Specific embodiment
More describe the technical solution of the utility model in detail below by embodiment, but protection domain is not limited thereto.
The drying equipment related in following embodiment, can select equipment disclosed in the patent of invention of another " one way of life garbage drying equipment " by name.
The bar-producing machine related in following embodiment, can use the bar-producing machine announced in the patent of invention of " one way of life rubbish system rod equipment " by name.
The heat-exchanger rig related in following embodiment, is shown in the utility model patent of another " one way of life refuse pyrolysis gas firing heat-exchanger rig " by name.
embodiment: RDF burning electricity generation system prepared by a kind of clean and effective rubbish, as shown in Figure 1, garbage sorting machine 1, garbage pulverator 2, house refuse drying equipment 3, bar-producing machine 4, additive adding apparatus 5, combustion chamber 6, hot gas heat-exchanger rig 7, steam-driven generator 8, construction material Preparation equipment 9, tempering room 10 and vent gas treatment pond 11 is comprised; The organic matter outlet of described garbage sorting machine 1 connects the feeding mouth of garbage pulverator 2 by conveying device, the metal outlet of garbage sorting machine 1 connects recovery place 12 by conveying device, and the inanimate matter outlet of garbage sorting machine 1 is by conveying device connecting building material Preparation equipment 9; The discharging opening of garbage pulverator 2 connects the feeding mouth of house refuse drying equipment 3 by conveying device, the discharging opening of house refuse drying equipment 3 connects the feeding mouth of bar-producing machine 4 by conveying device, the moisture discharge pipe of house refuse drying equipment 3 passes into vent gas treatment pond 11; The feeding mouth place of bar-producing machine 4 is also provided with additive adding apparatus 5, and the discharging opening of bar-producing machine 4 connects the feeding mouth of combustion chamber 6 by conveying device; The slag notch of combustion chamber 6 passes through by conveying device connecting building material Preparation equipment 9, and the heating pipe of combustion chamber 6 connects the hot gas inlet of hot gas heat-exchanger rig 7; The steam pipe of hot gas heat-exchanger rig 7 connects the steam inlet of steam-driven generator 8, and the offgas duct of hot gas heat-exchanger rig 7 connects the air intake of tempering room 10, and the gas outlet of tempering room 10 connects the dry hot gas inlet of house refuse drying equipment 3 by pipeline; After the Low Temperature Steam that steam-driven generator 8 is discharged is condensed into liquid in the coiled pipe that water pipe is passed into hot gas heat-exchanger rig 7.Vent gas treatment pond 11 is Calcified pond, and conveying device is belt feeder.
Operation principle: crude waste is categorized into organic matter, metal and the inanimate matter except metal by garbage sorting machine 1, organic matter is delivered to garbage pulverator 2 through conveying device and pulverizes, metal is delivered to recovery place 12 through conveying device and recycles, and the inanimate matter except metal is transported to construction material Preparation equipment 9 and makes construction material.House refuse after pulverizing is delivered to house refuse drying equipment 3 through conveying device and carries out drying, and the moisture (foul smell) that dry house refuse generates is passed into vent gas treatment pond 11 and carries out disinfection deodorizing.Dried house refuse is transported to bar-producing machine 4, and additive-adding device 5 adds the additive that desulfurization depickling promotes bonding in bar-producing machine 4, and mixed material (being mixed with the granulated garbage of additive, fragment) is made bar-shaped RDF by bar-producing machine 4.RDF bar is delivered to combustion chamber 6 and burns by conveying device, and produced slag of burning away the refuse is transported to construction material Preparation equipment 9 and made high-quality brick.Hot gas combustion chamber 6 being burned RDF bar gained is passed into hot gas heat-exchanger rig 7, and the water in the coiled pipe of hot gas heat-exchanger rig 7 is heated and flashes to vapours, and vapours is led to steam-driven generator 8 and generated electricity.Hot gas becomes waste heat gas after being absorbed a part of heat by hot gas heat-exchanger rig 7, waste heat gas is generally also in higher temperature, be directly used in drying and even can light rubbish, and rubbish itself can produce biogas, it is very dangerous for utilizing high-temperature gas to carry out drying.So, waste heat gas is passed into after tempering room 10 is adjusted to suitable temperature and passes into house refuse drying equipment 3 again, utilize the heat energy of waste heat gas to carry out drying to house refuse, take full advantage of the heat energy of waste heat gas, avoid high-temperature gas to be directly discharged in air and cause greenhouse effects.Owing to pulverizing the suction-operated of rear rubbish, flue gas without discharge, effectively avoids the secondary pollution of flue gas substantially.After the Low Temperature Steam that steam-driven generator 8 is discharged is condensed into liquid, in the coiled pipe that water pipe is passed into hot gas heat-exchanger rig 7, (water pipe connects the feed water inlet of hot gas heat-exchanger rig) provides water source for heat-exchanger rig 7 produces vapours, make water, vapour replace conversion cycles utilize, hot water more easily gasifies as steam, also further saves the heat energy needed for generating steam.
The foregoing is only preferred embodiment of the present utility model, be not limited to utility model, although be described in detail wooden utility model with reference to previous embodiment, for the technical staff in wooden field, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within all spirit in utility model and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in utility model.
