The specific embodiment
Now with reference to accompanying drawing, explain the preferred embodiment of the present invention.
Fig. 1 is the structure chart of the basin pipeline in ship, and to illustrate that Fig. 2 is the cutaway view that is applied to injector of the present invention for reducing the equipment of the VOC of ship, and Fig. 3 is the cutaway view that the basic structure that is applied to pressure regulator valve of the present invention is shown.
As shown in Figure 1, being ship, is especially in the situation of oil carrier, in order to prevent basin 100 blasts, by IG pipeline (inert gas pipeline), sprays inert gas, thereby controls the concentration of oxygen.
In this case, in the present invention, by the method for induction and pressurization gas mixture, making all VOC in basin 100 is all the VOC of the condensation more than saturated vapour pressure, thereby reduces the generation of VOC.
Conventionally, be widely used the injector that utilizes Venturi effect.
This injector 300 is by being sent to the liquid of suction side or gas predetermined altitude above or being generally used for discharging swimmingly by the vacuum phenomenon producing at a high speed liquid or the gas that is positioned at suction side by utilizing.
In the present invention, injector 300 is for by the admixture of gas supercharging of inert gas and VOC and be sent to the base portion of basin 100, thus condensation VOC.
For this reason, the present invention includes the pressure regulator valve 400 at the port of export place that is arranged on injector 300.
Pressure regulator valve produces pressure at entrance side, pressure is remained on the saturated vapour pressure of liquid goods thus.For this reason, pressure the reception by measuring nose portion comes the pressure signal of self-controller 500 to control the stroke of pressure regulator valve 400.
And the outlet side of pressure regulator valve 400 is connected with the base portion of basin 100, therefore, if in the inner water-head that forms of basin 100, the VOC of evaporation can be fully condensed by water-head.
Meanwhile, because the amount of the liquid goods in basin 100 can according to circumstances become, therefore, if uneasiness is debug pressure valve 400, the unsettled liquid goods of discharging from the outlet of injector 300 may produce continuously VOC basin 100.
Yet because the present invention keeps the pressure of the front end of pressure regulator valve 400 equably, therefore, if the liquid goods in basin 100 is prepared so manyly so that introduce pipeline and discharge pipe can be submerged, VOC can be fully condensed.
That is, as shown in Figure 2, the one end, left side that is applied to injector 300 of the present invention is connected with oil pump, and the other end relative with the one end being connected with oil pump is connected with the entrance side of pressure regulator valve 400.
In this case, IG pipeline 200 along the radial skew of injector 300 connect, thereby separated with one end connected with oil pump but engage with outermost outlet side.
Thereby, when injector 300 operation, at the point by with the oil combination of discharge at a high speed (, " A " some place in figure) top directly forms vacuum, then, the liquid goods of discharging from the introduction pipeline being connected with oil pump and the mixture of the inert gas of introducing under vacuum state and VOC are mixed together and are sent to outlet, therefore can keep sufficiently high pressure, and the pressure of outlet side can be remained on the saturated vapour pressure of liquid goods.
Simultaneously, because the pressure of the outlet side of injector 300 is variable according to the situation of rearward end (back pressure etc.), therefore, in fact, only utilize injector 300 to be difficult to pressure to remain on predetermined pressure, and therefore as mentioned above, pressure regulator valve 400 is arranged on part place as shown in Figure 3, to evenly and continuously keep the pressure of the outlet side of injector 300.
As shown in Figure 3, pressure regulator valve 400 comprises trim portion 430, and this trim portion 430 is arranged on leading section 410 places of runner.
Trim portion 430 forms column, and has a plurality of holes.
In this case, trim portion 430 prevents that unexpected pressure from changing, and when fluid motion, at leading section 410 and rearward end 420 places, this unexpected pressure variation may occur.When there is such phenomenon, a part for the fluid of the hole separation by trim portion 430 makes it possible to prevent that unexpected pressure from changing.
In other words, the in the situation that of common valve, because unexpected pressure reduction may cavitations occur at rearward end 420 places, and the generation of such cavitation and vacuum is the same and the phenomenon that causes internal flow to evaporate because of vacuum, and therefore final promotion is included in the generation of the VOC in fluid.
Yet, the invention is characterized in that fluid passes trim portion 430, thereby keep equably the pressure of leading section 410.
And the dish 440 being connected with gear operates by driving shaft 450, and can move along the mobile direction of fluid.In this case, regulate like this pressure, if that is: the pressure ratio setting pressure of leading section 440 is low, coil 440 closed front portions 410, and if the pressure ratio setting pressure of leading section 410 is high, coil 440 and open leading section 410.Driving shaft 450 is by the drive source operation such as hydraulic cylinder or motor.
In this case, pressure regulator valve also comprises pressure measurement sensor (not shown), this pressure measurement sensor is arranged on leading section 410 and with controller 500 and is connected, and makes in order to keep equably controller 500 control panels 440 described in pressure, thereby automatically controls the aperture of runner.
As mentioned above, according to VOC of the present invention, reduce equipment and can keep being equably supplied to the pressure of basin 100 by the pressure regulator valve 400 that is arranged on the outlet side of injector 300, make VOC reduce equipment and can make the evaporation of VOC minimize, that is, and by making VOC condensation that the generation of the VOC in ship is reduced.
