Description
Technical field:
This utility model relates to a kind of to be specifically related to realize during a kind of toxic and harmful this to ammonia is revealed the safety device of liquid phase scrubbing function according to the change of ammonia gas concentration in storage ammonia station, the water spray system automatically turning on or closing.
Background technology:
Whole nation She An enterprise is numerous, by
2014
In the end of the year, She An enterprise is investigated in the whole nation altogether
22835
Family.In recent years; NH_3 leakage diffusion causes the occurred events of public safety of considerable influence again and again to occur; can spread rapidly after A leak of liquefied ammonia; and it is vaporizated into toxicity ammonia, severe contamination air, form explosive mixture with air; meet naked light, high heat energy causes combustion explosion; forming large-area deathtrap after blast, not only personnel and environment to surrounding cause serious harm, and easily cause the accident such as larger-scale fire and blast.Ammonia is soluble in water, under normal temperature and pressure,
1
Volume of water can dissolve
560
Volume ammonia, country's " Code for design of coldstorages "
GB50072-2010
In also because the easy solubization of ammonia, relevant safety device is specified, " water sprinkler system is preferably set above compressor room ammonia storage tank and selects open-type nozzle ".At present, according to component each in mixture different solubility in a certain solvent, chemical industry generally utilizes the harmful components in principle absorption operation gas recovery of dissolving each other, purifies gas, reduce the purpose that toxic and harmful is dangerous.Spray system is as emergency rescue device, and when A leak of liquefied ammonia accident occurs, it can reduce rapidly Ammonia in Air gas concentration in storage ammonia station, slow down ammonia diffusion velocity, reduces severity of injuries.
At present, spray system is mostly used for hazardous area fire extinguishing purposes at home, is rarely employed in terms of the toxic and harmfuls such as ammonia reveal accident emergency disposal.When She An enterprise occurs NH_3 leakage accident, in most cases taking to close storage ammonia valve door, cut off dangerous matter sources, evacuation egress personnel, manually opened fire-fighting spraying water is puted out a fire to save life and property, and the most even needing fire-fighting rescue personnel to coordinate could process.And such emergency processing mode has, and all kinds of corrupt practices creep in:
(
1
) leakage ammonia range of scatter is wide, speed fast, on-the-spot artificial use fire water is puted out a fire to save life and property and is likely to result in toxicity damage in personnel, increases loss and rescue difficulty.
(
2
) personnel open fire water consume the response time, delay rescue process, other serious consequences can be caused.
(
3
) on-the-spot artificial disposal sometimes cannot be close to accident source, it is difficult to effectively comprehensively spray leak area, be likely to result in local diffusion degree and strengthen.
Utility model content:
The purpose of this utility model is to provide a kind of liquefied ammonia and reveals the Water spray absorption system pressing down expansion, can be widely applied in the emergent anti-Ore-controlling Role in agricultural, pharmacy, birds production, storage, chemical industry Deng She ammonia enterprise's storage ammonia station.
Above-mentioned purpose is realized by following technical scheme:

Described a kind of liquefied ammonia reveals the automatic water spray-absorption system pressing down expansion, it is characterized in that: described concentration over-standard alarm device sends with acoustical signal, optical signal form, and described concentration over-standard alarm device is connected with described control circuit.
Described a kind of liquefied ammonia reveals the automatic water spray-absorption system pressing down expansion, it is characterized in that: described emergency shutoff device is connected with described water spray system, and is arranged on outside storage ammonia station, by the keying of personnel's Non-follow control water spray system.
The beneficial effects of the utility model:
1.
This utility model diverse location at storage ammonia station installs ammonia monitoring sensor, the concentration mutation of ammonia in the ammonia station of monitoring storage in real time, when occurring liquefied ammonia to reveal, ammonia concentration reaches the threshold value of ammonia monitoring sensor, the control circuit connected controls alarm and sends alarm, prompting operator have liquefied ammonia to reveal, make operator theoretically and the most ready, withdraw in time and evacuate and take measures.Water spray system control circuit controls automatic valve unlatching aqueous medium spray and goes out simultaneously, when leakage accident is controlled, after ammonia concentration declines, spray equipment is automatically switched off, and Water spray shower nozzle is arranged on each position in storage ammonia station, it is to avoid the problem that manual rescue is difficult to spray leak area comprehensively.
This utility model specifically provides a kind of when liquefied ammonia occurs leakage, and by the situation of long-range monitor monitoring leak area ammonia concentration, high degree improves personnel to the prompting of site environment and monitoring, it is simple to being smoothed out of rescue work.
Emergency shutoff device of the present utility model, by the connection with water sprinkler system, can open and close with the work of Non-follow control water sprinkler system, and when automatically controlling section failure, operator can directly control the keying of leak area water sprinkler system.Emergency braking apparatus is all placed on outside storage ammonia station, it is not easy to by leakage accident interference effect, whole during decrease operator and enter the danger of leak area, it is ensured that the safety of operator.
