A particle agglomeration system for improving filtering capacity of an HVAC system is disclosed. The system may include a first plate. The first plate may include a first sound generator. The system may include a second plate. The second plate may include a second sound generator. The system may include a frame. The frame may be configured to position the first plate relative to the second plate. A standing sound wave may be formable between the first sound generator and the second sound generator.

Pyrolysis systems and methods of generating hydrogen gas from a hydrocarbon gas. The pyrolysis systems include a solar thermal reactor configured to heat a gaseous hydrocarbon stream, such as methane, to its dissociation temperature. A supersonic turbomachine disposed in a housing receives resulting carbon particles and hydrogen gas from the solar thermal reactor and prevents dissociated carbon from forming deposits on an interior wall of the housing. A particulate separator is located downstream of the supersonic turbomachine to separate the carbon particles from the remaining hydrogen gas.

In one embodiment, a method for decreasing a humidity level in an information handling system includes: receiving, by a sound field chamber, an incoming airflow, the incoming airflow having a humidity level corresponding to an amount of water vapor in the incoming airflow; identifying, by a humidity controller, the humidity level of the incoming airflow; determining, by the humidity controller, that the humidity level is greater than a threshold humidity level; and in response to determining that the humidity level is greater than the threshold humidity level: causing, by the humidity controller, a sound source of the information handling system to generate a sound field within the sound field chamber, the sound field comprised of sound waves, the sound waves causing an acoustic agglomeration of the water vapor, the acoustic agglomeration causing the humidity level to decrease.

A gas compressor apparatus including a liquid-injected gas compressor device having a compressor inlet for receiving a gas and a compressor outlet through which a compressed gas stream flows, the compressed gas stream having liquid droplets therein, and a separator device communicating with the compressor outlet for receiving the gas stream for separating the liquid droplets from the gas stream, the separator device includes two liquid separators arranged in series and configured to allow the gas stream to flow in a connecting element from a separator outlet of the first liquid separator to a separator inlet of the second liquid separator, and means provided on or in the connecting element for creating radial standing waves in the gas stream to cause the liquid droplets therein to fuse together into larger liquid droplets.

An apparatus includes a chamber and an intake device configured to control a flow of fluid into the chamber. The fluid comprises particles; a resonance device is configured to resonate the chamber to provide an acoustic standing wave within the chambers. The frequency of the standing wave is selected to cause particles above a specific size to collect at a node of the standing wave.

In one embodiment, a dust collecting apparatus includes a container configured to contain a fluid that includes particles to be collected. The apparatus further includes one or more sound sources configured to generate, in the container, a standing sound wave including at least one node to trap the particles in a vicinity of the node. The one or more sound sources are configured to generate the standing sound wave so that the node does not contact a wall face of the container or contacts a predetermined portion of the wall face of the container. The predetermined portion is formed of a member that prevents the particles from leaving from the node located in a vicinity of the predetermined portion.

An aggregating device for separating solid material particles and fibers from liquid materials, and/or separating solid material particles and fibers from aerosols. The aggregating device includes i) a conveying means selected from a group consisting of a conveyor belt, a liquid pressure, a liquid column and a liquid wave of the liquid material, a centrifugal force, a centripetal force, an injector, a venturi device, a diffuser, a ducted turbine, a delta wing concentrator, an annular venturi device, a magnus effect turbine, a passive and active convection, effusion and diffusion, for receiving and/or conveying an aerosol and/or a liquid material in the conveying direction into the aggregating device, ii) an exciter for generating an acoustic sound wave which impinges upon the aerosol and/or the liquid material, and iii) a means for separating condensed liquids and/or aggregated solid materials from the aerosol and/or the liquid material.

This disclosure relates to aggregating, neutralizing, and filtering ultra-fine particles in fluids such as air and water. Fluid may be drawn from an ambient environment into a neutralization chamber. Within the neutralization chamber, particles in the fluid may be agglomerated. An acoustic field may be applied to the fluid to agglomerate the particles. The agglomerated particles may be exposed to light. The light may denature or deactivate the agglomerated particles. The agglomerated and inert particles maybe passed through a filter. After agglomeration and neutralization, the fluid may be released back into the ambient environment.

A particle control method is provided which can prevent an extremely small quantity of particles descending on a stream of a laminar flow in a clean zone through which the laminar flow flows as in a RABS or isolator device from descending to a specific position or can guide it so as to descend to the specific position by controlling movement of the particles. A particle descent position is separated away from a board surface of the oscillation board by using an acoustic radiation pressure generated by prompting ultrasonic vibration of the oscillation board disposed with a board surface substantially in parallel with a flow direction of the laminar flow.
