Description

一种煤矿乏风及抽放瓦斯的掺混处理系统 One kind of coal mine ventilation air methane drainage and blending processing system

技术领域 FIELD

[0001]本发明涉及煤矿节能减排、煤矿安全技术及工程领域,具体涉及一种煤矿乏风及抽放瓦斯的掺混处理系统。 [0001] The present invention relates to energy conservation, coal mine safety technology and engineering, in particular to a coal mine drainage gas and ventilation air system of the blending process.

背景技术 Background technique

[0002]煤矿在生产过程中,煤层中贮存的大量瓦斯会涌到采掘空间,为保证煤矿地下矿井中空气的安全、健康,需要向地下矿井鼓入大量新风,这些气流携带极低浓度的甲烷(低于0 • 75%)从地下经回风口排到大气里,俗称“风排瓦斯”或“乏风”。 [0002] coal in the production process, the coal seam storage of a large number of gas will flock to the mining space, in order to ensure the safety of coal underground mines in the air, health, requires large volumes of fresh air to the underground mine drum, these streams carry a very low concentration of methane (less than 0 • 75%) from the ground through the return air discharged to the atmosphere, commonly known as "VAM" or "lack of wind."

[0003] 尤其是在一些高瓦斯矿井,由于其工作面的瓦斯浓度远远超出《煤矿安全规程》所规定的标准,单纯采用通风的方法难以把工作面的瓦斯浓度控制在允许的范围内;在煤与瓦斯突出矿井,突出的危险也严重威胁着矿井工作人员的生命安全,制约着矿井的正常生产。 [0003] In some particularly high gas coal mine, since the gas concentration far beyond the face of its standard "Coal Mine Safety Regulations" specified, only using the method of ventilation is difficult to face the gas concentration is controlled within the allowable range; in danger of coal and gas outburst, but also highlight the serious threat to the lives and safety of mine workers, restricts the normal production of the mine. 在此情况下,必须采取瓦斯抽放的方式来改善矿井的安全生产状况,缓解生产压力。 In this case, we must take the gas drainage ways to improve safety conditions in the mine, to ease the production of pressure.

[0004] 为了减少和解除矿井瓦斯对煤矿安全生产的威胁,利用机械设备和专用管道造成的负压,将煤(岩)层中赋存或释放的瓦斯抽出来,输送到地面或其他安全地点的做法,叫做瓦斯抽放。 [0004] In order to release and reduce the threat to the safety of mine gas coal mine production, the negative pressure caused by piping and special machinery, and coal (rock) layer or occurrence of gas release it out, transported to the ground or other safe location the practice, called gas drainage.

[0005] 据统计,我国煤矿每年通过瓦斯抽放排入到大气中的甲烷总量在240亿立方米以上。 [0005] According to statistics, China's coal mine gas drainage year by the total amount of methane discharged into the atmosphere of more than 24 billion cubic meters. 甲烷气体具有很强的温室效应,相当于二氧化碳的25倍。 Methane gas has a strong greenhouse effect, equivalent to 25 times that of CO2. 甲烷在空气中的爆炸极限为5%〜16%。 Explosion limit of methane in air is 5% ~ 16%. 煤矿瓦斯分高浓度瓦斯和低浓度瓦斯,高浓度瓦斯是指瓦斯浓度大于30%的瓦斯,低浓度瓦斯是指瓦斯浓度低于30%的瓦斯。 Coal mine gas from high concentrations of methane gas and low-concentration, high density gas refers to a gas concentration of gas greater than 30%, low concentration gas means gas concentration is less than 30% of the gas. 我国60%以上的瓦斯是含甲烷30%以下的低浓度瓦斯,按煤矿安全规程要求,瓦斯浓度在30%以下的就不能进储气罐贮存,大部分直接对空排放。 60% or more methane-containing gas of low concentration gas is 30% or less, by mine safety regulations requirements, gas concentration of 30% or less can not enter the storage tank, most of the direct-to-air emissions. 煤矿低浓度抽放瓦斯的直接排放一方面造成了不可再生资源的巨大浪费,另一方面也加剧了大气污染和温室效应。 Direct discharge of low concentrations of coal mine gas drainage of the hand caused a huge waste of non-renewable resources, on the other hand also contributed to air pollution and the greenhouse effect.

[0006] 对乏风及低浓度抽放瓦斯实现采集与输送,并通过对瓦斯的氧化处理来消除原来排放到大气中的甲烷,使之氧化为二氧化碳和水,从而产生巨大的温室气体减排效应。 [0006] The ventilation air and drainage gas to achieve low concentrations of collection and delivery, and treatment by the oxidation of the exhaust gas to eliminate the original methane in the atmosphere, so that oxidation to carbon dioxide and water, resulting in a huge greenhouse gas emissions effect. 因此,如何安全有效的对煤矿乏风及低浓度抽放瓦斯进行采集与输送显得尤为重要。 So how safe and effective for low concentrations of coal mine ventilation air and gas drainage collection and transport is very important.
