Dedusting collection cylinder

The invention discloses a dedusting collection cylinder, which comprises a dust collection cylinder body, a filter device, a high-pressure air tank, a pulse solenoid valve and an air injection device, wherein an air inlet which is connected with a fan is arranged on the upper part of the dust collection cylinder body; a dust absorption inlet is formed on the lower part of the dust collection cylinder body; the filter device is arranged on a clapboard; and a dust storage part is arranged at the bottom of the dust collection cylinder body. According to the dedusting collection cylinder, when excessive dust adsorbed at the periphery of a filter cylinder reaches a certain thickness, and the flowing of air flow is influenced, operators can turn on a control switch on the upper surface of a top cover of the dust collection cylinder body, and a control circuit operates to start the pulse solenoid valve, so that the air injection device of the high-pressure air tank ejects high-pressure airflow to the filter cylinder instantly. The dedusting collection cylinder is high in ash cleaning efficiency and short in blowing time, has a good effect, and can blow to clean ash frequently without the stop of airflow.
