Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heat dissipation of storage tank foundations, and particularly relates to a high-temperature storage tank foundation capable of ventilation and heat dissipation. Background Art
[0002] The temperature of common high-temperature storage tanks such as molten salt storage tanks is generally between 200°C and 600°C. Even if a heat preservation and insulation layer is added to the bottom of the storage tank, a large amount of heat will still be transmitted to the foundation and the ground, generating a relatively high temperature. Temperature has a direct impact on the selection of foundation materials and structural calculations. However, since the temperature of the underground heated structure is related to various factors such as the thermal conductivity of the soil, the groundwater level, and the surface temperature distribution, and most of these factors are greatly affected by seasonal and weather changes, the heat source conditions are complex, and it is not easy to solve the boundary conditions.
[0003] To avoid damage to the bearing foundation and the ground due to heat accumulation at high temperatures, a common practice is to set up a ventilation layer between the top surface of the traditional foundation and the heat preservation and insulation layer at the bottom of the tank, that is, to arrange a certain number of ventilation pipes in a certain thickness of concrete or sand and gravel. There are generally two ventilation methods. One is to utilize the height difference between the inlet and outlet of the ventilation pipe and the air flow to form natural convection; the other is to connect each ventilation pipe with a main pipe and arrange a fan on the main pipe to achieve the effect of mechanical ventilation.
[0004] Due to the uncertainty of air temperature and wind direction, it is difficult to accurately control the effect of natural ventilation. Although mechanical ventilation can maintain the relative stability of the air flow velocity in the ventilation pipe, it cannot utilize the natural flow of air. On the one hand, it will increase the operation cost. On the other hand, since it cannot utilize the self-regulating ability of natural ventilation, more heat will be carried away by mechanical ventilation at low air temperatures, resulting in waste of the heat of the storage tank. Summary of the Utility Model

[0028] Embodiment 1
[0029] Please refer to Figures 1-3 Figures 1-3 , this embodiment provides a high-temperature storage tank foundation capable of ventilation and heat dissipation. The high-temperature storage tank foundation 1 is a prior art, which sequentially includes a thermal insulation layer, a ventilation layer, and a bearing foundation from top to bottom. The ventilation layer is provided with an independent mechanical ventilation device and a natural ventilation device. The natural ventilation device includes a plurality of natural ventilation pipes 2, and the mechanical ventilation device includes a plurality of mechanical ventilation pipes 31 and a main pipe 32 connecting all the mechanical ventilation pipes 31. The main pipe 32 is connected to a fan 4. During use, the mechanical ventilation device and the natural ventilation device are independent of each other.
[0030] Specifically, the distribution of the mechanical ventilation pipes 31 and the natural ventilation pipes 2 can be arranged arbitrarily according to actual needs, or the mechanical ventilation pipes 31 and the natural ventilation pipes 2 can be arranged in two upper and lower layers, that is, all the mechanical ventilation pipes 31 are horizontally arranged as a mechanical ventilation layer, and all the natural ventilation pipes 2 are horizontally arranged as a natural ventilation layer. The mechanical ventilation layer and the natural ventilation layer are stacked vertically. It can also be that the mechanical ventilation pipes 31 and the natural ventilation pipes 2 are distributed in the same plane, and there are n natural ventilation pipes 2 between adjacent two mechanical ventilation pipes 31, n≥1. In this embodiment, the mechanical ventilation pipes 31 and the natural ventilation pipes 2 are distributed in the same plane, and there is 1 natural ventilation pipe 2 between adjacent two mechanical ventilation pipes 31.
[0031] In this embodiment, the two ends of the natural ventilation pipe 2 are respectively a natural air inlet 21 and a natural air outlet 22. The natural air outlet 22 is higher than the natural air inlet 21 to form natural convection by using the density difference of the inlet and outlet air. The natural air outlet 22 is provided with a rain-proof elbow 7 bent downward by 180°, and the rain-proof elbow 7 is also provided with a bird-proof net to prevent rain, sand and small animals from entering. To enhance the natural ventilation capacity, heat insulation is provided in the range where the pipeline outlet section leaks out of the ground, and heat insulation materials such as rock wool and glass wool with a thickness of 20 - 80 mm can be used.
[0032] In this embodiment, one end of the mechanical ventilation pipe 31 is the mechanical ventilation pipe A end, and the other end is the mechanical ventilation pipe B end. The mechanical ventilation pipe A end is higher than the mechanical ventilation pipe B end, and the main pipe 32 is connected to the mechanical ventilation pipe A end. Both the mechanical ventilation pipe A end and the mechanical ventilation pipe B end are provided with a rain-proof elbow 7 bent downward by 180°, and the rain-proof elbow 7 is also provided with a bird-proof net to prevent rain, sand and small animals from entering.
[0033] In this embodiment, several temperature detection devices 5, such as temperature sensors in the prior art, are also provided in the ventilation layer of the high-temperature storage tank foundation 1. They are installed at the height of the ventilation layer close to the bearing top surface of the foundation, arranged circumferentially at intervals of 2 to 8 meters, preferably between the ventilation pipes, to monitor the temperature of the bearing foundation in real time and feedback the signal to the main control system to form an early warning. The main control system is in the prior art, including but not limited to software and hardware such as computers and servers, and the fan 4 is connected to the main control system.
[0034] During actual use, the temperature detection device 5 detects the temperature of the high-temperature storage tank foundation 1 in real time. When the temperature of the foundation is lower than the high-temperature threshold, the main control system controls the fan 4 not to start. Air enters from the natural air inlet 21 of the natural ventilation pipe 2 and exits from the natural air outlet 22, flowing in from the bottom and out from the top. The density difference between the inlet and outlet air forms natural convection. Since the fan 4 is not started, the mechanical ventilation pipe 31 functions the same as the natural ventilation pipe 2 at this time and is used as the natural ventilation pipe 2 to jointly dissipate heat from the high-temperature storage tank foundation 1. When the temperature of the foundation is equal to or higher than the high-temperature threshold, the main control system controls the fan 4 to start, and the mechanical ventilation pipe 31 conducts mechanical ventilation to increase the heat dissipation air volume and improve the heat dissipation effect of the foundation to reduce the temperature of the foundation.
[0035] This application adopts a form that combines natural ventilation and mechanical ventilation to form a heat dissipation ventilation system with controllable temperature for high-temperature storage tanks. It can adapt to various meteorological conditions, accurately control the ventilation and heat dissipation effect, reduce the operating cost, and avoid waste of the heat of the storage tank. Moreover, the natural ventilation pipe 2 and the mechanical ventilation pipe 31 of this application are independent of each other and do not interfere with each other, avoiding reducing the air flow efficiency in the pipeline.
[0036] Embodiment 2
[0037] This embodiment is optimized on the basis of Embodiment 1. The difference between this embodiment and Embodiment 1 is that a valve 6 is also provided at the A end of the mechanical ventilation pipe, and the rest of the structure is basically the same as that of Embodiment 1. The on-off valve 6 can be a on-off valve or a regulating valve, and can be a manual valve or an electric valve.
[0038] Under normal circumstances, the valve 6 remains open. When the temperature of the foundation is lower than the high-temperature threshold, the fan 4 is not enabled, and the mechanical ventilation pipe 31 functions the same as the natural ventilation pipe 2 and is used as the natural ventilation pipe 2 for natural ventilation; when the temperature of the foundation is equal to or higher than the high-temperature threshold, the valve 6 is closed and the fan 4 is started for mechanical ventilation; when the temperature of the foundation is lower than the low-temperature threshold resulting in large heat loss, some or all of the pipeline valves 6 can be closed and the fan 4 is not enabled to reduce the ventilation volume, thereby reducing the heat loss.
[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
