[0002] Industrial smoke typically consists of oil fume and oil mist. Oil fume refers to the fumes produced by the oil layer adhering to the workpiece surface under high temperature. Oil mist, on the other hand, refers to the mixture of mist and smoke produced by the splashing, high-speed rotation, and high-temperature volatilization of lubricating oil (cutting oil) during machining. These oil fume and oil mist permeate the workshop environment, causing harm to employee health and shortening the service life of production equipment. Therefore, purification of workshop smoke is imperative.

[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] Example like Figure 1 、 2 、3 as shown ( Figure 3 The middle arrow indicates the direction of oil fume flow). The novel electrostatic oil fume purification device of this embodiment includes a chassis 1 and multiple groups of electrostatic purification components 2. The chassis 1 is provided with an oil fume inlet (indicated by D in the figure) at the lower part and an oil fume outlet at the top. A serpentine purification channel extending from bottom to top is defined inside the chassis 1 between the oil fume inlet and the oil fume outlet. Multiple groups of the electrostatic purification components 2 are sequentially spaced (sequentially spaced according to the direction of oil fume flow) in the purification channel, and an auxiliary smoke exhauster 3 is provided at the oil fume outlet.

[0021] When the new electrostatic fume purification device of this embodiment is in use, fume enters through the fume inlet and flows upward through the purification channel. During this process, the fume passes through the electrostatic purification component 2, where the high-voltage electrostatic field charges the fume particles. The charged fume particles are then adsorbed and processed under the action of the electric field, thereby purifying the fume. The purification effect can also be optimized by adjusting the electric field intensity and airflow velocity. The purification channel adopts a serpentine (also called an "S" shape) distribution pattern, which effectively distributes the airflow and evenly distributes the fume within the electric field, resulting in a more effective purification process. Furthermore, the purification channel runs from bottom to top (i.e., extends longitudinally), allowing the entire device to be arranged longitudinally, improving the large footprint of traditional horizontal devices.

[0022] Of course, in this embodiment, the purification channel may adopt a stair-like inclined channel extending upward alternately.

[0023] In this embodiment, a plurality of wheels can be installed at the bottom of the chassis 1 to facilitate the overall movement and transportation.

[0024] As a preferred embodiment, a plurality of horizontally distributed oil collecting pans 11 are provided on the side walls on both sides of the interior of the chassis 1 at intervals up and down, and the oil collecting pans 11 extend toward the opposite side walls respectively, and the two ends of each of the oil collecting pans 11 extend to connect with the side walls on both sides of the chassis 1 respectively, and the purification channel is defined between the plurality of oil collecting pans 11 and the side walls of the chassis 1, and at least one group of the electrostatic purification components 2 is provided between adjacent oil collecting pans 11.

[0025] In the above embodiment, adjacent oil collecting pans 11 are distributed on the opposite side walls of the chassis 1, and the two are staggered with each other, thus forming a serpentine (or S-shaped) purification channel. When the oil smoke passes through the purification channel, it can be effectively purified by the electrostatic purification component 2, and the oil mist particles adsorbed and collected will be collected in the flow channel oil collecting pan 11, which is conducive to subsequent processing.

[0026] In this embodiment, both ends of the oil collecting pan 11 are connected to both end side walls of the chassis 1 , and the oil collecting pan 11 is assembled using bolts or other detachable assembly methods to facilitate subsequent maintenance.

[0027] As a preferred embodiment, the bottom of the oil collecting pan 11 located above is connected to the interior of the adjacent oil collecting pan 11 below through a pipeline, and an oil leakage hole is provided at the bottom of the lowest oil collecting pan 11, and an oil collecting bin 12 is defined below the oil collecting pan 11.

[0028] In the above embodiment, the upper oil collecting pan 11 is connected to the lower oil collecting pan 11 through a pipeline, so that the collected oil is finally gathered in the lowest oil collecting pan 11, and then enters the oil collecting bin 12 at the bottom of the chassis 1 through the oil leakage hole. The oil collection route is reasonable and centralized treatment is more convenient.

[0029] As a preferred embodiment, a smoke inlet chamber 13 is defined on one side of the oil collecting bin 12 by a partition and the side wall thereof, an opening communicating with the smoke inlet chamber 13 is provided at the bottom of the lowest oil collecting tray 11, and an oil fume inlet communicating with the smoke inlet chamber 13 is provided at the lower portion of the side wall of one side of the chassis 1.

[0030] In the above embodiment, the oil collection bin 12 is divided into two parts, one part is the smoke inlet chamber 13 connected to the smoke inlet for introducing the smoke, and the other part is a larger oil collection area. After the smoke enters the smoke inlet chamber 13, it passes through the opening at the top and enters a purification channel defined on the upper part of the lowest oil collecting tray 11, and enters the subsequent purification treatment process. The path distribution is reasonable and clear.

[0031] As a preferred embodiment, filters 14 are respectively provided at both ends of the electrostatic purification assembly 2 between the adjacent oil collecting pans 11 .

[0032] In the above embodiment, purely mechanical filters 14 are installed at both ends of each layer of electrostatic purification assembly 2 (i.e., upstream and downstream of the oil smoke flow direction), effectively improving the filtration effect. Overall, the dual effects of mechanical and electrostatic purification are adopted, resulting in high and long-lasting filtration efficiency.

[0033] In this embodiment, mounting grooves are provided between the two sides of adjacent oil collecting pans 11, and the filter screen 14 is detachably installed in the mounting grooves (specifically, the upper and lower ends of the filter screen 14 are respectively embedded in the mounting grooves on the sides of the adjacent oil collecting pans 11 that are close to each other).

[0034] As a preferred embodiment, Figure 7 As shown, the electrostatic purification component 2 includes an outer frame 21, one side of the inner part of the outer frame 21 is set as a high-voltage area, and the other side of the inner part is set as a low-voltage area. A row of first grounding metal plates 211 distributed vertically and parallel to each other are provided in the high-voltage area, and a discharge wire 212 is provided across (wherein, across refers to the direction perpendicular to the multiple first grounding metal plates 211) above the first grounding metal plates 211. A row of conductive plates 213 and second grounding metal plates 214 distributed vertically and parallel to each other are provided in the low-voltage area. There are multiple conductive plates 213 and second grounding metal plates 214 respectively, and they are staggered and spaced apart. The multiple conductive plates 213 are commonly connected to a conductive member 215.

[0035] In the above embodiment, the discharge wire 212 and the conductive member 215 are each connected to a power source. A high-voltage electrostatic field is generated between the discharge wire 212 and the first grounded metal plate 211, charging the passing oil fume particles. These charged oil fume particles then pass through the low-voltage electric field formed between the conductive plate 213 and the second grounded metal plate 214. The charged oil fume particles are then deflected by the Coulomb force within the electric field and attracted to the second grounded metal plate 214, effectively purifying the oil fume. As the oil fume particles accumulate on the second grounded metal plate 214, they flow downward under gravity along the second grounded metal plate 214 and fall into the oil collection pan 11 below, resulting in a highly effective purification process.

[0036] It should be noted that in this embodiment, the discharge wire 212 (equivalent to the positive electrode) is connected to a high voltage (generally between 12,000V and 14,000V) and carries a positive charge. The first grounded metal plate 211 (equivalent to the negative electrode) is grounded and has a zero potential. This creates a potential difference between the two. According to the basic principles of electric fields, the electric field lines will be directed from the high-voltage discharge wire 212 to the grounded first grounded metal plate 211, thus forming a high-voltage electrostatic field. Furthermore, the conductive plate 213 (equivalent to the positive electrode) is connected to a high voltage (generally between 6,000V and 7,000V, lower than the high voltage connected to the discharge wire 212) and carries a positive charge. The second grounded metal plate 214 (equivalent to the negative electrode) is grounded and has a zero potential. This creates a potential difference between the two. According to the basic principles of electric fields, the electric field lines will be directed from the high-voltage conductive plate 213 to the grounded first grounded metal plate 214, thus forming a low-voltage electrostatic field.

[0037] In this embodiment, the discharge filament 212 is made of tungsten and mounted on a connecting rod that spans across multiple first grounded metal plates 211. It features long life and high temperature resistance, high purification efficiency, and a low discharge rate. This prevents excessively high discharge voltage from causing persistent degradation of the recovered oil, allowing for secondary use of the recovered oil and providing a small amount of ozone for indoor air disinfection. The outer frame 21 is fabricated from aviation-grade aluminum sheet, offering high structural strength and lightweight. The conductive member 215 is a conductive rod that extends transversely through each conductive plate 213 and also through a corresponding through-hole in each second grounded metal plate 214 (without contact). The multiple second grounded metal plates 214 are connected by a transversely extending rod that extends through a corresponding through-hole in each conductive plate 213 (without contact).

[0038] As a preferred embodiment, adjacent oil collecting pans 11 are provided with guide rail grooves for slidingly cooperating with the electrostatic purification components 2 on their respective sides, and the electrostatic purification components 2 are arranged between the upper and lower guide rail grooves. The side wall at any end of the chassis 1 is provided with an inspection port for pulling out or pushing in the electrostatic purification components 2 along the guide rail grooves, and the inspection port is provided with a door (denoted by A in the figure) that can be opened or closed. The other end of the chassis 1 is provided with contact terminals corresponding one-to-one to the discharge wire 212 and the conductive member 215, and one end of the electrostatic purification component 2 is provided with conductive contacts (denoted by e in the figure) respectively connected to the discharge wire 212 and the conductive member 215. The other end of the chassis 1 is provided with contact terminals corresponding one-to-one to the conductive contacts, and the conductive contacts are in contact with or separated from the corresponding contact terminals.

[0039] In the above embodiment, the combination of the structural coordination of the electrostatic purification component 2 and the guide rail groove + the contact coordination of the conductive contact piece and the contact terminal enables the electrostatic purification component 2 to be quickly pulled out or pushed in from the inspection port at one end of the chassis 1, which is very beneficial to the inspection and maintenance of the electrostatic purification component 2.

[0040] In this embodiment, an electrical box (control cabinet, indicated by B in the figure) is provided on the outer surface of the chassis 1, and the conductive contacts inside the chassis 1 are connected to the electrical box, which controls the power-on state and parameter state of the relevant electrical components in the electrostatic field.

[0041] In this embodiment, the conductive contact can be a conventional spring conductive sheet. The guide track groove can be a plurality of T-shaped beams spaced laterally and arranged in parallel. Two of the T-shaped beams are fixed to the bottom wall of the oil collecting pan 11. The corresponding ends of the electrostatic purification assembly 2 are slidably embedded between the two T-shaped beams and can be pulled out or pushed in along the T-shaped beams. At the same time, it will not affect the oil from dripping from between the two T-shaped beams into the oil collecting pan 11 below.

[0042] In this embodiment, a support top plate 15 is provided on the upper portion of the inner sidewall of the chassis 1. The auxiliary smoke exhauster 3 is mounted on the upper end of the support top plate 15 via a bracket. A smoke exhaust port 151 is provided on the support top plate 15 at a position corresponding to the lower portion of the auxiliary smoke exhauster 3. The auxiliary smoke exhauster 3 is located below the oil smoke outlet. The design of the support top plate 15 facilitates the assembly of the auxiliary smoke exhauster 3, and the design of the smoke exhaust port 151 facilitates the centralized discharge of treated oil smoke.

[0043] As a preferred embodiment, Figure 3 、 4 As shown in , 5 , it also includes a centrifugal oil mist separator 4, and the outlet of the centrifugal oil mist separator 4 is connected and communicated with the oil fume inlet.

[0044] In the above embodiment, before the oil smoke enters the chassis 1 for treatment, it is separated and filtered by the centrifugal oil mist separator 4. Specifically, after the oil smoke enters, the large oil smoke particles are separated and thrown out under the action of centrifugal force, and the gas containing small oil smoke particles then enters the subsequent chassis 1 for treatment. The addition of this dynamic centrifugal separation can effectively reduce the load of the back-end electrostatic treatment, improve the purification effect, enhance stability, and extend the maintenance cycle.

[0045] As a preferred embodiment, Figure 3 、 6As shown in Figures 7 and 8, the centrifugal oil mist separator 4 includes a separation box 41, which has a smoke inlet on one side and a smoke outlet on the other side. The smoke outlet is connected to and communicates with the oil smoke inlet. A movable port is provided on the top of the separation box 41, in which a centrifugal separation assembly 42 extending into the interior of the separation box 41 is inserted. The centrifugal separation assembly 42 includes a support frame 421, an outer disc 422, a separation disc 423 and a rotary drive device 424. The outer disc 422 is annular and is installed in the support frame 421. The outer edge diameter of one end of the outer disc 422 is larger than the diameter of the other end. The separation disc 423 includes a central disc and separation strips distributed around the central disc in a spiral shape. The separation strips are connected with a plurality of concentrically arranged support rings at intervals from the center to the outer edge of the separation disc 423. The rotary drive device 424 is installed in the support frame 421 and is coaxially connected to the central disc of the separation disc 423. An oil collecting chamber is formed at the lower part of the inner cavity of the separation box 41.

[0046] In the above embodiment, the rotary drive device 424 drives the separation disc 423 to rotate at high speed. When the incoming oil smoke passes through the gaps between the separation bars on the separation disc 423, a centrifugal vortex is formed, causing large oil smoke particles to be thrown to the inner side of the outer disc 422 at the outer edge. The particles flow downward along the outer disc 422 and fall into the separation box 41. This effectively separates the oil smoke at the front end, removes large oil smoke particles, and significantly reduces the load of subsequent purification.

[0047] In this embodiment, the rotation drive device 424 uses an explosion-proof motor of an adapted model.

[0048] In this embodiment, the auxiliary smoke exhaust device 3 is a smoke exhaust fan, and a filter (indicated by C in the figure) is installed in the oil smoke outlet. This filter not only prevents foreign matter from entering the chassis 1, but also filters the oil smoke to a certain extent during exhaust. The motor of the smoke exhaust fan is an explosion-proof motor.
