and the second baffle plate door is arranged in the middle of the supercharger bypass flue.
As the utility model discloses the further improvement, the condition of opening of second baffle door is: inlet flue gas pressure of the booster fan is < -1.5Kpa or inlet flue gas pressure of the booster fan is 1.5Kpa or the booster fan trips
The utility model has the advantages that: through set up the flapper door on desulfurization booster fan bypass flue for behind the shutoff of desulfurization system bypass flue, the host computer of power plant can steady operation, can overhaul desulfurization booster fan trouble simultaneously.
Drawings
Fig. 1 is a schematic structural diagram of the bypass control device of the desulfurization booster fan of the present invention.
In the figure: 1. an absorption tower; 11. an inlet; 12. an outlet; 2. cleaning a flue; 31. a first flapper door; 32. a second shutter door; 4. a chimney; 5. a boiler; 61. a first flue; 62. a second flue; 63. a third flue; 7. a booster fan; 8. the supercharger bypass flue.
Detailed Description
As shown in fig. 1, the utility model provides a desulfurization booster fan bypass control device, including absorption tower 1, chimney 4, first baffle door 31, boiler 5, booster fan 7, second baffle door 32, booster fan 7, booster compressor bypass flue 8 and second baffle door 32. The export 12 of absorption tower 1 is connected with the one end of clean flue 2, the other end and the chimney 4 of clean flue 2 are connected, first flapper door 31 is located in the middle of clean flue 2, boiler 5 is connected with the one end of first flue 61, first flue 61 is connected to the one end of second flue 62, the other end and the booster compressor bypass flue 8 of first flue 61 are connected, the other end and the entry 11 of absorption tower 1 of booster compressor bypass flue 8 are connected, the other end of second flue 62 is connected and is connected with the one end of third flue 63, the other end and the booster compressor bypass flue 8 of third flue 63 are connected, booster fan 7 is located in the middle of second flue 62, second flapper door 32 is located in the middle of booster compressor bypass flue 8.
When in specific use:
1. after entering the booster fan 7, the flue gas of the boiler 5 passes through the first flue 61, the second flue 62, the absorption tower 1, the outlet 12 of the absorption tower 1, and the clean flue 2 to the chimney 4 in sequence.
2. When the flue gas pressure of the boiler 5 is suddenly changed and abnormal, the second baffle door 32 in the booster fan bypass flue 8 is opened, and the flue gas of the boiler 5 enters the booster fan bypass flue 8 through the first flue 61, then sequentially passes through the absorption tower 1 and the outlet 12 of the absorption tower 1, and then passes through the clean flue 2 to the chimney 4.
Wherein,
when the inlet flue gas pressure of the booster fan 7 is less than-1.5 Kpa, a second baffle door 32 in the bypass flue 8 of the booster fan is opened, or,
when the inlet flue gas pressure of the booster fan 7 is greater than 1.5Kpa, the second damper door 32 in the booster fan bypass flue 8 is opened, or,
3. when the booster fan 7 is tripped due to a fault, the second baffle door 32 of the booster fan bypass flue 8 is opened, and the flue gas of the boiler 5 enters the booster fan bypass flue 8 through the first flue 61, then sequentially passes through the absorption tower 1 and the outlet 12 of the absorption tower 1, and then passes through the clean flue 2 to the chimney 4.
4. When the booster fan 7 is started normally, the second shutter door 32 in the booster fan bypass flue 8 is allowed to be closed.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
