Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
23 words
The apparatus of claim 1 further characterized in that spinner is rotatably mounted for rotation thereof by the force of said rising gas.
Claim 2
Dependent Claim
66 words
The apparatus of claim 1 further characterized in that a static spinner with blades curved concavely downwards is vertically mounted above the upper end of said tubes and below said gas outlet in the upper section of said tower, whereby the gas rises in a spiralling motion forcing entrained droplets of the liquid against the walls of the tower whereupon deentrainment of these droplets is effected.
Claim 3
Dependent Claim
107 words
The apparatus of claim 1 further characterized in that there is a liquid drain leading from the lowest portion of said upper section to outside said tower, and the liquid outlet from said lower section is connected by a first pipe to a pump, a second pipe leading from a replenishing supply of liquid is also connected to the pump, and the pump is in turn connected by a third pipe to said liquid inlet in said upper section, whereby liquid flowing down the walls of said tubes and through the liquid outlet in said lower section is recycled back to the upper section of said tower.
