Cyclone separator

Abstract

The invention discloses a cyclone separator with an air speed control device. The cyclone separator consists of an intake pipe, a first airflow monitoring meter, an adjusting valve, a fastening piece,an exhaust pipe, a second airflow monitoring meter, a cone, an exhaust pipe and a baffle plate; the first airflow monitoring meter is mounted on the intake pipe; the adjusting valve is arranged underthe first airflow detecting meter, and is connected to the left upper side of the cone through the fastening piece; the exhaust pipe, inserted in a cylinder by a certain depth, is mounted at the topof the cone; the second airflow monitoring meter is mounted on the exhaust pipe; the adjusting valve is arranged under the second airflow detecting meter; a dust discharge pipe for receiving fine powder is mounted at the bottom of the cone; and the baffle plate is mounted inside for combination to form the cyclone separator with the air speed control device. Through monitoring and control of the air speed, the separation efficiency of the cyclone separator is greatly improved, both convenience and speediness are achieved, and the use cost of users is reduced.

Description

technical field [0001] The invention specifically relates to a gas velocity control device for a cyclone separator. Background technique [0002] Cyclone separator is a kind of equipment used for the separation of gas-solid system or liquid-solid system. It is widely used in mining, cement and pharmaceutical industries. It is especially suitable for coarse dust particles, high dust concentration, high temperature and high pressure conditions. It is also often used as an internal separation device of a fluidized bed reactor, or as a pre-separator. [0003] The movement of gas and solid particles in the cyclone separator is very complicated, and there are tangential, radial and axial velocities at any point in the cyclone separator, which vary with the radius of rotation. The current cyclone separator has certain defects in the adjustment and control of the gas velocity: if the gas velocity is too small, the separation efficiency is not high. However, if the gas velocity is ...

Problems solved by technology

The current cyclone separator has certain defects in the adjustment and control of the gas velocity: if the gas velocity is too small, the separation efficiency is not high

However, if the gas velocity is too high, it is easy to generate eddy current and serious back-mixing phenomenon, which will also reduce the separation efficiency, and the quality and purity of the separated product will be greatly reduced.
