Background technology
The universal design of circulating fluidized bed device (CFBA) includes：
- circulating fluid bed reactor (CFBR), it is designed as burner, burns reactor, boiler, gasification furnace, steam hair
Raw device etc., such as disclosed in the B2 of US 6,802,890.In typical CFBR, gas (air) can be saturating by reactor
The grid-like bottom section crossed, the fluid bed of grid (grid) the support particulate matter, so-called burning charges, mainly
Fuel-based material including such as coal.This provides the property of boiling liquid to the fuel material and other components in fluid bed
Energy.
Particulate matter/the fuel mixture of inflation can improve burning process and efficiency.
Burn the air/gas fluidisation that charges are generally blown into by nozzle.Fluid bed is included on the grid simultaneously
The so-called emulsion zone domain (denseboard area) adjacent with permeable reactor bottom, and in fluid bed
The density of grain material diminishes on the top of space reactor, also referred to as the free space (freeboard area) of fluid bed.
Reative cell is generally limited by external water tube wall, and the water wall is made up of the pipe that water passes through therefrom, wherein institute
State pipe or be directly welded to one another to provide wall construction, or there is the wing or rib between the pipe portion for extending in parallel.
Because the most of which fuel material of such as coal, timber etc. includes sulphur and/or harmful substance, it is therefore desirable to suitable
When mode clean the gas that leaves reative cell.
Generally end has at least one outlet port (outlet port) to CFBR thereon, wherein the outlet port permits
Perhaps the mixture of gas and solid particle is discharged from reactor, in the separator of at least one correlation of inflow.
- separator, for example, cyclone separator, for separating solid particle (granular materials, including ash from the gas
Dirt).The modular design of this separator is disclosed in US 4,615,715.The outer wall of separator may be designed as hollow space with
Flow there through water.
- device, for by the solid particle of the separation by least one corresponding of fluidized bed exchanger (FBHE)
Ingress port (inlet port) be transferred at least one fluidized bed exchanger (FBHE) from separator.These devices can be
Pipes/ducts/passage etc..
- siphon pipe, its along from separator to the path of CFBR and/or FBHE so that the pressure between separator and CFBR
The decoupling of power (field).
- at least one fluidized bed exchanger (FBHF), it allows to produce the energy using heat, and the heat is by particle
Material is provided, for example, heated by heat transfer unit (HTU) (by pipe etc.) and increased as heat transfer medium transmission by the FBHE

- FBHE is applied to return mechanism, is used for equipped with least one ingress port and at least one outlet port, the latter
At least a portion solid particle leaves and in path in returning to circulating fluid bed reactor CFBR from FBHE.
In in the past few decades, the design of many this devices and part has been developed.
But be still present to improved constant demand, especially with regard to energy efficiency (typical volume scope：50-
600MW- electricity -), efficiency, simple structure, (data of typical reaction room are to avoid machinery and thermal and mechanical stress, tight ness rating：It is high：
30-60m, it is wide：13-40m, depth：15-40m).
The content of the invention
The present invention starts from the FBHE with chamber, including：At least one solid particle inlet port；At least one solid
Grain outlet port, itself and at least one ingress port arrangement spaced apart；For by fluidizing gas from the chamber
Bottom section be incorporated into device in the chamber；And at least one arrangement heat transfer unit (HTU) in the cavity.
The present invention includes that three structures constitute part, i.e.,
A) design and arrangement of the heat transfer unit (HTU) in fluidized bed exchanger (in the cavity),
B) design and arrangement of one or more baffle plates in the chamber and on the heat transfer unit (HTU),
C) the structure connection of the heat transfer unit (HTU) and the baffle plate.
ad a)：
Heat transfer unit (HTU) FBHE chambers vertical lower extend and
- pass through FBHE from the main flow direction in the path of ingress port to its outlet port in solid particle,
- be substantially parallel to each other,
- there is space between adjacent heat transfer unit (HTU).
Each heat transfer unit (HTU) particle flow direction extension can (single heat transfer unit (HTU) be substantially by wall-like structure
Upper flat and close design) it is best implemented with.
With reference to their orientation, this allows one group of arrangement (set) multiple heat transfer unit (HTU) in a certain distance apart from one another, so that
Space is formed between adjacent wall/panel shape heat transfer unit (HTU).In other words, the passage in such as " space/gap " is arranged in adjacent
Between heat transfer unit (HTU), stream of exit region (outlet port) of the passage also from the entrance of chamber to chamber in solid particle
Extend in dynamic/transmission direction.The master-plan of this part of FBHE is similar to chamber, and compartment is divided into by midfeather, all exists
Substantial linear extends between the ingress port and outlet port of FBHE.
Term " wall-like " refers not only to cube design with flat surfaces, and refers to the cumulative volume that each heat transfer unit (HTU) takes.
One pipe, bending (complications) is such that the center longitudinal direction axle position of the pipe in an imaginary plane, represents wall-like pattern
One embodiment.Pipe portion can extend along two of coordinate system (in same level) axially distinct directions.
This design is caused in the space/channel of solid particle in fluid bed between adjacent discrete heat transfer unit (HTU)
Flowing, i.e., flowing in the space (passage) formed between adjacent heat transfer unit (HTU), although material can pass through heat transfer unit (HTU) (example
Such as in the case where heat transfer unit (HTU) is made up of one or more bending pipes), but it is few more than main flow direction.
If discrete heat transfer unit (HTU) is the tube/conduit by bending provided, situation is especially true, such as according to following
One in optional feature：
- wall-like pattern includes network structure.This causes that solid particle flows along all directions of coordinate system, but is to maintain court
To the main transmission direction of outlet port.
- heat transfer unit (HTU) is designed to heat-exchange tube, for transmitting heat transfer medium and arranging in curved manner, so as to provide
The wall-like pattern of vertical orientation.
- multiple heat transfer unit (HTU)s arrange at a certain distance each other, form a set of/group heat transfer unit (HTU).This provides a collection of/set and passes
Thermal, through cavity volume.
- since cavity bottom or close to cavity bottom, heat transfer unit (HTU) extends the 50-90% of about chamber height.
The extension of-heat transfer unit (HTU) is approximately less than the 80% of chamber height.
- heat transfer unit (HTU) extends from slightly above bottom up.
The horizontal continuation of the heat-exchange tube of-bending is more long than the vertical extension of same heat-exchange tube at least 3 times.This
Constitute the basis of the main transmission direction of solid particle.
- heat transfer unit (HTU) can be used as reheater or superheater carrys out the biography of reheating or overheat (superthermal) in described device (pipe)
Defeated medium.

The adjacent part of-same heat-exchange tube or another heat-exchange tube of same heat conductive wall extend to external heat friendship each other
Change 0.1-4 times (or 0.5-2 times) of pipe diameter.
- inlet chamber of solid particle do not need/is not provided in FBHE and/or chamber is returned allows continuous flowing
Pattern.
Ad b)：
At least one baffle plate extends on the top of FBHE chambers, and
- heat transfer unit (HTU) is substantially perpendicular to,
- therefore substantially perpendicular to the main flow direction of the solid material between ingress port and outlet port,

Supply water to further baffle plate.
- at least one baffle plate is designed to curtain.The curtain limits baffle plate has many small, discrete openings or slit,
But the opening or slit make pressure balanced are largely avoided solid particle and pass through.
The line of-multiple the baffle plates between ingress port and outlet port is arranged at a certain distance each other, i.e. away from entering
The different distance in mouth port.
