Shunting guide type inertia cyclone separator

Abstract

The invention relates to a shunting guide type inertia cyclone separator which comprises a coalescence shunting type inlet and a barrel body; the coalescence shunting type inlet comprises a tangential inlet, a coalescence pipe, a flow guide body, a conversion pipe and a shunting guide pipe; and the barrel body is formed by sequentially connecting a rotational flow section, a conical section and an underflow section which have the same central axis from top to bottom, an inner cone is connected to the axis of the top of the barrel body, and an overflow pipe is arranged at the center of the underflow section. A continuous phase, a large-particle-size dispersed phase and a small-particle-size dispersed phase can be shunted and layered under the action of inertia through the shunting guide type inlet, three different fluids are guided to different positions in the cyclone through an inner-layer guide plate and an outer-layer guide plate, and the dispersed phases with different particle sizes are finely separated. The cyclone can realize higher separation efficiency on dispersed phases with large and small particle sizes, and has the outstanding advantages of small equipment volume, realization of targeted shunting and guiding effects on liquid drops with different sizes so as to finish efficient separation and the like.

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.

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
