Description

Technical Field

[0001] This invention relates to the field of hazardous chemical monitoring technology, and more specifically to a monitoring system based on real-time monitoring and analysis of hazardous chemical safety. Background Technology

[0002] Hazardous chemicals include liquid carbon dioxide. During transportation or storage, liquid carbon dioxide is stored in storage tanks, and the storage tanks are not filled to the brim with liquid carbon dioxide. Generally, the storage tanks are filled to less than 95% of their capacity, leaving a space at the top of the storage tanks. The gas in the reserved space is carbon dioxide gas.

[0003] When a ship is in transit, the carbon dioxide liquid will slosh around in the storage tank due to the ship's acceleration, deceleration or turning. This will cause some of the carbon dioxide gas in the reserved space to be pressurized. This pressure will be transmitted to the inner wall of the storage tank. If the pressure is too high, it may cause the storage tank to crack or even explode, creating a safety hazard. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a monitoring system based on real-time monitoring and analysis of hazardous chemical safety, which can be used to improve the safety of storage tanks during transportation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a monitoring system based on real-time monitoring and analysis of hazardous chemical safety, comprising a storage tank, wherein the storage tank includes a reserved space located above the liquid hazardous chemical;

[0006] A data acquisition layer, comprising multiple sensors, acquires at least pressure data within the reserved space;

[0007] A data processing layer, comprising a data processing unit, wherein the data processing unit divides the reserved space into a first pressure zone and a second pressure zone under a first definition;

[0008] The data processing unit divides the reserved space into a third pressure zone and a fourth pressure zone under the second definition.

[0009] Gas valves are connected to the first pressure zone, the second pressure zone, the third pressure zone, and the fourth pressure zone;

[0010] In response to the driver's driving operation, the data processing unit selects the first definition and / or the second definition;

[0011] The two storage tanks are provided with a first buffer area and a second buffer area. The gas valves on the first pressure area and the third pressure area of ​​the first storage tank are connected to the first buffer area, and the gas valves on the second pressure area and the fourth pressure area are connected to the second buffer area. The gas valves on the first pressure area and the third pressure area of ​​the second storage tank are connected to the second buffer area, and the gas valves on the second pressure area and the fourth pressure area are connected to the first buffer area.

[0012] The first buffer area is connected to the second buffer area and is equipped with a first valve;

[0013] The data processing unit detects whether the pressure data of each pressure zone selected below is greater than a first threshold or less than a second threshold.

[0014] If the pressure data in the first pressure zone under the same definition is greater than the first threshold, and the pressure data in the second pressure zone is greater than the second threshold, then the control layer continuously opens the gas valve on the first pressure zone for a first unit time, and after a delay of one unit time, continuously opens the gas valve on the second pressure zone for a second unit time.

[0015] If the pressure data in the first pressure zone under the same definition is greater than the first threshold, and the pressure data in the second pressure zone is less than the second threshold, then the control layer continuously opens the gas valve in the first pressure zone for a first unit time, and simultaneously continuously opens the gas valve in the second pressure zone for a second unit time.

[0016] The second unit of time is greater than the first unit of time;

[0017] If the pressure difference between the two reserved spaces is greater than the pressure threshold, the first valve connects the first buffer area and the second buffer area.

[0018] As a further improvement of the present invention, when the first valve connects the first buffer area and the second buffer area, one of the gas valves on the storage tank is opened.

[0019] As a further improvement of the present invention, the first definition includes acceleration operation and deceleration operation. The data processing unit obtains instantaneous speed change within a speed adjustment unit time. The instantaneous speed change represents the acceleration within the speed adjustment unit time. The speed adjustment unit time is less than the first unit time. If the instantaneous speed change is greater than the acceleration threshold, the control layer controls the output power of the ship engine to be within the limit.

[0020] As a further improvement of the present invention, the second definition includes left turn operation and right turn operation. The data processing unit obtains the instantaneous turning angle in the turning unit time. The instantaneous turning angle represents the bow turning angle in the turning unit time. The turning unit time is greater than the speed regulation unit time. If the instantaneous turning angle is greater than the turning angle threshold, the control layer adjusts the transmission ratio between the rudder blade and the rudder handle on the stern rudder.

[0021] As a further improvement of the present invention, the first buffer area includes a first exchange area and a first connecting area, and the second buffer area includes a second exchange area and a second connecting area. Both the first exchange area and the second exchange area are pre-stored with carbon dioxide gas. The pressure of the carbon dioxide gas is lower than the pressure in the corresponding first connecting area or the second connecting area. A connecting valve is provided between the first exchange area and the first connecting area, and between the second exchange area and the second connecting area. The first valve is located between the first connecting area and the second connecting area.

[0022] As a further improvement of the present invention, a first partition and a second partition are provided between the first exchange area and the first connecting area, and between the second exchange area and the second connecting area. A voltage stabilizing area is formed between the first partition and the second partition. The first partition is fixedly connected to the first buffer area, and the second partition is slidably connected to the first buffer area. A compression spring is provided in the voltage stabilizing area.

[0023] As a further improvement of the present invention, a connecting pipe is fixedly connected to the first partition, the end of the connecting pipe away from the first partition passes through the second partition, the connecting valve is disposed on the connecting pipe, the opening of the connecting pipe near the first partition is constricted, and the opening of the connecting pipe away from the first partition is open.

[0024] As a further improvement of the present invention, the first exchange area and the second exchange area are respectively connected to the corresponding reserved space and are provided with a second valve.

[0025] As a further improvement of the present invention, under the combined effect of the first definition and the second definition, the reserved space includes a first overlapping area and a second overlapping area. The range of the first overlapping area is smaller than the range of the second overlapping area. The control layer simultaneously and continuously opens the two gas valves adjacent to the first overlapping area at a third unit time, and after a delay of one unit time, continuously opens the two gas valves adjacent to the second overlapping area at a third unit time.

[0026] As a further improvement of the present invention, it is determined whether the ratio of the first overlapping area to the second overlapping area is greater than a ratio threshold.

[0027] The beneficial effects of this invention are as follows: In this invention, the carbon dioxide gas pressure in the storage tank is adjusted according to the driver's driving operation. Under a first definition, when the pressure data in the first pressure zone exceeds a first threshold, the gas valve on the first pressure zone will open for a first unit time, causing the carbon dioxide gas at that location to be released. The amount of released carbon dioxide gas is minute. This is to provide instantaneous pressure relief, prevent excessive instantaneous pressure on the inner wall of the first pressure zone, and balance the carbon dioxide gas pressure between the two storage tanks. Because after the gas valve on the first pressure zone in the first storage tank opens, the carbon dioxide gas enters the first buffer zone; after the gas valve on the first pressure zone in the second storage tank opens, the carbon dioxide gas enters the second buffer zone. Furthermore, after the gas valve on the second pressure zone in the first storage tank opens, the carbon dioxide gas in the second buffer zone balances the carbon dioxide gas pressure in the reserved space of the first storage tank. Similarly, after the gas valve on the low-pressure zone in the second storage tank opens, the carbon dioxide gas in the first buffer zone balances the carbon dioxide gas pressure in the reserved space of the second storage tank.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0032] Reference Figure 1 and Figure 2 As shown, this embodiment of a monitoring system based on real-time monitoring and analysis of hazardous chemical safety includes a storage tank, which includes a reserved space above the liquid hazardous chemical. The reserved space is set according to the capacity of the storage tank. Because the liquid hazardous chemical may vaporize, such as liquid carbon dioxide, the storage tank is under pressure. When the pressure in the storage tank is too high, there may be situations such as the storage tank exploding.

[0033] The data acquisition layer includes multiple sensors that collect pressure data, including at least the pressure data within the reserved space. There are at least four sensors located in the first pressure zone 1, second pressure zone 2, third pressure zone 3, and fourth pressure zone 4, respectively, and they acquire the pressure of the corresponding pressure zone. In a stable state, the pressure data acquired by the four sensors are theoretically consistent (excluding errors). When liquid carbon dioxide sloshes inside the storage tank, the instantaneous gas-carrying space in the first pressure zone 1, second pressure zone 2, third pressure zone 3, and fourth pressure zone 4 changes depending on the direction of sloshing. This causes the carbon dioxide gas at that location to be compressed or expanded. In the compressed state, the carbon dioxide gas pressure at that location changes, i.e., increases, which increases the pressure on the inner wall of the corresponding pressure zone.

[0034] A data processing layer, comprising a data processing unit, wherein the data processing unit divides the reserved space into a first pressure zone 1 and a second pressure zone 2 under a first definition;

[0035] The data processing unit divides the reserved space into a third pressure zone 3 and a fourth pressure zone 4 under the second definition; a rectangular coordinate system is established with the center of the storage tank top view, the first pressure zone 1 and the second pressure zone 2 are the upper and lower half zones; the third pressure zone 3 and the fourth pressure zone 4 are the left and right half zones;

[0036] Gas valves are connected to the first pressure zone 1, the second pressure zone 2, the third pressure zone 3, and the fourth pressure zone 4.

[0037] In response to the driver's driving operation, the data processing unit selects the first definition and / or the second definition;

[0038] The two storage tanks are provided with a first buffer zone and a second buffer zone. The gas valves on the first pressure zone 1 and the third pressure zone 3 of the first storage tank are connected to the first buffer zone, and the gas valves on the second pressure zone 2 and the fourth pressure zone 4 are connected to the second buffer zone. In the second storage tank, the gas valves on the first pressure zone 1 and the third pressure zone 3 are connected to the second buffer zone, and the gas valves on the second pressure zone 2 and the fourth pressure zone 4 are connected to the first buffer zone.

[0039] The first buffer area is connected to the second buffer area and is equipped with a first valve;

[0040] The data processing unit detects whether the pressure data of each pressure zone selected below is greater than a first threshold or less than a second threshold.

[0041] The control layer and the data processing layer are both processors. If the pressure data in the first pressure zone under the same definition is greater than the first threshold, the first threshold is less than the maximum pressure that the storage tank can withstand, and the pressure data in the second pressure zone is greater than the second threshold, then the control layer continuously opens the gas valve on the first pressure zone for a first unit time, and after a delay of one unit time, continuously opens the gas valve on the second pressure zone for a second unit time.

[0042] If, under the first definition, the pressure data in the first pressure zone 1 exceeds the first threshold, the gas valve on the first pressure zone 1 will open for a first unit time, causing carbon dioxide gas at that location to be released. The amount of carbon dioxide gas released is minute. The first unit time ranges from 0.2 to 1 second, and is generally between 0.4 and 0.5 seconds, in order to release pressure instantaneously and prevent the instantaneous pressure on the inner wall of the first pressure zone 1 from being too high.

[0043] The delay period needs to respond to the driver's driving operation. In the absence of acceleration, deceleration, or turning, the delay period is activated and lasts for at least 5 seconds to ensure that the driver can perform driving operation again. Then, the gas valve on the second pressure zone 2 corresponding to the first pressure zone 1 is opened. After the gas valve on the first pressure zone 1 in the first storage tank is opened, carbon dioxide gas enters the first buffer zone. After the gas valve on the first pressure zone 1 in the second storage tank is opened, carbon dioxide gas enters the second buffer zone. After the gas valve on the second pressure zone 2 in the first storage tank is opened, the carbon dioxide gas in the second buffer zone will balance the carbon dioxide gas pressure in the reserved space of the first storage tank. After the gas valve on the low pressure zone of the second storage tank is opened, the carbon dioxide gas in the first buffer zone will balance the carbon dioxide gas pressure in the reserved space of the second storage tank.

[0044] The carbon dioxide gas in the two storage tanks can flow into each other, thereby balancing the carbon dioxide gas pressure in the two storage tanks and preventing the carbon dioxide gas pressure in one storage tank from being too high and the carbon dioxide gas pressure in the other storage tank from being too low.

[0045] If the pressure data in the first pressure zone under the same definition is greater than the first threshold, and the pressure data in the second pressure zone is less than the second threshold, then the control layer continuously opens the gas valve in the first pressure zone for a first unit time, and simultaneously continuously opens the gas valve in the second pressure zone for a second unit time.

[0046] Compared with the above, the difference is whether the pressure data in the second pressure zone 2 is less than the second threshold. The difference between the second threshold and the first threshold is set to be between 0.2% and 0.5%. The gas valve on the second pressure zone 2 is opened in time, so that carbon dioxide gas enters the corresponding reserved space from the first buffer zone or the second buffer zone to make up for the reduced pressure. This reduces the amount and speed of high-pressure carbon dioxide gas moving from the first pressure zone 1 to the second pressure zone 2, thereby smoothing the degree of sloshing of liquid carbon dioxide gas.

[0047] The second unit time is greater than the first unit time to ensure pressure balance;

[0048] If the pressure difference between the two reserved spaces is greater than the pressure threshold, the first valve connects the first buffer area and the second buffer area to balance the pressure difference between the two first buffer areas and the second buffer area. The pressure threshold is set in the range of 0.8% to 0.10%.

[0049] The sensors also include a temperature sensor to monitor the temperature of the storage tank in real time;

[0050] The control layer uses different temperature data to set different first and second thresholds, etc.

[0051] When the first valve connects the first buffer area and the second buffer area, one of the gas valves on the storage tank opens to balance the gas pressure in the two reserved spaces.

[0052] The first definition includes acceleration and deceleration operations. The data processing unit obtains instantaneous speed changes within a speed adjustment unit time. The instantaneous speed change represents the acceleration within the speed adjustment unit time. The acceleration can be positive or negative, representing acceleration and deceleration. The speed adjustment unit time is less than the first unit time, avoiding sudden acceleration or deceleration by the driver. Reducing the speed adjustment unit time allows for the acquisition of more acceleration data. Each segment of acceleration data is controlled to control the degree of carbon dioxide liquid sloshing and prevent excessive sloshing. If the instantaneous speed change is greater than the acceleration threshold, which is set to be less than half of the ship's fastest acceleration, the control layer controls the output power of the ship's engine within a limit. This limit ensures that the ship's acceleration is equal to or less than half of the limit, preventing excessive sloshing of the carbon dioxide liquid in the storage tank and thus controlling the pressure generated by the sloshing of the carbon dioxide liquid on the inner wall of the storage tank.

[0053] Reference Figure 1As shown, the second definition includes left turn and right turn operations. The data processing unit obtains the instantaneous turning angle within a turning unit time. The instantaneous turning angle represents the bow turning angle within the turning unit time. The turning unit time is greater than the speed adjustment unit time. Since the speed at which the driver turns the rudder is not uniform, the turning unit time is increased to make the obtained instantaneous turning angle more accurate. If the instantaneous turning angle is greater than the turning angle threshold, the control layer adjusts the transmission ratio between the rudder blade and the rudder handle on the stern rudder. The transmission ratio is the turning rotation ratio. This adjustment increases the transmission ratio so that after the driver turns the rudder handle for the same number of turns, the rotation angle of the rudder blade decreases, thereby controlling the bow turning angle of the ship and thus controlling the degree of carbon dioxide liquid sloshing.

[0054] The first buffer area includes a first exchange area and a first connecting area, and the second buffer area includes a second exchange area and a second connecting area. Both the first and second exchange areas are pre-stored with carbon dioxide gas. The pressure of the carbon dioxide gas is lower than the corresponding pressure in the first or second connecting area. Connecting valves are provided between the first and first exchange areas and between the second and second exchange areas. The first valve is located between the first and second connecting areas. The first and second exchange areas are connected to a release device, which releases the carbon dioxide gas. When the carbon dioxide pressure in the first or second connecting area is too high, the corresponding connecting valve is opened, allowing the carbon dioxide gas in the first or second connecting area to flow to the corresponding first and second exchange areas. Furthermore, the pre-stored carbon dioxide gas in the first and second exchange areas prevents contamination by other gases, ensuring safety.

[0055] A first partition and a second partition are provided between the first exchange zone and the first connecting zone, and between the second exchange zone and the second connecting zone. A pressure stabilizing zone is formed between the first partition and the second partition. The first partition is fixedly connected to the first buffer zone, and the second partition is slidably connected to the first buffer zone. A compression spring is provided in the pressure stabilizing zone. The compression spring can provide a buffer, so that when carbon dioxide gas in the first connecting zone flows to the first exchange zone, the second partition will move towards the first partition to a certain extent, and the compression spring will be further compressed to control the flow rate of carbon dioxide gas entering the first exchange zone.

[0056] A connecting pipe is fixedly connected to the first partition. The end of the connecting pipe away from the first partition passes through the second partition. The connecting valve is disposed on the connecting pipe. The opening of the connecting pipe near the first partition is constricted, and the opening of the connecting pipe away from the first partition is open.

[0057] The first exchange zone and the second exchange zone are respectively connected to the corresponding reserved space and are equipped with a second valve. When the carbon dioxide gas pressure in the first flow zone or the second flow zone is greater than the carbon dioxide gas pressure in the corresponding first exchange zone or the second exchange zone, that is, when the carbon dioxide gas in the first flow zone or the second flow zone is not released in time, or when the pressure in the two reserved spaces is not balanced, the pressure in the corresponding reserved space can be released directly by opening the second valve.

[0058] Under the combined effect of the first and second definitions, the reserved space includes a first overlapping area and a second overlapping area. The range of the first overlapping area is smaller than that of the second overlapping area. The control layer simultaneously and continuously opens the two gas valves adjacent to the first overlapping area for a third unit time, so that the gas in the first overlapping area can flow out from the two adjacent gas valves. The two gas valves are opened at the same time, which increases the amount of carbon dioxide gas flowing out at that location. The third unit time is shorter than the first unit time and can be between 0.6 and 0.8 times the first unit time, thereby controlling the gas pressure in the first overlapping area. After a delay of one unit time, the two gas valves adjacent to the second overlapping area are continuously opened for a third unit time to balance the gas pressure. The setting of the delay period prevents all four gas valves from being opened, resulting in an excessive amount of gas flowing out.

[0059] Determine whether the ratio of the first overlapping area to the second overlapping area is greater than the ratio threshold. Depending on the degree of carbon dioxide liquid sloshing, the range and degree of compression of carbon dioxide gas in the reserved space are also different. Therefore, there is a range difference between the first overlapping area and the second overlapping area. If the ratio of the first overlapping area to the second overlapping area is greater than the ratio threshold (the ratio threshold can be 1 to 5), then the delay period is cancelled.

[0060] Furthermore, the time for the third unit is set according to a proportional value. Different proportional values ​​result in different degrees of sloshing of the carbon dioxide liquid, which in turn results in different degrees of instantaneous compression or expansion of the carbon dioxide gas. The greater the degree of sloshing, the longer the time for the third unit. The delay period can also be set according to a proportional value. The greater the degree of sloshing of the carbon dioxide gas, the shorter the delay period.

[0061] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
