化生成物溶液から動力回収する場合について説明する。This type of power recovery device can be used in various chemical plants including processes for pressurizing and transporting high 1 royal liquid. Among chemical plants that handle liquids, we will take coal liquefaction plants, which have been rediscovered in recent years due to the deterioration of the petroleum situation, as an example.The plants handle high temperatures and high pressures that contain ash and other mineral particles, which are harsh conditions for valves and other parts in contact with liquids. A case will be described in which power is recovered from a coal liquefaction product solution.

が行なわれる。In this coal liquefaction plant, coal is usually crushed and dehydrated, then a solvent is added to form a slurry (-1), which is pressurized and preheated, then subjected to a liquefaction reaction using a catalyst and hydrogenation. After gas-liquid separation of the coal liquefaction product solution, the pressure is reduced, and after directly or further gas-liquid separation, an operation is performed to fractionally distill the product, heavy and light oil.

操作に悪影響を及はすという問題があった。Conventionally, the pressure reduction of high-pressure liquid was /i! This was done using the throttling effect of the f amount control valve, but in the case of a coal liquefaction product solution,
In view of the fact that solid particles such as ash and catalysts cause significant wear on valve parts in contact with liquid, and that the pressure energy of the liquid during king reduction is wasted as thermal energy, For example, a device was proposed in Japanese Patent Application No. 108365/1983, in which the pressure of the ILF liquid is reduced by changing the volume within the cylinder, and at the same time, the pressure energy is recovered as power. This power recovery device is driven by a high-pressure liquid and is connected to a high-pressure liquid depressurization cylinder that depressurizes and discharges the inflowing high-pressure liquid and is connected to the depressurization cylinder and sucks pressure medium from a pressure barrier tank. A pressure medium elevating ring for pressurizing and discharging a pressure medium; an accumulator disposed in a return flow path from the pressure medium cylinder discharge 1 to the tank; and a pressure medium discharged from the accumulator. It is characterized by consisting of an actuator that converts it into mechanical energy, but since an accumulator is interposed in the power recovery circuit, a throttle valve that controls the speed of the plunger and a gas pressure of the accumulator are used. The problem is that the high-pressure liquid that is supplied to the depressurizing cylinder causes pulsating flow in the depressurizing liquid that is discharged from the depressurizing cylinder, which adversely affects the operation of the chemical plant.

４ａ。In this state, first the liquid supply valve 12 is opened, and then the switching valve 15 is switched to the first position on the left side of the figure, and high pressure coal liquefaction generation is carried out from the high pressure side gas-liquid separation tower 5 to the cylinder 11. The supply of the substance solution is started, and as a result, the plunger lla,
14a is propelled to the right, the pressure medium is increased in pressure, and is transferred from the cylinder 14 to the hydraulic motor 27 via the switching valve 15 and line 42. Is the rotation speed of this hydraulic motor 27 controlled by, for example, an output signal from a sensor 35 that detects the liquid level of the high 11E fl11 gas-liquid separation tower 5? Im+, the cylinder 11 is removed from the gas-liquid separation tower 5.
．． 15 of the coal liquefaction product solution supplied to 16.21!
The amount f is determined by the rotation speed of the hydraulic motor 27, and therefore, even when two or more cylinders 11, 16, 21 perform lap operations, it is possible to prevent pulsating flow from occurring in the coal liquefaction product solution flowing through the line 45. do not have. A motor/generator GM is connected to the liquid motor 27, and the energy of the coal liquefaction product solution converted into the pressure medium U-energy is recovered as electrical energy. When a predetermined amount of coal liquefaction product solution is supplied to the cylinder 11, the switching valve 15 is switched to the neutral position to stop the liquid flow, and then the liquid supply valve 1
2 is closed. Next, the switching valve 15 is switched to the second position (A) on the right side of the figure, and the pressure medium in the pressure medium cylinder 14 is transferred to the line 41, IJ-F valve 301, cooler 3.

When the pressure is increased to the predetermined pressure, the switching valve 15 is returned to the neutral position to complete the 7 ftl pressure stroke, after which the drain valve 13 is opened, and then the switching valve 15 is switched to the second position to complete the drain stroke. is started. In this discharge stroke, the discharge amount is controlled by the signal from the sensor 35 so that the pressure in the line 41 is constant. Due to the action of the pressure medium, plunger 1

イクルの給液行程に移るという動作を繰り返す。11a is propelled to the left, and as a result, the reduced pressure coal liquefaction product solution in the cylinder 11 is transported to the low pressure side gas-liquid separating tower 6 via the line 46 at a predetermined pressure and flow rate. At this time, even if high-pressure pressure medium is discharged from other cylinder systems in the decompression stroke, for example, cylinder 19, to line 41, the discharge amount of pump 29 is controlled accordingly. No pulsation occurs in the liquid flow of 46. When a predetermined amount of coal liquefaction product is discharged from the cylinder 11 in this way, first, the switching valve 15
is returned to the neutral position, and then the drain valve 13 is closed to complete the drain stroke. After the completion of the decrement stroke, the castle,
The valve operation may be simplified by opening the drain valve 13 and entering the drain process as soon as the draining is finished. When the draining process is completed, the pressure of the residual liquid in the cylinder and tick 1 is at line 46.
Because of this, if the high-pressure coal liquefaction product solution is supplied from the liquid supply valve 12 as it is, the solution will suddenly enter the cylinder 11 and give a shock to the piping system.
The Takeda stroke is carried out by switching the switching valve 36 to the second position on the left, supplying high-pressure child medium from the high-pressure liquid supply pump 28 to the cylinder 14, and diverting the remaining liquid in the cylinder 11 to the high-pressure side. This is carried out by increasing the pressure to the same pressure as the pressure inside the gas-liquid separation column 5. When the predetermined pressure is reached, the switching valve 36 again switches to the first position on the right, ends the pressure increase stroke, and repeats the operation of moving to the liquid supply stroke of the next cycle.

In addition, since the valves on the solid particle-containing liquid side and the liquid medium side are arranged on one side of the device, it is possible to shorten the length of one tube.

、前記の場合と同様な効果が得られる。That is, in this embodiment, the plunger type cylinder 47.4 is used as a U-pressure actuator with a flow rate control mechanism.
8.49 and plunger-type cylinders 54, 55, and 56 disposed opposite to each cylinder, during the liquid supply stroke of each cylinder 11, 16, and 21, for example, during the liquid supply stroke of cylinder 11. During the stroke, the high-pressure power medium discharged into the line 42 is transferred to the cylinder 4 via the switching valve 50.
7, the pressure of the coal slurry in the cylinder 54 is increased, and the coal slurry is recovered as power to be supplied to the coal slurry supply line 7, so that the coal slurry boost pump 2 can be used for a short time or is not needed. When the pressure reduction section in the blunt uses the recovered power to boost the pressure of the coal slurry in the pressure increase section of the blunt, even if it is far away, the pressure caused by the clean pressure medium fluid, e.g. the solvent for producing the coal slurry, the working fluid The only difference is that the pressure energy of the high-pressure liquid is efficiently returned directly using the transmission means.
The other parts are the same as those in FIG. In this embodiment as well, the same effects as in the above case can be obtained.
