Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler technology, and in particular to an adaptive temperature regulation device for thermal power plant boilers. Background Technology
[0002] A thermal power plant boiler is an energy conversion device whose main function is to heat feedwater by burning fuels (such as coal and oil) to produce high-temperature, high-pressure steam. This steam is then used to drive a steam turbine to generate electricity. The boiler is one of the core pieces of equipment in a thermal power plant, responsible for converting the chemical energy of fuel into thermal energy to produce steam for power generation. Existing boiler temperature control measures cannot effectively self-adapt to the internal temperature of the boiler, requiring manual adjustment by operators. Furthermore, the temperature adjustment rate is slow. Excessive or insufficient internal temperature can severely impact the equipment. Excessive temperature can cause additional thermal stress on internal components, accelerating the creep rate of metal materials and potentially leading to equipment damage or even tube rupture. In contrast, insufficient temperature can exacerbate blade erosion, increase axial thrust, and potentially cause turbine instability or even shutdown. Therefore, this application proposes a thermal power plant boiler temperature adaptive control device. Utility Model Content

[0024] like Figure 1As shown, the present invention proposes a temperature adaptive regulation device for a thermal power plant boiler, comprising an outer regulating frame 1 and a frame mechanism fixed to the inner wall of the outer regulating frame 1. The frame mechanism includes fixing blocks 3 fixed to both ends of multiple outer regulating frames 1. An inner frame 5 is fixedly connected to the outer wall of multiple fixing blocks 3 away from the outer regulating frame 1, and the multiple fixing blocks 3 are fixedly connected to each other by fastening rods 4. The fixing blocks 3 play a key role in connecting the outer regulating frame 1 and the inner frame 5, ensuring a stable connection between the two. The fastening rods 4 further enhance the connection strength between the multiple fixing blocks 3, maintain the stability of the entire frame structure, and ensure that the inner frame 5 can stably perform its function during device operation. It protects the boiler-related components internally and works in conjunction with the outer regulating frame 1 externally. The inner frame 5 provides a relatively enclosed installation space for the internal temperature regulation mechanism and boiler-related components, which helps to centrally manage heat and efficiently regulate temperature.
[0025] In addition, such as Figure 1 , Figure 3 and Figure 4 As shown, a temperature regulation mechanism is provided between multiple outer adjustment frames 1 and inner frame 5. The temperature regulation mechanism includes internal cooling pipes 6 fixed between the outer adjustment frames 1 and inner frame 5. Conducting pipes 7 are fixedly connected to the outer walls of multiple internal cooling pipes 6. When the operating temperature of the thermal power plant boiler is too high, the cooling liquid circulates in the internal cooling pipes 6, using the specific heat capacity of the liquid to absorb the excess heat emitted by the boiler. As the main heat exchange component, the internal cooling pipes 6 have a large area of pipe wall located inside the inner frame 5, which allows the heat transferred from the internal boiler to fully contact the internal cooling pipes 6, achieving efficient heat transfer. The bottom ends of multiple conducting pipes 7 are fixedly connected to bottom transmission ports 8. The conducting pipes 7 are responsible for transferring the cooling liquid after absorbing heat in the internal cooling pipes 6 to the bottom transmission ports 8. The bottom transmission ports 8 are the key nodes for the cooling liquid to flow out of the temperature regulation mechanism, providing an outlet for subsequent cooling liquid circulation.
[0026] It should be added that, such as Figure 2 , Figure 3 and Figure 4As shown, multiple heating rods 2 are fixedly connected to the outer walls of multiple external heating frames 1. Electric heating wires 13 are fixedly connected to the outer walls of multiple heating rods 2. Multiple heating rods 2 pass through the gaps between the internal cooling pipes 6, and one end of multiple heating rods 2 is fixedly connected to an inner cavity 14. Multiple heat-conducting blocks 15 are fixedly connected to the outer wall of the inner cavity 14. The ends of multiple heat-conducting blocks 15 away from the inner cavity 14 are fixedly connected to the inner wall of the inner frame 5. When the boiler temperature is too low, affecting normal operating efficiency or causing incomplete combustion, the heating rods 2 can be activated. The electric heating wires 13 are energized and heated, generating a large amount of heat using the Joule heating effect. The heat generated by the electric heating wires 13 is quickly transferred to the inner cavity 14 through the heating rods 2. The heat is then efficiently transferred to the boiler through the heat-conducting blocks 15 outside the inner cavity 14, thereby increasing the boiler temperature. The temperature around the inner frame 5 is increased through the multiple heat-conducting blocks 15, thus heating the boiler in all directions and avoiding localized low temperatures that could affect boiler operation and cause cracks.
[0027] And, as Figure 1 , Figure 2 and Figure 4 As shown, a transmission mechanism is provided on one side of multiple external adjustment frames 1. The transmission mechanism includes a transmission pipe 9 fixed to the bottom end of multiple bottom transmission ports 8, and an extension pipe 10 is fixedly connected to one side of the outer wall of the transmission pipe 9. The end of the extension pipe 10 away from the transmission pipe 9 is fixedly connected to the input end of the transmission pump 11. An input pipe 12 is fixedly connected to the output end of the transmission pump 11. The end of the input pipe 12 away from the transmission pump 11 is fixedly connected to the bottom end of the liquid storage tank 19. An output pipe 20 is fixedly connected to the top end of the liquid storage tank 19. The end of the output pipe 20 away from the liquid storage tank 19 is fixedly connected to the bottom end of the liquid storage tank 19. The cooling liquid is connected to the top of the internal cooling pipe 6 and, together with the transmission pipe 9 and extension pipe 10, forms a transmission channel for the cooling liquid. The cooling liquid, having absorbed heat, flowing from the bottom transmission port 8, is transported to the transmission pump 11. The transmission pump 11 pressurizes the cooling liquid and delivers it to the input pipe 12. The input pipe 12 then delivers the pressurized cooling liquid from the transmission pump 11 to the storage tank 19. The storage tank 19 stores and buffers the cooling liquid, ensuring a stable supply and preventing fluctuations during transmission from affecting the temperature regulation effect. The output pipe 20 then returns the cooling liquid from the storage tank 19 to the top of the internal cooling pipe 6, achieving the recycling of the cooling liquid and continuously cooling the boiler.
[0028] It should be noted that, as Figure 1 , Figure 3 and Figure 4As shown, a temperature measuring port 16 extends through one side of the inner wall of the inner cavity 14. A mounting bracket 17 is fixedly connected to one side of the outer wall of the temperature measuring port 16, and a display meter 18 is fixedly connected to the top of the mounting bracket 17. A high-precision temperature sensor (WSSX-411 bimetallic thermometer) is built into the temperature measuring port 16 to monitor the temperature changes of the inner cavity 14 in real time and convert the temperature signal into an electrical signal, which is then transmitted to the display meter 18. The mounting bracket 17 securely mounts the temperature measuring port 16 and the display meter 18, ensuring their normal operation in complex working environments. The display meter 18 presents the received temperature signal to the operator in an intuitive numerical or graphical format, allowing the operator to easily monitor the internal temperature of the boiler and automatically adjust the temperature.
[0029] In this embodiment: the fixing block 3 plays a key role in connecting the outer adjustment frame 1 and the inner frame 5, and the fastening rod 4 further enhances the connection strength between the multiple fixing blocks 3. The inner frame 5 and the outer adjustment frame 1 work together. The inner frame 5 provides a relatively enclosed installation space for the internal temperature regulation mechanism and related boiler components, which helps to centrally manage heat and efficiently regulate temperature. When the operating temperature of the thermal power plant boiler is too high, the cooling liquid circulates in the internal cooling pipe 6. The internal cooling pipe 6 ensures that the heat transferred from the internal boiler is in full contact with the internal cooling pipe 6, achieving efficient heat transfer. The conduction pipe 7 is responsible for transferring the cooling liquid that has absorbed heat in the internal cooling pipe 6 to the bottom transmission port 8. The bottom transmission port 8 is the key node for the cooling liquid to flow out of the temperature regulation mechanism. To provide an outlet for subsequent cooling liquid circulation, when the boiler temperature is too low, affecting normal operating efficiency or causing incomplete combustion, the heating rod 2 can be activated. The electric heating wire 13 is energized and heats up, generating a large amount of heat using the Joule heating effect. The heating rod 2 quickly transfers the heat generated by the electric heating wire 13 to the inner cavity 14, and then efficiently transfers the heat to the boiler through the heat-conducting block 15 outside the inner cavity 14, thereby increasing the boiler temperature. Multiple heat-conducting blocks 15 raise the temperature around the inner frame 5, thus heating the boiler from all directions. A high-precision temperature sensor, model WSSX-411 bimetallic thermometer, is built into the temperature measuring port 16 to monitor the temperature change of the inner cavity 14 in real time and convert the temperature signal into an electrical signal to be transmitted to the display table 18.
[0030] The above specific embodiments are merely several optional embodiments of this utility model.
