Guiding and retarding means for gaseous stream containing solid and liquid constituents to be separated therefrom

Claim 1

APPARATUS FOR REMOVING SOLIDAND LIQUID PARTICLES FROM A FLOW OF GAS HAVING MEANS DEFININ A FIRST SPACE FOR RECEIVING SAID FLOW OF GAS AND MEANS DEFINING A SECOND SPACE FOR PURIFYING SAID GAS FLOW BY FURTHER REMOVAL OF SAID PARTICLES, SAID FIRST SPACE HAVING AN INLET AND AN OUTLET HAVING GREATER CROSS SECTIONAL AREA THAN SAID INLET, CURVED GUARD PLATES IN SAID FIRST PSACE IN THE PATH OF SAID GAS FLOW FOR CHANGING THE DIRECTION OF FLOW OF SAID FLOW OF GAS THROUGH NINETY DEGREES AND IN A DIRECTION FOR FLOWING OUT OF SAID OUTLET, MEANS TO RETARD THE GAS FLOW LEAVING SAID FIRST SPACE AND FOR EFFECTING A SUBSTANTIALLY UNIFORM VELOCITY DISTRIBUTION CROSS SECTIONALLY IN SAID GAS FLOW AND FOR REVERSING ITS DIRECTION OF TRAVEL WHILE RETARDING SAID GAS FLOW AND EFFECTING SAID UNIFORM VELOCITY DISTRIBUTION COMPRISING A LONGITUDIANLLY EXTENDING DIFFUSOR FOR RECEIVING HE GAS FLOW FROM SAID FIRST SPACE OUTLET AND CHANGING ITS PATH OF FLOW AND CAUSING IT TO FLOW IN A REVERSE DIRECTION INTO SAIDSECOND SPACE, SAID DIFFUSOR BEING DISPOSED IN COMMUNICATION WITH SAID TWO SPACES AND HAVING SURFACES COMPRISING SIDE SURFACEWS DIVERGING IN A DIRECTION IN WHICH SAID GAS FLOWS WHEN LEAVING SAID FIRST SPACE OUTLET TO EFFGECT RETARDATION AS SAID GAS FLOW IS RECEIVED IN SAID DIFFUSOR AND OTHER SURFACES DISPOSED IVERGINING A DIRECTION CORRESPONDING TO SAID REVERSE DIRECTIOPN FOR EFFECTING ING SAID GAS FLOW INTO SAID SECOND SPACE AND FOR EFFECTING FURTHER RETARDATION OF SAID GAS FLOW IMMEDIATELY SUBSEQUENT TO REVERSAL OF DIRECTION OF FLOW THEREOF, SAID DIFFUSOR SURFACES COMPRISING A SURFACE CONFIGURED TO EFFECT SAID REVERSAL OF DIRECTION OF FLOW OF SAID GAS FLOW, AND PARTICLE REMOVAL MEANS IN SAID SECOND SPACE.
