この発明は、気液混合物の輸送方法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] This invention relates to a method for transporting a gas-liquid mixture.

ラインによって輸送する場合、スラリー状石炭に空気を
混入させ、気液混合物として輸送すれば、スラリー状石
炭のみを輸送する場合に比べて少ない圧力損失でスラリ
ー状石炭を輸送できることが知られている。When transporting very viscous coal, for example in the form of a slurry, by pipeline, if air is mixed into the slurry coal and transported as a gas-liquid mixture, the pressure will be lower than when transporting only the slurry coal. It is known that slurry coal can be transported at a loss.

減効果が得られず、全体的には、気体混合によるメリッ
トはほとんど無くなってしまう。The effect of reducing pressure loss due to gas mixing strongly depends on the gas-liquid volume flow ratio within the pipeline, and the gas-liquid volume flow ratio that provides a large pressure loss reduction effect is limited to a narrow range. Even if the optimal gas-liquid volumetric flow rate ratio is set at the pipeline inlet, the volumetric flow rate of the system body increases due to pressure drop on the downstream side of the pipeline, resulting in insufficient pressure drop reduction effect. , overall, the benefits of gas mixing are almost eliminated.

A liquid level gauge 5 is attached to the gas reservoir 4 to measure the level of liquid stored therein. A liquid level signal from the liquid level gauge 5 is input to a controller to be described later. A flow rate adjusting pulp 6 and a gas flow meter 7 are attached to the gas reservoir 4. The gas flow rate signal from the gas flow meter 7 is inputted to the controller. The opening degree of the pulp 6 is controlled.

溜り４内から外部に流出する虞れはない。As mentioned above. According to the method of the present invention, a predetermined amount of gas is discharged to the outside from the gas-liquid mixture flowing in the pipeline 1, and the gas-liquid volumetric flow rate in the pipeline 1 is always maintained at an appropriate value. Therefore, the gas-liquid mixture is transferred to pipeline 1
transported within the interior with little pressure loss. If the liquid level in the gas reservoir 4 rises above the upper limit, the controller 8
Since a closing signal is issued to the pulp 6 from the gas reservoir 4, there is no risk of the liquid flowing out from the gas reservoir 4 to the outside.
