Description
Technical field
The present invention relates to a kind of equipment that utilizes filter bag to remove dust in the ash-laden gas, especially a kind of pulse long-cloth-bag duster.
Background technology
At present, sack cleaner is widely used in industries such as electric power, cement, metallurgy, chemical industry.The basic structure of this class deduster comprises housing, filter bag, ash bucket, anti-blow cleaning dust device.The top of housing is provided with air outlet, the internal upper part of housing is provided with upper face plate, the bottom of housing is a lower face plate, filter bag is arranged between upper face plate and the lower face plate, ash bucket is arranged on housing bottom, the anti-blow cleaning dust device is arranged on the top of housing, the front end face of housing is provided with air inlet, it is positioned at a side of front end face, the interior air channel of air inlet and wedge structure links, it above the interior air channel inclined-plane, it is shaped as rectangle, both sides, interior air channel are right angled triangle, being that the two sides of right angled triangle is perpendicular with both sides above the interior air channel, is air outlet below the interior air channel, it is shaped as rectangle.Enter the interior air channel of sphenoid from air inlet when dusty gas after, dusty gas moves downward from the air outlet in interior air channel and rushes at ash bucket bottom, collides that the back changes the direction of motion, dusty gas moves upward with it.The dusty gas that moves upward through lower face plate enter filter bag, gas passes filter bag, dust is delayed at the filter bag inner face, dusty gas is purified.Purified gas enters exhaust zone through upper face plate and is discharged from air outlet by the air draft blower fan.Because dusty gas rushes at ash bucket and collides with it from the air outlet in interior air channel, this can make the dust of collecting in the ash bucket raise up with higher speed, in the service life that has so not only increased the load of filter bag but also made the filter bag excessive wear, reduce filter bag, the while also has a strong impact on the dust removing effects of deduster.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of pulse long-cloth-bag duster, and this deduster is the efficiency of dust collection height not only, and life of bag filter is long.
The technical solution adopted for the present invention to solve the technical problems is: it contains housing, ash bucket, filter bag, upper face plate, the anti-blow cleaning dust device, ash bucket is arranged on the below of housing, the front end face of housing is provided with air inlet, upper face plate is arranged on the internal upper part of housing, the suitable for reading of filter bag is arranged on this plate, described air inlet is positioned at the central authorities of housing front end face, described upper face plate is positioned at the both sides of housing internal upper part, the upper face plate top that is positioned at both sides is provided with exhaust air box, the rear end face of exhaust air box is provided with air outlet, the anti-blow cleaning dust device is by pulse valve, air accumulator, blast tube and nozzle constitute, nozzle is arranged on the blast tube, air accumulator is arranged between the exhaust air box, one end of blast tube is arranged in the air accumulator and with the pulse valve that is arranged on this jar and links, the other end of blast tube is positioned at exhaust air box, nozzle on it is positioned at filter bag top suitable for reading, nozzle quantity is identical with filter bag quantity, be provided with support in the filter bag, support is the cage structure shape, it is by stock, annular ring constitutes, stock is arranged on around the annular ring, the upper end of support is arranged on the upper face plate, and the end opening of filter bag is sealed by filter cloth.
Be provided with deflector between the front side of described air inlet and filter bag.
Described filter bag is at the stairstepping that is arranged in of upper face plate.
Described ash bucket is the ship shape planform, and its inclination angle is greater than 60 °, and the ash bucket inner surface is arc surface for four jiaos and connects.
Central authorities, the filter bag that the import of above-mentioned deduster is positioned at the housing front end face is positioned at the top that enclosure interior both sides, exhaust air box are positioned at upper face plate.When dust-contained airflow when air inlet enters enclosure interior, at first enter in the space between the filter bag and and spread to both sides, dust-contained airflow then passes filter bag, dust is delayed at the outer surface of filter bag, dusty gas is purified, and purified gas enters in the filter bag, enter exhaust air box through upper face plate is discharged from air outlet by the air draft blower fan.Direction in the housing does not change because dust-contained airflow enters, air-flow flow to smooth and easyly, be in negative pressure state in the housing simultaneously.Therefore the dust-contained airflow that enters from air inlet can not rush at the phenomenon that ash bucket also collides with it.This has not only reduced the load of filter bag, and has reduced the wearing and tearing of filter bag, the service life of improving filter bag, has also improved the efficiency of dust collection of deduster simultaneously.The anti-blow cleaning dust device is made of pulse valve, air accumulator, blast tube and nozzle, and the compressed air that air accumulator provides is by the strength of the blowback wind in the nozzle spirt filter bag, and the blowback wind-force amount that provides more than the prior art blower fan is big, so deashing is thoroughly reliable.Be provided with deflector between air inlet and the front side filter bag, make the air-flow that enters in the housing even.Filter bag makes the air-flow that enters in the filter bag more even at the stairstepping that is arranged in of upper face plate, helps improving efficiency of dust collection.Ash bucket is the ship shape planform, and its inclination angle is greater than 60 °, and the ash bucket inner surface is arc surface for four jiaos and connects, and this effectively prevents the dust stratification of ash bucket.
