Description

Technical Field

[0001] This utility model relates to the field of boiler technology, and more specifically, to a gasification furnace organic heat carrier boiler structure. Background Technology

[0002] In the field of boiler technology, organic heat carrier boilers, as an important heat energy conversion device, are widely used in various stages of industrial production. However, traditional organic heat carrier boilers have certain limitations in structural design and performance. For example, the "Organic Heat Carrier Furnace with Biomass Pellet Reciprocating Grate" (Chinese Patent Publication No. CN201921442192) is ineffective in waste heat recovery, with the exhaust gas still containing a large amount of unused waste heat, resulting in low resource utilization. Furthermore, in some organic heat carrier boilers paired with traditional gasifiers, the heat exchange efficiency is low, leading to significant energy waste and failing to meet the current industrial demand for efficient and energy-saving equipment. In addition, some existing boilers have complex structures, high maintenance costs, and require improvement in safety and stability. Against this backdrop, developing a new type of organic heat carrier boiler structure for gasifiers is of significant practical importance, effectively addressing the shortcomings of existing technologies and improving the energy efficiency and economic benefits of industrial production. Utility Model Content

[0003] The purpose of this utility model is to provide a gasifier organic heat carrier boiler structure to solve the problems mentioned in the background art, such as the low heat exchange efficiency and serious energy waste in some traditional gasifier-matched organic heat carrier boilers, which make it difficult to meet the current industrial production demand for high-efficiency and energy-saving equipment.

[0004] To achieve the above objectives, this utility model provides a gasifier organic heat carrier boiler structure, including a shell, with a radiation group and a convection group arranged inside the shell. One end of the radiation group is connected to the convection group, and the other end of the radiation group is provided with a flue gas inlet. The end of the convection group away from the radiation group is provided with a flue gas outlet. The radiation group includes radiant heat exchange tubes distributed in a ring on the inner wall of the shell, and the convection group includes convection heat exchange tubes arranged in a serpentine pattern inside the shell.

[0005] This system incorporates radiant and convection heat exchange tubes within the casing. One end of the radiant tubes connects to the flue gas inlet, and the other end connects to the convection tubes. The end of the convection tubes furthest from the radiant tubes is the flue gas outlet. The radiant heat exchange tubes of the radiant tubes are arranged in a ring around the inner wall of the casing, absorbing heat through radiant heat transfer from the high-temperature flue gas. The convection heat exchange tubes of the convection tubes are arranged in a serpentine pattern within the casing, transferring heat to the convection tubes through forced convection between the hot flue gas and the tubes. The hot flue gas enters the radiant tubes from the flue gas inlet, undergoes radiant heat exchange, then enters the convection tubes, and finally exits from the flue gas outlet, continuously transferring heat to the heat transfer oil throughout the process.

[0006] Preferably, the bottoms of the radiation group and the convection group are supported by a foundation.

[0007] This foundation provides stable support for the radiant and convection boiler units, ensuring the entire boiler structure remains stable on the ground. The foundation can withstand the weight of the radiant and convection boiler units and the internal medium, distributing gravity evenly across the ground and preventing the equipment from sinking or tilting due to excessive localized stress.

[0008] Preferably, the convection group includes upper and lower groups, with the bottom of the upper convection group connected to an upper heat transfer oil inlet pipe and the bottom of the lower convection group connected to a lower heat transfer oil inlet pipe.

[0009] This configuration divides the convection group into upper and lower sections, connected to the upper and lower heat transfer oil inlet pipes respectively. Heat transfer oil enters the convection group through both inlet pipes. This design allows the heat transfer oil to exchange heat in both the upper and lower convection groups, forming different circulation paths. In actual operation, the flow rate of heat transfer oil entering the upper and lower convection groups can be flexibly adjusted according to different operating conditions, achieving precise control of the heat exchange process.

[0010] Preferably, valves are installed at the ends of the upper and lower heat transfer oil inlet pipes.

[0011] This valve is installed at the ends of both the upper and lower heat transfer oil inlets. By controlling the valve opening, the flow rate of the heat transfer oil can be adjusted. When the valve is fully open, the heat transfer oil flow rate is at its maximum; as the valve is gradually closed, the flow rate gradually decreases. In this way, the flow rate of heat transfer oil entering the convection unit can be precisely controlled according to changes in the actual heat load, thereby adjusting the intensity of heat exchange.

[0012] Preferably, an oil inlet manifold is connected to the upper part of one end of the radiant assembly, and an oil outlet manifold is connected to the upper part of the other end of the radiant assembly. The oil inlet manifold is connected to the upper heat transfer oil inlet pipe through a pipeline, and one side of the upper heat transfer oil inlet pipe is connected to the lower heat transfer oil inlet pipe through a connecting pipe.

[0013] This design features an oil inlet manifold at one end of the radiant heat exchanger connected to the upper heat transfer oil inlet pipe, allowing heat transfer oil entering from the upper part of the convection heat exchanger to flow into the radiant heat exchanger. Simultaneously, one side of the upper heat transfer oil inlet pipe is connected to the lower heat transfer oil inlet pipe via a connecting pipe. This ensures that the flow rates of the upper and lower heat transfer oil inlets influence and balance each other when the flow rate is adjusted. When the flow rate of the upper heat transfer oil inlet pipe is adjusted via a valve, a portion of the heat transfer oil can flow into the lower heat transfer oil inlet pipe through the connecting pipe, ensuring that the lower convection heat exchanger also receives a suitable flow rate of heat transfer oil, maintaining the stable operation of the entire heat exchange system. The oil outlet manifold at the other end of the radiant heat exchanger collects the heat transfer oil after radiant heat exchange and transports it to subsequent heat-using stages.

[0014] Preferably, a fire barrier is installed on the upper half of the connection port between the radiation group and the convection group.

[0015] This feature involves installing a firewall at the upper part of the connection between the radiant and convection heat exchangers. When hot flue gas flows from the radiant heat exchanger to the convection heat exchanger, the firewall prevents the high-temperature flame from directly entering the convection heat exchanger. The high-temperature flame in the radiant heat exchanger primarily transfers heat through radiation. If it were to directly enter the convection heat exchanger, it would cause localized overheating of the convection heat exchanger tubes, exceeding their design temperature. The firewall alters the flow direction of the flame and hot flue gas, allowing the hot flue gas to enter the convection heat exchanger at a more uniform speed and temperature, thus preventing localized overheating of the convection heat exchanger tubes.

[0016] Preferably, a vertical smoke deflector is installed in the middle of the convection group, and a smoke inlet is provided at the upper part of the smoke deflector.

[0017] The vertical baffle plate installed in the middle of the flow group alters the flow path of the hot flue gas within the convection group. Originally flowing in a straight line, the hot flue gas is forced to change direction upon encountering the baffle plate, flowing upwards through the inlet before continuing downwards, creating a tortuous flow path. This tortuous flow path increases the contact time and area between the hot flue gas and the convection heat exchange tubes, thus enhancing the convective heat transfer process.

[0018] Preferably, a ladder is installed on the outside of the housing.

[0019] This feature includes an external ladder installed on the boiler shell, providing convenient access for workers to safely and easily reach various parts of the boiler, such as the top and sides, facilitating routine inspections, maintenance, cleaning, and equipment debugging. The ladder's design conforms to ergonomics and safety standards, ensuring stability and safety for workers during the climbing process.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In this gasifier organic heat carrier boiler structure, the radiant heat exchange tubes are arranged in a ring on the inner wall of the shell, while the convection heat exchange tubes are arranged in a serpentine pattern. Together, they form a highly efficient composite heat exchange system, extending the residence time of the flue gas within the shell and allowing the heat carried by the flue gas to be fully transferred to the heat transfer oil, significantly improving heat exchange efficiency and reducing energy waste. Secondly, the convection group is configured with upper and lower sets, respectively connected to the upper and lower heat transfer oil inlet pipes. These are connected by a connecting pipe with valves installed at the ends, allowing for flexible adjustment of the heat transfer oil flow rate and direction to meet the heat requirements under different operating conditions. The design improves the flexibility and adaptability of boiler operation. Furthermore, the fire-resistant wall at the connection between the radiant and convection heat exchangers effectively prevents flames from directly entering the convection heat exchanger, avoiding damage to the convection heat exchange tubes due to localized high temperatures and ensuring safe and stable equipment operation. Simultaneously, the baffle plate in the middle of the convection heat exchanger alters the flue gas flow path, further enhancing the convection heat transfer effect and improving the waste heat recovery rate. Finally, the ladder on the outside of the shell facilitates daily inspection and maintenance by staff, and the solid support of the foundation for the radiant and convection heat exchangers enhances the overall structural stability of the boiler and extends the service life of the equipment.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a gasifier organic heat carrier boiler structure, such as... Figure 1 As shown, the device includes a shell, inside which a radiation group 2 and a convection group 4 are arranged. One end of the radiation group 2 is connected to the convection group 4, and the other end of the radiation group 2 is provided with a flue gas inlet 21. The end of the convection group 4 away from the radiation group 2 is provided with a flue gas outlet 44. The radiation group 2 includes radiation heat exchange tubes distributed in a ring on the inner wall of the shell, and the convection group 4 includes convection heat exchange tubes arranged in a serpentine pattern inside the shell.

[0030] A radiation heat exchange group 2 and a convection heat exchange group 4 are arranged inside the shell. One end of the radiation heat exchange group 2 is connected to the flue gas inlet 21, and the other end is connected to the convection heat exchange group 4. The end of the convection heat exchange group 4 furthest from the radiation heat exchange group 2 is the flue gas outlet 44. The radiant heat exchange tubes of the radiation heat exchange group 2 are distributed in a ring on the inner wall of the shell, and the radiant heat exchange tubes absorb heat by utilizing the radiant heat transfer of the high-temperature flue gas. The convection heat exchange tubes of the convection heat exchange group 4 are arranged in a serpentine pattern inside the shell, and the heat is transferred to the convection heat exchange tubes through forced convection between the hot flue gas and the convection heat exchange tubes. The hot flue gas enters the radiation heat exchange group 2 from the flue gas inlet 21, enters the convection heat exchange group 4 after radiant heat exchange, and finally exits from the flue gas outlet 44. During this process, heat is continuously transferred to the heat transfer oil. The synergistic work of the radiation heat exchange group 2 and the convection heat exchange group 4 constructs a composite heat exchange system, which greatly extends the travel and residence time of the hot flue gas in the shell, promotes full contact between the hot flue gas and the heat exchange tubes, significantly improves the heat exchange efficiency, effectively reduces energy waste, and improves energy utilization. Meanwhile, the annularly distributed radiative heat exchange tubes and the serpentinely arranged convective heat exchange tubes increase the heat exchange area and further enhance the heat exchange effect.

[0031] In this embodiment, as Figure 1 As shown, the bottoms of radiation group 2 and convection group 4 are supported by foundation 1.

[0032] Foundation 1 provides stable support for the radiant coil 2 and the convection coil 4, ensuring the entire boiler structure remains stable on the ground. Foundation 1 can bear the weight of the radiant coil 2, the convection coil 4, and the internal medium, evenly distributing gravity across the ground and preventing the equipment from sinking or tilting due to excessive localized stress. This keeps the boiler stable during operation, avoiding the impact of shaking or displacement on the internal structure and heat exchange process, extending the service life of the equipment, improving operational safety, reducing potential safety hazards caused by structural instability, and ensuring continuous production.

[0033] Specifically, such as Figure 1 , Figure 3 As shown, the convection group 4 includes upper and lower groups. The bottom of the upper convection group 4 is connected to the upper heat transfer oil inlet pipe 41, and the bottom of the lower convection group 4 is connected to the lower heat transfer oil inlet pipe 42.

[0034] The convection group 4 is divided into upper and lower groups. The bottom of the upper convection group 4 is connected to the upper heat transfer oil inlet pipe 41, and the bottom of the lower convection group 4 is connected to the lower heat transfer oil inlet pipe 42. The heat transfer oil enters the convection group 4 through the lower heat transfer oil inlet pipe 42 and the upper heat transfer oil inlet pipe 41. This design allows the heat transfer oil to exchange heat in the upper and lower convection groups 4 separately, forming different circulation paths. In actual operation, the flow rate of the heat transfer oil entering the upper and lower convection groups 4 can be flexibly adjusted according to different operating conditions, achieving precise control of the heat exchange process. This improves the flexibility and adaptability of boiler operation. For different production process requirements, such as conditions requiring rapid heating or maintaining a specific temperature, the flow rate of the heat transfer oil inlet pipes 41 and 42 can be adjusted to meet different heat demands, improve energy utilization efficiency, avoid unnecessary energy consumption, and enhance the energy management level of the entire production process.

[0035] Furthermore, such as Figure 1 As shown, valves 5 are installed at the ends of the upper heat transfer oil inlet pipe 41 and the lower heat transfer oil inlet pipe 42.

[0036] Valve 5 is installed at the ends of the upper heat transfer oil inlet pipe 41 and the lower heat transfer oil inlet pipe 42. By controlling the opening of valve 5, the flow rate of heat transfer oil can be adjusted. When valve 5 is fully open, the heat transfer oil flow rate is at its maximum; as valve 5 is gradually closed, the heat transfer oil flow rate gradually decreases. In this way, the flow rate of heat transfer oil entering the convection group 4 can be precisely controlled according to changes in the actual heat load, thereby adjusting the intensity of heat exchange. This achieves precise adjustment of the heat transfer oil flow rate, further enhancing the flexibility and controllability of boiler operation. Operators can quickly adjust the heat transfer oil flow rate according to real-time needs during production, ensuring a precise match between the boiler's output heat and actual heat demand, avoiding production problems caused by insufficient or excessive heat supply, and improving the stability of the production process and product quality.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 4 As shown, an oil inlet manifold 22 is connected to the upper part of one end of the radiant group 2, and an oil outlet manifold 23 is connected to the upper part of the other end of the radiant group 2. The oil inlet manifold 22 is connected to the upper heat transfer oil inlet pipe 41 through a pipeline, and one side of the upper heat transfer oil inlet pipe 41 is connected to the lower heat transfer oil inlet pipe 42 through a connecting pipe 7.

[0038] The oil inlet manifold 22 at one end of the radiant group 2 is connected to the upper heat transfer oil inlet pipe 41 via a pipeline, allowing the heat transfer oil entering from the upper part of the convection group 4 to flow into the radiant group 2. Simultaneously, one side of the upper heat transfer oil inlet pipe 41 is connected to the lower heat transfer oil inlet pipe 42 via a connecting pipe 7. This ensures that the flow rates of the upper and lower heat transfer oil inlets 41 and 42 can influence and balance each other when the heat transfer oil flow rate is adjusted. When the flow rate of the upper heat transfer oil inlet pipe 41 is adjusted via valve 5, a portion of the heat transfer oil can flow into the lower heat transfer oil inlet pipe 42 through the connecting pipe 7, ensuring that the lower convection group 4 also receives a suitable flow rate of heat transfer oil, maintaining the stable operation of the entire heat exchange system. The oil outlet manifold 23 at the other end of the radiant group 2 is used to collect the heat transfer oil after radiant heat exchange and transport it to subsequent heat-using stages. This ensures a reasonable circulation of the heat transfer oil between the radiant group 2 and the convection group 4, optimizing the workflow of the entire heat exchange system. Through the coordinated action of the inlet manifold 22, the connecting pipe 7, and the outlet manifold 23, the heat transfer oil can fully absorb the heat of the hot flue gas, further improving the heat exchange efficiency. It can also ensure the stable operation of the system under different working conditions, reduce local overheating or overcooling caused by poor circulation of the heat transfer oil, and improve the reliability and service life of the equipment.

[0039] Furthermore, such as Figure 1 As shown, a fire barrier 3 is installed on the upper half of the connection port between the radiation group 2 and the convection group 4.

[0040] A firewall 3 is installed on the upper part of the connection between the radiant group 2 and the convection group 4. When hot flue gas flows from the radiant group 2 to the convection group 4, the firewall 3 can prevent high-temperature flames from directly entering the convection group 4. The high-temperature flames in the radiant group 2 mainly transfer heat through radiation. If they directly enter the convection group 4, the convection heat exchange tubes will be locally overheated, exceeding their design temperature. The firewall 3 changes the flow direction of the flame and hot flue gas, allowing the hot flue gas to enter the convection group 4 at a more uniform speed and temperature, avoiding localized overheating of the convection heat exchange tubes. This effectively protects the convection heat exchange tubes of the convection group 4, preventing damage due to localized high temperatures, extending the service life of the convection heat exchange tubes, improving the overall safety and stability of the equipment, reducing downtime for maintenance due to equipment failure, ensuring production continuity, and reducing production and operating costs.

[0041] Furthermore, such as Figure 1 As shown, a vertical smoke deflector 43 is installed in the middle of the convection group 4, and a flue gas inlet is provided at the upper part of the smoke deflector 43.

[0042] The vertical baffle plate 43 installed in the middle of the convection group 4 alters the flow path of the hot flue gas within the convection group 4. Originally flowing in a straight line, the hot flue gas is forced to change direction upon encountering the baffle plate 43, flowing upwards through the inlet and then continuing downwards, forming a tortuous flow path. This tortuous flow path increases the contact time and area between the hot flue gas and the convection heat exchange tubes, enhancing the convective heat transfer process. This further improves the convective heat transfer effect, allowing for more efficient utilization of the waste heat in the hot flue gas, increasing the waste heat recovery rate, reducing energy waste, improving the overall energy efficiency of the boiler system, and reducing the demand for external energy, resulting in significant energy-saving benefits.

[0043] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, a ladder 6 is installed on the outside of the shell.

[0044] A ladder 6 is installed on the outside of the boiler shell, providing convenient access for workers to safely and easily reach various parts of the boiler, such as the top and sides, facilitating routine inspections, maintenance, cleaning, and equipment debugging. The ladder 6 is designed in accordance with ergonomics and safety regulations, ensuring stability and safety for workers during climbing. This greatly facilitates boiler maintenance and repair, improves efficiency, and reduces worker workload and risks. Regular maintenance and inspections allow for the timely detection and resolution of potential equipment problems, ensuring the boiler remains in good operating condition, extending equipment lifespan, and guaranteeing safe and stable production.

[0045] In operation, the gasifier-organic heat carrier boiler structure of this utility model first introduces high-temperature hot flue gas into the boiler through the flue gas inlet 21 of the radiant assembly 2. The radiant heat exchange tubes, arranged in a ring along the inner wall of the shell within the radiant assembly 2, absorb the radiant heat from the hot flue gas using the principle of radiant heat transfer. During this stage, a portion of the heat from the hot flue gas is transferred to the radiant heat exchange tubes via radiation, achieving the initial heat exchange.

[0046] After radiative heat exchange, the hot flue gas enters convection group 4 through the connection between radiative group 2 and convection group 4. The serpentine arrangement of convection heat exchange tubes within convection group 4 further absorbs heat from the hot flue gas through forced convection. The hot flue gas flows along a serpentine path within convection group 4, making full contact with the convection heat exchange tubes. Under the action of the baffle plate 43, the flow path of the hot flue gas is tortuous, increasing the contact time and area with the convection heat exchange tubes, enhancing the convection heat exchange effect, until finally discharged from the flue gas outlet 44.

[0047] The heat transfer oil enters the upper convection group 4 through the upper heat transfer oil inlet pipe 41 at the bottom and the lower heat transfer oil inlet pipe 42 at the bottom of the lower convection group 4. In the convection group 4, the heat transfer oil absorbs heat transferred by the convection heat exchange tubes, achieving initial heating. Subsequently, through the connection between the upper heat transfer oil inlet pipe 41 and the oil inlet manifold 22, the heat transfer oil flows into the radiation group 2, where it further absorbs heat transferred by the radiation heat exchange tubes, achieving secondary heating. The opening of the regulating valve 5 controls the flow rate of the heat transfer oil, and through the connecting pipe 7, the flow rates of the upper and lower heat transfer oil inlets 41 and 42 can be balanced and regulated to ensure that the lower convection group 4 also receives a suitable flow rate of heat transfer oil. Finally, the heat transfer oil, after being fully heated by the radiation group 2, flows out from the oil outlet manifold 23 and is transported to subsequent heat-using stages.

[0048] The foundation 1 provides stable support for the radiant heat exchanger 2 and the convection heat exchanger 4, ensuring the boiler remains stable during operation and preventing the heat exchange process from being affected by shaking. The fire wall 3 at the connection between the radiant heat exchanger 2 and the convection heat exchanger 4 prevents high-temperature flames from directly entering the convection heat exchanger 4, preventing local overheating damage to the convection heat exchange tubes. The ladder 6 on the outside of the shell facilitates daily inspection and maintenance by staff, ensuring the long-term stable operation of the equipment.
