DETAILED DESCRIPTION

[0034] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] For example, after the first pyrolysis of waste plastics and other high-molecular materials, the oil produced by pyrolysis has a high viscosity, so it is called crude oil. This fuel oil is difficult to be used normally and smoothly because some macromolecules in this crude oil are not fully cracked and are distilled out with the oil and gas. Therefore, a process that can further crack the macromolecules should be designed to deeply crack the macromolecules, thereby reducing the viscosity of the oil.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the purpose of this embodiment is to provide a semi-continuous crude oil distillation device combined with an energy ball, comprising a preheating body and a refining body connected to the preheating body, the refining body comprising a continuous reaction component 1 and a gas-slag filtering component 2 arranged in the continuous reaction component 1;

[0039] The continuous reaction assembly 1 includes a heating furnace 11 and a semi-continuous distillation kettle 12 located in the heating furnace 11. One end of the semi-continuous distillation kettle 12 is connected to a preheating body through an oil pipe 121. A plurality of energy balls 122 for heat transfer are arranged in the semi-continuous distillation kettle 12. A flue gas circulation structure is connected to the top of the semi-continuous distillation kettle 12, and the flue gas circulation structure is connected to the preheating body.

[0040] The gas-slag filtering assembly 2 comprises an oil ball screening structure 21 and a ball disturbance structure 22 which is transmission-connected to the oil ball screening structure 21. The oil ball screening structure 21 is located at one end of the semi-continuous distillation kettle 12 away from the oil pipe 121. The oil ball screening structure 21 is used to separate energy balls 122 in the oil. The energy balls 122 are spheres made of a heat-conducting medium. The ball disturbance structure 22 is located in the semi-continuous distillation kettle 12 and is slidingly connected to the inner wall of the semi-continuous distillation kettle 12 to drive the movement of the energy balls 122. The crude oil is introduced into the semi-continuous distillation kettle 12 through the oil pipe 121 by the preheating body. The oil ball screening structure 21 drives the ball disturbance structure 22 to move in the semi-continuous distillation kettle 12, and then drives the energy balls 122 to move through the ball disturbance structure 22, so that the heat is evenly transferred to the crude oil to ensure the full cracking of the macromolecular substances in the crude oil. In addition, the movement of the ball disturbance structure 22 helps to precipitate the flue gas in the crude oil. The flue gas is guided to the preheating body through the flue gas circulation structure to heat the preheating body.

[0041] The above structure is disclosed as follows:

[0042] The preheating body includes a preheating furnace and an oil inlet pump and an oil delivery pump connected to the preheating furnace. The preheating furnace introduces crude oil through the provided oil inlet pump. The preheating furnace is connected to the oil pipe 121 through the provided oil delivery pump. The flue gas circulation structure is connected to the preheating furnace. Figure 3 As shown, the flue gas circulation structure includes a circulation pipe 123 arranged on the semi-continuous distillation kettle 12 and connected to the semi-continuous distillation kettle 12. An oil-proof breathable membrane 1231 for preventing crude oil from entering is arranged at the connection point between the circulation pipe 123 and the semi-continuous distillation kettle 12. The circulation pipe 123 is connected to the preheating furnace. The crude oil is pressed into the preheating furnace by the oil feed pump. After being heated to about 250 degrees in the preheating furnace, the crude oil is pumped into the semi-continuous distillation kettle 12 through the oil feed pipe 121 by the oil delivery pump. Fig. 9 As shown by the arrow a in the middle, the flue gas generated when the crude oil is cracked in the semi-continuous distillation kettle 12 is precipitated, and the flue gas is collected by the flue gas circulation structure and guided to the preheating furnace for heating the preheating furnace. Fig. 9 As shown by the middle arrow b, the purpose of this is that the preheating furnace uses hot flue gas to preheat the crude oil, which can not only achieve energy saving effects, but also reduce the reaction time of the device, thereby improving the distillation efficiency.

[0043] After the crude oil enters the semi-continuous distillation kettle 12, under the continuous drive of the oil ball screening structure 21, the ball disturbance structure 22 will drive the energy ball 122 to move so as to achieve uniform heat transfer while avoiding coking. The structure of the ball disturbance structure 22 is disclosed below:

[0044] like Figure 6 , Figure 7 , Figure 8As shown, the ball disturbance structure 22 includes a sleeve 221 that is transmission-connected to the oil ball screening structure 21, an inner wall of the semi-continuous distillation kettle 12 is provided with an inner kettle bracket 124, and a plurality of side brackets 223 are symmetrically provided on both sides of the sleeve 221. The sleeve 221 is horizontally slidably connected to the inner kettle bracket 124 through the side brackets 223, and a sieve plate 224 is provided at the bottom of the side bracket 223. Under the continuous drive of the oil ball screening structure 21, the sleeve 221 drives the side bracket 223 to slide back and forth along the inner kettle bracket 124, thereby making the sieve plate 224 reciprocate in the crude oil and contact with the energy ball 122, and push the energy ball 122 to move horizontally in the crude oil. The moving direction of the sieve plate 224 is as shown in FIG. Fig. 9 As shown by arrow c.

[0045] The ball disturbance structure 22 also includes a bottom plate 222. The inner wall of the semi-continuous distillation kettle 12 is provided with a wall groove 1211. One end of the bottom plate 222 is located in the wall groove 1211 and is slidably connected to the wall groove 1211. A plurality of paddles 225 are equidistantly provided on the bottom plate 222. A top plate 226 is provided on the top of the bottom plate 222. A lifting groove 2261 is provided on the top plate 226. The lifting groove 2261 is a "human" shaped groove. A bottom shaft 2241 is provided at the bottom of the sieve plate 224. The bottom shaft 2241 is located in the lifting groove 2261 and is connected to the lifting groove 2261. 1 sliding connection, the reciprocating movement of the sieve plate 224 drives the bottom plate 222 to move up and down. The specific process is that the sleeve 221 drives the side bracket 223 and then drives the sieve plate 224 to move horizontally along the bracket 124 in the kettle, and the bottom shaft 2241 at the bottom of the sieve plate 224 slides in the lifting groove 2261, so that the bottom plate 222 moves up and down along the wall groove 1211. When the energy ball 122 passes through the paddle 225, it is lifted by the paddle 225 and moves upward. The moving direction of the energy ball 122 is as follows Fig. 9 As shown by the middle arrow d, multiple energy balls 122 can be effectively dispersed, thereby avoiding coking and ensuring uniform heat transfer in the crude oil, and the horizontal reciprocating motion of the sieve plate 224 and the up and down reciprocating motion of the bottom plate 222 can stir the crude oil and accelerate the precipitation of smoke in the crude oil. The distance from the upper dead point to the lower dead point when the bottom plate 222 moves up and down is less than the diameter of the energy ball 122, which prevents some of the energy balls 122 from entering under the bottom plate 222 when the bottom plate 222 moves up and down, causing the bottom plate 222 to be stuck and unable to move down, thereby affecting the movement of the sieve plate 224.

[0046] After the energy ball 122 evenly transfers heat in the crude oil to fully crack the macromolecular substances in the crude oil, the crude oil and oil gas need to be collected and processed separately, such as Figure 5 , Figure 6As shown, the oil ball screening structure 21 includes a three-end pipe and a screen pipe 214. The screen pipe 214 is rotatably connected to one end of the semi-continuous distillation kettle 12 away from the oil pipe 121. The three-end pipe is a pipe with three ports fixedly arranged at one end of the semi-continuous distillation kettle 12 away from the oil pipe 121. The three ports of the pipe are interconnected. One end of the middle of the three-end pipe is located outside the semi-continuous distillation kettle 12 and is connected to the screen pipe 214. One end of the top of the three-end pipe is a first outlet pipe 211, which is an oil and gas outlet connected to the cooler system. One end of the bottom of the three-end pipe is a second outlet pipe 212 for discharging slag. The three-end pipe is fixed with a device for driving the screen pipe. The motor 214 rotates, the screen tube 214 is a hollow tube with a separation net embedded on the surface, the screen tube 214 is coaxially connected with a lead screw 217 at one end away from the motor 213, the lead screw 217 passes through the sleeve 221 and is reciprocatingly threadedly connected with the sleeve 221, the motor 213 is connected to the screen tube 214 through a driving shaft to drive the screen tube 214 to rotate, when the crude oil and oil gas move to the end away from the oil pipe 121 in the semi-continuous distillation kettle 12, the crude oil and oil gas can enter the screen tube 214 through the separation net on the screen tube 214, due to the principle of hot air rising, the oil and gas will enter the cooling system upward through the first outlet pipe 211 after entering the three-end pipe, and the oil and gas will move as shown in the figure. Fig. 9 As shown by the arrow e in the middle, the crude oil will flow downward through the second outlet pipe 212 when it flows to the three-end pipe due to its own weight. Fig. 9 As shown by the middle arrow f, the energy balls 122 in the crude oil are intercepted by the separation net and cannot pass through, and when the screen tube 214 rotates, it drives the sleeve 221 to reciprocate through the coaxially connected lead screw 217.

[0047] Considering that when the crude oil liquid level in the semi-continuous distillation kettle 12 is lower than the height of the sieve tube 214, there is a problem that the crude oil cannot pass through the sieve tube 214. In order to facilitate the separation of the crude oil, Figure 5 , Figure 6 As shown, a hollow disk 215 is provided on the outer wall of the sieve tube 214, and a plurality of disk claws 216 are provided on the side wall of the hollow disk 215. When the sieve tube 214 rotates, the hollow disk 215 is driven to rotate synchronously, so that the disk claws 216 can dig crude oil from a low place, and after lifting the crude oil to a high place, under the action of the crude oil's own weight, the crude oil will flow downward along the surface of the disk claws 216 to the separation net on the sieve tube 214, so that when the crude oil liquid level in the semi-continuous distillation kettle 12 is lower than the height of the sieve tube 214, the crude oil can still be separated by the sieve tube 214, and by setting the angle between the disk claws 216 and the hollow disk 215 to an acute angle, when the disk claws 216 dig the crude oil from a low place and lift the crude oil to a high place, the crude oil can stay in the angle groove formed by the disk claws 216 and the hollow disk 215, thereby avoiding the loss of crude oil during the lifting process, and improving the separation and filtration efficiency of the crude oil.
