摘要： An appartus for removing VOC from a plurality of remotely located sources of VOC contaminated gas streams includes a plurality of liquid absorbers, each located near and communicating with a source of a VOC contaminated gas stream, the liquid absorbers associating the VOC with a scrubbing liquid. A conduit is connected to each liquid absorber for conveying VOC laden scrubbing liquid from the liquid absorber to a separating apparatus in fluid communication with each of the conduits. The separating apparatus receives the VOC laden scrubbing liquid from the plurality of liquid absorbers and separates the VOC from the scrubbing liquid. A conduit recycles the scrubbing liquid from the separating apparatus to at least one of the plurality of liquid absorbers. A method for removing VOC from a plurality of remotely located sources of gas streams contaminated with VOC includes contacting each VOC contaminated gas stream with a scrubbing liquid close to the VOC containing gas stream source to associate the VOC with the scrubbing liquid. The VOC laden scrubbing liquid from the various sources is conveyed to a single separator and the VOC is separated from the scrubbing liquid at the separator.

摘要： An exhaust gas treatment apparatus for treating exhaust gas generated in semiconductor manufacturing processes. It includes a main pipe, a gas vortex means, a water vortex means, an U pipe and a discharge pipe. The main pipe transforms the exhaust gases to waste powder which are discharged out through the U pipe and the discharge pipe. The gas vortex means and water vortex means are located below the main pipe for generating annular and even downward gas flow and water flow at the outlet of the main pipe for preventing reflux of waste powder from entering into the main pipe. Waste powder thus won't deposit around the outlet. Scraper in the main pipe won't be stuck or deformed. Waste powder may be discharged out through the U pipe and discharge pipe smoothly and efficiently.
摘要翻译：一种用于处理在半导体制造工艺中产生的废气的排气处理装置。它包括主管，气体涡流装置，水涡流装置，U型管和排放管。主管将废气转换成通过U管和排放管排出的废粉。气体涡流装置和水涡流装置位于主管下方，用于在主管出口处产生环形和均匀的向下气流和水流，以防止废粉回流进入主管。因此，废粉不会在出口附近沉积。主管中的刮刀不会卡住或变形。废粉可以通过U型管和排水管顺畅，高效地排出。
