煤矿瓦斯用的细水雾输送装置
摘要：
本实用新型是一种煤矿瓦斯用的细水雾输送装置。属于低浓度煤矿瓦斯长距离安全输送技术领域，涉及到细水雾发生器。由水环真空泵、阻火器、瓦斯管道、排空阀、输气阀、细水雾发生器、脱水器、除水器和连接法兰组成。水环真空泵的进口连接煤矿井下瓦斯管道，其出口连接阻火器，再连接瓦斯管道。瓦斯管道分两路，一路连接排空阀，另一路依次连接阻火器、输气阀、细水雾发生器、脱水器、阻火器、除水器、阻火器和瓦斯发电机组。细水雾发生器由混合管道、喷雾嘴、控制阀、水管道、水泵、蓄水箱和水过滤器组成，并依次连接。解决了低浓度煤矿瓦斯长距离安全输送技术难题，使煤矿瓦斯不再排空，用来发电，节约能源，利于环保，经济效益和社会效益显著。
摘要（英）：

The utility model discloses a fine spray supplying device for gas in a coal mine, which belongs to the technical field of the long-distance safe conveying of gas having low concentration in a coal mine and relates to a fine spray generator. The utility model is composed of a water ring vacuum pump, a flame arrester, a gas pipeline, an emptying valve, an air supplying valve, the fine spray generator, a dehydrator, a water remover and a connecting flange, wherein an inlet of the water ring vacuum pump is connected with the gas pipeline of an underground coal mine and an outlet of the water ring vacuum pump is connected with the flame arrester and then connected with the gas pipeline. The gas pipeline has two paths, one path is connected with the emptying valve, and the other path is orderly connected with the flame arrester, the air supplying valve, the fine spray generator, the dehydrator, the flame arrester, the water remover, the flame arrester and a gas generating set. The fine spray generator is composed of a mixed pipeline, a spray nozzle, a control valve, a water pipeline, a water pump, a water storing tank and a water filter which are connected in turn. The technical problem of the long-distance safe conveying of the gas having low concentration in the coal mine is solved, and the gas in the coal mine can not be emptied and can be used for generating electricity with the advantages of energy saving and environmental protection.
