Description
技术领域：Technical field:
本实用新型涉及一种可根据贮氨站内氨气体浓度的变化，自动开启或关闭的水喷淋装置，具体涉及一种对氨气这种有毒有害气体泄露过程中实现液相吸收功能的安全装置。The utility model relates to a water spray device which can be automatically opened or closed according to the change of the concentration of ammonia gas in an ammonia storage station, in particular to a safety device which realizes the liquid-phase absorption function in the process of leakage of toxic and harmful gas such as ammonia gas .
背景技术：Background technique:
全国涉氨企业众多，截至There are many ammonia-related enterprises in the country, as of 20142014 年底，全国共排查涉氨企业At the end of the year, a total of ammonia-related enterprises were investigated across the country 2283522835 家。近些年，氨泄漏扩散导致较大影响的公共安全事件频频发生，液氨泄漏后会迅速扩散，并汽化为毒性氨气，严重污染空气，与空气形成爆炸性混合物，遇明火、高热能引起燃烧爆炸，爆炸后形成大面积的危险区域，不仅对周围的人员和环境造成严重的危害，而且易引发更大规模火灾和爆炸等事故。氨气易溶于水，常温常压下，Home. In recent years, the leakage and diffusion of ammonia have caused frequent occurrence of public safety incidents with great impact. After the leakage of liquid ammonia, it will spread rapidly and vaporize into toxic ammonia gas, which seriously pollutes the air and forms an explosive mixture with air, which can cause combustion when exposed to open flames and high heat. After the explosion, a large area of dangerous area is formed, which not only causes serious harm to the surrounding personnel and the environment, but also easily causes accidents such as larger-scale fires and explosions. Ammonia gas is easily soluble in water, under normal temperature and pressure, 11 体积水可以溶解volume water can dissolve 560560 体积氨气，国家《冷库设计规范》Volumetric ammonia, national "Code for Design of Cold Storage" GB50072-2010GB50072-2010 中也因为氨的易溶水性，对有关安全装置进行规定，“压缩机房贮氨器上方宜设置水喷淋系统和选用开式喷嘴”。目前，根据混合物中各组分在某一种溶剂中溶解度不同，化工产业中普遍利用互溶原理吸收操作回收气体中的有害成分，净化气体，达到降低有毒有害气体危险性的目的。喷淋系统作为应急救援装置，液氨泄漏事故发生时，其可以迅速降低贮氨站内空气中氨气浓度、减缓氨气扩散速度，降低事故严重程度。Also because of the water-soluble nature of ammonia, the relevant safety devices are stipulated, "It is advisable to install a water spray system and open nozzles above the ammonia storage in the compressor room." At present, according to the different solubility of each component in a mixture in a certain solvent, the principle of mutual solubility is generally used in the chemical industry to absorb and recover harmful components in the gas, purify the gas, and achieve the purpose of reducing the risk of toxic and harmful gases. As an emergency rescue device, the sprinkler system can quickly reduce the concentration of ammonia gas in the air in the ammonia storage station, slow down the diffusion speed of ammonia gas, and reduce the severity of the accident when a liquid ammonia leakage accident occurs.
目前，喷淋系统在国内大多用于危险场所灭火用途，很少使用在氨气等有毒有害气体泄露事故应急处置方面。当涉氨企业发生氨泄漏事故时，多数情况下采取关闭贮氨阀门，切断危险源，疏散撤离人员，手动开启消防喷淋水扑救，有时甚至需要消防救护人员配合才能处理。而这样的应急处理方式具有诸多弊端：At present, sprinkler systems are mostly used for fire extinguishing in dangerous places in China, and are rarely used in emergency response to leakage of toxic and harmful gases such as ammonia. When an ammonia leakage accident occurs in an ammonia-related enterprise, in most cases, the ammonia storage valve is closed, the source of danger is cut off, the evacuated personnel are evacuated, and the fire sprinkler water is manually turned on to fight the rescue. Sometimes even the cooperation of fire rescue personnel is required to deal with it. However, such an emergency treatment method has many disadvantages:
（( 11 ）泄漏氨扩散范围广、速度快，现场人工使用消防水扑救可能造成人员中毒伤害，增加损失和救援难度。) leaked ammonia has a wide range and fast speed, and the manual use of firefighting water on site may cause poisoning and injury to personnel, increasing losses and difficulty in rescue.
（( 22 ）人员开启消防水消耗反应时间，拖延救援进程，会造成其他严重的后果。) personnel turn on the fire water to consume reaction time, delay the rescue process, and cause other serious consequences.
（( 33 ）现场人工处置有时无法接近事故源，难以有效全面的喷洒泄露区域，可能造成局部扩散程度加大。) On-site manual disposal sometimes cannot get close to the source of the accident, and it is difficult to spray the leakage area effectively and comprehensively, which may cause increased local diffusion.
