Description

Technical Field

[0001] This utility model relates to an enamel-lined reactor that facilitates sampling, belonging to the field of chemical reactor technology. Background Technology

[0002] Enameled reactors are corrosion-resistant equipment widely used in chemical, pharmaceutical, and food industries, where high-temperature, high-pressure, or highly corrosive chemical reactions often occur. Real-time sampling and monitoring of reaction progress and material composition are crucial for ensuring product quality during production. Traditional sampling methods for enamel-lined reactors use negative pressure suction, but this method can only extract liquid samples from a fixed height within the reactor, making multi-layer sampling impossible and hindering a comprehensive assessment of the reaction state. Furthermore, the sampling bottles are typically threaded onto the sampling port, making disassembly and replacement cumbersome. Utility Model Content
