Description

Technical Field

[0001] This utility model relates to the field of waste gas purifier technology, and in particular to a waste gas purification device for hydrogen-oil-gas separation. Background Technology

[0002] Exhaust gas purifiers, also known as "exhaust gas processors" or "exhaust gas treatment equipment," are devices specifically designed to treat exhaust gases generated during industrial production, vehicle emissions, or other processes to reduce their environmental pollution. Exhaust gas purifiers remove or reduce harmful substances in exhaust gases through physical, chemical, or biological processes, thereby ensuring that exhaust emissions meet national or regional environmental standards. These harmful substances may include particulate matter, harmful gases (such as sulfur dioxide and nitrogen oxides), and volatile organic compounds.

[0003] Although existing exhaust gas purifiers can purify exhaust gas simply, they can only filter the exhaust gas and cannot purify the hydrogen in the exhaust gas. This not only results in poor filtration efficiency and air pollution, but also prevents the recovery and reuse of hydrogen in the exhaust gas. Therefore, an exhaust gas purification device for hydrogen-oil-gas separation is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing exhaust gas purifiers, which can only filter exhaust gas but cannot purify hydrogen in the exhaust gas. These shortcomings include poor filtration efficiency, causing air pollution, and the inability to recycle and reuse hydrogen in the exhaust gas. Therefore, this invention proposes an exhaust gas purification device for hydrogen-oil-gas separation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste gas purification device for hydrogen-oil-gas separation includes a rectangular base plate, an oil-gas separation box disposed on the base plate, a hydrogen purification tank fixedly connected to the base plate, a filter box fixedly connected to the base plate, a first rectangular opening on one side of the oil-gas separation box, a first rectangular plate slidably connected to the first rectangular opening, a first filter screen fixedly connected to one side of the first rectangular plate, and the first filter screen slidably connected to the inner wall of the oil-gas separation box.

[0007] Preferably, an air inlet pipe is fixedly connected to one side of the oil-gas separator, an oil outlet pipe is fixedly connected to the bottom of the oil-gas separator, a first solenoid valve is installed on the oil outlet pipe, a first gas outlet pipe is fixedly connected to the top of the oil-gas separator, and one end of the first gas outlet pipe is fixedly connected to a hydrogen purification tank.

[0008] Preferably, a support plate is fixedly connected to the inner wall of the hydrogen purification tank. A circular hole is provided on the support plate, and a circular groove is provided at the circular hole. A limit ring is slidably connected in the circular groove. A palladium alloy separation tube is fixedly connected to the bottom of the limit ring and is slidably connected to the circular hole. A lifting ring is fixedly connected to the top of the limit ring.

[0009] Preferably, the top of the hydrogen purification tank is provided with a sealing groove, a top cover is slidably connected to the top of the hydrogen purification tank, a sealing ring is fixedly connected to the bottom of the top cover, the sealing ring is slidably connected to the sealing groove, a pressure boosting valve is installed on the support plate, a suction pipe is connected to one side of the pressure boosting valve, a second outlet pipe is connected to the top of the pressure boosting valve, the second outlet pipe passes through one side of the hydrogen purification tank, a connecting pipe is fixedly connected to one side of the hydrogen purification tank, one end of the connecting pipe is fixedly connected to the filter box, and a second solenoid valve is installed on the connecting pipe.

[0010] Preferably, the top of the filter box has a second rectangular opening, a second rectangular plate is slidably connected inside the second rectangular opening, a second filter screen is fixedly connected to one side of the second rectangular plate, limit grooves are opened on both sides of the filter box, the second filter screen is slidably connected to the limit grooves, and a third air outlet pipe is fixedly connected to one side of the filter box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. During use, this equipment can separate oil and gas through an oil-gas separator. Heavier oil flows out from the bottom of the oil-gas separator through the oil outlet pipe. The first solenoid valve controls the flow of oil from the oil outlet pipe. Lighter waste gas, after being initially filtered by the first filter screen, enters the hydrogen purification tank through the first gas outlet pipe. The palladium alloy separator in the hydrogen purification tank separates the hydrogen in the waste gas. The filter box further filters the hydrogen-purified waste gas, resulting in better filtration, avoiding air pollution, and enabling the recovery and reuse of hydrogen in the waste gas.

[0013] 2. When using this equipment, the sliding ring and circular groove allow the staff to open the top cover periodically and remove the palladium alloy separation tube for replacement via the lifting ring, ensuring separation efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-7 A waste gas purification device for hydrogen-oil-gas separation includes a rectangular base plate 1, an oil-gas separation box 2 disposed on the base plate 1, a hydrogen purification tank 3 fixedly connected to the base plate 1, and a filter box 4 fixedly connected to the base plate 1.

[0024] Furthermore, a first rectangular opening is provided on one side of the oil-gas separator 2, and a first rectangular plate 5 is slidably connected to the first rectangular opening. A first filter screen 6 is fixedly connected to one side of the first rectangular plate 5, and the first filter screen 6 is slidably connected to the inner wall of the oil-gas separator 2.

[0025] The first filter screen 6 performs preliminary filtration of oil and gas, removing larger impurities. The first rectangular plate 5 can be removed through the handle, making it convenient to replace and clean the first filter screen 6 at any time.

[0026] Furthermore, an air inlet pipe 7 is fixedly connected to one side of the oil-gas separator 2, an oil outlet pipe 8 is fixedly connected to the bottom of the oil-gas separator 2, a first solenoid valve is installed on the oil outlet pipe 8, and a first gas outlet pipe 9 is fixedly connected to the top of the oil-gas separator 2. One end of the first gas outlet pipe 9 is fixedly connected to the hydrogen purification tank 3.

[0027] In this process, oil and gas enter the oil-gas separator 2 through the first inlet pipe 7. Then, the heavier oil flows out from the bottom of the oil-gas separator 2 through the oil outlet pipe 8. The first solenoid valve controls the flow of oil from the oil outlet pipe 8, while the lighter waste gas enters the hydrogen purification tank 3 through the first outlet pipe 9.

[0028] Furthermore, a support plate 10 is fixedly connected to the inner wall of the hydrogen purification tank 3. A circular hole 11 is opened on the support plate 10, and a circular groove 12 is opened at the circular hole 11. A limit ring 13 is slidably connected in the circular groove 12. A palladium alloy separation tube 14 is fixedly connected to the bottom of the limit ring 13. The palladium alloy separation tube 14 is slidably connected to the circular hole 11. A lifting ring is fixedly connected to the top of the limit ring 13.

[0029] The palladium alloy separation tube 14 inside the hydrogen purification tank 3 separates the hydrogen in the waste gas. The hydrogen flows along the palladium alloy separation tube 14 to the support plate 10. The sliding ring and the circular groove 12 allow the staff to open the top cover 16 periodically and remove the palladium alloy separation tube 14 for replacement through the lifting ring, thus ensuring the efficiency of the separation.

[0030] Furthermore, a sealing groove 15 is provided on the top of the hydrogen purification tank 3, and a top cover 16 is slidably connected to the top of the hydrogen purification tank 3. A sealing ring is fixedly connected to the bottom of the top cover 16, and the sealing ring is slidably connected to the sealing groove 15. A pressure boosting valve 17 is installed on the support plate 10, and a suction pipe is connected to one side of the pressure boosting valve 17. A second outlet pipe 18 is connected to the top of the pressure boosting valve 17. The second outlet pipe 18 passes through one side of the hydrogen purification tank 3, and a connecting pipe 19 is fixedly connected to one side of the hydrogen purification tank 3. One end of the connecting pipe 19 is fixedly connected to the filter box 4, and a second solenoid valve 20 is installed on the connecting pipe 19.

[0031] The sealing groove 15 and the sealing groove 15 seal the hydrogen purification tank 3 to prevent hydrogen from escaping from the gap between the top cover 16 and the hydrogen purification tank 3. The pressure boosting valve 17 extracts hydrogen through the extraction pipe and then transports it to the container through the second outlet pipe 18 to facilitate the storage and transportation of hydrogen. The second solenoid valve 20 controls the waste gas to enter the filter box 4 from the hydrogen purification tank 3.

[0032] Furthermore, a second rectangular opening is provided on the top of the filter box 4, a second rectangular plate 21 is slidably connected inside the second rectangular opening, a second filter screen 22 is fixedly connected to one side of the second rectangular plate 21, a limiting groove 23 is provided on the inner walls of both sides of the filter box 4, the second filter screen 22 is slidably connected to the limiting groove 23, and a third air outlet pipe 24 is fixedly connected to one side of the filter box 4.

[0033] The limiting groove 23 limits the second filter screen 22, and the second filter screen 22 can be easily removed for cleaning and replacement at any time through the handle and the second rectangular plate 21. The second filter screen 22 performs a second, more detailed filtration on the exhaust gas after hydrogen purification to ensure that the exhaust gas will not pollute the air before being discharged through the third exhaust pipe 24.

[0034] The working principle of this utility model:

[0035] Oil and gas enter the oil-gas separator 2 through the first inlet pipe 7. The heavier oil then flows out from the bottom of the separator 2 through the outlet pipe 8. The first solenoid valve controls the flow of oil through the outlet pipe 8. The lighter exhaust gas, after preliminary filtration through the first filter screen 6, enters the hydrogen purification tank 3 through the first outlet pipe 9. The palladium alloy separator 14 in the hydrogen purification tank 3 separates the hydrogen from the exhaust gas. The hydrogen travels along the palladium alloy separator 14 to the top of the support plate 10, where the pressure booster valve 17 draws air. Hydrogen is extracted through a pipe and then transported to a container through a second outlet pipe 18 for convenient storage and transportation. A second solenoid valve 20 controls the waste gas to enter the filter box 4 from the hydrogen purification tank 3. A second filter screen 22 performs a second, more thorough filtration of the hydrogen-purified waste gas to ensure that the waste gas does not pollute the air before being discharged through a third outlet pipe 24. This new type of filtration has a better effect, avoids air pollution, and can recover and reuse the hydrogen in the waste gas.

[0036] The sliding of the sliding ring and the circular groove 12 allows the staff to open the top cover 16 periodically and remove the palladium alloy separation tube 14 for replacement via the lifting ring, ensuring separation efficiency.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
