Description
Technical field
The utility model relates to the technical field of liquid gas conveying, particularly, relates to a kind of liquid gas and to vaporize transporting system from supercharging.
Background technique
At present, the gasification delivery method of liquefied gas at low temp (as liquid nitrogen, liquid oxygen, liquid argon, liquefied ammonia, liquid chlorine and LNG Liquefied natural gas etc.) is greatly to there being two kinds: the first utilizes the outer energy such as the motor etc. that supplies to drive liquor pump, liquid is forced to be pressurized to certain pressure, (vaporizer a kind ofly absorbs the device that external heat makes cryogenic liquid vaporizer to send vaporizer to, several forms such as free bath formula, water-bath type or latent combustion) after vaporization, along Cemented filling to user; The second is that the low-temp low-pressure liquid gas in basin enters pressurized machine under gravity, tank top is entered again after utilizing pressurized machine absorbing environmental heat to make liquified gas vaporization, the pressure of liquid gas in basin is raised, then by the liquefied gas at low temp press-in vaporizer in basin.
Wherein, the first gasification delivery method roughly has these two kinds of common type of Fig. 1 and Fig. 2.As shown in Figure 1, Fig. 1 is the schematic diagram of existing electric piston pump supercharging vaporization transportation of liquefied gas, is usually used in medium-sized supply station and high pressure bottling station.Motor 11 increases after torque through gearbox, driving crank rotarily drives connecting rod and promotes reciprocating pump 10, is pumped by the low-temp low-pressure liquid gas in basin 1, forces in feeding first vaporizer 3, first vaporizer 3 absorbing environmental heat, by after liquified gas vaporization, is sent in user's pipe network 6.Wherein, feed flow and pressure change motor 11 rotating speed by frequency variator 12 and change.
Figure 2 shows that the schematic diagram of existing immersed pump supercharging vaporization transportation of liquefied gas, be usually used in large-scale supply station as LNG liquefied natural gas supplying station.Immersed pump 14 is put into bottom pump sump 15, and the gravity of immersed pump 14 backs down weight valve 13, and the low-temp low-pressure liquid gas in basin 1 pours in pump sump 15; Liquid gas pumps after starting by immersed pump 14, forces in feeding first vaporizer 3, and the first vaporizer 3 absorbing environmental heat, by after liquified gas vaporization, is sent in user's pipe network 6.Wherein, feed flow and pressure change motor speed to change by frequency variator 12.
The shortcoming of the first gasification delivery method is: 1) need people to carry to energy to increase the pressure of liquid gas; 2) when carrying inflammable and explosive liquid gas with motor (such as motor), likely the security incident such as fire or blast can be caused; 3) pressure and flow regulator more complicated, such as regulate and control with frequency variator with during electrical energy drive, when can drive with other, need artificial regulatory be used.In addition, as shown in Figure 1, easily to external leakage, not only there is waste in the motive sealing of reciprocating pump 10, and unfriendly to environment, there is potential safety hazard.Further, because motive sealing place of reciprocating pump 10 is in communication with the outside, there is a small amount of air to enter from motive sealing and be transferred in gas, pollute and be transferred gas, thus the gas that purity requirement can not be carried high.
The second gasification delivery method as shown in Figure 3.First, open the second modulating valve 18, the liquefied gas at low temp in basin 1 enters in pressurized machine 16 under gravity, gets back to the top of basin 1 after pressurized machine 16 absorbing environmental heat makes vaporizing liquid along pipeline, increases the vapour tension of the liquid gas in basin 1; After opening the first modulating valve 17, the liquid gas bottom basin 1 under pressure, enters in the first vaporizer 3, sends into user's pipe network 6 after the first vaporizer 3 absorbing environmental heat makes liquified gas vaporization.Wherein, gas supply flow is controlled by the first modulating valve 17, and supply gas pressure is controlled by the second modulating valve 18.
The shortcoming of the second gasification delivery method is: 1) liquid gas liquid storage tank must be able to bear than user with the more taller pressure of atmospheric pressure; 2) volume of basin is generally smaller, only has several cubic metres to tens cubic metres; 3) basin pressure-bearing is higher, and its cost is higher; 4) because of the limited pressure that basin can bear, the highest also less than 2.0MPa, therefore fed distance can not be too far away, and quantity delivered is also little; 5) peer machine is equipped with complicated automatic pressure regulating device, but the acoustic-optic alarm that large portion system is only equipped with pressure monitoring carries out manual voltage regulation to remind operator.

Technique scheme makes liquified gas vaporization and supercharging by the first vaporizer 3 absorbing environmental heat, while dividing device of air 4 that the liquid gas after vaporization is sent into user's pipe network 6, also the drive part Q liquid gas after vaporization being sent into supercharging device 2 drives the compression portion Z of supercharging device 2 to draw and pumping liquefied gas (pressure of liquid gas can increase to 0.4 ~ 21MPa), thus realizes from pressure-increasing unit by being transferred gas.The technical solution of the utility model only needs the first vaporizer absorbing environmental heat energy, and do not need other any energy and device to drive, do not need motor, there is no power supply, burning things which may cause a fire disaster and thermal source, when carrying inflammable and explosive liquid gas, do not have the security incident causing fire or blast.Further, utilize and be transferred gas-powered supercharging device 2, be transferred gas purity and do not have any change, thus can high-purity gas be carried.In addition, basin 1 not to need to bear than user with the taller pressure of atmospheric pressure, keeps routine storage pressure (about 0.015MPa) of liquid gas; The volume of basin 1 can be large enough to a few kilostere, and the cost of unit volume is low; And discharge pressure up to more than 15MP, can carry out long-distance sand transport, and the bottling of pressure up to the oxygen of 15MP, nitrogen, argon gas that can be used for bottling.
As shown in Figure 4 and Figure 5, as one preferred embodiment, the position of liquid gas of the present utility model on the pipeline that supercharging vaporization transporting system is also included between the second outlet and drive part Q and between inlet 7 and drive part Q is provided with that the second vaporizer 5, second exports, the second vaporizer 5 is communicated with successively with drive part Q.When initial start-up, from the liquid gas without vaporization that inlet 7 injects, these liquid gas are vaporized in the second vaporizer 5, then enter the drive part Q of supercharging device 2, thus drive compression portion Z draw the liquid gas in basin 1 and carry out supercharging pumping to liquid gas.After the liquid gas entering the first vaporizer 3 is vaporized, a part enters to user's pipe network 6 along pipeline, and another part enters the second vaporizer 5, so circulates, and reaches the object of lasting external air feed.At normal operating condition, the second vaporizer 5 makes vaporizing liquid re-vaporize, and volume continues to increase, and pressure also increases many, and temperature reaches normal temperature.If when what user required is less than 1MPa with atmospheric pressure, the second vaporizer 5 can not be established.
Wherein, as shown in Figure 5, device of air 4 is divided to comprise the first reduction valve 41 and the second reduction valve 42, the outlet of the first reduction valve 41 and the first outlet and the outlet of the second reduction valve 42 and the second outlet, the entrance of point device of air 4 is communicated with the entrance of described second reduction valve 42 with the entrance of the first reduction valve 41 respectively.The outlet pressure of the first reduction valve 41 and the second reduction valve 42 is set to predetermined value, thus the system of guarantee internal pressure is basicly stable, realizes pressure and automatically regulates.Particularly, supercharging device 2 inherently has the function of pressure regulation and tune amount because the first reduction valve 41 of point device of air 4 and the second reduction valve 42 to separate gas pressure be substantially invariable, these gases are to the driving force of supercharging device 2 also substantially constant.When the pressure in the first vaporizer 3 raises, the working resistance of supercharging device 2 also increases thereupon, and its operating rate also can slow down thereupon, then quantity delivered reduces thereupon, when resistance and driving force balance, supercharging device 2 can quit work automatically, thus realizes the object of automatic Regulation and tune amount.
Wherein, the outlet pressure of the first reduction valve 41 is less than the outlet pressure of the second reduction valve 42, thus makes to flow out and the gas flowing through drive part Q can enter user's pipe network 6 from the second reduction valve 42.In the present embodiment, the outlet pressure of the first reduction valve 41 is set as 3.0MPa, the outlet pressure of the second reduction valve 42 is set as 3.5MPa, from the second reduction valve 42 gas out because of temperature step-down after step-down, but after entering the further heat absorption of the second vaporizer 5, temperature rises again and gets back to close to ambient temperature.When this strand of gas enters drive part Q, pressure can reach 3.5MPa, and the outlet side pressure that drive part Q is communicated with user's pipe network 6 is close to 3.0MPa, so close under the differential pressure action of 0.5MPa, drive part Q does work and also the gas in drive part Q is clamp-oned user's pipe network 6.
Further, as shown in Figure 5, drive part Q comprises commutator 21, actuator chamber 22 and is located at the driven plunger 23 (preferably setting the area after its end Area subtraction piston rod 26 described later sectional area as 900 square millimeters) in actuator chamber 22.Actuator chamber 22 comprises first of the both sides being located at driven plunger 23 respectively and drives gas port Q1 and second to drive gas port Q2, and the outlet of the second vaporizer 5 first drives gas port Q1 and second to drive the another one in gas port Q2 to be communicated to user's pipe network 6 through commutator 21 through commutator 21 and first drives gas port Q1 and second to drive the one in gas port Q2 to be communicated with while.Gas from the second vaporizer 5 enters the side (pressure can reach 3.5MPa) of the driven plunger 23 of drive part Q, and first of the opposite side of driven plunger 23 drives gas port Q1 or second to drive gas port Q2 to be communicated with (pressure is close to 3.0MPa) with user's pipe network 6, so close under the differential pressure action of 0.5MPa, driven plunger 23 moves from high side to low side, and the gas of low voltage side is clamp-oned user's pipe network 6 by driven plunger 23.
And compression portion Z comprises booster cavity 24, charged piston 25 (preferably setting its face area as 100 square millimeters) and piston rod 26, booster cavity 24 is located at one end of actuator chamber 22, one end of piston rod 26 is connected with charged piston 25 and the other end is connected with driven plunger 23, booster cavity 24 comprises the first supercharging opening Z1 and the second supercharging opening Z2 of the both sides being located at charged piston 25 respectively, first supercharging opening Z1 is communicated with basin 1 with the first vaporizer 3 respectively, and between the first supercharging opening Z1 and basin 1, be provided with the first one-way valve D1 making fluid only can flow to the first supercharging opening Z1 from basin 1, the the second one-way valve D2 making fluid only can flow to the first vaporizer 3 from the first supercharging opening Z1 is provided with between first supercharging opening Z1 and the first vaporizer 3.
Through the liquid gas that the second vaporizer 5 is vaporized, the left side (or right side) of the driven plunger 23 of supercharging device 2 is entered from the suction port of commutator 21, promote driven plunger 23 (or left) motion to the right, right side (or left side) the interior gas of actuator chamber 22, through the air outlet of commutator 21, enters user's pipe network 6.Simultaneously, the movement of driven plunger 23 drives the movement of charged piston 25 by piston rod 26, and the side making booster cavity 24 inner volume increase forms negative pressure, thus the liquid gas in suction tank 1, then the liquid gas of suction is pressed into the first vaporizer 3 (pressure being pressed into the liquid gas of the first vaporizer 3 can up to 4.5MPa) by the reverse movement (charged piston 25 moves under the drive of driven plunger 23) of charged piston 25.In the present embodiment, the end face useful area 9 of driven plunger 23 is preferably set doubly to the end area of charged piston 25.Because there is piston rod 26 between driven plunger 23 and charged piston 25, the axial force of liquid effects on charged piston 25 that gas can be acted on axial force in driven plunger 23 and liquid gas is transmitted mutually.If do not consider the words of the frictional force between part parts, according to the law that pressure and area are inversely proportional to, the pressure that the medium (liquid gas) that so charged piston 25 acts on it can produce is 4.5MPa (9 times of areas are multiplied by the pressure reduction (0.5MPa) of driven plunger 25 both sides).Wherein, under the acting in conjunction of the first one-way valve D1 and the second one-way valve D2, ensure that liquid gas only can flow to the first vaporizer 3 from basin 1, and can not reverse flow.
