Method and system for gas transfer type fine powder quantitative feeding

A gas transfer fine powder quantitative feeding system comprising:

• a humidifying chamber for humidifying a carrier gas;
• and
• a gas transfer fine powder quantitative feeder that quantitatively feeds a mixed fluid of the carrier gas and fine powder to a fine powder using device by feed of the carrier gas from the humidifying chamber,
• wherein the gas transfer fine powder quantitative feeder comprises:
• a fine powder storage container that stores the fine powder;
• a housing that stores the fine powder storage container in a gas-tight manner;
• a feed port that feeds the carrier gas to the housing;
• a flow rate adjustment mechanism that adjusts a feed amount of the carrier gas to the housing;
• a feed nozzle that feeds the fine powder from the fine powder storage container to the fine powder using device entrained with the carrier gas;
• a position detection sensor for detecting a relative position between the feed nozzle and the fine powder surface;
• a driving part that moves the feed nozzle in an up and down direction;
• and
• a humidity measuring sensor for measuring humidity in the housing;
• and
• wherein the humidifying chamber comprises:
• a water tank that stores liquid for humidifying the carrier gas;
• an ultrasonic vibration mechanism for atomizing the liquid;
• and
• a humidity control mechanism for controlling humidity in the housing in conjunction with the humidity measuring sensor.
