Description

Technical Field

[0001] This utility model relates to the technical field of molten salt storage equipment, specifically to a multi-point temperature measurement device for molten salt storage tanks. Background Technology

[0002] In fields such as solar thermal power generation and industrial heating, molten salt storage tanks are key equipment for storing high-temperature molten salt. The temperature of the molten salt inside the tank is an important parameter for ensuring the safe and stable operation of the system. Molten salt has a high operating temperature, and temperature stratification may occur inside the storage tank due to factors such as natural convection and uneven heat transfer.

[0003] Existing methods for measuring the temperature of molten salt storage tanks mostly involve fixed-point temperature measurement, meaning that temperature measuring points are fixed at one or more locations within the tank. This method can only obtain temperature information at fixed locations within the tank and cannot comprehensively reflect the overall temperature distribution of the molten salt. In particular, the surface temperature of high-temperature molten salt is difficult to measure, and therefore cannot accurately represent the true temperature of the molten salt inside the tank, which can easily lead to deviations in the system's judgment of the molten salt temperature.

[0004] Therefore, there is an urgent need for a device that can monitor the temperature at multiple points inside molten salt storage tanks in order to obtain molten salt temperature information comprehensively and accurately, and ensure the safe and stable operation of the system. Utility Model Content

[0006] Therefore, one objective of this utility model is to propose a multi-point temperature measuring device for molten salt storage tanks. This device utilizes a floating collar to float on the surface of molten salt and monitors the surface temperature of the molten salt in real time through a first temperature sensor, ensuring comprehensive temperature detection and providing reliable data support for temperature control systems and safety monitoring.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-point temperature measuring device for a molten salt storage tank, comprising a storage tank, wherein multiple fixed rods are symmetrically installed on the inner wall of the bottom of the storage tank, a floating collar is slidably installed on the outer wall of the fixed rods, a first temperature sensor is embedded in the outer wall of the floating collar, a heat-conducting pipe is fixedly connected to the inner wall of the bottom of the storage tank, and multiple second temperature sensors are sequentially embedded in the outer wall of the heat-conducting pipe from top to bottom, and the floating collar is selected as an alumina hollow ring.

[0008] Preferably, a delivery pump is installed on the top of the storage tank, and the outlet of the delivery pump is connected to a delivery pipe, one end of which passes through the top of the storage tank.

[0009] Preferably, the end of the delivery pipe away from the delivery pump is connected to a ring liquid pipe, and the outer wall of the ring liquid pipe is provided with a plurality of liquid outlets.

[0010] Preferably, the top of the storage tank is fitted with a cover, and the delivery pump is located inside the cover.

[0011] Preferably, the top of the storage tank is fitted with a barrier.

[0012] Preferably, the heat pipe is made of a nickel-based alloy.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, multiple fixed rods are symmetrically installed on the inner wall of the bottom of the storage tank, and a floating collar is slidably installed on the outer wall of each fixed rod. A first temperature sensor is embedded in the floating collar. The floating collar is made of hollow alumina ring material to avoid reaction with high-temperature molten salt and can float on the surface of molten salt, which facilitates real-time monitoring of the surface temperature of molten salt. It is also equipped with a second temperature sensor at multiple points to monitor the temperature changes at different heights inside the storage tank, ensuring comprehensive temperature detection and providing reliable data support for the temperature control system and safety monitoring.

[0021] In this utility model, such as Figures 1-4 As shown, multiple fixed rods 7 are symmetrically installed on the bottom inner wall of the storage tank 1. A floating collar 10 is slidably installed on the outer wall of the fixed rods 7. A first temperature sensor 11 is embedded in the outer wall of the floating collar 10. A heat-conducting pipe 6 is fixedly connected to the bottom inner wall of the storage tank 1. Multiple second temperature sensors 12 are embedded in the outer wall of the heat-conducting pipe 6 from top to bottom. The floating collar 10 is selected as an alumina hollow ring.

[0022] In use, multiple fixing rods 7 are symmetrically installed on the inner wall of the bottom of the storage tank 1. A floating collar 10 is slidably installed on the outer wall of each fixing rod 7. A first temperature sensor 11 is embedded in the floating collar 10. The floating collar 10 is made of alumina hollow ring material, which can avoid adverse reactions with high-temperature molten salt and enable the floating collar 10 to float on the surface of high-temperature molten salt. This allows the first temperature sensor 11 to monitor the temperature of the surface of high-temperature molten salt in real time. It can also be used in conjunction with the first temperature sensor 11 to monitor the temperature changes of different height points of molten salt in the storage tank 1 in real time.

[0023] Furthermore, the heat pipe 6 is made of a nickel-based alloy. As the material of the heat pipe 6, the nickel-based alloy has high high temperature resistance and good thermal conductivity, and can effectively withstand the working load in high temperature environment.

[0024] like Figure 1 and Figure 2 As shown, a transfer pump 2 is installed on the top of the storage tank 1. The outlet of the transfer pump 2 is connected to a transfer pipe 5. One end of the transfer pipe 5 passes through the top of the storage tank 1. The transfer pump 2 can transfer high-temperature liquid molten salt into the storage tank 1 through the outlet and the transfer pipe 5 to meet the liquid molten salt transfer requirements. In addition, a cover 4 is installed on the top of the storage tank 1. The transfer pump 2 is located inside the cover 4. The cover 4 completely covers the transfer pump 2 to protect it from pollution and damage from the external environment.

[0025] Furthermore, the end of the conveying pipe 5 away from the conveying pump 2 is connected to a ring liquid pipe 8. The outer wall of the ring liquid pipe 8 is provided with several liquid outlets 9. The ring liquid pipe 8 guides the liquid molten salt from the conveying pipe 5 to the multiple liquid outlets 9. The liquid outlets 9 can uniformly input the liquid molten salt into the storage tank 1 container, improving the uniformity and efficiency of liquid conveying. The conveying pump 2 is a molten salt circulation pump, and the conveying pipe 5 is a high-temperature resistant metal pipe.

[0026] Reference Figure 1 and Figure 2 The top of the storage tank 1 is equipped with a barrier 3, which surrounds the top of the storage tank 1 to provide protection and prevent operators from accidentally falling from the top of the storage tank 1.

[0027] Based on the above technical solution, the working steps of this solution are summarized as follows: In this utility model, the storage tank 1 can store high-temperature liquid molten salt. Multiple fixing rods 7 are symmetrically installed on the inner wall of the bottom of the storage tank 1. A floating collar 10 is slidably installed on the outer wall of each fixing rod 7. The floating collar 10 is equipped with a first temperature sensor 11. The floating collar 10 is made of alumina hollow ring material, which can avoid adverse reactions with high-temperature molten salt and allow the floating collar 10 to float on the surface of high-temperature molten salt. This facilitates the first temperature sensor 11 to monitor the temperature of the surface of high-temperature molten salt in real time. In conjunction with the first temperature sensor 11, the temperature changes of molten salt at different heights in the storage tank 1 are monitored in real time, thereby ensuring the comprehensiveness of temperature detection in the molten salt storage tank and providing reliable data support for the tank temperature control system and temperature safety monitoring.
