Automatic cleaning technique of dust collection tube of dust removing system

Abstract

The invention relates to an automatic clean technology for a dust pipe of a dust removal system. The technology makes use of the characteristics of a balance flap valve that under a certain pressure, the balance flap valve can automatically open and close and regulate network air volume to cause a dust removal system fan to periodically and rapidly operate in an operation state of low load for a long time; the changes of network pressures are used for controlling and balancing the opening and closing of the balance flap valve to cause a dust pipe network to periodically operate at a designed rated flow rate; and the accumulated dust in the pipe enters a dust removal device to be purified along with airflow and the purified air is finally discharged into the atmosphere. Compared with the dust removal system which has a plurality of dust removal points, strong randomness of dust removal point work, high concentration of dust in the airflow and dust removal pipes which can only be arranged horizontally, the automatic clean technology can timely and effectively eliminate the pipe dust which is caused by a long period of a technology operation at low speed of the dust removal system along and simultaneously the balance flap valve of the automatic clean technology for the dust pipe of the dust removal system can also eliminate the surge phenomenon of the dust removal system fan.

Description

technical field [0001] The invention relates to an automatic cleaning process for the dust accumulation pipeline of the dust removal system, which is mainly used for cleaning the dust accumulation pipeline of the dust removal system with a large number of dust removal points, strong randomness in the work of the dust removal points, high dust concentration in the air flow, and the dust removal pipeline can only be arranged horizontally . Background technique [0002] The operating conditions of each dust removal point of the dust removal system are closely connected with the operating conditions of the process equipment. For a dust removal system with a large number of dust removal points, strong randomness in the work of dust removal points, high dust concentration in the airflow, and dust removal pipes that can only be arranged horizontally, since the number of dust removal points and dust removal positions are randomly adjusted with the operation of process equipment, the...

AI Technical Summary

Problems solved by technology

Since the cross-section of the dust removal pipeline cannot be adjusted, when the flow rate of the dust removal pipe network decreases with the adjustment of the process, the flow rate in the pipe network will drop sharply, and the phenomenon of dust accumulation in the pipe network will be very serious. operation, and it is easy to cause the paralysis of the operation of the dust removal pipe network
