Abstract

The invention relates to a gas desorption instrument. The gas desorption instrument comprises a measuring tube, an exhaust rubber tube and a puncture needle; an upper cover is arranged on the top of the measuring tube; a hoisting ring is arranged on the upper cover; a base is arranged at the bottom of the measuring tube; the base is provided with a water inlet; a plug is arranged on the water inlet; a water outlet is formed between the base and the measuring tube; a hose is arranged in the measuring tube; the base is provided with an air inlet; the hose is connected with the exhaust rubber tube through the air inlet; the exhaust rubber tube is connected with a coal sample tank through the puncture needle; and a spring clip is arranged on the exhaust rubber tube. The gas desorption instrument is simple and compact in structure, small in size, light in weight, easy to transport, convenient to carry and low in water consumption, facilitates wild or underground operation, and is suitable for water-free measuring sites; because the hoisting ring is arranged on the upper cover and the base is arranged at the lower end of the measuring tube, the instrument is easy to level; and when the instrument is used, the hoisting ring can be tied on a rope to hoist the instrument, or the instrument is placed on a horizontal plane.

Description

technical field [0001] The invention belongs to the technical field of coal seam gas content measurement, in particular to a gas desorption instrument. Background technique [0002] The direct methods for coal seam gas content determination include: geological exploration borehole gas desorption method, downhole borehole gas desorption method and coal core extractor method, etc. The basic method is to take coal cuttings or coal cores when the coal seam is just exposed, quickly put them into an airtight container, measure the desorption speed and desorption amount Q2, use the desorption law to deduce and compensate the total amount Q1 of the escaped part during the sample collection process, and then Go back to the laboratory to measure the remaining amount of gas Q3 in the coal sample, and finally get the gas content Q=Q1+Q2+Q3. In the process of measuring the gas residual quantity Q3 in the laboratory, first use the degassing device to measure the gas quantity Q31 b...
