Detailed description of the invention
Do auspiciously further to state to the utility model by specific embodiment below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of refuse burning system, house refuse is regularly transported into power plant by garbage truck, after the weighbridge through being located at on-site measures, is automatically discharged into rubbish bunker 1.During production run, rubbish is picked up through driving grab bucket 4 by rubbish in the middle of rubbish bunker 1, in the middle of the burner hearth 2 then by hopper opening rubbish being poured into incinerator, by sending into burner hearth 2 combustion after the metering of stokehold belt weight coal conveyer.Water-cooled distributor and blast cap is had in lower disposed.Combustion air is divided into primary and secondary air, and the top of burner hearth 2 arranges Secondary Air and oil burner, under the effect of overfire air fan, is passed in the middle of waste heat boiler 5 by the gas of burning.First air after preheating enters emulsion zone through blast cap aperture makes fuel take fire.Secondary Air sends into burner hearth 2 by the overfiren air port layering above bed.Boiler body is discharged after the clean flue gas of a small amount of flying dust flows through superheater and back-end surfaces by upper exhaust outlet.The slag that the rubbish of boiler multifuel combustion and cinder produce after burning, releases from the slag-drip opening arranged, directly drops down onto slag cooler 3, be transported to slag storehouse, apply to brickmaking outward after cooling.
With reference to accompanying drawing 2, the high-temperature flue gas that boiler produces produces superheated steam through heating surface heat exchange, high-temperature flue gas enters Turbo-generator Set 6 through waste heat boiler 5 and generates electricity, the electricity that Turbo-generator Set 6 sends is sent to conveying electrical network through transformer, and the residue flue gas and the interior part flue gas do not entered in Turbo-generator Set 6 of waste heat boiler 5 that are not converted to electric energy enter preliminary clearning system 7.Preliminary clearning system 7 comprises the alcohol spray chamber 71 and filter chamber 72 that set gradually, alcohol spray chamber 71 and filter chamber 72 are made up of fin panel casing, not only can carry out cooling process to flue gas, and ensure that alcohol spray chamber 71 and filter chamber 72 remain on safe temperature, be not easy to cause high-temperature damage, described spray chamber comprises water tank 71a, the alcohol liquid of 7.8% ~ 10% concentration is placed with in described water tank 71a, conduit 71b is provided with in water tank 71a, conduit 71b is connected by the sprayer unit 71c be connected with water tank 71a, be provided with the effect that alcohol liquid can play deodorizing, and the pre-dedusting of the first step can be carried out, for further place mat is made in ensuing purification work in the middle of reaction tower and sack cleaner 82, and the alcohol liquid of 7.8% ~ 10% concentration can't play the effect of lighting to gas, and the effect of sterilization can be played, after entering spray chamber, gas is further filtering by filtering filter chamber, the bamboo-carbon layer 72a of some layers is provided with in the middle of filter chamber 72, two-layer bamboo-carbon layer 72a is selected in the middle of the present embodiment, a chamber 72b is arranged at intervals with in the middle of two-layer bamboo-carbon layer 72a, by the further process of bamboo charcoal, pernicious gas and dust can be made further to reduce.
Gas cleaning main system 8, gas cleaning main system 8 is made up of reaction tower, sack cleaner 82, air-introduced machine 83 and chimney 84.Half dry type neutralization reaction tower 81 selected by reaction tower.After flue dust and harmful components are reduced to the concentration of emission meeting environment permission in flue gas after purification, enter air by chimney 84.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
