Description
Technical Field
The utility model belongs to the technical field of power plant dust removal, and particularly relates to a mobile water, dust and sewage collecting system of an impeller feeder.
Background
At present, coal is continuously fed onto a belt conveyor by a No. Duan Shelun coal feeder of an underground transfer station 1 of a coal discharging ditch in the coal and electricity industry. Therefore, a large amount of dust is generated in the conveying process to pollute the environment, so that workers cannot enter the site to work normally. Although the transfer station is provided with dust removing equipment, the traditional dust removing equipment is arranged on the ground, and the underground dust collection air duct is connected with the dust remover. The dust collection air duct is provided with a plurality of dust collection openings, and the dust collection openings are immovable like an air conditioner air duct. The impeller coal feeder works in a moving way, so that the fixed dust collection port cannot achieve the purpose of dust collection on a working site.
In order to solve the trouble of dust pollution, the following three dust removal modes are adopted in each power plant:
The first is bag dust removal, the bag dust remover is arranged on the upper side of the impeller coal feeder, the space on the upper side of the coal feeder is limited, the dust removal air quantity requirement cannot be met, and the dust is adsorbed on the bag under the action of negative pressure due to the fact that the humidity of raw coal dust is too high, so that the bag is hardened, and dust gas cannot be filtered. Meanwhile, the dust remover shakes to remove dust, and the dust overflows instantaneously, so that secondary pollution is caused.
And the second type is dry fog dust removal, wherein the dry fog dust removal is synchronous impeller coal feeder tracking spray dust removal. The impeller feeder sends the coal into the guide chute to raise dust, and is sprayed by dry fog, and the raw coal falls down to impact the belt to generate positive pressure and the water pressure of a spraying system is fused, so that the positive pressure dust gas and water drops in the guide chute are expanded outwards, and are instantaneously taken out of the guide chute outlet by the conveying belt, thereby causing secondary pollution. (especially, the temperature in winter in the north is low, atomized water is condensed into mud drops), the dust removal purpose can not be achieved, and two pollution is caused.
Thirdly, the foam dust removal effect is poor, secondary pollution is caused, and the cost is too high. In the development of the coal and electricity industry in China, the environmental protection requirement is gradually improved, and the environment improvement has a convenient and high requirement. In order to achieve the aim of dedusting in the actual production environment of the coal and electricity industry, a new dedusting and sewage disposal system needs to be developed.
