Combustion furnace

[0031] In the figure, the coal is placed on the coal planting net (8) through the coal inlet (7), the air required for combustion is provided by the air inlet (9), and it is burned in the combustion tower (1), and the smoke and waste gas generated by the combustion pass through The flame outlet (10) is discharged into the first sprinkler tower (2), and the shower (11) connected to tap water sprays the smoke and exhaust gas, and the smoke is washed into the water flow and discharged into the first sedimentation tank through the tower drain pipe (12). (4), under the filtering effect of the filter membrane (16), the dust of PM2.5 remains under the membrane, and the dust removal water flow is discharged through the pool drain pipe (19), and the isolation net (17) can reduce the scouring effect of the water flow on the bottom sludge . The exhaust gas that has been rinsed for the first time is passed into the solution of the drug pool (6) through the drug spraying connecting pipe (13),
