The suction area of the side suction port 11 is larger than that of the top suction port 93. The invention realizes the adjustment of wind power by controlling the air suction areas of different air suction openings, so that the wind power is larger and the oil smoke is less dissipated although the side air suction opening is far away from the fan.

And a screen plate 91 is arranged at the position of the top air suction opening 93. The screen plate can intercept greasy dirt on one hand, and on the other hand, the size of the suction force of the fixed suction opening can be controlled by controlling the mesh size on the screen plate.

The soot gas is dissociated when passing through the cathode tube 511.

The height of the crest of the external thread 513 from the root is at least 2mm, preferably 2 mm. Too low a distance between the tooth tip and the tooth root of the external thread 513 may result in a non-protruding discharge portion and insufficient electrostatic strength; too great a height of the crests of the external threads 513 from the roots results in difficulty in machining and no significant increase in electrostatic strength.

The thread pitch of the external thread 513 is 0.5-2 times of the height of the thread tip from the thread root. The thread pitch of the external thread 513 cannot be too small, which causes mutual interference of discharge and insufficient uniformity of static electricity, and the fact proves that when the thread pitch of the external thread 513 is 0.5-2 times of the height of the thread tip from the tooth root, the static electricity is uniform.

In the high-voltage electrostatic module, the cathode tubes 511 can be tightly attached to each other to reduce the space without generating static electricity, and when the device is in practical use, the space between the outsides of the different cathode tubes 511 can be sealed at the end part, so that the oil smoke waste gas is prevented from entering the space without generating static electricity, and the oil smoke waste gas is ensured to pass through a high-voltage electrostatic field. By adopting the high-voltage electrostatic module, the shape between the anode and the cathode is more uniform, and the oil smoke and the waste gas are divided into the spiral tubular electric field structures 51 one by one, so that the required voltage is lower while the purification effect is ensured.

The ring shape is at least more than 3 rings, and can be set according to the requirement.
