Abstract: A heat exchanger which is particularly suitable for use in a process water distillation system comprises a first flow path configured to be flown through with a first fluid to be heated und a second flow path configured to be flown through with a second fluid to be cooled. The second flow path is in thermal contact with the first flow path at least in sections, and the second flow path is designed such that a flow of the second fluid, upon being fed into the second flow path and/or upon flowing through the second flow path, is calmed. A suction device is configured to suck a fluid component, which separates from the second fluid while the second fluid is supplied into the second flow path and/or flows through the second flow path, from a surface of the second fluid in the second flow path.

Abstract: A process water distillation system (10) comprises an evaporator (18), a condenser (34), a compressor (28) configured to generate a desired pressure in at least a region of the process water distillation system (10) and to convey steam from the evaporator (18) to the condenser (34) during operation of the process water distillation system (10), an inert gas source (40) configured to supply inert gas to the process water distillation system (10), and a control device (48) configured to control the supply of inert gas from the inert gas source (40) to the process water distillation system (10) in such a way that, at least in certain operating phases of the process water distillation system (10), an oxygen concentration in the process water distillation system (10) does not exceed a permissible maximum value.

Abstract: Apparatus for filtering solid particles suspended in a gas includes a housing divided by a plate into an upper clean gas chamber and a lower polluted gas chamber. Depending filter elements are secured to apertures in the plate. Polluted gas flows to a distributor, in the lower chamber below the filter elements, to which is coupled a plurality of vertically disposed pipes extending upwardly past the filter elements to outlets disposed in the vicinity of the plate. The upward discharge from these outlets is then deflected downwardly past the filter elements.

Abstract: An air-cooled vane-cell compressor is provided which has a housing, a bore hole therethrough and an outer surface. Cooling air fins are arranged on the housing surface in a longitudinal direction of the housing. A rotor which has two free shaft ends is arranged within the housing eccentric to the housing bore. Covers are arranged on front faces of the housing and the rotor shaft ends are rotatably supported in the covers. A suction flange and an ejection flange are arranged in the housing at 90.degree. to the covers and along a common longitudinal axis. The rotor has a rotational axis that is symmetrically arranged to the outer contour of the housing and to the flanges, and the housing bore is doubly eccentric to the rotational axis of the rotor in a top dead center direction.

Abstract: A single-stage vane compressor is provided which includes a casing that has a bore hole running from one end to another end, an outer contour, a water-cooled jacket, a rotor eccentrically arranged in the casing borehole and a rotational axis symmetric with the outer contour of the casing. The rotor has a top dead center position and a bottom dead center position, and the bore hole is arranged in the casing so as to be eccentric to the rotor axis toward the top dead center. A suction flange and an ejection flange are arranged opposite one another in the casing jacket along a common axis normal to the rotor axis, which common axis forms an axis of symmetry with the outer contour of the casing. Two axially parallel walls are arranged in the jacket in a vertical plane of symmetry so as to divide the cooling jacket relative to a suction side and an ejection side. Additionally, two water-cooled covers are provided, one of the covers being arranged on each end of the casing so as to cover the bore hole.
