LFEF glass fiber bag dust collector
LFEF glass fiber bag dust collector
LFEF glass fiber bag dust collector is a compartment back blowing bag dust collector. It usually includes the following three parts
(1) intake, exhaust and blowback systems include intake pipe, intake chamber, blowback valve, blowback pipe, tee pipe, exhaust valve, exhaust pipe and other components
bag structure includes ash hopper, inspection door, body frame, upper and lower flower plates, filter bag, bag chamber, etc
(3) the ash discharge system includes ash discharge method, screw conveyor and other components
LFEF glass fiber bag vacuum cleaner is a product specially used for dust removal of waste gas from cement kiln and dryer. The vacuum cleaner adopts microcomputer control, chamber back blowing, timing, constant resistance dust removal, temperature detection and display, etc. The equipment can change bags in different rooms without stopping. It has the advantages of simple operation and low operation cost. It can solve the problem of dust removal of waste gas from kiln and dryer
1. Strong adaptability. High temperature (260 ℃; instantaneous 280 ℃). High dust (100) g / Nm3). High temperature (dew point 60) ℃) operates under conditions
2. The dust removal efficiency is more than 89%, the discharge concentration is less than 50mg / nm, and the third is smokeless cleaning
3. Thoughtful design and reasonable structure. It can be repaired without shutdown and does not affect production
4. Long bag back blowing ash removal technology, anti condensation structure design, automatic temperature control system, long service life of filter bag
5. The equipment has simple operation and low operation cost
the basic structure of glass fiber bag filter consists of three parts
(1) air inlet, exhaust and blowback system of glass fiber bag filter: including air inlet pipe, air inlet chamber, blowback valve, blowback pipe, tee pipe, exhaust valve and exhaust pipe
(2) bag chamber structure of glass fiber bag filter: including ash hopper, access door, body frame, upper and lower flower plate, filter bag and bag chamber
(3) dust removal system of glass fiber bag filter: including dust removal valve and screw conveyor
working principle and performance parameters of LFEF glass fiber bag filter
due to the characteristics of large amount of ash wind, wide pollution range and high humidity in the waste gas of shaft kiln and dryer According to the difficulties brought by the dryer and the flue gas dust removal of the shaft kiln, the kiln is characterized by upper air inlet, the dusty flue gas enters the air inlet chamber from the upper part, and some coarse particles fall into the ash hopper inertia. During dust removal, the air flow direction is consistent with the dust settlement direction to prevent dust from flying again. In addition, due to the uniform air distribution in the inlet chamber and no sudden change in air velocity, the pressure drop balance in each bag chamber is helpful to improve the service life of the filter bag
for this type of glass fiber bag filter, its exhaust valve and blowback valve are located in the lower exhaust pipe. Dusty gas is sucked into the intake manifold under the action of exhaust fan; Enter the air inlet chamber through each air inlet branch pipe; Evenly pass through the upper plate; Then it flows into the filter bag, and a large amount of dust remains on the filter bag; Some dust directly falls into the ash hopper through the lower flower plate, and the air flow is purified through the filter bag. The purified air flow enters the induced draft fan through the exhaust valve and is discharged into the atmosphere
