Description
Technical field
This utility model relates to a kind of biomass recirculating fluidized bed boiler material-returning device, belongs to Sector of Cfb Boilers.
Background technology
Circulating popular fluidized bed boiler technology is the high-efficiency low-pollution cleaning burning branch art developed rapidly in recent ten years, and this technology is widely used in fields such as station boiler, Industrial Boiler and offal treatment utilizations.A large amount of high-temperature hot ash can be produced in CFBB running, but the popular fluidized bed boiler of major part circulation at present does not arranges under material returning device and takes apparatus for ash, if the high-temperature hot ash circulated in popular fluidized bed boiler not being taken out, need long time could will circulate the cooling of popular fluidized bed boiler, extend the cool time circulating popular fluidized bed boiler, waste a large amount of heat energy.
Utility model content
For solving what prior art existed technical problem, this utility model provides a kind of simple in construction, easy to use, it is possible to make full use of the biomass recirculating fluidized bed boiler material-returning device of high temperature ash waste heat.
For achieving the above object, the technical scheme that this utility model is used is biomass recirculating fluidized bed boiler material-returning device, including: material returning device, the bottom of described material returning device is provided with ash-unloading tube, it is provided with electric cinder valve on described ash-unloading tube, the bottom of described ash-unloading tube is provided with heat exchange case, the heat exchanger plate that multilamellar is obliquely installed it is provided with in described heat exchange case, the corner of described heat exchange case is provided with supporting leg, being provided with ash discharging hole bottom heat exchange case, the lower section of described ash discharging hole is provided with and pushes away ash dolly.
Preferably, described heat exchanger plate is mainly made up of heat-conducting plate and heat exchanger tube, and the bottom of described heat-conducting plate is fixed with heat exchanger tube, and described heat exchanger tube spirals layout.
Preferably, the tank wall of described heat exchange case is sandwich, is provided with heat-insulation layer in sandwich.
Preferably, entering of described ash discharging hole is additionally provided with and leads hawk between ash end and heat exchanger plate.
Compared with prior art, this utility model has following technical effect that this utility model simple in construction, easy to use, use and heat exchange case is set bottom material returning device, high temperature ash is carried out heat exchange with the heat exchanger tube in heat exchange case, make full use of the waste heat of high temperature ash, it also avoid high temperature ash simultaneously and cool down in discharge process, waste a large amount of heat energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1, biomass recirculating fluidized bed boiler material-returning device, including: material returning device 1, the bottom of material returning device 1 is provided with ash-unloading tube 2, electric cinder valve 3 it is provided with on ash-unloading tube 2, the bottom of ash-unloading tube 3 is provided with heat exchange case 4, the heat exchanger plate 5 that multilamellar is obliquely installed it is provided with in heat exchange case 4, the corner of heat exchange case 4 is provided with supporting leg 6, ash discharging hole 7 it is provided with bottom heat exchange case 4, entering of ash discharging hole 7 is additionally provided with and leads hawk 11 between ash end and heat exchanger plate, leading hawk can make ash material enter ash discharging hole smoothly, ash discharge is convenient, the lower section of ash discharging hole 7 is provided with and pushes away ash dolly 8.
Wherein, heat exchanger plate 6 is mainly made up of heat-conducting plate 9 and heat exchanger tube 10, and the bottom of heat-conducting plate 9 is fixed with heat exchanger tube 10, and heat exchanger tube 10 spirals layout.
In use, when needing the high temperature ash in material returning device is discharged, electric cinder valve is opened, high temperature ash enters heat exchange case by ash-unloading tube, high temperature ash is fallen on heat-conducting plate, and spiral and be provided with heat exchanger tube in the bottom of heat-conducting plate, heat exchanger tube continuous print, a-circle-by-a-circle spiral, until the full whole heat-conducting plate of dish, high temperature ash slowly landing on heat-conducting plate, carry out heat exchange with heat exchanger tube in the process, thus heat the liquid in heat exchanger tube or gas, absorb heat energy；High temperature ash is gradually by top heat-conducting plate landing to bottom heat-conducting plate, to complete and the heat exchange of all heat exchanger tubes, until discharging from ash discharging hole, dropping and pushing away on ash dolly, being discharged into appointed place by pushing away ash dolly.
Additionally, the tank wall of heat exchange case uses sandwich, in sandwich, it is provided with heat-insulation layer.Heat exchange case uses sandwich, can be strengthened the heat insulation effect of heat exchange case by heat-insulation layer, extends heat-exchange time, improves heat transfer effect.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, in the range of all should wrapping in this utility model.
