Device for injecting fluid under pressure into a heat exchanger plate and method of cleaning of such a device for injection

摘要

The invention has for its object a device for injecting fluid under pressure in a plate-type heat exchanger comprising a sealed enclosure (2) provided with means for feeding and removing a first fluid under pressure, a bundle of plates (1) disposed in said chamber (2) and having channels for circulation of the first fluid mixed with a second fluid under pressure, at least one pipe (21) of the injection of the second fluid, characterized in that the pipe (21) is connected to a pipe (22) of supply of the second fluid and to a pipe (24) for discharging the particles deposited on a filter member disposed inside the tube (21) downstream of the connection of said pipe (22, 24) on said tube (21) with respect to the direction of circulation of the second may incorporate additional invention also relates to a process for cleaning such an injection device.
