located, so that the ventilation hole 2 has a gradual flow cross section.

[0056] Preferably, the flow cross section of the ventilation hole 2 is square, and the side walls of one set of opposite sides of the ventilation hole 2, such as the side walls of the left and right sides of the ventilation hole 2, are parallel to each other, that is, the ventilation hole 2 is cut in the horizontal direction to form the following: Figure 3 The other set of side walls of the ventilation hole 2 facing each other, such as the side walls of the ventilation hole 2 on both sides of the vertical direction, have a predetermined inclination angle, that is, the ventilation hole 2 is cut in the vertical direction to form a Figure 4 The trapezoidal cross-section shown facilitates the hole opening process of the turbulent plate 1. At the same time, the gradient ventilation holes 2 also make it convenient for the user to flush the inner wall of the ventilation holes 2 to clean the turbulent plate 1. Regardless of flushing with water or brushing with a brush, the inclined hole wall of the ventilation hole 2 loaded with pollutants is easier to contact and apply force, making cleaning more convenient.

[0057] Preferably, a hole wall is formed between two adjacent ventilation holes 2 of the turbulent plate 1 , and the thickness of the hole wall is less than 1 mm, so as to improve the utilization rate and flow efficiency of the turbulent plate 1 .

[0058] In this embodiment, preferably, the turbulence plate 1 and the hole walls of the ventilation holes 2 are coated with a hydrophobic and oleophobic layer, so that oil stains are not easy to adhere to the turbulence plate 1 and the turbulence plate 1 is easy to clean.

[0059] Preferably, the angle between the inclined side wall of the ventilation hole 2 and the plane where the flow section of the ventilation hole 2 is located is not less than 45°, so that when the user rinses the turbulence plate 1 with water or brushes it with a brush, the inclined hole wall of the ventilation hole 2 loaded with pollutants is easier to contact and apply force, making cleaning more convenient.

[0060] In this embodiment, preferably, the array turbulence device includes a plurality of turbulence plates 1, and the plurality of turbulence plates 1 are arranged side by side and spaced apart along the flow direction of the oil fume, and the spacing between any two adjacent turbulence plates 1 is greater than 5 mm, so that the plurality of turbulence plates 1 assist in agglomerating small-sized charged particles in the oil fume, thereby increasing the number of medium and large-sized oil fume pollution particles in the oil fume, so as to facilitate collection by the collection device and improve the oil fume purification.

[0061] In this embodiment, preferably, the material of the turbulence plate 1 can be a conductive material or the surface of the turbulence plate 1 is coated with a conductive material layer, so that the turbulence plate 1 has conductivity; preferably, the conductive material or the conductive material layer can be a metal, a conductive plastic or a conductive composite material. An electrode connecting device is provided on the turbulence plate 1 so that the turbulence plate 1 can be electrically connected to the output electrode, such as connecting the turbulence plate 1 to a positive high voltage, a negative high voltage or a ground electrode. When the array turbulence device is used as an auxiliary coagulation device, the turbulence plate 1 can be conductive or non-conductive; when the turbulence plate 1 has a guiding property, the turbulence plate 1 can be electrically connected to the ground electrode.

[0062] Embodiment 2

[0063] The array turbulence device in this embodiment is an improvement on the embodiment 1, and the technical contents disclosed in the embodiment 1 are not described repeatedly, and the contents disclosed in the embodiment 1 also belong to the contents disclosed in this embodiment 2.

[0064] The array turbulence device can also be used to collect pollutant particles in the oil fume; when the oil fume passes through the ventilation hole 2, the medium and large particle size pollutant particles in the oil fume have large mass, large inertia of movement, and high viscosity, so that the medium and large particle size pollutant particles will directly collide with and adhere to the inclined side wall of the ventilation hole 2, thereby realizing the collection of the medium and large particle size pollutant particles.

[0065] Preferably, when the array turbulence device is used for collection, a conductive turbulence plate 1 is selected, and the number of turbulence plates 1 can be one or more. When one turbulence plate 1 is set for collection, the turbulence plate 1 can be electrically connected to the ground electrode, and the charged small-sized pollutant particles in the oil smoke will be attracted by the electric field force to move toward the hole wall of the ventilation hole 2, and adhere to the hole wall to complete the collection action, so that both medium and large-sized pollutant particles and small-sized pollutant particles can be collected.

[0066] In order to enhance the collection effect, multiple conductive turbulence plates 1 can be arranged side by side along the flow direction of the oil smoke, and two adjacent turbulence plates 1 are electrically connected to output electrodes of different electrical properties, such as positive + ground, negative + ground, positive + negative or negative + positive. When the oil smoke passes through multiple turbulence plates 1, the condensation and collection of charged particles in the oil smoke will be carried out simultaneously. For example, charged particles with small particle sizes will be condensed on the upper turbulence plate 1, and the particle size will be enlarged. Then, they will collide with the hole wall of the ventilation hole 2 of the turbulence plate 1 of the next layer and adhere to complete the collection, and further enhance the collection and purification effect.

[0067] Embodiment 3

[0068] The array turbulence device in this embodiment is an improvement on the embodiment 1, and the technical contents disclosed in the embodiment 1 are not described repeatedly, and the contents disclosed in the embodiment 1 also belong to the contents disclosed in this embodiment 2.

[0069] The array turbulence device can also be used to charge pollutant particles. In this case, the array turbulence device includes a plurality of conductive turbulence plates 1, and two adjacent turbulence plates 1 are electrically connected to output electrodes of different electrical properties. When the oil smoke passes through the ventilation holes 2 of the turbulence plates 1, the aerosol density of the oil smoke increases instantaneously due to the decrease in the flow area, and the distance between the pollutant particles in the oil smoke decreases, resulting in a large amount of friction and collision between the pollutant particles, resulting in the phenomenon of frictional charging and collision ionization.

[0070] Since the two adjacent hole turbulence plates 1 are electrically connected to the output electrodes with different electrical properties, an equipotential plane and an extremely uneven cushion layer will be formed between the two adjacent hole turbulence plates 1. When the pollutant particles pass through the electric field, the electric field energy will be injected into the molecules or molecular clusters of the pollutant particles, so that the movement speed of the electrons outside the atomic nuclei that make up the atoms is accelerated and the kinetic energy is increased. When the kinetic energy exceeds the chemical bond energy within the molecule, the chemical bond breaks, and the pollutant particles are ionized and become charged particles.

[0071] At the same time, since the adjacent ventilation holes 2 of the turbulent plate 1 have opposite gradient directions, the oil smoke forms a turbulent vortex when passing through the ventilation holes 2, which increases the residence time of some oil smoke pollutant particles in the extremely non-uniform electric field, thereby increasing the charging effect.

[0072] Embodiment 4

[0073] The present application also provides a smoke duct purification system, including a condensation and charging device and a collection device, wherein the condensation device includes the array turbulence device described in Example 3, and the collection device includes the array turbulence device described in Example 2, so that the smoke duct purification system can purify the oil fume and have a good purification effect.

[0074] Embodiment 5

[0075] The present application also provides a smoke duct purification system, including a condensation and charging device, an auxiliary condensation device and a collection device. The oil smoke passes through the condensation and charging device, the auxiliary condensation device and the collection device in sequence, and the condensation and charging device includes the array turbulence device described in Example 3, the auxiliary condensation device includes the array turbulence device of Example 1, and the collection device includes the array turbulence device of Example 2. The condensation and charging device and the auxiliary condensation device can be used to perform evolution pre-treatment on pollutant particles of all particle size segments so as to facilitate collection by the collection device; thereby, the smoke duct purification system can purify the oil smoke and improve the purification effect.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
