Description

Technical Field

[0001] This utility model relates to an oil fume purification device, and more particularly to an oil mist and water mist purification device used for intercepting and purifying oil mist and water mist. Background Technology

[0002] With the development of industry and other sectors, energy consumption has gradually increased, leading to a corresponding increase in emissions of industrial oil mist and water mist, which easily cause air pollutants. These emissions include oil mist and water mist generated by machining equipment, and they often involve the release of significant amounts of heat. If these oil and water mists are not purified, they will cause varying degrees of health pollution to workshops, machining sites, and personnel involved in machining, as well as various environmental hazards. While some oil fume purification devices can intercept and purify these emissions, these solutions only consider the interception and purification process and fail to recover and utilize the heat generated by the emissions during the process. This results in the heat being directly emitted, leading to low heat circulation efficiency and high energy consumption, which is detrimental to the current national environmental protection development goals. Furthermore, during the process of intercepting and purifying oil and water fumes, the oil-slinging disc separates the purified gas from the intercepted oil and water droplets, ultimately collecting and discharging them. The discharge of these droplets is closely related to their temperature; lower temperatures result in lower fluidity, which is detrimental to improving the discharge efficiency of the collected droplets. Additionally, during prolonged use, especially at lower temperatures, oil residue can easily accumulate on the spokes of the oil-slinging disc, requiring regular disassembly and cleaning, which increases the workload of cleaning the spokes.

[0003] Patent No. ZL202022934088.8, published on August 10, 2021, discloses a centrifugal oil mist purifier, comprising a first body and a second body, fixedly connected. An air inlet pipe is fixedly opened at the top of the second body, an exhaust screen is fixedly connected to the surface of the first body, and a filter screen and an interceptor plate are fixedly connected inside the second body, with the interceptor plate located below the filter screen. An inner cavity is fixedly opened inside the second body. When oil mist enters the processing chamber, it is heated by a heating chamber. Simultaneously, when the oil mist forms a liquid phase on the surface of the interceptor screen, the heated liquid phase is easily transported, and the opening in the center of the interceptor screen facilitates the flow of the liquid phase. However, this design also suffers from drawbacks such as the lack of energy recovery considerations, resulting in low heat circulation efficiency and high energy consumption and emissions, which is detrimental to the current national requirements for environmental protection and development, and also hinders the improvement of the self-cleaning efficiency of the oil-slinging plate. Utility Model Content

[0004] This utility model addresses the shortcomings of existing oil fume purification devices, such as the lack of energy recovery considerations, resulting in low heat circulation efficiency and high energy consumption and emissions. This is detrimental to the current national requirements for environmental protection and development. The invention provides an oil fume and water mist interception device that can both intercept and purify industrial oil mist and water mist waste gases, and recover the heat generated by these waste gases themselves. This improves the heat circulation efficiency of the equipment, reduces energy consumption and emissions, better meets the national requirements for environmental protection and development, and enhances the self-cleaning efficiency of the oil slinger.

[0005] The specific technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an oil mist and water mist interception device, including a chassis and a pre-purification exhaust gas inlet port and a purified gas outlet port, characterized in that: it also includes several oil-slinging discs, the chassis is provided with several oil-slinging discs, a movable door and a gas internal circulation channel, and the exhaust gas before purification is purified by several oil-slinging discs and then led out from the gas outlet port. Several oil-slinging discs are arranged sequentially in the chassis to form a multi-stage oil-slinging disc purification mechanism. The movable door is located on the side of the gas outlet port, and the gas internal circulation channel is located in the area outside the several oil-slinging discs. The upper end of the gas internal circulation channel is provided with a movable door. When the movable door is opened, the upper end of the gas internal circulation channel is connected to the outside of the gas outlet port, and the lower end of the gas internal circulation channel is connected to the inside of the exhaust gas inlet port and the area outside the exhaust gas inlet of the first-stage oil-slinging disc. There is a through-connecting channel between the upper end and the lower end of the gas internal circulation channel. When the movable door is opened, the internal gas circulation channel connects the inner side of the exhaust gas inlet port and the outer side of the exhaust gas outlet port, forming a heat circulation channel where the purified gas circulates from the outer side of the exhaust gas outlet port to the inlet end of the first oil slinger plate inside the exhaust gas inlet port. This not only intercepts and purifies industrial oil mist and water mist, but also recovers the heat generated by the industrial oil mist and water mist themselves, improving the equipment's heat circulation efficiency and reducing energy consumption and emissions. Furthermore, the heat recovered from the purified gas circulating through the internal gas circulation channel to the oil slinger plate improves the fluidity and discharge efficiency of the droplets collected by the oil slinger plate, while also increasing the overall temperature of the oil slinger spokes. This helps prevent oil and water mist from remaining on the oil slinger spokes due to low temperatures, improving the cleanliness of the oil slinger spokes. It also improves the temperature maintenance of the collected droplets after the oil slinger plate intercepts and purifies the oil mist, preventing the collected droplets from cooling and condensing, which is detrimental to discharge. This improves the self-cleaning efficiency of the oil slinger plate and better meets the national needs for environmental protection.

[0006] Preferably, the upper end of the gas internal circulation channel is provided with a door installation and connection window, and the door installation and connection window is provided with a movable door. The opening or closing of the movable door is controlled electrically and / or manually. This improves the simplicity, convenience, and effectiveness of the movable door installation, connection, opening, and closing operations.

[0007] Preferably, the oil-slinging discs are arranged in a configuration of 2 to 4 discs. This improves the flexibility, reliability, and effectiveness of oil mist and water mist interception and purification.

[0008] Preferably, the plurality of oil-slinging discs are arranged vertically from bottom to top, with the gas outlet located directly above the uppermost oil-slinging disc and the exhaust gas inlet located directly below the lowermost oil-slinging disc, forming a vertical upward airflow purification treatment device for oil and water mist. This improves the efficiency of the internal heat circulation of the hot gas passing through the gas internal circulation channel as it automatically rises in the multi-stage oil-slinging discs.

[0009] Preferably, the chassis is provided with several layers of horizontal baffles. Each layer of horizontal baffles is used to install and connect the motor and / or the oil slinger. The installation and connection structure between each layer of horizontal baffles and the chassis adopts a drawer-type pull-out sliding connection structure. This improves the ease, convenience, flexibility, and effectiveness of installation, connection, disassembly, and maintenance between the horizontal baffles and the chassis.

[0010] Preferably, the chassis is provided with several layers of horizontal baffles, wherein the motor and the oil slinger body constituting the oil slinger are respectively mounted on two adjacent layers of horizontal baffles, and the installation connection structure between each layer of horizontal baffle and the chassis adopts a drawer-type pull-out connection structure. This improves the ease, convenience, flexibility, and effectiveness of installation, connection, disassembly, and maintenance between the horizontal baffles and the chassis.

[0011] Preferably, when the transverse baffle is used as a motor connecting baffle for mounting and connecting a motor, the motor connecting baffle has a plurality of baffle through holes arranged in a ring shape, with each baffle through hole having a fan-shaped structure. This improves the smoothness, reliability, and effectiveness of gas flow.

[0012] Preferably, the transverse baffle adopts a two-part independent baffle structure, with an inner part and an outer part. The inner part is located inside the device housing, and the outer part is located outside the device housing. Each of the two independent baffles has an installation slot on its adjacent side, which is used to install and connect the motor or the boom plate. The installation connection between each transverse baffle and the device housing is a drawer-type pull-out sliding connection. The installation connection between the two baffles and the housing involves first installing the inner part, then the motor or boom plate, and finally the outer part. This improves the ease, convenience, flexibility, and effectiveness of installation, connection, disassembly, and maintenance between the transverse baffle and the housing, and between the transverse baffle and the motor or boom plate.

[0013] Preferably, the top of the chassis is equipped with a chassis cover, the chassis cover has an external exhaust window, and the inner side of the external exhaust window has a movable cover plate; the side of the chassis is equipped with a chassis side door, and the chassis side door has an operation switch box and an operation switch panel, the operation switch panel has an electric switch or manual switch for the movable door. This improves the simplicity and effectiveness of the purified gas discharge, improves the airflow guidance effectiveness of the gas internal circulation, and improves the simplicity, convenience, flexibility and effectiveness of opening or closing the movable door. When the external exhaust window (exhaust port) is closed, a closed-loop internal circulation channel is formed. The lower end of the gas internal circulation channel is connected to the exhaust gas chamber, which pressurizes the exhaust gas chamber and helps to push the exhaust gas to the first oil slinger inlet end inside the exhaust gas inlet port. When the external exhaust window is closed, a closed-loop circulation channel is formed, which can increase the exhaust gas processing capacity. Due to the flow of cutting fluid, the temperature in the exhaust gas chamber can be maintained within the set threshold.

[0014] Preferably, the plurality of transverse baffles comprises a set of transverse baffles consisting of a motor plate, a No. 1 oil slinger baffle, a No. 2 oil slinger baffle, and a bearing seat plate. Each set of transverse baffles is used to install two synchronously rotating oil slingers driven and controlled by a motor and a rotating bearing. The rotating bearing and the two synchronously rotating oil slingers are connected and mounted on the same motor drive output shaft. This improves the driving, use, installation, stability, reliability, simplicity, and effectiveness of the oil slingers.

[0015] The beneficial effects of this invention are: it can intercept and purify industrial oil mist and water mist, and recover the heat generated by the industrial oil mist and water mist itself, improving the heat circulation efficiency of the equipment and reducing energy consumption and emissions; furthermore, when the heat of the purified gas recovered through the gas internal circulation channel flows to the oil slinger, it improves the fluidity and discharge efficiency of the droplets collected by the oil slinger, and also increases the overall temperature of the oil slinger spokes, better preventing oil and water mist from remaining on the oil slinger spokes due to low temperature, thus improving the cleanliness of the oil slinger spokes. It also improves the temperature maintenance of the collected droplets after the oil mist interception and purification by the circulating airflow, avoiding the defects of cooling and condensation of the collected droplets after purification, thus improving the self-cleaning efficiency of the oil slinger and better meeting the national needs for environmental protection. To a certain extent, the gas internal circulation channel forms a siphon effect on the waste gas, improving the reliability and effectiveness of the oil mist and water mist interception and purification device when the waste gas is introduced into the system. When the external exhaust window (exhaust port) is closed, a closed-loop internal circulation channel is formed. The lower end of the internal gas circulation channel is connected to the exhaust gas chamber, which pressurizes the exhaust gas chamber and helps to push the exhaust gas to the first oil slinger inlet end inside the exhaust gas inlet port. When the external exhaust window is closed, a closed-loop circulation channel is formed, which can increase the exhaust gas processing capacity. Due to the flow of cutting fluid, the temperature in the exhaust gas chamber can be maintained within the set threshold.
