Description

Technical Field

[0001] This invention relates to the field of gas safety, and more particularly to a gas safety storage and transportation system and method. Background Technology

[0002] In nuclear power plants, the Hydrogen Distribution System (SGH) supplies hydrogen to the hydrogen-oxygen recombiner of the Exhaust Gas Treatment System (TEG) and to the Chemical and Volume Control System (RCV) to suppress the hydrogenation and decomposition of the primary coolant. To avoid hydrogen leakage and its associated risks from the nuclear island, the hydrogen supply pipelines from the hydrogen storage room to the RCV and TEG users are double-walled. The inner pipeline carries hydrogen, and the outer pipeline carries nitrogen. The double-walled pipeline is equipped with a high-pressure alarm. When hydrogen pressure leaks from the inner pipeline, causing an increase in pressure in the outer pipeline, a DCS alarm is triggered, the gas supply is cut off, and the pipeline is inspected and repaired.

[0003] The double-layered pipe design reduces the risk of hydrogen leakage and also minimizes the risk of damage to the hydrogen transport pipeline caused by projectiles or impacts from heavy objects. However, the section of pipe connecting to the hydrogen storage tank remains unprotected and still carries a risk of leakage. Furthermore, it has significant shortcomings in preventing internal explosions. If an internal gas explosion occurs, the explosion will propagate downstream, potentially causing severe damage to downstream users and impacting the safe operation of the interface system.

[0004] Therefore, this invention provides a storage and transportation solution that integrates combustible gas leakage protection, combustible gas / inert gas transport monitoring, and explosion propagation prevention for industrial scenarios involving the use of hydrogen and nitrogen.

[0028] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the invention will now be described in detail with reference to the accompanying drawings. Features specified with "first," "second," "third," etc., may explicitly or implicitly include one or more of those features. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0029] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0030] like Figure 1 As shown, in one embodiment, a gas safety storage and transportation system of the present invention includes: a gas storage end, a gas transportation pipeline, a gas receiving end, and a monitoring module; the gas storage end transports gas to the gas receiving end through the gas transportation pipeline.

[0031] The gas storage end includes a double-layered storage tank, a first combustible gas pipe 301, and a first inert gas pipe 302; the double-layered storage tank includes a combustible gas tank 101 for storing combustible gas and an inert gas tank 102 for storing inert gas, the combustible gas tank 101 is disposed inside the inert gas tank 102, and the combustible gas tank 101 is surrounded by inert gas inside the inert gas tank 102.

[0032] The gas transport pipeline includes a double-walled system, which consists of an inner pipe 303 and an outer pipe 304 that wraps around the inner pipe 303. The inner pipe 303 is connected to the combustible gas tank 101 via a first combustible gas pipe 301, and the outer pipe 304 is connected to the inert gas tank 102 via a first inert gas pipe 302. A first valve 201 is installed on the first combustible gas pipe 301, and a second valve 202 is installed on the first inert gas pipe 302.

[0033] The monitoring module is used to monitor combustible gas data and / or inert gas data, and is communicatively connected to the first valve 201 and the second valve 202 respectively. It is used to control the opening and closing of the first valve 201 and / or the second valve 202 based on the combustible gas data and / or inert gas data.

[0034] The technical solution implemented in this embodiment involves a double-layered storage tank at the gas storage end and a double-layered transport pipeline at the gas transport end. The outer layer is filled with inert gas, and the inner layer is filled with combustible gas. A monitoring module is installed to monitor whether the combustible gas leaks or explodes, and to adjust the entire gas safety storage and transport system in a timely manner. This system has the following advantages: the double-layered tank design prevents combustible gas from leaking outwards, and the inertization of the inert gas also ensures the safety of combustible gas storage; in the event of an internal explosion in the combustible gas pipeline, the valve can be closed in time to reduce the explosion range and damage.

[0035] Furthermore, such as Figure 2 As shown, in another embodiment, the gas safety storage and transportation system of the present invention further includes: a second combustible gas pipe 305, the input end of the second combustible gas pipe 305 being connected to the inner pipe 303, with a third valve 203 provided at the connection point; the output end of the second combustible gas pipe 305 being connected to the first user, with a seventh valve 207 provided at the connection point; a flame sensor 500 is also provided on the second combustible gas pipe 305, the flame sensor 500 being communicatively connected to a monitoring module, used to monitor whether a flame exists in the second combustible gas pipe 305, and to transmit the monitored flame information to the monitoring module. It also includes: a second inert gas pipe 306, the input end of the second inert gas pipe 306 being connected to the outer pipe 304, with a fourth valve 204 provided at the connection point; the output end of the second inert gas pipe 306 being connected to the second user, with an eighth valve 208 provided at the connection point; and / or, the output end of the second inert gas pipe 306 being connected to air, with a sixth valve 206 provided at the connection point.

[0036] The second combustible gas pipe 305 is connected to the second inert gas pipe 306, and a fifth valve 205 is installed at the connection point to control whether the gases in the second combustible gas pipe 305 and the second inert gas pipe 306 are mixed. When a combustible gas leak occurs and maintenance is required, the combustible gas in the second combustible gas pipe 305 can be mixed with the inert gas in the second inert gas pipe 306 to reduce the concentration of the combustible gas and reduce the risk of explosion.

[0037] The first combustible gas pipe 301 is equipped with a first flame arrester 401, and the second combustible gas pipe 305 is equipped with a second flame arrester 402, which are used to prevent the flame from spreading to the combustible gas tank 101 and the first user. When selecting a flame arrester, it is necessary to customize a suitable flame arrester according to the specific application requirements and gas characteristics to ensure that it can effectively provide the required safety protection.

[0038] In an optional embodiment, pressure gauges are installed in the combustible gas tank 101, the inert gas tank 102, the inner pipe 303, and the outer pipe 304 to monitor the gas pressure within these tanks. Specifically, a first pressure gauge 601 is installed in the combustible gas tank 101, a second pressure gauge 602 is installed in the inert gas tank 102, a third pressure gauge 603 is installed in the inner pipe 303, and a fourth pressure gauge 604 is installed in the outer pipe 304. A first flow meter 701 is also installed in the inner pipe 303, and a second flow meter 702 is also installed in the outer pipe 304 to monitor whether the transport flow rate of the combustible gas and inert gas reaches the flow rate required by the user. Furthermore, when the second user does not require inert gas, the second flow meter 702 may not be installed in the outer pipe 304, and the inert gas is only used as a protective gas, and the eighth valve 208 can be closed.

[0039] In an optional embodiment, an inert gas tank 102 is equipped with a gas analyzer 800 to monitor whether there is any flammable gas leaking from the flammable gas tank 101 within the inert gas tank 102. In this embodiment, the gas analyzer 800 is used to monitor the gas composition within the inert gas tank in real time. It can detect whether there is a flammable gas leak or whether the concentration of the inert gas is below a safe level. If the concentration of the flammable gas exceeds a preset safety threshold, the detection module can trigger an alarm or automatically take safety measures, such as shutting off the gas supply or activating a fire extinguishing system.

[0040] In an optional embodiment, a gas safety storage and transportation system of the present invention further includes: a gas circulation system, one end of which is connected to an inert gas tank 102, with a ninth valve 209 provided at the connection point, and the other end of which is connected to a second inert gas pipe 306 and an outer pipe 304, with a tenth valve 210 provided at the connection point, for diluting the combustible gas when a leak occurs in the inner pipe 303.

[0041] During transportation, if the flow rate of the first flow meter 701 remains unchanged while the flow rate of the second flow meter 702 decreases, the alarm will sound. At the same time, the first valve 201, the seventh valve 207, and the eighth valve 208 will be closed, indicating that the outer pipe 304 is leaking and needs to be repaired.

[0042] If the flow rate of the first flow meter 701 decreases and the flow rate of the second flow meter 702 increases, the alarm will sound. At the same time, the first valve 201, the seventh valve 207, and the eighth valve 208 will be closed. If the pressure difference between the combustible gas and the inert gas in the inner and outer pipes is not large, the fifth valve 205 can be opened to allow the combustible gas and the inert gas to mix. Then, the sixth valve 206 can be opened to discharge the mixture of combustible gas and inert gas. If the pressure difference between the combustible gas and the inert gas in the inner and outer pipes is large (high combustible gas content), the fifth valve 205 can be opened to allow the combustible gas to enter the outer pipe and mix with the inert gas. Then, the ninth valve 209 and the tenth valve 210 can be opened, and the fan and gas circulation pump in the gas circulation system can be turned on to allow the combustible gas to circulate in the outer pipe for a period of time. Then, all the gas is discharged from the sixth valve 206 to dilute the combustible gas to the greatest extent, thereby ensuring operational safety.

[0043] In this embodiment, the monitoring module is connected to the first valve 201, the second valve 202, the third valve 203, the fourth valve 204, the fifth valve 205, the sixth valve 206, the seventh valve 207, the eighth valve 208, the ninth valve 209, the tenth valve 210, the flame sensor 500, the first pressure gauge 601, the second pressure gauge 602, the third pressure gauge 603, the fourth pressure gauge 604, the first flow meter 701, the second flow meter 702, and the gas analyzer 800. It is used to receive monitoring data from flame sensor 500, first pressure gauge 601, second pressure gauge 602, third pressure gauge 603, fourth pressure gauge 604, first flow meter 701, second flow meter 702, and gas analyzer 800, and to control the opening and closing of first valve 201, second valve 202, third valve 203, fourth valve 204, fifth valve 205, sixth valve 206, seventh valve 207, eighth valve 208, ninth valve 209, and tenth valve 210.

[0044] The technical solution implemented in this embodiment can monitor the sealing of storage tanks and pipelines to prevent gas leaks and ensure the safety of combustible gas transportation. During the transportation of combustible and inert gases to users, it can safely supply a predetermined flow rate of combustible and inert gases according to user needs. In the event of a leak in the combustible gas transportation pipeline, the gas circulation system dilutes the combustible gas to the maximum extent, reducing the danger and destructiveness. In the event of an internal explosion in the combustible gas pipeline, the explosion range and destructiveness can be effectively reduced by installing flame arresters and closing valves.

[0045] like Figure 3 As shown, in an optional embodiment, the present invention also provides a gas safe storage and transportation method, applied to the above-mentioned gas safe storage and transportation system, comprising:

[0046] S1. Receive monitoring data from the flame sensor and determine whether a flame signal has been generated;

[0047] S2. If so, close the third, seventh, and eighth valves, and open the fifth valve.

[0048] Specifically, during the explosion of combustible gas, an explosive flame is generated. When the flame sensor 500 detects the flame signal, the alarm sounds, and the controller immediately closes the third valve 203 and the seventh valve 207. At this time, the third valve 203, the seventh valve 207, the first flame arrester 401, and the second flame arrester 402 ensure that the explosion will not spread to the upstream combustible gas tank 101 or the downstream first user. In addition, closing the eighth valve 208 and opening the fifth valve 205 allows the inert gas in the outer pipe 304 to further suppress the combustible gas explosion.

[0049] In this embodiment, it also includes: S3, receiving monitoring data from the pressure gauge and determining whether the combustible gas tank, inert gas tank, inner pipe, and outer pipe are airtight.

[0050] Specifically, this includes: filling the double-layered storage tank with gas (high-pressure for combustible gas, low-pressure for inert gas): Initially, all valves are closed, all instruments and equipment are powered on, providing real-time feedback and ready for immediate use. First, connect the inert gas tank to an external inert gas source. By monitoring the pressure of the second pressure gauge 602, fill the inert gas tank with inert gas at a predetermined pressure. Monitor the second pressure gauge 602. If the pressure stabilizes after a period of time, the inert gas tank's airtightness is considered satisfactory. If the pressure continues to drop, the inert gas tank's airtightness needs to be checked. If the pressure of the first pressure gauge 601 increases, the alarm will sound, indicating insufficient sealing of the combustible gas tank, causing inert gas to enter. This alerts personnel to promptly release the inert gas and check the combustible gas tank's airtightness. If no problems are found during the filling process of the inert gas tank, high-pressure combustible gas is then added to the combustible gas tank. The pressure is monitored by the first pressure gauge 601. Combustible gas at a predetermined pressure is added to the combustible gas tank, and the pressure is monitored again. If the pressure stabilizes after a period of time, the airtightness of the combustible gas tank is considered to meet the requirements, and the filling of the double-layered storage tank is complete. If the pressure continues to drop, it indicates a leak in the combustible gas tank under high pressure. The combustible gas needs to be discharged promptly, and the leak point of the combustible gas tank needs to be checked. During this process, the outer inert gas tank provides insulation, preventing the combustible gas from being directly released into the environment. Furthermore, the dilution and inerting of the inert gas ensures that the combustible gas will not reach its explosive limit and cause an explosion. During the filling process, the gas analyzer monitors the gas composition inside the inert gas tank in real time. Once combustible gas components are detected, the alarm will sound, reminding personnel to promptly check the airtightness of the combustible gas tank.

[0051] Pipeline airtightness test: Initially, the second pressure gauge 602 and the first pressure gauge 601 are stable, all valves are closed, all instruments and equipment are powered on, and can provide real-time feedback and are ready for use at any time. Adjust the second valve 202 to fill the outer pipe 304 of the double-tube system with inert gas at an appropriate pressure, then close the second valve 202. If the fourth pressure gauge 604 shows a stable reading, it indicates that the airtightness of the outer pipe 304 connection meets the filling requirements. If the reading of the fourth pressure gauge 604 drops, the alarm will sound, and the operator needs to release the inert gas through the sixth valve 206 and test the outer pipe 304. If the reading of the third pressure gauge 603 rises during the inert gas filling process, the alarm will sound, and the operator needs to release the inert gas through the sixth valve 206 and the fifth valve 205, indicating that there is a crack in the inner pipe 303, which needs to be tested. Once the airtightness of the outer pipe 304 meets the requirements, adjust the first valve 201. At this time, a certain pressure of combustible gas is injected into the inner pipe 303. Close the first valve 201. If the readings of the third pressure gauge 603 and the fourth pressure gauge 604 remain unchanged, it indicates that the airtightness of the inner pipe 303 meets the gas filling requirements. If the reading of the third pressure gauge 603 decreases and the reading of the fourth pressure gauge 604 increases, the alarm will sound, indicating that there is a leak in the inner pipe 303 and the hydrogen flame arrester pipeline. The staff will open the fifth valve 205 to discharge the combustible gas into the outer pipe 304 pipeline, where it will mix with the inert gas, thereby safely discharging the combustible gas from the inner pipe 303. Subsequently, the inner pipe 303 pipeline will be inspected.

[0052] The technical solution implemented in this embodiment can detect the airtightness of the double-layered storage tank and double-pipe system during gas filling, and promptly shut off the transmission path of the explosion in the event of a combustible gas explosion, preventing the explosion from propagating upstream or downstream. Furthermore, the inert gas inside the outer pipe can further suppress combustible gas explosions.

[0053] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
