Description
Technical Field
The utility model relates to a dust collecting equipment field specifically is a high-efficient energy-saving filter bag dust collector.
Background
The flue gas of the industrial furnace contains fine dust with smaller particle size, the corresponding dust remover has multiple forms, and the traditional dust remover is a sub-bin ash bucket air inlet bag type dust remover, which has the following two problems.
Disclosure of Invention
The utility model aims at solving the problems of the prior dust remover and providing a high-efficiency energy-saving filter bag dust removing device.
The utility model has the following concrete scheme: the utility model provides a high-efficient energy-saving filter bag dust collector, includes the casing, and the casing bottom is equipped with a row of a plurality of ash bucket, is equipped with the filter bag district in the casing, and the filter bag district is equipped with a plurality of row of filter bag, and filter bag open-top, every row of filter bag quantity have a plurality of, casing one side is equipped with the air intake, and the casing top is equipped with out the tuber pipe, goes out the opening intercommunication of tuber pipe and all filter bags, goes out the tuber pipe outer end and connects the air exhauster, it is used for making its lotus electricity to the dust discharge of entering to be.
The air intake is equipped with one section toper pipe, and the toper pipe macrostoma is connected with the casing, the air intake sets up in the upper end of toper pipe, and the dust passes through the diffusion of toper pipe after getting into from the air intake.
The casing top is located the intraductal a plurality of pipes that sweep of still being equipped with of air-out, sweeps a pipe one end and connects compressed air source, sweeps the socle portion and is equipped with a plurality of gas outlets, and the opening of a filter bag is aimed at to every gas outlet.
Be equipped with the grid plate between lotus electric installation and the first row of filter bag, the equipartition has a plurality of cloth wind hole on the grid plate.
The working principle of the utility model is as follows: the high-voltage constant-current discharge device is arranged in front of the filter bag area, and the high-voltage constant-current discharge device firstly charges the dust in the flue gas, so that fine particles in the dust collide and contact with each other when the flue gas flows after the dust is charged, are adhered and polymerized into large particle dust, and then enter the bag area for filtration, and a dust layer attached to the dust facing surface of the filter bag forms a loose discrete aggregation structure, so that the filtration resistance of the bag type dust collector is reduced; the loose and discrete aggregated dust enters the filter bag area and is trapped by the filter bag.
The utility model discloses following beneficial effect has: 1. the air inlet resistance is slowed down, the energy consumption of the fan is reduced, the dust cleaning period of the filter bag is prolonged, and the service life of the filter bag is prolonged; 2. the charging device is used for charging the fine particle dust so that the fine particle dust is gathered under the action of airflow, PM2.5 fine particles can be trapped, and ultralow emission is realized; 3. because homopolar charges on the dust belt can repel each other, a loose powder cake layer is formed on the surface of the filter bag, and compared with the traditional filter hole of the filter bag, the filter hole can be more sparse, the air inlet is smoother, so that the rising rate of the running resistance of the equipment is slowed down.
