How is a bag filter dust collector daily maintained

In order to ensure that the bag filter is operating properly, and as far as possible before the filter pulse dust collector and material are damaged, find out the existing problems and carry out routine inspections of the dust removal system. The inspection includes: whether the air regulator pressure is set properly and the pressure of the supplied air bag is correct. Check the valve operation visually during the cleaning cycle. Check the pulse duration and the pause time between two pulses. Review DCS monitoring and recording bag filter operating parameters such as intake and exhaust temperature, total pressure drop, and pressure drop across each chamber. Record all abnormal conditions and properties of the boiler and check the operation of the corresponding dust collector. Check the electric ash discharging valve to check the ash discharge and ash handling system operation of the ash hopper.

In addition to the daily inspections mentioned above, all pressure sensors must be recalibrated once a year and overhauled with pulsed dedusting air compressors. All valves, stencils, access doors, filter bags, and pulse cleaning of the bag filter must also be checked at scheduled downtime. Ash control device and piping. In addition, one or two filter bags are randomly removed from each chamber each year for laboratory analysis to help predict the life of the filter bags and consider whether it is necessary to replace the filter bags in advance.
