Title:
GAS-LIQUID SEPARATION DEVICE FOR ASPIRATION GAS ANALYSIS DEVICE
Document Type and Number:
Japanese Patent JP3154078
Kind Code:
B2
Abstract:
PURPOSE: To sufficiently remove moisture from aspiration gas by causing the gas to flow into a gas-liquid separation chamber to collide with a groove formed vertically on an inner wall for condensation.
CONSTITUTION: A testee's aspiration gas flows into a gas-liquid separation chamber 11 via an aspiration gas inflow passage, due to the suction force of a gas discharge passage 17 connected to a suction pump, and collides with a plurality of V-grooves 6 formed at a position opposed to the separation chamber 11. As the grooves 16 have a large area and good compatibility with water, moisture in the gas is condensed on the surface of the grooves 16. Then, the condensed gas drops along the grooves 16 due to the own weight thereof, and stagnates in a water receiving section via a water drop hole 13 and a discharge section 14. On the other hand, the gas with moisture removed in the chamber 11 is drawn through the exhaust passage 17 and introduced to the sensor section of an aspiration gas analysis device.
