Description

technical field [0001] The invention relates to the technical field of particle separation, in particular to an ultrafine particle separation system under a coupling mechanism. Background technique [0002] At present, many industrial processes will produce a large number of fly ash particles, such as the power generation process of coal-fired power plants, catalytic cracking process and so on. These fly ash particles can be collected by various forms of conventional dust removal equipment, such as electrostatic precipitators, baghouses, cyclones and wet dust collectors. Among them, the cyclone separator has become the preferred equipment for this process due to its advantages of simple design, cheap manufacture, low maintenance cost, and wide adaptability to operating conditions. However, these conventional dust removal equipment are not effective in collecting ultrafine particles. For example, the mass dust removal efficiency of high-efficiency electrostatic precipitators...

Problems solved by technology

However, when the existing turbulence coalescing device is applied to the cyclone separator to achieve ultrafine particle separation, in order to achieve higher separation efficiency, it is often necessary to enhance the coalescence effect with electric field force to achieve a higher separation effect, which often brings The additional increase of other costs, such as the increase of the electric field, greatly increases the power consumption, and requires a complex power control system, which increases the cost and the frequency of maintenance. Pursue the turbulent flow of a single mechanical structure and apply it to the cyclone separator to achieve the purpose of efficiently separating ultrafine particles
