    摘要： Apparatus for cleaning gas comprising a hollow outer vessel having an inner wall and a clean gas outlet communicating through the wall of the outer vessel with the interior of the outer vessel. An inner casing is attached to, supported by and within the outer vessel and has its vertical axis coincident with the vertical axis of the outer vessel. The inner casing is spaced from the inner wall of the outer vessel so as to form an annular space therebetween. Partition means is disposed within the inner casing sealingly dividing the inner casing into at least a pair of chambers. The first of these chambers has an opening therein communicating with the clean gas outlet of the outer vessel and a gas inlet operatively engages the second of these chambers for introducing gas burdened with particles into the second of these chambers. A plurality of centrifugal separators cooperates with the second of these chambers, each of these separators having an outer first tube with its upper end communicating with the interior of the second of these chambers. Particle and blowdown gas collecting means is located within the vessel and communicates with openings in the lower ends of the outer tubes of the separators. Each of the separators further includes a second tube mounted within each of the outer tubes having its upper end communicating with the interior of the second of the chambers. Swirl-producing means is located between the first and second tubes for producing a swirling motion to gas introduced within the first tubes and expandable structural means operatively engages the inner casing and is adapted to allow the inner casing to substantially expand and contract under apparatus operating conditions without damaging the structure of the outer vessel. A particle and blowdown gas outlet operatively engages the outer vessel and communicates with the particle and blowdown gas collection means for removing particles and blowdown gas from the apparatus.
