Description

Technical Field

[0001] This utility model relates to the field of methyl tert-butyl ether preparation technology, and in particular to a storage device for methyl tert-butyl ether preparation. Background Technology

[0002] Methyl tert-butyl ether (MTBE), an important organic compound, is widely used in the chemical industry. With its high octane rating and good anti-knock properties, it is often used as a gasoline additive to effectively improve gasoline quality, reduce engine knocking, thereby improving vehicle performance and reducing harmful emissions from exhaust gases, which is beneficial for environmental protection and energy utilization. However, MTBE has certain water solubility and potential environmental pollution risks. If leaked into water bodies, it will spread rapidly and is difficult to degrade naturally, causing long-term harm to groundwater resources. Therefore, its production, transportation, and use require strict control.

[0003] Storage devices for methyl tert-butyl ether (MTBE) are crucial for its safe storage. These devices must have excellent sealing properties to prevent MTBE from evaporating and leaking into the environment. They must also be corrosion-resistant, as MTBE can corrode some metal materials. In addition, the storage devices should be equipped with a comprehensive safety monitoring and emergency response system that can monitor storage environment parameters in real time and promptly issue alarms and take measures in case of abnormalities to ensure the safe storage of MTBE and the safety of the surrounding environment.

[0004] Patent document CN220683475U discloses a storage device for the production of methyl tert-butyl ether, including a chassis. An annular groove is formed on the bottom edge of the chassis. Protrusions are uniformly fixed to the bottom of the inner cavity of the annular groove. A left side plate is detachably installed on the left side of the inner cavity of the annular groove. Grooves are formed on both the front and rear sides of the right side of the left side plate. This storage device for the production of methyl tert-butyl ether utilizes a top cover structure and a locking block structure. In use, the left and right side plates are inserted into the annular groove, automatically aligning with the through holes and protrusions. The annular groove and protrusions automatically reinforce the installed left and right side plates and the chassis. Then, the movable rod is stretched and rotated to bring the locking blocks one and two to the same horizontal plane. The locking blocks one and two are then combined, and the top cover is installed on top of the left and right side plates. Multiple combinations achieve rapid assembly, effectively fixing the heat insulation plate and improving the device's heat preservation effect.

[0005] As in the prior art of the aforementioned patent, the aforementioned device is used to store methyl tert-butyl ether. Methyl tert-butyl ether is generally prepared in a reaction vessel. After preparation, the methyl tert-butyl ether needs to be transferred to the storage device. However, the aforementioned device does not have the conditions for transfer. An external pump is required to connect to the outlet of the preparation device in order to successfully transfer the finished solution. However, in this process, the sealing of the pipeline connection and the stability of the device will affect the solution transfer. Furthermore, the aforementioned device is only protected by a partition, which has poor heat insulation and fireproof performance. Utility Model Content
