Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air purification, and in particular to an air purification system based on the Internet of Things. Background Art
[0002] The cooking fumes produced by the catering industry are primarily composed of pollutant particles ranging from 0.01μm to 100μm, formed by the vaporization and cracking of cooking oil and food at high temperatures. Existing electrostatic fume purifiers use the electrostatic purification principle. Exhaust gas containing oil fumes is drawn into the ventilation duct by a fan and enters the pre-filter of the fume purifier. Gravity-inertial purification technology is used to physically separate and evenly rectify large oil mist particles. The separated large oil droplets flow into the oil tank under their own gravity and are discharged. The remaining small oil mist particles, less than 1 micron, enter a high-voltage electrostatic field. This field operates using the electrostatic principle of a two-stage, high- and low-pressure separation. The electric field of the first high-voltage ionization plate converts the small oil mist particles into charged ion particles. These charged ion particles are immediately adsorbed by the second low-pressure adsorption plate and then discharged through the post-filter as clean air.
[0003] However, as the use time of existing electrostatic oil fume purifiers gradually increases, more and more smoke particles accumulate on the adsorption plates, making the oil layer on the adsorption plates thicker and more difficult to clean, resulting in the purifier's oil fume removal effect gradually deteriorating and the oil fume purification efficiency decreasing. Therefore, the adsorption plates need to be disassembled and cleaned frequently. At the same time, since the adsorption plates are expensive and inconvenient to replace directly, the maintenance cost of the purifier is high. Summary of the Invention

Then, the positively charged particles enter the air intake pipe, and the negative ion atomizer can generate a large amount of water mist, and the negative ions in the water mist attract the positively charged particles. , so that the oil fume particles combine with the water mist to form larger mixed particles, and then the mixed particles enter the separation chamber, and under the action of centrifugal force and gravity, the oil and gas separation is completed, thereby reducing the oil fume particles in the gas, reducing the oil fume entering the adsorption chamber, and then reducing the adsorption amount of the adsorption plate. Compared with conventional purifiers, this system realizes the oil and gas separation of small particles of oil fume particles, which helps to reduce the oil stains on the adsorption plate, thereby maintaining the purification system to maintain a good purification effect and high purification efficiency for a long time, while reducing the frequency of cleaning the adsorption plate and reducing the cost of maintenance of the purification system.
[0020] 2. The present application sets a guide cover in the air intake pipe to achieve the purpose of making the negative ion water mist fully contact with the smoke particles. The guide cover is composed of a first cover body and a second cover body. A plurality of guide plates are set on the outside of the second cover body. A straight pipe and a curved pipe are set at the air outlet end of the negative ion atomizer. The curved pipe is aligned with the second cover body. The second cover body is hemispherical. After the water mist is sprayed out from the curved pipe, it is evenly distributed along the second cover body and the first cover body to the inside of the air intake pipe near the pipe wall together with the smoke particles. The system makes the smoke particles and the negative ion water mist evenly distributed through the setting of the guide cover, which helps the smoke particles to combine with the particles in the water mist to form mixed particles, facilitates the discharge of small-particle oil smoke particles, and improves the separation rate of oil and gas separation.

The scraper has a spiral structure and the scraper always fits the inner wall of the conical cylinder. A nozzle is also set inside the separation chamber. The nozzle is connected to the pressure pump through a connecting pipe. The pressure pump pumps the detergent into the nozzle. Since the upper part of the scraper cross section is an inclined surface, the detergent can flow downward along the inner wall of the conical cylinder, making it difficult for oil to adhere. Driven by the driving mechanism, the scraper rotates to scrape down the oil attached to the inner wall of the conical cylinder and discharge it from the bottom of the conical cylinder. Through the above structure, this system can achieve cleaning of the separation chamber, reduce oil pollution, and reduce the cost of maintenance of the purification system.

[0035] Specifically, such as Figure 1 and Figure 8 As shown, the air purification system is equipped with a detection module, a control module, and an execution module. The detection module includes a front oil fume sensor and a rear oil fume sensor, which are respectively located at the air inlet and outlet of the air purification system. The control module includes a controller and a wireless signal transmitter, which is used to communicate with a mobile phone or tablet wireless operating device.

At the same time, the operating status information of the detection module and the execution module can be communicated via the wireless operating device.
[0036] Specifically, such as Figure 1As shown, the separation chamber is composed of a cylindrical body 14 and a conical body 15. The conical body 15 is arranged at the bottom of the cylindrical body 14. An air inlet pipe 6 is arranged on the outside of the cylindrical body 14, and a negative ion atomizer 7 is arranged on the outside of the air inlet pipe 6. The negative ion atomizer 7 can generate a large amount of water mist. The negative ions in the water mist attract the positively charged oil smoke particles, so that the oil smoke particles and the water mist are combined to form larger mixed particles. Subsequently, the mixed particles enter the separation chamber at a faster speed under the blowing of the air intake fan 2. Under the action of centrifugal force and gravity, the mixed particles collide with the cylindrical body 14 and fall down along the conical body 15. The gas is discharged from the separation chamber through the intake pipe 16, thereby completing the oil and gas separation, reducing the oil smoke particles in the gas, and reducing the oil smoke entering the adsorption chamber.
[0037] Specifically, such as Figure 3 As shown, a guide cover is provided inside the air inlet pipe 6, and the guide cover consists of a first cover body 10 and a second cover body 11. A straight pipe 8 located inside the air inlet pipe 6 is provided on the air outlet of the negative ion atomizer 7, and a curved pipe 9 is provided at the open end of the straight pipe 8. The curved pipe 9 and the second cover body 11 correspond to each other and are both arranged along the flow direction of the flue gas. The air inlet pipe 6 is a directional tube, and the first cover body 10 is a quadrangular pyramid structure, one end of which is a circular structure and the other end is a rectangular structure, and the four sides of the rectangular structure are at the same distance from the four inner walls of the air inlet pipe 6. The four side surfaces of the first cover body 10 have curvatures, and guide plates 12 are provided on the four side surfaces. One side of the rectangular structure of the first cover body 10 is fixedly connected to the air inlet pipe 6 through a positioning rod 13. At least two guide plates 12 are provided on one side of the first cover body 10, and the guide plates 12 are diffusely arranged along the direction of the flue gas flow. The function of the guide cover is to make the flue gas and the water mist fully contact and mix, which helps to make small particles of oil smoke combine with water mist to form larger mixed particles, thereby improving the oil and gas separation rate.
[0038] Specifically, such as Figure 4As shown, a scraper 23 and a driving mechanism for driving the scraper 23 to rotate around the central axis of the conical cylinder 15 are provided inside the conical cylinder 15. The scraper 23 is a spiral structure, and the pitch of the spiral structure decreases from top to bottom. The scraper 23 fits the inner wall of the conical cylinder 15. The thickness of the scraper 23 on both sides along the radial direction of the cylindrical cylinder 14 is different. The thickness of the scraper 23 on the side close to the conical cylinder 15 is less than the thickness on the other side. A penetrating connecting pipe 31 is provided on the inner wall of the cylindrical cylinder 14, and a nozzle 30 and a pressure pump are respectively provided at both ends of the connecting pipe 31. The opening of the nozzle 30 faces downward and is fixedly provided on the inner wall of the cylindrical cylinder 14. The driving mechanism includes a mounting rod 18 arranged at the bottom of the conical cylinder 15, and a driving member 19 is provided at the bottom of the mounting rod 18. A transmission shaft 20 is provided at the output end of the driving member 19, and a transmission assembly is provided on the transmission shaft 20 The transmission assembly is transmission-connected with the scraper 23. The transmission assembly includes a sleeve rod 21, a first gear group and a second gear group. The sleeve rod 21 is sleeved on the outside of the transmission shaft 20 and is rotatably connected to the transmission shaft 20. A plurality of fixed rods 22 are fixedly provided on the outside of the sleeve rod 21, and the plurality of fixed rods 22 are fixedly connected to the scraper 23. The first gear group is fixedly provided at the upper end of the sleeve rod 21. The first gear group consists of a first gear 24 and a second gear 25. The second gear group consists of a third gear 26 and a fourth gear 27. The first gear 24 and the second gear 25 are coaxially distributed, and the third gear 26 and the fourth gear 27 are coaxially distributed. The first gear 24 is meshed with the third gear 26, and the second gear 25 is meshed with the fourth gear 27. A support shaft 28 is fixedly provided on the top of the third gear 26, and the support shaft 28 is fixedly connected to the intake pipe 16 through a rotating seat 29. An intake impeller 17 is fixedly provided at the upper end of the transmission shaft 20 . The bottom of the intake pipe 16 extends to the inner upper end of the conical cylinder 15 . The intake impeller 17 is rotatably connected to the bottom of the intake pipe 16 .
[0039] The driving member 19 can directly drive the intake impeller 17 to rotate through the transmission shaft 20 to send the gas in the separation chamber out. The diameter of the first gear 24 is smaller than that of the second gear 25, and the diameter of the third gear 26 is larger than that of the fourth gear 27. The first gear 24 rotates synchronously with the transmission shaft 20, driving the third gear 26 and the fourth gear 27 to rotate accordingly, and further driving the second gear 25 and the sleeve rod 21 to rotate. The rotation speed of the sleeve rod 21 is reduced through the transmission of the two gear sets.
[0040] The scraper 23 rotates under the drive of the driving member 19, and can scrape down the oil stains attached to the inner wall of the cone cylinder 15. At the same time, the pressure pump sends the detergent into the cone cylinder 15. The detergent flows along the scraper 23 to the inner wall of the cone cylinder 15 and flows downward along the scraper 23, so that the detergent evenly contacts the inner wall of the cone cylinder 15, thereby cleaning the separation chamber.
[0041] Specifically, such as Figure 5and Figure 6 As shown, the interior of the adsorption chamber 33 is provided with a plurality of adsorption components distributed at equal intervals from top to bottom, and there are at least four adsorption components. There is a 90° angle between two adjacent adsorption components. The adsorption component includes a first adsorption electrode plate 35, a second adsorption electrode plate 36 and a low-voltage excitation module. The first adsorption electrode plate 35 and the second adsorption electrode plate 36 are both spiral-shaped, and the spacing between the two is the same. The inner sides of the first adsorption electrode plate 35 and the second adsorption electrode plate 36 are fixedly connected by a connecting plate 37. The bottom of the connecting plate 37 is provided with a support base 38 fixedly connected to the adsorption chamber 33. The low-voltage excitation module is connected to the first adsorption electrode plate 35, and the second adsorption electrode plate 36 is grounded. The support base 38 is composed of at least three annular evenly distributed rods.
[0042] When the spiral adsorption plate is adsorbing, there is a small area between the adsorption plate and the inner wall of the adsorption chamber 33 where there is no electric field. This area allows oil fume particles to pass directly through. By providing multiple adsorption components at an angle, unadsorbed oil fume particles can pass through the electric field area of the adsorption plate again, thereby reducing oil fume emissions. The spiral adsorption plate can increase the adsorption area, making it difficult for oil fume particles to escape.
[0043] In summary, the present embodiment provides an air purification system based on the Internet of Things. After the flue gas passes through the pre-filter 1, large particles are filtered out, and smaller particles are ionized and attached with positive charges after passing through the ionization chamber 3. Then the positively charged particles enter the intake pipe 6, and the negative ion atomizer 7 can generate a large amount of water mist. The negative ions in the water mist and the positively charged particles attract each other, so that the oil smoke particles and the water mist are combined to form larger mixed particles. Then the mixed particles enter the separation chamber, and under the action of centrifugal force and gravity, the oil and gas separation is completed. The gas enters the separation chamber 33 along the intake pipe 16 and the delivery pipe 32. The smoke particles remaining in the gas are attached to the adsorption plates under the action of the electric field of the first adsorption electrode plate 35 and the second adsorption electrode plate 36. Finally, the clean gas is discharged through the post-filter 40 to complete the filtration of smoke in the air.
