【摘要】:隨著經(jīng)濟(jì)的高速發(fā)展,全球性的能源危機(jī)和環(huán)境污染問題日益突出,沼氣作為一種清潔無污染且可再生的生物質(zhì)能源,可以有效緩解能源和環(huán)境危機(jī)。近年來在國家政策大力推動(dòng)下,中國的沼氣工程產(chǎn)業(yè)得到了大規(guī)模發(fā)展,但對其所存在的安全問題一直未給予應(yīng)有的重視,留下了重大事故隱患。本文通過查閱文獻(xiàn)和實(shí)地調(diào)研,了解國內(nèi)沼氣工程產(chǎn)業(yè)的發(fā)展現(xiàn)狀及存在的問題。在研究沼氣工程技術(shù)及工藝的基礎(chǔ)上,對沼氣成分及燃爆特性進(jìn)行了分析。構(gòu)建了沼氣發(fā)酵廠房和室外儲(chǔ)罐發(fā)生火災(zāi)爆炸的故障樹,進(jìn)行了定性和定量分析,找到了導(dǎo)致事故的薄弱環(huán)節(jié)和關(guān)鍵因素,并計(jì)算得到了發(fā)生火災(zāi)爆炸事故的概率。用道化學(xué)公司的火災(zāi)爆炸指數(shù)法對沼氣工程的主裝置區(qū)和儲(chǔ)罐區(qū)的火災(zāi)爆炸危險(xiǎn)性進(jìn)行評(píng)價(jià),確定了其工藝危險(xiǎn)系數(shù)和安全補(bǔ)償系數(shù),并最終確定了其火災(zāi)爆炸危險(xiǎn)等級(jí)。針對沼氣泄漏后可能發(fā)生的閃火、氣云爆炸、穩(wěn)態(tài)燃燒以及可能進(jìn)一步引發(fā)的沼氣儲(chǔ)罐爆炸進(jìn)行定量分析,通過計(jì)算得到其安全半徑和死亡半徑,并詳細(xì)列出了人體不同損傷程度的區(qū)間。在分析沼氣燃爆特性的基礎(chǔ)上,科學(xué)地確定了沼氣沼氣儲(chǔ)罐與各個(gè)建構(gòu)筑物的防火間距。從總平面布置、防火分區(qū)、防火間距、生產(chǎn)工藝、設(shè)備安全、安全防護(hù)、消防設(shè)施、安全色、安全標(biāo)志八個(gè)方面研究了沼氣工程安全技術(shù)。最后對沼氣工程中存在的安全隱患進(jìn)行詳細(xì)分析,并提出了針對性的整改措施。本文的研究工作可以為制定沼氣工程安全技術(shù)規(guī)程、設(shè)計(jì)規(guī)范以及企業(yè)制定安全管理制度提供依據(jù)。
[Abstract]:With the rapid development of economy, the global energy crisis and environmental pollution are increasingly prominent. As a clean, non-polluting and renewable biomass energy, biogas can effectively alleviate the energy and environmental crisis. In recent years, the biogas engineering industry in China has been developed on a large scale under the impetus of national policies, but the safety problems have not been given due attention, leaving a serious accident hidden trouble. In this paper, the current situation and problems of biogas engineering industry in China are studied through literature review and field investigation. Based on the study of biogas engineering technology and technology, the composition and explosion characteristics of biogas were analyzed. The fault tree of fire and explosion in biogas fermenting workshop and outdoor storage tank is constructed. The qualitative and quantitative analysis are carried out, the weak links and key factors leading to the accident are found, and the probability of fire explosion accident is calculated. The fire and explosion risk of biogas engineering is evaluated by the fire explosion index method of Dow Chemical Company. The technological hazard coefficient and safety compensation coefficient are determined, and the fire explosion hazard grade is finally determined. Aiming at the possible flash fire, gas cloud explosion, steady state combustion and the explosion of biogas storage tank that may occur after biogas leakage, the safety radius and death radius of biogas storage tank can be obtained by calculating. The interval of different degree of human injury is listed in detail. Based on the analysis of the characteristics of biogas explosion, the distance between biogas storage tank and each building structure was scientifically determined. The safety technology of biogas engineering is studied from eight aspects: general layout, fire protection, fire prevention, production process, equipment safety, safety protection, fire fighting facilities, safety color and safety marking. Finally, the hidden danger of biogas engineering is analyzed in detail, and the corresponding measures are put forward. The research work in this paper can provide the basis for drawing up the safety technical specification, design specification and safety management system of biogas engineering.
