Description

Pulse dust collector with gas drying function

Technical Field

The utility model relates to an environmental protection equipment technical field especially relates to a pulse dust collector with gaseous stoving.

Background

When the dust-containing gas enters the dust remover from the air inlet, the dust-containing gas firstly touches the inclined plate and the baffle plate in the middle of the air inlet and the air outlet, the gas flow turns to flow into the dust hopper, and simultaneously the gas flow speed is slowed down, so that coarse particle dust in the gas directly flows into the dust hopper due to the inertia effect. The dust collection device plays a role in pre-collecting dust, the airflow entering the dust hopper is then folded upwards to pass through a filter bag with a metal framework inside, the dust is collected on the outer surface of the filter bag, the purified gas enters a cleaning chamber at the upper part of a filter bag chamber and is collected at an air outlet to be discharged, and in the process of purifying the dust-containing gas by a filter bag, the dust accumulated on the filter bag is more and more along with the increase of time, the resistance of the filter bag is increased, so that the air volume to be treated is gradually reduced, for normal work, the resistance is controlled within a certain range (140-170 mm water column), once the resistance exceeds the range, the filter bag needs to be subjected to dust removal, a pulse controller is used for sequentially triggering control valves to open pulse valves during dust removal, compressed air in an air bag is sprayed into corresponding filter bags through holes of a spray pipe through venturi tubes, the filter bags are suddenly expanded instantly, the dust accumulated on the surfaces of the filter bags is enabled to fall off, and the filter bags are restored to the initial state. The dust falls into the dust hopper and is discharged out of the machine body through the dust discharging system.

However, when the treated gas contains moisture, dust can adhere to the filter bag along with the moisture, the adhesive force is large, when the pulse valve is opened, the dust still adheres to the filter bag and is not easy to remove, and therefore, in order to solve the problems, the pulse dust collector with gas drying is provided.
