TECHNOLOGICAL CHAMBER WITH DEVICE FOR INJECTION OF GASEOUS FLUID MEDIUM Russian patent published in 2016 - IPC F26B9/06 F26B21/04 F24F9/00 

FIELD: technological processes.

SUBSTANCE: invention relates to drying car bodies that are freshly painted or coated with anticorrosion protection. Process chamber (5) has internal space (39) with receiving area (15) for workpieces (3) in form of a tunnel with opening (12, 14) for input or output workpieces (3) and with device (17, 19, 25, 29, 33, 37, 35) for injection of gaseous medium, having at least one slotted nozzle (17, 19) or slit-like throttle diaphragm to create barrier (21, 23) between opening (12, 14) and receiving area (15) for workpieces (3). According to invention, slotted nozzle (17, 19) or slot-like throttling diaphragm feed gaseous medium through cover (6) into inner space (39) in an inclined relative to bottom (41) flow direction along guide path (211), which together with wall of input of a gateway (11) or output gateway (13) limits located above opening (12, 14) with an offset upwards relative to overlap (6) of mixing chamber. Invention also discloses a drying installation and/or hardening installation and/or painting installation equipped with process chamber (5), and a method of operating process chamber (5) with inner space.

EFFECT: invention must provide thermal separation of inner space of environment.
