Centrifugal deduster and dedusting system

Abstract

The invention discloses a centrifugal deduster and a dedusting system, and relates to the technical field of dedusting devices. The centrifugal deduster includes an outer shell, the top end of the outer shell is provided with an air inlet channel, the bottom end of the outer shell is provided with a first dust channel, a spherical shell is arranged in the outer shell, the spherical shell is communicated with the air inlet channel, the spherical shell is provided with a second dust channel, the second dust channel is nested in the first dust channel, a first chamber is arranged in the sphericalshell, the first chamber is respectively provided with an exhaust channel and a third dust channel, the exhaust channel is nested in the air inlet channel, the third dust channel is nested in the second dust channel, a plurality of second chambers are arranged in the spherical shell, every second chamber is provided with a first channel and a second channels respectively, the first channels are communicated with the first chamber, the second channels are communicated with the outer shell, every second chamber is further provided with a third channel, and the third channels are communicated with the spherical shell. The dust back-mixing probability can be reduced, so that the separation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a centrifugal dust collector and a dust removal system. Background technique [0002] When the dust-laden gas rotates, the dust particles in the airflow will be separated from the airflow due to the centrifugal force. This dust removal technology is called centrifugal dust removal technology. The equipment that uses centrifugal dust removal technology for dust removal is called centrifugal dust collector. Centrifugal dust collector is one of the most widely used dust removal equipment in the industry. It is mostly used as equipment for smoke and dust removal, multi-stage dust removal and pre-dust removal for small coal-fired boilers. It is used to separate and remove harmful dust in the flue gas, reduce or eliminate the pollution of the exhaust gas to the environment and the atmosphere, or capture and recycle useful dust in the airflow to reduce material loss. ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when the centrifugal dust collector is started, an internal swirling flow and an external swirling flow are formed inside the centrifugal dust collector. Due to the mutual interference and penetration of the inner and outer swirling airflows, it is easy to bring up the dust settled at the bottom. , so that some of the fine dust particles are taken away by the airflow, which affects the dust removal efficiency of the centrifugal dust collector
