step one, when the hot blast is made by the operator through the hot blast stove, firstly, the operator pours the cold blast into the hot blast stove body through the air inlet 15, because there is a heating cavity 12 between the hot blast stove body and the flue gas cavity, therefore, the cold blast enters into the heating cavity 12, the cold blast becomes hot blast after being heated by the base 1 and flows out through the air outlet 16, the base 1 can generate flue gas when heating the cold blast through coal, because the lower barrel 17 of the flue gas cavity is communicated with the base 1 through a plurality of air inlet pipes 19, therefore, the flue gas enters into the flue gas cavity through a plurality of air inlet pipes 19, the hot gas and the flue gas can not be mixed, when the flue gas enters into the flue gas cavity, because the inner part of the lower barrel 17 of the flue gas cavity is provided with the first filter screen 26, therefore, the flue gas entering into the flue gas cavity is primarily filtered.

Step two, when the flue gas enters the dedusting barrel 2 from the flue gas cavity, because the connecting pipeline is respectively communicated with the flue gas outlet 30 and the flue gas inlet 31 through the two pipe joints 32, the flue gas enters the dedusting barrel 2, then, the four first water spray heads 10 spray water mist to the flue gas in the dedusting barrel 2, the water mist is mixed with the flue gas under the action of the stirring mechanism, the mixing of the flue gas and the water mist can generate sludge, because the bottom of the dedusting barrel 2 is provided with the plurality of sewage outlets 34, the sludge flows into the hopper 33 through the plurality of sewage outlets 34, after the sludge flows into the purifying barrel 4 through the hopper 33, an operator pours the purifying liquid into the purifying barrel 4 through the feed pipe 37, the driving motor 40 drives the first rotating rod 39 to rotate, the first rotating rod 39 rotates to drive the first stirring rods 41, and the first stirring rods 41 mix the dirt and the purifying liquid, in the process of stirring by the first stirring rods 41, each first scraping and rubbing rod 42 scrapes dirt on the inner wall of the purification barrel 4, so that the service life of the machine is ensured, and purified water flows into the water supply barrel 35 through the water outlet 38 and is recycled.

Step three, in the flue gas filters through dust removal bucket 2 and then comes to rose box 43, four second sprinkler bead 11 in rose box 43 further spray to the flue gas in rose box 43 thereupon, then, the flue gas passes second filter screen 44, and second filter screen 44 can carry out the dismouting through the manual work, because second filter screen 44 passes through two fixture block 46 joints in corresponding draw-in groove 45, consequently, operating personnel can take out through handle 47.

Step four, when the stirring mechanism mixes the flue gas and the water mist, the rotating motor 50 drives the second rotating rods 49 to rotate, the second rotating rods 49 rotate to drive the second stirring rods 53 to mix the flue gas and the water mist, each second scraping and rubbing rod 51 scrapes dirt on the inner wall of the dust removing barrel 2 when the second stirring rods 53 rotate, the dirt flows downwards, the flue gas is mixed with the water mist through the stirring mechanism, the flue gas enters a space between the top cover 8 and the second filter screen 44 through the second filter screen 44, the third water spray heads 52 finally spray the flue gas, and finally the flue gas is purified and then discharged through the smoke outlet pipe 5.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
