VORTEXGAS-LIQUIDSEPARATOR

Abstract

Results of a research of the vortex contact device of the tangential type intended for separation of drops and cleaning of industrial emissions of gaseous inclusions in rectifying and absorbing columns, hydrolysis devices, dryers, evaporators, scrubbers, gas-liquid reactors are presented. In which removal of disperse particles from a stream and absorption of components of gas is carried out directly in the rotating gas-liquid layer of absorbent in the field of the greatest influence of forces of inertia and a high-speed pressure of gas. What allows to reach the high speed of the movement of a gas stream and to provide catching of drops up to 0.4 kg on one kilogram of air. In work, two types of zavikhritel are investigated and the main modes of interaction of gas with liquid bubbling and ring are revealed. The size of coefficient of hydraulic resistance of the contact device was equal 0.8–1.1, and a share of a bryzgounos – less than 0.01. It is established that at an expense of drops in a gas stream up to 0.01 kg/s, the size of coefficient of resistance has increased by 1.25 times. Values of superficial coefficient of a massootdacha at gas absorption by liquid are reached equal to 0.9·10-3 m/c., and the interphase surface has made equal 0.1–0.9·10-3 m/c.Advantage of the specified device is his steady and effective work in the wide range of loadings on gas, liquid, rather low hydraulic resistance, and small metal consumption. Dependences for determination of gas content, angular and linear speed, height of the rotating layer of liquid and size of coefficients of a massootdacha allowing to carry out calculation of industrial samples of the corresponding equipment are presented.
