Filtration wind speed: also called air-bub ratio, refers to the filtration speed of the flue gas through the filter bag, or the relationship between the amount of flue gas per unit area of the filter bag, and the unit is m/min.
Sub-chamber: A unit consisting of a number of filter bags arranged regularly inside the dust collector is called a chamber. A single bag filter is composed of a number of chambers. The upper chambers of the structure are separated by partitions. Each chamber is a dust collector. A sub-room.
Total filter area: The total filter area of a single filter bag is the total filter area, and the unit is m2.
Single room filter area: refers to the sum of the area of filter bags in each sub-room, the unit is m2; the accumulation of sub-room filter area is equal to the total filter area.
Low-pressure rotary pulse jet: refers to the type of filter bag cleaning method, the lower pressure of the cleaning gas stream with the same time through the rotary jet arm spray hole with a certain pressure of the instantaneous pulse to clear the filter bag.
Pulse pressure: refers to the compressed air pressure set by the air bag connected with the pulse valve before the pulse valve works. The unit is KPa.
Pulse Width: The duration of the pulsed electrical signal that instructs the solenoid valve of the pulse valve, in units of s or ms.
Pulse interval: refers to the interval between pulse valves that work in sequence, and the unit is s.
Online cleaning: refers to the way the filter bag is cleaned while filtering the smoke.
Off-line cleaning: refers to the method of cleaning dust when the filter bag stops filtering the flue gas. Off-line cleaning generally requires the dust collector to have a compartment structure and a mechanism for cutting off the flue gas of the compartment.
Filter bag pressure difference: refers to the resistance of the filter bag and powder layer produced during the filtration process. The unit is Pa.
