APPARATUS FOR CONTINUOUSLY MEASURING WET BULB TEMPERATURE

摘要

PURPOSE: An apparatus for continuously measuring wet bulb temperature is provided to understand and control the operation state by applying the apparatus to a semi-dry process. CONSTITUTION: A thermo couple(2) for measuring the dry bulb temperature is installed in a gas flow channel(1) to be measured, and connected to a gas temperature controller(10) for maintaining the temperature of a thermostatic bath(5) to be equal to the temperature of gas to be measured, and a recording device(14). A gas inlet pipe(3) is introduced into the thermostatic bath through a blower(4). A first container(7) for supplying a water for wetting a wick(6) is located within the thermostatic bath, and connected to a second container(12) for storing a preliminary material. A pipe(11) extended from the bottom of the second container is connected to the first container through a water feed pipe(8). The second container includes a controller(13) so as to control the first and second containers to have the same water surface level. The thermo couple for measuring the dry bulb temperature, thermo couple for the wick for measuring the wet bulb temperature, and a thermo couple(9) for the gas temperature controller disposed within the thermostatic bath are connected to the recording device.
