DETAILED DESCRIPTION

[0027] A flue gas purification method, the method comprising the following steps:

[0028] S1: introducing the flue gas into the treatment device;

[0029] S2: The flue gas is filtered and discharged through the activated carbon in the treatment device;

[0030] S3: moving smoke stains generated when the oil smoke and fume circulate in the treatment device out of the oil smoke and fume circulation position;

[0031] S4: cleaning and scraping the smoke stains removed from S3 by a processing device;

[0032] S5: While S4 is being performed, the cleaning and scraping position is flushed and cleaned synchronously by the processing device.

[0033] This part is based on Figure 2-5 The working process expressed in 10 and 11 is: in order to improve the efficiency of purifying the oil fume by physical methods when it is discharged, when in use, the bottom of the connecting pipe 101 is installed at the exhaust port of the oil fume, and then a top frame 102 is fixedly connected to the upper side of the connecting pipe 101 by welding, so that the top frame 102 is aligned with the position of the oil fume exhaust on the upper side of the connecting pipe 101, and then in order to maximize the efficiency of the oil fume exhaust after passing through the top frame 102 and being filtered, the motor Ⅰ105 located on the upper side of the top frame 102 is driven to rotate the rotating rod Ⅰ103 fixedly connected to the output shaft of the motor Ⅰ105 by a coupling, and synchronously make the multiple fan blades 104 located at the bottom of the rotating rod Ⅰ103 fixedly connected by welding perform a circular motion to form an upward wind direction, so as to maximize the efficiency of the oil fume exhaust after passing through the top frame 102 and being filtered. A cross grid frame 201 is slidably connected to the lower side of the top frame 102, and an adsorption frame 202 is fixedly connected to the upper side of the cross grid frame 201 by bolts. An appropriate amount of activated carbon is stored in the adsorption frame 202 for filtering and purifying the oil smoke and flue gas passing through the top frame 102, so as to improve the efficiency of physical methods for purifying the oil smoke and flue gas when it is discharged, and further make the length of the cross grid frame 201 and the adsorption frame 202 longer than that of the top frame 102. Therefore, half of the cross grid frame 201 and the adsorption frame 202 are on the outside of the top frame 102 where the oil smoke and flue gas circulates. When the cross grid frame 201 and the adsorption frame 202 are on one side inside the top frame 102 and need to be cleaned and the activated carbon in the adsorption frame 202 needs to be replaced after long-term use, it is only necessary to slide the cross grid frame 201 to change the circulation alignment position, thereby improving the service life of the cross grid frame 201 and the adsorption frame 202, and further maintaining the stability of the activated carbon in the adsorption frame 202 for flue gas purification.

[0034] This part is based on Figure 2-5The working process expressed in 10 and 11 is: multiple circular holes are evenly processed on the upper and lower sides of the adsorption frame 202 to facilitate the oil smoke and flue gas to pass through the activated carbon in the adsorption frame 202 with maximum efficiency and be filtered and purified.

For the horizontal grid frame 201 that slides out on one side, any motor II 306 is driven accordingly, so that the bottom of the sliding frame 302 is fixedly connected to the movable end of the electric push rod 305 through a flange, and the fixed end of the electric push rod 305 is fixedly connected to the front side of the bottom of the square frame 301 through a flange, driving the electric push rod 305 to rotate any cleaning seat 304, clean the smoke stains on the bottom horizontal bars of the horizontal grid frame 201 that slides out on any side, and further improve the service life of the overall device.
