Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery boiler technology, and in particular to an active calcium carbide waste heat gas-cooled power generation waste heat boiler. Background Technology

[0002] During calcium carbide production, a large amount of waste heat carrying high heat is generated. The recovery and utilization of this waste heat is a key aspect of energy conservation and emission reduction, and waste heat boilers are the core equipment in gas-cooled power generation waste heat recovery systems. However, in practical applications, existing waste heat boilers for gas-cooled power generation using calcium carbide waste heat often employ a simple tubular design for the waste heat intake structure. This leads to the introduced waste heat airflow concentrating and impacting localized areas of the heat exchange components, resulting in uneven heat exchange and insufficient contact between the waste heat and the heat exchange components, affecting heat exchange efficiency. Simultaneously, the poor compatibility between the cooling medium flow path and the heat exchange components hinders heat transfer, restricting the waste heat recovery effect. Furthermore, the waste heat retained inside the boiler is difficult to dissipate quickly, easily causing localized overheating, which not only further reduces heat exchange efficiency but may also affect the equipment's service life. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that "the waste heat intake structure is mostly a simple tubular design, which easily concentrates the waste heat airflow and impacts local areas of the heat exchange components, resulting in uneven heat exchange and insufficient contact between waste heat and heat exchange components, affecting heat exchange efficiency; at the same time, the cooling medium flow path is poorly adapted to the heat exchange components, resulting in poor heat transfer and restricting the waste heat recovery effect; in addition, the waste heat retained inside the boiler is difficult to discharge quickly, which can easily cause local overheating, further reducing heat exchange efficiency and potentially affecting the service life of the equipment." Therefore, this invention proposes an active waste heat exhaust gas-cooled power generation waste heat boiler.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An active waste heat boiler for gas-cooled power generation from calcium carbide includes: a boiler body, wherein the boiler body is provided with a waste heat inlet component for introducing waste heat from calcium carbide, and the waste heat inlet component is connected to the internal cavity of the boiler body. A heat exchange component for heat exchange is fixedly installed inside the internal cavity of the boiler body, and a cooling component for the flow of air-cooled medium is provided on the side of the heat exchange component. The boiler body is also connected to an active heat exhaust component for actively discharging internal residual heat. The active heat exhaust component is connected to the internal cavity of the boiler body. A support frame is fixedly installed on the inner wall of the internal cavity of the boiler body. A sealing element is installed at the splicing joint of the boiler body.

[0005] As a preferred embodiment of the active calcium carbide waste heat gas-cooled power generation waste heat boiler of this utility model, the waste heat intake component includes a waste heat intake pipe and an airflow diffuser. One end of the waste heat intake pipe penetrates the wall of the boiler body and extends to the outside for connecting to the calcium carbide waste heat conveying pipeline, and the other end extends to the internal cavity of the boiler body. The airflow diffuser is fixedly installed at one end of the waste heat intake pipe located in the internal cavity, facing the heat exchange component, for guiding the waste heat airflow to flow evenly to the heat exchange component.

[0006] As a preferred embodiment of the active calcium carbide waste heat gas-cooled power generation waste heat boiler of this utility model, wherein: the arrangement direction of the heat exchange components is adapted to the flow direction of the calcium carbide waste heat introduced by the waste heat inlet components inside the boiler body; the cooling components include a cooling plate, an inlet pipe and an outlet pipe; the cooling plate is attached to the outer wall of the heat exchange components; the inlet pipe and the outlet pipe respectively penetrate the wall of the boiler body and extend to the outside, and are both connected to the internal flow channel of the cooling plate.

[0007] As a preferred embodiment of the active heat exhaust gas-cooled power generation waste heat boiler of the present invention, the active heat exhaust component includes a heat exhaust pipe and an external heat exhaust fan. One end of the heat exhaust pipe is connected to the internal cavity of the boiler body, and the other end is fixedly connected to the air inlet of the heat exhaust fan. The air outlet of the heat exhaust fan faces the preset heat exhaust area and is used to actively extract the residual waste heat inside the boiler body.

[0008] As a preferred embodiment of the active calcium carbide waste heat gas-cooled power generation waste heat boiler of this utility model, the sealing element is tightly fitted to the splicing surface of the boiler body and is continuously arranged along the circumferential direction of the splicing joint to prevent waste heat leakage.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The airflow diffuser in the waste heat intake component can evenly guide the calcium carbide waste heat airflow introduced by the intake pipe to the heat exchange component, avoiding uneven heat exchange caused by concentrated airflow impact and improving the sufficient contact between waste heat and heat exchange component.

[0010] By aligning the arrangement of the heat exchange components with the direction of waste heat flow, and with the cooling plates fitted to the outer wall of the heat exchange components, the heat exchange contact area is maximized. Simultaneously, the air inlet and outlet pipes of the cooling components ensure smooth circulation of the cooling medium, quickly removing the heat absorbed by the heat exchange components and significantly improving waste heat recovery efficiency. Furthermore, the active heat exhaust components provide active heat exhaust power through exhaust fans, rapidly extracting waste heat retained inside the boiler body, preventing localized overheating caused by waste heat accumulation. This ensures the stability of heat exchange efficiency and extends the service life of the equipment. Attached Figure Description

Detailed Implementation

[0013] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] Reference Figures 1-4 An active waste heat boiler for gas-cooled power generation using calcium carbide waste heat is provided. The boiler body is 101. A waste heat inlet component 102 for introducing waste heat from calcium carbide is provided on the boiler body 101. The waste heat inlet component 102 is connected to the internal cavity of the boiler body 101. A heat exchange component 103 for heat exchange is fixedly installed in the internal cavity of the boiler body 101. A cooling component 104 for air-cooling medium circulation is provided on the side of the heat exchange component 103. An active heat exhaust component 105 for actively exhausting the internally retained waste heat is also connected to the boiler body 101. The active heat exhaust component 105 is connected to the internal cavity of the boiler body 101. A support frame 106 is fixedly installed on the inner wall of the internal cavity of the boiler body 101. A sealing element 107 is provided at the splicing joint of the boiler body 101.

[0016] The waste heat intake component 102 includes a waste heat intake pipe 1021 and an airflow diffuser 1022. One end of the waste heat intake pipe 1021 penetrates the wall of the boiler body 101 and extends to the outside for connecting to the calcium carbide waste heat conveying pipeline. The other end extends into the internal cavity of the boiler body 101. The airflow diffuser 1022 is fixedly installed at one end of the waste heat intake pipe 1021 located in the internal cavity and is arranged towards the heat exchange component 103 for guiding the waste heat airflow to flow evenly to the heat exchange component 103.

[0017] Furthermore, the arrangement direction of the heat exchange component 103 is adapted to the flow direction of the calcium carbide waste heat introduced by the waste heat intake component 102 inside the boiler body 101. The cooling component 104 includes a cooling plate 1041, an intake pipe 1042, and an outlet pipe 1043. The cooling plate 1041 is attached to the outer wall of the heat exchange component 103. The intake pipe 1042 and the outlet pipe 1043 respectively penetrate the wall of the boiler body 101 and extend to the outside, and are both connected to the internal flow channel of the cooling plate 1041. In addition, the cooling plate 1041 is filled with a cooling medium.

[0018] Furthermore, considering that the residual heat inside the boiler body can affect the heat exchange efficiency and may damage the equipment, the active heat exhaust component 105 includes a heat exhaust pipe and an external heat exhaust fan. One end of the heat exhaust pipe is connected to the internal cavity of the boiler body 101, and the other end is fixedly connected to the air inlet of the heat exhaust fan. The air outlet of the heat exhaust fan faces the preset heat exhaust area and is used to actively extract the residual heat inside the boiler body 101.

[0019] Furthermore, the sealing element 107 is tightly fitted to the splicing surface of the boiler body 101 and is continuously arranged along the circumferential direction of the splicing joint to prevent residual heat leakage. At the same time, considering that the heat exchange components are prone to displacement or deformation due to their own weight or airflow impact during long-term operation, which may lead to failure of the heat exchange structure, a support frame 106 is connected to the heat exchange component 103.

[0020] In summary, the working process of this solution is as follows: External waste heat from calcium carbide is introduced into the internal cavity of the boiler body 101 through the waste heat inlet pipe 1021 of the waste heat inlet component 102. After being evenly dispersed by the airflow diffuser 1022 at the end of the waste heat inlet pipe 1021, it flows towards the heat exchange component 103 in a preset direction. During the flow of the waste heat airflow through the heat exchange component 103, it transfers heat to the heat exchange component 103, realizing the initial heat transfer. At the same time, the air-cooling medium enters the internal flow channel of the cooling plate 1041 through the air inlet pipe 1042 of the cooling component 104. Since the cooling plate 1041 is in close contact with the outer wall of the heat exchange component 103, the air-cooling medium quickly absorbs the heat on the heat exchange component 103. The air-cooling medium with increased temperature flows out through the air outlet pipe 1043 and is transported to the air-cooled power generation equipment for waste heat recovery and utilization. During the heat exchange process, the residual waste heat inside the boiler body 101 that has not been fully exchanged is actively extracted and discharged to the preset area through the heat exhaust pipe of the active heat exhaust component 105 under the power of the heat exhaust fan.

[0021] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
