Description
Technical Field
The utility model relates to the technical field of chemical equipment, in particular to a molten salt tank for a molten salt pyrolysis system.
Background
In a fused salt pyrolysis system, fused salt heat exchange mainly comprises three devices: pyrolysis furnace, molten salt groove. In order to ensure the stability of the system, the fused salt heat exchange in the general pyrolysis system adopts a double-circulation mode, namely a large circulation mode and a small circulation mode. The large circulation means that high-temperature molten salt in the molten salt tank is pumped into the pyrolysis furnace through a circulating pump, and flows back into the molten salt tank after heat exchange occurs in the pyrolysis furnace. And the small circulation is that molten salt in the molten salt tank is pumped into the molten salt furnace by a circulating pump to be further heated and heated, and then flows back into the molten salt tank. Considering factors such as equipment investment cost, occupied area, safety and the like, the molten salt tank is generally only provided with one molten salt tank, and the buffer effect is achieved on the whole molten salt system. At present, after a general fused salt tank structure can lead to fused salt backflow, low-temperature fused salt and high-temperature fused salt are mixed, and temperature distribution in the fused salt tank is uneven, so that the temperature of a pyrolysis system is uncontrolled, and the stability of pyrolysis reaction is affected. In summary, the current general molten salt tank structure is more suitable for a single-cycle molten salt heat exchange system, namely, the low-temperature molten salt after heat exchange by pyrolysis is not returned to the molten salt tank but directly enters the molten salt furnace for heating and temperature rise, and the process flow is simpler but has poorer stability.
For example, patent CN213355616U discloses a molten salt storage tank and a molten salt system, which provides a structure of the molten salt storage tank, a feed inlet is arranged on a tank body, and a liquid collecting groove protruding downwards from the bottom surface of the tank body is arranged on the bottom surface of the tank body; the heating component is arranged at the outer side of the tank body; the pumping assembly solves the limitations of conventional tanks existing in the prior art due to their own construction. The patent is used for solving the problem that more molten salt remains in the molten salt storage tank, and the purpose is different from the utility model, and the utility model is applied to a pyrolysis system, and more stability of the system is considered, a certain amount of molten salt is required to be buffered in the storage tank, and meanwhile, the stability of the temperature of the molten salt is ensured.
For example, patent CN203459055U discloses a molten salt tank, which adopts a mode of directly heating molten salt in real time by an electric heating rod, so that the molten salt can be directly heated to a working temperature, an electric heating furnace device of a traditional molten salt heating device is omitted, and the manufacturing cost is reduced. The patent has a better effect on a system with smaller molten salt amount, and for a double-circulation pyrolysis system with larger molten salt demand amount, due to the fact that the electric heating mode of the heating rod is slower in speed, the purpose of real-time heating cannot be achieved, and therefore the system is crashed due to the fact that the temperature of the molten salt is too low.
For example, patent CN216049306U discloses a steam molten salt tank, which provides a mode and molten salt tank structure for evaporating salt, a steam coil is arranged in the molten salt tank, a heating coil is arranged outside the steam coil, and a steam inlet and a condensate outlet of the steam coil are arranged outside the molten salt tank. The steam temperature of the structured fused salt of the fused salt tank is generally only about 30 degrees higher than the melting point of the fused salt, so that the quality of the fused salt is ensured. However, for pyrolysis systems, there is generally no steam in the factory floor, and therefore, the utility is low. And the molten salt tank structure is obviously different from the molten salt tank structure.
In summary, the optimization of the molten salt tank structure at present is that steam heating is adopted to replace traditional electric heating on the salt melting mode in the starting stage; the electric heating rod is directly used for replacing the molten salt heating furnace, and in addition, the design for ensuring that no redundant molten salt exists in the molten salt tank is provided. In a fused salt pyrolysis system, steam is not generated generally, and the cost is high by adopting a steam heating mode, so that the system is more complex; on the other hand, in order to maintain the stability of the system, the molten salt tank needs to have a certain molten salt allowance for buffering, and meanwhile, the temperature in the molten salt tank is ensured to be relatively uniform, and the temperature of the molten salt at the outlet of the molten salt large circulation pump is stable and reliable. Therefore, the optimization and improvement of the fused salt tank cannot well meet the stable operation requirement of the pyrolysis system.
