Description
Technical field
The invention belongs to depositing and the use field of ammonia tank, a kind of ammonia tank is lowered the temperature automatically and is revealed alarm integrated control system specifically.
Background technique
Ammonia tank is used for the ammonia of storing liquid, and liquefied ammonia is liquefied under suitable pressure condition by ammonia and forms.Ammonia is a kind of colourless toxic gas with pungent odor, and it can attack skin, mucous membrane and eyes, can cause serious cough, bronchospasm, acute pulmonary edema, even can cause blind and death by suffocation.In addition, ammonia mixes with air or oxygen can form explosive mixture, very likely blasts when ammonia tank is heated.
Ammonia tank belongs to great inflammable and explosive dangerous matter sources, and it is generally deposited in the open or under the semiclosed environment, no good adiabatic protective measures, and when summer high temperature weather, the situation of safe storage temperature can appear surpassing in ammonia tank.Simultaneously, owing to be subjected to the influence of thermal expansion and high-temperature evaporation, the internal pressure of ammonia tank can increase, thereby can strengthen the leakage possibility of ammonia tank and pipeline valve, has bigger potential safety hazard.In order to ensure safety in production, need the strict leakage of avoiding ammonia tank, also must lower the temperature to tank body during the broiling summer simultaneously.
For the cooling of ammonia tank, the modes that adopt artificial spray cooling when hot in summer, also often used water pump to extract tap water and constantly ammonia tank are carried out spraying cooling more at present.The shortcoming of existing cooling measure is: 1) for artificial water spray, can expend too much labour force, and temperature-fall period is subjected to the influence of people's subjective factor, the very difficult cool effect that guarantees; 2) for the water pump spray, the water pump continuous running can cause unnecessary waste to power and water, and simultaneously, tank body continues contact water can aggravate its corrosion, influences the working life of ammonia tank.
Leakage for ammonia tank, the ammonia leak detector generally can be installed in the scene of depositing at ammonia tank, the ammonia leak detector is sent the alarm signal of different stage according to its detected ammonia leakage degree, and the staff receives the report for police service to be on the scene behind the signal and handles.For the leakage of ammonia tank, only can send alarm signal at present, the on-the-spot measure that does not have corresponding automatic harm reduction, the ammonia of leakage can fly away in air, if run into hot environment again, very easily causes danger, and seriously jeopardizes field personnel's safety.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of ammonia tank and lowers the temperature automatically and reveal alarm integrated processing system, this system can deposit on-the-spot situation according to ammonia tank and take automatically to lower the temperature and reduce the measure of revealing harm, and whole system is simple in structure, control is convenient, can labor savings can reduce the wasting of resources again.
