Monitoring process and principle：
The moulded coal 1 of detection is put on multiple gravity sensors 5 in reaction kettle 2, arranged around moulded coal 1 multiple
Temperature sensor and multiple pressure sensors, multiple gravity sensors 5, multiple temperature sensors and multiple pressure sensors are led
Line is pierced by pressurizing block 3, installs pressurizing block 3, connects the hydraulic stem of hydraulic pump 4 being connect with pressurizing block 3, and inspection ensures high pressure
Be tightly connected between water pipe 9, air inlet pipe 12 and exhaust pipe 15 and pressurizing block 3, at the same make the first solenoid valve 8, second solenoid valve 11,
Third solenoid valve 14 is closed, and reaction kettle 2 is put into constant temperature water tank 6.
Starting third solenoid valve 14 makes vacuum pump 13 start to work, and the air of hole and surrounding to moulded coal 1 carries out
Suction controls the vacuum degree in moulded coal 1 by vacuum meter, after vacuum degree reaches sets requirement, closes third solenoid valve 14 and stops
Only vacuumize.
Start the first solenoid valve 8 and second solenoid valve 11, high pressure water is passed through into reaction kettle 2 by high-pressure hydraulic pump 7, is passed through
Gas storage tank 10 is passed through methane gas into reaction kettle 2, while passes through the temperature in multiple temperature sensor monitors reaction kettles 2
Degree controls the temperature in reaction kettle 2, while pass through multiple 2 inner mold of pressure sensor monitoring reaction kettle by temperature controller 19
The pressure that coal is subject to controls hydraulic stem to move up and down, so as to control the pressure that moulded coal 1 is subject in reaction kettle 2 by hydraulic cylinder 4.
Reaction kettle 2 is barrel-shaped, and moulded coal 1 is also cylinder, and the diameter of moulded coal 1 matches with the internal diameter size of reaction kettle 2,
Since the effect of power is mutual, pressure is applied to moulded coal 1 by hydraulic stem and pressurizing block by hydraulic cylinder 4, in reaction kettle 2
Under limitation, so as to simulate the confining pressure that moulded coal is subject to, convenient test, hydraulic cylinder 4 applies moulded coal by hydraulic stem, pressurizing block 1
Pressure cannot deform upon reaction kettle 2 and moulded coal 1, while the sum of weight for adding moulded coal to the pressure that moulded coal 1 applies is no more than
The detection range of gravity sensor.
Methane gas shuttles between the hole of moulded coal 1, crystal gas is formed under the collective effect of temperature, pressure and water
Hydrate, due to the generation of crystal Gas Hydrate, the gas pressure monitored by pressure gauge 20 in reaction kettle 2 is reduced, is calculated
Machine 18 controls second solenoid valve 11 so that gas storage tank 10 inputs methane gas into reaction kettle 2, simultaneously because crystal gas
The generation of hydrate so that the weight of moulded coal 1 increases, and after keeping set period of time, the weight of moulded coal 1 is not further added by, while anti-
When answering the gas pressure in kettle 2 to increase to over the setting value of air gauge 20, i.e., Gas Hydrate is in saturation state.
Since the lower part of moulded coal 1 is equipped with multiple weight sensors 5, extra high pressure water keeps the bottom of reaction kettle,
The monitor value of weight sensor 5 is not interfered with.
The present invention is by the hydraulic stem of pressurizing block connection liquid cylinder pressure, according to the data of multiple pressure sensors in reaction kettle
Hydraulic cylinder is controlled to apply pressure to pressurizing block by hydraulic stem, so as to apply pressure to the moulded coal in reaction kettle, according to multiple temperature
The data of sensor are spent, computer control temperature controller heats constant temperature water tank, adds so as to carry out constant temperature to reaction kettle
Heat is monitored the air pressure of methane gas in reaction kettle by air gauge, by the input of second solenoid valve control gas gas, passed through
The input of first solenoid valve control high pressure water monitors the weight change of moulded coal by multiple weight sensors, when the weight of moulded coal
When no longer changing gas pressure increase simultaneously, i.e., Gas Hydrate is in saturation state, this monitoring device is simple in structure, automation
Control, it is easy to use, different pressures are applied to moulded coal by hydraulic cylinder and pressurizing block, by changing the temperature in reaction kettle, are led to
The weight change of weight sensor monitor-type coal is crossed, so as to monitor the saturation degree of Gas Hydrate.
Disclosed above is only several specific embodiments of the present invention, and still, the embodiment of the present invention is not limited to this, is appointed
