Description

Technical Field

[0001] The present invention relates to the technical field of dust collector monitoring, and specifically to an intelligent monitoring and control system for dust collectors. Background Art

[0002] With the rapid development of current social automation and intelligence, and the increasing scope and quantity of dust collector use, the demand for the intelligence and automation of dust collectors is increasing day by day. This has led to low efficiency of traditional control methods under the premise of meeting technical standards. Moreover, when the dust removal system is operating, the operator needs to observe the on-site dust concentration to start or stop the dust removal equipment. In addition, when a fault occurs during the operation of the equipment, it cannot be detected and stopped in time, resulting in the equipment often being in a sub-healthy operating state, which causes great damage to the equipment. Also, it is necessary to manually conduct detailed inspections of the filter elements regularly, which is time-consuming and laborious. There is no monitoring means for the dirty air entering the dust collector box, resulting in damage or scrapping of the filter material by the dirty air entering the dust collector.
