摘要： In an abnormality monitoring apparatus of the present invention, a plurality of detectors (13, 14) are arranged at a plurality of positions in the axial direction of a pipeline (11) to detect respective sound waves (37) propagating from a position (B) of occurrence of abnormality. The aforementioned position is calculated from a sound wave detection time difference between the detectors (13, 14) and position between the detectors (13, 14). The apparatus further includes an abnormal waveform memory unit (28) for storing the waveforms of a plurality of kinds of typical abnormal sound waves generated from abnormality on the pipeline (11). A display device (19) displays, on the same image screen, the abnormal waveform stored in the abnormal waveform memory unit and that of the sound wave detected. It is, therefore, possible for a monitoring personnel to readily identify a kind of abnormality occurred.

摘要： Sensors (13,14) detecting each sound wave propagated from an abnormality occurring position with a fluid as a medium are disposed in a number of positions in the axial direction of the piping. The abnormality occurring position is calculated form the differences of sound wave detection timings between sensors and from the distances between the sensors. An abnormal waveform memory portion for storing sound waveforms resulting from a number of kinds of typical abnormalities is disposed and the abnormal sound waveforms stored in this abnormal waveform memory portion and a detected sound waveform are displayed on the same screen of a display device. Accordingly, the operator can easily identify a kind of abnormality. @(38pp Dwg.No.2/9)@.

摘要： PURPOSE:To detect the position of abnormality occurrence in piping simply, quickly and exactly by severally providing acoustic wave detectors at the plural spots of piping, and computing the position of occurrence on the time difference of detection. CONSTITUTION:Piping is buried underground, and a pair of detectors 13, 14 for detecting acoustic wave are provided in the piping 11. The detectors 13, 14 are composed of a pair of acoustic sensors 13a, 13b, and 14a, 14b, and axially arranged at intervals of (l3). When a shock is given on the outer surface of the piping 11, the acoustic wave occurs in the piping 11 through fluid acting as an medium. For instance, in the case where the fluid flows toward a direction A, since the acoustic wave at the time of propagating toward the detector 14 is stronger than the acoustic wave at the time of propagating toward the detector 13, a data processing device 18 computes the difference of the acoustic wave detecting timing in each of the detectors 13, 14 to determine the position of an abnormality occurrence. Thus the reliability of the whole of a device can be improved.

摘要： PURPOSE:To prevent adhered materials from sticking to the interior of heating furnace tubes by boosting the pressure of a mixture of coal with a solvent, heating the mixture, feeding the boosted and heated mixture to a coal liquefier and separately feeding a mixture of a coal liquefaction catalyst and solvent to the above-mentioned liquefier. CONSTITUTION:Coal and a solvent, such as anthracene oil, are fed to a pulverizer 1, mixed, regulated, then placed in a preparation vessel 2 and prepared into a slurry, which, together with hydrogen, is fed into a tube (4a) of a heating furnace 4 with a pressure boosting pump 3, subjected to pressure boosting and heating and subsequently fed to a liquefaction reactor 5. On the other hand, separately from the coal and solvent, a coal liquefaction catalyst and a solvent are placed in another preparation vessel 11, mixed and prepared and the mixture prepared into a slurry is then directly fed to the liquefaction reactor 5 with a feed pump 12 without passing through the heating furnace. Furthermore, a mixture of fine iron oxide powder with sulfur powder or fine iron sulfide powder is used as the above-mentioned catalyst.

摘要： PURPOSE:To stably operate a slurry treatment system while preventing solid materials from accumulating, by guiding a high-temp. and high-pressure slurry produced in a coal liquefying facility etc. into a slurry reactor of suspension bubble column type, where the slurry is reacted with a counterflowing hydrogen gas and discharging any product from the bottom thereof in a controlled amt. CONSTITUTION:A high-temp. and high-pressure slurry of coal etc. heated to 350-400 deg.C in a heating furnace in a coal liquefying facility etc. is fed through an upper feed line 12 into a slurry reactor 2b of suspension bubble column type. A hydrogen gas pressurized by the use of an H2 gas compressor is fed through a lower feed line 11 into the reactor. In the reactor 2b, the slurry is uniformly reacted with the hydrogen gas in a counterflow state. The coal slurry obtd. as a reaction product is transferred through a bottom discharge line 13 to a next step while controlling the opening of the valve 15 by means of a level controller 16, a flow rate control valve 15, and a control line 17 so as to attain a desirable liq. level height. On the other hand, the hydrogen gas entrained with mist vapor is discharged from an upper discharge line 14. The mist is separated, and the hydrogen gas is recycled for use.
