Description

Technical Field

[0001] This utility model belongs to the field of waste heat boiler technology and relates to an adaptive steam pressure regulation device for a copper smelting waste heat boiler. Background Technology

[0002] Waste heat boilers are boilers that use the waste heat from waste gas, waste materials or waste liquid in various industrial processes and the heat generated after the combustion of combustible substances to heat water to a certain temperature. Through waste heat recovery, they can produce hot water or steam to supply other processes.

[0003] A copper smelting waste heat boiler utilizes the waste heat generated during the copper smelting process for heating, and its working principle is the same as other waste heat boilers. During operation, the generated steam is introduced into the boiler drum. Therefore, the drum typically contains high-temperature, high-pressure steam. To prevent steam leakage, the drum employs a sealed structure. Consequently, when the steam pressure becomes too high, the steam inside the drum needs to be released to prevent damage to the drum and potential explosions or other safety accidents. Simultaneously, due to the high temperature of the steam inside the drum, the released steam creates a high-temperature zone around the drum, potentially posing a risk of burns to workers.

[0004] Therefore, it is necessary to provide an adaptive steam pressure regulation device for waste heat boilers in copper smelting, which can automatically discharge steam when the steam pressure inside the boiler drum is too high, while preventing steam from escaping into the air and forming a high-temperature area, thus avoiding safety hazards such as burns. Utility Model Content

[0005] To overcome the problems in the prior art, this invention uses a pressure sensor to measure the steam pressure inside the boiler drum in real time and transmits the measurement result signal to the control system. Upon receiving the signal, the control system compares the measurement result with a preset threshold. If the measurement result is greater than the preset threshold, the control system determines that the steam pressure inside the boiler drum is too high and controls the electric valve to open for pressure relief. During the pressure relief process, the pressure sensor continues to transmit the measurement result signal to the control system in real time. Upon receiving the signal, the control system determines that the steam pressure inside the boiler drum is below the threshold and controls the electric valve to close, thus maintaining the steam pressure inside the boiler drum within a safe range. Simultaneously, the steam discharged during the pressure relief process directly enters the cooling component for cooling instead of escaping into the air, effectively reducing the risk of burns.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the contents described herein.

[0027] like Figure 1-3 As shown, the adaptive steam pressure regulation device for the waste heat boiler in copper smelting includes a boiler drum 1, a pressure sensor 2, a first pressure relief pipe 3, an electric valve 4, a cooling component 5, and a base 6. The cooling component 5 is fixedly installed on the base 6, and the boiler drum 1 is placed horizontally on the cooling component 5. The pressure sensor 2 is installed on the side wall of the boiler drum 1 to measure the internal pressure of the boiler drum 1. One end of the first pressure relief pipe 3 is connected to one end of the boiler drum 1, and the other end of the first pressure relief pipe 3 is connected to the cooling component 5. An electric valve 4 is installed on the first pressure relief pipe 3.

[0028] The air pressure sensor 2 is communicatively connected to the control system, and the electric valve 4 is communicatively connected to the control system.

[0029] When the waste heat boiler in copper smelting is operating normally, steam continuously enters the boiler drum 1. Although the function of the waste heat boiler is to supply steam to other processes (steam output from the boiler is a conventional technology, and the steam output components are not shown in the diagram), the boiler drum 1 is not the end point of steam flow, and steam will not accumulate indefinitely within the boiler drum 1. However, the steam flow rate into and out of the boiler drum 1 will fluctuate. Therefore, the pressure generated by the steam within the boiler drum 1 will fluctuate. Since the boiler drum 1 has a pressure-bearing limit, if the pressure generated by the steam within the boiler drum 1 is too high and exceeds the pressure-bearing limit, it will lead to damage to the boiler drum 1 and potential explosions or other safety accidents. Therefore, the pressure-bearing limit of the boiler drum 1 can be used as a preset threshold input into the control system (the pressure-bearing limit of the boiler drum 1 is usually provided by the boiler manufacturer, but the boiler user can also redetermine the preset threshold according to their own production requirements or operating procedures). During normal boiler operation, the pressure sensor 2... The pressure inside the boiler drum 1 is measured in real time, and the measurement result signal is transmitted to the control system in real time. After receiving the signal, the control system can identify the actual pressure value inside the boiler drum 1 in real time. The control system compares the actual pressure value with a preset threshold. If the actual pressure value exceeds the preset threshold, the control system controls the electric valve 4 to open. The steam inside the boiler drum 1 can be discharged through the first pressure relief pipe 3 and enter the cooling component 5. The amount of steam inside the boiler drum 1 decreases, and the pressure decreases. During this process, the pressure sensor 2 continuously measures the pressure inside the boiler drum 1 in real time and transmits the measurement result signal to the control system. The control system can identify the pressure change inside the boiler drum 1 in real time during the pressure relief process. As the pressure relief proceeds, the pressure inside the boiler drum 1 continues to decrease. When the control system compares the pressure value inside the boiler drum 1 with the preset threshold and the pressure value inside the boiler drum 1 is less than the preset threshold, it proves that the steam pressure inside the boiler drum 1 is within the normal range. Then, the control system controls the electric valve 4 to close.

[0030] During the depressurization process, the steam inside the boiler drum 1 enters the cooling component 5 through the first depressurization pipe 3 and is not directly discharged into the air. This prevents the air temperature around the boiler drum 1 from rising rapidly, thereby reducing or avoiding the probability of workers being scalded by the steam released during depressurization.

[0031] To further reduce the mutual temperature influence between the cooling component 5 and the boiler drum 1, a heat insulation layer can be installed between the boiler drum 1 and the cooling component 5.

[0032] The cooling component 5 includes a vertical heat-conducting copper plate 501 and a horizontal heat-conducting copper plate 502. The vertical heat-conducting copper plate 501 is fixedly installed on the horizontal heat-conducting copper plate 502, and cavities are opened in both the vertical heat-conducting copper plate 501 and the horizontal heat-conducting copper plate 502. The first pressure relief pipe 3 is connected to the cavity of the vertical heat-conducting copper plate 501. The horizontal heat-conducting copper plate 502 is fixedly installed on the base 6, and a drain outlet 14 is opened on the bottom surface of the horizontal heat-conducting copper plate 502. The drain outlet 14 is sealed by a plug.

[0033] The vertical heat-conducting copper plates 501 are several pieces, and the vertical heat-conducting copper plates 501 are parallel to each other and perpendicular to the axis of the pot drum 1. The first pressure relief pipe 3 is connected to the cavity of the nearest vertical heat-conducting copper plate 501.

[0034] During the pressure relief process, the steam discharged through the first pressure relief pipe 3 enters the cavity of the vertical heat-conducting copper plate 501. Since the cavity of the vertical heat-conducting copper plate 501 is connected to the cavity of the horizontal heat-conducting copper plate 502, the steam will diffuse in the cavity of the vertical heat-conducting copper plate 501 and flow into the cavity of the horizontal heat-conducting copper plate 502. When the steam enters the cavity, it will come into contact with the lower-temperature heat-conducting copper plate, thereby exchanging heat. The steam temperature drops rapidly and condenses into water, while the temperature of the heat-conducting copper plate rises. At the same time, the heat-conducting copper plate dissipates heat, but the heat dissipation rate of the heat-conducting copper plate is relatively slow. Compared to directly venting steam, the air temperature around the heat-conducting copper plate rises slowly. The airflow around the heat-conducting copper plate further reduces the upper limit of the temperature rise. Compared to directly contacting the vented high-temperature steam, the temperature rise of the surrounding air caused by the heat dissipation of the heat-conducting copper plate is smaller in scope and slower in rate and degree. As long as operators do not directly contact the heat-conducting copper plate, they will not be burned. Therefore, directing the depressurized steam into the cavity of the heat-conducting copper plate can reduce or avoid the risk of personnel being burned by steam.

[0035] Setting up several vertical heat-conducting copper plates 501 can effectively increase the copper plate area in a small space, making it easier for steam to diffuse and come into contact with more heat-conducting copper plates, thereby improving cooling efficiency.

[0036] The cooling component 5 also includes a connecting pipe 7, which is provided between two adjacent vertical heat-conducting copper plates 501, and the connecting pipe 7 connects the cavities of the two adjacent vertical heat-conducting copper plates 501.

[0037] The connecting pipe 7 provides more flow paths for steam. Steam can flow through the connecting pipe 7 to the cavities of different vertical heat-conducting copper plates 501, and then to different positions of the horizontal heat-conducting copper plate 502, effectively improving the steam flow efficiency. This makes it easier for steam to enter the cavities of different vertical heat-conducting copper plates 501 and to contact and exchange heat with more heat-conducting copper plates with lower temperatures, thereby improving the steam cooling efficiency.

[0038] After steam enters the cavity of the heat-conducting copper plate for heat exchange, the steam temperature decreases and condenses into water. As the device is used for a longer period of time, the amount of water accumulated in the cavity of the heat-conducting copper plate will also increase. The water in the cavity can be drained out of the drain port 14 by pulling out the plug. During normal operation, the plug blocks the drain port 14 to prevent steam from escaping from the drain port 14.

[0039] The adaptive steam pressure regulation device for the waste heat boiler in copper smelting also includes a gas collecting hood 8, a pressure relief valve 9, and a second pressure relief pipe 10. The gas collecting hood 8 is fixedly installed at one end of the boiler drum 1 opposite to the first pressure relief pipe 3. An installation hole is opened on one end of the boiler drum 1 located inside the gas collecting hood 8. The pressure relief valve 9 is installed at the installation hole. One end of the second pressure relief pipe 10 is connected to the gas collecting hood 8, and the other end of the second pressure relief pipe 10 is connected to the cavity of the nearest vertical heat-conducting copper plate 501.

[0040] The pressure relief valve 9 includes a mounting block 901, a piston 902, and a spring 903. The mounting block 901 is fixedly installed in the mounting hole, and a mounting groove is provided on the mounting block 901. The piston is slidably disposed in the mounting groove. The spring 903 is sleeved on the piston 902, and one end of the spring 903 is fixedly connected to the bottom of the piston 902, and the other end of the spring 903 is fixedly connected to the mounting block 901. A hollow cavity 904 surrounding the mounting groove is also provided in the mounting block 901. A vent hole 905 connecting the hollow cavity 904 and the gas collection hood 8 is provided on the side wall of the hollow cavity 904. A connecting hole 906 connecting the mounting groove and the hollow cavity 904 is provided on the inner side wall of the hollow cavity 904. The connecting hole 906 is adjacent to the bottom surface of the piston 902.

[0041] During normal use, the pressure is mainly released by controlling the electric valve 4 to open through the control system. However, if an accidental abnormality occurs, the steam pressure inside the boiler drum 1 may surge. At this time, the steam inside the boiler drum 1 will push the piston 902 outward, and the spring 903 will be compressed. During normal operation, the piston 902 seals the boiler drum 1, and the steam inside the boiler drum 1 is blocked by the piston 902 and cannot reach the location of the connecting hole 906. When the piston 902 is pushed out by the steam, the bottom surface of the piston 902 moves outward, and the piston 902 loses its blocking effect. The steam flows through the connecting hole 906 into the hollow cavity 904 of the mounting block 901, and then is discharged into the gas collection hood 8 through the steam vent 905. It then enters the cavity of the vertical heat-conducting copper plate 501 through the second pressure relief pipe 10 for cooling.

[0042] The adaptive steam pressure regulation device for the waste heat boiler in copper smelting also includes a flue gas pipeline group. The flue gas pipeline group passes through the boiler drum 1, and its two ends are connected to the inlet pipe 12 and the outlet pipe 13, respectively. The inlet pipe 12 and the outlet pipe 13 are horizontally fixed on the base 6 and are both located outside the cooling component 5. The inlet pipe 12 and the outlet pipe 13 are both parallel to the axis of the boiler drum 1.

[0043] The flue gas duct group consists of several unit flue gas ducts 11, which are evenly distributed along the axial direction of the boiler drum 1 and are perpendicular to the axis of the boiler drum 1.

[0044] The high-temperature flue gas generated during copper smelting can not only heat water to form high-temperature steam, which is then introduced into the boiler drum 1, but also be introduced into the flue gas pipeline group through the flue gas inlet pipe 12. During the process of transporting steam from the boiler drum 1 into the boiler drum 1, heat loss is likely to occur. Therefore, after the high-temperature flue gas from copper smelting enters the flue gas pipeline group, since the flue gas pipeline group passes through the boiler drum 1, the high-temperature flue gas from copper smelting in the flue gas pipeline group can heat the steam in the boiler drum 1 to compensate for the heat loss during the steam transport process.

[0045] High-temperature flue gas from copper smelting is input through the inlet pipe 12 and enters the flue gas pipeline group through the inlet pipe 12. Then it continues to move into the outlet pipe 13, where the copper smelting flue gas undergoes routine transportation and treatment.

[0046] A steam inlet pipe 15 is provided on the boiler drum 1, and the steam inlet pipe 15 and the first pressure relief pipe 3 are located at the same end of the boiler drum 1.

[0047] Steam from the waste heat boiler is fed into the boiler drum 1 through the steam inlet pipe 15.

[0048] In this invention, in order to ensure the sealing of the boiler drum 1 and prevent steam leakage from the boiler drum 1, conventional sealing treatment is performed at the installation position of the pressure sensor 2 and at the position where the flue gas duct group passes through the boiler drum 1.

[0049] The working process of this utility model is as follows: During normal operation of the boiler, steam enters the boiler drum through the steam inlet pipe. The pressure sensor measures the steam pressure inside the boiler drum in real time and transmits the signal to the control system in real time. The control system receives the signal and identifies the real-time steam pressure value inside the boiler drum. It compares the pressure value with a preset threshold to determine whether the pressure value inside the boiler drum exceeds the safe range. If it exceeds the safe range, the control system controls the electric valve to open to release pressure. When the pressure inside the boiler drum returns to the safe range, the control system controls the electric valve to close. The released steam is introduced into the cooling component through the first pressure relief pipe for cooling. When the steam pressure inside the boiler drum experiences an abnormal surge, the piston is pushed open, and the pressure relief valve participates in the pressure relief, further improving the safety of boiler operation.

[0050] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and in detail without departing from the scope defined by the claims of this utility model.
