论文中文摘要:
在我国煤矿事故频繁发生,而且由于事故救灾措施及设施不完善,经常造成重大人员伤亡。因此,为了避免事故造成人员伤亡,国家安全生产总局提出了在矿井下建立矿井救灾“六大避难系统”,矿用救生舱就是其中之一。然而矿用救生舱内的空调系统还没有一个统一方案。本文在查阅相关国内外文献的基础上,对8人矿井固定救生舱中的空调系统做了比较深入的研究,为矿用救生舱内空调系统设计提供了选择依据。 首先,对矿用救生舱内空调负荷进行了分析,并提出了可行的计算方法,对所研究的救生舱而言,在96h舱内得热量为7. 1×105KJ,散湿量为96.12kg,耗氧量为1234.3mol,放出CO2量为1028.57mol。 其次,从保证舱内空气品质出发,对舱内的CO2、CO的处理方法及供氧方式进行研究。研究表明:从经济上和占用救生舱内有效容积考虑,选用 Na2O2吸收法处理CO2比较合理;处理CO采用活性炭和稀释相结合的方法;供氧方式优先选用压风管道,若压风管道破坏,则采用化学供氧和储存氧相结合的方法;过渡舱内设置空气幕保证舱内正压。 第三,提出了救生舱的6种空调系统方案,包括防爆空调系统(方案I),CO2空调系统(方案II),NH3系统(方案III),固体吸附系统(方案IV),冰蓄冷系统(方案V)以及涡流管制冷系统(方案VI)。 第四,从安全、经济、占用救生舱内有效容积、可靠运行等方面研究了上述各方案的特征。得出单独利用涡流管制冷技术需求压缩空气量过于庞大,不适宜单独应用于救生舱制冷技术;从安全角度分析,CO2,NH3系统在使用时要注意防漏,使用这两种方案时,需考虑可能带来的影响;固体吸附及蓄冷空调技术是比较好的方案,通过对除方案VI外各空调系统的现值成本分析,得出PCI=59193.6元,PCII=74289.8元,PCIII=19667.9元,PCIV=47606.98元,PCV=76719.97元,可以看出PCI最低其次是PCIV。从安全、占有救生舱内有效容积及现值成本综合考虑分析,最佳方案为固体吸附制冷系统。
论文外文摘要:
Coal mine accidents frequently happen in China, because the accident relief measures and facilities are not perfect, often cause heavy casualties. Therefore, in order to avoid accidents, the National Production Administration proposed the establishment of the mine disaster "six evacuation system", mine rescue is one of them. However, the air-conditioning system of mine rescue capsule is not a unified scheme. This paper based on the 8 mine fixed lifesaving cabin to do the following work on the air-conditioning system and acquire the conclusions as follow. First of all,the calculation of load inside the capsule is analyzed, and puts forward the feasible calculation method.The 96h lifesaving cabin heat is 7. 1 × 105KJ, moisture content is 96.128kg, the oxygen releases of 1234.3mol, and releases of CO2 is 1028.57mol; Secondly, from the point of ensuring the cabin air quality, methods on dealing with the CO2, CO of the cabin and oxygen supply mode are researched. Research shows that: from the economic and the occupation volume inside the capsule to consider, chooses Na2O2 absorption treatment of CO2 is more reasonable;the method of dealing with CO by active carbon combined with dilution; oxygen supply mode preferred compressed air pipe , if the air pressure pipeline is failure, using method of chemical oxygen supply and oxygen storage combined air setting; transition cabin scene to ensure that the cabin pressure. Third, this paper puts forward 6 kinds of air conditioning system for the rescue capsule, including explosion proof air conditioning system (I), CO2 air conditioning system (II), NH3 system (III), solid adsorption system (IV), ice storage system (V) and vortex tube cooling system (VI). Fourth, from security, economy, occupied volume inside the capsule ,reliable operation of the system, and other aspects of the project are considered. That alone using vortex tube refrigeration technology demand quantity of compressed air is too large, not suitable for lifesaving cabin as separate refrigeration technology; from the point of security analysis, CO2 and NH3 system should pay attention to leaking, when the use of these two schemes need to consider the possible impacts; solid adsorption and thermal storage air-conditioning technology is good solution, through the analysis of present value of costs on the removal of VI of the air conditioning system, obtains the PCI=59193.6 yuan, PCII=74289.8 yuan, PCIII=19667.9 yuan, PCIV=47606.98 yuan,PCV=76719.97 yuan, can be seen the lowest PCI followed by PCIV. Analysis of possession security, from inside the capsule effective volume and value considering the costs, the best solution is the solid adsorption refrigeration system.
