Problems solved by technology

However, different from this industry, in the cement industry, especially in the dust collection system at the kiln tail, due to the start and stop of the raw material mill and part of the hot air being sent to the coal mill system, the air volume handled by a single device often occurs. This will directly lead to a great change in the time when the broken bag dust reaches the dust monitoring device. If a broken bag occurs under different circumstances, the leaky bag positioning device will make a wrong judgment, not only the location of the broken bag cannot be found , will also increase the labor intensity of workers

Abstract

The invention discloses a bag leakage detecting and positioning device and a bag leakage detecting and positioning method for a pulse bag dust collector. The bag leakage detecting and positioning device is characterized in that the pulse bag dust collector comprises at least two air chambers, wherein an air inlet and an air outlet are formed in each air chamber; multiple columns of filter bags are arranged in each air chamber; each column of filter bags is connected with a spray pipe; an electromagnetic pulse valve is arranged on each spray pipe; signal input terminals of all electromagnetic pulse valves are connected with an input / output (I / O) port of a controller; air outlets of all the air chambers are connected with an air outlet header pipe; a dust concentration sensor is arranged on the air outlet header pipe; an output terminal of the dust concentration sensor is connected with the controller through a digital / analog converter; the I / O port of the controller is connected with an alarm. According to the device, the bag leakage can be rapidly and accurately detected and positioned, and the device has the advantage of simple structure.

Description

technical field [0001] The invention relates to the technical field of pulse bag dust collectors, in particular to a leaky bag detection and positioning device for pulse bag dust collectors and a detection and positioning method thereof. Background technique [0002] The pulse jet bag filter has the characteristics of high dust removal efficiency, low equipment cost, small footprint, and can provide online and offline dust cleaning. Its working principle is: during normal operation, the dust-laden gas enters each ash hopper through the air inlet, part of the dust falls into the ash hopper, and most of the rest of the dust rises into the bag room above the ash hopper with the airflow, and after being filtered by the filter bag, the dust remains in the dust hopper. On the outside of the filter bag, the purified gas enters the clean gas chamber from the inside of the filter bag, and then is discharged into the atmosphere through the air outlet, so as to achieve the purpose of p...
