1. according to the device, the water tank 3 and the air guide module which are pre-stored with the aqueous solution are arranged in the inner cavity of the assembly shell 2, the flue gas exhausted from the chimney 1 is guided into the aqueous solution stored in the water tank 3, and the aqueous solution is utilized to capture floating particulate impurities in the flue gas, so that the flue gas purifying effect of the device is improved, and the defect of poor flue gas purifying effect in the prior art is overcome.
2. This device is equipped with the floating plate 45 of a plurality of inserted bars 471 through setting up the bottom at the inside activity of water tank 3 to set up a plurality of doctor-bars 473 on the circumference lateral wall of every inserted bar 471, at the flue gas by the inner chamber bottom of water tank 3 upwards emit this in-process of surface of water, utilize the kinetic energy that floating plate 45 produced this process to utilize, drive inserted bar 471 and draw forth from top to bottom in air vent 43, and then drive doctor-bar 473 and cut the inner wall of rubbing air vent 43, utilize inserted bar 471 and doctor-bar 473 to dredge air vent 43, prevent air vent 43 by the floating particulate matter jam in the flue gas.
3. The water vapor capturing rope 62 of the device is formed by weaving the metal wire 621 and the water absorbing wire harness 622, so that the tensile strength of the water vapor capturing rope 62 is guaranteed, the characteristic that the water absorbing wire harness 622 is good in water absorption is utilized, water drops condensed on the water vapor capturing rope 62 are absorbed in time, the water absorbing wire harness 622 saturated in water absorption is conveniently brought into the bearing shell 631, the cooling device 634 is utilized for cooling the water drops, the water vapor capturing effect of water vapor capturing is improved, and the flue gas purifying effect of the device is further improved.
