摘要： A compact electrostatic precipitator is designed specifically for use in connection with eliminating particles from crankcase emissions of a Diesel engine. Such emissions may carry solid soot particles as well as suspended oil droplets. The electrostatic precipitator has an electrode housing in which a high voltage electrode is mounted, and the emissions from the crankcase of a Diesel engine are passed across the electrode to an outlet. A high voltage power supply is mounted in a separate housing, and the output of the high voltage power supply is connected to the electrode only when the electrode housing and the power supply housing are properly mated, to thereby disable the high voltage connection to the electrode when the power supply housing is removed. A current limiting device is used in the circuit to the power supply to prevent high currents from being carried if any arcing occurs, and a normally open switch is closed to provide input power to the high voltage circuitry only when the power supply housing and the electrode housing are mated.

摘要： An atomizer has a chamber holding a liquid containing particles of a desired material. Aerosol particles are formed by using an aspirating nozzle or ultrasonic vibrator and the aerosol particles are carried in a gas flow. The aerosol particles are treated by increasing the charge on the aerosol particles by contact with a high voltage electrode and the aerosol particles are passed through inertial separator stages to remove large aerosol particles from the flow so they are not discharged from the atomizer.

摘要： An apparatus for handling exhaust gases, such as diesel exhaust, which cools the exhaust gases as the gases exit a diesel engine, and then filters such gases to remove particulate material. A housing has an inlet pipe with perforations and a filling of a liquid through which gas bubbles as it exits the perforations in the inlet pipe. The gas bubbling through the liquid cools the gases. In order to maintain the bubbles at a desired size, a perforated or porous layer of material is provided in the liquid so that gas moves through the perforated layer before it exits the liquid. Preferably the gas exiting the liquid is then passed through a filter which is maintained in a wet condition by mist carried by the gases that is formed as the gases burst through the surface of the liquid. The fibers of the filter are maintained wetted so that particles of material do not adhere to the fibers and can be flushed therefrom.

摘要： A particle removal system provides for the removal of submicron particles in gas streams, such as combustion flue gases or diesel exhausts. The gas stream is treated to permit very fine particles to coagulate through a short residence time in the conduits handling the gas stream, and thereafter is conditioned to establish saturation of the gas stream at a low temperature, such as by water injection. The saturated stream of gas containing the particles is then passed through a particle growth chamber or section where steam is injected into the gas to establish a supersaturation condition, causing the particles in the gas stream to grow in size by water condensing around the particles. The particles are grown to a size that is near one micron, and are removed through conventional particulate removal devices.

摘要： The method and apparatus for controlling particulate emissions from a combustion apparatus, as a diesel engine. Diesel engine exhaust particles are electrically charged during the formation of the particles in the engine combustion chamber. A particle collector is used to collect the electrically charged particles on collecting structures connected to a high voltage power supply and ground. The collecting structures of the particle collector can be a plurality of parallel metal plates, spaced cylindrical rods, or concentrically located cylindrical members. A fibrous matrix can be located adjacent the particle collecting structure to collect the charged particles as they move through the matrix. In one embodiment, the collected particles separate from the collecting structures and return to the engine intake. In another embodiment, a removable collecting cartridge has electrically conductive plates for collecting the charged particles. The entire cartridge is removed for cleaning or replacement. The hot exhaust gas from the engine can be used to oxidize the collected particles. The collected particles that are not oxidized can be separated from the collecting structures and re-entrained into the gas. The re-entrained particles are larger than the particles formed in the combustion apparatus. The large particles can be removed by a downstream particle collection device or mixed with fuel for the engine.

摘要： A method for establishing a calibrating standard for wafer inspection includes depositing solid ionized particles of a known size range with an aerosol onto a wafer. The method also includes depositing particles onto a wafer in a deposition chamber by using an aerosol stream and the solid particles suspended in a gas; ionizing the aerosol stream with a negative or positive charge polarity or both by passing the aerosol stream through a non-radioactive ionizer to produce charged particles and supplying such aerosol stream to the deposition chamber. An apparatus for producing charged particles includes an atomizer and a non-radioactive ionizer in fluid communication with each other. The apparatus may also include an electrospray droplet generator for producing an aerosol with dry-solid particles and an ionizer that ionizes the molecules of the gas. The apparatus may also include a generator for generating an aerosol with particles suspended in the gas with a non-radioactive ionizer that ionizes the gas in the aerosol causing the aerosol particles to be charged. The apparatus may further include an electrostatic classifier for classifying the charged particles to a selected size range.

摘要： The present disclosure has an apparatus for detecting fibers in a gas flowing along a passageway. A laser beam is provided at one end of the passageway and the beam is directed along a length of the passageway through which the gas flows. An electrode system, as disclosed, a quadrupole electrode system is mounted along the passageway to cause fibers carried in the gas to oscillate in a detection zone. A photo detector is positioned laterally of the passageway and detects light scattered by the oscillating fibers and projected through an opening in the passageway to provide an output signal that is a function of the light scattered by the fibers in the detection zone.
