摘要： An air-inlet duct includes a particle separator and an agglomerator. The particle separator is configured to receive atmospheric air laden with particles and to direct the particles into a scavenge passageway while allowing the atmospheric air to move into a compressor passageway thereby reducing the number of particles that enter the compressor passageway. The agglomerator is configured to cause the particles to be attracted to one another and cluster together.

摘要： An emissions reduction stack includes a conditioning section, collector section utilizing a Wet Electrostatic Precipitator (WESP), and output section. A chemically active aqueous stream is introduced into an incoming process stream in order to saturate the stream and produce a fog stream wherein water is condensed on the surface of particulates. The process of condensation increases the efficiency of the particulate filtration process conducted by the WESP.

摘要： Fly ash and fine dust in a gas stream from a coal combustor, for example, are efficiently collected in a 2-stage, tubular, granular bed filter. The stages of the filter are arranged one above the other so that the granules may move from the upper stage to the lower stage under the influence of gravity. Larger particulate in the gas stream is first collected by the lower stage, and then the remaining particulate is electrically charged and collected by the upper stage. Both stages are electrified sufficiently to rigidify the granular beds and adhere the particulate to the granules, so that the granules and the collected particulate move downwardly through the filters as a plug. Granules that exit from the lower stage are cleaned and returned to the upper stage. Non-porous granules may be used to prevent fine particulate from becoming embedded in the granules.
摘要翻译：例如，来自煤燃烧器的气流中的飞灰和细粉尘被有效地收集在两级管状颗粒床式过滤器中。过滤器的阶段彼此上下布置，使得颗粒可以在重力的作用下从上层移动到下层。气流中的较大颗粒首先由下段收集，然后将剩余的颗粒带电并由上段收集。两个阶段充分充电以使颗粒床硬化并将颗粒粘附到颗粒上，使得颗粒和收集的颗粒作为塞子向下移动通过过滤器。从下层出来的颗粒被清洗并返回到上层。可以使用无孔颗粒来防止细颗粒嵌入颗粒中。

摘要： A particle size distribution measuring system 1 sets a reference voltage in a DMA 300 to a voltage value U, and executes the classifying of aerosol particles based on electrical mobility, in an electric field to which the voltage value U is supplied. When a predetermined condition is not satisfied, an analyzing device 600 causes a sum of the voltage value for the previous classifying (previous value) and the voltage value U to be re-set in the DMA 300 and causes the classifying of the aerosol particles to be executed again. A particle measuring device 400 defines a first measurement result as a measurement result M1, and defines a result of the re-measurement as a new measurement result Mx every time the measurement is thereafter repeated. An analyzing device 600 calculates a ratio of the measurement result Mx to the measurement result M1, and confirms that the condition is satisfied when the calculation result is a prescribed value or smaller, while confirming that the condition is not satisfied when the calculation result is larger than the prescribed value.

摘要： The invention relates to apparatus for biological purification and filtration of air. The apparatus includes a coarse filter (1), an ionizer (5), an additional plate (9) and a fine filter (10), which are installed in this order along the path of the gas flow, and a power source (23). The coarse filter (1) is essentially an electrostatic precipitator consisting of three plates (2,3,4) adjacent to each other, the outer-most (2,3) of which are made of a cellular metal and are connected electrically to the opposite-in-sign terminals of the power source (23), whereas the central plate (4) is made of polyurethane foam. The coarse filter (1) abuts closely on the cylindrical nondischarge electrode (6) of the ionizer (5).
