FIELD: chemical engineering. SUBSTANCE: arrangement has a foundation in the form of sheet with figured through openings closed by valve contact plates provided with guides, their rise being limited with stops. The plates, in contrast to prototype, correspond to openings in the foundation sheet and are rigidly secured to guides made in the form of balance weight and additionally provided with valve drop stops. Contact plates may also be made from cut pieces formed when foundation sheet has been slotted. Guides for each valve are lap-joined with valve plates to form reliable clearance between contact plate and dish cloth. EFFECT: improved design. 3 cl, 4 dwg
