7. A treatment method for an emergency treatment device of a liquid ammonia tank is characterized by comprising the following steps:
s1, when leakage occurs in the liquid ammonia tank (1), when leaked ammonia gas contacts the ammonia gas sensor (505), the ammonia gas sensor (505) gives an alarm, the detection motor (501) is started at the same time, the detection motor (501) is started to drive the rotating shaft (502) to rotate, the rotating shaft (502) rotates to drive the rotating chain (504) to rotate through the rotating gear (503), the ammonia gas sensor (505) is driven to rotate, the ammonia gas sensor (505) moves to the position with the highest ammonia gas concentration, and the leakage point is judged;
s2, after the liquid ammonia tank (1) leaks, the electromagnetic valve (402) can be remotely opened at the moment, so that liquid ammonia in the liquid ammonia tank (1) is led into the ammonia storage pipe (403), the electromagnetic valve (402) at which position is opened can be judged according to the size and the leakage position of the liquid ammonia tank, when the electromagnetic valve (402) is started, the rotating motor (702) is synchronously started, the rotating motor (702) drives the driving bevel gear (704) to rotate through the output shaft (703), the driving bevel gear (704) drives the blades (707) to rotate through the driven bevel gear (705) and the fan shaft (706), so that the leaked ammonia gas is sucked into the exhaust cylinder (709) and is led out through the exhaust pipe (710);
s3, when the rotating motor (702) in the S2 works, the water pump (606) starts to work, the water pump (606) sucks the dilute hydrochloric acid solution in the water storage tank (601) into the water outlet pipe (602) and enters the first branch pipe (603) and the second branch pipe (604), the dilute hydrochloric acid solution can be pressurized and sprayed out through the pressurizing spray head (605), so that a water net is formed, ammonia gas is prevented from leaking, the solution absorbing the ammonia gas flows onto the leakage-proof plate (202) and the filter plate (201) and flows back into the water storage tank (601) through the filter screen of the filter plate (201), and the solution containing the ammonia gas can be prevented from damaging the environment while being repeatedly utilized.
