In addition, the shape and size of the elements in the drawings may be exaggerated for clarity.

The gas supply facility according to the present invention refers to a facility for supplying a gas utilization facility (for example, a building, a manufacturing facility, or a manufacturing process, etc.) made of gas by vaporizing a liquefied gas or liquefied volatile chemical.

In addition, liquefied gas or liquefied volatile chemicals are used in the gaseous state as 'gas' or 'gas', and the liquid state is used as the term 'liquid' or 'raw material'.

In addition, in the present invention, liquefied gas basically means liquefied petroleum gas (Liquefied Petroleum Gas). However, the present invention is not limited thereto and may be applied to the supply of any gas that can be liquefied.

1 is a partial cross-sectional view schematically showing a gas supply facility according to an embodiment of the present invention, Figure 2 is a view schematically showing the structure of the gas supply facility shown in FIG.

1 and 2, the gas supply facility according to the present embodiment includes a storage tank 50 and a gas supply module 60.

The storage tank 50 stores the liquefied gas therein, and may be provided with one or more.

The storage tank 50 may be formed of various materials and shapes as long as it can withstand the pressure and temperature of the liquefied gas stored therein.

In this embodiment, the storage tank 50 can store about several tons to several tens of tons (eg 20 to 70 tons) of liquefied gas. However, the configuration of the present invention is not limited thereto.

The storage tank 50 stores the liquefied gas in a liquid state through the supply tank 90 or the like, but then, as the temperature rises, the liquefied gas is evaporated and phase-changed into a gaseous state, such that liquid and gas coexist inside.

The storage tank 50 may include a level gauge (not shown) and a pressure safety valve (PSV) capable of knowing the storage capacity of the liquefied gas. In addition, the storage tank 50 is spaced apart from the gas supply module 60 to be described later, it is connected to the gas supply module 60 through a plurality of pipes.

Meanwhile, in this embodiment, only one storage tank 50 is illustrated and described, but a plurality of storage tanks 50 may be provided as necessary. In this case, the storage tanks 50 may be connected in parallel to each other.

The gas supply module 60 includes a frame 5, a vaporizer 10, a heater 20, a pressure regulator 30, and a pneumatic supply 40 disposed inside the frame 5.

The frame 5 functions as a pedestal so as to support components such as the vaporizer 10, the heater 20, the pressure regulator 30, and the pneumatic supply 40. The upper part of the frame 5 can be divided into a number of zones for easy storage of the components. In this case, each zone may be divided into a partition or a frame, but is not limited thereto.

The frame 5 is formed to have a size that can be transported through the road, and is formed of a material having rigidity capable of firmly supporting the above components. For example, the frame 5 may be formed of a metal material, but is not limited thereto.

Although not shown, a gas detector may be installed in the lower space of the frame 5 to detect when liquefied gas is leaked.

The vaporizer 10 receives the liquefied gas in a liquid state from the storage tank 50 and heats it with a heating device to vaporize it, and then supplies the vaporized gas to the first supply pipe 13.

One or more vaporizers 10 may be provided, and each vaporizer 10 may be provided with a temperature indicator (not shown) and a flow control unit C4 capable of displaying and controlling temperature.

The heating device 11 of the vaporizer 10 is used to convert the liquid into a gas. In the present embodiment, the heating device 11 uses an electric heater. However, the configuration of the present invention is not limited thereto, and various modifications are possible, such as using hot water or steam as the heating device 11.

The heating device 11 of the vaporizer 10 is controlled by the first pressure control unit C1. The first pressure control unit C1 controls the heat source supplied to the heating device 11 of the vaporizer 10 based on the pressure in the second supply pipe 23. For example, when the gas pressure in the second supply pipe 23 is higher than the preset pressure, the first pressure control unit C1 lowers the set value of the vaporizer 10 heating device 11 to reduce the amount of gas vaporized. When the gas pressure is lower than the preset pressure, the set value of the heating device 11 may be increased to increase the amount of gas vaporized.

Accordingly, the pressure of the gas supplied to the gas utilization facility 80 through the first and

second supply pipes

13 and 23 can be kept constant.

In addition, the vaporizer 10 according to the present embodiment has a storage space 15 for temporarily storing the liquid. More specifically, the vaporizer 10 stores and vaporizes a certain amount of liquid liquefied gas (or volatile chemical) in the storage space 15. Therefore, the liquefied gas supplied from the storage tank 50 is first stored in the storage space 15 of the vaporizer 10, and then vaporized and supplied to the first supply pipe 13.

As the storage space 15 is provided in the vaporizer 10 as described above, even if an abnormality occurs in the storage tank 50 or the liquefied gas stored in the storage tank 50 is exhausted, the storage space 15 of the vaporizer 10 is temporarily removed. Gas can be supplied to the gas utilization facility 80 using the liquefied gas stored in the). Therefore, the gas can be continuously supplied to the gas utilization facility 80 even while the storage tank 50 is repaired or the open inspection of the storage tank 50 is performed.

The flow rate control unit C4 controls the amount of liquefied gas flowing into the storage space 15 of the vaporizer 10. For example, the flow rate control unit C4 detects the level of the liquefied gas stored in the storage space 15, and closes the valve 14 installed in the liquid supply pipe 12 when the flow rate control unit C4 is above a predetermined level. In addition, the valve 14 may be opened when the level is lower than or equal to a predetermined level.

At least one heater 20 is disposed at the rear end of the vaporizer 10 to heat the gas supplied from the vaporizer 10.

When the heater 20 is omitted, the gas transferred from the vaporizer 10 may be condensed into liquid because the temperature decreases while passing through the first supply pipe 13 and the second supply pipe 23. This problem can be exacerbated in winter when the air temperature is low.

Therefore, the gas supply module 60 according to the present embodiment arranges the heater 20 between the first supply pipe 13 and the second supply pipe 23 to adjust the temperature of the gas supplied to the gas utilization facility 80. Keep it.

On the other hand, in the summer when the atmospheric temperature is high, since the internal temperature of the gas supply module 60 is also high, gas does not easily condense even without passing through the heater 20. Therefore, in this case, the heater 20 is configured to bypass the heater 20 through the bypass pipe 25 without passing through the heater 20. The path selection of the bypass pipe 25 and the heater 20 may be made through the operation of the valve 27 disposed at the front end of the bypass pipe 25 and the heater 20. Here, the operation of the valve 27 can be made automatically based on the outside temperature. However, the present invention is not limited thereto, and the operator may manually operate it.

In the present embodiment, the heater 20 may use at least one of an electric heater, steam, and hot water as the heating means 21. In addition, the heating means 21 of the heater 20 is controlled by the temperature control unit C3. The temperature control unit C3 senses the temperature of the gas discharged from the heater 20 and controls the temperature of the heating means 21 based on this.

For example, the temperature control unit C3 increases the temperature of the electric heater when the temperature of the gas discharged from the heater 20 to the second supply pipe 23 is equal to or lower than a preset temperature (eg, 50 ° C.), and sets the temperature. If it is abnormal, it can control so that the temperature of an electric heater may be lowered.

The pressure regulator 30 includes a pressure equalizing pipe 32 and a second pressure control unit C2.

One end of the equalization pipe 32 is connected to the storage tank 50, and the other end is connected to the first supply pipe 13 disposed between the vaporizer 10 and the heater 20. As the equalizing pipe 32 is connected to the storage tank 50, the inside of the storage tank 50 and the inside of the equalizing pipe 32 are formed at the same pressure.

The second pressure control unit C2 senses the pressure in the storage tank 50 or the pressure equalizing pipe 32 and opens the valve 34 disposed in the pressure equalizing pipe 32 based on this.

For example, when the internal pressure of the storage tank 50 is lower than the preset reference pressure range, the second pressure control unit C2 opens the valve 34 to store a portion of the gas supplied from the vaporizer 10. Inflow to (50). And when the internal pressure of the storage tank 50 returns to the reference pressure range, the 2nd pressure control unit C2 will close the valve 34 arrange | positioned at the equalizing piping 32. As shown in FIG.

Here, the reference pressure range refers to a range of pressures in which the liquefied gas of the storage tank 50 can be smoothly supplied to the vaporizer 10 by the pressure inside the storage tank 50.

The pressure adjusting unit 30 configured as described above is provided to maintain the pressure inside the storage tank 50 in the reference pressure range.

In general, when the liquefied gas stored in the storage tank 50 is exhausted, the internal pressure of the storage tank 50 is also lowered, so that the liquefied gas remaining in the storage tank 50 is not smoothly supplied to the vaporizer 10. . In the conventional case, a pump is used to solve this problem.

However, the gas supply module 60 according to the present embodiment maintains the pressure inside the storage tank 50 in the reference pressure range through the pressure adjusting unit 30 without using a pump. Therefore, even without a pump, the liquefied gas can be continuously supplied to the vaporizer 10 regardless of the remaining amount of the liquefied gas.

Meanwhile, in the summer, when the atmospheric temperature is high, the storage tank 50 may be heated so that the internal pressure of the storage tank 50 may be higher than the reference pressure range. In this case, the pressure regulator 30 according to the present embodiment is used as a bypass path.

For example, when the internal pressure of the storage tank 50 is higher than the preset pressure beyond the reference pressure range, the second pressure control unit C2 opens the valve 34 installed in the pressure equalizing pipe 32. Therefore, the gas in the storage tank 50 is directly supplied to the first supply pipe 13 side through the pressure equalizing pipe 32. In addition, since the temperature of the gas is high, the gas is directly supplied to the second supply pipe 23 through the bypass pipe 25 without passing through the heater 20 described above.

And when the internal pressure of the storage tank 50 returns to the reference pressure range, the 2nd pressure control unit C2 will close the valve 34 arrange | positioned at the equalizing piping 32. As shown in FIG.

As such, the pressure adjusting unit 30 according to the present embodiment supplies the gas supplied from the vaporizer 10 to the storage tank 50 through the pressure equalizing pipe 32, or supplies the gas in the storage tank 50 to the gas utilization facility ( 80 is used as a bi-directional passage to feed.

Pneumatic supply unit 40 may be provided with one or a plurality, and compresses the gas contained in the storage tank 50 to supply to the supply tank (90).

To this end, the pneumatic supply unit 40 is a compressor 41 for compressing gas, a conveying pipe 42 for connecting the compressor and the storage tank 50, and a pneumatic pipe for connecting the compressor 41 and the supply tank 90 ( 43).

In the present invention, the supply of the liquefied gas is made through Tank Lorry. That is, the liquefied gas carried by tank lorry is stored in the storage tank 50. Therefore, the supply tank 90 may mean a tank of tank lorry.

As in the storage tank 50 described above, when the liquefied gas stored in the supply tank 90 is reduced by supplying the liquefied gas to the storage tank 50, the internal pressure of the supply tank 90 is lowered, and thus the supply tank ( The liquefied gas remaining in 90 is not smoothly transferred to the storage tank 50. In the conventional case, a pump is used to solve this problem.

However, the gas supply module 60 according to the present embodiment uses the pneumatic supply unit 40 without using a pump to transfer the liquefied gas stored in the supply tank 90 to the storage tank 50.

The pneumatic supply unit 40 receives gas from the storage tank 50 through the transfer pipe 42, and then compresses the gas in the compressor. Then, the compressed gas is supplied to the supply tank 90 through the pneumatic pipe 43.

Accordingly, the inside of the supply tank 90 is constantly maintained at a constant pressure, and the liquefied gas inside the supply tank 90 is continuously transferred to the storage tank 50 by this internal pressure.

The compressor 41, the conveying pipe 42, and the pneumatic pipe 43 may be connected to each other through a 4-way valve. However, it is not limited thereto.

In addition, the pneumatic supply part 40 recovers the gas remaining in the supply tank 90 after supplying all the liquefied gas of the supply tank 90 to the storage tank 50, and supplies it to the storage tank 50. In this case, the flow of gas in the pneumatic supply portion 40 flows in the opposite manner to the case described above.

In addition, the gas supply module 90 according to the present embodiment includes two pipes connected to the supply tank 90. One is the pneumatic pipe 43 described above, and the other is the inlet pipe 51 connecting the supply tank 90 and the storage tank 50.

The inflow pipe 51 is used to transfer the liquefied gas of the supply tank 90 to the storage tank 50.

In addition, the gas supply module 60 according to the present embodiment includes a liquid supply pipe 12 branched from the inlet pipe 51. Based on the point where the liquid supply pipe 12 is connected, the inlet pipe 51 is the first inlet pipe 51a connected to the supply tank 90 and the second inlet pipe 51b connected to the storage tank 50. ) Can be separated.

The liquid supply pipe 12 is a pipe for supplying liquefied petroleum to the vaporizer 10, one end of which is connected to the inflow pipe 51, and the other end of which is connected to the vaporizer 10. Accordingly, the liquefied gas stored in the storage tank 50 is supplied to the vaporizer 10 through the second inflow pipe 51b and the liquid supply pipe 12.

In addition, the gas supply module 60 according to the present embodiment may directly supply the liquefied gas from the supply tank 90 to the vaporizer 10 using the first inlet pipe 51a and the liquid supply pipe 12. Accordingly, even when the storage tank 50 is not available, such as repairing the storage tank 50 or performing an open inspection of the storage tank 50, the gas is supplied to the gas utilization facility 80 by utilizing the supply tank 90. Can be supplied continuously.

The check valve 52 may be installed on the first inflow pipe 51a to prevent backflow of the liquefied gas. In addition, the gas supply module 60 according to the present embodiment may further include a plurality of valves installed on pipes as necessary in addition to the above-described valves. Also, although not shown, a watering pipe may be provided in the gas supply module 60.

In the gas supply facility according to the present embodiment described above, all the components and pipes except the supply tank 90 and the storage tank 50 are combined on a frame and constitute one gas supply module 60.

Therefore, since the installation of the gas supply facility is completed only by carrying only the gas supply module 60 and connecting the pre-installed storage tank 50 and the gas supply module 60, installation of the facility is very easy. To this end, the gas supply module 60 is sized to be transported through the road in a state in which the vaporizer 10, the pneumatic supply 40, the heater 20, and the pressure regulator 30 are coupled to the frame 5. Is formed.

In addition, the gas supply module 60 includes a pressure equalizing pipe 35 connected to a storage tank, a transfer pipe 42, a second inflow pipe 51b, a pneumatic pipe 43 connected to a supply tank, and a first inflow pipe 51a. ), And a connecting flange (F) is installed in the first supply pipe (23) connected to the gas utilization facility (80).

Therefore, the gas supply module 60 may be connected to the external pipes through the connection flange (F).

Next, the overall operation of the gas supply facility according to the embodiment of the present invention will be described.

The liquefied gas stored in the storage tank 50 is supplied to the vaporizer 10 through the second inlet pipe 51b and the liquid supply pipe 12 and temporarily stored in the storage space 15 provided in the vaporizer 10. .

The vaporizer 10 converts the liquefied gas into gas by applying heat to the liquefied gas stored in the storage space 15 through the heating device 11.

The gas phase-converted in the vaporizer 10 moves to the heater 20 through the first supply pipe 13. After the heater 20 is heated, the gas is maintained and supplied to the gas utilization facility 80 through the second supply pipe 23.

As described above, when the atmospheric temperature is high, such as summer, the gas does not move to the heater 20 but moves to the second supply pipe 23 through the bypass pipe 25. The selection of the heater 20 and the bypass pipe 25 can be made via an automatic valve 27 or a manual valve 27.

In order to maintain a constant pressure of the gas supplied to the gas utilization facility 80 in the above process, the first pressure control unit C1 continuously measures the pressure of the second supply pipe 23. And the temperature of the heating apparatus 11 provided in the vaporizer | carburetor 10 is adjusted according to a change of pressure.

On the other hand, some of the gas phase-converted in the vaporizer 10 is introduced into the storage tank 50 through the pressure equalizing pipe (32). Through this, the pressure in the storage tank 50 is always maintained in the reference pressure range.

When the pressure in the storage tank 50 is within the range of the reference pressure, the second pressure control unit C2 shuts off the valve 34 of the pressure equalizing pipe 32, so that the gas phase-converted in the vaporizer 10 All of them are supplied to the outside via the second supply pipe 23.

In addition, when the outside temperature is high and the pressure inside the storage tank 50 becomes higher than the preset pressure, the second pressure control unit C2 opens the valve 34 installed in the pressure equalizing pipe 32 to open the inside of the storage tank 50. The gas is supplied to the first supply pipe 13 side. In this case, the pressure equalizing pipe 32 functions as a bypass path which sends the gas of the storage tank 50 directly to the 1st supply pipe 13.

When the liquefied gas stored in the storage tank 50 is exhausted, the liquefied gas may be filled in the storage tank 50 through a supply tank 90 such as a tank lorry. In this case, the inflow pipe 51 and the pneumatic pipe 43 are connected to the supply tank 90.

The pneumatic supply unit 40 compresses the gas inside the storage tank 50, and then supplies the compressed gas into the supply tank 90 through the pneumatic pipe 43. Accordingly, the liquefied gas of the supply tank 90 is transferred to the storage tank 50 through the inflow pipe 51 by the internal pressure of the supply tank 90.

Meanwhile, when a problem occurs in the storage tank 50 or when the storage tank 50 is not used due to repair or maintenance, the liquefied gas may be directly supplied from the supply tank 90 to the vaporizer 10. In this case, the liquefied gas is supplied from the supply tank 90 to the vaporizer 10 through the first inlet pipe 51a and the liquid supply pipe 12.

The gas supply facility according to the present embodiment configured as described above is manufactured in a standardized form of the gas supply module. Therefore, the gas supply module can be easily transported and installed in a narrow space.

In addition, since the installation of the gas supply facility is completed only by carrying only the gas supply module and connecting the pre-installed storage tank and the gas supply module, installation of the facility is very easy.

In addition, since the gas supply module according to the present embodiment has a pneumatic supply part, it is possible to quickly and easily transfer the liquefied gas of the supply tank to the storage tank, whereby the tank lorry does not need to be equipped with additional equipment such as a pump.

In addition, the gas inside the storage vessel can be directly supplied to the gas utilization facility without passing through the vaporizer through the pressure equalizing pipe, thereby minimizing the operation of the vaporizer, thereby minimizing the energy required to supply the gas.

Meanwhile, the present invention is not limited to the above-described embodiment, and various modifications are possible.

3 and 4, in the gas supply facility according to the present embodiment, the components constituting the gas supply module 60 are accommodated in the case 7.

The case 7 has an internal space for accommodating components such as the vaporizer 10, the pressure regulator 30, and the pneumatic supply 40. The interior space can be partitioned into multiple zones for easy storage of the components. In this case, each zone may be divided into partition walls, but is not limited thereto.

The case 7 may include at least one door (not shown), and when the liquefied gas leaks, the wall or door may be discharged to the outside of the case 7 by the natural convection phenomenon. At least one exhaust hole 6 may be provided in the.

The exhaust hole 6 may be disposed on all four sides of the case 7. In addition, since the specific gravity of the liquefied gas is larger than the specific gravity of the air, in view of this, the exhaust hole 6 may be disposed below the wall.

Another gas supply module 60 in the present embodiment is configured to be transported to the vehicle. Therefore, the case 7 is formed in a size and volume that can be transported through a general road. For example, the case 7 may be formed of a standard metal box such as a container. However, the configuration of the present invention is not limited thereto.

In addition, the vaporizer 10 according to the present embodiment includes a coil-shaped pipe and the fruit (11a, 熱媒; for example, hot water) for transferring heat to the pipe. The liquefied gas receives heat from the fruit 11a while passing through the coil-shaped pipe, thereby continuously receiving heat even in a gasified state.

Accordingly, the gas discharged from the vaporizer 10 has a higher temperature than the gas discharged from the vaporizer (10 of FIG. 2) of the above-described embodiment.

Therefore, when using the vaporizer 10 according to the present embodiment, the heater (20 in FIG. 2) of the above-described embodiment can be omitted. However, the present invention is not limited thereto, and a heater may be included if necessary.

On the other hand, by omitting the heater, the gas supply module 60 according to the present embodiment does not have a bypass pipe (25 in FIG. 2).

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and changes can be made without departing from the technical spirit of the present invention described in the claims. It will be obvious to those of ordinary skill in the field.
