Two major improvements to effectively improve the working efficiency of the cyclone water separator

Cyclone water separator is a kind of equipment used for the separation of gas-solid system or liquid-solid system. Its working principle is to rely on the rotational movement caused by the tangential introduction of airflow, so that solid particles or droplets with large inertial centrifugal force are thrown to the outer wall. separate. The main features of this separator are simple structure, flexible operation, high efficiency, convenient management and maintenance, and low price. It is used to capture dust with a diameter of 5-10μm or more. It is widely used in the pharmaceutical industry and is especially suitable for coarse dust particles. , With high dust concentration, under high temperature and high pressure conditions, it is also often used as an internal separation device in a fluidized bed reactor or as a pre-separator. It is a widely used separation equipment in industry.
　　By improving the local structure of the cyclone water separator, the working efficiency of the equipment can be effectively improved:
　　1. Change the inlet structure: In view of the asymmetry of the airflow axis in the cyclone dust collector, the inlet is changed from a single inlet to a double inlet. The experimental study of the flow field in the double inlet cyclone dust collector shows that the axis of the flow field of the double inlet cyclone dust collector The symmetry is better than the single-import cyclone dust collector, and the vortex core deformation of the double-import cyclone dust collector is small; the internal tangential speed of the double-import cyclone dust collector is about 6% higher than that of the single inlet, and the attenuation is slow in the quasi-free vortex zone; the double-import cyclone dust collection The short-circuit flow of the exhaust core pipe of the device is less than that of a single inlet. The double-import cyclone dust collector is more conducive to improving the dust removal efficiency and reducing the equipment resistance than the single-import cyclone dust collector.
　　2. Change in cone structure: The diameter of the lower part of the cone has a significant impact on the efficiency of the cyclone sampler, but it does not significantly affect the degree of change in the efficiency of particles of different sizes. When the diameter of the lower part of the cone is larger than the diameter of the exhaust core tube, the reduction of the cone parameters will increase the sampling efficiency without a significant increase in resistance; however, the cone can also be seen from the resistance test results. The diameter of the weapon part should not be smaller than the diameter of the exhaust core pipe. Theoretically speaking, the decrease in the diameter of the lower part of the cone can cause an increase in the tangential speed, thereby increasing the centrifugal force; for a cyclone with the same cylinder diameter, if the cone opening is small, the maximum tangential speed is close to the cone wall. This allows the particles to be separated better. At the same time, if the cone opening is small, the vortex will touch the cone wall, making it possible for the particles to re-enter the outgoing airflow, but the latter has less impact on the cyclone sampler than the former. In short, appropriately reducing the diameter of the lower part of the cone is beneficial to the improvement of efficiency.
