Description

Technical Field

[0001] This invention relates to the field of oil fume purification equipment technology, and more specifically, to an oil fume purification device. Background Technology

[0002] There are typically two methods for purifying fumes in hot pot or barbecue restaurants. The first is direct exhaust, which uses a high-speed motor to create negative pressure, drawing in fumes and venting them outdoors. The second is self-purification, which integrates the hot pot table with the motor, ductwork, and filtration devices (activated carbon, filters, etc.). However, neither of these methods is suitable for use outside of restaurants. The former requires ductwork and machine mounting, making it complex and requiring consideration of renovations and maintenance. The latter, with its integrated table and purification unit, is bulky and heavy, unsuitable for everyday dining. Therefore, providing a suitable fume purification device for everyday home dining is a pressing issue that needs to be addressed. Summary of the Invention

[0005] According to the technical solution of the fume purification equipment provided by the present invention, a fume purification device is provided that can purify fumes, suitable for daily home dining, without the need to consider ductwork laying and machine mounting during renovation, nor the need to design the fume purification equipment and table as an integrated device.

An activated carbon bag can be understood as a bag containing activated carbon granules. The activated carbon bag is capable of adsorbing and purifying flue gas. By using an activated carbon bag, compared to directly placing activated carbon granules within the first cavity, it is easier for personnel to replace the granules and improves the cleanliness of the first cavity.

[0046] It should be noted that the adsorption element can be a combination of various forms such as activated carbon granules, activated carbon plates, and activated carbon bags, and can be flexibly set according to the actual application scenario.

[0084] In some embodiments, optionally, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fume purification equipment 100 also includes a support plate 122. Specifically, the support plate 122 is disposed within the cavity 111. The support plate 122 is connected to the cavity wall of the cavity 111. Optionally, the support plate 122 is detachably connected to the cavity wall of the cavity 111, facilitating disassembly and assembly by personnel and aiding in maintenance or replacement. Optionally, the support plate 122 and the housing 110 are an integral structure, meaning the support plate 122 is formed by the protrusion of the cavity wall of the cavity 111. This design, compared to post-processing, offers better mechanical properties, higher connection strength, and helps reduce the number of parts, improving assembly efficiency.

[0085] Furthermore, the number of support plates 122 is at least one, that is, there can be one, two or more support plates 122. Considering the support effect, the space occupied, the cost and other factors, the support plates 122 can be flexibly set according to actual needs.

[0086] When there is only one support plate 122, a second air outlet channel 1221 is provided on the support plate 122.

[0087] When there are at least two support plates 122, a second air outlet channel 1221 is provided on the support plate 122, or a second air outlet channel 1221 is formed between at least two support plates 122.

[0088] It should be noted that the support plate 122 can be of any shape, such as having an L-shaped cross-section.

[0089] Further, the cavity 111 includes a first cavity 1111 and a second cavity 1112. One side of the support plate 122 faces the first cavity 1111, and the other side of the support plate 122 faces the second cavity 1112. The second air outlet channel 1221 communicates with the first cavity 1111 and the second cavity 1112. The second air outlet channel 1221 is used to connect the first cavity 1111 and the second cavity 1112. Optionally, the air inlet channel 130 passes through the noise reduction structure 121 and the support plate 122. The fan 140 is disposed in the second cavity 1112. The fan 140 has an air inlet 141 and an air outlet 142. The air inlet 141 of the fan 140 is connected to the air inlet channel 130, and the air outlet 142 of the fan 140 is connected to the second cavity 1112. Optionally, if the purification component 150 is disposed within the cavity 111, the purification component 150 is centrally disposed within the first cavity 1111.

[0090] By setting up the support plate 122, it is beneficial to optimize the internal space layout of the housing 110. In some application scenarios, the purification component 150 can be centrally located in the first cavity 1111 and separated from the fan 140 in the second cavity 1112, which makes it convenient for staff to regularly maintain or replace the purification component 150.

[0091] In some embodiments, the fan 140 is optionally disposed within the second cavity 1112. The fan 140 has an air inlet 141 and an air outlet 142, the air inlet 141 being connected to the air inlet channel 130, and the air outlet 142 being connected to the second cavity 1112.

[0092] The flue gas sequentially passes through the air inlet duct 130, air inlet 141, air outlet 142, second cavity 1112, second air outlet duct 1221, first cavity 1111, and first air outlet duct 171. This design provides a more significant purification effect compared to methods that only use axial fans and filters for flue gas purification. Furthermore, the fume purification device 100 of this invention can be installed on the ground, eliminating the need for desktop space. Optimizing the flue gas flow path further enhances the purification effect.

[0093] In some embodiments, optionally, such as Figure 7 As shown, the purification component 150 includes a gas-liquid separator 152. Specifically, the gas-liquid separator 152 is located within the air inlet channel 130. The gas-liquid separator 152 can separate liquid droplets (water droplets and oil droplets) in the flue gas, improving the purification effect. The working principle of the gas-liquid separator 152 is as follows: when the flue gas passes through the gas-liquid separator 152, the filamentous structure of the gas-liquid separator 152 can adsorb liquid droplets in the flue gas to achieve the purpose of gas-liquid separation.

[0094] In some embodiments, the gas-liquid separator 152 may optionally be a cylindrical, spherical, or mesh structure. This design facilitates replacement of the gas-liquid separator 152 by operators and improves the purification effect on flue gas.

[0095] In some embodiments, optionally, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the purification assembly 150 includes an adsorption element 153. Specifically, the adsorption element 153 is disposed within the cavity 111. Optionally, the adsorption element 153 is disposed within the first cavity 1111. The adsorption element 153 is capable of adsorbing and purifying flue gas.

[0096] Optionally, the adsorption element 153 has a layered structure and multiple through holes. In other words, the adsorption element 153 has a honeycomb structure.

[0097] Optionally, the adsorbent 153 is activated carbon granules. The activated carbon granules are laid in the first cavity 1111 in a layered structure.

[0098] Optionally, the adsorption element 153 is an activated carbon plate. The activated carbon plate is detachably connected to the cavity wall of the first cavity 1111, which facilitates the disassembly and assembly of the activated carbon plate by the operator, and is beneficial for maintenance or replacement. Optionally, the activated carbon plate is detachably connected to the cavity wall of the first cavity 1111 by an insertion method.

[0099] Optionally, the adsorption element 153 is an activated carbon bag. An activated carbon bag can be understood as a bag containing activated carbon granules. The activated carbon bag can adsorb and purify flue gas. By using an activated carbon bag, compared to directly placing activated carbon granules in the first chamber 1111, it is easier for staff to replace the granules and helps improve the cleanliness of the first chamber 1111.

[0100] It should be noted that the adsorption element 153 can be a combination of various forms such as activated carbon granules, activated carbon plates, and activated carbon bags, and can be flexibly set according to the actual application scenario.

[0101] In some embodiments, optionally, such as Figure 7 As shown, the fan 140 is connected to the air inlet duct 130 via a guide ring 181. By setting the guide ring 181, the airflow can be guided, allowing the flue gas in the air inlet duct to smoothly enter the air inlet 141 of the fan 140.

[0102] It should be noted that when the support plate 122 and the housing 110 are integrated, the flow guide ring 181 and the purification component 150 located in the cavity 111 are also integrated.
