through the setting of above-mentioned structure, the pasty liquid and the unnecessary sodium hydroxide solution after sodium hydroxide water smoke and dust combine all will fall on arc 3 upper portion, so then make arc 3 play the effect of condensation plate, when waste gas gets into in the jar body 1, will at first through the cooling of arc 3 bottom to can play the effect of certain cooling.
Referring to fig. 1 to 6, in the present invention, when in use, firstly, the end of the air inlet pipe 101 is fixedly connected to the exhaust gas exhaust pipe of the kiln through the bolts, flanges and other connecting components in the prior art, and then the exhaust gas can be discharged, and the exhaust gas can move into the region where the rotary vane 46 is located through the air inlet pipe 101 and the air pipe 103; meanwhile, the servo motor 21 drives the rotating shaft 2 to rotate, the rotating shaft 2 also drives the rotating blades 46 to rotate, under the action of the rotating centrifugal force of the rotating blades 46, the triggering plate 461 pulls the second spring 462 to slide outwards, so that the triggering plate 461 moves to the lower part of the locking plate 45, the bottom of the locking plate 45 and the upper surface of the triggering plate 461 are magnetically repelled, the locking plate 45 is lifted upwards, the blocking of the spraying pipe 42 is relieved, at the moment, under the action of the liquid pressure in the water tank 41, sodium hydroxide solution is sprayed outwards from the spraying pipe 42, the sprayed sodium hydroxide solution just falls on the rotating blades 46, a layer of sodium hydroxide film is formed on the plane where the rotating blades 46 are located under the action of rotating cutting, at the moment, waste gas can pass through the film, the sodium hydroxide water mist can cool the waste gas firstly, and then can be condensed with the dust in the waste gas, so that the dust can fall onto the spraying pipe 3 to be discharged, at the moment, the sodium hydroxide can also effectively absorb carbon dioxide and the dust in the waste gas, and the dust can be mutually cooled, and the dust can be discharged onto the filter screen 47, and the dust can be cooled down together, and the filter screen can be matched with the dust-removing function can be realized, and the dust-removing function is realized by the filter plate is realized;
meanwhile, when the locking plate 45 and the triggering plate 461 repel each other magnetically, the locking plate 45 moves up and pushes the movable rod 441 to move up, so that the movable rod 441 contacts the bottom of the first filter screen 47 and pushes the first filter screen 47 to move up under the stretching effect of the third spring 471, after the triggering plate 461 rotates beyond the lower portion of the locking plate 45, the locking plate 45 and the first filter screen 47 are reset under the resilience effect of the first spring and the third spring 471, so that the first filter screen 47 oscillates up and down, and accordingly, the filtered objects assisted at the bottom of the first filter screen 47 can be shaken off along with the rotation of the rotating blade 46, the filtered objects can be cleaned down further under the scraping effect of the supporting rod 49 and the cleaning brush plate 491, finally, the filtered objects drop onto the arc plate 3 to be discharged, and the cooled, dust-reduced and waste gas after the removal of greenhouse gases can be discharged through the air outlet pipe 102.
It should be noted that, specific model specifications of the motor need to be determined by selecting a model according to actual specifications of the device, and a specific model selection calculation method adopts the prior art in the field, so detailed description is omitted.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
