Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
Two-tube or the multi-flue chimney flue gas emission schematic diagram that Fig. 2 provides for the present embodiment, two-tube or the multi-flue chimney flue gas emission that the present embodiment provides is two-tube in tradition or improvement that multi-flue chimney flue gas emission basis is carried out, on horizontal flue 2 mouthfuls of opposites, between two smoke exhaust barrel 1 vertical sections, flue gas intercommunicating device 4 is set, by two smoke exhaust barrel 1 UNICOMs.When separate unit boiler operatiopn or the non-oepration at full load of multiple stage boiler, the flue gas that former single horizontal flue enters, by after the shunting of this flue gas intercommunicating device 4, discharges instead by two smoke exhaust barrel simultaneously, and flue gas flow rate reduces, and flue gas resistance declines.
Composition graphs 3, as preferably, flue gas intercommunicating device 4 and smoke exhaust barrel 1 junction are provided with telescopic joint or compensator 5, effectively absorb vibrations between smoke exhaust barrel 1 and flue gas intercommunicating device 4 and flexible.
As preferably, be provided with pressure sensitive self-interacting type baffle door 6 in flue gas intercommunicating device 4, automatically regulate the smoke discharge amount between each smoke exhaust barrel by pressure indication.
Composition graphs 4 and Fig. 5, pressure sensitive self-interacting type baffle door 6 comprises doorframe 6-1, and the multiple damper 6-3 be fixed on by rotating shaft 6-2 in doorframe 6-1, baffle plate 6-3 are at least two panels, doorframe 6-1 side is provided with the executing agency of the angle for controllable register 6-3.
The front and back end flue gas path of baffle plate 6-3 arranges flue gas pressures sensor, and flue gas pressures pressure sensor is connected with executing agency.Using the pressure reduction of both sides flue gas pressures inductor as the triggering signal of executing agency, the angle of controllable register 6-3, the flue gas pressures of automatic controllable register both sides, thus reach the object of flue gas shunting UNICOM.
The concrete grammar that baffle angle regulates is as follows: recover initial position when flue gas pressures sensor and baffle plate executing agency power up, i.e. level 0 degree, the flue gas pressures sensor of both sides per minute compares pressure reduction, when pressure reduction is greater than 20Pa, executing agency drives baffle plate to the direction rotational angle making pressure reduction reduce 10 degree, receives pressure difference signal next time, when pressure reduction is less than or equal to 20Pa after rotation, executing agency is failure to actuate, and baffle plate is stable at last angle position.
Pressure sensitive self-interacting type baffle door 6 can regulate aperture automatically according to the pressure differential of front and back end, realizes flue gas shunting, can effectively avoid fume emission between two smoke exhaust barrel unbalanced between two-tube or multitube fume emission cylinder in communication path.
