Description

Technical Field

[0001] The utility model relates to the technical field of sampling port blocking, in particular to a sampling port blocking device for an MVR crystallization system. Background Art

[0002] MVR stands for Mechanical Vapor Recompression. MVR utilizes a steam compressor to compress secondary steam, converting electrical energy into heat, increasing the enthalpy of the secondary steam. This heated steam then enters the evaporator, where it is heated to maintain the liquid at a boiling point. The heated steam itself condenses into water. This fully utilizes steam that would otherwise be discarded, recovering latent heat and improving thermal efficiency.

[0003] However, the existing MVR crystallization system still has certain shortcomings during use. The sampling port may be blocked during use, and the sampling port cannot be kept unobstructed, thereby reducing the practicality and continuity of the MVR crystallization system during use. The blockage of the sampling port will also affect the normal use of the MVR crystallization system. Therefore, we propose a sampling port blocking device for the MVR crystallization system.
