Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to an energy-saving and environmentally friendly distillation tower for asphalt production and processing. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, mostly existing in the form of tar or asphalt, with a black surface, and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material, mainly divided into three types: coal tar pitch, petroleum asphalt, and natural asphalt. It is used in industries such as coatings, plastics, and rubber, as well as in road paving.

[0003] A distillation column is a tower-type gas-liquid contact device used for distillation. It utilizes the fact that the components in a mixture have different volatility, i.e., different vapor pressures at the same temperature, to transfer lighter components (low-boiling substances) from the liquid phase to the gas phase, while heavier components (high-boiling substances) from the gas phase are transferred to the liquid phase, thus achieving separation. It is commonly used in asphalt production.

[0004] Because the spraying components used for spraying liquid phase components inside the distillation column are fixed, the spraying range they can reach is small, which means that some asphalt vapor cannot be sprayed, thus affecting the reaction rate. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving and environmentally friendly distillation tower for asphalt production and processing, which has the effect of improving the reaction rate.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: It includes a tower body, an inlet pipe connected to the bottom of the tower body, and a first extraction pipe connected to the bottom of the tower body. An air inlet pipe is connected to the tower body, a filter screen is installed inside the tower body, and an air outlet pipe is connected to the top of the tower body. A extraction pump is installed on the first extraction pipe, and an L-shaped second extraction pipe is connected to the top of the first extraction pipe. The second extraction pipe passes through the top of the tower body, and a spray pipe is rotatably installed at the bottom of the second extraction pipe in a horizontal direction. Several spray heads are installed on the spray pipe, and a rotating mechanism for driving the spray pipe to rotate is installed inside the tower body.

[0007] A further feature of this invention is that the rotating mechanism includes a rotating shaft rotatably mounted on the tower body in a vertical direction and a drive motor mounted at the bottom of the tower body for driving the rotating shaft. The top end of the rotating shaft is fixedly connected to the spray pipe, and the rotating shaft movably passes through the filter screen.

[0008] A further feature of this invention is that a plurality of scrapers are evenly arranged on the rotating shaft along the horizontal direction, and the bottom of the scrapers can be movably attached to the filter screen.

[0009] A further feature of this invention is that the outer wall of the scraper is provided with an elastic adsorption layer.

[0010] A further feature of this invention is that several sets of stirring blades are evenly arranged at the bottom of the rotating shaft.

[0011] A further feature of this invention is that the stirring blades are arranged vertically, and there is a set distance between the bottom end of the stirring blades and the inner wall of the tower body.

[0012] A further feature of this invention is that a stirring rod is uniformly provided at the bottom end of the stirring blade in the vertical direction, and the bottom end of the stirring rod can be movably attached to the inner wall of the tower body.

[0013] A further feature of this invention is that a heater is provided on the air intake pipe.

[0015] A further feature of this invention is that the number of stirring blades is 6.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting up spray pipes and rotating mechanisms, during operation, liquid feed is first introduced into the tower through the inlet pipe, and asphalt vapor is introduced into the tower through the air inlet pipe. Then, the pump and rotating mechanism are turned on, and the liquid feed enters the spray pipe through the first and second pumping pipes. As the rotating mechanism drives the spray pipe to rotate, the liquid feed is sprayed down from the spray head. The liquid feed falls under the action of gravity, and after passing through the filter screen, it comes into contact with the upward floating asphalt vapor for mass transfer. Finally, the distilled gas is discharged from the outlet pipe. By setting up spray pipes and rotating mechanisms, the spray area of ​​the spray head is greatly increased, thereby increasing the contact area between the liquid feed and the asphalt vapor, thus achieving the purpose of improving the reaction rate.

[0018] 2. By setting up scrapers and elastic adsorption layers, when the liquid is sprayed through the filter screen, the scrapers push the liquid to accelerate the rate at which the liquid passes through the filter screen, thereby improving the reaction efficiency; at the same time, the elastic adsorption layer on the scrapers can adsorb larger particles that remain on the filter screen, preventing the filter screen from being blocked and affecting the efficiency of the liquid passing through the filter screen.

[0024] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] This utility model provides an energy-saving and environmentally friendly distillation tower for asphalt production and processing, such as... Figures 1 to 3 As shown, the tower includes a tower body 1, an inlet pipe 2 connected to the bottom of the tower body 1, and a first extraction pipe 3 connected to the bottom of the tower body 1. An air inlet pipe 4 is connected to the tower body 1. A filter screen 5 is installed inside the tower body 1. An air outlet pipe 6 is connected to the top of the tower body 1. A extraction pump 7 is installed on the first extraction pipe 3. An L-shaped second extraction pipe 8 is connected to the top of the first extraction pipe 3. The second extraction pipe 8 passes through the top of the tower body 1. A spray pipe 9 is rotatably installed at the bottom of the second extraction pipe 8 in a horizontal direction. Several spray heads 10 are installed on the spray pipe 9. A rotating mechanism 11 for driving the spray pipe 9 to rotate is installed inside the tower body 1.

[0026] Furthermore, the rotating mechanism 11 includes a rotating shaft 11a that is rotatably mounted on the tower body 1 in a vertical direction and a drive motor 11b located at the bottom of the tower body 1 for driving the rotating shaft 11a. The top end of the rotating shaft 11a is fixedly connected to the spray pipe 9, and the rotating shaft 11a moves through the filter screen 5.

[0027] Furthermore, several sets of scrapers 12 are evenly arranged on the rotating shaft 11a along the horizontal direction, and the bottom of the scraper 12 can be movably attached to the filter screen 5.

[0028] Furthermore, the outer wall of the scraper 12 is provided with an elastic adsorption layer 13.

[0029] Furthermore, several sets of stirring blades 14 are evenly arranged at the bottom of the rotating shaft 11a.

[0030] Furthermore, the stirring blade 14 is arranged vertically, and there is a set distance between the bottom end of the stirring blade 14 and the inner wall of the tower body 1.

[0031] Furthermore, stirring rods 15 are evenly arranged vertically at the bottom end of the stirring blade 14, and the bottom end of the stirring rods 15 can be movably attached to the inner wall of the tower body 1.

[0032] Furthermore, a heater 16 is provided on the air intake pipe 4.

[0033] Furthermore, the number of scrapers 12 is 6.

[0034] Furthermore, the number of stirring blades 14 is 6.

[0035] When using the distillation column, the feed liquid is first introduced into the column body 1 through the liquid inlet pipe 2, and asphalt vapor is introduced into the column body 1 through the gas inlet pipe 4. Then, the liquid pump 7 and drive motor 11b are turned on, and the feed liquid enters the spray pipe 9 through the first liquid extraction pipe 3 and the second liquid extraction pipe 8. During the rotation of the spray pipe 9 driven by the rotating shaft 11a, the feed liquid is sprayed down from the spray head 10. The feed liquid falls under the action of gravity, and after passing through the filter screen 5, it comes into contact with the upward floating asphalt vapor for mass transfer. Finally, the distilled gas is discharged from the gas outlet pipe 6. (It should be noted that one-way valves are installed on the liquid inlet pipe 2, the gas inlet pipe 4, the first liquid extraction pipe 3, and the gas outlet pipe 6 to ensure the flow direction of gas and liquid. Since the one-way valve is existing technology, it will not be described in detail and will not affect the actual scope of the technology protected by this application.) By setting up the spray pipe 9 and the rotating mechanism 11, the spraying area of ​​the spray head 10 is greatly increased, thereby increasing the contact area between the feed liquid and the asphalt vapor, and achieving the purpose of improving the reaction rate.

[0036] By setting up scraper 12 and elastic adsorption layer 13, when the liquid is sprayed through the filter screen 5, the scraper 12 pushes the liquid to accelerate the rate at which the liquid passes through the filter screen 5, thereby improving the reaction efficiency. At the same time, the elastic adsorption layer 13 on the scraper 12 can adsorb larger particles that remain on the filter screen 5 onto the scraper 12, avoiding clogging of the filter screen 5 and affecting the efficiency of the liquid passing through the filter screen 5.

[0037] By setting up stirring blades 14, the rotating shaft 11a drives the spray pipe 9 to rotate while also driving the scraper 12 and stirring blades 14 to rotate. The stirring blades 14 stir the liquid material, so that the liquid material can be evenly distributed, which is beneficial for the pump 7 to evenly draw the liquid material for spraying, thereby ensuring that the liquid material can come into contact with the asphalt vapor.

[0038] By setting the stirring blade 14 vertically and maintaining a certain distance between the stirring blade 14 and the bottom of the tower body 1, the liquid material is prevented from adhering to the stirring blade 14, thus affecting the extraction and spraying of the liquid material.

[0039] By setting up heater 16 to heat the asphalt vapor, it is beneficial to the distillation of the asphalt vapor in tower body 1.

[0040] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
