1.Filtration velocity : also known as gas -cloth ratio , refers to the relationship between the flue gas through the filter bag filtration rate , or to reflect the amount of flue gas treatment unit area of the bag , expressed in units of m / min. 2.Compartment : the dust bag internally by several orders of regularly arranged in units called the room , a single bag filter consists of several number of chambers , separated by diaphragms between structurally chambers, each chamber is a dust collector a compartment . 3.The total filter area : the sum of single bag filter area of the total filter area , in units of m². 4.Single-chamber filter area : refers to the sum of each sub-chamber bag area , in units of m2; cumulative compartment filter area equal to the total filter area . 5.Rotating low pressure pulse jet : refers to the type of bag cleaning mode , a low pressure gas stream with soot blowing by blowing holes of the rotating arm instantaneous pulse discharge with a certain pressure on the bag were cleaning . 6.Pulse pressure: refers to the pressure of compressed air before the air bag pulse valve pulse valve in communication with the working set , the unit is KPa. 7.Pulse width: ON pulse duration of the guiding impulse valve solenoid electrical signals in s or ms. 8.Pulse interval: mean time between pulse sequence valve between work , the unit is s. 9.Working cleaning : cleaning refers to the way the filter bag in smoke simultaneously. 10.Stop working cleaning : refers to perform cleaning of the filter bag to stop fumes manner , generally require line cleaning dust partakers cell structure and cutting compartment smoke institutions. 11.Bag pressure: refers to the flue gas resistance during the filtration process to produce the bag and the powder layer , the unit is Pa.
