The gas alarm 6 is a fixed gas alarm and is arranged on the outer side of the upper part of the cylinder 4 and is 3.9 meters away from the ground. Once the gas is discharged from the water discharge pipe 3 of the desulfurizing tower, the gas rises along the wall of the cylinder 4, and the gas alarm 6 can detect and send out alarm whistle to prompt an operator to close the water discharge valve 2 of the desulfurizing tower and the surrounding pedestrians in time.
Hand holes 8 with the diameter of 150mm are arranged at the lower parts of the cylinder walls of the water inlet side and the water outlet side of the cylinder body 4, so that sundries in the cylinder body 4 can be cleaned conveniently.
Every two hours the worker goes to manually open desulfurizing tower drain valve 2 and drains, and the comdenstion water can get into barrel 4 bottom breakwater 11 along desulfurizing tower drain pipe 3 and intake the side, and rethread breakwater 11 gets into out the water side, goes out water side liquid level and risees, and when the liquid level exceeded barrel drain pipe 7's level in barrel 4, the comdenstion water passed through barrel drain pipe 7 and gets into sump pit 9.
In the drainage process, workers pay close attention to the condition of a drainage port of a drainage pipe 3 of the desulfurizing tower through an observation hole 5, and when bubbles in water are observed to increase, the workers immediately close a drainage valve 2 of the desulfurizing tower. Because the water inlet of the cylinder drain pipe 7 faces downwards, water sealing is carried out below the liquid level, the discharged coal gas can only rise along the cylinder 4, if the coal gas amount is large, the coal gas alarm 6 arranged on the outer side of the top of the cylinder 4 gives an alarm, workers confirm that the desulfurization tower drain valve 2 is closed and the outlet of the desulfurization tower drain pipe 3 does not generate bubbles and then evacuate, and surrounding pedestrians walk around. And because the cylinder 4 is higher, the periphery is spacious, easy coal gas diffusion, after the coal gas diffuses naturally, the alarm sound of the coal gas alarm 6 stops. The invention improves the safety protection of workers on the water drainage of the desulfurizing tower and eliminates the potential safety hazard of coal gas poisoning.
