【摘要】：近年來,霧霾天氣日趨常態(tài)化,PM2.5嚴重威脅人們的日常生活,據(jù)有關(guān)資料統(tǒng)計,城市大氣環(huán)境污染60%來自機動車輛的尾氣排放。隨著車用天然氣在國家能源戰(zhàn)略中的地位日益凸顯,全國各地加氣站和天然氣汽車數(shù)量增長都十分迅速,據(jù)不完全統(tǒng)計,目前我國加氣站數(shù)量達4300座左右,而天然氣汽車保有量約為300萬輛。然而隨著我國天然氣汽車保有量和天然氣加氣站數(shù)量的不斷攀升,天然氣汽車和加氣站的安全事故時有發(fā)生。國內(nèi)外對天然氣加氣站的安全評價研究日趨成熟,但是大部分是針對CNG類型的加氣站進行安全評價研究,而對于LNG或L-CNG類型加氣站的安全評價研究非常少,因此,選擇對這一類型加氣站項目進行全面分析和評價研究,具有重要的現(xiàn)實意義。論文以泉州市東海L-CNG加氣站項目為研究案例,首先通過對國內(nèi)外加氣站安全評價文獻的研究回顧,綜合運用了文獻研究法、案例研究法等研究方法,采用安全檢查表法、危險度評價法、蒸汽云爆炸法等安全評價方法分析整個加氣站系統(tǒng)并劃分評價單元,隨后針對每個評價單元可能存在的安全風(fēng)險、有害因素的種類和程度進行綜合定性和定量分析、評價,進而提出針對L-CNG類型加氣站項目的安全運行對策與建議。運用安全檢查表法進行評價時,論文采用國家標準《燃氣系統(tǒng)運行安全評價標準》(GB/T50811-2012)中的檢查表對評價單元進行評分,得出評價對象的總得分,最后根據(jù)得分情況依據(jù)《評價結(jié)論對照表》做出評價結(jié)論和建議,這具有一定創(chuàng)新性和先進性。
[Abstract]:In recent years, haze weather is becoming more and more regular, PM2.5 is a serious threat to people's daily life, according to relevant data statistics. Urban air pollution 60% comes from the exhaust emissions of motor vehicles. With the increasing status of natural gas in the national energy strategy, the number of gas stations and natural gas vehicles all over the country is growing rapidly. According to incomplete statistics, the number of gas filling stations in China is about 4300 at present. However, with the increase of the number of natural gas vehicles and natural gas filling stations in China, the number of natural gas vehicles is increasing. Safety accidents of natural gas vehicles and filling stations occur from time to time. The research on safety evaluation of natural gas filling stations at home and abroad is becoming more and more mature, but most of the safety evaluation research is aimed at CNG filling stations. But for the LNG or L-CNG type filling station safety evaluation research is very few, therefore, choose to this type of filling station project comprehensive analysis and evaluation research. This paper takes the project of L-CNG gas filling station in Quanzhou City as a case study. Firstly, through the review of domestic and foreign gas station safety evaluation literature, a comprehensive use of literature research method. Case study and other research methods, using safety inspection table method, risk assessment method, steam cloud explosion method and other safety evaluation methods to analyze the whole gas station system and divided into evaluation units. Then according to each evaluation unit may have the safety risk, the harmful factor kind and the degree carries on the synthesis qualitative and the quantitative analysis, the appraisal. And then put forward the safe operation countermeasures and suggestions for L-CNG type filling station project. When using the safety check table method to evaluate. In this paper, the evaluation unit is graded with the check table in the National Standard of Safety Evaluation of Gas system (GB / T50811-2012), and the total score of the evaluation object is obtained. Finally, the evaluation conclusions and suggestions are made according to the comparison table of evaluation conclusions according to the score situation, which is innovative and advanced.
