Abstract
The utility model relates to a high-precision desorber. The measuring range of the conventional gas desorber cannot satisfy the low coal-bed methane (coal-mine gas) content measuring precision requirements at the existing stage; moreover, the common gas desorber is made of hard transparent plastic, easily causes inaccurate reading when the temperature is higher and incapable of being continuously used due to direct plastic frost cracking a under cold weather condition. The high-precision desorber comprises a large measuring cylinder, a water storage device, a communicating tube and a quick joint, wherein the top of the large measuring cylinder is communicated with the quick joint by the communicating tube; the bottom end of the large measuring cylinder is communicated with the water storage device by the communicating tube. The high-precision desorber is characterized by further comprising a small measuring cylinder, wherein the bottom end of the large measuring cylinder is communicated with the bottom end of the small measuring cylinder and the water storage device; the top of the large measuring cylinder is communicated with the top of the small measuring cylinder and the quick joint. The high-precision desorber not only is capable of realizing the precise measurement of the various coal-bed methane (coal-mine gases), but also is safe and simple to operate.
