low-pressure pulse jet bag filter

IntroductionThe filter in October 1981 by the Ministry of Metallurgical Industry Safety and Technical Supervision Bureau of argument and through the scientific research, confirmed YMD-I-type low-pressure injection pulse dust filter technology and its application in the structure and the reasonableness of the main performance, advancedWoke PrincipleDusty gas from the inlet into the cabinet, to be purified through the bag, the net gas Kong Jingwen's tube into the tank, discharged from the exhaust port, increasing the dust bag outer surface, the filter resistance increases, for the equipment resistance to maintain within a certain range, the surface of the bag to remove dust, cleaning the time the order is triggered periodically by the controller of the control valve, open the embedded pulse valve, the compressed air from the air bag on the nozzle injection pipe (the primary air ), induced by the venturi wind around several times in the first air (secondary air) into the bag, in an instant reverse flow wave and vibration, shaking of dust, fall into the lower casing, the exhaust valve discharge body. In the cleaning process, each time said injection pulse width, typically only 0.1-0.2 seconds, all the bag to complete a cleaning cycle for the pulse period of time.Technical performance No.ModelRowsNumber of bags(Article) Filter area(m2)Air volume(m3/h)Collection efficiency(%) Inlet dust concentration(mg/m3)Equipment resistance(Pa)Weight(T)1YMD-IType 28 Bags 42820.53075-430599-99.52000-1600080-10010182YMD-IType28 Bags B42820.53075-43053YMD-ITyp42 Bags 64230.54620-647012654YMD-ITyp56 Bags 85641.16165-863015805YMD-ITyp70 Bags107051.47710-1080016726YMD-ITyp84 Bags128461.79255-1295719457YMD-ITyp112 Bags 1611282.212330-1726229808YMD-ITyp140 Bags 20140102.815420-2160030309YMD-ITyp168 Bags24168120.318045-252633520
