摘要： An electrically resistive flocculating agent is added to electrically conductive solid fines recovered from an electrofiltration zone. The dry flocculated solid fines including the flocculating agent are recycled to the electrofiltration zone in which a gaseous mixture containing fines is contacted with an electrically enhanced mass of solid contact particles.

摘要： The invention relates to a portable air cleaner unit which includes a casing having an air inlet and an outlet and defining an air cleaning path between the inlet and outlet. A prefilter is disposed downstream of the air inlet and a main filter is disposed downstream of the prefilter. An air mover such as a fan is disposed downstream of the main filter, and an exposed negative ion source is disposed downstream of the fan on the external surface of the air outlet. In accordance with the invention, the main filter consists of fibers shredded from a non-carcinogenic plastic membrane which has been permanently electrostatically charged. The negative ion source ionizes the cleaned air as it leaves the cabinet.

摘要： Coal gas produced in an iron bath reactor during the gasification of coal is first cooled down in a first cooling step to a temperature of, preferably, 300.degree. C., and is subsequently purified at this temperature in a first electrofilter, then cooled down in a second cooling step to a temperature of, preferably 50.degree. C. and, finally, purified at this temperature in a second electrofilter.

摘要： Disclosed herein is a method for removing airborne particulates from an aerosol stream by first humidifying said aerosol with steam, and then cooling said aerosol with water to saturation temperature. Thereafter, the saturated aerosol is adiabatically cooled to a supersaturated state and maintained at supersaturation for a time sufficient to permit the growth and removal thereof of said particulates. Further disclosed is an apparatus adapted for practicing the method of the present invention and employing charged droplet scrubbing techniques to remove said particulates.

摘要： An oil mist and solid particle laden gas from an oil shale retorting operation is initially treated with a temperature controlled oil spray and then by a coalescer to reduce the quantity of oil mist and remove most of the solid particle content of the gas stream and then finally treated by an electrostatic precipitator to essentially remove the oil mist remaining in the gas.

摘要： A horizontal-flow electrostatic filter for gas passing from a boiler to a chimney and having separate flow chambers lying horizontally side-by-side has inlet and outlet ducting arranged such that flue gases are divided to flow in opposite directions through the respective chambers, both directions of flow being at right angles to the direction of the shortest distance between the boiler house and the chimney. The flue gas output of the boiler is divided equally between the chambers. The size and hence capacity of the filter may be greater, in this disposition, for a given said distance than if a prior art parallel co-current flow arrangement (shown in FIG. 1 of the drawings) were used. Capacity for a given available floor space is further assisted by providing a plurality of arrays of collection and discharge electrodes separately electrically supplied and controlled.
