[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figures 1-4 As shown, a condensing fume removal and heat recovery device includes several condensing plates 2 located in the air duct 1 at the head of the integrated stove. The condensing plates 2 are provided with a vortex guiding structure 3 and a resonant sound absorption structure 4. The vortex guiding structure 3 and the resonant sound absorption structure 4 are respectively positioned corresponding to the air duct 1 at the head of the integrated stove. An electric heating device 5 is provided in the air duct 1 at the head of the integrated stove. A thermoelectric power generation and energy storage component 6 is provided on the side of the condensing plates 2 away from the air duct 1 at the head of the integrated stove.

[0031] In this embodiment, several condensing plates 2 are arranged on both sides of the head duct of the integrated stove. A vortex guiding structure 3 is arranged on their surface to guide longitudinal vortices and generate auxiliary oil fume condensation. When the noise generated by the oil fume during its flow propagates in the resonant sound-absorbing structure 4, the sound energy is converted into heat energy and dissipated due to viscous damping, thus achieving noise reduction. When the integrated stove exhaust fan starts working and the oil fume flows through the head duct, the temperature rises, and the phase change energy storage material inside the condensing plate 2 absorbs and stores the heat. When the integrated stove exhaust fan stops working, the temperature drops, causing the phase change energy storage material to undergo a phase change and release the stored heat, raising the temperature on one side of the thermoelectric power generation energy storage component 6, thus achieving thermoelectric power generation. The electrical energy is then transferred to the thermoelectric power generation energy storage component 6 for storage. After a certain period of operation, to prevent excessive oil buildup on the surface of the condensing plates... To improve work efficiency, the electrical energy stored in the thermoelectric power generation and storage component 6 can be used to power the electric heating device 5. The high temperature generated by the electric heating device 5 melts the oil stains that have accumulated on the condenser plate over a long period of time. The electric heating device 5 is arranged in the oil fume flow channel. The longitudinal vortex is guided by the vortex guiding structure 3 on the surface of the condenser plate 2, which hinders the full development of the thermal boundary layer, enhances heat exchange, accelerates the condensation of oil fumes on the surface of the condenser plate 2, and improves the absorption rate of oil fume heat by the phase change energy storage material in the condenser plate 2. It uses the heat energy from the most common catering oil fumes to generate electricity, turning waste into treasure, which is in line with the green and low-carbon development direction and provides another clean source of electricity for residents. In response to the noise generated when oil fumes flow in the flow channel and the noise caused by the longitudinal vortex, the sound energy is converted into heat energy and dissipated through the resonant sound absorption structure 4, thereby achieving the purpose of noise elimination.

[0032] CombinationFigure 2 As shown, the vortex guiding structure 3 includes a plurality of grooves 7 arranged in the condensing plate 2, the plurality of grooves 7 are arranged symmetrically along the center line of the condensing plate 2, and the grooves 7 correspond to the positions of the resonant sound absorption structure 4.

[0033] Specifically, the condensing plate 2 is inlaid in the wall surface of the oil fume flow channel, and the surface is provided with discontinuous grooves 7. When the oil fume flows along the surface of the condensing plate 2, the rotation axis direction of the vortex is parallel to the flow direction of the fluid, and the existence of the longitudinal vortex can disturb the boundary layer, strengthen the mutual mixing of the fluid, hinder the full development of the thermal boundary layer, enhance the heat exchange effect of the oil fume fluid and the condensing plate, and prolong the lag time of the oil fume on the surface of the condensing plate, which is beneficial to the condensation of the oil fume.

[0034] In combination with Figure 1 , Figure 2 As shown, the grooves 7 are arranged obliquely, and the openings of the grooves 7 are directed to one side of the integrated stove head air duct 1.

[0035] In this embodiment, the grooves 7 are arranged obliquely, which can strengthen the mutual mixing of the fluid, hinder the full development of the thermal boundary layer, enhance the heat exchange effect of the oil fume fluid and the condensing plate, and the openings of the grooves 7 are directed to one side of the integrated stove head air duct 1, which is reasonable in structure.

[0036] In combination with Figure 2 As shown, the resonant sound absorption structure 4 includes a plurality of first perforations 8, second perforations 9 and a condensing plate cavity arranged in the condensing plate 2, the first perforations 8 and the second perforations 9 are respectively communicated with the condensing plate cavity, one side of the first perforations 8 is communicated with the condensing plate cavity, and the other side is communicated with the grooves 7, and the first perforations 8 and the second perforations 9 are arranged alternately.

[0037] In this embodiment, in view of the noise generated when the oil fume flows in the flow channel and the noise caused by the longitudinal vortex, the resonant sound absorption structure composed of the first perforations 8, the second perforations 9 and the perforation structure connected with the condensing plate cavity, the internal space of the condensing plate cavity is only communicated with the oil fume flow channel space through the first perforations 8 and the second perforations 9, the sound wave enters the internal space of the condensing plate cavity through the first perforations 8 and the second perforations 9, the air in the perforation moves back and forth to compress the air in the cavity, and due to the effect of viscous damping, the sound energy is converted into heat energy and lost, so that the purpose of eliminating noise is achieved. According to the theoretical model of the micro-perforated plate, the sound impedance rate Z1 of a single perforation is expressed as:

[0038]

[0039] In the formula: is the first-order Bessel function, is the zero-order Bessel function, is the perforation constant, is the air density. is the air density.

[0040] The thermoelectric power storage assembly 6 includes a thermoelectric power sheet 10 and an energy storage device 11 arranged on the side of the condensing plate 2 away from the integrated stove head air duct 1, the thermoelectric power sheet 10 and the energy storage device 11 are connected through a line, the condensing plate 2 is provided with a phase change energy storage material, and the phase change energy storage material is connected with the thermoelectric power sheet 10.

[0041] In this embodiment, the inner cavity of the condensing plate 2 is filled with a phase change energy storage material, and the energy storage principle is to absorb and release energy by the phase change process of the material, and the phase change energy storage material has the characteristics of small temperature change in the process, which is more conducive to the condensation of oil smoke on the surface of the condensing plate. The phase change energy storage material strengthens the condensation of oil smoke on the condensing plate when there is oil smoke, and functions as a power generation component when there is no oil smoke,

[0042] The thermoelectric power sheet 10 is arranged on the side of the condensing plate 2 away from the oil smoke, and when there is oil smoke, the temperature rises, the phase change energy storage material in the condensing plate 2 absorbs heat and stores it, and the absorbed heat comes from the sensible heat of the oil smoke, the latent heat released when the oil smoke condenses, and the heat converted from acoustic energy in the resonance sound absorption structure; when there is no oil smoke, the temperature in the oil smoke flow channel decreases, causing the phase change of the phase change energy storage material to release the stored heat, causing the temperature on one side of the thermoelectric power sheet 10 to rise, realizing thermoelectric power generation, and the energy storage device 11 is connected with the thermoelectric power sheet 10 through a line to store the generated electric energy. Those skilled in the art should understand that the electric heating device 5, the thermoelectric power sheet 10 and the energy storage device 11 are existing components and devices, and their internal structures and working principles will not be described in detail.

[0043] As shown in Figure 1 , Figure 4 , the integrated stove head air duct 1 is provided with an oil ring holder 12 at the bottom, the oil ring holder 12 is provided with an annular oil tank 13, and the bottom of the annular oil tank 13 is provided with a detachable oil plug 14.

[0044] In this embodiment, the oil ring holder 12 is connected with the corresponding outer machine seat of the integrated stove head air duct 1, and the integrated stove air pipe is sleeved on the outer side of the integrated stove head air duct 1. The oil dirt accumulated on the condensing plate 2 for a long time is melted by the high temperature generated by the electric heating device 5, and the oil dirt flows into the annular oil tank 13, avoiding the overflow of the oil dirt. When it is necessary to drain the oil, the detachable oil plug 14 is pulled out, and the cleaning of the oil dirt is convenient and simple.

[0045] The oil ring holder 12 is provided with an annular oil scraping shovel 15 which can move linearly in the vertical direction, the annular oil scraping shovel 15 is arranged staggered with the annular oil tank 13, the oil ring holder 12 is provided with a linear driver 16, and the power shaft of the linear driver 16 is connected with the annular oil scraping shovel 15.

[0046] In this embodiment, when the oil stains on the condensing plate 2 are difficult to melt after long-term use, the linear drive 16 is started to move the annular oil scraping shovel 15 through the power shaft of the linear drive 16, and the oil stains on the condensing plate 2 are scraped off through the annular oil scraping shovel 15, avoiding long-term accumulation and being difficult to clean, maintaining the service life and effect of the parts, reducing the difficulty of manual cleaning, and having high automation. Those skilled in the art should understand that the linear drive 16 is preferably a linear motor.

[0047] The working principle of the present application is:

[0048] The condensing plates 2 are arranged on both sides of the integrated stove head air duct, and the surface is provided with a vortex guide structure 3. The longitudinal vortex is generated to assist the condensation of oil fumes. The noise generated by the oil fumes during the flow process is propagated in the resonance sound absorption structure 4. Due to the action of viscous damping, the sound energy is converted into heat energy and lost, achieving the purpose of eliminating noise. When the integrated stove exhaust fan starts to work, the oil fumes flow through the head air duct, the temperature rises, the phase change energy storage material in the condensing plate 2 absorbs heat and stores it. When the integrated stove exhaust fan stops working, the temperature drops, causing the phase change energy storage material to change phase and release the stored heat, causing one side of the thermoelectric power storage assembly 6 to heat up, realizing thermoelectric power generation, and transmitting the electric energy to the thermoelectric power storage assembly 6 for storage. After working for a certain period of time, in order to prevent the oil stains on the surface of the condensing plate from affecting the working efficiency due to the attachment of too much oil stains, the electric energy in the energy storage device of the thermoelectric power storage assembly 6 is used to power the electric heating equipment 5. The high temperature generated by the electric heating equipment 5 melts the long-term accumulated oil stains on the condensing plate. The electric heating equipment 5 is arranged in the oil fume flow channel. The longitudinal vortex is guided by the vortex guide structure 3 on the surface of the condensing plate 2, the fully developed thermal boundary layer is hindered, the heat exchange is enhanced, the oil fume condensation on the surface of the condensing plate 2 is accelerated, the absorption rate of the phase change energy storage material in the condensing plate 2 to the heat of the oil fume is improved, the heat energy in the most common cooking oil fume in life is used to generate electricity, turning waste into treasure, in line with the direction of green and low-carbon development, providing another clean power source for residents' life. For the noise generated by the oil fumes flowing in the flow channel and the noise caused by the longitudinal vortex, the sound energy is converted into heat energy and lost through the resonance sound absorption structure 4, achieving the purpose of eliminating noise.

[0049] The condensing plate 2 is embedded in the wall surface of the oil fume flow channel, and the surface is provided with discontinuous grooves 7. When the oil fume flows along the surface of the condensing plate 2, the rotation axis direction of the vortex is parallel to the flow direction of the fluid, and the longitudinal vortex exists. The longitudinal vortex can disturb the boundary layer, strengthen the mutual mixing of the fluid, hinder the fully developed thermal boundary layer, enhance the heat exchange effect of the oil fume fluid and the condensing plate, and prolong the lag time of the oil fume on the surface of the condensing plate, which is beneficial to the condensation of the oil fume.

[0050] The grooves 7 are arranged obliquely to strengthen the mutual mixing of fluids, hinder the full development of thermal boundary layer, enhance the heat exchange effect of oil fume and the condensing plate, and the openings of the grooves 7 are directed to one side of the integrated stove head air duct 1, which is reasonable in structure,

[0051] In view of the noise generated by the oil fume flowing in the flow channel and the noise caused by the longitudinal vortex, a resonance sound absorption structure is formed by the first perforation 8, the second perforation 9 and the perforation structure connected with the condensing plate cavity. The internal space of the condensing plate cavity is only communicated with the oil fume flow channel space through the first perforation 8 and the second perforation 9. The sound wave enters the internal space of the condensing plate cavity through the first perforation 8 and the second perforation 9, so that the air in the perforation moves back and forth to compress the air in the cavity. Due to the effect of viscous damping, the sound energy is converted into heat energy and lost, so that the purpose of eliminating noise is achieved. According to the micro-perforated plate theoretical model, the acoustic impedance rate Z1 of a single perforation is expressed as:

[0052]

[0053] In the formula: is the first-order Bessel function, is the zero-order Bessel function, is the perforation constant, is the angular frequency of the sound wave, t is the length of the perforation, is the air density,

[0054] The internal cavity of the condensing plate 2 is filled with phase change energy storage material. The energy storage principle is to absorb and release energy by relying on the phase change process of the material, and the phase change energy storage material has the characteristic of small temperature change in the process, which is more conducive to the condensation of oil fume on the surface of the condensing plate. The phase change energy storage material strengthens the condensation of oil fume on the condensing plate when oil fume passes through, and serves as a power generation functional component when there is no oil fume,

[0055] The thermoelectric power sheet 10 is arranged on the side of the condensing plate 2 opposite to the oil fume. When oil fume passes through, the temperature rises, the phase change energy storage material in the condensing plate 2 absorbs heat and stores it. The absorbed heat comes from the sensible heat of the oil fume, the latent heat released when the oil fume condenses, and the heat converted from sound energy in the resonance sound absorption structure. When there is no oil fume, the temperature in the oil fume flow channel decreases, causing the phase change energy storage material to change phase and release the stored heat, which causes the temperature on one side of the thermoelectric power sheet 10 to rise, realizing thermoelectric power generation. The energy storage device 11 is connected to the thermoelectric power sheet 10 through a circuit to store the generated electric energy,

[0056] The oil ring holder 12 is connected to the corresponding outer device seat of the integrated stove head air duct 1. The integrated stove air pipe is sleeved outside the integrated stove head air duct 1. The oil dirt accumulated on the condensing plate 2 for a long time is melted by the high temperature generated by the electric heating device 5, and the oil dirt flows into the annular oil tank 13 to avoid spillover. When it is necessary to discharge oil, the detachable oil plug 14 can be pulled out, and the oil dirt can be easily and simply cleaned up,

[0057] When the oil stains on the condensing plate 2 are difficult to melt after long-term use, the linear driver 16 is started to move the annular oil scraping shovel 15 through the power shaft of the linear driver 16, and the oil stains on the condensing plate 2 are scraped off through the annular oil scraping shovel 15, avoiding long-term accumulation and being difficult to clean, maintaining the service life and effect of the parts, reducing the difficulty of manual cleaning, and having high automation.
