Abstract: A system and methods for separating liquids, aerosols, and solids from a flowing gas stream whereby gas flows through a helical path formed in a separator element. Partially separated gas exits the bottom of the separator element at a generally conical cavity. Clean gas exits through an inner tube that is axially aligned beneath the helical path. Separated materials exit through an annular space between the inner tube and an outer tube. Separation occurs in the helical channels which include radially diverging walls to provide an aerodynamically efficient flow, in a region of high swirl created in a generally conical cavity beneath the separator element, and in a toroidal vortex ring created in the annular space. The area and geometry of the helical path, the conical cavity, and the inner and outer tubes is optimized to provide efficient separation at varying gas flow rates and at varying liquid loads.

Abstract: The present invention relates to a centrifugal wet type cleaner which collects contaminants within air using fine water particles to centrifugally separate the air and water from each other using the weight difference between the air and water, thereby purifying air. The centrifugal wet type cleaner has a swirl chamber in which contaminants are three-dimensionally collected using a large number of water particles sprayed by a rotating atomizing device to centrifugally separate the contaminated water having a heavy weight and collecting the contaminants from the air using a direct spiral flow generated at a downstream side of a centrifugal impeller. When compared to a conventional cleaner, since the centrifugal wet type cleaner has low energy loss and less noise, noise and energy may be reduced to improve the effect of preventing the discharge of fine dust.

Abstract: The invention is a heat exchanger that transfers heat directly between fluids which are in direct contact with each other rather than being separated by a heat conductive wall. Gas and liquid exchange heat when the gas is moved into and through a mixing chamber, and is directed to form a high speed, forced vortex gas flow. The liquid is sprayed into the mixing chamber to form droplets traveling with and mixing with the vortex gas flow. As the gas and liquid droplets move through the mixing chamber together in the vortex flow, they exchange thermal energy by direct contact. The mixing chamber length is designed so that the gas and the liquid droplets approach thermal equilibrium as the gas-liquid mixture moves into a separation chamber. Within the separation chamber, the centrifugal force of the continuing vortex movement of the gas stream separates the liquid from the gas stream and forms a layer of liquid on the separation chamber wall.

Abstract: Carbon capture is effected by mechanical means, producing out of flue gas a concentrated, cleaned, and cooled stream of carbon dioxide. This is a new method of carbon capture which avoids the limitations of known cryogenic, membrane, or chemical capture methods. A mechanically assisted turbulent flue gas scrubber comprises counter-rotating coaxial centrifugal impellers and a shrouding tank for receiving the flow from between the impellers. Feed is at the axis of rotation. Axial extraction of nitrogen and water vapor is driven by an axial pump and by back pressure from the tank while radially outward flow of carbon dioxide and scrubbing targets is driven by the impellers. Scrubbing of the concentrated targets is in high turbulence during a long residence time. Tiny centrifugation effects of innumerable turbulent eddy vortices in a shear layer between the impellers and in the tank are integrated by the forcing regime of the impellers and the axial pump.

Abstract: An apparatus and method are provided for mixing a gas and a liquid to produce a gaseous vapor of the liquid that is substantially free of droplets. Gas, e.g., carbon dioxide, is divided into first and second streams. The first stream is combined in an atomization zone with the liquid, e.g., acetic acid, to form an atomized mixture of the gas and liquid. This atomized mixture is then contacted with the second gas stream in a mixing zone within a mixing/separation chamber in which the second gas stream vaporizes substantially all of the atomized liquid, and the resulting mixture of gas, vaporized liquid and residual droplets moves to the separation zone of the mixing/separation chamber. In the separation zone, the residual droplets gravitationally separate from the vaporized mixture, and the vaporized mixture free of a substantial amount of residual droplets is removed from the chamber.

Abstract: A waste gas treatment system has a primary cooling section provided at a stage subsequent to a decomposition treatment section in which a waste gas is subjected to decomposition treatment at high temperature. The primary cooling section has a liquid spray part for spraying a liquid on the treated gas from the decomposition treatment section. A secondary cooling section cools the treated gas sprayed with the liquid in the primary cooling section to reduce the volume of the treated gas. Further, a particle collecting section injects a liquid into the treated gas cooled in the secondary cooling section to collect fine particles contained in the treated gas.

Abstract: An exhaust gas treatment apparatus for treating exhaust gas generated in semiconductor manufacturing processes. It includes a main pipe, a gas vortex means, a water vortex means, an U pipe and a discharge pipe. The main pipe transforms the exhaust gases to waste powder which are discharged out through the U pipe and the discharge pipe. The gas vortex means and water vortex means are located below the main pipe for generating annular and even downward gas flow and water flow at the outlet of the main pipe for preventing reflux of waste powder from entering into the main pipe. Waste powder thus won't deposit around the outlet. Scraper in the main pipe won't be stuck or deformed. Waste powder may be discharged out through the U pipe and discharge pipe smoothly and efficiently.
