The working principle of several common dust precipitators is introduced
The dedusting equipment adopts the downdraft and external filtration, and the dedusting method is pulse jet dedusting. By ash hopper dust gas inlet into the filter, through a process of ash hopper into the filtering of outdoor, coarser particles indirect fall into ash hopper, the small dust adhesion on the surface of filter bag, filter bag filter through the process after the net net gas into the air chamber, the fan vents emissions in the atmosphere. With the increase of filtration time, more and more dust accumulated on the surface of the filter bag, so that the resistance of the filter bag was obstructed, so that the air volume of disposal was also gradually reduced, and the dust collector was in a paralyzed state. In order to keep the dust off the top of the filter bag, the equipment adopts the system of cleaning dust on time without interruption. Slag discharge pulse valve control device to recover when a standard leds in order to open the pulse valve, air bags outside air pressure brake through the process of pulse valve to spray torch into the filter bag, filter bag and third contraction, is on the surface of the filter bag dust layer is shattered, resistance and airflow are reply revival, dust catcher also return wrong things.
Mining bag duster
Filter things truth below: dust gas by bottom open flange into the filter chamber, coarser particles fall into the ash bin indirectly, dusty gas through the filter bag filter, dust resistance in bag table, net net gas through the mouth to the gas chamber, by the fan into the atmosphere. When growing on the surface of the filter bag dust, program-controlled machine start, open the pulse valve, make the compressed air through a process of nozzle of filter bag stop blowing ash removal, shrink filter bag suddenly, in the reverse flow, under the influence of dub the pocket watch agile dust from filter bag into the ash bin, dust by the discharge valve. Proper ash cleaning method and ash cleaning cycle cover the ash cleaning consequences and filter bag life of this type of dust precipitator.
Cyclone dust precipitator
Cyclone after adding bypass the things truth is tangential from the entrance into the dusty gases, air flow in reversed activity at the same time, the upper and lower airflow leave a twin twist worm activity, dust in twin twist worm of separating detention respectively, coarser dust particles with backspin worm airflow to the outer wall respectively, the central departments in dust chamber separately by the bypass of the cave leads, the rest of the dust ash hopper with the downdraft. Cochlear airflow can induce fine particle dust to improve dust removal efficiency. The fine dust particles, the department of topspin cochlear flow upwards, constitute a fierce reverse under the lid on dust ring, and topspin cochlear flow all the way to bypass the upper chamber hole respectively, the inlet into the cone meet internal and external airflow, pollution by the exhaust gas after the crowd out, out of the dust into the hopper, respectively.
Single unit dust precipitator
Dust gas into the casing, through the process of air inlet into the filter chamber, coarser particles of ash hopper is indirect fall into, small particles adhesion on the surface of filter bag, dust gas filtered through the process of net gas, fan vents the atmosphere in the course. With the increase of filtration time, the dust adhering to the filter bag surface also increases, and the resistance of the filter bag also increases, which affects the dust removal efficiency. When the resistance increases to 1500-2000pa, in order to make the dust precipitator out of order, the dust on the filter bag should be eliminated on schedule. In operation, if a large amount of dust spills out of the exhaust port of the invention, that is, the cloth bag may be damaged, which needs to be replaced in real time.
5. Air box dust precipitator
Dust gas from the air inlet filter break wind box into the inclined diaphragm turned to ash hopper, gas rate slows down at the same time, because of the inertia influence, of coarse soil particle in the gas dust fall into ash hopper, small dust currents to fold into the filter chamber, dust attached on the outer surface of the filter bag, after pollution gases through net filter bag into the upper chamber, by each room clean room to collect the outlet, the dust removal system of the main fan atmosphere under the influence. Follow the increase of filtering time, more and more are deposited in the surface of filter bag, filter bag resistance by obstacles, disposal of air volume is less also, at this time should be used in real time steps of ash removal, according to the actual situation can be manually clear ash can also control is used to clean out on time. So that the resistance of the filter bag and the disposal air volume are restored and revitalized at the same time, the dust collector is used in abnormal operation.
