1. a kind of device of on-line checking coal dust drying process volatile matter, the dress of the on-line checking coal dust drying process volatile matterIt puts including gas handling system, feeding system, fluidized-bed reactor, piece-rate system and detecting system;

  • It is characterized in that,The gas handling system includes the first nitrogen gas cylinder (1), dioxide bottle (2), oxygen gas cylinder (3), water pot (4), meteringPump (5), the first preheater (6), the second preheater (7) and mixer (8);

    The first nitrogen gas cylinder (1), the carbon dioxideGas cylinder (2) and the oxygen gas cylinder (3) pass sequentially through pressure reducing valve A, regulating valve B, flowmeter C and check-valves D and described the respectivelyTwo preheaters (7) are connected;

    Second preheater (7) is connected with the mixer (8);

    The water pot (4), the meteringPump (5) and first preheater (6) are sequentially connected;

    First preheater (6) passes sequentially through regulating valve B, flowmeter C and stopsValve D is returned with the mixer (8) to be connected;

    The feeding system includes sequentially connected second nitrogen gas cylinder (9), hopper (10) and screw conveyor (11);

    Wherein instituteIt states the second nitrogen gas cylinder (9) and passes sequentially through pressure reducing valve A, regulating valve B, flowmeter C and check-valves D and be connected with the hopper (10)It connects;

    The fluidized-bed reactor includes reacting furnace (12), heating furnace (13), air distribution plate (14);

    The reacting furnace (12) respectively withThe heating furnace (13) is connected with the air distribution plate (14);

    The piece-rate system includes sequentially connected cyclone separator (15), cooler (16), accumulator tank (17) and secondary filterDevice (18);

    The detecting system includes gas chromatograph (19) and portable gas detector (20);

    The reacting furnace (12) is connected with the screw conveyor (11);

    The air distribution plate (14) and the mixer (8) phaseEven, the effusion gas port of the reacting furnace (12) successively with the cyclone separator (15), the cooler (16), the accumulator tank(17), the accurate filter (18), the gas chromatograph (19) and the portable gas detector (20) are connected;

    The reacting furnace (12) and the cyclone separator 15 are both provided with discharge K and discharge L, the accumulator tank(17), the accurate filter (18) is both provided with leakage fluid dram M and leakage fluid dram N, the accurate filter (18) respectively with gasChromatography (19), portable gas detector (20) are connected, and form gas chromatograph (19) and portable gas detector(20) parallel-connection structure.
