DEVICE FOR DEGASSING OF LIQUID MEDIA Russian patent published in 2021 - IPC C02F1/20 B01D19/00 

FIELD: mining; chemistry.

SUBSTANCE: invention relates to installations for degassing of various liquid media, including suspensions and emulsions under vacuum, and can be used in mining, food, chemical and other industries. Design features of the degasser are obtained by forming and investigating a mathematical model, by means of which the profile of the liquid velocity at the output of the degassing degasifier inlet is reproduced considering the diameter of the degasser cylindrical housing. Based on the obtained data, a relationship is found between the distance required for gas bubbles to enter a vortex air cord, and their dimensions, which made it possible to design degasifier with possibility of deformation and enlargement of gas bubbles at their merging and at the same time crushing of remaining gas bubbles not included into air cord.

EFFECT: technical result achieved when using the claimed invention consists in enabling degassing of liquids with large volume fraction of gases (more than 10 %) and large bubbles (size of more than 0.5 mm) due to the stability of the air vortex cord formed in the degasifier.
