an ammonia gas detector is installed on one side of the ammonia equipment, the ammonia gas detector is connected to a microcontroller, and the electromagnetic valve is also connected to the microcontroller.
The ammonia plant is an ammonia storage tank or a plant using liquid ammonia, for example, a plant using ammonia gas such as an ammonia compression refrigerator.
The utility model discloses the during operation, the ammonia detector detects the air around the ammonia equipment, and will detect on data transmission microcontroller, the setting value of the ammonia gas concentration of storage in the microcontroller, when data detected reaches or surpasses this setting value, then judge that the ammonia equipment takes place to leak, microcontroller sends the opening command to the solenoid valve, the solenoid valve opens, fire water is spout in the atomizer, absorb the ammonia of leaking, form the aqueous ammonia, the aqueous ammonia drops to carry out centralized processing in the waste water collection pond downwards.
Utilize the utility model discloses can effectively absorb the ammonia that spills fast, avoid the diffusion of ammonia, prevent the injury to environment and personnel on every side to strive for the time for the maintenance of equipment.
Further, in order to reduce the usage amount of the atomizing nozzle and the water consumption, the atomizing nozzle is a spiral nozzle, and the spraying angle of the spiral nozzle is 120-150 degrees. The spiral nozzle sprays less liquid drops, so that the contact area of the spiral nozzle and ammonia gas can be effectively increased, the ammonia gas can be quickly absorbed, and the water consumption is reduced.
Further, to avoid the waste water to cause corrosion to the equipment on the support, this waste water collecting tank is arranged around this support, and the mounting surface of this support upwards exceeds the up end of the pool wall of this waste water collecting tank. The arrangement of the waste water collecting tank around the support can ensure that waste water can smoothly enter the waste water collecting tank.
Further, in order to reduce the inorganization discharge amount of the waste water, the outer edge of the waste water collecting tank outwards exceeds the coverage area of the water mist sprayed by the atomizing nozzles. This design can make atomizing nozzle spun water smoke directly drop to the waste water collecting tank in, avoids the outside diffusion to the waste water collecting tank.
Further, in order to improve the corrosion resistance of the support, the support is of a concrete structure.
