Online pre-processing system

The electrical vaporization device uses a special heating type pressure reducing valve in the front-end pressure reducing unit to ensure the instantaneous vaporization of liquid samples or prevent condensation during the pressure reduction process after the sample gas is taken out.

Multi channel sample switching device, the switching of multi-channel sampling is controlled by PLC, which can achieve multiple working modes such as automatic inspection of multiple channels (the detection interval time of each channel depends on the specific analysis time), selective detection, and manual control.

Pre treatment of negative pressure samples, collection of negative pressure samples, suction at the outlet of the analytical instrument, and measurement of the samples through the analytical instrument. Suitable for sample analysis of toxic and harmful gases or industrial recycling requirements.

The sample discharge recovery device and the analysis system's sample discharge return sampling or recovery pipeline effectively solve problems such as environmental emissions, laboratory waste liquid treatment, and manual sampling waste.

Water removal and air cooling device, the analysis system has a water containing process. This device adds an air cooling and water removal system to effectively solve the water content in the process pipeline, and dual redundant filters are added to the outlet.

High pressure pretreatment device, equipped with dual redundant filter system, front needle valve flow restriction, and inlet filter system, effectively solves the problem of high pressure in the front stage.

Water cooling device uses industrial cold water to solve the temperature of the sample gas at the outlet of the on-site process pipeline, ensuring the constant temperature of the sample gas in the rear system.

The steam vaporization device ensures the instantaneous vaporization of liquid samples or prevents condensation during the pressure reduction process after the sample gas is taken out, effectively solving the temperature level of high temperature explosion prevention for pressure reducing valves.
