Cyclone separator with damping reduction device

Abstract

The invention relates to a cyclone separator with a damping reduction device. The damping reduction device is positioned in a core tube at the top of the cyclone separator, the damping reduction device is provided with a section of circular-tube blade root which is coaxially arranged with the core tube, a plurality of blades are peripherally arranged on the blade root, the blades are continuous and smooth curves, an alignment line of the blades on a folding face of the outer wall of the circular-tube blade root is formed by a straight line section at the upper portion and a smooth curve at the lower portion, and the straight line section is parallel to the axis of the circular-tube blade root. The damping reduction device is integrally formed by the circular-tube blade root and the blades. The cyclone separator with the damping reduction device can enable rotation motion of air flow in the core tube to be partially converted into straight-line motion, can enable rotation energy of part of the air flow to be converted into static pressure energy, can effectively reduce overall pressure drop and achieves the purpose of damping reduction and synergy. The damping reduction device is low in manufacture cost, simple in structure and free of motion parts. The cyclone separator can stably work for a long time under complex work conditions.

Description

technical field [0001] The invention relates to a cut-flow rotary cyclone separator, in particular to a cyclone separator with a drag reducing device for separating solid particles from a gas-solid mixed flow. Background technique [0002] Cyclone separator is a common gas-solid separation equipment, such as Figure 5A , Figure 5B As shown, the existing cut-flow rotary cyclone separator 9 is generally composed of a core pipe 91, a cylinder body 92, a cone 93, an ash hopper 94, and a material leg 95; , the airflow will change from linear motion to circular motion. Most of the swirling air flow spirals downward from the cylinder along the wall of the device, and flows toward the cone 93, which is usually called an external swirling air flow. The dust-laden airflow generates centrifugal force during the rotation process, and throws the dust particles with a density greater than the gas density to the wall; once the dust particles contact the wall, they lose their inertial fo...

Problems solved by technology

However, under the conditions of high temperature and high concentration or when collecting particles below 5 μm, multi-stage series operation is often used, and the energy consumption is obviously too high, and the pressure drop increases sharply with the increase of the size of the cyclone separator.
