PURPOSE:To simply and accurately measure the concentration of dust in the fluid of gas-liquid mixed phase, by providing a hollow part for collecting coarse fluid particles which is proved the inlet and outlet at the position not facing to each other and a filter paper for collecting only dust after evaporating the liquid component. CONSTITUTION:The nozzle 10 is inserted into the flue of the dust concentration measuring apparatus 2 towards flowing direction of gas, and the flowing direction of gas and nozzle 10 are faced to each other at the time of intaking the fluid to be measured. Japan Industrial Standard method JISZ8808 is used for the present measurement. A vacuum pump etc. are connected to the gas outlet 21 and the fluid to be measured is allowed to flow in the apparatus 2 from the nozzle 10. Coarse liquid drops are collected in the hollow part i.e. the inertia corrision part 11 and residual liquid drops are evaporated in the evaporation part 12, 18 and then, only the dust is collected by the filter paper 1 for dust collection. |
