Description

TECHNICAL FIELD

[0001] The utility model belongs to waste and old tire cracking technical field especially relates to a novel high temperature oil gas condensing device. BACKGROUND

[0002] Waste and old tire cracking technology is an important process for recycling waste and old tires. Its principle is to heat waste and old tires in an oxygen-free or inert gas environment to decompose them at a certain temperature to produce pyrolysis oil, pyrolysis gas, and carbon black. This technology has the characteristics of green environmental protection and high resource recovery rate, and has been widely used in the field of recycling waste and old tires.

[0003] During the cracking process, the generated high-temperature oil gas needs to be introduced into the condensing device in time for cooling and separation to recover liquid pyrolysis oil and separate out the carbon black dust. In the condensing device, a spiral nozzle is often used to cool and remove dust from the high-temperature oil gas. Specifically, the spiral nozzle sprays the cooling oil into the condensing device in the form of atomized spray. The cooling oil fully contacts the high-temperature oil gas, and through heat exchange, the high-temperature oil gas is condensed into liquid pyrolysis oil, while the carbon black dust is separated and settled.

[0004] However, the spiral nozzle in the existing condensing device has some outstanding problems in actual application. During the condensation process, the high-temperature oil gas generates pyrolysis oil containing carbon black. When this pyrolysis oil combines with carbon black, it forms high-adhesion oil sludge at the nozzle opening of the spiral nozzle. These oil sludges accumulate over time, eventually causing the nozzle channel to narrow or even become blocked. After the spiral nozzle is blocked, the cooling oil cannot be sprayed normally, the cooling and dust removal effect is greatly reduced, and the overall operating efficiency of the condensing device is affected.

[0005] To clean the blocked spiral nozzle, the existing method is usually to stop the machine, disassemble the spiral nozzle, and clean it manually. This process is time-consuming and labor-intensive, and the operation is complex. It requires the cooling system to be completely stopped to complete the cleaning, which seriously affects the running stability and production continuity of the entire device. Frequent shutdown for cleaning also reduces the production capacity of the entire device and affects the production efficiency, especially in large-scale continuous production, the economic loss caused by the shutdown of the entire device is particularly significant.

[0006] To solve the above problems, it is urgent to develop a new type of high-temperature oil gas condensing device, which can clean the spiral nozzle online after it is blocked, avoiding the process of frequent shutdown and manual disassembly and cleaning. The online cleaning of the spiral nozzle can clean the oil sludge and blockage inside the spiral nozzle while the entire device is continuously running, thereby ensuring the cooling and dust removal effect of the condensing device and significantly improving the running stability and production efficiency of the entire device. Therefore, designing a new type of high-temperature oil gas condensing device has become a key technical requirement in the field of waste and old tire cracking technology. Utility model content

[0031] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is described and explained below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application. Based on the embodiments provided by the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] The embodiments of the present application provide a novel high-temperature oil-gas condensing device, which is shown in the figure. Figs. 1-6As shown, the device at least includes a condensing tank 1, an oil injection pipe 3, a sealing connecting pipe 4 and a valve 5. The condensing tank 1 is externally provided with a connecting pipe 2; one end of the oil injection pipe 3 is provided with a spiral spray head 301, and the end of the oil injection pipe 3 provided with the spiral spray head 301 is inserted into the connecting pipe 2 and extends into the condensing tank 1; the sealing connecting pipe 4 is arranged on the outside of the oil injection pipe 3, the inner wall of the sealing connecting pipe 4 and the outer wall of the oil injection pipe 3 form a gap sealing fit, the oil injection pipe 3 is pullably arranged in the sealing connecting pipe 4, and one end of the sealing connecting pipe 4 is detachably connected with the end of the oil injection pipe 3 away from the spiral spray head 301; one end of the valve 5 is connected with the other end of the sealing connecting pipe 4, and the other end is connected with the connecting pipe 2. In actual application, when the spiral spray head 301 needs to be cleaned or maintained, the operator can first realize dynamic sealing through the gap between the outer wall of the oil injection pipe 3 and the inner wall of the sealing connecting pipe 4 when pulling the oil injection pipe 3 outward, and immediately closes the valve 5 after the spiral spray head 301 is pulled out of the valve 5, to prevent the circulation of high-temperature oil gas and ensure the safety of the cleaning operation; after the spiral spray head 301 is completely pulled out, the operator can clean, repair or replace the spiral spray head 301, and after the cleaning is completed, the oil injection pipe 3 is pushed back into the sealing connecting pipe 4 to restore the working position of the spiral spray head 301. The gap sealing fit between the sealing connecting pipe 4 and the outer wall of the oil injection pipe 3 and the double sealing of the valve 5 can effectively prevent the leakage of high-temperature oil gas, ensure the sealing and safety of the system, and realize the online cleaning operation of the blocked spiral spray head 301 under the condition of no shutdown and no temperature reduction, breaking through the limitation that the spiral spray head in the existing condensing device must be shut down and cooled for cleaning.

[0033] In some embodiments, the structure design of the threaded connection between the spiral spray head 301 and the oil injection pipe 3 makes the disassembly and installation of the spiral spray head 301 more convenient; in addition, the threaded connection design can be adapted to different models and specifications of the spiral spray head 301, enhancing the versatility of the device and facilitating the quick replacement of different types of spiral spray heads 301 under different cleaning requirements and working conditions.

[0034] Further, the gap between the inner wall of the sealing connecting pipe 4 and the outer wall of the oil injection pipe 3 is 0.3mm-0.5mm; the design of the gap of 0.3mm-0.5mm ensures the appropriate smoothness of the oil injection pipe 3 during pulling, and at the same time, in the static state, the gap sealing fit can achieve the sealing effect of high-temperature oil gas. The design of the gap ensures the pullability of the oil injection pipe 3 and the sealing performance, avoiding the leakage of oil gas; the range of the gap is verified by experiments, which can achieve the best balance between operation convenience and sealing performance.

[0035] In some embodiments, the gap size can be appropriately adjusted according to the viscosity of the high-temperature oil gas and the working pressure of the system to meet different use environments, and the preferred gap size is 0.5mm.

[0036] Further, the outer wall of the oil injection pipe 3 is provided with a sealing scale groove 302 near one end of the spiral nozzle 301; the sealing scale groove 302 provides a clear visual operation mark for online cleaning operation; when the oil injection pipe 3 is pulled out, the operator can observe the sealing scale groove 302, which indicates that the valve 5 should be closed immediately to form a double seal with the gap, simplifying the operator's work process and judgment basis. Through the visual indication of the sealing scale groove 302, the operator can quickly and accurately judge the pulling depth of the oil injection pipe 3, reducing human operation errors; when the sealing scale groove 302 is exposed, the operator closes the valve 5 in time to form an additional sealing protection to prevent high-temperature oil and gas from leaking.

[0038] Further, the length of the sealing connector 4 is L, the distance from the sealing scale groove 302 to the spiral nozzle 301 is d, and the relationship L>d is satisfied. By controlling the relationship between the length L of the sealing connector 4 and the distance d from the sealing scale groove 302 of the oil injection pipe 3 to the spiral nozzle 301, it is ensured that the oil injection pipe 3 is always in a controlled sealed state during pulling out or inserting. By designing the relationship L>d, it is ensured that the outer wall of the oil injection pipe 3 is always wrapped by the inner wall of the sealing connector 4 during the entire pulling out and inserting process, avoiding the risk of high-temperature oil and gas leakage; whether it is the pulling out operation or the inserting operation of the oil injection pipe 3, the outer wall of the oil injection pipe 3 is always located in the inner cavity of the sealing connector 4, ensuring that the high-temperature oil and gas is always in a sealed environment, eliminating the risk of high-temperature oil and gas leakage, and ensuring the safety and cleanliness of the operating environment; this design is suitable for oil injection pipes 3 of different lengths, and by adjusting the size parameters of L and d, it can be adapted to different use scenarios, enhancing the versatility and flexibility of the cleaning device.

[0039] Further, the sealing connector 4 is provided with a first sealing flange 401 and a second sealing flange 402 at both ends, and the sealing connector 4 is integrally formed with the first sealing flange 401 and the second sealing flange 402. The design of the first sealing flange 401 and the second sealing flange 402 makes the installation and disassembly of the sealing connector 4 more convenient, the flange structure integrally formed reduces the number of parts, enhances the overall rigidity of the device, avoids the risk of loosening that may occur in traditional threaded connections, and improves the sealing performance and durability of the device.

[0040] Further, the oil injection pipe 3 is provided with an oil injection pipe flange 303 at the end away from the spiral spray head 301, and the oil injection pipe flange 303 is connected to the first sealing flange 401 through bolts; by providing the oil injection pipe flange 303 at the end of the oil injection pipe 3 away from the spiral spray head 301 and connecting it to the first sealing flange 401 through bolts, the oil injection pipe 3 can be quickly installed and disassembled. When it is necessary to clean or replace the oil injection pipe 3, only the bolts need to be loosened, and the oil injection pipe 3 can be separated from the sealing connecting pipe 4, realizing efficient device maintenance operation. The bolt connection structure can provide good disassembly convenience under the premise of ensuring sealing performance. By adopting the bolt connection of the oil injection pipe flange 303 and the first sealing flange 401, the disassembly operation of the device is simplified, and the system is convenient for cleaning and maintenance. Compared with the traditional welding connection mode, the bolt connection not only reduces the maintenance cost, but also avoids the influence of high-temperature welding on the performance of the entire device. In addition, the bolt connection has better reusability and can be assembled and disassembled multiple times, prolonging the service life of the device.

[0041] Further, the valve 5 is provided with a first valve flange 501 and a second valve flange 502 at both ends, the valve 5 is integrally formed with the first valve flange 501 and the second valve flange 502, and the first valve flange 501 is connected to the second sealing flange 402 through bolts; the valve 5 is provided with a first valve flange 501 and a second valve flange 502 at both ends, and the valve 5 is integrally formed with the flanges, which makes it have higher reliability in installation and sealing. The first valve flange 501 and the second sealing flange 402 are connected through bolts, which facilitates online disassembly and replacement or maintenance operation of the valve 5; by adopting the integrally formed structure of the flanges, stress concentration and welding defects that may exist in the traditional flange connection are eliminated, and the strength and reliability of the connection part are improved. In addition, the bolt connection of the first valve flange 501 and the second sealing flange 402 facilitates online replacement of the valve 5, reduces maintenance time, and improves the operation efficiency of the device.

[0042] Further, the connecting pipe 2 is provided with a connecting pipe flange 201, and the connecting pipe flange 201 is connected to the second valve flange 502 through bolts; the connecting pipe 2 is connected to the second valve flange 502 through flanges. This design makes the assembly and disassembly of the entire device more convenient, facilitating on-site maintenance and replacement of the connecting pipe 2; through the bolt connection, the connection part of the connecting pipe 2 and the valve 5 has high sealing performance and operability, and the operator can quickly disassemble and assemble the connecting pipe 2, facilitating cleaning and maintenance of the spiral spray head 301; the bolt connection of the connecting pipe flange 201 and the second valve flange 502 makes the assembly flexibility of the device higher, reducing the disassembly and maintenance time; in addition, the bolt connection has high reusability, improving the maintainability of the device; compared with the welding connection mode, the flange connection can avoid the damage to the material performance caused by high-temperature welding, prolonging the service life of the device.

[0043] Further, sealing washers are arranged between the oil injection pipe flange 303 and the first sealing flange 401, between the first valve flange 501 and the second sealing flange 402, and between the connecting pipe flange 201 and the second valve flange 502. The sealing washers are compressed when the bolts are tightened, filling the uneven areas of the flange surfaces and further improving the sealing effect of the high-temperature oil and gas. By adding sealing washers at the connection points of the oil injection pipe flange 303 and the first sealing flange 401, the first valve flange 501 and the second sealing flange 402, and the connecting pipe flange 201 and the second valve flange 502, the sealing performance of the system is significantly improved, preventing high-temperature oil and gas leakage and ensuring the safety of the system. In addition, the sealing washers are made of various materials, such as high-temperature and corrosion-resistant materials, to meet different working environment requirements.

[0044] In some embodiments, the material of the sealing washer can be graphite gasket, metal gasket, or rubber washer to adapt to different temperature and pressure working environments; the shape of the sealing washer can be designed as a flat washer, a corrugated washer, or a ring washer according to the surface characteristics of the flange.

[0045] Further, the valve 5 is a stainless steel ball valve, and a rotating handle 503 is arranged on the stainless steel ball valve. The stainless steel material enables the valve 5 to work normally in a high-temperature and high-corrosion environment. The valve 5 adopts a stainless steel ball valve structure. The rotation angle of the ball is controlled by the rotating handle 503, thereby realizing the opening and closing operation of the valve 5. The stainless steel material enables the valve 5 to work normally in a high-temperature and high-corrosion environment. The stainless steel ball valve is resistant to high temperature and corrosion, and is easy to operate and flexible in switching, in combination with the design of the rotating handle 503.

[0046] In some embodiments, the valve 5 can be a pneumatic control valve or an electric control valve to meet the demand for automatic control.

[0047] The working process of the above-mentioned new high-temperature oil and gas condensing device is as follows:

[0048] When the spiral nozzle 301 is blocked, the operator first removes the bolts between the oil injection pipe flange 303 and the first sealing flange 401, so that the oil injection pipe 3 is in a free state that can be pulled out. Then, the oil injection pipe 3 is pulled out along the axial direction, and in the process of pulling out, the inner wall of the sealing connecting pipe 4 and the outer wall of the oil injection pipe 3 are in clearance fit, so that the oil injection pipe 3 is always in a dynamic sealing state during the pulling-out process, preventing high-temperature oil and gas from leaking out. Continue to pull out the oil injection pipe 3 until the sealing scale groove 302 on the oil injection pipe 3 is exposed, and the operator immediately closes the valve 5 to form a double sealing barrier of dynamic sealing and valve sealing, ensuring that the high-temperature oil and gas in the system is completely isolated; at this time, the oil injection pipe 3 is completely pulled out for cleaning the spiral nozzle 301; after the spiral nozzle 301 is cleaned, the operator reinserts the oil injection pipe 3 into the sealing connecting pipe 4, and in the process of insertion, the gap seal between the outer wall of the oil injection pipe 3 and the inner wall of the sealing connecting pipe 4 continues to play a role, ensuring that the high-temperature oil and gas will not leak out. When the sealing scale groove 302 of the oil injection pipe 3 is completely inserted into the sealing connecting pipe 4, the operator opens the valve 5 to restore the flow of high-temperature oil and gas in the system, and then continues to insert the oil injection pipe 3 until the oil injection pipe flange 303 is in butt joint with the first sealing flange 401, and the two are fastened and connected together through bolts, ensuring the axial fixation of the oil injection pipe 3, avoiding loosening or falling off during the operation of the equipment. Thus, the online cleaning work of the spiral nozzle in the condensing device is completed.
