Description

Technical Field

[0001] The invention belongs to the technical field of solid waste recycling systems, and in particular relates to a fully continuous waste tire oil refining, cooling and purification system and method. Background Art

[0002] Waste tire oil refining is an effective waste treatment method that can convert discarded tires into useful energy and materials; waste tires need to be pre-processed. Usually, a crusher is used to cut the tires into small pieces, and then a magnetic separator is used to remove metal impurities. In addition, the tire fragments need to be screened to remove larger impurities, and the pre-treated waste tire fragments need to be pyrolyzed. During the pyrolysis process, the organic matter in the tire fragments is converted into oil, gas and solid residue. These oils and gases can be further refined into fuel oil or other useful chemicals.

[0003] At present, in the process of refining waste tires, intermittent refining is generally adopted. Due to the imperfect sealing of the current refining system and poor sealing, excessive air will enter the cracking furnace under the micro-negative pressure environment of the cracking furnace. The air and the cracked oil and gas will undergo oxidation reaction under high temperature, which not only affects the oil yield, but also produces excessive carbon black due to the oxidation of oil and gas. The carbon black will be transported downward with the oil and gas and adsorbed on the inner wall of the pipeline, which will cause blockage to the downstream transportation pipeline. Therefore, the general refining system needs to be shut down after working for 12-24 hours, and the pipelines that are easy to be blocked are cleaned manually to clean the carbon black on the inner wall of the pipeline. In this way, not only time and energy are spent on cleaning the carbon black, but also the normal production efficiency of the whole set of equipment is affected. Due to the suspension and restart of the system, the suspension of the cracking furnace will cause a lot of waste heat waste, and it takes a long time to restart the cracking furnace to reach the working temperature, which will also cause a lot of heat energy waste, thus affecting the economic benefits of the whole system. A continuous purification system is needed to reduce the number of shutdowns, prolong the continuous working time, and improve the economic benefits. Summary of the invention

[0043] The hot water outlet end of the heat exchanger 10 is connected to a cooler 11 , and a water pool 12 is provided below the cooler 11 . The water cooled by the cooler 11 is put into the cooling pool, and the water inlet end of the heat exchanger 10 draws the cold water in the water pool 12 .

[0044] The driving mechanism arranged on the outer wall of the sealing cover 102 and the sealing cover 203 is a hydraulic cylinder 106, which drives the sealing cover 102 and the sealing cover 203 to move relative to each other. A plurality of screws 105 are arranged at one end of the sealing cover 102 close to the sealing cover 203, and the sealing cover 102 and the sealing cover 203 are connected by the screws 105; a first baffle ring 201 is arranged on the inner wall of the sealing cover 2, and the first baffle ring 201 is arranged close to the end of the discharge port 101, and a second baffle ring 104 is arranged on the side of the sealing cover 203 close to the discharge port 101, and the first baffle ring 201 and the second baffle ring 104 are both arranged close to the outer wall of the discharge port 101, and the sealing body 102 adopts graphite packing, which is annular in structure and is arranged around the discharge port 101, and the graphite packing is arranged between the first baffle ring and the second baffle ring along the axial direction of the discharge port 101; a plurality of hydraulic cylinders 106 are evenly arranged on the sealing cover 102 and the sealing cover 203 along the circumferential direction.

[0045] A driving motor 107 is provided on the base below the cracking furnace, and the driving motor 107 is connected to a reducer 108. The reducer 108 is drivingly connected to a small gear 109, and the small gear 109 is meshingly connected to a large gear 110. The large gear 110 is fixed to the outer wall of the cracking furnace, and a roller 111 is connected to the side of the small gear 109 away from the reducer 108.

On the basis of the graphite packing being able to form a rotation, the sealing cover 102 and the sealing cover 203 are tightened by the screw 105. The graphite packing is subjected to the clamping force of the first baffle ring 201 and the second baffle ring 104, and is better sealed with the discharge port 101 through the pressure, thereby achieving a good sealing basis; however, due to the friction of the graphite packing, High temperature is generated. The high temperature environment will aggravate the wear and consumption of the graphite packing. When the graphite packing is worn to a certain extent, it will affect the sealing effect. Due to the slightly negative pressure environment in the cracking furnace 1, the outside air will enter the cracking furnace 1, thereby causing the oil and gas to be oxidized at high temperature and reducing the oil yield. When the graphite packing is worn to a certain extent, a gap will be formed between the discharge port 101 and the sealing cover 1 2 and the sealing cover 2 103. The existence of the gap will cause the cracking furnace 1 to sag during the rotation process, causing the discharge ports 101 at both ends of the cracking furnace 1 to be not located on the same center of a circle, causing the cracking furnace 1 to be rotated. Polarization occurs in the furnace, thereby causing deflection and instability of the furnace body, affecting the normal use of the cracking furnace 1; in the present technical solution, a plurality of hydraulic cylinders 106 are arranged on the outer peripheral side of the sealing cover 102 and the sealing cover 203. When the graphite packing is worn and a gap is generated between the sealing cover 102 and the sealing cover 203, the hydraulic cylinder 106 can be driven to drive the sealing cover 102 and the sealing cover 203 to move closer to each other, and the graphite packing is squeezed by the first baffle ring 201 and the second baffle ring 104, so that the graphite packing is pressed against the sealing cover 102, the sealing cover 203 and the sealing cover 203. The gap between the discharge ports 101 is filled to re-form the seal. Compared with the existing connection method through the screw 105, good sealing can be achieved without stopping the machine, and the operability is strong and the sealing is better. The hydraulic cylinder 106 can provide continuous and effective pulling force to the sealing cover 2 and the sealing cover 103, which can effectively prevent the unstable operation of the cracking furnace 1 caused by the gap. It should be understood that the hydraulic cylinder 106 is arranged on the peripheral side of the sealing cover 2, and the number of hydraulic cylinders 106 can be set according to the diameter of the discharge port 101, and the specific number is not limited.

[0046] refer to Figure 6-8On the basis of the first embodiment, specifically, the outer wall of the sealing cover 2 is further provided with a reminder unit 202, and the reminder unit 202 includes a box body 2021, and a heat conductor is provided inside the box body 2021. The heat conductor transfers the heat of the friction of the graphite packing to the heat expansion ball 20213. The heat expansion ball 20213 expands due to the heat and drives the color ball 20217 in the channel 20211 of the ball shell 2028. By observing the distance that the color ball 20217 extends in the channel 20211, the friction contact between the graphite packing and the sealing cover 2 can be judged, and then the wear of the graphite packing can be judged; the sealing cover 1 and the sealing cover 2 can be provided with 4, 6, or 8 hydraulic cylinders on the sides, which are selected according to the diameter of the discharge port, and the discharge port diameter is greater than 50 cm and less than 80cm, use 4 hydraulic cylinders; if the diameter of the discharge port is greater than 80cm and less than 120cm, use 6 hydraulic cylinders; if the diameter of the discharge port is greater than 120cm and less than 160cm, use 8 hydraulic cylinders; the discharge port with a larger diameter is selected according to the actual situation; a reminder unit is provided near each hydraulic cylinder, and the wear of the local graphite packing can be judged by the set reminder unit. When the local graphite packing is severely worn, the hydraulic cylinder at the nearby position is started to drive the sealing cover 1 to move and press the graphite packing laterally. The graphite packing is compressed and re-approaches the sealing cover 1 and the discharge port wall, so that the graphite packing is tightly connected with the sealing cover 1 and the discharge port again, and the seal is re-formed to avoid oil and gas leakage.

[0047] By setting the reminder unit 202, observing the distance that the color ball 20217 extends out of the channel 20211 of the ball shell 2028, the wear condition of the graphite packing can be judged. By visually observing the wear condition of the graphite packing, the distance between the sealing cover 1 2 and the sealing cover 2 103 is adjusted in time by the hydraulic cylinder 106 to compress the graphite packing, which can timely prevent the gap caused by excessive wear of the graphite packing, resulting in poor sealing and air intake problems; specifically, a heat absorbing block 20 is provided at one end of the box body 2021 of the reminder unit 202 near the graphite packing 22, the heat absorbing block 2022 is connected to a heat conducting rod 2023, the other end of the heat conducting rod 2023 is connected to a temperature memory spring 2024, the temperature memory spring 2024 is made of nickel-titanium memory alloy, and the phase change temperature is above 400°C, the other end of the temperature memory spring 2024 is spaced apart with a heat transfer block 2025, the other side of the heat transfer block 2025 is connected to a heat transfer rod 2026, the heat transfer block 2025 and the heat transfer rod 2026 are both made of metal, the side of the box body 2021 away from the sealing cover 2 is connected to a transparent cover 2027, and the transparent cover 2027 is made of durable High temperature glass, a spherical shell 2028 is arranged in a transparent cover 2027, the spherical shell 2028 is connected with a support rod 2029, and is connected to the inside of the transparent cover 2027 through the support rod 2029, a heat expansion ball 20213 is arranged in the spherical shell 2028, and the heat expansion ball 20213 is made of thermoplastic polytetrafluoroethylene, which has good thermal expansion; the inner wall of the spherical shell 2028 is provided with a heat insulation layer 20210, and the heat insulation layer 20210 is made of one or more of glass fiber, asbestos, rock wool, and silicate, and a gap is formed between the heat insulation layer 20210 and the heat expansion ball 20213, and the insulation The thermal layer 20210 is provided with at least one channel 20211, and a movable color ball 20217 is provided inside the channel 20211.

The color ball 20217 is connected to a guide rod 20216, and the other end of the guide rod 20216 is connected to an arc block 20214, and the arc block 20214 abuts against the heat expansion ball 20213. The guide rod 20216 is provided with a first spring 20215, and one end of the first spring 20215 is connected to the arc block 20214, and the other end is connected to the thermal insulation layer 20210.

[0048] Specifically, the working process of the reminder unit 202 is as follows: the heat absorbing block 2022 is arranged close to the graphite packing, and the friction heat between the graphite packing and the sealing cover 2 is transferred to the heat conducting rod 2023 and the temperature memory spring 2024 through the heat absorbing block 2022. The temperature memory spring 2024 is elongated and deformed at a specific temperature. The other end of the temperature memory spring 2024 is connected to the heat transfer block 2025 for heat transfer, and the heat is transferred to the heat transfer rod 2026. The heat transfer rod 2026 transfers the heat to the heat expansion ball 20213 through the metal heat conductive sheet 20212, and the metal heat conductive sheet 20212 is an elastic metal. It should be understood that the temperature memory spring 2024 is made of nickel-titanium metal. The nickel-titanium metal memory spring 2024 is made of nickel-titanium metal. The memory alloy can be deformed above 400 degrees Celsius. Since the cracking temperature of the cracking furnace 1 is between 400 and 450 degrees Celsius, the nickel-titanium temperature memory spring 2024 is set to deform and conduct heat when the temperature reaches the set deformation condition; the graphite packing works in the high temperature environment of the cracking furnace 1. Under normal circumstances, the temperature of the graphite packing is lower than the temperature of the cracking furnace 1. When the graphite packing does not rotate, the temperature of the graphite packing will rise due to friction when it rotates. Therefore, the excess heat is transferred to the temperature memory spring 2024, which will cause deformation; the heat expansion ball 20213 absorbs heat and expands, and then pushes the arc block 20214 to move, and the arc block 20214 pushes the guide rod 20216 and the color ball 202 17 moves, changes the extension length of the color ball 20217 in the channel 20211, and observes the extension length of the color ball 20217 through the transparent cover 2027 to determine the contact between the graphite packing and the sealing cover 2; when the graphite packing is in good contact with the sealing cover 2 and the discharge port 101 and there is no gap, the graphite packing generates more heat due to friction, and more heat is transferred to the heat expansion ball 20213. The heat expansion ball 20213 has a large expansion volume, which pushes the guide rod 20216 and the color ball 20217 to extend a long distance in the channel 20211; when the graphite packing is not in good contact with the sealing cover 2 and the discharge port 101 and there is a gap, the graphite packing friction The force is reduced, the heat generated by the friction force is reduced, and less heat is transferred to the heat expansion ball 20213. The expansion volume of the heat expansion ball 20213 is small, and the distance that the guide rod 20216 and the color ball 20217 are pushed out in the channel 20211 is short; and through the first spring 20215, through the rebound force, when the heat expansion ball 20213 absorbs less heat, the guide rod 20216 and the color ball 20217 are driven to reset in the channel 20211; and by setting a heat insulation layer 20210 on the outside of the heat expansion ball 20213, the error of the expansion of the heat expansion ball 20213 caused by external heat is prevented, and the accuracy of the display of the color ball 20217 is further increased. Therefore, the wear of the graphite packing can be judged by the reminder unit 202, so as to timely control the hydraulic cylinder 106 to seal, form a good seal, and prevent the outside air from entering. Example

[0049] On the basis of Example 1, the purification method using the fully continuous waste tire oil refining cooling and purification system includes:

[0050] S1, waste tire particles are cracked into hydrocarbon-rich oil and gas under high temperature in the cracking furnace 1, and the oil and gas enter the spray tank 3 through the sealing cover 2, and are sprayed by the spray head arranged in the spray tank 3 to preliminarily cool the high-temperature oil and gas. The spray tank 3 sends the cooled oil and gas into the capture bin 4 through the horizontal material pipe 37 at the top, and the oil and gas are sprayed again in the capture bin 4. The temperature of the spray liquid in the capture bin 4 is lower than the temperature in the spray tank 3. The oil and gas are condensed and liquefied in the capture bin 4 and enter the oil storage tank 6 through the oil discharge port;

[0051] S2, the remaining oil and gas in the capture bin 4 enters the condenser through the air pipe for re-cooling, and the cooled gas passes through the oil storage tank 6, the outlet pipe of the oil storage tank 6 is connected to the air pump, and the air pump draws the gas in the oil storage tank 6 into the gas storage tank 8, and the gas storage tank 8 supplies gas to the cracking furnace 1 through the air pipe, and the excess gas is stored;

[0052] S3, in the above process, the water in the hydration capture chamber 4 in the spray tank 3 is pumped to the filter tank 9 by a water pump, and the filter arranged in the filter tank 9 filters the carbon black. The filter adopts an ultrafiltration membrane, and the minimum filtration diameter of the ultrafiltration membrane is 1 μm, which can completely filter the carbon black. The filtered water is sent to the heat exchanger 10, and the hot water in the heat exchanger 10 is sent to the cooler 11 for cooling. After cooling, it is sent back to the spray tank 3 and the capture chamber 4 for spraying, and is sent to the condensation tank 7 at the same time. No new cooling water needs to be added in the whole process, and the system is self-sufficient.

[0053] During the whole process, when the mixed oil and gas enters the spray tank 3 through the discharge port 101 and the feed pipe 33, the rotating blades 34 are driven by the servo motor 31 to rotate forward or reversely, and the carbon black accumulated on the inner wall of the feed pipe 33 is scraped and sent to the spray tank 3 or the cracking furnace 1 to prevent the carbon black from adhering to and depositing on the inner wall of the feed pipe 33, thereby avoiding the need to shut down the entire system for manual cleaning, thereby extending the operation time of the entire system; the oil and gas continue to enter the horizontal pipe 37 from the vertical pipe 35 at the top of the spray tank 3, and then enter the capture bin 4. In order to prevent carbon black from adhering and depositing on the inner wall of the vertical material pipe 35 or the horizontal material pipe 37, a first telescopic cylinder 36 and a second telescopic cylinder 38 are respectively arranged at the other end of the vertical material pipe 35 and the free end of the horizontal material pipe 37. The first telescopic cylinder 36 and the second telescopic cylinder 38 move to drive the scraper plate 310 to scrape the inner wall of the horizontal material pipe 37 and the vertical material pipe 35, thereby cleaning the carbon black adhering to the inner wall to prevent the horizontal material pipe 37 and the vertical material pipe 35 from being blocked. This also effectively extends the operation time of the entire system, so that the continuous operation time of the entire system can reach 7 days, improve the oil yield, and improve the economic benefits. A "U"-shaped pipe is arranged between the oil outlet of the capture bin 4 and the oil storage tank 6, which can prevent the oil and gas in the capture bin 4 from directly entering the oil storage tank 6, which not only affects the air pressure balance of the entire system, but also reduces the oil yield when the oil and gas directly enter the oil storage tank 6. The entire system adopts a water circulation system and does not require external water supply. The hot water after spraying in the spray tank 3 and the capture bin 4 is cooled by the heat exchanger 10 and the cooler 11. After cooling, it is sent back to the spray tank 3 and the capture bin 4 for spraying. The outer tube of the carbon black discharge mechanism 13 is a double-layer structure, and the outer tube of the carbon black discharge mechanism 13 is cooled by water.
