Description

Jet steam extractor with strong adaptability

Technical Field

Background

In the operation process of the industrial steam supply system, due to the fact that certain deviation exists between the actual working condition and the system design working condition, partial valves of the industrial steam supply system cannot meet the actual production requirements, partial regulating valves cannot be opened due to large differential pressure, the operation linearity is poor, the regulating precision is insufficient, and the like. Hidden troubles and uncertainty are brought to stable operation of a unit and continuous and reliable steam supply of an industrial steam supply system. The system can not be shut down, and the valve can not be isolated, which causes troubles to the operation and maintenance personnel.

However, after the industrial steam supply system is stopped, the electric stop door connected with the industrial steam supply system and the unit leaks inwards, and the industrial steam supply system cannot be tightly closed. After many times of tightening, high-temperature steam still leaks into the pipeline, and the temperature of the pipeline and the required maintenance valve is always kept above 90 ℃. The safety of maintainers cannot be guaranteed, and the operation condition is not met. The industrial steam supply system is only shut down for a few days, and if the industrial steam supply system is not overhauled, the stable operation of the system cannot be guaranteed.

Therefore, there is a need to provide a new adaptable jet steam extractor to solve the above technical problems.
