Method of treating gases for liberating solid particles and moisture therefrom

Claim 1

THE METHOD OF TREATING INDUSTRIAL GASES FOR REMOVING SOLID PARTICLES AND LIQUID DROPLETS THEREFROM, WHICH COMPRISES SUBJECTING THE GASES TO A SCRUBBING ACTION CONSISTING ESSENTIALLY OF: (A) CAUSING GASES WHICH EMANATE FROM A SODA HOUSE BAILER TO ASCEND VERTICALLY IN A CHAMBER HAVING A VERTICAL WALL; (B) FORMING A SERIES OF VERTICALLY SPACED CURTAINS OF SCRUBBING LIQUID, EACH OF SAID CURTAINS BEING DISPOSED GENERALLY HORIZONTALLY IN SAID CHAMBER AND IN THE PATH OF ASCENDING FLOW OF THE GASES IN SAID CHAMBER; (C) DELIVERING SCRUBBING LIQUID ONTO EACH OF A PLURALITY OF VERTICALLY SPACED HORIZONTAL SURFACES TO CAUSE SIMULTANEOUSLY ROTATING ALL OF SAID SURFACES TO CAUSE THEM TO FLING THE SCRUBBING LIQUID THEREFROM IN THE FORM OF FINE DROPLETS BY CENTRIFUGAL FORCE, THEREBY TO FORM SAID SERIES OF CURTAINS AND TO CAUSE SAID DROPLETS OF SCRUBBING LIQUID TO IMPINGE UPON SAID VERTICAL WALL OF SAID CHAMBER, THE PERIPHERAL SPEED OF SAID SURFACES CORRESPONDING TO NOT LESS THAN 10 METERS PER SECOND FOR A SURFACE HAVING A DIAMETER OF 80 CENTIMETERS, SAID SCRUBBING LIQUID BEING WASTE SULFATE LIQUOR. (D) CONTROLLING THE QUANTITY OF SAID SCRUBBING LIQUID DELIVERED TO SAID ROTATING SURFACES SO AS NOT TO EXCEED A RATE OF APPROXIMATELY 100 LITERS PER MINUTE FOR ROTATING SURFACES OF THE AFORESAID DIAMETER AND PERIPHERAL SPEED; (E) CONTROLLING THE RATE OF ASCENSION OF THE GASES IN SAID CHAMBER SO AS NOT TO EXCEED AN AVERAGE SPEED OF ABOUT TWO METERS PER SECOND, CALCULATED ON THE FREE AREA BETWEEN THE PERIPHERY OF SAID ROTATING SURFACES AND SAID WALL OF THE CHAMBER; (F) DISCHARGING THE SCRUBBED GAS AT THE TOP OF SAID CHAMBER AFTER IT HAS PASSED THE UPPERMOST OF SAID SURFACES; AND (G) REMOVING AT THE BOTTOM OF SAID CHAMBER, SCRUBBING LIQUID COLLECTED FROM SAID WALL THEREOF.

Claim 2

THE METHOD OF TREATING INDUSTRIAL GASES FOR REMOVING SOLID PARTICLES AND LIQUID DROPLETS THEREFROM, WHICH COMPRISES SUBJECTING THE GASES TO A SCRUBBING ACTION CONSISTING ESSENTIALLY OF: (A) CAUSING GASES WHICH EMANATE FROM A SODA HOUSE BAILER TO ASCEND VERTICALLY IN A CHAMBER HAVING A VERTICAL WALL; (B) FORMING A SERIES OF VERTICALLY SPACED CURTAINS OF SCRUBBING LIQUID, EACH OF SAID CURTAINS BEING DISPOSED GENERALLY HORIZONTALLY IN SAID CHAMBER AND IN THE PATH OF ASCENDING FLOW OF THE GASES IN SAID CHAMBER; (C) DELIVERING SCRUBBING LIQUID ONTO EACH OF A PLURALITY OF VERTICALLY SPACED HORIZONTAL SURFACES TO CAUSE SIMULTANEOUSLY ROTATING ALL OF SAID SURFACES TO CAUSE THEM TO FLING THE SCRUBBING LIQUID THEREFROM IN THE FORM OF FINE DROPLETS BY CENTRIFUGAL FORCE, THEREBY TO FORM SAID SERIES OF CURTAINS AND TO CAUSE SAID DROPLETS OF SCRUBBING LIQUID TO IMPINGE UPON SAID VERTICAL WALL OF SAID CHAMBER, THE PERIPHERAL SPEED OF SAID SURFACES CORRESPONDING TO NOT LESS THAN 10 METERS PER SECOND FOR A SURFACE HAVING A DIAMETER OF 80 CENTIMETERS, SAID SCRUBBING LIQUID BEING WASTE SULFATE LIQUOR. (D) CONTROLLING THE QUANTITY OF SAID SCRUBBING LIQUID DELIVERED TO SAID ROTATING SURFACES SO AS NOT TO EXCEED A RATE OF APPROXIMATELY 100 LITERS PER MINUTE FOR ROTATING SURFACES OF THE AFORESAID DIAMETER AND PERIPHERAL SPEED; (E) CONTROLLING THE RATE OF ASCENSION OF THE GASES IN SAID CHAMBER SO AS NOT TO EXCEED AN AVERAGE SPEED OF ABOUT TWO METERS PER SECOND, CALCULATED ON THE FREE AREA BETWEEN THE PERIPHERY OF SAID ROTATING SURFACES AND SAID WALL OF THE CHAMBER; (F) DISCHARGING THE SCRUBBED GAS AT THE TOP OF SAID CHAMBER AFTER IT HAS PASSED THE UPPERMOST OF SAID SURFACES; AND (G) REMOVING AT THE BOTTOM OF SAID CHAMBER, SCRUBBING LIQUID COLLECTED FROM SAID WALL THEREOF.
