Abstract: The invention relates to a device and method for treating a hot gas flow containing slag and to an entrained-bed gasifier system that comprises the device. The device comprises, in a housing, an inlet arranged at the top for the hot gas flow, an immersion pipe, which is arranged vertically and concentrically in the housing and into which the inlet opens, a coolant bath, into which a lower section of the immersion pipe is immersed, and at least one raw gas outlet opening for cooled raw gas that has been freed of slag. The lower section of the immersion pipe is designed as a radially expanded gas distributor bell in the coolant bath. Said gas distributor bell is formed by a substantially conical jacket surface having a cross-section that expands downward, wherein the jacket surface has a plurality of gas passage openings, which are distributed over the circumference of the gas distributor bell. The dimensions of the gas passage openings increase with the immersion depth in the coolant bath.

Abstract: A system for removing unwanted contaminates from gases using a scrubber, which comprises a housing, a reaction chamber having a liquid level, an inlet connected to a source containing gases to be scrubbed with a contamination concentration greater than zero ppb to saturation. A gas exit port connected to the housing is used for evacuating scrubbed gas and a sintered permeable membrane is disposed across the reaction chamber, which provides a reaction zone in the plurality of pores when gases to be scrubbed are introduced to the membrane on a first side while the membrane is immersed in the lean liquid; and a cleaned gas on a second side wherein the clean gas initially has a drop in contamination concentration of at least 99 percent and gradually decreasing to 70 percent as additional gases to be scrubbed are introduced to the plurality of pores without replacing the lean liquid.

Abstract: An electrostatic phase change generating apparatus is described. The apparatus causes a change of state to occur in an input gas, for example, ambient air. The electrostatic phase change generating apparatus removes moisture from air, and may be used to generate water from air, dehumidify air, cool air, and the like. The ability to generate water from air has global importance as the need for clean water increases each year. The electrostatic phase change generating apparatus uses high voltage but low current allowing for very energy efficient operations. The electrostatic phase change generating apparatus uses a phase change vessel containing a liquid, a bubbler immersed in the liquid for conveying a gas, and a high voltage source to bias the liquid with respect to an upper electrode.

Abstract: An exhaust gas cooling and particulate scrubbing system for automobiles includes a first stage intercooler for initial, indirect cooling of the exhaust gas and a direct exhaust gas cooling and scrubbing device preferably positioned downstream in the exhaust system therefrom. The intercooler is designed to provide circulation of a liquid cooling medium by convection and has airflow ducts positioned within a surrounding jacket oriented to permit air to move therethrough during movement of the automobile. The a direct exhaust gas cooling and scrubbing device passes the exhaust gas through a liquid cooling medium whereby the exhaust gas is cooled in an effort to trap suspended particulates in the liquid cooling medium.

Abstract: An aeration tank used in a method of treating effluent includes a pipe for transporting the effluent from the source to the tank bottom and a discharge duct having a siphon effect for tapping off an overflow from the tank as more effluent is added from the source. An array of generally horizontal pipes is located in the tank having a series of exit holes along their length and connected to an air plenum at one side wall for feeding air into the end of each of the pipes, the pipes being arranged in columns one above another such that the air escapes from the pipes of the array through the holes to inject air into the effluent in the tank at positions spaced transversely, longitudinally and vertically. The pipes have flat upper discharge surfaces. Above each pipe is provided a collector channel which collects bubbles as they get too large and channels them to one end to be replaced by fresh small bubbles from a next above pipe.

Abstract: Particulates are removed from a gas stream by contact with a liquid. The gas stream is conveyed through an inlet channel, towards a liquid reservoir which is located below a perforated sheet. Gas flowing through holes in the sheet creates a pressure drop between the inlet channel and an outlet area above the sheet. This pressure drop draws liquid up from the reservoir, through a relatively narrow liquid transfer channel, so that the liquid covers the sheet. Gas flowing through holes in the sheet therefore encounters a layer of liquid located immediately above the sheet. Particulates in the gas are captured by the liquid in this layer. The device requires no pump for moving the liquid through the system, the liquid being transferred solely as a result of the pressure drop induced by the flow of gas.

Abstract: Provided herein is an apparatus for scrubbing either acidic or alkaline impurities from gas streams, wherein the gas streams to be scrubbed exist at a pressure which is only slightly higher than ambient pressure. An apparatus according to a preferred form of the invention exists substantially in the shape of a rectangular or cubic solid, having an inlet pipe which is directed to an inner chamber having a wall portion which functions as a manifold, including a plurality of gas conduction tubes in fluid contact with the inner chamber, and into which tubes the gas to be scrubbed enters. The gas to be scrubbed passes through holes in the walls of the gas conduction tubes and contacts a liquid absorbent substance present in the interior confines of the apparatus, which liquid is capable of reacting with one or more impurities in the gas stream, thus eliminating the impurities from the gas stream. The gas stream so treated emerges from the apparatus through a gas outlet provision.

Abstract: An improved air filtration system is provided for a kitchen island so as to cleanse cooking vapors from the air. The system includes an updraft or downdraft air inlet vent for capturing, either individually or simultaneously, the vapor-containing air generated during the cooking process. The captured air is directed through an exhaust duct to an air filter which removes the cooking vapors from the air. The filtered air is then discharged back into the kitchen. The filtered air may also be dehumidified or heated, and a fragrance may optionally be provided to the filtered air. The air filtration system can also be used simply as air cleaner for the kitchen with the option of adding a fragrance to the air.

Abstract: A high flow rate bubbler system and method are provided for producing a stable, easily controllable source of chemical vapors to a downstream process. The bubbler system is equipped with a vaporizer unit connected to its gas outlet tube. This vaporizer unit slows the gas velocity to enhance settling of entrained droplets and contacts the exiting gas with a high thermal mass, heated surfaces to promote heat transfer and evaporation of the entrained droplets.

The apparatus is subdivided into two parts, an upper one which includes the support body of a suction motor unit, and a lower one which includes the labyrinth. The lower one provides an intermediate washable filter. The support body is housed in an opening coated by an acoustic insulating material.

Abstract: An ion chromatography system analyzes the environment in semiconductor equipment for foreign materials. The system includes an impinger section for preparing a sample of the atmosphere, and an ion chromatography section. The impinger section includes an absorbent solution vessel, suction and exhaust piping connecting the vessel to the environment, and a pump for transporting atmosphere under pressure. The ion chromatography section includes a guard column, a separation column, and a detector. The suction pipe has an intake port positioned at a target site whose environment is to be analyzed. The impinger section is connected to the ion chromatography section so that the absorbent solution of the vessel directly enters the ion chromatography section. To promote the absorption of the atmosphere into the solution, the absorbent solution vessel may be in the form of an elongate diffusion scrubber having an outer cylindrical vessel and an inner tube made of a selective membrane.
