Description

Technical Field

[0001] This invention relates to the field of gasoline distillation technology, specifically to an aviation gasoline distillation system that reduces solid waste emissions. Background Technology

[0002] Aviation gasoline distillation systems that reduce solid waste emissions are core environmental protection equipment in the field of aviation fuel production. Their core function is to optimize the distillation process and solid waste recycling mechanism.

[0003] The distillation system mainly involves the feedstock oil entering the distillation tower, where it undergoes multiple vaporization-condensation processes at set temperature and pressure to achieve component separation. The aviation gasoline fraction is purified and then output. The resulting solid waste is collected and classified by the separation module, the waste catalyst is recycled in the regeneration unit, and the residue is treated to render it harmless and then recovered as a resource.

[0004] However, the above-mentioned equipment has certain shortcomings in use. The heating tubes of the existing distillation system are mostly of a straight structure, with a small heating area and uneven heating. Local overheating of the raw material can easily lead to coking reaction, generating a large amount of coke residue-like solid waste. The solid waste discharge is large, the treatment cost is high, and it pollutes the environment. In view of this, we propose an aviation gasoline distillation system to reduce solid waste emissions.

This aviation gasoline distillation system, designed to reduce solid waste emissions, is equipped with a distillation unit to meet the needs of large-scale aviation gasoline production. This unit, in conjunction with a bottom heating device, uses spiral heating tubes to uniformly heat the raw material, causing it to rapidly vaporize and be transported to a parallel distillation tower via connecting pipes. The spiral heat-conducting tubes of the distillation heating device provide segmented heating, while an arc-shaped filter plate initially filters out heavy component impurities.

[0023] Please see Figures 1-7 The present invention provides a technical solution: An aviation gasoline distillation system for reducing solid waste emissions includes a heating cylinder 1.

[0024] In one embodiment of the present invention, a distillation assembly 2 is provided on the heating cylinder 1. The distillation assembly 2 includes a bottom heating device 21, which is fixedly installed at the bottom of the heating cylinder 1. A base 22 is fixedly installed at the bottom of the bottom heating device 21. A heating tube 23 is fixedly installed at the heating end of the bottom heating device 21. One end of a connecting pipe 24 is fixedly installed on the heating cylinder 1, and a distillation column 25 is fixedly installed at the other end of the connecting pipe 24. A distillation heating device 26 is fixedly installed on the distillation column 25. A drain pipe 27 is fixedly installed at the bottom of the distillation column 25. A heat-conducting pipe 28 is fixedly installed at the heating end of the distillation heating device 26. An arc-shaped filter plate 29 and a spiral baffle plate 210 are fixedly installed inside the distillation column 25. One end of an inclined tube 211 is fixedly installed at the top of the distillation column 25. A condenser 212 is fixedly installed on the inclined tube 211, and the other end of the inclined tube 211 is fixed... The heating cylinder 1 includes a cylinder body 11, a collection cylinder 213, a feeding cylinder 12 fixedly installed at the top of the cylinder body 11, a cover plate 13 snapped onto the feeding cylinder 12, a discharge pipe 14 fixedly installed at the bottom of the cylinder body 11, a drain pipe 27 and a valve 31 fixedly installed on the discharge pipe 14, a temperature sensor 32 fixedly installed on the heating cylinder 1 and the distillation column 25, a heating tube 23 and a heat conduction tube 28 are designed in a spiral state, the heating tube 23 is set inside the heating cylinder 1, the heat conduction tube 28 is set inside the distillation column 25 and below the arc-shaped filter plate 29, a spiral baffle 210 is set above the arc-shaped filter plate 29, the internal space of the heating cylinder 1 is connected to the internal space of the distillation column 25 through a connecting pipe 24, the internal space of the distillation column 25 is connected to the internal space of the collection cylinder 213 through an inclined pipe 211, and the connection point between the connecting pipe 24 and the distillation column 25 is set below the arc-shaped filter plate 29.

[0025] In this embodiment, before production, the cover plate 13 on the feeding cylinder 12 is opened, and aviation gasoline raw material is injected into the cylinder body 11. The cover plate 13 is then closed. The temperature parameters of the heating cylinder 1 and the distillation column 25 are preset by the temperature sensor 32 to ensure distillation accuracy. The bottom heating device 21 is then started, and its base 22 ensures stable operation. The spiral heating tube 23 evenly releases heat inside the heating cylinder 1, quickly heating the raw material to a vaporized state. The vaporized raw material is then transported to the distillation column 25 via the connecting pipe 24. The distillation heating device 26 is then started, providing segmented heating through the spiral heat conduction tube 28 to maintain the temperature in different areas of the column. The gradient meets the requirements of distillation separation. During the vapor phase rise, it first passes through the arc-shaped filter plate 29 for preliminary filtration of heavy component impurities. The heavy components slide to the bottom of the column under the action of gravity. Then, the vapor phase passes through the spiral baffle plate 210. Its spiral structure prolongs the residence time of the vapor phase and enhances the gas-liquid mass transfer effect, so that the light components and heavy components are completely separated. The qualified light component vapor phase is transported to the condenser 212 through the inclined tube 211. After being quickly condensed into liquid, it flows into the collection cylinder 213 for collection. The drain pipe 27 at the bottom of the distillation column 25 and the discharge pipe 14 of the heating cylinder 1 are used to centrally discharge a small amount of heavy component solid waste. The timing of discharge is controlled by the valve 31 to reduce solid waste pollution.

[0026] In one embodiment of the present invention, an auxiliary component 4 is provided on the distillation column 25. The auxiliary component 4 includes a bent conduit 41. One end of the bent conduit 41 is fixedly installed on the distillation column 25, and the other end of the bent conduit 41 is fixedly installed on an installation cylinder 42. A servo motor 44 is fixedly installed on the installation cylinder 42, and a fan blade 45 is fixedly installed at the output end of the servo motor 44. An inclined guide plate 46 is fixedly installed inside the distillation column 25, and a thick filter plate 43 is fixedly installed inside the bent conduit 41. A protective eaves 47 is fixedly installed on the inner wall of the distillation column 25. The fan blade 45 is disposed inside the installation cylinder 42. The internal space of the installation cylinder 42 is connected to the internal space of the distillation column 25 through the bent conduit 41. The bent conduit 41 is obliquely opposite the bottom of the spiral baffle 210 and the surface of the inclined guide plate 46. The inclined guide plate 46 is disposed at the bottom of the spiral baffle 210 and above the arc-shaped filter plate 29.

[0027] In this embodiment, during the distillation process, the servo motor 44 on the mounting cylinder 42 is started, driving the fan blade 45 to rotate and generate directional airflow. The airflow is blown through the bent conduit 41 to the bottom of the spiral baffle 210 and the surface of the inclined guide plate 46 inside the distillation column 25, accelerating the vapor phase circulation, avoiding local vapor phase stagnation that could lead to side reactions, and further reducing solid waste emissions. The thick filter plate 43 inside the bent conduit 41 intercepts fine solid waste particles carried in the airflow, preventing particles from entering the mounting cylinder 42 and interfering with the rotation of the fan blade 45, thus extending the service life of the equipment. The protective eaves 47 on the inner wall of the distillation column 25 prevent the vapor phase from entering the heating cylinder 1 in reverse, avoiding material interference between different processes and ensuring distillation purity. The inclined guide plate 46 guides the directional flow of the vapor phase, allowing the vapor phase to pass evenly through the spiral baffle 210, thereby improving mass transfer efficiency.

[0028] In one embodiment of the present invention, a stirring assembly 5 is provided on the heating cylinder 1. The stirring assembly 5 includes a mounting plate 51, which is fixedly installed on the bottom side of the distillation column 25.

The straight rod 56 and multiple sets of arc-shaped fan plates 57 are located inside the heating cylinder 1, and multiple sets of arc-shaped fan plates 57 are located inside the heating pipe 23.

[0029] In this embodiment, during the raw material heating stage, the power motor 55 on the circular plate 54 starts, driving the straight rod 56 to drive multiple sets of arc-shaped fan-shaped plates 57 to rotate between the heating tubes 23 inside the heating cylinder 1, continuously stirring the raw material to avoid local overheating and coking, while ensuring uniform heating of the raw material and improving vaporization efficiency. Inside the distillation column 25, the bottom motor 52 on the mounting plate 51 drives the turbulence paddle 53 to rotate obliquely below the heat conduction tube 28, promoting full contact between vapor and liquid and enhancing mass and heat transfer effects. The multiple sets of stirring components 5 are adapted to the parallel layout of multiple columns, and the stirring rhythm of each column is coordinated, further improving the raw material conversion rate and reducing the waste of unreacted raw materials.
