Description

Novel durable self-cleaning pulse dust collector

Technical Field

The utility model relates to a pulse dust collector technical field specifically is a novel durable self-cleaning pulse dust collector.

Background

The pulse dust collector is an improved novel high-efficiency pulse dust collector on the basis of MC-I type. High purification efficiency, large gas treatment capacity, stable performance, long service life of a filter bag, convenient operation, small maintenance workload and the like. 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. Therefore, dust accumulated on the filter bag is periodically and pulse-sprayed to remove ash, purified gas normally passes through the filter bag, and the operation of a dust removal system is ensured.

In the prior art, the filter cloth bag is mostly sprayed through a water column, so that water waste is caused, and the service life of the dust remover is shortened. Therefore, a novel durable self-cleaning pulse dust collector is provided.
