Abstract
The invention relates to a boiler dust collection device which comprises a dust collection box, wherein a flue gas inlet is formed on one side of the dust collection box and is connected with a boiler, a coiled heat absorption tube is arranged in the boiler, the top part of the dust collection box at the flue gas inlet is provided with a flue gas guide wall, water spray pipes are arranged in the dust collection box below the flue gas guide wall, a plurality of spray pipes are correspondingly arranged below the water spray pipes and are connected with injection spray pipes which are fixed in the dust collection box, injection spray pipes which are arranged outside the dust collection box are connected with a steam generator, the steam generator is communicated with the boiler through a pipeline, a plurality of steam nozzles are arranged below the injection spray pipes, each steam nozzle is correspondingly matched with each spray pipe, a slope is formed on the bottom of the dust collection box, a flue gas outlet is arranged on the side of the dust collection box at the upper part of the slope, and a wastewater outlet is formed on the side of the dust collection box at the bottom of the slope. A heat source which is generated in the boiler is supplied to the steam generator, the steam generator produces water steam, and the water steam is fully contacted with flue gas to realize a dust collection purpose.
Description
Technical field
The present invention relates to a kind of dust arrester, relate in particular to dust-removing device for boiler.
Background technology
Have more dust in the flue gas in the boiler chimney, mostly adopt water spray, carry out bag-type dust; Water droplet strengthens the weight of flue dust attached on the flue dust, under the effect of weight, sinks; Fall into grey small room, reach the purpose of dedusting, but adopt the water spray dedusting; Not every water droplet can both fully contact dust, thereby efficiency of dust collection is not high, also wastes water.Therefore, need provide a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
It is high to the purpose of this invention is to provide a kind of efficiency of dust collection, dust-removing device for boiler simple in structure.
The technical scheme that the present invention adopts is:
A kind of dust-removing device for boiler comprises dust-removing box, and said dust-removing box one side is provided with gas approach; Said gas approach is connected with boiler, is provided with the endothermic tube of coiling in the said boiler, and the dust-removing box top at said gas approach place is provided with smoke guide wall; Be provided with sparge pipe in the dust-removing box of said smoke guide wall below, said sparge pipe below correspondence is provided with a plurality of jet pipes, and said jet pipe is connected with injection spray pipe; Said injection spray pipe is fixed in the dust-removing box; The said outer injection spray pipe of dust-removing box of being located at is connected with steam generator, and said steam generator is communicated with boiler through pipeline, and said injection spray pipe has a plurality of steam jets; Said each steam jet is complementary with corresponding jet pipe; Said dust-removing box bottom is provided with the slope, and the dust cleaning case side on top, said slope is provided with exhanst gas outlet, and the dust cleaning case side of bottom, said slope is provided with wastewater outlet.
Said jet pipe and steam jet are 6-15.
Said smoke guide wall be shaped as arc.
Advantage of the present invention: the thermal source that produces in the boiler is supplied with steam generator, and resource utilization is high, and steam generator produces steam, and steam and water form the particulate of big density in dust-removing box, thereby fully contact the purpose that reaches dedusting with flue dust.
