[0036] The present application provides an oil and gas production device 100.

[0037] Please refer to Figure 1 In an embodiment of the present application, the oil and gas production device 100 includes a cylinder 1, an electrode assembly 2 and an ultrasonic wave assembly 3. The cylinder 1 is provided with a feed inlet 11 and a gas outlet 12. The feed inlet 11 is used to put in organic waste and clean water, and the gas outlet 12 is communicated with the outside. The electrode assembly 2 is arranged in the cylinder 1, and is used to electrolyze the clean water in the cylinder 1. The ultrasonic wave assembly 3 is arranged in the cylinder 1, and part of the structure of the ultrasonic wave assembly 3 is connected with the electrode assembly 2.

[0038] In the present embodiment, it should be noted that the oil and gas device 100 can not only be applied to oilfield stations; but also can be applied to household scenarios, outputting fuel gas for cooking and heating; but also can be applied to field power supply; but also can be applied to electric vehicle endurance. The oil and gas device 100 takes the living area garbage and biomass as organic waste, and puts the organic waste and clean water into the cylinder 1, generates hydrogen by electrolyzing water through the electrode assembly 2, and cavitation self-generating supercritical internal environment through the ultrasonic assembly 3, efficiently and quickly oxidizes organic waste to produce carbon monoxide, and at the same time under the action of ultrasonic waves of the ultrasonic assembly 3, carbon monoxide and hydrogen are synthesized into alkanes and alkenes, finally realizing the resource utilization of organic waste into high value-added oil and gas new energy. It should be noted that the cylinder 1 is used to provide a reaction space, and contains organic waste, water, electrode assembly 2 and ultrasonic assembly 3, etc., and realizes the input of organic waste and the output of oil and gas through the feeding port 11 and the gas outlet 12. The electrode assembly 2 is used to electrolyze water in the cylinder 1, and through the chemical principle of electrolyzing water, it can be known that electrolyzing water produces oxygen and hydrogen. The ultrasonic assembly 3 is used to generate high-frequency vibration, and its ultrasonic cavitation effect forms a local supercritical microenvironment under normal pressure. The ultrasonic assembly 3 generates high-frequency vibration in the cylinder 1, forming ultrasonic cavitation phenomenon. Cavitation will produce a large number of tiny bubbles in the liquid, and these bubbles will produce a local high temperature and high pressure environment (up to thousands of degrees Celsius and hundreds of atmospheres) in the growth and collapse process. The high temperature and high pressure environment generated by ultrasonic cavitation and the hydrogen generated by electrolysis of water form a synergistic effect. Hydrogen is more likely to react with organic matter in organic waste in the high temperature and high pressure environment generated by cavitation, further improving the conversion efficiency. Specifically, it can be understood that the organic waste can be plastic products in the living area, straw, grass, tree branches and leaves, and woodworking organic waste, etc., which are not limited this time.

Specifically, the cylinder body 1 is the main structure of the whole device, and is provided with a feeding port 11 and a gas outlet 12. The feeding port 11 is used for feeding organic waste and water to provide raw materials for the oil and gas production reaction, and the gas outlet 12 is used for discharging the generated oil and gas and communicating with the outside to ensure that the product can be smoothly output. The electrode assembly 2 is arranged in the cylinder body 1, and can generate hydrogen by electrolyzing the water in the cylinder body 1 to provide the necessary hydrogen source for the oil and gas production reaction. The ultrasonic wave assembly 3 is arranged in the cylinder body 1, and part of the structure is connected with the electrode assembly 2. The high-frequency vibration of the ultrasonic wave can fully stir and crush the organic waste and water, so that the organic waste and water are fully mixed, the reaction contact area is increased, and the reaction efficiency and the generation amount of the oil and gas are further improved. At the same time, the cavitation effect of the ultrasonic wave promotes the chemical reaction and accelerates the conversion of the organic waste, so that the oil and gas production process is efficient and fast. Through the synergistic effect of the above-mentioned characteristics, the oil and gas production device 100 of the present application can significantly improve the yield and quality of the oil and gas, reduce the energy consumption, effectively utilize the organic waste, and has high economic benefit and environmental protection value.

The isolation block 13 near the anode 21 of the electrode assembly 2 is made of water-permeable and mud-resistant material, which is made of water-permeable coated sand material, which can not only permeate water but also block mud, preventing the pollution of the electrode. It can be understood that the electrolytic cavity containing the cathode 22 of the electrode assembly 2 is provided with a gas outlet 12 for the output of oil and gas.

[0046] In an embodiment of the present application, the material of the anode 21 is sponge platinum, and the material of the cathode 22 is iron.

[0047] In the embodiment, it should be noted that the anode 21 adopts a plate structure to increase the reaction area. When sponge platinum is used as the anode 21, the sponge structure significantly increases the effective reaction area of the electrode, and improves the current efficiency and reaction rate. When iron is used as the cathode 22, the reduction reaction can be promoted. Figure 1It can be understood that the cathode 22 adopts a layered structure, and multiple iron plates are stacked, and gaps are left between adjacent layers for the liquid to pass through. At the same time, since the cathode 22 is made of iron material, it can also play a role of catalyst, and under the action of ultrasonic cavitation, carbon monoxide and hydrogen are further reacted to obtain alkanes and alkenes.

It can be understood that the type of the storage member 4 includes but is not limited to an atmospheric gas storage tank, a high-pressure gas cylinder, etc. The gas pipe 41 is a special gas pipe 41 for coal gas.

[0055] It should be noted that the control box (not shown in the figure) as a central control unit, can automatically adjust the voltage and current of the electrode assembly 2, the power frequency of the ultrasonic assembly 3, the opening and closing state of the pressure valve; the control box is built-in microprocessor or PLC controller, receiving signals from pressure sensor, temperature sensor, liquid level sensor and other sensors; according to the preset program, output control signal to electrode assembly 2, ultrasonic assembly 3, pressure valve and other executive components, realize the automation control to the whole reaction process.

The control box is connected with electrode assembly 2, ultrasonic assembly 3 and pressure valve through cable; by using standard industrial interface, to ensure stable and reliable signal transmission. It can be understood that the inner wall of one end of the cylinder 1 close to the gas inlet 12 is provided with a pressure valve, which can be connected with the cylinder 1 by flange connection, thread connection, welding and the like.

[0056] The present application also provides a process method for producing oil and gas in an oil and gas production device, wherein the method comprises the following steps:

[0057] The organic waste and clean water are added into the cylinder to obtain an organic mixture;

[0058] The organic mixture is electrified to obtain oxygen and hydrogen;

[0059] The ultrasonic assembly performs cavitation and oxidation on the organic mixture to obtain carbon monoxide;

[0060] The carbon monoxide and the hydrogen are reacted by Fischer-Tropsch synthesis to obtain hydrocarbon compounds.

[0061] In this embodiment, it can be understood that this step comprises S10-S40:

[0062] Step S10, the organic waste and clean water are added into the cylinder to obtain an organic mixture. It can be understood that the organic waste refers to plastic products in living areas, straw in farmland, grass, branches and leaves of trees, and woodworking organic waste, etc., which is not limited here. The organic mixture refers to the solid-liquid mixture formed after the organic waste is mixed with clean water, which is used as the reaction raw material. The clean water is used as the reaction medium to provide water molecules required for electrolysis reaction, that is, the organic waste is wrapped by clean water. It should be noted that the organic mixture is electrified in step S20. Figure 1In one embodiment, the oil and gas production device further comprises a hopper and a feeding pipe through which the organic waste is delivered to the feeding port of the barrel. Before being delivered to the hopper, the organic waste can be crushed by a crushing device so that the organic waste can be delivered to the barrel, and a mechanical conveying device can be provided to convey the organic waste to the hopper. The hopper can be installed on a support or a platform so that the organic waste can be delivered to the barrel through the feeding pipe. In combination with Figure 2 and Figure 3 In another embodiment, the barrel comprises a cover and a body, and the body is provided with an opening, and the cover covers the opening. It can be understood that the opening is actually the feeding port. Before the organic waste and the clean water are delivered to the barrel through the feeding port, the cover is opened, and the cathode of the electrode assembly and one of the isolation blocks in the barrel are taken out, so that the barrel is filled with the organic waste and the clean water. The cathode of the electrode assembly, one of the isolation blocks, and the cover are reinstalled in the barrel. The cover is provided with a gas delivery hole, which is actually a gas delivery port, and the gas delivery port is connected to the storage member through a special gas pipe.

[0063] In step S20, the organic mixture is electrified to obtain oxygen and hydrogen. It can be understood that electrification means that a direct current voltage is applied to the anode and the cathode of the electrode assembly to form an electric field. Oxygen is used for subsequent oxidation reaction to oxidize the organic waste; hydrogen is used for subsequent Fischer-Tropsch synthesis reaction to react with carbon monoxide to generate hydrocarbons. The electrode assembly refers to an electrochemical system composed of an anode and a cathode, wherein the anode is preferably a sponge platinum electrode for electrolyzing water to generate oxygen; the cathode is a ferrodisc electrode for electrolyzing water to generate hydrogen, and the cathode also has a catalytic effect to promote the synthesis of alkanes and alkenes from carbon monoxide and hydrogen. Here, the anode and the cathode are arranged at opposite ends of the barrel, and the cathode of the electrode assembly is arranged above the barrel compared to the anode of the electrode assembly. It should be noted that the electrode assembly is electrified and started when the clean water fills the entire barrel. The anode of the electrode assembly electrolyzes water to generate oxygen, and the chemical equation is: The cathode of the electrode assembly electrolyzes water to generate hydrogen, and the chemical equation is: In this way, oxygen and hydrogen can be generated inside the device without external gas supply, which simplifies the system structure and reduces the cost. During the electrolysis process, the gases in the two electrolysis cavities enter the reaction area through the two isolation blocks.

[0064] Step S30, the ultrasonic assembly cavitation and oxidation of the organic mixture, to obtain carbon monoxide. It can be understood that the ultrasonic assembly refers to a system composed of multiple tubular or rod-shaped ultrasonic transducers for generating cavitation, forming a local high temperature and high pressure supercritical microenvironment, strengthening the oxidation reaction and promoting the gas synthesis reaction. It should be noted that after the ultrasonic assembly is started, it performs cavitation on the organic waste in the cylinder body, and through the high-frequency vibration of the ultrasonic wave, micro-bubbles are generated in the liquid. These bubbles expand rapidly and collapse violently, forming a local high temperature and high pressure environment, i.e. a local critical environment, thereby cracking the macromolecular organic matter in the organic waste into small molecular substances and promoting the oxidation reaction; secondly, under the extreme conditions generated by cavitation, the organic matter in the organic waste further reacts with the active oxygen species (such as hydroxyl radicals, oxygen, etc.) generated in the electrolysis of clean water to generate carbon monoxide and other gas products.

[0065] Step S40, the carbon monoxide and the hydrogen gas through Fischer-Tropsch synthesis reaction to obtain hydrocarbon compounds. It can be understood that the hydrocarbon compounds refer to oil and gas such as alkanes and alkenes. The iron plate electrode as a cathode not only promotes the reduction reaction of clean water to generate hydrogen gas during electrolysis, but also has good catalytic activity, can further activate hydrogen molecules, and enhance their reduction capacity, providing a high-activity hydrogen source for subsequent reactions. It should be noted that under the synergistic promotion of ultrasonic cavitation and iron plate electrode catalysis, carbon monoxide and hydrogen gas undergo Fischer-Tropsch synthesis reaction to generate mixed gas mainly composed of alkanes and alkenes. These gases are important components of clean fuels and are high-value oil and gas.

[0066] It should be noted that the method steps ensure that the cylinder body maintains sufficient reaction materials and liquid level by adding organic waste and water into the cylinder body, which can maintain the electrolysis reaction and ultrasonic cavitation; secondly, under the power-on state, the electrode assembly starts to work, the anode electrolyzes water to generate oxygen, and the cathode iron plate group electrolyzes water to generate hydrogen, while the ultrasonic rod generates cavitation to form a local supercritical microenvironment, strengthen the oxidation degradation of organic matter in the organic waste, and generate carbon monoxide and other intermediate products. These gases are further synthesized into high-value oil and gas products such as alkanes and alkenes under the catalysis of the iron plate group; finally, when the reaction proceeds to the set time or the gas yield reaches the expected value, the oil and gas device completes a working cycle, at which time the feeding and power-on are stopped, the oil and gas products in the storage member are collected, and the residue is discharged, preparing for the next cycle, thereby realizing the resource conversion of organic waste and the efficient production of oil and gas.

[0067] In an embodiment of the present application, the step of obtaining hydrocarbon compounds by Fischer-Tropsch synthesis reaction of carbon monoxide and hydrogen gas further comprises:

[0068] The hydrocarbon compounds are transported to the storage member through the cylinder body.

[0069] The cylinder is subjected to pressure relief treatment.

[0070] In this embodiment, this step includes S50-S60:

[0071] The step includes S50, and the hydrocarbon compound is transported to a storage through the cylinder. It can be understood that the storage refers to a container or device for collecting and temporarily storing reaction gas, which is located outside the cylinder and connected to the cylinder through a gas pipe. The storage can be an oil and gas tank, a gas tank, etc., which has the characteristics of pressure resistance and good sealing, and is used for safely storing the gas products generated in the reaction, such as alkanes, alkenes, etc. high value-added oil and gas new energy. It should be noted that the generated oil and gas products are discharged through the gas outlet at the top of the cylinder, and the oil and gas is introduced into the storage through the gas pipe for centralized collection, avoiding the escape of oil and gas and facilitating subsequent use; finally, the storage temporarily stores and buffers the oil and gas products, stabilizes the oil and gas output pressure, ensures the safety and continuity of the subsequent processing or utilization process, and thus realizes the resource utilization of waste and efficient recovery of clean energy.

[0072] The step includes S60, and the cylinder is subjected to pressure relief treatment. It can be understood that the oil and gas device includes a pressure valve, which is arranged in the cylinder and close to the gas outlet. The pressure valve is used to slowly release the gas accumulated in the cylinder to a safe area, balance the pressure inside and outside the cylinder, and prevent equipment damage or operation risk caused by excessive internal pressure; during the pressure relief process, it is necessary to ensure that there is no open flame, no high temperature source, and good ventilation, so as to avoid the accumulation of flammable gas and cause explosion or poisoning accident; after the pressure relief is completed, the cylinder can be safely opened for slag discharge or feeding operation, so as to protect the safety of personnel and the integrity of equipment, and prepare for the next round of reaction. It should be noted that after this step is completed, the entire power supply and gas outlet are closed, the waste slag, residual liquid and flushing liquid are discharged from the cylinder, and preparation for the next round of reaction is made.

[0073] The above only describes the exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
