The utility model provides a coal-bed methane filtering device, which mainly relates to the field of coalbed methane extraction. A coalbed methane filtering device includes an inlet pipe, a dust removing pipe is arranged at one end of the inlet pipe, a filter cotton is filled in the dust removing pipe, a first connecting pipe is arranged at one end of the inlet pipe, a grid plate is arranged between the first connecting pipe and the dust removing pipe, and a water removing tank is arranged at one end of the first connecting pipe away from the dust removing pipe. A second connecting pipe is arranged at one end of the first connecting pipe away from the water tank, and the second connecting pipe is far away from one end of the water tank, and a drying cavity is arranged with a water absorbing sponge, and the drying cavity is far away from one end of the second connecting pipe and an output pipe is arranged. The utility model has the beneficial effect that the dust material and water contained in the coal bed gas can be effectively removed, the dust material can be avoided blocking the valve, the corrosion rate of the inner wall of the gas pipeline can be slowed down, the service life of the gas pipeline and the valve can be increased, and the probability of safety accidents can be reduced.

煤层气过滤装置
本技术主要涉及煤层气开采领域,具体是煤层气过滤装置。
技术介绍
煤层气是指储存在煤层中以甲烷为主要成分、以吸附在煤基质颗粒表面为主、部分游离于煤孔隙中或溶解于煤层水中的烃类气体,是煤的伴生矿产资源,属非常规天然气,是近一二十年在国际上崛起的洁净、优质能源和化工原料。煤层气俗称“瓦斯”,热值是通用煤的2-5倍,1立方米纯煤层气的热值相当于1.13kg汽油、1.21kg标准煤,其热值与天然气相当,可以与天然气混输混用,而且燃烧后很洁净,几乎不产生任何废气,是上好的工业、化工、发电和居民生活燃料。煤层气可以用作民用燃料、工业燃料、发电燃料、汽车燃料和重要的化工原料,用途非常广泛。我国对于煤层气的开采多是采用排水降压的方式进行开采,由于煤层气是以吸附态为主吸附于煤层孔隙中,因此开采出来的煤层气带有大量的粉尘物质和水分,这种煤层气在管道输送过程中存在以下安全隐患:1、现在我国采用的输气管道多为金属材质,含有大量水分的煤层气会使金属输气管道内壁的锈蚀速度加快,减少输气管道的使用寿命,锈蚀的管道会产生大量铁屑,使得输气管道尽头的压力泵吸入杂质受损,甚至引发煤层气 ...
