Abstract
Abstract An apparatus and system for the purification of residual gases, such as flue and exhaust gases which may contain soot, is provided wherein the gases to be purified are sucked into a chamber, treated with liquid, e.g., an aqueous liquid, in the chamber whereupon condensation of vapors within the gases is initiated, mix of the gas and liquid being passed through a Venturi type constriction and thence to an enclosed space above a first tank which surrounds the chamber where the liquid and solid components separate from the gas. The heavier solid components settle to the bottom of the liquid in the first tank from which liquid may be withdrawn. The gases separating in the space above the first tank build up a pressure and are passed below the surface of a liquid in a second tank whereupon they are further purified and on escaping from the second tank are released to the atmosphere. Means are provided for forced circulation of the liquid to the chamber and for adding makeup liquid.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
176 words
A system for removing impurities, including soot from residual gases such as flue and exhaust gases comprising an enclosed tank having a liquid retaining lower portion and a gas holding space above the liquid retaining portion, means for maintaining liquid at a predetermined level in said tank, a Venturi-type suction means having a Venturi-type constricted discharge opening and positioned with the discharge opening below the predetermined liquid level, a first pipe means extending outside the enclosed tank connecting said Venturi-type suction means to a source of residual gas to be purified, said Venturi-type suction means comprising a nozzle constructed and arranged to supply liquid to the constricted opening, pump means including a pipe line for passing liquid from the tank under pressure to the nozzle of the Venturi-type suction means, a second pipe means connecting the discharge opening of the Venturi-type suction means to the gas holding space above the liquid retaining portion, a substantial portion of said second pipe means being immersed in the liquid retaining portion of said tank below the predetermined liquid level.
Claim 2
Independent Claim
176 words
A system for removing impurities, including soot from residual gases such as flue and exhaust gases comprising an enclosed tank having a liquid retaining lower portion and a gas holding space above the liquid retaining portion, means for maintaining liquid at a predetermined level in said tank, a Venturi-type suction means having a Venturi-type constricted discharge opening and positioned with the discharge opening below the predetermined liquid level, a first pipe means extending outside the enclosed tank connecting said Venturi-type suction means to a source of residual gas to be purified, said Venturi-type suction means comprising a nozzle constructed and arranged to supply liquid to the constricted opening, pump means including a pipe line for passing liquid from the tank under pressure to the nozzle of the Venturi-type suction means, a second pipe means connecting the discharge opening of the Venturi-type suction means to the gas holding space above the liquid retaining portion, a substantial portion of said second pipe means being immersed in the liquid retaining portion of said tank below the predetermined liquid level.
Claim 3
Dependent Claim
54 words
The system as claimed in claim 1 comprising, a second tank adjacent said first tank having a liquid retaining lower portion and an enclosed upper portion having a gas-escape duct, means for feeding gas from the gas-holding space of said first-named enclosed tank to a point within the liquid-retaining portion of said second tank.
Claim 4
Dependent Claim
21 words
The system as claimed in claim 2, comprising valve means for feeding fresh treating liquid to said first and second tanks.
Claim 5
Dependent Claim
51 words
The system as claimed in claim 1 wherein said Venturi-type suction means comprises a valved pipe line connecting the pipe line upstream of said nozzle to the Venturi device downstream of the constricted discharge opening whereby by-pass a portion of the liquid fed by said pump to said Venturi-type suction means.
