Description

本発明は、流体中に混入した汚泥や油等の原流体と密度差のある液体や金属・鉱物・粉塵等の個体を源流体と分離・除去する装置に係わり、遠心力、慣性力、重力などの物理的手法のみを用いて源流体中に含まれる混合物を分離・除去できるとともに、構造が簡単で保守・整備が容易という特性を持つ装置の提供に関する。 The present invention relates to a device that separates and removes liquid, metal, mineral, dust, and other solids having a density difference from a source fluid such as sludge or oil mixed with a fluid from a source fluid, and includes a centrifugal force, an inertial force, and a gravity force. The present invention relates to the provision of a device that can separate and remove a mixture contained in a source fluid using only a physical method such as the above, and has a characteristic that the structure is simple and maintenance and maintenance are easy.

地球上においては流体（気体及び液体）中に様々な混合物が混在している状態が多く存在する。しかし、科学技術分野においては、大気中の粉塵除去、汚水中の汚泥除去、油分に含まれる水分の除去など、源流体に含まれる混合物を除去して、出来るだけ原流体の純度を高める技術が求められている。そこで、近年では、遠心力を利用した遠心分離機による分離方法、慣性力を利用した分離方法、沈殿作用を利用した分離方法及びこれらの組み合わせによる方法が使用されている。   On the earth, there are many states in which various mixtures are mixed in fluids (gas and liquid). However, in the field of science and technology, technologies that remove the mixture contained in the source fluid, such as removing dust in the air, removing sludge in sewage, and removing water contained in oil, to increase the purity of the raw fluid as much as possible. It has been demanded. Therefore, in recent years, a separation method using a centrifugal separator using centrifugal force, a separation method using inertial force, a separation method using sedimentation, and a method using a combination thereof have been used.

これらの方法のうち、例えば、特許文献１、２に記載されている方法では分離を促進させるために薬剤を用いるため、複雑かつ高コストな工程（薬剤投入量の制御を含む複雑な装置と消費薬剤のコスト）を必要とする。 Among these methods, for example, in the methods described in Patent Documents 1 and 2, since a drug is used to promote separation, complicated and high-cost steps (complex apparatus including control of the amount of drug input and consumption of Drug cost).

これに対し、例えば特許文献３、４に記載されているように、薬剤を用いずに遠心力、慣性力、重力、圧力差などの物理的手法のみを用いて混合物を分離・除去できるとの報告もあるが、
源流体中に含まれる混合物を効果的に分離・除去する装置を実用化するためには、構造が簡単（加工が容易でかつ耐久性に優れている）で、保守・整備が容易（メインテナンスフリーに近い）という特性を必要とする。 On the other hand, as described in Patent Documents 3 and 4, for example, it is possible to separate and remove a mixture using only physical methods such as centrifugal force, inertial force, gravity, and pressure difference without using a drug. There are reports,
In order to put into practical use a device that effectively separates and removes the mixture contained in the source fluid, it must have a simple structure (easy to process and excellent in durability) and easy to maintain and maintain (maintenance-free) ).

特開平０７-０００９５７JP 07-000957 特開２００６-２５８４１３JP 2006-258413

しかしながら、一般に、遠心力、慣性力、重力、圧力差などの物理的手法のみを用いて源流体中に含まれる混合物を分離・除去できる装置に、構造が簡単で保守・整備が容易という特性をもたせると、分離能力が低下するとともに、装置が大型化する可能性がある。 However, in general, a device that can separate and remove the mixture contained in the source fluid using only physical methods such as centrifugal force, inertial force, gravity, pressure difference, etc. has the characteristics of simple structure and easy maintenance and maintenance. If provided, the separation capacity may be reduced, and the apparatus may be enlarged.

そこで本発明は、流体中に含まれる混合物が、装置に流入する際に、流体に速度を与えることにより、流れが曲面に沿って流れていく間に遠心力、慣性力という物理的作用が効果的に作用して分離しやすい構造とするとともに、分離した混合物が重力という物理的作用により混合物溜りに集積されるような構造とした。さらに、これらの作用を繰り返すことによって効果的な分離・除去を行えるようにすることを目的とする。 Therefore, the present invention provides the effect of the physical action of the centrifugal force and the inertial force during the flow of the mixture along the curved surface by giving the fluid a speed when the mixture contained in the fluid flows into the device. The structure is such that the separated mixture easily acts and separates, and the separated mixture is accumulated in the mixture pool by the physical action of gravity. Another object of the present invention is to enable effective separation and removal by repeating these operations.

流体貯蔵タンクを出た混合物を含む流体は、循環ポンプを経て分離容器に入り、分離容器から配管（６ｄ）を経て再び循環ポンプの吸入側に至るという循環を繰り返すことにより、効果的に、繰り返し遠心力、慣性力、重力の作用を受けるという構造と機能を持つとともに、
循環ポンプ出口から分離容器に至る配管（６ｂ）及び分離容器内に流入する流体の圧力を、分離容器圧力調整弁により高圧に保つことにより、分離容器内に流入する混合物を含む流体が分離容器内を移動する際に高速を与えることができるという構造と機能を持ち、さらに、
分離容器出口から循環ポンプの吸入側に至る配管（６ｄ）の圧力を、分離容器出口圧力調整弁により設定された圧力に保つことにより、分離容器から流出する混合物を除去された流体が自然流出するとともに、混合物溜りに集積した流体が自然流出するという構造と機能を持っている。 According to the first aspect of the present invention, a fluid storage tank (1) in which a fluid (liquid or gas) containing a mixture is stored, and a pipe (2) connected to a circulation pump (2) connected to the fluid storage tank (1) 6a), a circulation pump (2) installed at the end of the pipe (6a), a pipe (6b) connected to the discharge side of the circulation pump (2) and reaching the separation vessel (4), and a pipe (6b) ), A pipe (6c) branching to the suction side of the circulation pump (2), a separation vessel inlet pressure regulating valve (3) installed in the middle of the pipe (6c), and a pipe (6b). A separation vessel (4) installed at the end, a pipe (6d) extending from the separation vessel (4) to the suction side of the circulation pump (2), and a pressure adjustment in the separation vessel installed in the middle of the pipe (6d). An apparatus for separating a mixture in a fluid, comprising: a valve (5);
The fluid containing the mixture that has exited the fluid storage tank enters the separation vessel via the circulation pump, and effectively repeats by repeating the circulation of returning from the separation vessel via the pipe (6d) to the suction side of the circulation pump. It has the structure and function of receiving the action of centrifugal force, inertia force, and gravity,
By keeping the pressure of the fluid flowing into the separation vessel and the pipe (6b) from the circulation pump outlet to the separation vessel and the pressure of the fluid flowing into the separation vessel high, the fluid containing the mixture flowing into the separation vessel is kept inside the separation vessel. It has a structure and function that can give high speed when moving
By keeping the pressure of the pipe (6d) from the separation vessel outlet to the suction side of the circulation pump at the pressure set by the separation vessel outlet pressure regulating valve, the fluid from which the mixture flowing out of the separation vessel has been removed naturally flows out. In addition, it has a structure and function that the fluid accumulated in the mixture reservoir flows out naturally.

請求項２に記載の発明は、分離容器内において流体（液体及び気体）中に混入した汚泥や油等の原流体と密度差のある液体や金属・鉱物・粉塵等の個体を源流体と分離・除去するために、分離容器は中空で流入口と流出口及び循環用分岐口を持った容器と、それに連結される管及び循環ポンプから構成され、まず、流入口から流入した原液中に含まれる混合物の大部分は、容器内で遠心力、慣性力、重力の作用により原液から分離されて混合物集合部に集められ、下部流出口から分離容器の外に流出する。次に、この一連の動作では分離されなかった混合物は、循環ポンプにより吸入されて循環用分岐口から流出して循環ポンプを経て、流入口に至る管と合流して再び容器内に入り、容器内で遠心力、慣性力、重力の作用により原液から分離されて混合物集合部に集められるという動作を繰り返す。さらに、これらの循環経路を循環する液体や固体よりも密度・質量が小さな混合物は原流体とともに容器内を上昇して上部流出口から分離容器の外に流出する。この一連の動作を繰り返すことにより、流体中に含まれる混合物を効率よく分離・除去することができるという構造と機能を持っている。 According to a second aspect of the present invention, a liquid having a difference in density from a raw fluid such as sludge and oil mixed in a fluid (liquid and gas) and a solid such as metal, mineral and dust in a separation vessel are separated from a source fluid. -For removal, the separation vessel is composed of a hollow vessel having an inlet, an outlet, and a branch for circulation, a pipe connected to it and a circulation pump, and is first included in the stock solution flowing from the inlet. Most of the mixture to be separated is separated from the undiluted solution by the action of centrifugal force, inertia force and gravity in the container, collected in the mixture collecting portion, and flows out of the separation container from the lower outlet. Next, the mixture that has not been separated in this series of operations is sucked by the circulation pump, flows out of the circulation branch port, passes through the circulation pump, merges with the pipe reaching the inflow port, enters the container again, and returns to the container. In the inside, the operation of being separated from the undiluted solution by the action of centrifugal force, inertia force and gravity and collected in the mixture collecting portion is repeated. Further, a mixture having a smaller density and mass than the liquid or the solid circulating in these circulation paths rises in the vessel together with the raw fluid and flows out of the separation vessel from the upper outlet. By repeating this series of operations, it has a structure and function that a mixture contained in a fluid can be efficiently separated and removed.

流体中に含まれる混合物が分離容器に流入する際に、流路を狭くして速度を増加させることにより、流れが分離容器の曲面に沿って常に方向を変化させながら流れていく間に遠心力、慣性力という物理的作用が効果的に作用して分離しやすくするとともに、分離した混合物が重力という物理的作用が働きやすくするための構造と機能を持っている。 When the mixture contained in the fluid flows into the separation vessel, by narrowing the flow path and increasing the velocity, the centrifugal force is applied while the flow is constantly changing its direction along the curved surface of the separation vessel. In addition, the physical action of inertia force effectively acts to facilitate separation, and the separated mixture has a structure and function to facilitate the physical action of gravity.

本発明は、流体（液体や気体）中に混入している源流体と密度差のある流体や固体を、遠心力、慣性力、重力などの物理的な作用のみを用いて効果的に分離・除去できるとともに、構造が簡単（加工が容易でかつ耐久性に優れている）で、保守・整備が容易（メインテナンスフリーに近い）な流体中の混交物除去装置を提供することができる。 The present invention effectively separates a fluid or solid having a density difference from a source fluid mixed in a fluid (liquid or gas) using only physical actions such as centrifugal force, inertial force, and gravity. It is possible to provide an apparatus for removing a mixed substance in a fluid that can be removed, has a simple structure (easily processed and has excellent durability), and is easy to maintain and maintain (close to maintenance-free).

以下に、本発明に係る実施形態について図面を参照しながら説明する。
図１は、本発明の実施の形態に係る流体に含まれる混合物の分離・除去装置の工程の一例を示したフローチャートである。
タンク内に貯蔵された混合物を含む流体は、ポンプにより吸引されるとともに加圧されて分離容器に流入する。
ポンプによって加圧された流体の圧力は圧力調整弁により高圧を保持され、分離容器入口部において流路が絞られることにより高速で容器内に流入する。
容器内に高速で流入した流体は、曲面を移動しながら遠心力、慣性力を受けることにより密度差のある混合物が効果的に分離される。
また、容器内の空間を移動する際に重力の作用により、密度差のある混合物は容器の下部に滞留する。
分離容器内の圧力は、圧力調整弁により大気圧以上に設定されているため、
流体から分離され容器の下部に滞留した比較的密度の大きな混合物は、自然流出できる。
また、流体から分離された比較的密度の小さな混合物は、容器の上部に移動し、自然流出できる。
容器内の中間位置から循環ポンプに吸引された流体は、再び高速で分離容器に流入し、遠心力、慣性力、重力の作用による分離作用を受ける。
洗出口の圧力は圧力調整弁により高圧を保持するため、分離容器に流入する分離から分岐して貯蔵タンクとポンプを接続するするラインに An embodiment according to the present invention will be described below with reference to the drawings.
FIG. 1 is a flowchart showing an example of steps of an apparatus for separating and removing a mixture contained in a fluid according to an embodiment of the present invention.
The fluid containing the mixture stored in the tank is sucked by the pump and pressurized and flows into the separation container.
The pressure of the fluid pressurized by the pump is maintained at a high pressure by the pressure regulating valve, and flows into the container at a high speed by narrowing the flow path at the inlet of the separation container.
The fluid that has flowed into the container at a high speed receives centrifugal force and inertial force while moving on a curved surface, whereby a mixture having a difference in density is effectively separated.
Further, the mixture having a difference in density stays in the lower part of the container due to the action of gravity when moving in the space inside the container.
Since the pressure inside the separation vessel is set to above atmospheric pressure by a pressure regulating valve,
The relatively dense mixture separated from the fluid and stagnating at the bottom of the vessel can flow out naturally.
Also, the relatively low-density mixture separated from the fluid can migrate to the top of the container and flow out naturally.
The fluid sucked into the circulation pump from the intermediate position in the container flows into the separation container again at a high speed, and is subjected to the separation action by the action of centrifugal force, inertia force, and gravity.
Since the pressure at the washing outlet is maintained at a high level by a pressure regulating valve, the line branches off from the separation flowing into the separation vessel and connects the storage tank and the pump.

図２は、本発明の実施の形態に係る流体に含まれる混合物の分離・除去装置の構成の一例を示したブロック線図である。流体の混合物除去装置は、混合物を含む流体（液体や気体）が貯蔵される流体貯蔵タンク（１）と、この流体貯蔵タンク（１）に接続された循環ポンプ（２）に至る配管（６ａ）と、この配管（６ａ）の末端に設置された循環ポンプ（２）と、循環ポンプ（２）の吐出側に接続され分離容器（４）に至る配管（６ｂ）と、この配管（６ｂ）の途中から分岐して循環ポンプ（２）の吸入側に至る配管（６ｃ）と、この配管（６ｃ）の途中に設置された分離容器入口圧力調整弁（３）と、配管（６ｂ）の末端に設置された分離容器（４）と、分離容器（４）から循環ポンプ（２）の吸入側に至る配管（６ｄ）と、この配管（６ｄ）の途中に設置された分離容器出口圧力調整弁（５）から構成されている。 FIG. 2 is a block diagram showing an example of a configuration of a device for separating and removing a mixture contained in a fluid according to an embodiment of the present invention. The fluid mixture removing device includes a fluid storage tank (1) for storing a fluid (liquid or gas) containing the mixture, and a pipe (6a) leading to a circulation pump (2) connected to the fluid storage tank (1). A circulation pump (2) installed at the end of the pipe (6a), a pipe (6b) connected to the discharge side of the circulation pump (2) and reaching the separation vessel (4), and a pipe (6b). A pipe (6c) branching from the middle to the suction side of the circulation pump (2), a separation vessel inlet pressure regulating valve (3) installed in the middle of the pipe (6c), and an end of the pipe (6b). The installed separation vessel (4), a pipe (6d) extending from the separation vessel (4) to the suction side of the circulation pump (2), and a separation vessel outlet pressure regulating valve ( 5).

図３は、本発明の実施の形態に係る流体に含まれる混合物の分離・除去装置の主要部である分離容器の一例を示した概念図である。循環ポンプと圧力調整弁により高圧となった流体は、分離容器入口部分で流路を絞られて速度を増した状態で分離容器に流入する（分離容器内に噴射される）。 FIG. 3 is a conceptual diagram showing an example of a separation container which is a main part of a device for separating and removing a mixture contained in a fluid according to an embodiment of the present invention. The fluid, which has been pressurized by the circulation pump and the pressure regulating valve, flows into the separation vessel in a state where the flow rate is increased by narrowing the flow path at the separation vessel inlet portion (injected into the separation vessel).

分離容器に流入した流体は容器内の曲面に添って移動し、その際に遠心力、慣性力を受けることにより比較的密度が大きな流体（混合物）は内壁に沿って移動し、容器下部に設けられた混合物溜まりに滞留する。 The fluid flowing into the separation vessel moves along the curved surface in the vessel, and the fluid (mixture) having a relatively high density moves along the inner wall due to centrifugal force and inertia force at that time, and is provided at the lower part of the vessel. Stay in the collected mixture pool.

分離容器内に流入した比較的密度の小さい流体（混合物）は、比較的密度の大きな流体（混合物）よりも内壁から遠い位置（中心に近い位置）に移動することにより、容器内の曲面に添って流体（混合物）の密度差による層を生成する。 The relatively low-density fluid (mixture) that has flowed into the separation vessel moves to a position farther from the inner wall (closer to the center) than the relatively high-density fluid (mixture), thereby following the curved surface in the vessel. To create a layer due to the density difference of the fluid (mixture).

その結果、比較的密度差の大きな流体（混合物）は分離容器の下部に滞留し続けることになるが、最下部に設置された流出口２を開放することにより、容器外へ流出する。   As a result, the fluid (mixture) having a relatively large density difference stays in the lower part of the separation vessel, but flows out of the vessel by opening the outlet 2 installed at the lowermost part.

比較的密度差の小さな流体（混合物）は分離容器の上部に滞留するが、循環ポンプにより吸入されることにより容器外へ流出する。   The fluid (mixture) having a relatively small density difference stays at the top of the separation vessel, but flows out of the vessel by being sucked by the circulation pump.

さらに密度差の小さな流体（混合物）は、分離容器の最上部に設置された流出口から容器外へ流出する。   Further, the fluid (mixture) having a smaller density difference flows out of the separation vessel from the outlet provided at the top of the separation vessel.

これらの作用を繰り返し行うことにより、密度の異なる混合物を含む流体は、容器内において密度差により分離されるとともに、分離容器の異なる位置に設置された流出口から容器外へ流出する（流体の混合物が分離される）   By repeatedly performing these actions, the fluid containing the mixture having different densities is separated by the density difference in the vessel, and flows out of the vessel from the outlets provided at different positions of the separation vessel (mixture of fluids). Is separated)

本発明は、流体（液体及び気体）中に含まれる混合物を効果的に分離・除去する場合に適用可能である。   The present invention is applicable to a case where a mixture contained in a fluid (liquid and gas) is effectively separated and removed.
