the multi-scale particles (7) comprise an air dissipation core (71) and a plurality of overlapped scales (72) arranged outside the air dissipation core (71), and the plurality of overlapped scales (72) are mutually staggered and laminated;
the air-purifying core (71) is made of water-soluble aerated material, and the overlapped scales (72) are made of super-absorbent fiber material.
2. A double variable extension fume filtration device according to claim 1 wherein: the using method comprises the following steps:
s1, firstly, introducing waste gas into the equipment through the gas inlet pipe (31), filtering the waste gas in the equipment body (1) through the lower gas filtering plate (51), the extension filtering layer (6) and the upper gas filtering plate (52) in sequence, and discharging the waste gas out of the equipment through the gas outlet pipe (32);
s2, after the exhaust gas is filtered for a long time, the lower air filter plate (51), the extension filter layer (6) and the upper air filter plate (52) are blocked, the air inlet pipe (31) and the cleaning outlet pipe (42) are closed firstly;
s3, supplementing multi-scale particles (7) into the equipment body (1) through the cleaning inlet pipe (41), and inflating the equipment body (1) through the cleaning inlet pipe (41) until the extension filter layer (6) is extended and spread;
s4, introducing water into the device through the cleaning inlet pipe (41), closing the cleaning inlet pipe (41) after a period of time, and controlling the extended filter layer (6) to rotate through the electric rotating shaft;
s5, rotating for 5-10 minutes, standing for 30-60min, discharging gas of the multi-scale particles (7) under the action of water, disintegrating, impact adsorbing impurities filtered in pores of the extension filter layer (6), the lower air filter plate (51) and the upper air filter plate (52), finally opening a cleaning outlet pipe (42) to discharge cleaning sewage and multi-scale particle (7) fragments adsorbed with the impurities, repeating for multiple times until the cleaning is finished, and repeating S1 to filter smoke.
3. A double variable extension fume filtration device according to claim 2, wherein: the water amount standard introduced into the S4 is that the upper gas filtering plate (52) is immersed in the water liquid surface.
