Description

Technical Field

[0001] This utility model relates to the field of sampling technology for coal-based mixed C4 storage tanks, specifically a sampling device for coal-based mixed C4 storage tanks. Background Technology

[0002] Coal-based mixed C4 storage tanks are used to store mixed C4 hydrocarbons produced during coal-to-oil or coal chemical processes. The main components include butane, isobutane, butene, and isobutene. These hydrocarbons have wide applications in the chemical and energy fields. Coal-based mixed C4 storage tanks are crucial in coal chemical processes. Reasonable design, strict safety measures, and effective maintenance and management are the keys to ensuring their safe operation.

[0003] Chinese patent CN217819564U discloses a sampling device for a coal-based mixed C4 storage tank. This patent discloses a technical solution to reduce the replacement time and solves the problem that existing sampling devices generally have the following issues: the inlet and outlet pipes of the storage tank are 500mm higher than the manhole at the bottom of the storage tank, and the manhole at the bottom of the storage tank is 1000mm higher than the sampler inlet. This can easily cause a dead zone at the bottom of the storage tank, resulting in the enrichment of heavy components in the C4 product and the sample being unrepresentative. At the same time, it also reduces the impact of the enriched trace moisture on the quality of the C4 product.

[0004] When in use, the device reduces the replacement time by connecting the main inlet and outlet pipelines to the sampler inlet pipeline through the third delivery pipe and the fourth valve. However, during sampling, the liquid flows naturally and enters the interior of the sampling tank, resulting in low sampling efficiency and reduced effectiveness. Therefore, a sampling device for a coal-based mixed C4 storage tank is proposed to solve the above problems. Utility Model Content
