precipitator product description
The dust catcher is a new type of high-efficiency dust catcher
researched, developed and produced by our company after digesting
and absorbing the advantages of various dust catcher from abroad.
This type of dust collector combines the advantages of chamber
blowing and pulse blowing and other types of dust collectors,
overcomes the disadvantages of insufficient kinetic strength in
chamber blowing and simultaneous blowing and pulse filtration and
dust cleaning, which makes the bag dust collector more adaptable to
use, improves the efficiency of dust removal and prolongs the
service life of the filter bag. It is characterized by strong
dust-cleaning ability, high dust removal efficiency, low emission
concentration, etc. It is especially suitable for dealing with
waste gas with high dust concentration (1000g/m³). And it is widely
used in electric power, cement, metallurgy, chemical industry,
mining, ceramics and other industries in a variety of flue gas dust
treatment needs.precipitator working principle
The dust collector adopts the structure of lower inlet chamber.
Dust-containing flue gas enters into the dust hopper from the air
inlet; some larger dust particles fall into the dust hopper
directly due to inertial collision, natural settlement and other
roles, and other dust material rises with the airflow into the
various bag chambers. After filtering by the bag, the dust
particles are blocked on the outside of the bag, and the purified
gas enters the box from the inside of the bag and is discharged
into the atmosphere through the lifting valve and the air outlet.
The dust in the dust hopper is discharged from the screw conveyor
and separating wheel at regular intervals or continuously. As the filtration process continues, the
dust attached to the outside of the filter bag increases, which
leads to a gradual increase in the resistance of the dust collector
itself. When the resistance reaches the pre-set value, the dust
controller sends out a signal, first of all, make a bag room
lifting valve closes to cut off the filtering airflow of the room,
and then open the electromagnetic pulse valve, as well as a short
period of time (0.1-0.2 seconds) to the box sprayed into the
compressed air of 0.5-0.7Pa. The compressed air expands at a high
speed in the box, causing the filter bag to produce high-frequency
vibration deformation, coupled with the role of the reverse
airflow, so that the outside of the filter bag attached to the dust
cake deformation and fall off. After fully considering the settling
time of the dust (to ensure that the dust can effectively fall into
the dust hopper), the lifting valve opens, the bag chamber again
into the filtration state, and the next generation of chamber into
the cleaning state, so a cycle.PPCS air box pulse bag dust
collector is composed of a number of independent chamber, cleaning
the dust chamber in order to be carried out separately. They do not
interfere with each other and realize long-term continuous
operation.
The above dust-cleaning process is
automatically controlled by the dust-cleaning controller (PLCFw),
which is of two types, namely, timed type and fixed resistance
type, and can be decided according to the user's requirements.
Basic structure:
The main structure of the dust collector
consists of four parts: box, bag, ash hopper, air inlet and outlet.
And it is equipped with foundation pillars, climbing ladder,
railing, access door, compressed air gas circuit system, ash
cleaning control system, ash unloading system, etc. Advanced
equipment operation monitoring system and ash unloading and
conveying system can be selected according to the user's
requirements.
