LFEF Fiberglass Bag Dust Collector
Cangzhou Jinding Environmental Protection Equipment Co., Ltd. specializes in the production ofLFEF Fiberglass Bag Dust Collector, LFEF Fiberglass Bag Dust Collector is a new product developed for high - temperature flue gas dust removal. This machine adopts PLC control by microcomputer, room - by - room reverse blowing, timed and resistance - based ash cleaning, temperature detection and display measures, enabling the fiberglass bag dust collector to operate efficiently and stably in high - temperature waste gas dust removal. The emission concentration at the chimney outlet is lower than the national standard of100mg/Nm3 (it can reach≤50 mg/Nm3).
The LFEF fiberglass bag dust collector can change bags in different rooms without shutting down. It is simple to operate, safe and reliable, with low operating costs. It is an effective equipment for solving high - temperature flue gas dust removal. Now this dust collector has been large - scale serialized and is suitable for the purification of high - temperature, high - humidity and corrosive gases from submerged arc furnaces, calcium carbide furnaces, rotary kiln tails, etc.
The LFEF fiberglass bag dust collector consists of a dust - containing gas inlet to a purified flue gas outlet. The main body structure is composed of an intake pipeline, an intake chamber, a bag chamber, an ash hopper, an ash discharge valve, an outlet pipeline, a reverse - blowing system and an ash - cleaning control system.
The main body of the LFEF fiberglass bag dust collector is made of all - steel structure, and is designed with heat - expansion prevention measures. The outer shell is double - layer insulated with lightweight rock wool boards, and the outer surface usesδ=0.5Galvanized steel plate protection, and a new process of pull rivets is used for installation. The flower plate is formed by cold stamping, rolling and calendering processes, which not only increases the strength but also ensures the equipment quality.
LFEF-type fiberglass bag filter uses specially treated high-temperature resistant fiberglass filter bags, which have good folding resistance, wear resistance, strength and thermal shock performance,and the fiberglass can be treated correspondingly according to different flue gas characteristics to meet the user's requirements and emission standards.
LFEF-type fiberglass bag filter working principle

After the dust collector runs for a period of time, the dust layer collected on the inner surface of the filter bag thickens, and the operating resistance of the dust collector rises. When it increases to a certain value, the filter bag needs to be cleaned, that is, the dust attached to the inner surface of the filter bag is removed by external force, so that the operating resistance of the dust collector decreases. After the resistance decreases to a certain value, the filter bags in this chamber are put into normal operation again.
The entire ash cleaning process is mainly carried out through reverse air blowing. When the resistance rises to the point where ash cleaning is required, the microcomputer instructs to close the exhaust valve and open the reverse air blowing valve. The originally expanded dust filter bags are compressed and deformed under the action of reverse air blowing, so as to achieve the purpose of cleaning the dust attached to the inner surface of the filter bags. The cleaned ash falls into the ash hopper, enters the ash conveying mechanism through the ash discharge valve and is discharged. The entire ash cleaning process is carried out alternately in each chamber without affecting the normal operation of the dust collector.
Timed ash cleaning is carried out according to the time program. Each chamber automatically performs alternate ash cleaning according to the adjustable time parameters. The ash cleaning cycle of the dust collector can be set and adjusted according to the process requirements.
The flue gas temperature generally fluctuates in the range of60～300℃, and the moisture content of the flue gas is about in the range of4～12%. In order to prevent the condensation and bag pasting of the dust collector and the occurrence of malignant accidents such as bag burning due to excessive temperature, the following measures are specially taken:
(1) The intake pipe, body and ash hopper of the bag filter should be insulated to prevent the dust collector from condensing.
(2) Temperature detection and automatic alarm devices are installed at the intake and exhaust ports of the dust collector. Once the exhaust gas exceeds the operating temperature range of the dust collector, an alarm will be issued and temperature control measures will be automatically taken to ensure the safe operation of the dust collector.
