On-line detector for safety condition of urea synthetic tower

At each tower section there is separately carrier gas which passes through pipe-line, leakage detecting hole to enter in the reinforcing layer composed of multi-layer veneer located in tower and out tube, and furrow between the tower body and inner tube, then passes through the other leakage detecting hole and pipe-line connecting to the gas analyzing instrument and signal processing system. Whenleakage occurs, the leakage medium along with the carrier gas enters the gas analyzing instrument to be analyzed, and the on line measurement is implemented by signal processing system. When the leakage medium control parameter reaches to the preset value, the warning will be given out instantly. Said invention is suitable to the other pressure container with inner tube and reinforcing layer withventilating hole.
