VACUUM SEPARATOR COOLING METHOD AND APPARATUS Russian patent published in 2002 - IPC

FIELD: non-ferrous metallurgy, in particular, cooling of spongy titanium vacuum separator. SUBSTANCE: method involves placing spongy titanium vacuum separator into vessel; supplying cooling liquid; cooling vacuum separator and producing steam; discharging water in lower part of vessel and steam in upper part of vessel. Cooling is conducted in two stages: initially with simultaneous supplying of water and air in counterflow, with water being supplied from the top to the bottom so that water flows over vessel internal surface and air being supplied from the bottom to the top into space between vacuum separator and vessel wall, with following supplying of air while continuously discharging steam and air mixture. Second cooling stage is initiated, when vessel wall temperature is below 80 C. Apparatus has separator mounted in vessel made in the form of cylinder with conical lower part, water inlet branch pipe, steam and air discharge branch pipe in lower part and water discharge branch pipe located in vessel conical part. Apparatus is further equipped with baffling nozzles mounted on cylindrical part of vessel below steam and air discharge branch pipe circumferentially of cylinder. Nozzles are provided with plates rigidly welded at an angle of 30-45 deg to inlet opening of water inlet branch pipe, and with air inlet branch pipe located in lower cylindrical part of vessel. EFFECT: increased efficiency and simplified method and construction. 5 cl, 1 dwg
