Wet-cleaning of gases

Claim 1

A METHOD FOR WET CLEANING DUST-LADEN GASES IN APPRATUS HAVING A SUPPLY CHAMBER OPENING DOWNWARDLY TO A PRIMARY WASHING LIQUID RESERVOIR, INCLUDING THE STEPS OF INTRODUCING PRIMARY WASHING LIQUID FROM SAID RESERVOIR, PERIPHERALLY INTO SAID CHAMBER TRANSVERSE TO THE DIRECTION OF GAS FLOW TO CAUSE ATOMIZATION OF SAID LIQUID IN SAID GAS AND AGGLOMERATION OF SAID DUST PARTICLES WITH SAID ATOMIZED LIQUID CAUSING THE GAS TO FLOW DOWNWARDLY TOWARD THE RESERVOIR AND THEN SUBSTANTIALLY HORIZONTALLY SO AS TO SEPARATE HEAVIER PARTICLES FROM THE GAS FLOW SEPARATING THE REMAINING AGGLOMERATED DUST PARTICLES AND A MAJOR PART OF THE ATOMIZED LIQUID FROM THE GAS DURING SAID HORIZONTAL FLOW BY PASSING SAID GAS THROUGH A FILTERMAT WHILE CAUSING THE AGGLOMERATED DUST PARTICLES TO ACCUMULATE ON ONE SIDE OF SAID FILTER-MAT COLLECTING A MAJOR PORTION OF THE ATOMIZED PRIMARY WASHING LIQUID AND THE AGGLOMERATED DUST PARTICLES IN SAID RESERVOIR, AND UTILIZING THE COLLECTED LIQUID AS THE SOURCE OF PRIMARY WASHING LIQUID; THE IMPROVEMENT COMPRISING THE STEPS OF INTERMITTENTLY INTRODUCING A QUANTITY OF SEPARATE WASHING LIQUID OBLIQUELY TO SAID ONE SIDE OF THE FILTER-MAT IN ORDER TO CLEAN SAID FILTER-MAT AND COLLECTING SAID SEPARATE LIQUID IN SAID RESERVIOR, AND CONTROLLING SAID QUANTITY IN RESPONSE TO CHANGES IN THE LEVEL OF SAID LIQUID IN THE RESERVOIR TO MAKE-UP THE PORTION OF SAID ATOMIZED PRIMARY WASHING LIQUID NOT SEPARATED FROM THE GAS FLOW TO THEREBY MAINTAIN CONSTANT THE QUANTITY OF LIQUID IN THE RESERVOIR.

Claim 2

A METHOD FOR WET CLEANING DUST-LADEN GASES IN APPRATUS HAVING A SUPPLY CHAMBER OPENING DOWNWARDLY TO A PRIMARY WASHING LIQUID RESERVOIR, INCLUDING THE STEPS OF INTRODUCING PRIMARY WASHING LIQUID FROM SAID RESERVOIR, PERIPHERALLY INTO SAID CHAMBER TRANSVERSE TO THE DIRECTION OF GAS FLOW TO CAUSE ATOMIZATION OF SAID LIQUID IN SAID GAS AND AGGLOMERATION OF SAID DUST PARTICLES WITH SAID ATOMIZED LIQUID CAUSING THE GAS TO FLOW DOWNWARDLY TOWARD THE RESERVOIR AND THEN SUBSTANTIALLY HORIZONTALLY SO AS TO SEPARATE HEAVIER PARTICLES FROM THE GAS FLOW SEPARATING THE REMAINING AGGLOMERATED DUST PARTICLES AND A MAJOR PART OF THE ATOMIZED LIQUID FROM THE GAS DURING SAID HORIZONTAL FLOW BY PASSING SAID GAS THROUGH A FILTERMAT WHILE CAUSING THE AGGLOMERATED DUST PARTICLES TO ACCUMULATE ON ONE SIDE OF SAID FILTER-MAT COLLECTING A MAJOR PORTION OF THE ATOMIZED PRIMARY WASHING LIQUID AND THE AGGLOMERATED DUST PARTICLES IN SAID RESERVOIR, AND UTILIZING THE COLLECTED LIQUID AS THE SOURCE OF PRIMARY WASHING LIQUID; THE IMPROVEMENT COMPRISING THE STEPS OF INTERMITTENTLY INTRODUCING A QUANTITY OF SEPARATE WASHING LIQUID OBLIQUELY TO SAID ONE SIDE OF THE FILTER-MAT IN ORDER TO CLEAN SAID FILTER-MAT AND COLLECTING SAID SEPARATE LIQUID IN SAID RESERVIOR, AND CONTROLLING SAID QUANTITY IN RESPONSE TO CHANGES IN THE LEVEL OF SAID LIQUID IN THE RESERVOIR TO MAKE-UP THE PORTION OF SAID ATOMIZED PRIMARY WASHING LIQUID NOT SEPARATED FROM THE GAS FLOW TO THEREBY MAINTAIN CONSTANT THE QUANTITY OF LIQUID IN THE RESERVOIR.
