When detecting the boiler water sample, in order to ensure accuracy and safety, it is necessary to take a sample from the boiler system. Since the temperature of the boiler water is usually relatively high, when sampling, it is necessary to cool the water sample to the safe operation range, which requires the boiler water sampling cooling device.
[0003] Generally, the sampling cooler is installed in the bottom space of the boiler. The steam-water is led from the continuous blowdown pipe at the bottom of the steam drum to the inlet of the cooler, and the circulating water pipeline is led from the plant to the inside of the cooler for cooling to achieve the sampling purpose. This not only has a long pipeline and is not conducive to maintenance, but also needs to be equipped with a heat preservation room and heating method in winter to prevent the sampling device from being frozen.
