A DUST COLLECTOR AND METHOD FOR CONTROLLING EXHAUSTION OF A BAG FILTER OF A DUST COLLECTOR

摘要

Disclosed is a technique related to a filter dust collector. According to one or more exemplary embodiments, a dust collector includes a dust collector, a hood, a fan, a stack, first and second pressure sensors, an oxygen sensor, and a control device to maintain an oxygen concentration below a minimum oxygen concentration. Control whether or not the jet of air jet is injected. The dust collector includes a bag filter, an air jet injector for injecting an inert gas to degas the bag filter, and a dust rejection for collecting dust separated by the bag filter. Installed near the dust source and connected to the dust collector inlet through the duct, the fan is connected to the dust collector outlet through the duct and driven by the fan motor to discharge the filtered gas through the connected stack, Is whether or not the jet of the air jet is injected according to the oxygen concentration measured by the oxygen pressure measured by the dust collector differential pressure and the oxygen sensor which is the difference between the measured values of the first pressure sensor measuring the pressure on the dust collector inlet side and the second pressure sensor measuring the pressure on the dust collector outlet side Determine.
