[0038] The present invention provides a concentrated sulfuric acid leakage monitoring system 100.

[0039] See also Figures 1 to 3In an embodiment of a concentrated sulfuric acid leakage monitoring system 100 of the present invention, the concentrated sulfuric acid leakage monitoring system 100 includes: a collection box 20, the collection box 20 is arranged at the connection 10 of the pipeline to be monitored, the collection box 20 includes a box body 22 and a cover plate 21, the cover plate 21 is detachably connected to the box body 22, the cover plate 21 and the box body 22 are enclosed to form a accommodating cavity 23, a temperature monitoring device 233 is provided in the accommodating cavity 23, and the temperature monitoring device 233 is used to monitor whether liquid leakage occurs in the pipeline to be monitored; a water supply pipe 30, the water supply pipe 30 is fixedly connected to the collection box 20, and the water supply pipe 30 is used to supply water to the accommodating cavity 23.

[0040] Specifically, the connection 10 in this embodiment is located between two sections of the pipeline to be monitored that transport dangerous liquids. It can be understood that the location where the pipeline to be monitored is most likely to leak is the connection of the pipeline, that is, Figure 1 The collection box 20 in this embodiment is arranged directly below the connection 10. The collection box 20 does not touch the pipeline to be monitored. The collection box 20 can be suspended by wire directly below the connection 10, wherein directly below here means that the connection 10 is directly below the gravity direction. The purpose of this arrangement is to ensure that the liquid leaked from the connection 10 can drip onto the collection box. The collection box 20 consists of a cover plate 21 and a box body 22, wherein the cover plate 21 and the box body 22 are detachably connected, which means that the cover plate 21 can be connected to the box body 22 by buckling and other techniques, and can also be separated from the box body 22 by disassembly. The purpose of this design is to make the cover plate 21 replaceable, such as Figure 2 As shown, when the cover plate 21 is connected to the box body 22, a receiving chamber 23 is formed inside the collection box 20, and a temperature monitoring device 233 (hereinafter referred to as a temperature sensor) is also provided in the receiving chamber 23. The function of the temperature monitoring device 233 is to determine whether there is a dangerous liquid leak at the connection 10 by collecting temperature information in the receiving chamber 23. The concentrated sulfuric acid leakage monitoring system 100 of the present invention also includes a water supply pipe 30, which is fixedly connected to the collection box 20. One end of the water supply pipe 30 can be connected to a water tank or a water pump ( Figure 1 (not shown) is connected to thereby transport water into the accommodating chamber 23.

[0041] Specifically, the concentrated sulfuric acid leakage monitoring system 100 of the present invention is capable of monitoring liquid leakage at the connection 10 in that the cover plate 21 is made of corrosive material, wherein the corrosive material refers to a material that is easily corroded by acid. The dangerous liquid (such as concentrated sulfuric acid) leaking from the connection 10 can enter the accommodating chamber 23 by corroding the cover plate 21, and further mix with the water in the accommodating chamber 23 to generate heat. By monitoring the temperature of the water in the accommodating chamber 23, it is determined whether a dangerous liquid leak occurs at the connection 10.

[0042] The water supply pipe 30 in this embodiment connects all the collection boxes 20 . When the collection boxes 20 are connected, the water supply pipe 30 does not penetrate the collection boxes 20 , because the function of the water supply pipe 30 is to deliver water into the collection boxes 20 .

[0043] In one embodiment of the present invention, the collection box 20 is arranged below the connection 10 in the direction of gravity, and the cover plate 21 is arranged on the surface of the collection box 20 facing the connection 10. The cover plate 21 is made of corrosive material and is used to receive liquid leaked from the connection 10.

[0044] It can be seen that the concentrated sulfuric acid leakage monitoring system 100 in the present invention can realize the principle of leakage of dangerous liquid (hereinafter explained by concentrated sulfuric acid as an example) is that concentrated sulfuric acid generates heat when mixed with water, and by monitoring the generation of heat, it is determined whether a leakage occurs at the connection of the monitored pipeline for transporting concentrated sulfuric acid. According to the monitoring principle, if concentrated sulfuric acid leaks at the connection 10, the leaked concentrated sulfuric acid will drip from the connection 10 onto the cover 21. Because the cover 21 is made of corrosive material, the dripping concentrated sulfuric acid will corrode the cover 21, and then the subsequent dripping concentrated sulfuric acid can enter the accommodating chamber 23, and then mix with the water in the accommodating chamber 23 to generate heat. The temperature monitoring device 233 in the accommodating chamber 23 will monitor the water temperature rise caused by the heat, and then determine that the concentrated sulfuric acid has leaked. Specifically, the advantage of the present invention that the cover plate 21 and the box body 22 are detachably connected is that in addition to making the cover plate 21 replaceable, the cover plate 21 can also be replaced after the cover plate 21 is corroded. The purpose of installing the cover plate 21 is to isolate the water in the accommodating chamber 23 from the outside world, thereby eliminating the influence of the external environment on the temperature of the water in the accommodating chamber 23.

[0045] In one embodiment of the present invention, a heat conducting plate 234 is provided in the accommodating chamber 23, and the heat conducting plate 234 divides the accommodating chamber 23 into an upper accommodating chamber 231 and a lower accommodating chamber 232. The water supply pipe 30 is used to supply water to the upper accommodating chamber 231, wherein the distance between the upper accommodating chamber 231 and the connection point 10 is smaller than the distance between the lower accommodating chamber 232 and the connection point 10.

[0046] In the present invention, a heat conducting plate 234 is provided inside the accommodating chamber 23. The function of the heat conducting plate 234 is not only to separate the accommodating chamber 23 into the upper accommodating chamber 231 and the lower accommodating chamber 232, but also to separate the water to be stored in the accommodating chamber 23 from the temperature monitoring device 233, so that when the present invention selects the temperature monitoring device 233 to be used, it is not only necessary to select a waterproof temperature monitoring device 233, but also an electrical circuit (not shown in the figure) is connected to the temperature monitoring device. It can be seen that the design scheme of the concentrated sulfuric acid leakage monitoring system in the present invention can also be that there is no heat conducting plate 234 in the accommodating chamber 23, water is stored in the entire accommodating chamber 23, the temperature monitoring device 233 is immersed in water, and both the electrical circuit and the temperature monitoring device 233 are waterproof. In the solution of the present invention, the water supply pipe 30 is used to transport water to the upper accommodating chamber 231. It is known that the heat conducting plate 234 divides the accommodating chamber 23 into two small accommodating chambers. The small accommodating chamber 10 closer to the connection point is defined as the upper accommodating chamber 231, and the small accommodating chamber 10 farther from the connection point is defined as the lower accommodating chamber 232. This also conforms to the upper and lower positions in the direction of gravity. The purpose of defining the upper and lower accommodating chambers is to ensure that the leaked dangerous liquid can drip into the upper accommodating chamber 231 and mix with the water in the upper accommodating chamber 231.

[0047] In one embodiment of the present invention, the temperature monitoring device 233 is disposed in the lower accommodating chamber 232 , and the temperature monitoring device 233 is attached to the heat conducting plate 234 , and the temperature monitoring device 233 is used to collect the water temperature in the upper accommodating chamber 231 through the heat conducting plate 234 .

[0048] In the present invention, a heat conducting plate 234 and a temperature monitoring device 233 are provided in the accommodating chamber 23, wherein the heat conducting plate 234 can not only separate the accommodating chamber 23, but also prevent the water in the upper accommodating chamber 231 from flowing into the lower accommodating chamber 232. Specifically, in order to prevent the water in the upper accommodating chamber 231 from flowing into the lower accommodating chamber 232, the portion where the heat conducting plate 234 and the inside of the accommodating chamber 23 are connected is sealed with a waterproof sealant. It is known that the heat conducting plate 234 can also be designed as an integrated unit with the collection box 20, but considering the high production cost required for the integrated design and the characteristics of being difficult to disassemble and replace, the present invention adopts a separate structural design. In one embodiment of the present invention, the contact between the heat conducting plate 234 and the cavity wall of the accommodating chamber 23 is sealed by a waterproof glue. It is known that the purpose of the temperature monitoring device 233 being attached to the heat conducting plate 234 is to enable the temperature monitoring device 233 to obtain the temperature of the water in the upper accommodating chamber through the heat conducting plate 234 at the first time.

[0049] In one embodiment of the present invention, at least two through holes 221 are provided on the box body 22 , and the water supply pipe 30 is adapted to be connected with the through holes 221 , and the water supply pipe 30 delivers water to the accommodating cavity 23 through the through holes 221 .

[0050] Knowable, if Figure 2 In the present invention, the collection box 20 is provided with a through hole 221. Specifically, because the function of the through hole 221 is to allow the water supply pipe 30 to transport water into the upper accommodating chamber 231 through the through hole 221, the through hole 221 is provided on the box body corresponding to the upper accommodating chamber 231. In addition to transporting water into the upper accommodating chamber 231, the through hole 211 is also used to connect two adjacent collection boxes 20 through the water supply pipe 30, such as Figure 2 As shown, each collection box 20 is provided with at least two through holes 221, and the size of the through holes 221 is adapted to the size of the water supply pipe 30. In this embodiment, the adaptation means that the water supply pipe 30 can be fixedly embedded in the through holes 221. In an optimal solution of the present invention, the two through holes 221 on each collection box 20 are arranged on the same horizontal plane, and the depth of the water supply pipe 30 entering the through holes 221 is less than or equal to the thickness of the box body of the collection box 20.

[0051] In one embodiment of the present invention, one of the two through holes is used as a first through hole, one end of the water supply pipe 30 connected to the first through hole is used as a first end portion, the outer surface of the box body 22 including the first through hole is used as a first box surface, the water supply pipe 30 is inserted into the first through hole, and the section tangent to the water supply pipe 30 and the first box surface is used as a first section, and the distance from the first end portion to the first section is less than or equal to the depth of the first through hole.

[0052] like Figure 3 As shown, in the present invention, a through hole 221 is randomly selected on a collection box 20 as the first through hole, for example Figure 2 The through hole 221 in part a, takes the end of the water supply pipe 30 connected to the first through hole connected to the first through hole as the first end portion, takes the outer surface of the box body 22 where the first through hole is located as the first box surface, the water supply pipe 30 connected to the first through hole is inserted into the first through hole, takes the section tangent to the first box surface as the first section, the distance from the first end portion to the first section is the depth of the water supply pipe 30 inserted into the first through hole, and the distance from the first end portion to the first section is less than or equal to the depth of the first through hole, wherein the depth of the first through hole refers to the thickness of the box body 22 at the first through hole, and in the present invention, the thickness of the box body 22 is designed to be uniform.

[0053] In one embodiment of the present invention, at least two blocking devices 24 are disposed in the upper accommodating chamber 231 , and the blocking devices 24 are used to block the water supply pipe 30 from delivering water to the upper accommodating chamber 231 .

[0054] In one embodiment of the present invention, the blocking device 24 is adapted to the size of the water supply pipe 30 .

[0055] In the present invention, at least one barrier device 24 is further provided in the upper accommodating chamber 231. Figure 2 As shown, the function of the blocking device 24 can be explained in combination with the following specific application scenarios. When the concentrated sulfuric acid leakage monitoring system starts to operate, the water supply pipe 30 transports water to the upper accommodating chamber 231. Because all the collection boxes 20 are interconnected through the water supply pipe 30, when the upper accommodating chamber 231 in all the collection boxes 20 is filled with water, according to the principle of communicating vessels, the position of the water will be level with the position of the through hole 221. At this time, the blocking device 24 is lowered to block the end of the water supply pipe 30 that transports water to the upper accommodating chamber. It can be understood that the blocking device 24, the through hole 221 and the water supply pipe 30 are connected to each other. The sizes of the three water pipes 30 are matched, and the number of the blocking devices 24 is equal to the number of the through holes 221. It can be understood that when the blocking device 24 is lowered to block the water supply pipe 30 from supplying water to the upper accommodating chamber 231, the water in the upper accommodating chamber 231 will be isolated from the water outside. In this way, when the leaked dangerous liquid flows into the upper accommodating chamber 231, the isolated upper accommodating chamber 231 prevents the water mixed with the dangerous liquid from flowing into the water supply pipe 30, and the heat generated by the mixing of the dangerous liquid and water is not easy to spread.

[0056] See also Figure 4 The present invention also provides a concentrated sulfuric acid leakage monitoring method. In one embodiment of the concentrated sulfuric acid leakage monitoring method of the present invention, the concentrated sulfuric acid leakage monitoring method comprises the following steps:

[0057] Step S10, obtaining temperature information through the temperature monitoring device, and judging whether the pipeline to be monitored leaks according to the temperature information.

[0058] Step S20: If the pipeline to be monitored leaks, determine the leakage point of the pipeline to be monitored according to the temperature information.

[0059] Step S30, outputting prompt information including the leakage point.

[0060] Water is stored in the upper accommodating chamber 231 in the collection box 20. The pipeline to be monitored in this embodiment refers to a pipeline that transports dangerous liquids that may leak (concentrated sulfuric acid is used as an example in this embodiment). The concentrated sulfuric acid leakage monitoring method in this embodiment is applied to a concentrated sulfuric acid leakage monitoring system. According to the working principle of the concentrated sulfuric acid leakage monitoring system described in the above embodiment, when the concentrated sulfuric acid in the pipeline to be monitored leaks, the leaked concentrated sulfuric acid will flow into the upper accommodating chamber 231 and mix with the water in the upper accommodating chamber 231 to generate heat. The generated heat is transferred to the temperature monitoring device 233 attached to the heat conducting plate 234 through the heat conducting plate 234. The temperature monitoring device 233 can obtain water temperature information (i.e., temperature information in this embodiment) by real-time collection of the temperature of water transferred by the heat conducting plate 234. By analyzing the temperature information, it is determined whether the water temperature has risen within a period of time. If the water temperature has risen within a period of time, it can be determined that the concentrated sulfuric acid has leaked.

[0061] The temperature of the water in the upper accommodating chamber 231 is obtained by a temperature monitoring device 233 (for example, a temperature sensor). When it is detected that the temperature of the water in the upper accommodating chamber 231 rises by a certain temperature (for example, 5 degrees) within a certain time (for example, 2 seconds), the concentrated sulfuric acid leakage monitoring program will determine that a leak has occurred at a certain connection of the monitored pipeline corresponding to the upper accommodating chamber 231. Specifically, the water temperature must rise by a certain degree of time before the concentrated sulfuric acid leakage monitoring program determines that a leak has occurred. This is obtained after many experiments. The data in this embodiment is only used for illustration. By establishing an identification number for each temperature sensor, the temperature information received by the concentrated sulfuric acid leakage monitoring program will include the identification number of the temperature sensor, and then the specific position of the temperature sensor that sends the temperature information is determined through the identification number, and finally the leakage point is determined. The purpose of outputting the prompt information is to prompt maintenance personnel of the leakage situation and leakage point of the monitored pipeline.

[0062] This embodiment determines whether a dangerous liquid leak occurs by acquiring the water temperature in the water tank in real time, thereby realizing the automation of concentrated sulfuric acid leakage monitoring.

[0063] See also Figure 5 In another embodiment of the concentrated sulfuric acid leakage monitoring method of the present invention, the steps after step S30 include:

[0064] Step S40, when feedback information generated based on the prompt information is received, controlling the barrier device to be opened or closed to discharge the water in the upper accommodating chamber.

[0065] Step S50, when it is detected that the water in the upper accommodating chamber is emptied, controlling the water supply pipe to inject water into the upper accommodating chamber.

[0066] In this embodiment, when a dangerous liquid leaks at a certain connection, the concentrated sulfuric acid leakage monitoring program will not only output a prompt message, but also control the opening or closing of the barrier device 24. From the description of the barrier device 24 in the above embodiment, it can be seen that the function of the barrier device 24 is to control the water supply pipe 30 to transport water to the upper accommodating chamber 231. When there is no leakage at the connection, that is, the initial state of this scheme, the upper accommodating chamber 231 stores water, the barrier device 24 is closed, and the water supply pipe 30 cannot transport water to the upper accommodating chamber 231. When leakage occurs at the connection, leaked dangerous liquid will flow into the upper accommodating chamber 231, thereby heating the water in the upper accommodating chamber 231 and increasing the amount of water in the upper accommodating chamber 231. When the concentrated sulfuric acid leakage monitoring program issues a prompt message, the barrier device will be controlled to open and water will be supplied to the upper accommodating chamber 231 through the water supply pipe 30. Finally, by continuously supplying water to the upper accommodating chamber 231, the content of concentrated sulfuric acid in the upper accommodating chamber 231 is diluted, thereby achieving the purpose of reusing the water in the upper accommodating chamber 231.

[0067] In this embodiment, multiple uses of the concentrated sulfuric acid leakage monitoring system are achieved by controlling the switch of the blocking device 24.

[0068] Since all the technical solutions of all the aforementioned embodiments are adopted, at least all the beneficial effects brought by the technical solutions of the aforementioned embodiments are obtained, which will not be described one by one here.
