I. Brief Description of Carbonated Beverage Sampling Equipment:

Water-vapor sampling devices are used for thermal systems in power plants and secondary loop systems in nuclear power plants for online chemical analysis, measurement, and network monitoring of water-vapor quality. Instrument racks are centrally arranged for various analytical instruments and allow for manual sampling. Over-temperature, over-pressure, and cutoff protection are provided for the water samples entering the instruments, and a cooling water cutoff protection system is also set up to ensure the safe and reliable operation of the instruments.

Carbonated Water Sampling Device and Boiler Water Sampling Equipment are used for sampling and cooling water in boiler rooms or power plants for laboratory analysis. Sampling coolers are utilized for heat exchange with high-temperature liquids and gases. The water in boilers and thermal systems is generally at high temperatures, which is not conducive for sampling and testing. Therefore, cooling should be applied during sampling, i.e., the sample from the sampling point is introduced into the sampling cooler for cooling. It is generally required that the sample can be cooled to below 30-40 degrees Celsius when the flow rate is maintained at 500-700 mL/min, in accordance with the standard DL/T 457-91 of the People's Republic of China's power industry.

IV. System Structure:

The high-temperature rack is equipped with functional components such as high-temperature and high-pressure valves, drain valves, pressure-reducing valves, pre-cooling units, coolers, protection systems, main inlets and outlets for cooling water, and temperature, pressure, and flow indicating meters. These components cool and reduce the pressure of high-temperature and high-pressure water samples and steam, lowering the supercritical water samples to the required temperature <40℃ and pressure <0.5mPa after reduction and cooling treatment.
