Description

Technical Field

[0001] The utility model belongs to the technical field of oil fume purification, and in particular relates to a composite oil fume removal and purification device. Background Art

[0002] With the rapid development of the modern catering industry, the problem of oil fume pollution generated during cooking has become increasingly prominent, becoming a major factor affecting environmental quality and public health. In my country, traditional cooking methods mainly rely on frying, stir-frying, grilling, and deep-frying. While these cooking methods impart unique flavors to food, they inevitably cause the oil to produce large amounts of oil fume and particulate matter at high temperatures. Under normal circumstances, the oil temperature can reach 230-250°C. Under such high temperatures, the water in the ingredients evaporates rapidly and mixes with the oil to form a complex oil fume mixture containing a variety of harmful components such as oil fume molecules, particulate matter, and non-methane hydrocarbons. These pollutants not only affect air quality but also pose potential threats to human health, such as irritating the respiratory tract and aggravating cardiopulmonary diseases.

[0003] While traditional fume purification equipment is currently widespread in the market, its technical limitations are gradually becoming apparent. Filter-type purifiers are prone to clogging when exposed to high concentrations of fume. While electrostatic purifiers can effectively capture some fume particles, their removal of fine particulate matter and volatile organic compounds is limited, making comprehensive purification difficult. Consequently, emissions continue to exceed standards. Furthermore, some fume purification equipment relies on frequent filter replacement or electrode cleaning to maintain performance. This not only increases operational costs but can also lead to new problems due to improper maintenance. For example, if cleaning is not thorough, oil can accumulate on the electrodes. This oil can burn at high temperatures, releasing harmful gases and exacerbating environmental pollution.

[0004] Therefore, we propose a composite oil fume removal and purification device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See Figure 1 and Figure 2 The utility model provides a composite oil fume removal and purification device, comprising a purifier housing 1, the front and rear ends of the purifier housing 1 are respectively an air inlet and an air outlet, a high-speed centrifuge 2 is installed in the purifier housing 1 on the air inlet side, and an atomization component 3 and a condensation net are respectively installed on the front and rear sides of the high-speed centrifuge 2, an ionization control component 5 is installed in the purifier housing 1 on the air outlet side, and an oil-water separation box 6 is detachably connected to the bottom of the ionization control component 5 of the purifier housing 1, and the oil-water separation box 6 is communicated with the purifier housing 1.

[0025] After the purification device is installed, the air inlet is aimed at the source of oil smoke, such as a stove, while the air outlet is directed outdoors or into a well-ventilated indoor area, effectively preventing oil smoke backflow. During the cooking process, ingredients rapidly release water at high temperatures, forming a large number of oil smoke molecules and particulate matter. These harmful substances are entrained by the flowing gas and become pollutants that urgently need to be treated. At this point, the purification device is manually activated or automatically activated, and the high-speed centrifuge 2 immediately operates, using its powerful suction to draw the oil smoke mixture into the device. Through the synergistic action of the high-speed centrifuge 2 and the atomization assembly 3, the oil smoke mixture encounters a fine water mist. Most of the oil smoke particles, due to inertial impact, tightly bind to the atomized water molecules and condensate. They are then further cooled and liquefied by the cooling effect of the condenser 4. During this process, the oil smoke molecules and particles serve as growth nuclei, and the liquid layer covering their surface significantly enhances their capture efficiency. Through physical action, they transform from a gaseous state to a liquid state. Ultimately, due to the viscosity and surface tension of the liquid water, they converge and are discharged into the oil-water separation tank 6 below. For the few oil fume mixtures that still escape physical capture, they continue to move forward to the ionization control component 5. Here, the high-voltage electric field further purifies the oil fume through ionization, decomposition, adsorption and carbonization processes, thereby ensuring that the oil fume does not leak out. Compared with traditional oil fume purification technology, this composite oil fume purification device adopts multiple purification mechanisms to ensure that oil fume and various harmful gases are efficiently purified, meet environmental protection regulatory standards, effectively reduce the pollution of oil fume emissions to the environment, and conform to the green ecological concept. In addition, the atomization component 3 can not only provide water mist to participate in the oil fume purification process, but also can be used to flush the high-speed centrifuge 2, effectively extending the maintenance cycle of the purification device, greatly reducing the cleaning frequency and operating costs, and providing an economical and efficient solution to the problem of oil fume control.

[0026] In a specific embodiment, see Figure 1 The atomizing assembly 3 includes a spray bracket A301 and a spray bracket B302, which are respectively arranged on the front and rear sides of the high-speed centrifuge 2, and the spray bracket B302 is located in front of the condensation net. The spray bracket A301 and the spray bracket B302 are both provided with multiple atomizing nozzles.

[0027] Spray brackets A301 and B302 are positioned on the front and rear sides of high-speed centrifuge 2, respectively. This allows the oil fume mixture to come into contact with the water mist multiple times as it passes through high-speed centrifuge 2, increasing the chances of collision between oil fume particles and the atomized medium, thereby improving the efficiency of oil fume purification. Furthermore, the water mist sprayed from spray bracket A301 also helps clean high-speed centrifuge 2, while the water mist sprayed from spray bracket B302 not only cleans high-speed centrifuge 2 but also the condensation screen, effectively reducing the adhesion of oil fume to the equipment, thereby reducing cleaning frequency, lowering the operating costs of the purification device, and maintaining the cleanliness and efficient operation of the purification equipment.

[0028] In a specific embodiment, see Figure 1 The ionization control component 5 includes a high-voltage electric field generator A501 and a high-voltage electric field generator B502, and the high-voltage electric field generator A501 and the high-voltage electric field generator B502 are arranged at intervals inside the purifier housing 1.

[0029] The high-voltage electric field generator utilizes conventional technology from the prior art, primarily comprising ionization electrodes, a high-voltage power supply, a control system, and insulation and protection devices. The operating principle of the ionization control assembly 5 can be summarized as follows: When cooking fume enters the ionization zone, the ionization electrode, under the action of the high-voltage power supply, releases an electric charge, causing the particulate matter in the cooking fume to become charged. These charged particles, under the influence of the electric field, migrate toward the collector and are trapped there, thus preventing the cooking fume from escaping. However, as particulate matter accumulates, the oil contamination on the collector gradually increases, requiring regular cleaning to maintain the equipment's purification efficiency and service life. The dual purification mechanism implemented by high-voltage electric field generators A501 and B502 ensures that cooking fume particles and micro-particles are fully charged during the ionization process, enabling them to be effectively adsorbed and thus enhancing purification effectiveness. Furthermore, the load pressure on individual high-voltage electric field generators is effectively distributed, reducing the risk of performance degradation or failure caused by prolonged high-load operation and improving the user experience.

[0030] In a specific embodiment, see Figure 1 The purifier housing 1 is provided with a water filter assembly on the front side of the ionization control assembly 5 , and the water filter assembly is composed of two water filter nets 7 arranged at intervals.

[0031] When oil smoke passes through the ionization control assembly 5, it may carry some incompletely condensed water mist. The water filter assembly is arranged in front of the ionization control assembly 5 with two water filter screens 7 spaced apart, effectively intercepting this water mist. This prevents the risk of corrosion or even damage to the ionization control assembly 5 from contact with the water mist, and protects the electrical safety of the purification device's internal structure.

[0032] In a specific embodiment, see Figure 1 The side of the air inlet side of the purifier housing 1 is provided with an opening, and a box door panel 8 matching the opening is detachably connected.

[0033] The door panel 8 allows users to easily open the purifier housing 1, thereby exposing the components inside the purifier housing 1, making it convenient to perform necessary cleaning and maintenance operations on these components, thereby helping to extend the use effect and service life of the purifier and providing users with a more lasting and efficient purification experience.

[0034] In a specific embodiment, see Figure 2The inner bottom wall of the purifier housing 1 is provided with a guide rail groove 9 below the atomizing assembly 3, the high-speed centrifuge 2 and the condensation net. The guide rail groove 9 is provided with a notch 10, and baffles 11 are provided behind both sides of the guide rail groove 9.

[0035] On the premise of setting the box door panel 8 on the side of the purifier housing 1, the internal guide groove 9 can make key components such as the atomization assembly 3, high-speed centrifuge 2 and condensation network easily slide into the predetermined position and be fixed by the baffle 11, realizing modular installation and making the purification device more stable and reliable during operation. This installation method not only simplifies the installation process, but also makes subsequent maintenance and replacement work easier and faster. The notch 10 on the guide groove 9 allows the condensed and liquefied water droplets to pass through and finally enter the oil-water separation box 6.

[0036] In a specific embodiment, a plurality of collecting ports are provided on the inner bottom wall of the purifier housing 1 above the oil-water separation box 6 , and the inner bottom wall of the purifier housing 1 is inclined along the collecting ports.

[0037] Through this design, the condensed water droplets generated during the purification process can flow more smoothly along the inclined surface to the collection port, reducing the residence time of the water droplets on the bottom wall, thereby improving the collection efficiency and facilitating the subsequent further processing and separation of the oil-water mixture.

[0038] In a specific embodiment, the top surface of the oil-water separation box 6 is open, and flanges facing the openings are provided on both sides, and a slide matching the flanges is provided below the purifier housing 1 .

[0039] The combination of the flange and the chute simplifies the disassembly and installation steps of the oil-water separation box 6 and the purifier housing 1, making it easy to disassemble the oil-water separation box 6 independently, facilitating in-depth maintenance or cleaning operations. Users can also more intuitively inspect the interior of the oil-water separation box 6, promptly clean accumulated dirt and residue, and keep the equipment clean and hygienic, thereby extending the service life of the equipment. In addition, a discharge pipe interface can be directly reserved at the bottom of the oil-water separation box 6, allowing the user to directly discharge the water at the bottom through the discharge pipe after the oil-water separation process is completed. This not only facilitates subsequent oil pollution cleanup work, but also enables the recycling of water resources.

[0040] In a specific embodiment, the condenser 4 is made of a stainless steel condensation mesh.

[0041] The stainless steel condensation screen has excellent thermal conductivity. After the oil fume particles tightly bind with the atomized water molecules and condensate, they are cooled and liquefied more effectively through the cooling effect of the stainless steel condensation screen. The stainless steel condensation screen also has excellent corrosion resistance and can resist the corrosive substances that may be contained in the oil fume, ensuring the stable operation of the equipment in harsh working environments.

[0042] In a specific embodiment, see Figure 1 The purifier housing 1 is provided with an air distribution net 12 at one end of the air inlet.

[0043] The air distribution net 12 can effectively distribute the air entering the purifier evenly, ensuring that the air flow rate and flow rate in all directions remain consistent, improving the uniformity and efficiency of air flow, and thus improving the overall performance of the purifier.
