Based on the problems, the invention provides a radio frequency heating oil-rich coal in-situ pyrolysis simulation test device which is used for researching the effect of radio frequency heating on in-situ pyrolysis of oil-rich coal.
As shown in fig. 1 and fig. 2, the in-situ pyrolysis simulation test device for the radio frequency heating oil-rich coal provided by the invention comprises: the cavity 5 is of a cylindrical structure with one end open, a perforated baffle 6 is arranged in the cavity 5, and the perforated baffle 6 divides the cavity 5 into a rich coal accommodating cavity and a tar accommodating cavity; the gas collecting bag 1 is connected with the cavity 5 through a gas collecting valve 2-1; a cavity cover 3 covering an opening of the cavity 5; the radio frequency control device 11, the radio frequency antenna 10 of the radio frequency control device 11 inserts in the cavity 5, is used for heating the rich coal 4 in the rich coal holding cavity. The side wall of the cavity 5 is provided with a temperature measuring hole 3, and the bottom of the cavity 5 is provided with a tar collecting valve 2-2.
Further, a groove is formed in the cavity cover 8, a packing 7 is arranged in the groove, a through hole for the radio frequency antenna 10 to penetrate is formed in the cavity cover 8, an antenna protection barrel 9 is further arranged in the cavity 5, and the antenna protection barrel 9 is sleeved outside the radio frequency antenna 10.
Further, the antenna protection tube 9 is a protection tube that does not absorb electromagnetic waves, and is preferably a polytetrafluoroethylene protection tube.
The invention also relates to an experimental method based on the radio frequency heating oil-rich coal in-situ pyrolysis simulation test device, which comprises the following steps:
step 1: preparing the rich oil coal, detecting the components of the rich oil coal sample in advance, and estimating pyrolysis products according to the existing literature data. The placed rich oil coal is a blocky coal sample, so that excessive coal dust is prevented from entering the space below the porous partition plate to influence tar collection.
Step 2: the oil-rich coal sample is placed on the perforated baffle plate 6 in the cavity 5 as regularly as possible, and the oil-rich coal sample is placed lightly in the placing process, so that the experimental device is prevented from being damaged. Because the oil-rich coal is placed on the perforated baffle plate 6 in the cavity 5, tar generated after pyrolysis of the oil-rich coal is collected in a space below the perforated baffle plate 6.
The method comprises the following steps: the connection of the gas collecting bag 1 is carried out, the connection of the gas collecting bag 1 is ensured to ensure that the gas collecting bag 1 is intact and the connection with the gas collecting valve 2-1 is stable, and the valve is confirmed to be opened.
Step 4: checking whether the cavity cover 8 and the packing 7 of the cavity 5 are intact, covering the cavity cover 8 and ensuring fixation, and checking whether the tar collecting valve 2-2 at the bottom of the cavity 5 is closed. Before the cavity cover 8 is covered, the integrity of the graphite packing 7 is ensured to achieve a certain sealing effect, and the cavity cover 8 needs a certain fixing measure.
Step 5: the power is set according to the actual requirement through the radio frequency control device 11, the device is started after all equipment is normal, the professional equipment (leakage detector) is used for monitoring whether electromagnetic waves leak at any time after the device is started, the temperature of the inside of the cavity 5 is measured through the temperature measuring hole 3 after the device is heated for a certain time, if the heating should be stopped due to abnormal high temperature, if the temperature in the cavity 5 is required to be continuously monitored, the temperature measuring rod is inserted into the cavity 5 and is not taken out, but the temperature measuring rod is required to be resistant to high temperature (450 ℃). The temperature measurement through the temperature measuring hole 3 is carried out by using a high temperature resistant temperature measuring rod which enters the cavity 5 through the temperature measuring hole 3, and the temperature of the cavity 5 at different radial distances is measured. In this process, since high temperature is generated in the cavity 5, the temperature cannot be monitored by the built-in thermometer, and if the purpose of real-time temperature monitoring is to be achieved, the temperature must be measured by the high temperature resistant thermometer.
Step 6: the gas was collected. When heating starts, the condition of the gas collecting bag 1 must be paid attention to, when the gas collecting bag 1 has a large expansion range, the gas collecting valve 2-1 must be closed to replace the gas collecting bag 1, and then the valve is opened, so that the gas collecting bag 1 needs to have special storage protection measures to prevent damage and leakage. The gas collection bag 1 or other devices capable of visually observing the gas collection phenomenon are used for collecting the gas. When the gas collecting bag 1 is used for collecting, if the gas collecting bag 1 is observed to be greatly inflated, the valve is closed to replace the gas collecting bag 1, and the gas is inflammable and explosive, so that the collected gas is required to be properly stored.
Step 7: heating is stopped when no gas is generated or the experimental requirements have been met. Here, no gas is generated, that is, the gas collecting bag 1 does not continue to expand.
Step 8: after stopping the heating, the liquid product is taken out from the bottom of the cavity 5. The container for holding the liquid has the characteristic of high temperature resistance, and the heat-insulating glove is worn when the valve is opened.
Step 9: the cavity cover 8 is opened by wearing the heat-insulating glove, and the heat is dissipated to the room temperature. At this time, the remaining gas in the chamber 5 is not discharged, and a certain protection measure is performed when the chamber cover 8 is opened.
Step 10: the remainder of the cavity 5 is removed and the interior of the cavity 5 is cleaned with professional equipment. It should be noted that, the liquid below the perforated baffle plate 6 in the cavity 5 cannot be completely discharged through the valve at the bottom of the cavity 5, and the perforated baffle plate 6 needs to be removed to collect the residual liquid after cleaning the residues in the cavity 5.
The experimental device can control the power and the frequency of radio frequency heating through the radio frequency control device, can judge whether the pyrolysis process in the cavity is finished through the simple device of the gas collecting bag, and can realize dry-wet separation of liquid and residual residues generated in the pyrolysis process of the oil-rich coal, thereby better collecting the liquid.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
