Embodiment
The present invention is described in further detail below by specific embodiment and with reference to accompanying drawing.
As shown in figure 1, a kind of hydrolysis of urea spraying system of fire fighting of the embodiment of the present invention, if including spray water supply installation,
Dry hydrolysis of urea sled block spray equipment and controller.The water side and each hydrolysis of urea sled block spray for spraying water supply installation are filled
The water inlet end connection put.
Each hydrolysis of urea sled block spray equipment includes ring-type spray piping 1, leakage ammonia detector 2 and the first pneumatic control
Valve 3, the water inlet end of ring-type spray piping 1 sets first pneumatic control valve 3, leakage ammonia detector 2 and the first pneumatic control
Valve 3 is connected with spraying the water side of water supply installation, set on interlocking switch by interlocking switch electric interlock, leakage ammonia detector 2
Warning device is put, leakage ammonia detector 2, the first pneumatic control valve 3 and warning device are electrically connected with controller.First is pneumatic
Control valve 3 is pneumatic ball valve.Controller can realize the monitoring to leaking ammonia detector 2, when leakage ammonia detector 2 reaches alarming value
When, leakage value can be shown on the controller, meanwhile, warning device meeting alarm needs to carry out ammonia dilution.Each urea water
Leakage ammonia detector 2 on solution sled block is detected to the ammonia leakage in the region respectively, is prized by multiple hydrolysis of urea on block
Leakage ammonia detector 2 can realize in hydrolysis of urea tank whole region ammonia leakage detection, it is to avoid missing inspection test leakage and occur
It is dangerous.
Such as when prizing block and ammonia leakage occurs for annex, pass through opening for the first pneumatic control valve of controller remote control 3
Open and close, it is possible to realize the remote control sprayed to hydrolysis zone, ammonia leakage is effectively diluted, it is not necessary to have production
