Describe the present invention in detail below in conjunction with accompanying drawing, accompanying drawing has been represented a preferred embodiment of the present invention.Wherein,
Fig. 1 is the stereogram of fluid bed of the present invention, has cut a part of wall wherein open;
Fig. 2 is the cross sectional view of this fluid bed.
This intensive fluid bed comprises: in a housing 1 that is made of rigidity of soft tissues metallic plate 20 and inner concrete layer 21, three chambers are arranged:
-solid particle receiving chamber 11, solid particle imports this chamber through via hole 12;
-chamber 2, solid particle enter this chamber after crossing first wall 13;
-solid particle is discharged chamber 15, and the part of this chamber is shown among Fig. 1, and solid particle is contained in this chamber after crossing second wall 14, and this chamber has not shown solid particle tap.
The bottom that chamber 2 has fluidization air infeeds case 3, is arranged on fluidization air nozzle 4 and heat exchanger 5 on the chamber 2 diapire 2A.Heat exchanger is made of in order to the parallel pipe row who carries heat-exchange fluid (for example steam) some, and their lateral arrangement are in chamber 2 and under the roof 2B suspention of chamber 2.Heat-exchange fluid in each pipe comes the bottom and vertically is arranged on housing 1 is imported house steward 6 and is connected, the top with vertically be arranged on housing 1 in heating after fluid delivery trunk 7 be connected.
Therefore, the intensive fluidisation of solid particle and reclaim heats by heat exchanger 5 takes place in chamber 2.
Such fluid bed generally is used for the combustion apparatus that is made of Circulation fluidized-bed furnace, it has a gas vent to import in the cyclone separator, the solid particle of Shou Jiing is by aforesaid external fluidized bed the processing thus, and a part of solid particle at least wherein is ejected in the Circulation fluidized-bed furnace again.
Input house steward 6 is contained among the diapire 2A of chamber 2 and is positioned on the central plane of chamber 2.Or rather, it is accommodated in the groove 9 among the diapire 2A of chamber 2, and covers with sand or concrete 16, so that make it fix and protected.The pipe 10 that infeeds of heat-exchange fluid passes fluidisation case 3, and is connected on the input house steward 6 by t connector.
Input house steward 6 links to each other with some hairpin-shaped heat-exchange tube rows.These pipe rows with common mode be roughly flatly extend to wall 13,14 contour.Pipe is lined up over the ground and is suspended in midair by the roof 2B of two vertical support columns 17,18 from chamber 2.Two support columns link to each other with input house steward 6, pass roof 2B, and have turn back part 17A, the 18A that links to each other with delivery trunk 7.Each pipe of pipe row also all links to each other with delivery trunk 7.Support column 17,18 can be the sort of type described in French Patent (FRP) FR-2622963, is connected to by some Connection Elements on pipe row's the horizontal component, provides mechanical support and liquid flowing connection with this.Support column has constituted the extension of a certain hairpin tube.The horizontal component of hairpin tube all is isometric, and this has just eliminated the stress difference in the support column 17,18.
