By using the hot ash of the coal circulating fluidized bed boiler as the solid heat carrier for pyrolysis and gasification of urban rubbish, the rubbish pyrolysis gasification device has compact structure, and can be used for harmless, reduction and resourceful treatment of rubbish.
Description
Technical field:
The utility model belongs to a kind of refuse treatment plant, particularly a kind of solid thermal carriers refuse pyrolysis gasification installation that utilizes coal CFBB heat ash as thermal source.
Background technology:
Along with the acceleration of process of modernization, the growth rate of municipal refuse quantity is accelerated, and content of organics also increases to some extent in the rubbish, and municipal refuse increases day by day to the influence of city environmental pollution, and the task of treatment of urban garbage is more and more heavier.In the conventional garbage processing method, the landfill method floor space is big, and secondary pollution is wayward; The composting process floor space is bigger, and nuisance easily exceeds standard in the fertilizer; The burning method floor space is little, and exhaust gas volumn is big, and flue gas processing device is big.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of solid thermal carriers refuse pyrolysis gasification installation is provided, and this apparatus structure compactness can be carried out garbage harmless, minimizing and recycling treatment.
The technical solution of the utility model is: a kind of solid thermal carriers refuse pyrolysis gasification installation, be characterised in that: form by coal CFBB, cyclone separator, pyrolytic gasification device and screw feeder, the high-temperature flue gas of coal CFBB and hot grey outlet are communicated with the import of cyclone separator, high-temperature flue gas is discharged at the top of cyclone separator, and the hot ash that the cyclone separator outlet is discharged enters the pyrolytic gasification device respectively and coal follows fluidized-bed combustion boiler; The import of pyrolytic gasification device also is communicated with the outlet of garbage feeding system, the using pyrolysis gasification product outlet of pyrolytic gasification device is connected with the import of screw feeder, the outlet of screw feeder is connected with the coal CFBB, and the gas discharge outlet of pyrolytic gasification device is discharged pyrolytic gasification gas.
The above-mentioned hot grey amount that directly enters the coal CFBB from the discharge of cyclone separator outlet is controlled by cycling hot ash control valve, and then controls the hot ash amount that enters the pyrolytic gasification device.
The utility model has the advantages that: utilize coal CFBB heat ash as solid thermal carriers, its heat energy is with urban refuse thermal decomposition and gasification.Gaseous product enters and can be used as the combustion gas utilization after gas cleaning device removes harmful substance, solid product together enters the stove internal combustion with hot ash, coal CFBB and refuse pyrolysis gasifier are combined into one, and compact conformation carries out garbage harmless, minimizing and recycling treatment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.Wherein: 1 is the coal CFBB; 2 is cyclone separator; 3 is the pyrolytic gasification device; 4 is screw feeder; 5 is cycling hot ash control valve.
The specific embodiment:
As shown in the figure: a kind of heat ash is the refuse pyrolysis gasification installation of solid thermal carriers, it is characterized in that: form by coal CFBB, cyclone separator, pyrolytic gasification device and screw feeder, the high-temperature flue gas of coal CFBB and hot grey outlet are communicated with the import of cyclone separator, high-temperature flue gas is discharged at the top of cyclone separator, and the hot ash that the cyclone separator outlet is discharged enters pyrolytic gasification device and coal CFBB respectively; The import of pyrolytic gasification device also is communicated with the outlet of garbage feeding system, the using pyrolysis gasification product outlet of pyrolytic gasification device is connected with the import of screw feeder, the outlet of screw feeder is connected with the coal CFBB, and the gas discharge outlet of pyrolytic gasification device is discharged pyrolytic gasification gas.Discharge the heat ash that directly enters the coal CFBB from the cyclone separator outlet and measure, and then control enters the grey amount of heat of pyrolytic gasification device by the control of cycling hot ash control valve.
The course of work of the present utility model is:
Coal is sent into coal CFBB 1 by feeding system, and air is entered bed by coal CFBB 1 bottom, burns with coal, generates high-temperature flue gas, emits a large amount of heat simultaneously.The heat that produces will enter the soft water heating of coal CFBB, produce high steam and discharge; Flue gas and the hot ash of carrying secretly enter cyclone separator 2.Heat ash enters pyrolytic gasification device 3 with after flue gas separates, and flue gas is discharged by the cyclone separator top.The heat ash that enters pyrolytic gasification device 3 contacts with the municipal refuse of being sent into by the garbage feeding system after treatment, heat by the heat ash makes urban refuse thermal decomposition, and the steam that municipal refuse and pyrolytic gasification device 3 bottoms are fed gasifies generation gaseous product and solid product.Pyrolytic gasification gas is discharged by pyrolytic gasification device 3 tops; Be advanced into screw feeder 4 under the solid product.Screw feeder 4 is sent the heat ash and the using pyrolysis gasification product of high temperature into coal CFBB 1.The lime-ash that coal CFBB 1 produces is discharged by the bottom, finishes the circulation of material.The heat ash amount that enters pyrolytic gasification device 3 is by 5 controls of cycling hot ash control valve.
