Description

Technical Field

[0001] The invention relates to the technical field of gas production, in particular to a light hydrocarbon gas generator. Background Art

[0002] Pentane is a byproduct of C5 processing, used as a low-boiling point solvent, foaming agent in the plastic industry, and used together with 2-methylbutane as automobile and aircraft fuel, to make artificial ice, anesthetics, and to synthesize amyl alcohol and isopentane. It can be obtained from the catalytic cracking and thermal decomposition of natural gas or petroleum.

[0003] However, due to different degrees of refining, pentane often contains isomers of C5 hydrocarbons, hydrocarbons with similar boiling points such as methylcyclopentane, as well as impurities such as unsaturated compounds, water, and sulfur-containing compounds. In the fuel production process, pentane mixed oil often needs to undergo complex processes such as purification and re-refining. The production benefits are far less than the investment, resulting in the waste of pentane mixed oil and the increase of fuel production input costs, which limits the feasibility of light hydrocarbon fuel production and does not conform to the environmentally friendly production concept of recycling and reuse.

[0023] 1. The light hydrocarbon gas generator in this scheme has a production reaction in which pentane mixed oil is input into the oil chamber of the generator barrel through a feed pipe. After the oil has submerged the oil chamber and the honeycomb fluidized bed, the air is connected to the external high-pressure air through an air intake pipe. When the air enters the oil chamber through the air intake pipe and mixes with the oil, the air contacts and mixes with the oil due to the injection pressure relationship to produce a jet. The bubbles that appear will also mix with the volatile substances in the pentane. As the gas rises, the bubbles carry away the volatile substances in the oil, and are ejected through the honeycomb injection holes on the surface of the honeycomb fluidized bed and discharged into the compressed air chamber to produce a gas-liquid mixed natural gas. Compared with the complicated recycling process of traditional pentane purification and refining, this light hydrocarbon gas generator prepares light hydrocarbon gas through pure physical reaction, reuses pentane, a by-product of gas production, reduces production costs and recycling preparation costs, improves the practicability of the generator, and facilitates promotion.

[0024] 2. The light hydrocarbon gas generator in this scheme, taking into account the flammable, explosive and active chemical properties of pentane, has a closed cavity in the generator cylinder where gas and liquid are separated, and the feed pipe, drain pipe, outlet pipe and other pipes connected to the external environment are all provided with partition blades and one-way flow channel structures. This prevents oil and gas from contaminating the oil and gas sources through the pipelines, while ensuring the stability of the gas and liquid reaction in the generator cylinder. In order to ensure the stability of normal temperature and pressure in the physical reaction cavity, the air and oil discharge pipelines are filtered through the strip gas grooves on the surface of the pipe plug and the plug shaft respectively to avoid leakage of excess residual oil and gas, thereby ensuring the stability of the light hydrocarbon gas generator.

[0025] 3.

DETAILED DESCRIPTION

[0034] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0035] Combination Figure 1-Figure 7 The present invention discloses a light hydrocarbon gas generator, comprising a left cylinder 1, a combined cylinder 3 and a right cylinder 4;

[0036] The upper end of the left cylinder 1 is provided with a feed pipe 5, an air inlet pipe 7 and an air outlet pipe 6 from left to right in sequence, and a honeycomb fluidized bed 8 is transversely provided at the lower end of the inner side of the left cylinder 1. The honeycomb fluidized bed 8 separates the left cylinder 1 into a compressed air chamber 15 and an oil accumulation chamber 14. The lower ends of the left cylinder 1 and the right cylinder 4 are both welded with supporting legs 9. The volume space ratio of the oil accumulation chamber 14 to the compressed air chamber 15 is one to two, and the compressed air chamber 15 is an airtight structure;

[0037] Example 1: Figure 1 As shown, after the light hydrocarbon gas generator is lifted and placed at the work site, the feed pipe 5 is connected to the pentane mixed oil source through a hose, the gas outlet pipe 6 is connected to the gas collection tank or the gas supply pipeline to provide gas through the light hydrocarbon gas generator, the drain pipe 11 is connected to the oil collection tank or other residue collection structure, and the control interface pipe 10 is connected to the production equipment pipeline opening and closing valve body. The valve body is controlled to close and open by the production equipment PLC system to confirm the working status of the gas generator, and the installation preparation work is completed.

[0038] A reaction bed surface 33 is formed on the upper surface of the honeycomb fluidized bed 8, and honeycomb injection holes 12 are evenly distributed on the surface of the honeycomb fluidized bed 8. Flanges 32 are protruding from the four corners of the honeycomb fluidized bed 8, and fluidized bed brackets 13 are welded to the lower ends of the flanges 32. The left end fluidized bed bracket 13 is fixedly connected to the inner wall of the left cylinder 1. The honeycomb injection port 12 on the surface of the honeycomb fluidized bed 8 is a conical cut structure, and the hole wall of the honeycomb injection hole 12 is smooth.

[0039] The lower end of the feed pipe 5 passes through the honeycomb fluidized bed 8 and communicates with the oil accumulation chamber 14. The upper end of the feed pipe 5 is formed with a feed port 16. The lower end of the feed pipe 5 is slotted with a narrow slot 17. The narrow slot 17 and the feed pipe 5 are separated by a partition leaf 18. A transmission flow valve port pipe 19 is penetrated in the middle of the partition leaf 18. The transmission flow valve port pipe 19 communicates with the feed pipe 5 and the narrow slot 17. The feed pipe 5 is of the same length as the air intake pipe 7. The lower end of the feed pipe 5 is located at the bottom of the oil accumulation chamber 14. The transmission flow valve port pipe 19 is a one-way pipeline structure.

[0040] Embodiment 2: After the above embodiment, pentane mixed oil (hereinafter referred to as oil) enters the generator oil accumulation chamber 14 along the feed pipe 5. When the oil passes through the feed pipe 5, the oil flows downstream along the transmission flow valve port pipe 19 and the narrow groove 17. After the oil is compressed by the pipeline, the volatile substances in the oil are mixed in the oil and maintain a relative mixing ratio with the oil pentane substance. Since the transmission flow valve port pipe 19 is a one-way pipeline, the backflow of the oil is avoided to affect the reaction. The oil delivery process stops until the oil level in the oil accumulation chamber 14 submerges the honeycomb fluidized bed 8.

[0041] Embodiment 3: After the above embodiment is completed, the air source is supplied and air is input into the oil accumulation chamber 14 through the air intake pipe 7. Since the air intake pipe 7 is equal in length to the feed pipe 5 and the bottom openings are both located at the bottom of the oil accumulation chamber 14, the air rushed into the oil accumulation chamber 14 will break through the oil and rise due to the relationship between the density of gas and liquid. The rushed air will be strongly mixed with the oil and generate bubbles. Due to the effect of pressure, the bubbles will be repeatedly broken and aggregated before leaving the oil. The bubbles are mixed with the volatile substances in the oil to form a relatively soluble combustion gas, which breaks through the oil surface and rises to the compressed air chamber 15 through the honeycomb injection holes 12 on the surface of the honeycomb fluidized bed 8.

[0042] The lower end of the gas outlet pipe 6 is interconnected with the upper end of the cavity wall of the compressed gas cavity 15, and an exhaust port 20 is formed at the upper end of the gas outlet pipe 6. A wide-mouth groove 23 is provided at the lower end of the gas outlet pipe 6. A gas passage 21 is provided between the exhaust port 20 and the wide-mouth groove 23. A plurality of sleeve rings 22 are connected to the outer surface of the gas passage 21. A pipe plug 24 is inserted at the connection between the gas passage 21 and the wide-mouth groove 23. The surface of the pipe plug 24 is provided with a plurality of strip-shaped gas grooves distributed at equal intervals in an annular shape. The strip-shaped gas grooves in the pipe plug 24 are interconnected with the wide-mouth groove 23. The sleeve ring 22 is a pressure-resistant hard rubber ring. The sleeve ring 22 is provided at the gap between the gas outlet pipe 6 and the gas passage 21. The pressure in the space at the gap between the gas outlet pipe 6 and the gas passage 21 is atmospheric pressure.

[0043] Embodiment 4: After the gas fills the compressed gas cavity 15, the gas is discharged through the multiple gas outlet pipes 6 distributed at the upper end of the gas generator cylinder. During the process, the gas will converge into the tube body along the wide-mouth groove 23 at the lower end of the gas outlet pipe 6, and the wet gas with low solubility in the gas mixed with oil will be filtered through the strip gas grooves distributed on the surface of the pipe plug 24. At the same time, the gap between the gas channel 21 and the gas outlet pipe 6 and the setting of the sleeve ring 22 ensure the stability of the air pressure around the pipeline when the gas passes through, so as to avoid gas leakage.

[0044] The combined cylinder 3 is provided through the right end of the left cylinder 1, and a flange 2 is fixedly connected between the combined cylinder 3 and the left cylinder 1. The combined cylinder 3 is composed of three sections of cylinders of equal specifications combined by the flange 2, and an air outlet pipe 6 and an air inlet pipe 7 are provided through the upper end of each section of the cylinder;

[0045] The right cylinder 4 is fixed to the right end of the combined cylinder 3 through the flange 2. The right cylinder 4 is provided with an air outlet pipe 6, an air inlet pipe 7 and a control interface pipe 10 from left to right. A sewage pipe 11 is plugged into the right lower end of the right cylinder 4. The sewage pipe 11 is communicated with the oil accumulation chamber 14. The control interface pipe 10 is an air source pipeline. The lower end of the control interface pipe 10 passes through the honeycomb fluidized bed 8 and communicates with the oil accumulation chamber 14.

[0046] The upper and lower ends of the sewage pipe 11 are respectively opened with an inner pipe interface 31 and an interface disk 25, a pair of latches 26 are inserted on the left and right sides of the interface disk 25, a compression chamber 28 is grooved in the middle of the sewage pipe 11, a plug shaft 27 is embedded in the middle of the compression chamber 28, a shaft disk 29 is sleeved on the upper end of the plug shaft 27, a push rod 30 is inserted in the middle of the upper end of the shaft disk 29, a plurality of compression springs are distributed in an annular manner at the connection between the plug shaft 27 and the shaft disk 29, the plug shaft 27 is slidably connected to the inner wall of the sewage pipe 11, and the shaft disk 29 is consistent in size with the pipe opening of the sewage pipe 11.

[0047] Embodiment 5: After the gas preparation is completed, an external suction pump body is connected to one end of the interface disk 25 of the sewage pipe 11 to make the plug shaft 27 and the shaft disk 29 move as pistons along the compression chamber 28 and the sewage pipe 11 through the action of the suction pressure. The residual residue in the oil will enter the compression chamber 28 along the inner pipe interface 31 at the other end of the sewage pipe 11. As the piston moves, the residue is discharged through the sewage pipe 11 one after another, and the staff collects and processes it.
