Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to a bag-type dust collector.
Background
When the bag-type dust collector is used for filtering gas containing dust, because the dust is accumulated on the outer surface of a dust-removing filter bag in a large quantity, static electricity is easily generated, and then ignition points are generated;
moreover, the spark catcher is arranged at the air inlet for introducing the gas containing a large amount of dust, and even if the spark catcher is used for a short time, a large amount of pollutants are attached to the spark catcher, so that the cleaning or replacing frequency is high;
furthermore, most of the existing bag-type dust collectors extinguish fire in a spraying mode, after the fire is extinguished, the dust-removing filter bag is basically and completely wetted, and the wetted dust-removing filter bag loses the original filtering function due to overlarge resistance during dust removal, namely exhaust, and can only be replaced manually;
in conclusion, the conventional bag-type dust collector is heavy in equipment maintenance work due to the structural arrangement, high in replacement cost and influenced in working efficiency.

The pressure gauge is a U-shaped differential pressure gauge.
After the dust-containing gas enters from the gas inlet 6, part of large-particle dust is separated out and falls into the dust hopper 8 under the action of inertia and gravity, the dust-containing gas is filtered by the dust-removing filter bag, the dust is retained on the outer surface of the dust-removing filter bag, and the purified gas enters the upper part of the dust-removing box 4 through the dust-removing filter bag port and is discharged from the
along with the extension of the filtering time, the dust layer on the outer surface of the dust-removing filter bag is continuously accumulated and thick, the resistance of the dust-removing equipment is continuously increased, the pressure difference of the inlet and the outlet of the dust-removing box detected by the U-shaped pressure difference meter is increased, when the pressure difference reaches a set value, the controller 5 sends out an ash-removing instruction, the valves 7 arranged on the air inlet 6, the
