Due to the adoption of the structure, when the water level of the diffusing tower rises, the rising signal of the floating ball switch is fed back and closed, and the control cabinet sends a signal to the electromagnetic valve to prompt the electromagnetic valve to open for draining; when the water level of the diffusing tower is reduced, the floating ball switch is reduced, the signal feedback is disconnected, the control cabinet sends a signal to prompt the electromagnetic valve, the electromagnetic valve is closed, and the water drainage is stopped.
Furthermore, the alarm device also comprises an alarm device, and the float switch sends a signal to the alarm device.
By adopting the structure, the water level of the diffusing tower changes, so that the float switch is fed back to be opened or closed, a signal is transmitted to the alarm device, and manual drainage or closed drainage is performed.
Further, the liquid level detection device is 0-3 meters away from the lower part of the tower body in the vertical direction.
Due to the adoption of the structure, the liquid level detection device is convenient to manually inject water and maintain.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. the utility model discloses a set up the position change that liquid level detection device can detect the internal water level of tower, through to water level detection, when detecting the water level too high, the staff discharges the operation to the water in the tower body, can prevent that the internal water level of tower is higher than BOG discharge port or EAG discharge port, leads to freezing the problem that causes the jam in it.
2. The utility model discloses set up the water filling port on liquid level detection device, can detect and verify whether float switch is normal when through annotating water to the liquid level box, whether have signal feedback, it is more convenient and more water economy resource to operate.
3. The utility model discloses a set up alarm device and or switch board, realize semi-automatization or full automatization's water level control, very big reduction the cost of labor.
