摘要:
Die Erfindung betrifft einen Wärmetauscher mit zumindest einem Außenrohr (1), einem Mittelrohr (2) und einem länglichen Innenkörper (3), wobei der Innenkörper (3) im Inneren des Mittelrohrs (2) angeordnet ist und sich über zumindest einen Teil der Länge des Mittelrohrs (2) erstreckt und das Mittelrohr (2) im Inneren des Außenrohrs (1) angeordnet ist und sich das Mittelrohr (2) über zumindest einen Teil der Länge des Außenrohrs (1) erstreckt. Aufgabe der vorliegenden Erfindung ist damit, einen Wärmetauscher bereitzustellen, der eine geringe Anfälligkeit auf Verstopfungen aufweist. Dies wird dadurch gelöst, dass zumindest in einem inneren Zwischenraum (5) zwischen Innenkörper (3) und Mittelrohr (2) oder in einem äußeren Zwischenraum (4) zwischen Mittelrohr (2) und Außenrohr (1) zumindest eine Reinigungslippe angeordnet ist, und dass das Mittelrohr (2) in Bezug zum Innenkörper (3) und/oder zum Außenrohr (1) drehbar ist.

Counter-current air heat exchanger (20, 30, 40, 50, 60) comprising an outer tube (11, 13, 21, 31, 41, 51, 61) for a first air current and an inner tube (12, 22, 32, 42, 52, 62) for a counter-directed second air current, which inner tube is placed inside the outer tube, the inner tube being placed at a distance to the outer tube, which distance is defined by resilient spacer means (14, 23, 33, 43, 53, 63) placed and attached only to and along the outer surface of the inner tube so that the inner tube together with the spacer means can both be axially displaced and rotated in relation to the outer tube without the tubes upon said movement being brought in contact with each other.

The invention relates to a device for cleaning the outer surface of a pipe (4) having a longitudinal axis. The device (1) has a frame (2) having driving means and press-on means (8, 9) for the longitudinally directed motion of the device (1) on the outer surface of the pipe (4) and a runner (3), which has a longitudinally directed passage for feeding the pipe (4) through and is rotatably fastened to the frame (3) about the longitudinal axis of the pipe (4), wherein the runner (3) carries cleaning elements (31), which are in contact with the outer surface of the pipe (4) when the device (1) is operating.
摘要:
A tube cleaning assembly (10) comprising a cylindrical housing (11) having a bore (20) with a coaxial strut (27) therein, capable of both axial and rotation movement relative to the housing (11). One end of the strut (27) extends through an aperture, (29) in an end wall (21) of the housing (11) and is connected to a cleaning brush (17), the other end of the strut (27) being adjacent a piston (26) reciprocable within the bore (11) to move the strut axially, the axial movement of the strut (27) being translated into rotational movement around its axis and rotating both strut and brush.
摘要:
The water turbine provided by the present invention comprises a rotor (3) which forms a rotor blade (10) on one end and is bored with an exhaust liquid channel (4) on the center of the axis to open to the center of the rotor blade, an inner casing (5) which is bored with a nozzle (6) on the circumference thereof and which supports said rotor in a manner to surround the rotor blade of the rotor and an outer casing (7) having a liquid inlet port (9) which defines a pressure chamber with the inner casing, and can be made so compact as to be held in a hand. The brush head (21) for the pipe cleaning device which utilizes the water turbine as a driving source is so constructed that a brush (20) is formed on an end of the rotor of the water turbine wherein the dirts or scales adhered to the inner surface of a pipe are peeled off with a rapidly revolving brush and then washed away with the pressurized liquid which has been used for revolving the water turbine.
摘要:
A waste heat recovery apparatus comprising a high-temperature unit (1) including a high-temperature casing having an inlet through which an exhaust gas is introduced into the unit and an outlet through which the exhaust gas is discharged from the unit, a set of heat exchanger tubes (6) arranged in the high-temperature casing, and a dry-type cleaner (7) for removing dust on the heat exchanger tubes, a low-temperature unit (2) including a low-temperature casing having an inlet through which the exhaust gas is introduced into the unit and an outlet through which the exhaust gas is discharged from the unit, a set of heat exchanger tubes (6) arranged in the low-temperature casing, and a flush-type cleaner (8) for removing dust on the heat exchanger tubes by spraying flushing water on the tubes, an intermediate duct (3) connecting the outlet of the high-temperature unit (1) and the inlet of the low-temperature unit (2) so that the exhaust gas from the high-temperature unit is passed into the low-temperature unit through the intermediate duct, an exhaust duct (5) connected to the outlet of the low-temperature unit so that the exhaust gas is discharged from the low-temperature unit through the exhaust duct, a by-pass duct (10) connecting the intermediate duct and the exhaust duct, first damper (9) for controlling the flow of the exhaust gas from the intermediate duct to the low-temperature casing, and second damper (11) for controlling the flow of the exhaust gas from the intermediate duct to the by-pass duct.
