Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明はスラリーの輸送方法に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for transporting slurry.
従来、非常に高い粘度のスラリーをパイプライン輸送す
る時、気体を注入して輸送すれば、スラリー単相流の場
合よりも圧力損失が少く輸送することが知られている。Conventionally, when transporting a slurry with a very high viscosity through a pipeline, it has been known that if gas is injected for transport, the pressure loss is smaller than in the case of a single-phase slurry flow.
このように気体注入することによって圧力損失を低減す
る効果はパイプライン内の流動様式と気体のみかけ流速
によって影響され、この流)様式とみかげ流速が一定の
範囲内にある場合にのみ大きな圧力損失低減効果がある
。The effect of reducing pressure loss by injecting gas in this way is affected by the flow pattern in the pipeline and the apparent flow velocity of the gas, and a large pressure loss will occur only when the flow pattern and apparent flow velocity are within a certain range. It has a reducing effect.
即ちスラリーのパイプライン輸送においてパイプライン
入口で流動状態とみかけ流速の流送条件を適切に設定し
てスラリーを送り込んでもパイプライン下流では圧力の
降下により気体の体積流量が増加するため流動状態が適
切な流送条件の範囲から逸脱して、圧力損失の低減効果
が得られないことがあり、又全体的には気体注入による
圧力損失の低減効果は小さいか、あるいは全く無くなる
こともある。このため従来広のような方法がとられてい
た。In other words, when transporting slurry through a pipeline, even if the flow conditions of the flow state and apparent flow velocity are set appropriately at the pipeline inlet and the slurry is sent, the flow state is not appropriate because the volume flow rate of gas increases due to the pressure drop downstream of the pipeline. If the flow conditions deviate from the range, the effect of reducing pressure loss may not be obtained, and the overall effect of reducing pressure loss due to gas injection may be small or may be completely absent. For this reason, a conventional method has been used.
(1)圧力損失が輸送に影響する限界までの短いパイプ
ラインにのみ行う。(1) Only apply to short pipelines where pressure loss affects transportation.
(2)配管の途中から一定量の気体を排出して、スラリ
ーの流動状態を一定の範囲内に保ちながら輸送する。(2) A certain amount of gas is discharged from the middle of the piping, and the slurry is transported while maintaining the flow state within a certain range.
前記の従来の方法には次のような問題があった。 The conventional method described above has the following problems.
(1)圧力損失限界、までの短いパイプライン輸送は輸
送距離に限定が生じるため実用に適さない、(2)一定
量の気体を配管途中から排出するための装置及び機構が
複雑高価となり輸送コストが犬となる。(1) Short pipeline transportation up to the pressure drop limit is not suitable for practical use because the transportation distance is limited; (2) The equipment and mechanisms for discharging a certain amount of gas from the middle of the pipe are complex and expensive, resulting in transportation costs. becomes a dog.
本発明はこのような問題点を解決するためなされたもの

By keeping the flow state of the gas-liquid two-phase mixture within an appropriate range, it is possible to transport the gas-liquid two-phase mixture with less pressure loss than in the case of a single-phase slurry.
第1図は本発明の構成を示す模式図である。図において

装置1からの供給ライン5が連結している。FIG. 1 is a schematic diagram showing the configuration of the present invention. In the figure, 1 is a gas supply device that can continuously supply gas at a constant flow rate, 2 is a slurry supply device that can continuously supply a constant flow rate of slurry, and 6 is a transport pipe whose diameter increases as it goes downstream. It is directly connected to the supply device 2. Further, a supply line 5 from the gas supply device 1 is connected to a direct connection line 4 between the slurry supply device 2 and the transport pipe 6.
次にこの作用を説明する。Next, this effect will be explained.

流に行くKつれて管径が犬となっているので、気体のみ
かけ流速の変化を少くすることが出来、流動様式も適切
な状態を保ってスラリーを流すことが出来る。Slurry is pressurized into the transport pipe 3 from the slurry supply device 2 through the direct connection line 4, and at the same time, gas is supplied from the gas supply device 1 through the supply line 5 to the direct connection line 4 for the slurry. Furthermore, after that, the flow rate of the slurry and the flow rate of the gas are adjusted and set so that the flow pattern of the two-phase flow of the gas and the slurry liquid and the apparent flow velocity of the gas at the inlet of the transport pipe 3 are set to appropriate values. In this way, the volumetric flow rate of the gas increases due to the pressure drop downstream of the transport pipe 3, but since the pipe diameter of the transport pipe 6 becomes narrower as it goes downstream, changes in the apparent flow velocity of the gas are prevented. The slurry can be flowed while maintaining an appropriate flow pattern.
尚このとき流動状態はある範囲内にあればよいのである
から、輸送管乙の管径の変化は第2図(alのように連
続的に変化させる必要はなく、第2図(bl及び(cl

うに組合せて連結しても同様の効果が得られる。At this time, since the flow state only needs to be within a certain range, the change in the pipe diameter of the transport pipe B does not need to be changed continuously as shown in Fig. 2 (al), but as shown in Fig. 2 (bl and ( cl
A similar effect can be obtained by combining and connecting pipes with different diameters as shown in the figure, gradually increasing the diameter.
又前記の配管径の変化を多段にわたって行えば微小な流
速制御を行うことも可能である。Furthermore, if the pipe diameter is changed in multiple stages, it is also possible to perform minute flow velocity control.
更に本発明は高粘度のスラリーからレオロジ的性質を有
