Pulse control system with bag breaking positioning function

Abstract

The invention discloses a pulse control system with a bag breaking positioning function, and belongs to the technical field of filter bag dust collectors. Comprising a pulse controller, a factory or workshop level control system, and a differential pressure transmitter, a plurality of pulse valves E arranged on an air bag of the dust remover and a dust concentration sensor arranged at an air outlet of the dust remover which are respectively connected with the pulse controller, the pulse control instrument is connected with the differential pressure transmitter and the dust concentration sensor through an analog quantity input interface to detect the dust concentration value, parameter modification is performed through a touch screen on the pulse control instrument, or online modification and control monitoring of operation parameters of the dust remover are performed through an RS-485 communication interface connected with a factory or workshop level control system; and the pulse controller outputs the running state of the pulse valve and a dust alarm to the touch screen. According to the system, the broken bag detection function of the pulse controller can be realized without programming, and meanwhile, the broken position of the filter bag in the filter bag dust collector can be intuitively judged.

Description

technical field [0001] The invention relates to a filter bag leak detection and positioning system of a filter bag filter, in particular to a pulse control system with a bag-breaking positioning function, belonging to the technical field of filter bag filter. Background technique [0002] In the petrochemical field, the gas filtered by the bag filter is usually ethylene, propylene and other flammable, explosive and highly toxic dust particles, and these dusts are also chemical products with high value. After the filter bag of the dust collector is damaged, these chemical raw material particles will be discharged into the atmosphere, which not only easily causes safety accidents, but also causes economic losses. [0003] In the prior art, a dust removal control system or a dust detection system is used to solve the problem of how to detect whether there is leakage of dust and how to determine the location of the leakage. The current dust control system and dust detection sys...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the problems of using PLC control in the existing dust removal control system or dust detection system that require a large amount of programming, and the use of pulse controllers that cannot monitor dust leakage and leakage locations, and provide a pulse control system with a broken bag positioning function , Dust leakage monitoring can be realized without programming, and at the same time, the damaged position of the filter bag in the filter bag filter can be judged intuitively, which is convenient for maintenance personnel to quickly replace after entering the dust collector
