Domain.
Background technology
Coal seam gas-bearing capacity is one of most basic parameter of coal-bed gas, and its assay method can be divided into direct method and indirect method
Two big class.The maximum problem of Direct Determination coal seam gas-bearing capacity be drill through coal sample during gas loss cause evaluated error.
For down-sampling process gas loss amount, improve gas bearing capacity and measure accuracy it is proposed that immediately in sampler after the completion of sampling
Mouth sealing fluid sealing coal sample, coal sample desorption of mash gas in suppression sampler, thus reduce coal sample gas loss.For detecting sealing fluid
Suppression coal sample desorbing gas effect and influence factor, need the device that a kind of simulation sealing fluid suppresses coal sample desorbing gas badly.
Content of the invention
For the problems referred to above, it is an object of the invention to provide a kind of simulation sealing fluid suppress coal sample desorbing gas device and
Method.
For achieving the above object, the present invention takes a kind of technical scheme below: simulation sealing fluid suppression coal sample desorbing gas
Device it is characterised in that: include a support, on the bracket rotate connect a horizontally disposed rotating shaft, described rotating shaft with
One tank body is fastenedly connected, and described tank body is divided into upper tank body and lower tank by a sieve tray by described tank interior, described on
Tank body is connected with the outlet of a distribution tank by pipeline, and the import of described distribution tank is connected with a gas bottle by pipeline；Described
Lower tank is connected by the desorption tube that pipeline is upside down in tank with；Between described distribution tank and described upper tank body
First valve is arranged on pipeline, the pipeline between described desorption tube and described lower tank arranges the second valve.
It is fastenedly connected a turning handle in one end of described rotating shaft.
A kind of method that simulation sealing fluid suppresses coal sample desorbing gas, comprises the following steps: 1) coal sample is placed on upper tank
In body, sealing fluid is filled lower tank, water is filled tank；2) open gas bottle to inflate to distribution tank, when gas in distribution tank
Gas pressure opens the first valve after reaching predetermined value, and methane gas are filled in upper tank body, and keeps a period of time to make coal
Sample adsorption gas reach balance；3) close distribution tank, rotating shaft makes tank body rotate 180 °, makes lower tank be located at top, upper tank
