    Abstract: Apparatus for treating a fluid having an ioniser (1) with one or more outlets connected to a chamber (7) having one or more inlets and one or more outlets. The chamber has a maximum cross-section transverse to a direction of flow between the/or each inlet and the/or each outlet and the cross-section of the/or each outlet is smaller than the maximum cross-section. A gas flow means is arranged, in use, to cause a gas to flow via the ioniser and the chamber and combine ionised gas with a fluid to be treated thereby to introduce hydroxyl radicals into the fluid, and so treat the fluid. Fluids, especially liquids containing water, are treated by the introduction of hydroxyl radicals generated by ionising a gas, especially air. The ioniser may be a dielectric barrier discharge device having a tubular dielectric (14) surrounding an electrode (15) and, in turn, surrounded by an electrically conductive sleeve (16), the ends of which may be flared, rounded or turned back. Air may be caused to flow through the device by a pump, blower or venturi device (9).

    Abstract: Plasma processing of powder particles is performed by supplying a first gas stream, containing particle material to be processed, and a second gas stream comprising a plasma carrier gas. The first gas stream is supplied from an inlet pipe into a dielectric pipe. The dielectric pipe coaxially surrounds the inlet pipe, and extends beyond a downstream end of the inlet pipe. The second gas stream is supplied into a space between the inlet pipe and the dielectric pipe and from there into the dielectric pipe beyond a downstream end of the inlet pipe. A surface dielectric barrier plasma discharge is generated along the inner surface of the dielectric pipe at least on a part of the dielectric pipe upstream of the downstream end of the inlet pipe.

    Abstract: A sterilization and decontamination system in which a non-thermal plasma discharge device is disposed upstream of a suspension media (e.g., a filter, electrostatic precipitator, carbon bed). The plasma discharge device generates a plasma that is emitted through apertures (e.g., capillaries or slits) in the primary dielectric. Plasma generated active sterilizing species when exposed to contaminants or undesirable particulate matter is able to deactivate or reduce such matter in contaminated fluid stream and/or on objects. Thus, the undesirable contaminants in the fluid to be treated are first reduced during their exposure to the plasma generated active sterilizing species in the plasma region of the discharge device. Furthermore, the plasma generated active sterilizing species are carried downstream to suspension media and upon contact therewith deactivate the contaminants collected on the suspension media itself. Advantageously, the suspension media may be cleansed in situ. To increase the sterilization efficicency an additive, free or carrier gas (e.g., alcohol, water, dry air) may be injected into the apertures defined in the primary dielectric. These additives increase the concentration of plasma generated active sterilizing agents while reducing the byproduct of generated undesirable ozone pollutants. Downstream of the filter the fluid stream may be further treated by being exposed to a catalyst media or additional suspension media to further reduce the amount of undesirable particulate matter.

    Abstract translation: 一种灭菌和去污系统,其中非热等离子体放电装置设置在悬浮介质(例如,过滤器,静电除尘器,碳床)的上游。 等离子体放电装置产生通过初级电介质中的孔(例如毛细管或狭缝)发射的等离子体。 当暴露于污染物或不期望的颗粒物质时,等离子体产生的活性灭菌物质能够使被污染的流体物流和/或物体上的物质失活或减少。 因此,待处理流体中的不期望的污染物在暴露于放电装置的等离子体区域中的等离子体产生的活性灭菌物质时首先被还原。 此外,等离子体产生的活性灭菌物质被运送到悬浮介质的下游,并且在与其接触时,使收集在悬浮介质本身上的污染物失活。 有利地,悬浮介质可以在原位清洁。 为了提高灭菌效率,可将添加剂,游离或载气(例如酒精,水,干燥空气)注入限定在初级电介质中的孔中。 这些添加剂增加等离子体生成的活性灭菌剂的浓度,同时减少产生的不期望的臭氧污染物的副产物。 在过滤器的下游,可以通过暴露于催化剂介质或另外的悬浮介质来进一步处理流体流,以进一步减少不期望的颗粒物质的量。
