Abstract (en)
[origin: EP0877222A2] The pressurised fluid injection device is for plate heat exchanger comprising a sealed enclosure (2) having inlet and exhaust for a first pressurised fluid. A plate bundle (1) located in the enclosure is composed of a plate stack (10) having flow channels between them for a first fluid mixed with a second pressurised fluid and for a heat conducting fluid. An injection tube (21) for the second fluid has calibrated orifices (26) and extends over the whole width of the plate bundle. The injection tube has a closed (21a) end and open (21b) end connected to a supply pipe (22) of the second fluid provided with a shut off valve (23). The open end is also connected to a pipe (24) for evacuating the particles deposited on a filter placed inside the tube upstream of the branching of the two pipes (22,24). The evacuation tube has a shut off valve (25).
