Abstract (en)
[origin: WO2016189184A1] An arrangement for keeping a plate heat exchanger clean in cooling of gas (G1) is characterised in that for carrying out a cleaning action in one or more slots (S7, S8) between the plates (3) it comprises in the inlet channel (6) movable first means (17, 20) for forming a block (38, 39) between said slots (S7, S8) and the inlet channel and opening a connection (18, 20) from said slots to a space having negative pressure in relation to the pressure in the heat exchanger for generating an instantaneous discharge (G3) of gas and cleaning blast from said slots and respectively closing said connection and opening said block, and additionally second means for controlling moving of the first means and the cleaning action.
