A split-guided inertial cyclone separator

Abstract

A split-guided inertial cyclone separator, comprising a coalescing split-flow inlet and a barrel; the coalescing split-flow inlet includes a tangential inlet, a coalescing pipe, a guide body, a conversion pipe, and a split-flow guiding pipe; the barrel The body is composed of a swirl section, a cone section, and an underflow section with the same central axis from top to bottom. The present invention can separate and stratify the continuous phase, the discrete phase with a large particle size and the discrete phase with a small particle size under the action of inertia through the split-guided inlet, and guide three different fluids to the cyclone through the inner layer and the outer layer guide plate At different positions inside, the discrete phases with different particle sizes are finely separated. The cyclone can achieve high separation efficiency for dispersed phases with large and small particle sizes, and it has outstanding advantages such as small equipment volume and targeted diversion and guidance for droplets of different sizes to complete efficient separation.

Description

technical field [0001] The invention relates to a diversion-guided inertial cyclone separator, which is mainly used in the fields of petroleum, chemical industry, environmental protection and the like, and is specifically a two-phase separation treatment technology. Background technique [0002] At present, the separation methods for two-phase immiscible media mainly include gravity sedimentation method, electric field separation method, chemical adsorption separation method and filtration separation method. Cyclone separation technology is widely used in petroleum, chemical industry and other fields due to its fast separation speed and small equipment. Environmental protection and other fields. For the cyclone separation technology, the cyclone separation method is difficult to separate the dispersed phase with small size. The particle size distribution of the dispersed phase is one of the important factors that determine the efficiency of the cyclone separation. In practic...

Problems solved by technology

For the cyclone separation technology, the cyclone separation method is difficult to separate the dispersed phase with small size. The particle size distribution of the dispersed phase is one of the important factors that determine the efficiency of the cyclone separation. In practical applications, large The separation effect of particle size droplets is good, and the separation effect of small particle size droplets is poor. These droplets with small particle size directly follow the continuous phase and flow out from the continuous phase outlet without separation, which has a certain impact on the separation effect.

[0003] The cyclone separation system or device has been applied in related industries in my country. The invention patents for the cyclone separation system or device, such as (CN201310063840.8, CN201610184831.8, CN201610157839.5, CN201610126588.4, CN201620006971.1, CN201520974246.9), etc., but the above inventions all have the disadvantage of poor separation effect on small particle size dispersed phases when separating the liquid flow, which limits the improvement of the separation efficiency of the cyclone
