Pulse dust removal controller of bag-type dust remover

Abstract

The invention discloses a pulse dust removal controller for a bag type dust collector. The device comprises a control module, three precision adjustable encoders, a 10-path pulse switch and two pathsof switching values, the control module comprises a control chip STC15W408AS and a peripheral circuit thereof. The 10-path pulse switch is connected with the control module; the number of paths of pulse switches and the interval time of two adjacent paths of pulse output can be controlled by adjusting the precise adjustable encoder; the control system controls on-off of pulses according to signalsof the control chip STC15W408AS, when the 10-path pulse switch cannot work normally, expansion can be conducted through two paths of switch cascade connection; by means of the invention, pulse ash removal of cloth bags of various types of cloth bag type dust removers is achieved based on a low-cost and high-performance digital controller.

Description

technical field [0001] The invention relates to various industrial dust removal equipment fields such as coal power plants, steel mills, and shot blasting machine workshops, and in particular to a pulse dust removal controller for bag type dust collectors. Background technique [0002] Since the reform and opening up, my country's industrial field has developed rapidly. At present, China has become the largest country with the most comprehensive industrial technology reserves. In the context of industrial development, pollution problems have also followed, including coal power plants, shot blasting machine workshops and other enterprises. A large amount of dust will be emitted during the production process. The National Health Commission released the 2018 National Occupational Disease Report: In 2018, a total of 23,497 new cases of various occupational diseases were reported nationwide, and 19,524 cases of occupational pneumoconiosis and other respiratory diseases, including o...

Problems solved by technology

[0003] In recent years, due to the technical breakthrough of the bag filter, its great advantages in terms of cost and dust removal effect have made foremen and workshops in many fields choose to use the bag filter for dust treatment of industrial waste gas. The bag filter The market share of the bag filter has shown an increasing trend in the past 10 years. The bag filter will cause dust to accumulate and solidify during dust removal, which will reduce the dust removal efficiency and service life of the dust bag. Dust removal quality of dust bag
