Abstract
The invention discloses an alarming and explosion protection system of an ammonia refrigerating station. The alarming and explosion protection system is composed of a controller, a gas concentration alarming device, an electromagnetic valve, an water atomization device and a water filtration and exhaust device; the gas concentration alarming device gives out a sound-light alarm when the leakage is caused and the ammonia concentration of indoor air exceeds a standard in the ammonia refrigerating station; meanwhile, the controller starts the electromagnetic valve, the water atomization device and the water filtration and exhaust device, and an ammonia source is cut off after the electromagnetic valve is started; the space in the ammonia refrigerating station is filled with water vapor after the water atomization device is started, therefore, on the one hand, the air humidity can be improved by the water vapor, on the other hand, the water vapor is reacted with ammonia gas in the air to create ammonia vapor to reduce the concentration of the ammonia gas in the air, and further the danger of explosion can be reduced; in addition, after the water filtration and exhaust device is started, the ammonia-contained air in the ammonia refrigerating station is discharged outdoors after being absorbed and filtrated by water, therefore, the ammonia concentration in the ammonia refrigerating station can be reduced, and the pollution level of air environment outside the ammonia refrigerating station caused by the ammonia gas can be alleviated, moreover more time can be won for the disposal of an leakage accident to reach the aims of alarming and explosion protection.
Description
Technical field
The invention belongs to ammonia refrigerating installation warning explosion-proof technology field, particularly relate to a kind of ammonia refrigeration machine room and report to the police and explosion protection system.
Background technology
Ammonia (English: Ammonia), molecular formula is NH3, and molecular weight is 17.Ammonia is a kind of colourless gas, there is strong impulse smell, belong to poisonous, pernicious gas, lta during gaseous state, very easily water-soluble, 1 volume water dissolvable, 700 times of volume ammonia at normal temperatures and pressures, the alkaline solution of the water-soluble rear formation ammonium hydroxide of ammonia, ammonia belongs to imflammable gas, and explosion limit is 15 .7 % ~ 27 %, form explosive mixture with air mixing energy, chance naked light, high heat energy cause combustion explosion.Ammonia is as nonpolluting cold-producing medium, and be zero to ozone depletion latent energy value (ODP value), global warming potential (GWP value) is zero, and have cheap, the advantages such as efficiency is high, good heat-transfer are the cold-producing mediums of the most desirable, most environmental protection in the world today.Because ammonia belongs to poisonous and harmful, inflammable and explosive medium, therefore, the key issue of ammonia refrigeration system is exactly safety problem.Specify in GB50072-2010 " Code for design of coldstorages " 7.2.1 article: " ammonia refrigeration machine room should arrange ammonia gas concentration alarm device; when the concentration of Ammonia in Air gas reaches 100ppm or 150ppm; automatically should send alarm signal, and automatically should open the accident exhaust blower of refrigerating plant room ".The technology of current ammonia gas concentration alarm device can only tackle less ammonia leakage accident: when the concentration of Ammonia in Air gas is up to standard, automatically can send alarm signal, and automatically opens the accident exhaust blower of refrigerating plant room; If when leakage rate is larger, the ammonia level concentration of the outer neighbouring surrounding air of machine room just may be made also to exceed standard, not only can cause the outer neighbouring ambient air contamination of machine room, also can weaken the effect of exhaust blower, make the danger of blasting constantly increase.
Summary of the invention
object of the present invention:the present invention is exactly for the problems referred to above, provides a kind of ammonia refrigeration machine room to report to the police and explosion protection system.
the present invention is achieved in thatammonia refrigeration machine room is reported to the police and explosion protection system, is made up of controller, gas concentration warning device, magnetic valve, water atomization plant, water filtration exhaust apparatus.When ammonia refrigeration machine room occurs to leak and room air ammonia density exceeds standard, namely gas concentration warning device sends sound and light alarm; Start magnetic valve, water atomization plant and water filtration exhaust apparatus with Time Controller, magnetic valve cuts off ammonia sources after starting; Water atomization plant makes space in machine room all be full of water smoke vapour after starting, water smoke vapour is increase air humidity on the one hand, ammonia gas react on the other hand in water smoke vapour and air generates ammoniacal liquor vapour, reduces the concentration of Ammonia in Air gas, thus reduces the danger of blasting; After water filtration exhaust apparatus starts, machine room is included ammonia air and be discharged to outdoor again after water absorbing and filtering, not only reduce ammonia concentration in machine room, also mitigate the pollution level of ammonia to machine room outer air environment, gaining time for disposing leakage accident, reaching and reporting to the police and explosion-proof object.
