FIELD: production of sorbent on base of thermally expanded graphite used for extraction of water-insoluble compounds from water, soil and hard surfaces; gathering concentrated acids.
SUBSTANCE: proposed plant includes loading bin, proportioner, branch pipe for delivery of carrier gas, branch pipe for delivery of starting raw material (oxidized graphite), expansion chamber, separator with vertical partition and receiving bin. Proposed plant is also provided with ejector and tangential flow swirler combined with it; branch pipe for delivery of starting raw material is provided with external envelope for passing the coolant; ejector is mounted at expansion chamber inlet under outlet hole of starting material delivery branch pipe.
EFFECT: reduced power requirements with no reduction in productivity; improved quality of sorbent.
