【摘要】：我国是一个产煤大国，长期以来，煤炭在国家能源结构中占有重要地位，确保煤矿安全高效生产，是保证我国能源长期可靠供应的必然要求。煤矿是一个事故多发的行业，积极探求各种新的方法，增强煤矿的抗灾、防灾能力，对提高矿山在事故发生后的应急能力，保障矿工生命安全，减少伤亡事故的发生具有重要意义。救生舱是新近研发的一种井下救援装备，本文对救生舱内生存环境控制与优化设计方法进行研究，，论文在对舱内环境进行详细分析的基础上，提出了救生舱内环境参数控制的工程设计方法，并通过救生舱内真人实验，验证方法的合理性与可行性。为了解舱内温湿度分布规律，采用CFD数值模拟的方法，计算了12人舱舱内温湿度分布，计算结果与实测结果较好地吻合。为了更好地组织舱内气流，提高舱内舒适性，论文提出采用温度不均匀系数作为评价指标，分析比较了不同气流组织形式下的舱内温湿度分布均匀性，得出了较优的气流组织方案。在此基础上，论文研究了救生舱在非满载情况下，两风口的送风比问题，得出在8人时采用3∶2的送风比，4人时采用2∶1的送风比是比较合适的，在能满足舱内温湿度要求情况下，可实现更大的冷量节约。本文的研究结果，对救生舱的工程设计具有指导作用，有利于救生舱的优化设计的进行。
[Abstract]:China is a big coal-producing country. For a long time, coal occupies an important position in the national energy structure. To ensure the safe and efficient production of coal mine is the inevitable requirement to ensure the long-term reliable supply of energy in our country. Coal mine is an accident prone industry, actively exploring various new methods to enhance mine disaster resistance and disaster prevention ability, to improve mine emergency ability after accidents, and to ensure the safety of miners' lives. It is of great significance to reduce the incidence of casualties. The lifebuoy is a newly developed downhole rescue equipment. This paper studies the control and optimization design method of the living environment in the lifebuoy, and based on the detailed analysis of the cabin environment, The engineering design method for the control of environmental parameters in the lifebuoy is put forward, and the rationality and feasibility of the method are verified by the real human experiments in the lifebuoy. In order to understand the distribution of temperature and humidity in the cabin, the temperature and humidity distribution in the cabin of 12 people is calculated by using CFD numerical simulation method. The calculated results are in good agreement with the measured results. In order to better organize the airflow in the cabin and improve the comfort in the cabin, this paper proposes to use the non-uniform coefficient of temperature as the evaluation index, and analyzes and compares the uniformity of the distribution of temperature and humidity in the cabin under different airflow organization forms. A better airflow organization scheme is obtained. On the basis of this, the paper studies the air supply ratio of two nozzles in the case of non-full load. It is concluded that it is more appropriate to use the air supply ratio of 3:2 when the air supply ratio is 4 at 3:2 when the ratio is 2:1. In the case of meeting the requirements of cabin temperature and humidity, can achieve greater cooling savings. The research results of this paper can guide the engineering design of the lifebuoy and help to carry out the optimum design of the lifebuoy.
