Lateral feeding-type hydrocyclone

Abstract

The invention discloses a side-feed type cyclone which can precisely adjust and control the flow velocity of the liquid-phase swirl on the outside. The sealing cavity formed between the jacket and the swirl tube; the upper section of the swirl tube is provided with an internal thread to match the external thread of the flow rate regulating valve and seal the top end, and the middle section is tangential to the inside of the outer jacket and the wall of the swirl tube. On its inner circle, a number of rectangular slits are evenly arranged, and the lower section extends to the outside of the outer jacket; the flow rate regulating valve and part of the swirl tube are arranged outside the outer jacket, and the front section of the flow velocity regulating valve is a cylinder, and the rear section is provided with external threads, respectively. The inner circle of the swirl tube is matched with the inner thread; the size of the tangential slit of the swirl is adjusted through the rotary flow rate regulating valve to realize the adjustment and control of the liquid phase swirl flow rate and the residence time in the swirl tube, which is suitable for solid / liquid cyclone separators Solid and liquid separation of different properties in applications and physical and chemical reactions of different properties in tubular reactor applications.

Description

technical field [0001] The invention relates to a cyclone, in particular to a side feed type cyclone. Background technique [0002] A fluid or hydrocyclone is a device that uses the pressure of a fluid or water phase to generate a swirl effect, and it is widely used in the separation of heterogeneous substances in fluids. The basic principle is: under a certain pressure, the fluid enters the cyclone at a tangential direction to the inner circular cavity of the cylindrical shell, generating a high-speed swirling field. Under the action of the swirl field, material particles of different densities in the fluid (such as solid particles in the water phase, liquid phase particles or small oil droplets, bubbles, etc.) will move in different directions relative to the continuous phase such as the water phase or the organic phase. For example, the denser particles will move outward along the meridian, and when they reach the slow flow layer or stagnant layer of the cylindrical wall...

Therefore, in some systems, the kinetics of this reaction process are slow or cannot be optimized

In order to increase the reaction speed and optimize the reaction process, it is necessary to strengthen or optimize the mixing degree of the liquid phase (homogeneous or heterogeneous). The traditional method is to install mechanical stirring or install fins or baffles on the tube wall of the tubular reactor However, the former increases equipment investment and operating costs, and the mixing intensity of the latter cannot be adjusted at any time or is difficult to predict.
