Efficient cyclone separator adopting liquid washing

The invention provides an efficient cyclone separator adopting liquid washing. An upper annular plate and a lower annular plate of an interface fluid director of the cyclone separator are both horizontally arranged, an annular fluid director is vertically arranged, the upper annular plate, the annular fluid director and the lower annular plate are all coaxially arranged with a cylinder, the upper annular plate is located in an upper end socket and connected with the lower end of an air outlet pipe, the lower annular plate is located in the lower portion of the cylinder and located in the washing liquid, vertical flow deflectors of the annular fluid director are located between the upper annular plate and the lower annular plate and connected with the upper annular plate and the lower annular plate respectively, the lower ends of the vertical flow deflectors are located in the washing liquid, and the vertical flow deflectors are arranged in the gas rotating direction from inside to outside. Two or more vertical flow deflectors are uniformly distributed along the circumferential direction of the annular fluid director. The cyclone separator can obtain as high cyclone trapping efficiency as possible by using as little liquid as possible, improves the separation efficiency of solid particles of 5 microns or smaller, and is ingenious in design, simple in structure, simple and convenient to manufacture, low in manufacturing cost and suitable for large-scale popularization and application.
