Abstract

The invention discloses a cyclone separator, and belongs to the field of oil refining chemical engineering apparatuses. The cyclone separator comprises a gas inlet, an outer arc board, a top board, a gas discharge tube, an outer cylinder arranged at the bottom of the outer arc board and a solid discharge device arranged at the bottom of the outer cylinder, the gas discharge tube stretches into the outer arc board, an annular space is formed between the gas discharge tube and the outer arc board, the cyclone separator also comprises an injection device used for injecting a gas or vapor, the top board is provided with a first through hole, the injection device is arranged in the first through hole, and the injection end of the injection device faces the sidewall of the outer edge of the annular space. The top board is provided with the injection device along the inner wall of the outer arc board, so the injection device can provide downward injected jet, and the jet can inhibit secondary flow in the annular space in order to eliminate a top dust ring, so the separation efficiency of the cyclone separator is improved.

Description

technical field [0001] The invention relates to the field of oil refining and chemical equipment, in particular to a cyclone separator. Background technique [0002] The cyclone separator is a device that uses centrifugal force to separate gas and solid particles. The cyclone separator is one of the important equipment of the oil refining catalytic cracking unit. [0003] The existing cyclone separator includes an outer arc plate, an air inlet is installed on the side wall of the outer arc plate, a top plate is installed on the top of the outer arc plate, an exhaust pipe is arranged on the top plate, and the exhaust pipe extends into the outer arc plate The interior forms an annular space with the outer arc plate. An outer cylinder is installed at the bottom of the outer arc plate. A cone is installed at the bottom of the outer cylinder. A dust discharge port is arranged at the bottom of the cone cylinder. After entering the cyclone separator from the air inlet for treatmen...
