GAS-LIFT APPARATUS Russian patent published in 1998 - IPC

FIELD: devices for oxidation of complex solid-liquid suspensions, applicable in processing of small amounts of biogenic waste in the conditions of periodic process. SUBSTANCE: gas-lift apparatus has liquid and gas-separating chambers in the form of hollow cylinders located one above the other connected by gas-lift and circulation pipes with formation of a side circuit, gas feed pipe connection located in the lower part of the gas-lift pipe, source material feed and final product discharge pipes. For intensification of mixing and prevention of dead zones the lower end of the gas-lift pipe is positioned in the front part of the liquid chamber, and the upper end, in the back part of the gas-separating chamber; upper end of the circulation pipe is positioned in front part of the gas-separating chamber, and the lower end-in the back part of the liquid chamber, and a loop is made in the lower part of the gas- lift pipe. EFFECT: enhanced efficiency of processing. 2 cl, 3 dwg
