The invention discloses a
single pulse bag type
dust collector, which is characterized by including an upper box body, a middle box body and a lower box body. An air outlet and a flip top cover are arranged on the upper box body; and a dust cleaning
system is arranged in the upper box body. The middle box body is provided with a tubesheet and filter bags. The lower box body is provided with an air inlet and an overhaul door, and the hopper is arranged below the lower box body. The dust cleaning
system comprises a gas tank, an outlet
pipe, a plurality of pulse valves and blowing tubes, which are connected sequentially, and a
pulse control instrument in
signal connection with the pulse valves; and the air inlet is provided with an
airflow homogenizing device. The invention has the beneficial effects that: the pulse blowing mode for cleaning dust has the advantages of good cleaning effect, high purification efficiency, long service life of the filter bags, small
workload for repair, and safe and reliable operation; and the
airflow homogenizing device is arranged at the air inlet to slow down the
airflow entering the hopper, so as to isolate large particles conveniently as well as effectively reduce pressure loss of the
dust collector.
