      石化儲罐區泄漏監測與消防設備聯動要求
      ①監測系統的主導思想 。油罐區火災監控系統是以火災為監測對象,根據防災要求和特點而設計、構成和工作的,是一種及時發現和通報火情,并采取有效措施控制和撲滅火災而設置在油罐對象中的自動消防設施,是將油罐火消滅在萌芽狀態,最大限度地減少火災的有力工具。隨著社會對消防和救災搶險工作提出越來越高的要求,消防技術設施和消防技術手段之一,也越來越顯示出它的重要性。 
      ①The main idea of monitoring system. Fire monitoring system in oil tank area is designed, constructed and operated according to the requirements and characteristics of fire prevention. It is an automatic fire control facility that can detect and report fire situation in time, take effective measures to control and extinguish fire and set it in the object of oil tank. It is to extinguish oil tank fire in the budding state to the maximum extent possible. A powerful tool for reducing fires. With the society's increasing demands on fire fighting and disaster relief and rescue work, fire fighting technology facilities and one of the means of fire fighting technology are also increasingly showing its importance.
      ②監測系統的監測參數。
      (1)機械――罐體、閥門、管件以及支撐建筑物的強度;
      (2)工藝――儲罐內部的壓力、溫度、液體、成分、以及與儲罐內物理化學狀態密切相關的流量等;
      (3) 氣象――風速、風向、氣溫、氣壓、溫度;
      (4)火險――液化石油氣包括許多易燃易爆氣體,它是由石油經過石油化工廠過程中得到的,主要成分有乙烷、丙烷、丁烷、丙烯丁烯等等,火險分類為甲類。 

      ②jiān cè xì tǒng de jiān cè cān shù 。
      (1)jī xiè ――guàn tǐ 、fá mén 、guǎn jiàn yǐ jí zhī chēng jiàn zhù wù de qiáng dù ; 
      (2)gōng yì ――chǔ guàn nèi bù de yā lì 、wēn dù 、yè tǐ 、chéng fèn 、yǐ jí yǔ chǔ guàn nèi wù lǐ huà xué zhuàng tài mì qiē xiàng guān de liú liàng děng ;
      (3) qì xiàng ――fēng sù 、fēng xiàng 、qì wēn 、qì yā 、wēn dù ;
      (4)huǒ xiǎn ――yè huà shí yóu qì bāo kuò xǔ duō yì rán yì bào qì tǐ ,tā shì yóu shí yóu jīng guò shí yóu huà gōng chǎng guò chéng zhōng dé dào de ,zhǔ yào chéng fèn yǒu yǐ wán 、bǐng wán 、dīng wán 、bǐng xī dīng xī děng děng ,huǒ xiǎn fèn lèi wéi jiǎ lèi 。

      ③泄漏監測要求。根據石化儲罐區特殊的火災危險性和可燃氣體及易燃液體泄漏監測實際需要,其消防安全監測參數主要是可燃氣體濃度、成分、溫度、液位或壓力等工藝參數。此外,石化儲罐區的火災監測參數應充分考慮罐區特點來確定,當儲存油品為原油等重質油品時,因其含碳量較多,燃燒將產生大量的煙氣,火災探測的重點是對煙氣濃度的探測。 
      總體來講,石化儲罐區消防安全監測要求是通過對工藝參數和火災參數的實時監測和數據分析,實現參數異常情況及時報警并預測判斷可能的后果,采取有效的聯動控制方式,啟動消防安全設施及滅火設施。據此,在石化監測環境中工藝參數的監測要求,主要是有效測量各類參數,分析預測石化儲罐區的安全狀態、事故可能性及火災危險性,根據判斷結果采取相應的安全措施;對火災參數的監測要求是在火災初期對煙氣濃度、溫度、光輻射強度等進行有效監測,綜合分析監測數據,及時產生報警信號及聯動控制信號,有效啟動現場滅火設備。 
      ③ Leakage monitoring requirements. According to the special fire danger of petrochemical tank area and the actual need of monitoring the leakage of flammable gas and liquid, the main parameters of fire safety monitoring are the concentration, composition, temperature, liquid level or pressure of flammable gas. In addition, the fire monitoring parameters of petrochemical storage tank area should be determined with full consideration of the characteristics of the tank area. When the storage oil is heavy oil such as crude oil, because of its high carbon content, combustion will produce a large amount of smoke. The focus of fire detection is to detect the smoke concentration.
      Generally speaking, the requirement of fire safety monitoring in petrochemical storage tank area is to timely alarm and predict the possible consequences of abnormal parameters by real-time monitoring and data analysis of process parameters and fire parameters, and to adopt effective linkage control mode to start fire safety facilities and fire extinguishing facilities. Accordingly, the monitoring requirements of process parameters in petrochemical monitoring environment are mainly effective measurement of various parameters, analysis and prediction of safety status, accident possibility and fire risk in petrochemical storage tank area, and corresponding safety measures are taken according to the judgement results; the monitoring requirements of fire parameters are smoke concentration and temperature in the early stage of fire. Effective monitoring of degree and light radiation intensity, comprehensive analysis of monitoring data, timely generation of alarm signals and linkage control signals, effective start-up of field fire extinguishing equipment.
      ④消防設備聯動控制要求。石化儲罐區的消防設備主要包括火災警報裝置、滅火設備及安全操作設備?;馂木瘓笱b置是為了在安全參數出現異?;蚧馂陌l生時產生及時報警,主要設備有警鈴、水力警鈴、事故廣播等。滅火設備是為了在火災初期有效的控制火勢,及時撲滅初起火災,主要設備有消防炮、泡沫泵、自動噴淋泵等。安全操作設備是為了在安全參數出現異常時對物料管線及各種控制閥門進行控制和操作,如壓力閥等。
