Brief description of the drawings
Fig. 1 is the system block diagram of the utility model high-efficiency electric bag dust collector.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.
The utility model provides a kind of new and effective electric bag dust device, including air inlet, electrostatic precipitator, bag-type dust
Device, air inlet are designed with airflow-distribution board, and the main function of airflow-distribution board is that flue gas is shunted, and flue gas is entered electrostatic
Reach required rate request before dedusting.The airflow-distribution board of air inlet is arranged to two pieces, is respectively front and rear panels, at this time cigarette
Gas velocity degree declines faster, more preferable in the uniformity of whole electrostatic fabric filter medium velocity.Aperture is provided with airflow-distribution board, relatively
For circular hole, speed of the flue gas when process square hole speed can be than coming in is slow, and the trend successively decreased is presented in speed, can
Reach more preferable shunting function, therefore the aperture on airflow-distribution board is arranged to square hole.
Electrostatic precipitator includes corona polar line and dust collecting pole plate, and corona polar line is arranged to RS corona polar lines, because RS coronas
The corona effects of polar curve are good, and required voltage is low.Dust collecting pole plate is arranged to c-type dust collecting pole plate, and chief reason is due to that c-type is gathered dust
The specific collection area of pole plate is big, simple in structure, is easily installed and cleans.The main function of electrostatic precipitator is produced by corona discharge electrode
Electric field, makes gas ionization produce corona zone, the charged particle of ionization is attached on exhaust gas dust particle, even if dust particles lotus
Electricity, Charged particle rely on electrostatic attraction and Molecular Adsorption power under the action of electric field force to the polar motion that gathers dust, electric grit
It is gathered on dust collecting pole plate, electrostatic precipitator completes trapping to it, by deashing device, timely on deashing clearing electrode
Grieshoch.
Bag filter is a kind of dust arrester installation that dust in separation dusty gas is realized by filter material.Its dedusting
Cheng Wei：There is no any obstacle during beginning, between cloth bag and flue gas, after flue gas is directly through cloth bag, clean gas is from cloth bag
Inside discharged through air-purifying chamber, dust rests on the outside of cloth bag unit, over time, dust cloth bag unit it is more long-pending more
More, ash-laden gas will first pass through the dust film being made of dust and could be contacted with cloth bag unit, and dust film plays filtering at this moment
The effect of dust.Filter bag is the terminal control link of electric-bag complex dust collector, is the crucial portion for determining its outlet drain concentration
Part, the filtering accuracy of filter bag are directly related to soot emissions value.To ensure dust removing effects, PTFE overlay films are selected as filtrate,
PTFE coated filter materials are a kind of high-precision filtration filtrates, are the first choices of minimum discharge electric-bag complex dust collector filtrate.
The filtering of the charged dedusting of electric precipitation and bag dedusting is intercepted mechanism by electric bag dust device provided by the utility model
