Description
Technical field
The utility model relates to the convection bank device in a kind of heat source boiler.
Background technology
Because heating plant exit gas temperature is generally at 250 DEG C-280 DEG C, exhaust gas temperature is too high, and main cause is less owing to manufacturing and designing convection bank heating surface area, layout is unreasonable, in addition the fouling of longtime running flue dust is serious, and cause boiler exhaust gas heat loss comparatively large, the thermal efficiency is on the low side.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, provides the device of the convection bank in a kind of heat source boiler.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
Convection bank device in a kind of heat source boiler of the utility model, it comprises upper collecting chamber, described upper collecting chamber is communicated with described first convection tube header by described water-cooling wall, described first convection tube header is communicated with described second convection tube header by the first convection tube, described second convection tube header is communicated with the 3rd convection tube header by the first tube connector, described 3rd convection tube header is communicated with the 4th convection tube header by described second convection tube, described 4th convection tube header is communicated with the 5th convection tube header by the second tube connector, described 5th convection tube header is communicated with the 6th convection tube header by the 3rd convection tube, described 6th convection tube header is communicated with down-pipe by the 3rd tube connector.
Helix fin is installed additional outside every root convection bank, change former single tube convection tube into three groups of convection banks, often organize two ends and install header additional, upper lower header tube connector connects, can reduce the heat loss due to exhaust gas of boiler, improve the thermal efficiency of boiler, the utility model adopts the convection bank of helix fin formula, boiler export flue-gas temperature can be made to reduce by 80 DEG C ~ 100 DEG C than single hose convection bank, and thermal power improves about 10%.
The beneficial effect that the utility model reaches is:
When the high-temperature flue gas of furnace outlet flows through helix fin convection bank, the heating surface of corresponding increase convection bank, thermal power can improve about 8MW than single tube convection bank.The all right disturbance flue gas of helix fin, change flue gas trend, reduce flow resistance simultaneously, alleviate the wearing and tearing of heating surface, alleviate convection bank outer wall dust stratification.Before improving, in convection bank, water head allocation is uneven, exist flow velocity slowly/heat-transfer effect is poor, and lower header is uniformly distributed 10* Φ about 108/ to be communicated with in helix fin convection bank group, water head allocation is even, flow velocity is even, have a narrow range of temperature, heat-transfer effect is good, the vaporization of managing interior water can also be prevented simultaneously, improve the security of boiler operatiopn.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, convection bank device in a kind of heat source boiler of the utility model, it comprises upper collecting chamber 1, described upper collecting chamber 1 is communicated with described first convection tube header 3 by described water-cooling wall 2, described first convection tube header 4 is communicated with described second convection tube header 5 by the first convection tube 4, described second convection tube header 5 is communicated with the 3rd convection tube header 7 by the first tube connector 6, described 3rd convection tube header 7 is communicated with the 4th convection tube header 9 by described second convection tube 8, described 4th convection tube header 9 is communicated with the 5th convection tube header 11 by the second tube connector 10, described 5th convection tube header 11 is communicated with the 6th convection tube header 13 by the 3rd convection tube 12, described 6th convection tube header 13 is communicated with down-pipe 15 by the 3rd tube connector 14.
Helix fin is installed additional outside every root convection bank, change former single tube convection tube into three groups of convection banks, often organize two ends and install header additional, upper lower header tube connector connects, can reduce the heat loss due to exhaust gas of boiler, improve the thermal efficiency of boiler, the utility model adopts the convection bank of helix fin formula, boiler export flue-gas temperature can be made to reduce by 80 DEG C ~ 100 DEG C than single hose convection bank, and thermal power improves about 10%.
When the high-temperature flue gas of furnace outlet flows through helix fin convection bank, the heating surface of corresponding increase convection bank, thermal power can improve about 8MW than single tube convection bank.The all right disturbance flue gas of helix fin, change flue gas trend, reduce flow resistance simultaneously, alleviate the wearing and tearing of heating surface, alleviate convection bank outer wall dust stratification.Before improving, in convection bank, water head allocation is uneven, exist flow velocity slowly/heat-transfer effect is poor, and lower header is uniformly distributed 10* Φ about 108/ to be communicated with in helix fin convection bank group, water head allocation is even, flow velocity is even, have a narrow range of temperature, heat-transfer effect is good, the vaporization of managing interior water can also be prevented simultaneously, improve the security of boiler operatiopn.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
