the working principle is as follows: when the oil smoke waste gas filtering device is used, the air inlet 21 of the waste gas purifying mechanism 2 is connected with an oil smoke waste gas pipeline, oil smoke waste gas passes through the air inlet 21, the air inlet flow speed is reduced through the reducing diameter 22, the oil smoke waste gas enters the waste gas purifying mechanism 2, the oil smoke waste gas vertically passes through the filter element 36, the oil smoke in the oil smoke waste gas is intercepted by the filter element 36 and is left on the filter element 36, and the oil smoke waste gas is filtered;
meanwhile, the driving motor 34 synchronously keeps rotating, the driving motor 34 drives the central shaft 35 to rotate, the filter element 36 connected to the outer side of the central shaft 35 synchronously keeps rotating, the rotating speed is one hour and one circle, due to the rotation, the filter element 36 rotates, when the upper part is purified, the filter element 36 containing oil smoke rotates to the lower part and is then soaked in the flushing liquid 32, the main component of the flushing liquid 32 is alkaline liquid with the pH value not lower than 9, so that the oil smoke components are dissolved and eliminated, and the purification purpose is achieved;
meanwhile, due to purification of the filter element 36, some particles which are insoluble in the washing liquid 32 exist on the surface, the filter element particle scrubbing mechanism 4 starts to work, the drive disc 46 inside the filter element particle scrubbing mechanism starts to work, the eccentric block 47 arranged on the drive disc 46 starts to rotate synchronously, the eccentric block 47 drives the second mounting sleeve 45 to rotate synchronously, the moving rod 48 connected to the bottom end of the second mounting sleeve 45 moves synchronously, the cleaning bristles 49 connected to the outer side of the moving rod 48 scrub the filter element 36, the particles which are insoluble in the washing liquid 32 on the surface of the filter element 36 are scrubbed, adhesion of the particles is avoided, and the purification performance of the filter element 36 is influenced;
meanwhile, the pH value monitor 33 and the medicine adding mechanism 5 form a medicine adding system matched with the device, the pH value monitor 33 monitors the pH value of the washing liquid 32 in real time, when the pH value of the washing liquid 32 is less than 9, a central processing unit in the system starts to work, an alkali liquid adding pump 51 is controlled to start to work, and 30% NaOH solution stored in an alkali liquid storage tank 52 is added into the washing liquid 32 through a diversion pipeline 53 and a medicine adding pipe 54; when NaOH solution is continuously added into the washing liquid 32, the pH value monitoring meter 33 synchronously keeps monitoring, when the pH value of the washing liquid 32 reaches 12, the central processing unit works to control the alkali liquid adding pump 51 to stop working, so that the pH value in the washing liquid 32 is ensured to be constant;
the water supply and drainage mechanism 6 matched with the device can periodically replace water, the water replacement period can be artificially set to 14 days, and the water replacement period can also be specifically determined according to the concentration of waste gas; the height of the flushing liquid 32 is monitored through the magnetic turning plate liquid level meter 7, when the flushing liquid 32 reaches a high liquid level, the plant water feeder 61 stops adding water, and when the flushing liquid is lower than the low liquid level, the plant water feeder 61 automatically supplements water through the water feeding pipeline 62.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
