A method for cleaning a plate heat exchanger, which plate heat exchanger comprises
- a plate pack formed of circular heat exchange plates having openings and being arranged on top of each other, the height of which pack defines a longitudinal direction of the plate pack, and which plate pack comprises ends in the direction of the heat exchange plates and an outer surface defined by the outer edges of the heat exchange plates, and in which plate pack the heat exchange plates are attached to each other alternately at the openings of the plates and at the perimeters of the plates, and
- an outer casing surrounding the plate pack, which casing comprises end plates mainly in the direction of the ends of the plate pack and a shell connecting the end plates, of which end plates at least one is arranged to be openable, wherein the method comprises at least the following steps
- opening at least one end plate of the outer casing,
- removing the plate pack from the outer casing,
- fixing the plate pack to a support base,
- arranging a support mechanism into the plate pack in order to stretch the plate pack evenly in the whole length of the plate pack,
- stretching the plate pack in its longitudinal direction so that the spaces between the plates of the plate pack increase, and
- cleaning the plate spaces of the plate pack.
