LFEF glass fiber bag type dust collector
is a new product specially developed for exhaust dedusting of cement vertical kiln and dryer. The glass fiber bag type dust collector
adopts microcomputer control, separate blowing in the chamber, regular and constant resistance dust removal, temperature detection and display. And other measures to enable the glass fiber baghouse to perform stable and stable operation in vertical kiln and dryer dust removal. The emission concentration at the chimney outlet is lower than the 150gm / m3 emission standard (actually _ not more than 50gm / m3. The equipment can be changed in different rooms without stopping the machine. The operation is simple, safe and reliable, and the operating cost is low. It is an effective equipment to solve the dust removal of exhaust gas from vertical kiln and dryer.
Structural Features The basic structure of the glass fiber bag filter consists of 3 parts.
(1) Air intake, exhaust and backflushing system of glass fiber bag filter: Including air intake duct, air inlet chamber, backflush valve, back blow pipe, tee, exhaust valve, exhaust pipe.
(2) The bag room structure of the glass fiber bag type dust collector: including ash hopper, maintenance door, body frame, upper and lower flower plate, filter bag, bag room.
(3) Ash discharge system of glass fiber bag type dust collector: including dust discharge valve and screw conveyor.
The body of the glass fiber bag-type dust collector is an all-steel structure, and the shell is insulated by a lightweight rock wool board. The flower plate adopts a new process of cold stamping and calendering, which not only increases the strength but also the quality of the equipment.
The design takes into account the thermal expansion factors and takes corresponding measures to ensure the safe operation of the equipment in the treatment of high temperature flue gas.
The working principle and performance parameters are due to the characteristics of high ash concentration, large air volume, wide pollution range, and high moisture content in the exhaust gas of the vertical kiln and dryer. It brings great difficulties to the dust removal of the dryer and vertical kiln. According to the characteristics of the dryer and vertical kiln, the upper air intake method is adopted. The dusty flue gas enters the air inlet chamber from the upper part, and some coarse particles are caused by The inertia falls into the ash bucket. When the ash is cleaned, the direction of the airflow is consistent with the direction of dust sedimentation, which prevents the secondary flying of the dust. In addition, the air inlet chamber makes the airflow uniform and the airflow speed is not abrupt, so the pressure drop of each bag chamber is balanced, which is beneficial to improve the service life of the filter bag.
In this type of glass fiber bag-type dust collector
, the exhaust valve and the anti-blowing valve are arranged at the exhaust pipe below. Dust-containing gas is sucked into the intake manifold under the action of the exhaust fan; it enters the intake chamber through each intake branch pipe; it evenly passes the upper flower plate; then it flows into the filter bag, and a large amount of dust is trapped on the filter bag; part of the dust passes directly through The lower flower plate falls into the ash hopper, and the airflow is purified through the filter bag. The purified airflow enters the induced draft fan through the exhaust valve and is discharged into the atmosphere.
