Ease, if increasing unnecessary construction cost if too small and wasting great lot of water resources, if ammonia detector 9 is stored up with liquefied ammonia
Distance is excessive between tank 13, then can not accurately detect NH_3 leakage at the first time, system interlink starts overlong time, place of meeting an urgent need
Effect is put to have a greatly reduced quality, if if too small 9 effective reconnaissance range of ammonia detector it is too small, can not detect in zone of reasonableness
NH_3 leakage, if the excessive or stabilization time that ammonia warning concentration is set is long, cannot start emergency disposal in time, if report
Alert concentration setting too low or stabilization time is too short, then system can electrically drift about because of equipment, cause continually to malfunction.By a large amount of
Actual test, we have shown that gas detector is located at 1.1m -1.6m of the top of liquid ammonia storage tank 13, the spacing between nozzle
For 0.4m -0.7m, spacing is 0.7m -1.0m between every layer of water spray feed pipe, and ammonia reaches the stabilization time of warning concentration
More than 1.0 seconds, on this condition, liquid ammonia storage tank leakage ammonia can comprehensively, rapidly, be efficiently disposed, to ensure related work
Personnel safety, which is withdrawn, provides feasible operation scheme.
The above is only the preferred embodiment of the present invention, is not intended to limit the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is some improvement and
Modification, these improvements and modifications also should be regarded as protection scope of the present invention.
