Abstract
The present invention relates to a kind of collection case apparatus with static pressure self-balancing for CFB boiler.Header is connection heat absorption tube bank and the structure of conveyance conduit, but due to hydrostatic pressure is distributed in header difference will lead to heat absorption restrain in fluid distrbution it is uneven.The present invention changes the intrinsic static pressure distribution of header by unicom pipeline, and then changes the flow distribution of working medium in heat absorption tube panel.It includes: header ontology (1), communicating pipe (2), fixed device (3), conveyance conduit (4) and heat absorption tube panel (5) that it, which is formed,.It is characterized in that unicom pipeline is built in header ontology, one end connect with conveyance conduit and passes through fixed device and fixes, and the other end is connect with end heat absorption tube panel.
Description
Technical field
The present invention relates to a kind of collection case apparatus with static pressure self-balancing for CFB boiler.
Background technique
The final stage heating surface of circulating fluidized bed boiler (CFB) is arranged in inside burner hearth, using the heat absorption tube panel structure of L-type.
Since medium temperature is higher in curtain wall, in order to guarantee that safe operation needs to export medium between different pipes in control flow
Temperature deviation, control temperature deviation key be exactly control heat absorption tube panel in working medium assignment of traffic；But by header (pipe
Son and the connection structure of pipeline) itself Static compression performance influence, leading to the flow of medium in pipe, there are deviations.
Summary of the invention
The purpose of the present invention is to solve the above-mentioned problems of the prior art, and then provide a kind of for CFB boiler
The collection case apparatus with static pressure self-balancing；In order to reduce the flow deviation for shielding interior pipe, the present invention uses the form of cross over pipe,
The static pressure deviation in header is balanced, achievees the purpose that reduce and shields interior flow deviation.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of collection case apparatus with static pressure self-balancing for CFB boiler, including header ontology, communicating pipe, fixed dress
Set, conveyance conduit and heat absorption tube panel, described communicating pipe one end is placed in header ontology, and is connected to and is led to conveyance conduit
It crosses fixed device to fix, communicating pipe other end lower section is connect with heat absorption tube panel jointly with header ontology lower section.
The beneficial effects of the present invention are: there is the connection pipe device of balance static pressure by using technical solution of the present invention
The intrinsic static pressure distribution of header can be changed by connecting pipe, and then change the flow distribution of working medium in heat absorption tube panel, put down
Static pressure deviation in the header that weighs reduces flow deviation in shielding.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is header static pressure situation distribution schematic diagram of the present invention.
Fig. 3 is that fluid present invention moves towards schematic diagram.
Specific embodiment
Below in conjunction with attached drawing, the present invention is described in further detail: the present embodiment is being with technical solution of the present invention
Under the premise of implemented, give detailed embodiment, but protection scope of the present invention is not limited to following embodiments.
As shown in Figure 1, a kind of collection case apparatus with static pressure self-balancing for CFB boiler involved in the present embodiment,
Including header ontology 1, communicating pipe 2, fixed device 3, conveyance conduit 4 and heat absorption tube panel 5, described 2 one end of communicating pipe is placed in
In header ontology 1, and it is connected to conveyance conduit 4 and is fixed by fixed device 3,2 other end of communicating pipe lower section and header ontology 1
Lower section is connect with heat absorption tube panel jointly.
As shown in Figure 2 and Figure 3, static pressure right low left high in header is changed in header ontology by the setting of communicating pipe 2
Static pressure distribution, the pipe diameter size of communicating pipe can be changed according to actual needs, and then change the heat absorption tube panel connecting with communicating pipe
The flow of interior working medium realizes the purpose of flow distribution in adjustment heat absorption tube panel.
The principle for balancing static pressure is as follows:
1, it for conventional header, is constantly split when working medium flows in header along flow direction, leads to axial velocity
Constantly decline, dynamic pressure constantly reduces and static pressure is continuously increased.Heat-exchanging tube bundle entrance is connect with header, not due to static pressure distribution
, lead to the unevenness of flow distribution and the flow deviation of header entrance area and exit region is maximum.
2, by realizing being directly connected to for header entrance area and exit region communicating pipe, balance entrance exports the present invention
The static pressure in region reduces flow distribution deviation.
3, in addition the present invention can also adjust header and the circulation of communicating pipe hinders by choosing different connection pipe sizes
Power, and then change the assignment of traffic of communicating pipe and header, the working medium flow at control heat absorption tube panel both ends.
The foregoing is only a preferred embodiment of the present invention, these specific embodiments are all based on the present invention
Different implementations under general idea, and scope of protection of the present invention is not limited thereto, it is any to be familiar with the art
Technical staff in the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of, should all cover of the invention
Within protection scope.Therefore, the scope of protection of the invention shall be subject to the scope of protection specified in the patent claim.
