Abstract: A wet cyclone particle collector is disclosed. The wet cyclone particle collector includes a cyclone unit, a liquid delivery unit and a sample collection unit. The cyclone unit draws a gas sample into a cyclone chamber and creates a circular flow of the gas sample inside the cyclone chamber so that particles in the gas sample are separated from said gas sample by centrifugation force. The liquid delivery unit delivers a collection liquid into the cyclone in a non-continuous fashion. The sample collection unit harvests the collection liquid from the cyclone unit. The non-continuous delivery of the collection liquid significantly reduces consumption of collection liquid during operation of the particle collector.

Abstract: A dust collector (10) has a main body (12), the interior of which is divided by a tubular partition wall (26) into a central filtration chamber (30) and an outwardly-located annular cyclone chamber (32). At the upper part of the cyclone chamber (32), there is provided a water supply pipe (36) having radially directed nozzles (38) adapted to form a water film flowing down along the inner circumferential surface of the main body (12) and the-outer circumferential surface of the partition wall (26), respectively. Air to be treated is drawn under suction through an air intake (34) into the cyclone chamber (32) and swirling air is brought into contact with the water film whereby dust and particles are preliminarily collected while retaining an explosion-proof function. The cyclone chamber (32) and the filtration chamber (30) are communicated with each other at the lower portion thereof to permit the thus pretreated air to be drawn into the filtration chamber (30).

Abstract: A novel stack application for improved carbon dioxide and particle removal/collection from flue gases produced during coal power-generation processes. Flue gas tangential inlet velocity is increased to subject upward-flowing flue gas in a stack to a centrifugal force, thereby propelling entrained solid particles and CO2 in the flue gas to the stack wall for collection. Collection efficiency is further improved by a cascading water film or algae-laden water film on the inside of the stack wall and on surfaces of an optional internally mounted vortex generator to eliminate the re-entrainment of small particles and for ease of transporting the captured particles in a slurry. The stack can also be utilized as a photochemical or a biological reactor to promote a photosynthesis reaction between carbon dioxide and algae-laden water to form carbohydrate substrates for carbon dioxide sequestration and utilization.

A plurality of non-linear conduits having a plurality of fluid spraying nozzles provides thorough mixing between air and fluid to maximize the removal of particulates from the air. The fluid circulates continuously from a reservoir through the nozzles and conduits back to the reservoir. Simple fluids, such as water, are preferably used, although disinfectants, deodorants and/or scents may be added to the fluid.

Abstract: The particle separation and collection assembly uses cyclonic forces to separate and remove large particles from an airstream and concentrate small particles for sensor/detector technology. This assembly utilizes multiple mini cyclones operating in parallel to reduce the size and velocity of air through the cyclone inlets while maintaining the same fluid or flow rate as compared to one large cyclone. The multiple cyclone system can be arranged in a radial geometry or in a bipolar or uni-polar longitudinal design. The particle separator and collection assembly uses a blower or vacuum pump to draw outside gas into the cyclone particle separator assembly through radial inlets. Vacuum transfer channels, extending the entire length of the assembly, pull gas into the top of the cyclone chambers and out through the bottom apex of cyclone chamber and through the top vortex finder.

Abstract: The present invention is a method for removing particulate matter and aerosols from a gas stream generated by gasification prior to the gas stream being used as fuel in an internal combustion device or as synthesis gas for subsequent processing. The present invention consists of first cooling the gas stream, then oil scrubbing it to further cool it and to remove particulates and some tars, and finally passing the gas stream through one or more vortex chambers to remove additional tars. Each vortex chamber employs a high-speed fan that forces the tar droplets against the interior wall of the vortex chamber where the tar coalesces and is removed.

Particulate matter contained in the gas flow is deposited in the liquid on the second surface of the porous wall. A virtual impactor may be used with the system for concentrating the particulate matter contained in the gas flow.
