Description

Technical Field

[0001] The present invention relates to the technical field of waste heat recovery of industrial furnaces, and specifically to an energy-saving and emission-reducing industrial furnace tube pipeline waste heat utilization system. Background Art

[0002] An industrial furnace refers to a device or apparatus used for high-temperature heating, sintering, melting, drying, calcining and other industrial processes. They are usually used in various manufacturing, processing and treatment processes, including metal processing, ceramic production, glass manufacturing, chemical reactions, heat treatment, roasting, distillation, drying, baking, etc. The main function of an industrial furnace is to provide a high-temperature environment to achieve specific material transformation, treatment or processing requirements. They are usually made of high-temperature resistant materials with good heat conduction and heat insulation properties to ensure the stability and safety of the high-temperature internal environment. According to different application and process requirements, industrial furnaces can adopt different heating methods, including electric heating, gas heating, oil heating, coal heating, etc. The furnace is usually equipped with a temperature control system, a ventilation system, an emission treatment system, etc. to ensure the control of operation and the safety of the environment. There are various types and forms of industrial furnaces, including tunnel furnaces, rotary furnaces, box furnaces, tube furnaces, horizontal furnaces, vertical furnaces, etc. Their design and scale can be customized according to specific applications and production requirements. Industrial furnace waste heat recovery refers to the process of effectively collecting and utilizing the waste heat generated during the operation of an industrial furnace. When an industrial furnace conducts high-temperature heating or other heat treatment processes, a large amount of heat energy is usually dissipated into the environment in the form of waste heat. Through a waste heat recovery system, this waste heat can be captured and utilized for other purposes, thereby improving energy utilization efficiency and saving energy consumption. During the process of discharging exhaust gas through pipelines in an industrial furnace, the exhaust gas often contains a large amount of heat, and this part of the heat needs to be recovered and processed through a dedicated recovery system.

[0003] However, the existing methods for waste heat recovery of industrial furnace pipelines have the following problems: The traditional method is to add a jacket outside the pipeline and use a pump for circulating heat exchange to achieve waste heat recovery and utilization. However, for the transformation of an already built conveying pipeline, the construction difficulty is large and the operation cycle is long; secondly, when using jacket heat exchange, the heat exchange rate is not easy to control, which is prone to forming dead zones, resulting in caking inside the solid-phase conveying pipeline and affecting the normal operation of the solid-phase external conveying equipment. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , the present invention provides a technical solution: an energy-saving and emission-reduction type industrial furnace tube pipeline waste heat utilization system, which includes an industrial furnace pipeline 1 and an industrial furnace pipeline waste heat recovery system installed on the industrial furnace pipeline 1. The industrial furnace pipeline waste heat recovery system includes a telescopic heat-insulating outer tube, a moving component, a passive waste heat absorption tube, and a water guiding component. The telescopic heat-insulating outer tube includes a locking collar 2, a mounting ring 3, a telescopic heat-insulating outer sleeve 4, and a clamping plate 5. The locking collar 2 and the mounting ring 3 are symmetrically fixed on the telescopic heat-insulating outer sleeve 4 left and right. The locking collar 2 is fixed on the flange of the industrial furnace pipeline 1. The telescopic heat-insulating outer sleeve 4 is installed on the industrial furnace pipeline. The clamping plate 5 is provided with several groups and evenly installed on the telescopic heat-insulating outer sleeve 4. The moving component is installed at the right end of the mounting ring 3. The passive waste heat absorption tube is placed inside the telescopic heat-insulating outer sleeve 4. The water guiding component includes a pump 6, a water inlet pipe 7, a drain pipe 8, and a pump 9. The pump 6 is connected to the left end of the passive waste heat absorption tube through the water inlet pipe 7. The drain pipe 8 is installed at the right end of the passive waste heat absorption tube and is connected to the pump 9 at the lower end. In addition, the locking collar 2, the mounting ring 3, and the telescopic heat-insulating outer sleeve 4 are all of a split structure;

[0028] The locking outer ring 33 includes a half ring 10, a half ring 11, a side plate 12, and a limiting plate 13. One end of the half ring 10 and the half ring 11 is rotatably connected and the other end is fixed by bolts. The side plates 12 are provided with two groups and are respectively installed on the half ring 10 and the half ring 11. The limiting plates 13 are provided with two groups and are respectively inserted through the two groups of side plates 12. The limiting plate 13 is in contact with the flange of the industrial furnace pipeline 1;

[0029] The telescopic heat-insulating outer sleeve 4 includes two groups of arc-shaped outer sleeves 14 arranged symmetrically and ridges 15 respectively fixed on the tops of the two groups of arc-shaped outer sleeves 14. The arc-shaped outer sleeve 14 is made of polyethylene material and the surface is processed into a laminated structure. The ridge 15 is also designed as a laminated structure. The clamping plate 5 is provided with several groups and evenly arranged between the two groups of ridges 15. Such a design method is convenient for fully wrapping the telescopic heat-insulating outer sleeve 4 around the industrial furnace pipeline 1 for heat treatment;

[0030] The moving assembly includes an inner ring 16, a driver 17, a driven ring 18, and an adjustable driving mechanism 19. The inner ring 16, the driven ring 18, and the adjustable driving mechanism 19 are all split structures. The inner ring 16 is embedded in the right side of the mounting ring 3. The driver 17 is installed on the inner ring 16. The driven ring 18 is rotatably arranged on the inner ring 16 and used in cooperation with the driver 17. The adjustable driving mechanism 19 is located inside the driven ring 18 and is built into the inner ring 16. When it is necessary to traction and stretch the telescopic heat-insulating jacket 4 and the driven waste heat absorption pipe, the driving motor 22 drives the driving gear 23 to rotate. During the rotation of the driving gear 23, it acts on the driven ring 18, so that the pushing block 26 on the inner side of the driven ring 18 acts on the bearing plate 28 of the elastic ring 27. The elastic ring 27 deforms, causing the bearing plate 28 to move inward, and finally making the wheel body 31 contact the surface of the industrial furnace pipe 1. Through the drive of the wheel body 31 by the motor 30, the moving assembly traction telescopic heat-insulating jacket 4 and the driven waste heat absorption pipe are synchronously extended and adjusted;

[0031] The driven waste heat absorption pipe is composed of a metal water guide pipe 20. The metal water guide pipe 20 is in a spiral structure and is formed with a number of drainage rings 21. Two openings are formed at the upper end of the drainage ring 21, and the two openings are respectively fixed on the inner walls of the two arc-shaped jackets 14. The water is spirally guided by the driven waste heat absorption pipe, and the heat on the outer wall of the industrial furnace pipe 1 is absorbed and processed in all directions during the guiding process.

[0032] Further improved, as Figure 1 shown: The clamping plate 5 is in an inverted U-shaped structure and is made of elastic metal material. The clamping plate 5 is buckled on the two convex strips 15, and the convex strips 15 are clamped by the clamping plate 5 to achieve the purpose of closing the upper end of the telescopic heat-insulating jacket 4.

[0033] Further improved, as Figure 2 shown: The driver 17 includes a driving motor 22 and a driving gear 23 installed at the power output end of the driving motor 22.

[0034] Further improved, as Figure 2 shown: The driven ring 18 includes a ring body 24 and a number of sets of teeth 25 formed on the periphery of the ring body 24. The teeth 25 are engaged with the driving gear 23. A number of sets of pushing blocks 26 are formed inside the ring body 24. The pushing blocks 26 are in a fan-shaped structure and the thickness of one end is greater than that of the other end.

[0035] Further improved, as Figure 3As shown in the figure: The adjustable drive mechanism 19 includes an elastic ring 27, a bearing plate 28, a mounting bracket 29, a motor 30, and a wheel body 31. The elastic ring 27 is in a ring structure. The bearing plates 28 are divided into several groups and are distributed in one-to-one correspondence with the push blocks 26. The mounting bracket 29 is installed inside the bearing plate 28. The motor 30 is installed on the mounting bracket 29 and its power output end is connected to the wheel body 31. By driving the drive gear 23 to rotate through the drive motor 22, the drive gear 23 acts on the driven ring 18 during rotation, so that the push block 26 inside the driven ring 18 acts on the bearing plate 28 of the elastic ring 27. The elastic ring 27 deforms, causing the bearing plate 28 to move inward, and finally making the wheel body 31 contact the surface of the industrial furnace pipeline 1. Through the drive of the motor 30 on the wheel body 31, the moving assembly traction telescopic heat insulation jacket 4 and the driven waste heat absorption pipe are stretched and adjusted synchronously.

[0036] Further improved, as Figure 3 shown in the figure: Several groups of elastic pieces 32 are formed on the surface of the elastic ring 27. Adjacent two groups of elastic pieces 32 are respectively located on both sides of the bearing plate 28. The elastic pieces 32 are made of elastic metal material and are in a laminated structure. Such a design method is convenient for deforming and adjusting the elastic ring 27 as needed, so that the wheel body 31 can better contact the industrial furnace pipeline 1.

[0037] Further improved, as Figure 3 shown in the figure: The wheel body 31 is installed on the mounting bracket 29 and its surface is in a corrugated structure. The wheel body 31 contacts the surface of the industrial furnace pipeline 1, which can achieve the purpose of anti-slip and is convenient for better traction and stretching of the telescopic heat insulation outer pipe and the driven waste heat absorption pipe.

[0038] Specifically, the drainage ring 21 includes an outer ring 33 and several groups of inner rings 34 placed inside the outer ring 33. Adjacent two groups of inner rings 34 are connected end to end. The inner rings 34 are made of elastic metal material and contact the outer wall of the industrial furnace pipeline 1. By arranging several groups of inner rings 34 inside the outer ring 33, the heat-conducting water can be introduced into the inner rings 34, and better heat absorption can be achieved through the contact between the inner rings 34 and the outer wall of the industrial furnace pipeline 1.

[0039] During use: When the industrial furnace pipeline waste heat recovery system of the present invention needs to be installed, the staff can place the locking outer ring 33 on one side of the flange of the industrial furnace pipeline 1, and then rotate the telescopic heat-insulating outer pipe, the moving assembly, and the driven waste heat absorption pipe so that the three are closed and fixed. By moving the limit plate 13, the limit plate 13 is placed on one side of the flange and positioned to achieve the purpose of locking the locking outer ring 33. Then, the convex strip 15 is fixed and sealed by the clamping plate 5. At this time, the upper two openings of the drainage ring 21 are also in a closed state. When the telescopic heat-insulating outer sleeve 4 and the driven waste heat absorption pipe need to be tractionally stretched, the driving motor 22 drives the driving gear 23 to rotate. During the rotation of the driving gear 23, it acts on the driven ring 18, so that the pushing block 26 inside the driven ring 18 acts on the bearing plate 28 of the elastic ring 27. The deformation of the elastic ring 27 causes the bearing plate 28 to move inward, and finally the wheel body 31 contacts the surface of the industrial furnace pipeline 1. Through the drive of the motor 30 on the wheel body 31, the moving assembly tractionally stretches the telescopic heat-insulating outer sleeve 4 and the driven waste heat absorption pipe synchronously for adjustment. When the telescopic heat-insulating outer sleeve 4 and the driven waste heat absorption pipe are fully stretched, the water pump 6 is used to introduce water into the water inlet pipe 7 and introduce it into the driven waste heat absorption pipe. By arranging a number of inner rings 34 inside the outer ring 33, the heat-conducting water can be introduced into the inner rings 34, and better heat absorption can be achieved through the contact between the inner rings 34 and the outer wall of the industrial furnace pipeline 1. After heat absorption, external pumping treatment is carried out through the water pump 9, so as to achieve the purpose of efficient recovery of the waste heat of the industrial furnace pipeline 1.
