Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
The utility model provides a kind of power plant smoke evacuation system, this power plant smoke evacuation system comprises the first boiler controller system 1, chimney 2 and cooling tower 3, first row smoke pipeline 5 is connected with between first boiler controller system 1 and chimney 2, be connected with second row smoke pipeline 6 between first boiler controller system 1 and cooling tower 3, described power plant smoke evacuation system also comprises the first control device 7 controlling first row smoke pipeline 5 break-make and the second control device 8 controlling described second row smoke pipeline 6 break-make.
This power plant smoke evacuation system, flue gas is drained into cooling tower 3 by the first boiler controller system 1 under normal circumstances, namely second row smoke pipeline 6 is controlled by second control device 8 open-minded, and control first row smoke pipeline 5 by first control device 7 and close, be disposed to cooling tower 3 with the flue gas making the first boiler controller system 1 discharge by second row smoke pipeline 6, be beneficial to decreasing pollution; But, when cooling tower 3 breaks down or be in the down states such as maintenance, then can control first row smoke pipeline 5 and open, and second row smoke pipeline 6 is closed, and makes the fume emission of the first boiler controller system 1 put chimney 2, can ensure the normal operation of unit.
In addition, the smoke evacuation system that the utility model provides, because the flue gas of the first boiler controller system 1 discharges through cooling tower 3 by the lifting effect of the steam heat of cooling tower 3 under normal circumstances, discharge from chimney 1 without the need to heating again flue gas, only discharge from chimney 1 when cooling tower 3 is out of order or keeps in repair, therefore, flue gas heat-exchange unit (GasGasHeater can be saved, GGH), positive effect is had to saving construction cost, the leakage that removes smoke, reduction maintenance workload etc.
With reference to the accompanying drawings preferred embodiment of the present utility model is specifically described below.
In present embodiment, first control device 7 on first row smoke pipeline 5 and the second control device 8 on second row smoke pipeline 6 are respectively the electric guard board door be arranged in first row smoke pipeline 5 and second row smoke pipeline 6, and flue gas realizes through chimney 2 discharges and flue gas to discharge these two kinds of discharge mode through cooling tower 3 the selection switching by electric guard board door.Electric guard board door is preferably stainless steel.Due to the importance of discharge flue, the control logic of electric guard board door includes unit DCS (DistributedControlSystem, scattered control system) in.
Because the flue gas of boiler controller system discharge is first through wet desulphurization process, after particularly wet electrical dust precipitator is installed in environmental transformation additional, be formed as saturated wet flue gas, wet flue gas can generate a large amount of condensate water in course of conveying, therefore in present embodiment, preferably on second row smoke pipeline 6, be provided with steam trap connection, to discharge the condensate water of generation.Certainly also according to circumstances can need, first row smoke pipeline 5 arrange steam trap connection, or all arranges on both.In addition, after considering dismounting GGH, flue gas is wet flue gas, and there is corrosivity, therefore tackle chimney 2 and carry out preservative treatment, to meet fume emission to instructions for use during chimney 2, also need install draining system additional in chimney 2 simultaneously, to get rid of the condensate water formed in chimney 2, and water can be drained into desulfurization melt pit.And for preventing corrosion, first row smoke pipeline 5 and second row smoke pipeline 6 all can adopt GRP pipe.
This power plant smoke evacuation system also comprises flue support 11, and as shown in Figure 2, second row smoke pipeline 6 is supported on flue support 11.
Second row smoke pipeline 6 is connected to form by multistage pipeline, is provided with expansion joint 61 between each section of described pipeline, to be connected by expansion joint 61.Wherein at least one section described pipeline is tilted to lower setting along flue gas trend, and steam trap connection comprises the drain port of the lowest part being arranged on the described pipeline being tilted to lower setting.
Preferably, described drain port is the drain pipe interface be arranged on expansion joint 61, drain pipe interface is connected with drain pipe 12.As described in Figure 2, drain pipe 12 extends downward desulfurization melt pit 10 along flue support 11, and the condensate water generated in second row smoke pipeline 6 is disposed in desulfurization melt pit 10 along drain pipe 12.
During for preventing winter temperature lower, freezing in drain pipe 12 and stoping the discharge of condensate water, preferably, drain pipe 12 being provided with heater.When temperature is lower, this heater can be opened, drain pipe 12 be heated, and when temperature raises, closes this heater.
First row smoke pipeline 5 also can have setting same or similar with second row smoke pipeline 6, and namely first row smoke pipeline 5 also can be arranged on flue support 11, and steam trap connection on first row smoke pipeline 5 also can be identical with arranging on second row smoke pipeline 6.
In present embodiment, for convenience of smoke evacuation, kink is formed at the port of export being positioned at chimney 2 of first row smoke pipeline 5 and/or the port of export being positioned at cooling tower 3 of second row smoke pipeline 6, but due to the restriction of bending structure, easily there is the phenomenon such as air-flow vortex, streamline disengaging at this in flue gas, brings larger dynamic pressure and drag losses, can have influence on the normal operation of air-introduced machine time serious, for this carries out structure optimization to this kink, to reduce outlet dynamic pressure and resistance.
Specifically as shown in Figure 4, the side of the indent of described kink is formed with diversion division 62, this diversion division 62 can reduce flow velocity loss when flue gas flows through elbow, and eliminate elbow internal vortex, this diversion division 62 is preferably the deflector bending angle of the indent of bending place being formed as chamfering.
In another embodiment, kink forms at least two export departments arranged side by side, specifically as shown in Figure 5, is formed with the first export department 63 and the second export department 64 arranged side by side at kink.By setting up an export department, can discharge area be increased, being beneficial to and reducing outlet dynamic pressure.
