<p>The invention relates to the building material and binder industry and is used for producing high-strength alpha-semihydrate and alpha-anhydrite gypsum binders. The inventive device for hydrothermally treating and drying plaster stone comprises a working chamber-autoclave (1) provided with a hot heat-carrier supply system, a vacuum receiver (41), a vacuum pump (42), a gas-distributing manifolds and rapid-acting dampers (11, 13, 15, 17). Said plant also comprises an even number of gas- distributing segmental sections (3) which are symmetrically arranged with respect to the vertical axis of the working chamber and are separated from each other by a vertical tight partition (4), wherein vertical rectangular walls (5) separating the gas-distributing sections (3) from the service volume of the working chamber (1) are provided with a perforation increasing the flow through cross-section of gas windows from the top downward along the wall height. Each gas-distributing section (3) is connected to a gas-intake pipe (6) provided with an adjustable gas shut-off gate (7). All gas-intake pipes (6) are connected to symmetrical gas-distributing pipes (8) which are provided with adjustable gas gates (9) connected in the mid-length thereof to pipes (10) comprising rapid-acting dampers (11).</p> |
