Description

Technical Field

[0001] This utility model relates to the field of liquefied petroleum gas technology, and in particular to a sludge treatment device for liquefied petroleum gas preparation. Background Technology

[0002] Liquefied petroleum gas (LPG) is a colorless, volatile liquid obtained by pressurizing and cooling natural gas or petroleum in an oil refinery. After LPG is produced in the refinery, it usually requires a sludge treatment device for cleaning. Currently available LPG sludge treatment devices generally have the problem of being inconvenient for users to treat sludge in containers of different sizes. Existing LPG sludge treatment devices usually use water pumps to extract the sludge, and then require manual intervention, which results in users spending a lot of time to complete the sludge treatment, thus reducing user work efficiency and failing to meet the needs of users' daily work. To address this, CN219149325U discloses "A Sludge Treatment Device for LPG Production". This solution, through the setting of an adjustment mechanism, facilitates the treatment of sludge containers of different sizes when users need to treat them, thereby improving the efficiency of treating sludge containers of different sizes, saving users the time spent on treating sludge containers of different sizes, and thus improving user work efficiency.

[0003] However, in this solution, after the scraper passes over the surface of the pool, a thin layer of oily substances or harmful chemical residues will remain. These residues are not only flammable and explosive, but also greatly increase the safety risks of subsequent maintenance operations. Therefore, a sludge treatment device for liquefied petroleum gas preparation is proposed. Utility Model Content
