Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, waste liquid such as bilge water in a double bottom engine room in a ship has been treated using a complex combination of reciprocating pumps, tanks and centrifugal separation.

However, the transfer separation device such as the reciprocating pump described above may be damaged by solids (iron powder, etc.) in the waste liquid, and may be forced to suspend operation due to these solids, and in some cases may be damaged as described above. In some cases, it was necessary to replace all parts. Furthermore, since the sliding part of the reciprocating pump and the like is also the bale liquid part, accidents such as getting caught in solids in the waste liquid have occurred, making it difficult to use the pump stably for a long period of time. The present invention was proposed in order to solve the above-mentioned conventional drawbacks, and a jet obtained by injecting pressurized fluid from a nozzle is blown into the center of the Venturi, and the vacuum generated around the center absorbs the fluid to be treated. With a simple structure that has the minimum number of moving parts, it discharges the fluid along with the jet and at the same time uses the jet's surplus energy to convert the fluid to be treated (mixed fluid that requires separation) into three states (solids) at once. The purpose of the present invention is to provide a transfer and separation device that is capable of separating oil into oil, heavy oil, water vapor, etc.), is highly reliable, and has an excellent operating rate.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a transfer and separation device showing an embodiment of the present invention, and is composed of a transfer device 1 and a separation device 2. As shown in FIG.

The transfer device 1 includes a nozzle 4 that injects a pressure fluid 3a or 3b.
At the same time, the fluid to be treated 5 is placed near the nozzle 4.
It consists of a Venturi tube 7 installed so that the opening 6a of the suction pipe 6 that sucks in the fluid 3a or 5b is located, and when the pressure fluid 3a or 3b is injected from the nozzle 4 into the throat 8 of the venturi tube 7, the The vacuum generated in the peripheral portion 9 causes the fluid to be treated 5a or 5b to be sucked in from the suction pipe 6. Note that the fluid to be treated 5a is a fluid to be treated in the case of liquid, and the pressure fluid used in this case is 3.
Indicated by a.

Further, the processing fluid 5b is assumed to be a fluid to be processed in the case of gas, and the pressure fluid used in this case is indicated by 3b. Here, the fluid to be treated 5a is, for example, drain generated inside a ship, and is a suspension in which iron powder (iron rust, etc.), peeled paint, etc. are mixed in with oil and water. On the other hand, the pressure fluid 3a includes, for example, compressed air (9 to 30k9/) inside the ship,
Diesel engine cleaning air (2k9/c fin, 180oo
), exhaust steam (4k9/ground, 150oo), etc. are used, and even if the fluid to be treated 5a has viscosity, it is heated by the thermal energy of the pressure fluid 3a, and by being placed on the jet flow, it becomes fine. and becomes easy to separate.

The pressure fluid 3b has a relatively lower fog point than the fluid to be treated 5b, and is an inert liquefied gas pressure fluid. Note that the separation accuracy and the injection speed of the pressure fluid are designed according to the required degree, and the separation accuracy can be adjusted by adjusting the supply amount of the pressure fluid after the design. Next, in the separation device 2, the outlet part of the venturi tube 7 is tangentially connected to the cylindrical container 11 (separator 10), and the solid material separation rotor 12 provided inside the cylindrical container 11 is connected to the solid material separation rotor 12. The receiving structure, that is, the entire circumference of the inner wall of the B part of the cylindrical container 11,
An annular portion 13a formed of a mesh body provided at a predetermined distance from the inner wall of the container, and the annular portion 13a connected to the cylindrical container 11.
A conical container 14 is attached to the lower outer surface of a conical container 14 whose lower end is reduced and the lower end of the cylindrical container 11 is closed. The processing fluid 5 consisting of a heat transfer tube 15
It consists of heating means a or 5b and an exhaust pipe 16 provided vertically at the center of the cylindrical container 11. Note that the cylindrical container 11 does not need to be a cylinder, and may be a cylindrical container of another shape. The exhaust pipe 16 is disposed within the inner periphery of the solid separation rotary blade 12 with a slight spacing therebetween, and discharges the gas inside the conical container 14 upward.

Further, the rotary blade 12 is rotatably supported by a bearing 18 (rolling bearing, oil-less bearing, etc.) supported by three supports 17 attached to the lower part of the exhaust pipe 16 via its spokes 19. ing. Note that the gas in the conical container 14 passes between the spokes 19 and rises into the exhaust pipe 16. Here, the rotor blade 12 rotates as the fluid flowing from the outlet of the Venturi tube 7 into the container 11 from the tangential direction swirls, but the rotational speed of the rotor blade 12 is microscopically This is slower than the velocity of the swirling flow of the fluid.

The shape of the rotary blade 12 is designed so that this speed plays a role in repelling suspended matter (light solid matter, etc.) to the outside. The temperature in the cylindrical container 11 is determined from the pre-processing state to either the heating side or the cooling side, depending on the properties of the fluid to be treated 5a or 5b and the purpose of separation.

When the processing fluid is a liquid like 5a, it is first heated to 100 qo or more (especially inside the heat transfer tube and its fins, etc.), and the heat transfer tube 15 is heated with the same fluid as the pressure fluid 3a. do. On the other hand, in the case of the fluid to be treated 5b, it is cooled using the same fluid 3b. 20 is a heat exchanger tube 15
The fins 20 are arranged on the inner wall surface of the conical container 14 in the part where the heat exchanger tubes 15 are arranged. It constitutes heating means for the fluid to be treated.

Reference numeral 21 is a transparent body such as glass that is iron-cast in a window provided on the side surface of the cylindrical container 11, and the interior can be monitored from the outside through the transparent body 21, and maintenance and inspection can be performed by removing it. It looks like this.

Next, the action will be explained.

(1) When the processing fluid is liquid. A jet obtained by injecting the pressurized fluid 3a from the nozzle 4 is blown into the throat 8 of the Venturi tube 7, and the fluid 5a to be treated is sucked from the suction pipe 6 by the vacuum generated around the throat 8. This is then atomized by the jet and sent into the cylindrical container 11 through the Sekiguchi 10 section. The sent fluid to be treated flows into the cylindrical container 11 from a tangential direction as indicated by an arrow 21a, and descends in a spiral shape. At this time, the solid matter separation rotor 12 rotates with the support of the bearing 18 due to the swirling fluid, and the solid matter 22a such as iron powder mixed in the fluid is thrown away to the outside.

Fluid is also blown to the outside together with this solid matter 22a, but these are deposited on the strainer net 13, and among them, the fluid is
As shown in 3a, it is surrounded by a mesh of strained silk 13 and descends. The evacuated fluid descending as shown by arrow EP28a is collected in the conical container 14, and water content is evaporated by the action of the heat exchanger tubes 15 and fins 20 provided on the outer surface of the conical container 14. The evaporated water vapor rises as shown by the arrow 24a,
It enters the exhaust pipe 16 between the spokes 19 and is discharged.
On the other hand, a separated liquid 25a from which solid matter 22a and water etc. have been removed
is taken out from the opening at the lower end of the conical container 14 as shown by the arrow. (0) When the fluid to be treated 5b is a gas.

The inert liquefied gas isopressure fluid 3b, which has a relatively lower dew point than the fluid to be treated 5b, is blown into the throat 8 of the Venturi tube 7 from the nozzle 4 as a jet, and the vacuum generated around the throat 9 causes the fluid to flow from the suction pipe 6. , relatively pressure fluid 3b
The fluid to be treated 5b having a higher fog point is inhaled. Then, while cooling this with the jet from the opening low part 0,
It is fed into the cylindrical container 1 from the tangential direction as shown in 1b. In this way, the fluid 5b to be treated enters the cylindrical container 11, and descends while being further cooled while spiraling. At this time, the solid matter separation rotor 12 also rotates along with the vortex, and the solid matter 22b and the like are thrown out.

This repelled solid material 22b is deposited on the strained silk 13 together with the fluid in the section, and the fluid is passed through the mesh 1 trowel of the strained silk 13, further descends as shown by the arrow E023b, and enters the conical container 14. Can be collected. The fluid collected in the conical container 14 is cooled by the action of the heat transfer tubes 15 and fins 20, and the fluid with a relatively high dew point is condensed. The fluid with a low dew point rises in a gaseous state as shown by the arrow E024b and is discharged from the exhaust pipe 16. The condensate from which suspended solids have been removed in this manner is taken out as indicated by arrow 25b. Furthermore, when there are many types of suspended substances in the fluid to be treated, the above (1) and (0)
It is possible to carry out transport separation by combining the following cases.

As explained in detail above, according to the present invention, pressurized fluid is injected from the nozzle into the Venturi tube, the fluid to be treated is sucked by the vacuum generated around the nozzle, and the fluid is further transferred along with the jet to the cylindrical container of the separation device. can do.

Therefore, the rotor blade for separating solids installed inside the cylindrical container is
It rotates with the swirling flow of the jet and expels solid matter in the fluid to be treated to a receiving structure around the rotor blade. Therefore, according to the present invention, it is possible to separate the treatment of mixed fluids such as car oil, moisture, and solids (metal pieces, etc.) into three types (three states of matter) at once with a simple structure. . If the fluid separated from the solids is a liquid, the water is evaporated and removed by the heating means, and the solids and separated liquid are separately taken out to the outside.

When the fluid is a gas, the fluid with a relatively high fog point is first condensed by the cooling means, and the gas that does not condense is discharged from the gas outlet. In this way, the device of the present invention has no precise moving parts and has a simple structure, so it can be expected to operate semi-permanently, and the power source can be, for example, steam or compressed air that is standard onboard ships. Since this method can be used, it is possible to perform continuous separation treatment of the fluid to be treated very economically.
In addition to being a driving source for transporting the fluid to be treated, the pressure fluid can also be used for heating or cooling depending on the type of fluid to be treated.Furthermore, this device can be combined in multiple stages and the fluid in the heat transfer tubes can be controlled. Multiple types can be separated, and depending on the properties of the separated liquid, it can be reused as is. Therefore, even with a filter method that uses magnets, there is a limit to the separation of suspended solids mixed in the fluid to be treated.However, according to the present invention, moving parts are kept to a minimum to improve the operating rate of the equipment and meet the requirements. This has the effect of making it possible to provide a highly reliable device that can easily achieve separation accuracy of 1. The present invention can be applied to transportation and separation devices for acidic, alkaline fluids, and fluids that suspend solids.
