The separation of heterogeneous separation device has wide practical value in many industries. It is a mechanical separation operation according to the different characteristics of continuous phase and dispersed phase. The purpose is, on the one hand, to purify the dispersing medium to obtain a pure gas or liquid, and, on the other hand, to collect the dispersing material to obtain the finished product. In recent years, more and more attention has been paid to the effect of heterogeneous separation devices on environmental protection.

The heterogeneous separation test device is mainly composed of fan, dust adding bottle, cyclone separator, product receiving bottle, switch, indicator light, control panel, etc. The fan is a type CRZ-70 centrifugal medium pressure fan. The air volume is 4803m/h, the wind pressure is 1300Pa, and the input power is 250W. The rotational speed is 2800r/min. The cyclone separator is made of plexiglass so that students can observe the movement of objects in the separator. And what it's made of. The dust used for separation is 60~80μm silica gel particles. Because of its water absorption and discoloration characteristics. By changing color, we know that its mass will change. Press the switch indicator light, indicating that the corresponding related work is in progress, when terminating, press the arrow on the switch knob to turn off. In case of emergency, it is necessary to stop immediately and power off directly. After power off, it is necessary to turn off each switch separately. This situation should be avoided as far as possible. Heterogeneous separation apparatus where you can control some of the operation of the experiment and watch the whole process of cyclone separation.

Principle of heterogeneous separation experimental device: The dust-bearing gas enters the rectangular channel in the tangential direction from the upper part of the cyclone separator and forms an external cyclone that moves spirally downward around the center of the cylinder. After the external cyclone reaches the bottom, an upward internal cyclone is formed, and the inner and outer swirling gases rotate in the same direction. In this process, the particles are thrown to the wall and separated from the air flow under the action of inertial centrifugal force, and fall into the ash outlet at the bottom of the cone along the wall. The purified gas is discharged from the top exhaust pipe along the inner swirl.
