The specific embodiment
Below, embodiments of the present invention are described with reference to the accompanying drawings.
At the fume automatic ventilated spraying system that is used for the absorption tower of the present invention, described fume automatic ventilated spraying system comprises: spray subsystem and RACS.
As shown in Figure 1, the spray subsystem has: the accident cooling water tank 5 that is used for retaining; The female pipe 3 of the spray that one end is connected with accident cooling water tank 5, the female pipe 3 of this spray has at least one automatic valve 4a; With the spray equipment 2 that the other end of the female pipe 3 of spray links to each other, this spray equipment 2 is arranged in the preceding flue 1 of absorption tower inlet, and a plurality of nozzle 2a are arranged.In actual applications,, more closely sealing safer in order when closing, to realize, the female pipe 3 of spray can also have another automatic valve 4b.And described RACS and automatic valve 4a, 4b are equipped with standby electricity, as battery, therefore, can guarantee that automatic valve 4a, 4b also can open fast under the situation of power plant's dead electricity.
RACS comprises: the sensing device that detects the flue gas state in the preceding flue 1 of absorption tower inlet; With the signal that links to each other with sensing device, can send according to sensing device to spraying the automatic valve 4a on female pipe 3, the control device that 4b controls.The state of the flue gas in the flue 1 of sensing device detection before the inlet of absorption tower, when the flue gas state is undesirable, for example when flue-gas temperature is higher than predetermined value, sensing device sends signal to control device, thereby control device sends instruction according to this signal to the spray subsystem, opens automatic valve 4a, 4b and sprays.At this moment, accident cooling water tank 5 is arranged on the top of flue, and spray system adopts the gravity flow mode.And when the liquid level of accident cooling water tank 5 was reduced to predetermined altitude, it can automatic water supplement.
In addition, according to as mentioned above, above-mentioned sensing device can be temperature sensor as required, when the temperature of flue gas surpasses predetermined value, just sends signal to control device immediately.
