Technical Field

[0001] This utility model relates to the field of food cooking technology, and in particular to an oil fume purification system for a high-speed oven. Background Technology

[0002] Currently available oil fume purification equipment is either too bulky to fit small commercial settings, or its purification performance is insufficient to meet environmental protection requirements, resulting in the direct emission of large amounts of untreated oil fumes. This not only pollutes the surrounding environment but may also cause safety hazards due to the accumulation of oil fumes, while also affecting the store's operating experience and customer satisfaction.

[0003] Existing fume purification systems on the market suffer from serious compatibility issues. Due to the unique requirements of quick-cooking ovens in terms of structural design, functional layout, and space planning, general-purpose fume purification equipment is difficult to directly integrate. Even if it is installed, problems such as poor airflow and poor purification effect will occur, limiting the market competitiveness of self-developed quick-cooking ovens. Based on the above-mentioned technical problems, this utility model proposes an oil fume purification system for a fast-roasting oven. Utility Model Content

[0016] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] Example 1 like Figure 1-4 As shown, an oil fume purification system for a fast-roasting oven includes a fast-roasting oven housing 1, a heating inner liner 8 installed inside the fast-roasting oven, an oil fume purification unit installed behind the inner liner 8, and an air circulation unit installed between the oil fume purification unit and the inner liner. The air circulation unit is an integrated circulating fan. A control unit 7 is installed inside the fast-roasting oven to provide a stable control algorithm for the self-developed fast-roasting oven. Furthermore, the purification system integrates an intelligent control system, which is integrated into the main control panel of the self-developed fast-roasting oven.

[0019] The enclosure 1 is made of stainless steel, which has high structural strength, is corrosion resistant and not easy to rust. The surface of the outer shell 1 is machined with heat dissipation holes 11 for heat dissipation of the equipment. The control panel 2 is installed on the front of the enclosure 1.

[0020] Oil fume purification units include wet purification units and dry purification units.

[0021] The wet purification unit includes a water washing tank 4, which is installed behind the inner liner 8. The shape, size, and installation position of the water washing tank 4 are designed according to the internal spatial structure of the self-developed high-speed oven to ensure a tight fit with the oven, thereby optimizing the internal layout. A dedicated dry purification unit duct is designed based on the exhaust duct routing of the self-developed high-speed oven. This dry purification unit is a three-way catalytic converter 5, ensuring that the oil fumes purified by the wet process can smoothly enter and evenly pass through the three-way catalytic converter 5 within the duct. The three-way catalytic converter 5 is filled with a catalyst suitable for the oil fume components of the high-speed oven, effectively improving the catalyst's catalytic decomposition ability for residual harmful pollutants and odor substances, ensuring a secondary purification effect.

[0022] The air circulation unit includes a fan 3 and connecting pipes. It requires a fan whose power and air volume are matched with the self-developed fast oven. The interface design of the fan 3 and the fast oven housing 1 and the purification unit connecting pipes is optimized to reduce airflow resistance and ensure efficient extraction and transmission of oil fumes.

[0023] In this embodiment, the fumes generated during the use of the quick-roasting oven enter the wet purification unit via a circulating fan. After wet purification, the fumes enter the dry purification unit for secondary purification. The air inlet of the fan 3 is connected to the inner liner 8 of the quick-roasting oven, and the air outlet is connected to the water washing tank 4 of the wet purification unit. The fan 3 is installed on the bottom wall of the quick-roasting oven. The air inlet of the fan 3 is connected to the bottom wall of the inner liner 8 via pipe 31. The fumes generated in the inner liner 8 are transmitted by the fan 3 and enter the water washing tank 4 of the wet purification unit via pipe 32.

[0024] A smoke inlet is opened at the top of the washing tank 4. Pipe 2 32 is installed inside the washing tank 4 through the smoke inlet. Pipe 2 32 and the washing tank 4 are sealed with a sealant. The washing tank 4 is installed on the tank body 1. A water inlet pipe 43 is installed at the bottom of the washing tank and is connected to an external water supply device. An overflow pipe 41 is installed on the upper side wall of the washing tank 4 and is connected to an external collection box. The grease in the washing tank 4 flows out from the overflow pipe 41 and enters the grease collection box. The grease collection box and the washing tank 4 are sealed together and the grease collection box is a closed chamber. The height of the overflow pipe 41 is above the liquid level of the washing tank 4, and the air inlet pipe of the washing tank 4 is below the liquid level.

[0025] An air distribution pipe 33 is installed at the air inlet end of the second pipe 32 inside the water washing tank 4. The air distribution pipe 33 is made of flexible hose, so that the oil fumes can be dispersed in the water washing liquid after entering the water washing liquid, thereby achieving efficient interception and preliminary purification of oil particles and some odor substances in the oil fumes.

[0026] A water level detector 42 is installed at the top of the washing tank 4. The water level detector 42 can detect the water level of the washing liquid in real time. When the water level of the washing liquid is low, water is automatically replenished through the water inlet pipe 43 at the bottom of the washing tank 4. After the set number of water replenishments is exceeded, the system will automatically control the water replenishment device to add too much water to the washing tank 4, so that the liquid level is about 5 mm higher than the opening of the overflow pipe 41. Since the density of e-liquid is lower than that of water, when the liquid level rises, the e-liquid in the washing tank can flow out through the overflow pipe 41, realizing the self-cleaning of the washing tank. During the self-cleaning process of the washing tank, the controller controls the water replenishment device to slowly replenish water. The self-cleaning time lasts for 2 minutes to ensure the cleaning effect.

[0027] After the oil fumes are washed and purified by the water washing box 4, a large number of oil droplets and soot particles are trapped by the washing liquid. The odor in the oil fumes and harmful substances such as carbon monoxide and organic matter produced by combustion that cannot be decomposed by the water washing box enter the three-way catalytic unit 5 through the pipe 344 at the top of the water washing box 4. The three-way catalytic unit uses the three-way catalytic catalyst to decompose the remaining harmful pollutants such as polycyclic aromatic hydrocarbons in the oil fumes and convert them into pollution-free gas that enters the ventilation chamber 6. The purified gas enters the inner liner 8 for recirculation.

[0028] After multiple experiments, the synergistic mechanism of wet water washing purification and dry three-way catalytic purification was studied, the optimal connection parameters between the two were determined, and the humidity and temperature control range of the oil fume after wet purification was controlled by the environmental control device 61. The best supplier was selected to improve the catalyst's ability to catalytically decompose the remaining harmful pollutants and odors, and to ensure the catalytic efficiency of the dry purification unit is maximized. Through reasonable design, the oil particle removal rate is ≥90%, the odor removal rate is ≥85%, and the removal rate of harmful pollutants (such as polycyclic aromatic hydrocarbons) is ≥85%.

[0029] In terms of space utilization, an embedded integrated design is adopted, making the overall volume of the purification system ≤10,000 cubic centimeters. It can be completely embedded in the reserved space of the self-developed high-speed oven without occupying additional commercial space. Develop an intelligent control system suitable for this purification system and integrate it into the main control panel of the self-developed high-speed oven. This system will monitor key parameters such as the water level of the washing liquid and the operating status of the circulating fan in real time, thereby enabling intelligent operation and fault early warning of the system.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
