Abstract: The disclosure is of gas-cleaning apparatus comprising a chamber having a downwardly vertical gas and fluid flow path, with the gas and fluid moving at high velocity. One or more layers of solids is disposed across the path of gas and fluid flow, and these solids and the spaces between them act as multiple venturi scrubbers and impingement surfaces so that the gas is cleaned by agglomeration and absorption. A vibrator is coupled to the layers of solids for vibrating them to prevent matter removed from the gas from adhering thereto and blocking the passages therebeween.Also disclosed is a centrifugal cyclone separator, adapted to be coupled to the output of the above-described gas scrubber, comprising an upright chamber containing a rotatable cylinder carrying blades on its outer surface, the free edges of the blades being positioned close to the inner wall of the chamber. The blade configuration and high rotational velocity and long distance travel of the gases provide improved separating action.

Abstract: Countercurrent flow absorber and desorber devices are provided for use in absorption cycle refrigeration systems and thermal boosting systems. The devices have increased residence time and surface area resulting in improved heat and mass transfer characteristics. The apparatuses may be incorporated into open cycle thermal boosting systems in which steam serves both as the refrigerant vapor which is supplied to the absorber section and as the supply of heat to drive the desorber section of the system.

Abstract: An absorber intercooler having a heat exchanger formed integrally therein. The absorber intercooler includes a cylindrical outer casing having a tube bundle disposed longitudinally therein. Inlet and outlet ports are provided in the cylindrical casing to allow for the flow of refrigerant around the tube bundle. Upper and lower end plates, having a plurality of openings therein, seal the upper and lower ends of the bundle. A liquid inlet pipe provides a flow of liquid absorbent through the upper end plate into the tube bundle. A vapor inlet pipe provides a flow of vapor into the bottom of the intercooler, and the vapor flows through a central opening in the lower end plate into a centrally disposed vapor flow pipe. The vapor flows upwardly therein through the upper end plate. A cap is provided on the upper end of the vapor flow pipe to prevent liquid absorbent from flowing down into the pipe, and also provides for an even radial distribution of the vapors at the cap.

Abstract: An externally cooled, absorption engine apparatus and method, the apparatus including a closed cycle system having a first fluid and a second fluid, the first fluid constituting a working fluid and having a relatively lower boiling point while the second fluid constitutes a solvent for the first fluid and has a relatively higher boiling point and a relatively high degree of absorptivity for the first fluid. The apparatus further includes a distillation column, a superheater, a mechanical expansion engine, an externally cooled absorption column, and heat exchange apparatus. The distillation column separates the first fluid or working fluid from the solvent with heat energy supplied by an external combustion source and the superheater increases the thermal energy thereof prior to passing the working fluid through the mechanical expansion engine. The mechanical expansion engine converts thermal engine in the working fluid vapor to mechanical energy.

Abstract: The packing of a tower or column for heat exchange, material exchange, contacting of two fluids with one another and chemical reaction consisting of a stack of elongated members having two walls inclined to one another and joined at a third wall, the first two walls being each formed with elongated vibratile elements interdigitated with vibratile elements of another packing member so that when the body of packing is traversed by one or more fluids, the vibratile elements are set into vibration.

Abstract: An air cooled heat exchanger provided with water distribution means for wetting the surfaces of air flow passages with a thin film of water, which by evaporation enhances the cooling of a fluid. The fluid flows through the heat exchanger in passages arranged in generally parallel, spaced apart layers. A series of metallic fin sheets, extending between the layers, maintain the separation between the layers and define a plurality of air passages. Water is distributed into the air passages as a liquid through slot means disposed on the edge of the layers, at the side where the air stream enters the heat exchanger. The air stream causes the water to spread in a thin film over the surfaces of the air passages, resulting in improved cooling of the fluid by evaporation of the water. Provision is made for collecting any excess water at the side of the heat exchanger where the air stream exits.

Abstract: A counterflow evaporative heat exchanger comprises a vertical conduit in which a coil assembly is positioned. A fluid to be cooled or condensed passes through the coil assembly while water is sprayed downwardly over it and air is blown upwardly through it. The coil assembly comprises a plurality of tubes which at each level in the assembly are spaced apart from each other in the horizontal direction by an amount greater than the diameter of the tubes. This has been found to improve heat transfer in comparison to counterflow evaporative heat exchangers using closely packed coil assemblies.

Abstract: A contact plate for mass-exchange columns comprises a base having receiving and discharge pockets for liquid. The base also supports concave troughs, each trough extending between the receiving pocket and the discharge pocket having its walls provided with apertures for the passage of gas extending tangentially in the same direction to form gas flows whirled in a direction transversely of the trough toward one of the side edges thereof which is provided with a guide apron comprising an extension of the trough wall.

Abstract: This is a continuous process for producing a stream of purified and humidified fuel gas which may be burned in a gas turbine to produce mechanical work and electrical energy without contaminating the environment. In the process, a feed stream of raw fuel gas is preferably produced by the partial oxidation of a hydrocarbonaceous fuel with a free-oxygen containing gas, optionally in the presence of a temperature moderator. The raw fuel gas stream is then preferably saturated with water during cooling and cleaning operations. It is then passed in indirect countercurrent heat exchange with a stream of purified fuel gas containing substantially no water. The latter stream was produced by cooling and purifying said raw fuel gas stream. At least a portion of the water which is condensed out of the raw fuel gas during said cooling operation is separated and revaporized into said purified fuel gas stream. The resulting stream of purified and humidified fuel gas may be used as fuel in a gas turbine.

Abstract: An air-cooled tower for cooling of fluid wherein a vortex is established within a vertically standing cylinder.Air entering through the upper portion of the cylinder is directed tangentially and downwardly, establishing a downwardly flowing vortex which is reversed at the bottom forming a smaller diameter intense upwardly flowing vortex. Additional air is induced through the center of the cylinder at the bottom. Heat exchange between the fluid to be cooled and the air is through indirect heat exchange surface or direct injection of the fluid. Evaporative cooling is accelerated due to the turbulent conditions, and the centrifugal action reduces the water carryover in the airstream exiting from the top of the cylinder. A turbine-fan combination centrally located at the bottom of the cylinder permits supplementing the airflow under low-wind conditions and extracting energy from the induced airflow under high wind conditions.

Abstract: A low cost, preformed, synthetic resin, indirect air cooled atmospheric heat exchanger especially adapted for use in water cooling towers is provided which exhibits enhanced water cooling properties notwithstanding fabrication thereof from relatively inexpensive, corrosion-free polyvinyl chloride or like materials heretofore thought to have insufficient heat conductivity for practical use in heat exchangers.

Abstract: Air contaminated with combustible dust particles is removed and subjected to a high density air scrubber which safely removes the fine combustible dust particles from the contaminated air. The resulting water saturated, cleansed air is mixed with a continuously regulated amount of drier outside air until a desired absolute humidity is achieved, the regulation being responsive to the relative humidity changes within a work area in which the humidity is to be controlled. The air mixture is then conveyed into the work area which imparts a known temperature rise thereto. The temperature rise lowers the relative humidity of the air mixture to the desired level.
