how vacuum fume extractors work generally adopts round bag, according to the direction of dust air movement is divided into side inlet air, lower inlet air, two forms, this dust collector is usually composed of upper box, middle box, ash bucket, frame and pulse blowing device part, work dust gas from the lower part of the box into the ash bucket, Due to the sudden expansion of the air flow area and the decrease of the flow rate, a part of the air flow with coarse particles and dense dust particles settle down in the ash bucket under the action of gravity. After the dust particles with fine particle size and small density enter the filter bag room, the dust is deposited on the surface of the filter bag through the inertial collision on the surface of the filter bag, screening and other comprehensive effects, and the purified gas enters the clean gas chamber and is removed by the exhaust pipe through the fan.

Here's a look at the technical features of how vacuum fume extractors work:

First, low pressure injection technology: considering the large concentration of smoke produced by the combustion of the power station boiler, the equipment resistance will increase quickly, and the frequency of cleaning will be accelerated, the use of high pressure injection will have an adverse effect on the service life of the filter bag, and the dust layer attached to the filter bag will be dispersed, which is not only conducive to the dust falling into the ash hopper with its own gravity, but also easy to cause the secondary adsorption of dust.

Through the camera probe field monitoring, the fly ash in the flue gas is relatively dry at the working temperature, and we have made the filter bag for easy ash cleaning treatment, with low pressure for ash cleaning, not only can achieve the ideal ash cleaning effect, but also can shorten the dust fall to the ash hopper time. It can avoid the phenomenon of secondary adsorption and the shortening of the service life of the filter bag due to frequent cleaning.

Second, diversion technology: electromagnetic pulse valve and filter bag are the core components of JDDM low-voltage pulse bag dust collector, and diversion is the core technology. Combined with the design concept of our company, we have taken a series of measures to promote the uniform distribution of smoke to each cloth bag, to determine the uniform load of the filter bag and extend the service life of the filter bag at the same time, to a large extent reduce the resistance of the equipment.

how vacuum fume extractors work is a kind of product with the level of how vacuum fume extractors work technology, which is integrated with the current excellent long bag off-line pulse dust removal technology. Its ontology features are as follows:

The use of separate chamber air pulse jet dust cleaning technology to overcome the shortcomings of conventional pulse dust collector and separate chamber reverse dust collector, cleaning capacity is good, dust removal rate is good, low emission concentration, small air leakage rate, less energy consumption, less steel consumption, less footprint, stable operation, good economic benefits. Suitable for metallurgy, building materials, cement, machinery, chemical, electric power, light industry dust gas purification and material recovery.

Second, due to the use of separate chamber wind pulse jet cleaning, the purpose of thorough cleaning can be achieved once, so the cleaning cycle is extended, the energy consumption of cleaning is reduced, and the pressure gas consumption can be greatly reduced. At the same time, the fatigue degree of the filter bag and pulse valve is also reduced, thereby doubling the life of the filter bag and valve disc.

Third, the maintenance and bag change can be carried out in separate rooms under the condition of non-stop system fan and normal operation of the system. Filter bag mouth with elastic ring, sealing performance is good, filter bag keel with polygonal shape, reduce the friction between the bag and the keel, extend the life of the bag, and easy to unload the bag.

4. The upper part of the bag is pumped. After the skeleton is extracted during bag changing, the dirty bag is put into the ash bucket at the lower part of the box and taken out by the manhole to improve the operating conditions of bag changing.

Five, the box adopts air tightness design, good sealing, excellent sealing materials for inspection doors, leak detection with kerosene during the production process, and the air leakage rate is very low.

6. the inlet and outlet air duct layout is compact, the airflow resistance is small.
