METHOD OF SLUDGE DEHYDRATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2024 - IPC C02F11/14 C02F11/13 

FIELD: technological processes.

SUBSTANCE: group of inventions relates to dehydration of watered sludge. Liquid hydrocarbon agent, boiling point of which is higher than boiling point of water, and watered sludge sediment are introduced into the vessel. Ratio of weight of liquid hydrocarbon agent to weight of watered sludge is from 1:0.10 to 1:1.30. Said components are mixed with constant heating to obtain the specified final moisture content of the sludge. Stirring of said components and unloading of dehydrated sludge is carried out using an inclined screw mechanism, The latter can rotate towards mixing and discharge with simultaneous filtering of produced mix. Screw mechanism blade is made in the form of flat brush with arrangement of its pile radially from screw axis to periphery. Final moisture content of the sludge is controlled by means of a balance on which a heat-insulated casing of the vessel is installed.

EFFECT: reducing power consumption, simplifying the design of the device using one mechanism to perform several functions.
