Description
Technical field
The invention belongs to panalarm technical field, be specifically related to a kind of nitric acid leakage warning device.
Background technology
Nitric acid is a kind of strong oxidizing property, corrosive strong acid.Nitric acid is soluble in water, its solution water white transparency under normal temperature.Its variable concentrations properties of Aqueous Solution is different, and commercially available red fuming nitric acid (RFNA) is constant boiling solution, and massfraction is that 69.2%(is about 16mol/L); Massfraction enough large (commercial concentration is up to more than 98%), be called fuming nitric aicd.Nitric acid is easily shown in that light decomposes, and should keep in Dark Place in brown bottle in shady place, forbids to contact with reductive agent.Nitric acid is industrially main to be produced, in order to manufacture chemical fertilizer, explosive, nitrate etc. with ammonia oxidation; In organic chemistry, the mixed liquor of red fuming nitric acid (RFNA) and the concentrated sulphuric acid is important nitrating agent.
In industrial processes, nitric acid himself possesses stronger usability as the maximum strong acid of use; But, once leaking appears in nitric acid, then can cause the artificial injures and deaths of large area.
Summary of the invention
For above-mentioned weak point of the prior art, the object of the invention is to aim to provide a kind of can and alarm, Timeliness coverage, in time process and can to the ongoing nitric acid leakage warning device of part nitric acid.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of nitric acid leakage warning device, comprises container, contact plate, power supply, audible-visual annunciator, sprinkler head motorized valve, power switch, elastomeric platform; Described container bottom arranges elastomeric platform, described container side contacts with contact plate, audible-visual annunciator and sprinkler head motorized valve are set below described power supply respectively, described power switch to be arranged at immediately below contact plate and to be connected with power supply, described internal tank is provided with neutralization warning material, and described warning material is white lime.
Specifically, when nitric acid occurs to leak, the acid mist produced can enter into container and react with white lime, generate calcium salt and water, chemical equation: Ca (OH) 2+2HNO3=Ca (NO3) 2+2H2O, the quality of Ca (NO3) 2 is greater than Ca (OH), the change of weight makes elastomeric platform drive container and contact plate toward declining, when contact plate presses power switch time, power supply is connected, audible-visual annunciator works, the sprinkler head motorized valve of sour room spray equipment is opened simultaneously, spray equipment starts water spray, nitric acid is revealed in dilution, part nitric acid is different simultaneously neutralizes by white lime, greatly reduce concentration of nitric acid comparatively speaking, improve security.
Further preferably, described container coordinates with elastomeric platform contact, and described elastomeric platform inside arranges some flexible adjustment keys, and described flexible adjustment key is Compress Spring.Such design can improve container stability, improves detection efficiency and accuracy simultaneously.
Further preferably, clearance fit between described power switch and contact plate, described power switch is provided with gravity pick-up unit, is spaced apart 10 ~ 100mm between described power switch and contact plate.Such design can regulate interval between power switch and contact plate according to actual conditions thus more efficiently and accurately carry out nitric acid detection.
Further preferably, described container has antiseptic property.Such design can improve container serviceable life, extension device stability.
The present invention has the following advantages relative to prior art:
In use, (1) reduces can not the economic loss brought to company of leakage acid phenomenon of Timeliness coverage in the present invention; (2) worker's personal safety can be ensured to greatest extent when nitric acid leakage accident occurs, reduce Occupational Disease Hazards.In sum, the present invention has stronger adaptability, is convenient to extensively popularize use.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention, simple introduction is done below by the accompanying drawing used required in embodiment, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not making under creative work prerequisite, and the every other embodiment obtained, all belongs to scope.
A nitric acid leakage warning device as shown in Figure 1, comprises container 1, contact plate 2, power supply 3, audible-visual annunciator 4, sprinkler head motorized valve 5, power switch 6, elastomeric platform 8; Bottom described container 1, elastomeric platform 8 is set, described container 1 side contacts with contact plate 2, audible-visual annunciator 4 and sprinkler head motorized valve 5 are set below described power supply 3 respectively, described power switch 6 to be arranged at immediately below contact plate 2 and to be connected with power supply 3, described container 1 inside is provided with neutralization warning material 7, and described warning material 7 is white lime.
Specifically, when nitric acid occurs to leak, the acid mist produced can enter into container 1 and react with white lime, generate calcium salt and water, chemical equation: Ca (OH) 2+2HNO3=Ca (NO3) 2+2H2O, the quality of Ca (NO3) 2 is greater than Ca (OH), the change of weight makes elastomeric platform 8 drive container 1 and contact plate 2 toward declining, when contact plate 2 presses power switch 6 time, power supply 3 is connected, audible-visual annunciator 4 works, the sprinkler head motorized valve 5 of sour room spray equipment is opened simultaneously, spray equipment starts water spray, nitric acid is revealed in dilution, part nitric acid is different simultaneously neutralizes by white lime, greatly reduce concentration of nitric acid comparatively speaking, improve security.
