[0020] Example

[0021] Please see Figure 1-4A multiphase flow solid-liquid separation and oil mist particulate matter precision filtration device includes a cyclone separator 1, a collection tank 2 is provided on the lower side of the cyclone separator 1, an exhaust port 9 of the cyclone separator 1 is connected to a conveying pipe 3, a processing box 4 is provided on one side of the cyclone separator 1, the processing box 4 is divided into a first processing chamber 6 and a second processing chamber 7 by a partition 5, a collection trough 8 is provided on the lower side of the first processing chamber 6, an exhaust port 9 is provided inside the collection trough 8, and the lower side of the exhaust port 9 extends from the lower side of the processing box 4 and is connected to one side of the conveying pipe 3.

[0022] A diversion assembly is provided on the upper side of the exhaust port 9, a wire mesh demister 10 is provided on the upper side of the diversion assembly, a through hole is provided on the upper side of the partition plate 5, an ionization frame 11 is provided inside the second treatment box 4, a dust collection plate 12 is arranged alternately on one side of the ionization frame 11, and a movable plate 13 is provided on the front side of the treatment box 4.

[0023] The diversion frame includes a rhombus-shaped block 14 disposed on the upper side of the exhaust port 9. The lower side of the rhombus-shaped block 14 is connected to the upper side of the exhaust port 9 through a support rod. A first guide groove 15 is provided on both sides of the upper side of the rhombus-shaped block 14, and guide blocks 16 are evenly disposed on both sides of the rhombus-shaped block 14.

[0024] It should be noted that during use, the multiphase flow first enters the cyclone separator 1, and centrifugal force can separate most of the solid particles and part of the liquid in the multiphase flow. Then, the separated solid particles and oil mist liquid will flow into the collection tank 2 for collection under the action of gravity. Then, the air with the remaining oil mist will be discharged through the exhaust port 9 of the cyclone separator 1 and transported through the conveying pipe 3. Finally, it will be discharged into the first processing chamber 6 through the exhaust port 9. At this time, the gas will be sprayed on the lower side of the rhomboid block 14 and perform a diversion operation, so that the gas can impact both sides of the wire mesh demister 10, preventing the gas from only acting on the middle part of the wire mesh demister 10 and affecting the demisting effect of the wire mesh demister 10. The wire mesh demister 10 can adsorb large oil mist particles in the gas. Then, the mist droplets will agglomerate and coalesce into large droplets, and drip into the collection tank 8 for collection under the action of gravity.

[0025] The diamond-shaped block 14 can block the dripping droplets, preventing them from entering the exhaust port 9 and causing blockage. When the droplets fall, they enter the first guide channel 15, then flow through the second guide channel 17, and finally flow into the collection tank 8 through the guide block 16 for collection. The gas after being processed by the wire mesh demister 10 will enter the second processing chamber 7 through the through hole.

[0026] The ionization frame 11, high-voltage power supply 18, and dust collection plate 12 work together. The ionization frame 11 is composed of an insulating frame and a corona wire. The insulating frame and corona wire, together with the high-voltage power supply 18, can form a high-voltage electric field. The high-voltage electric field charges the remaining small oil mist particles and adsorbs them to the dust collection plate 12 through the electric field force. Finally, the remaining oil mist particles in the air can be removed, thereby achieving the effect of multiphase flow solid-liquid separation and precise filtration of oil mist particles.

[0027] After the above operations are completed, the movable plate 13 on the front side of the processing box 4 can be removed, and maintenance and cleaning operations can be performed on the components inside the first processing chamber 6 and the second processing chamber 7.

[0028] The collection tank 2 has a first outlet 19 on its lower side, and the processing box 4 has a second outlet 20 on its lower side that communicates with the collection tank 8. The first outlet 19 and the second outlet 20 can discharge solid particles inside the collection tank 2 and oil mist droplets inside the collection tank 8.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
