High-speed vortex electric field and cyclone combined separation method and cyclone separator

Abstract

The invention relates to a high-speed vortex electric field and cyclone combined separation method and a cyclone separator. The method comprises the following steps: two electric fields independent from each other are arranged in the cyclone separator, an entrance section is used as an electrostatic field, and a separation section is used as a vortex electric field; an air flow containing impurities passes through the electrostatic field at the entrance section formed by a plate electrode and a corona electrode, and enters the vortex electric field at the separation section, impurity particles are ionized in the electrostatic field, electrified particles rotate at an accelerated speed in the vortex electric field under the combined action of the lorentz force and the electric field force, and the impurities impact the wall surface to be separated in a gathering manner through adjusting the electric field parameters. Compared with the traditional cyclone separator, the cyclone separator provided by the invention, can achieve better separating effect.

Description

technical field [0001] The invention relates to a high-speed vortex electric field cyclone separation method and a cyclone separator, in particular to a composite separation technology and device combining electric field separation and cyclone separation. Background technique [0002] In industrial production, cyclone separators are often used for gas-solid-liquid separation in places where a large amount of dust is generated or where solid particles and liquid droplets carried in the transport gas need to be removed as much as possible. The cyclone separator has the following advantages: ① no moving parts, reliable and safe operation; ② low maintenance cost, simple and convenient daily maintenance; The better the separation. [0003] figure 1 It is a structural diagram of a general cyclone separator, including the inlet section 2, the separation section 6, the exhaust pipe 9 and the impurity discharge port at the bottom of the separation section; the upper part of the sep...
