APPARATUS FOR CARRYING OUT PHYSICAL-CHEMICAL PROCESSES IN THE VORTEX GAS FLOW Russian patent published in 1995 - IPC

FIELD: chemical industry. SUBSTANCE: apparatus has housing 1. Plates 10 with vortex contact devices 5 are mounted along the height of the housing and have upper perforated 6 and lower 7 parts. The apparatus also has tangential tubes for introducing interacting agents 2 and for removing products of interaction 11, 12, 13 connecting the overlying plate with the underlying one and the underlying plate with the center of vortex contact device 5, and coaxial cylinder 14 with notches in the lower part. Shell 9 with the height equal to 0.7-1.0 of the distance between the bottom and the lower edge of the incision is disposed between the bottom of housing 1 and vortex contact device 5. Upper part 6 of contact device 5 is connected with the pipe for removing the products of interaction of the apparatus. In case this apparatus is used the duration of availability of both liquid and a hard phase at each step is increased 10-15 times. EFFECT: enhanced efficiency. 2 dwg, 1 tbl
