摘要:
Bekannte Behälter zur Behandlung von Werkstücken oder von Materialien sehen Möglichkeiten zur induktiven Beheizung vor, wobei es sich bei diesen Behältern um offene Konstruktionen handelt. Bei manchen Prozessen, die üblicherweise im Durchlaufverfahren stattfinden, werden jedoch zu unterschiedlichen Zeiten verschiedene Prozessparameter benötigt. Die vorliegende Erfindung lässt diese Durchlaufverfahren energiesparend innerhalb der einzelnen Behälter ablaufen, so dass eine Erhitzung und Abkühlung, die Anpassung des Atmosphärendrucks, der Luftfeuchtigkeit und anderer Parameter, sowie zusätzlich die Kapselung gesundheitsgefährdender Stoffe in diesem Behälter ermöglicht werden. Dies gelingt durch einen hermetisch abdichtbaren und vakuumisolierten Behälter mit einer Zugangsöffnung zur Beschickung mit Werkstücken und Material.

Damage of a lining member is prevented through mitigation of stress concentration due to a difference in thermal expansion. A lining structure 1 of a lining member 20 is provided on a base material 10 of an insertion tube 3 used for adding a chemical to a reaction vessel 2 for leaching under high temperature and high pressure. The base material 10 has a tube section 11 and a flange section 12. The lining member 20 is provided on the base material 10 and formed of a material different from that of the base material 10, and has a tube section lining section 21 provided on the tube section 11 and a flange lining section 22 provided on the flange section 12. A chamfer section 13 is formed on the flange section 12. The tube section lining section 21 is protruded to the same height as a flat surface 22a of the flange lining section 22. The flange lining section 22 has a curved surface section 24 protruded toward the base material 10 side on the chamfer section 13 and is welded to a protruding section of the tube section lining section 21 that protrudes from a slant surface 13a of the chamfer section 13.

A hydrothermal oxidation device for treating a material in a supercritical medium, comprises: a main body (2); an inner tube (8) placed inside the main body (2) so as to form an annular area (10) along the main body; a stirring means (14) placed in the inner area (12) of the inner tube and actuated by means of a rotating shaft; a cooling means (18) for cooling the treated material located in the inner area (12) of the inner tube (8); an inlet (32) for a mixture of water and oxidant; an outlet for effluents; and an inlet (16) for material to be treated, located at one end of the main body, said inlet opening into the inner tube (8). The oxidation device further comprises an inlet (26) for a diluted effluent, located in the flange (4) and connected to a preheating coil (28) arranged along the inner wall of the main body and extending from the first end thereof to the second end thereof, the preheating coil (28) opening into the inner tube (8).
摘要:
The present invention relates to a method and an arrangement for pressure and temperature let down of autoclave discharge slurry (106), in particular in pressure oxidation or high pressure acid leach of metal containing ore. The method of the invention comprises a step of providing autoclave vent gas (105) obtained from the autoclave (1) to the top-entry flash vessel (2) for inducing overpressure to the said top-entry flash vessel and preventing boiling of the slurry during the transfer to next top-entry flash vessel (3). The invention further relates to an autoclave and pressure let-down arrangement adapted for providing autoclave vent gas to one or more top-entry flash vessels.
