Coupling type inertial cyclone fluid particle heterogeneous separation device and method

Abstract

The invention relates to a coupling type inertial cyclone fluid particle heterogeneous separation device and method. The device comprises an inertial curve and a cyclone separator coupled with the inertial curve and provided with an integrated volute tangential inlet. The inertial curve and the cyclone separator are integrally coupled, the fluid phase and the particle phase firstly enter an inertial curve body through an external pipeline, the differential particle concentration gradient is generated, the fluid phase and the particle phase enter the cyclone separator integrally coupled with the inertial curve to be separated, and therefore the defects existing in the separation process under the particle concentration uniformity or concentration-gradient-free condition in the traditional separation process are overcome. The inertial curve is organically integrated into fluid-particle radial concentration space, the concentration gradient with the outer portion higher than the inner portion is generated under the effect of a centrifugal field, the particle penetration amount caused by short-circuit current entrainment after particles enter the cyclone separator can be reduced, the distance or time of the particles moving towards the capture wall is shortened, and the heterogeneous separation efficiency is effectively improved under the condition that the pressure drop of the separator is not obviously increased.

Description

technical field [0001] The invention relates to a fluid particle heterogeneous two-phase (gas-solid or gas-liquid) separation and purification technology, in particular to a coupled inertial swirling fluid particle heterogeneous phase separation method and its device. Background technique [0002] Cyclone heterogeneous separation equipment (that is, cyclone separator, including cyclone separator and hydrocyclone, etc.) has the advantages of simple structure, low cost and easy maintenance, and is suitable for harsh operating environments such as high temperature, high pressure, and high corrosion , Widely used in the separation and purification of gas particles in the fields of energy, chemical industry, materials and environment. When the non-uniform two-phase flow (dilute phase or dense phase) of fluid particles enters the inner space of the cyclone separator, the spiral movement flows downward into the lower part of the separator, and reverses upward after reaching the nat...
