Cyclone separator with double inlet and double outlet

Abstract

The invention discloses a cyclone separator provided with double inlets and double outlets. The cyclone separator comprises a cyclone barrel body, wherein a cone, a middle ash bucket and a sewage outlet are arranged at the lower end of the cyclone barrel body in sequence; an air inlet component and an air exhausting component are arranged at the upper end of the cyclone barrel body; the air inlet component comprises a left air inlet and a right air inlet, and the left air inlet and the right air inlet are formed in the cyclone barrel body respectively; arc-shaped guiding plates are arranged in the communicating positions that the left air inlet and the right air inlet are communicated with the cyclone barrel body respectively; a gap is reserved between the top of the arc-shaped guiding plates and the cyclone barrel body; the air exhausting component comprises an air exhausting outer pipe, a connecting piece and an air exhausting inner pipe; a plurality of slotted holes uniformly distributed are formed in the side wall of the inner cone-shaped pipe of the air exhausting inner pipe. According to the invention, two main secondary eddy currents of upper eddy current and longitudinal swirling flow existing in cyclone can be effectively eliminated; the cyclone separator has the advantages that the cyclone separator is high in cyclone efficiency, low in cyclone resistance, high in operating flexibility, simple in structure, well-adapted and relatively low in cost, and has a wear-resistant lining.

Description

technical field [0001] The invention belongs to the field of heterogeneous phase separation in chemical engineering, and specifically relates to a device for continuous separation of gas-solid (liquid) mixtures, especially requiring a single unit with large processing capacity, low resistance and high separation efficiency. Cyclone separator with double inlet and double outlet. Background technique [0002] The cyclone separator is a dry gas-solid separation equipment that uses the gas non-uniform system to separate the dust from the air flow by the centrifugal force generated during high-speed rotation. Since the centrifugal force suffered by the particles is far greater than the gravity and inertial force, the minimum particle size that can be economically separated by the cyclone separator can reach 5-10 μm. In addition, the cyclone separator has a relatively simple structure, convenient operation and maintenance, stable performance, and is not limited by the concentrati...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many types of cyclone separator structures, and most cyclones are not clear in the structure of eliminating the main secondary vortex, so the separation effect on fine particles is not good.

For example, the technical solution of Chinese Patent Publication No. CN2577970Y discloses a cyclone separator, but the internal parts of the cyclone separator are relatively complicated, and have a certain effect on the separation of larger particles, but the structure for eliminating the main secondary eddy current is not clear, so Ineffective for finer particle separation

In addition, for example, the technical solution of Chinese Patent Publication No. CN101422757A discloses a cyclone separator. The cyclone separator adopts the structure of the taper opening at the lower part of the exhaust pipe, which significantly reduces the influence of the upper vortex and affects the fine air. The separation efficiency of particles has been greatly improved, but the influence of longitudinal vortex flow still exists
