Description
Technical Field
The invention belongs to the technical field of detection, and particularly relates to an in-situ rapid detection device for oil mine quality based on a multi-gas-sensitive sensing system.
Background
In the field of oil mine quality detection, gas chromatograph, mass spectrometer and the like can distinguish different types of quality of oil mine, and have higher detection precision. However, at present, when the oil mine resource evaluation instrument in China is used, a sample needs to be carried to a laboratory, the pretreatment operation is complicated, the price is high, and the efficient in-situ detection on the site cannot be realized. In addition, existing technical methods for detecting the oil content quality of oil ores require rock pyrolysis, low-temperature carbonization and the like, and a great deal of extra energy is consumed in the methods. When the oil mine is mined, different heating temperatures, heating times and gas collecting times are adopted according to different quality and distribution conditions of the oil mine, quality parameters such as oil content and ash content of the oil mine in the collection area are known in advance, and whether a specific area has development value or not is considered to have important engineering significance.
Therefore, a detection technique that improves detection efficiency and reduces power consumption is needed. The electronic nose system can respond to volatile organic compounds of the oil mine through the gas sensor array, and a quality recognition result can be obtained after pattern recognition analysis.
Grinding rock samples can rapidly crush the rock mass to increase the surface area resulting in internal gas volatilization which is also an important information representing the quality of the oil mine. However, the rock debris particles can adhere to the surface of the gas sensor, which affects the accuracy of the sensor. Therefore, the problem of particulate matter removal needs to be considered, and at present, a multi-gas-sensitive sensing system which utilizes a chamber structure and a sampling mode in a combined way to optimize the dustproof effect is not needed.
The dustproof sampling optimization of the multi-gas sensor array cavity structure has very ideal advantages from the bionics point of view by utilizing living characteristics of living things. The sardine exendin is a desert animal living in a dust-rich granular environment, and can adapt to the dust-rich environment in life activities such as underground respiration, advancing foraging and the like. The special structure of the nasal cavity can block sand grains inhaled into the nasal cavity in a specific area at the front end of the nasal cavity, and the sand grains blocked and accumulated in the nasal cavity are ejected out of the body through severe cough and expiration. The behaviors of removing nasal cavity sand grains through the sardine exendin nasal cavity structure and the violent expiration are applied to the sampling cavity structure and the sampling mode of the multi-gas-sensitive sensing system, so that dust-proof sampling of the multi-gas-sensitive sensing system is realized.

The whole gas transmission process can ensure that the characteristic smell generated by the grinding oil mine cannot be diffused and lost.
The dust-proof nasal cavity chamber is designed by spraying dust deposited in a special nasal cavity area out of a human body through Sha Keli of the nasal cavity through short-time and rapid cough and expiration in a sandy and dusty living environment, and provides clean and pollution-free smell information for olfactory organs of the human body. The airflow enters the dust fall cavity channel 13 after passing through the air inlet cavity channel 11, and is provided with a unique sardine-imitated nasal cavity expansion structure, so that strong cross flow is generated in the cavity during slow air suction. The resulting cross flow enhances the effect of gravity settling, forcing the debris particles in the suction airstream to move to the wall of one side of the chamber, causing the debris that interferes with the accuracy of sensor detection to settle into the dust collection channel 15 area, while ensuring that volatile organic gas molecules are transported to the sensor array area of the rear sensing channel 14. The gas sensor array is responsible for identifying volatile organic compounds generated by oil scraps, and is radially distributed on the chamber wall, so that the uniform and smooth flow of air through each sensor surface in the whole detection process is ensured.

Under the odor collection and air suction working condition, when grinding is finished, the singlechip controller E controls the electromagnetic valve I4 to be opened, the air pump is operated to suck air, carrier gas containing oilmine odor and rock debris particles is conveyed to the detection area of the gas sensor array, meanwhile, the carrier gas is matched with the sardine-like exendin cavity to intercept the rock debris particles to the sedimentation area, and the acquisition of oilmine odor signals is completed; under the dust removal and exhaust working condition, the singlechip controller E controls the air pump to change the working voltage to reversely run and exhaust so as to generate enough air flow and pressure, and oil and mineral scraps particles deposited in the designated area of the simulated sardine nasal cavity chamber are flushed out of the chamber to the dust collection box F area, so that the dust removal operation is completed. The resistivity of the gas sensor array 19 changes after the gas sensor array contacts volatile oil mine gas, and the voltage signal of the sensor array is converted into oil mine quality smell information which is collected and stored through the A/D collection module 21.
The working process of the invention is as follows: and (3) connecting the grinder containing the sample to be detected into the device after the step (1) is finished, performing the cyclic detection flow of the step (2) and the step (3), finishing detection after the cyclic detection is finished for a certain number of times, and collecting and storing response signals of the sensor array into a computer for subsequent pattern recognition classification and rock sample database recording.

After finishing grinding, the electromagnetic valve I4 is controlled to be opened and the electromagnetic valve II 6 is controlled to be closed through the singlechip controller E. The gas sensor array 19 is energized and sensor response signals are acquired and stored using the a/D acquisition module 21. An electromagnetic switch 2 for controlling the ventilation of a gas cylinder 1 containing nitrogen carrier gas is opened, and a gas pump 5 operates for sucking gas. The air suction mode simulates the air suction mode of the sardine in the sand underground, the air pump 5 is adjusted to flow of 1L/min, and the carrier gas conveys and sucks the mixed gas to be tested containing the rock debris to the sardine simulated dustproof cavity D after passing through the grinder B. After the gas to be detected and the rock debris particles pass through the chamber, the rock debris particles are deposited in the dust collection cavity 15 area at the rear end of the dust prevention chamber D imitating the sardine, and clean carrier gas and volatile smell of the object to be detected are detected by the gas sensor array 19 and then discharged out of the system.
Step 3: and (5) exhausting. The electromagnetic valve I4 is controlled to be closed by the singlechip controller E, the electromagnetic valve II 6 is opened, the electromagnetic switch 2 is controlled to be closed to the carrier gas cylinder 1, the air pump 5 reversely operates to exhaust, the exhaust mode imitates the exhaling mode of the sardine under sand, the air pump 5 is regulated to flow of 30L/min, the particulate matters deposited in the dust collection cavity 15 area in the imitated sardine dustproof cavity D are discharged into the dust collection box F through violent exhaling, and the filter screen 18 is arranged at the bottom of the dust collection box F and used for intercepting the rock debris particulate matters.
The invention has the beneficial effects that:
1. the rock sample can be broken conveniently and rapidly by using the grinder, and volatile gas of the quality information of the oil-bearing ore is obtained.
2. The grinder is used with a multi-gas-sensitive sensing system, the whole air tightness of the device is good, and the loss of the rock debris smell information can be reduced to the greatest extent.
3. The respiratory gas collection and dust removal can ensure the stable pressure drop of the gas collection air flow and reduce the interference of particulate matters on the gas sensor.
4.
