Cyclone separators and experimental systems with diverging inlets, deflectors and dust screens

Abstract

The invention discloses a cyclone separator with a gradually enlarged inlet, a flow guide plate and a dustproof screen and an experiment system, and belongs to the technical field of gas-solid heterogeneous separation. The inlet of the cyclone separator is the gradually enlarged inlet which is internally provided with two flow guide plates, including a primary flow guide plate and a secondary flow guide plate; the dustproof screen is installed on the bottom of a central gas discharge pipe. The structure of the experiment system of the cyclone separator is that an air compressor is connected with the gradually enlarged inlet of the cyclone separator via a gas conveying pipeline; the gas conveying pipeline is sequentially provided with a temperature sensor, a mass flow rate meter, a first pressure sensor, an inlet of a solid particle feeder and a second pressure sensor; the central gas discharge pipe of the cyclone separator is connected with a dedusting device. According to the invention, a single dust-containing gas source is distributed by multiple channels; the flow state of the dust-containing gas streams is optimized; under the equal total gas intake amount, the treatment amount of the separator is improved; the flowing path of the dust-containing particles is changed by the dustproof screen; fine particles are effectively prevented from overflowing from the central gas discharge pipe; the separation efficiency is improved; the system pressure loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of gas-solid heterogeneous phase separation, and in particular relates to a cyclone separator and an experimental system with a gradually expanding inlet, a deflector and a dust-proof net. Background technique [0002] The gas-solid cyclone separator is a device that separates the solid particles in the dust-laden gas from the gas it carries. The gas enters the separation cylinder of the cyclone from the tangential or axial inlet, and the centrifugal force generated by the rotating air flow separates the gas-solid mixture. The cyclone separator is generally composed of air inlet, separation cylinder, central exhaust pipe, ash hopper and other parts. The cyclone separator has the advantages of simple structure, easy to use, stable operation, low cost, high efficiency, and convenient maintenance. It is widely used in environmental protection, cement, pharmaceutical, power generation, chemical industry and oth...

AI Technical Summary

Problems solved by technology

When the diameter of the solid particles in the dust-laden airflow is small and the density is light, a small part of the particles do not follow the mainstream gas and move spirally along the separation cylinder, but directly overflow from the central exhaust pipe of the cyclone, which will seriously affect the performance of the separator. Efficiency, not conducive to energy saving and emission reduction
