The implementation principle of the pulse dust collector provided by the embodiment of the utility model is as follows: the dust-containing gas enters the buffer chamber 4 through the air inlet pipe 5, firstly hits the side plate of the buffer chamber 4 and the bottom plate of the ash accumulation bucket 2, the airflow turns to flow inwards along the inclined surface of the bottom plate of the ash accumulation bucket 2, and the airflow speed is slowed down. Because of the inertia effect, coarse particle dust in the gas directly falls into the bottom plate of the ash accumulation hopper 2 to play a role in pre-dust collection. The air flow entering the hopper 2 is then folded up through the filter bag with the metal skeleton inside and trapped on the outer surface of the filter bag. The purified gas enters a cleaning chamber at the upper part of the filter bag chamber and is collected into an air outlet for discharge. In the process of purifying the dust-containing gas through the filter bag, more dust is accumulated on the filter bag along with the increase of time, and the resistance of the filter bag is increased, so that the treatment air quantity is gradually reduced. For proper operation, the resistance is controlled within a certain range (140-170 mm water column), and the filter bag must be cleaned once the resistance exceeds the range. When ash is removed, the pulse control instrument sequentially triggers the control valves to open the pulse valves, compressed air in the air bag is sprayed into the corresponding filter bags through the venturi tubes by the holes of the jetting tubes, the filter bags are rapidly expanded instantly, dust accumulated on the surfaces of the filter bags is removed, and the filter bags are restored to an initial state. The cleaned dust falls into the dust hopper 2. Correspondingly, in the process that dust-containing gas enters the dust hopper 2, the dust hopper 2 bottom plate arranged on the inclined plane can play a role in guiding dust-containing air blown out of the buffer chamber 4, so that dust on the bottom plate rolls into the dust collecting groove 7 at the lower end under the blowing of air flow, when the dust in the dust collecting groove 7 is accumulated to a certain amount, the driving motor 61 is started to drive the feeding screw 62 to rotate, and the rotation of the feeding screw 62 drives the dust to be conveyed to the dust outlet 8 side, so that the dust is discharged from the dust outlet 8.

The above embodiments are not intended to limit the scope of the present utility model, so: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
