Description

Technical Field

[0001] The utility model relates to the chemical industry field, and particularly relates to an emergency disposal simulation training device for leakage of a storage tank weld seam. Background Art

[0002] A certain liquid belongs to dangerous chemicals and is generally stored in a storage tank. During the storage and use processes, due to reasons such as equipment aging and damage, different degrees of leakage often occur. If not properly handled, secondary disasters such as explosion, fire, poisoning, chemical burns, and asphyxiation will occur.

[0003] The medium leakage phenomenon of this liquid is as follows: the medium continuously flows down or drips in a bead shape but does not reach the flowing degree; if the leaked medium is the vapor of a certain liquid, the noise emitted by the leaked gas can be heard. Medium leakage generally occurs at the side weld seam of the storage tank. The storage tank is a storage device for storing a certain liquid and operates under pressure. Due to the long storage time, leakage is likely to occur at the weld seam of the liquid tank, the connection of instrument valves, etc. Once any part of the tank body in contact with the liquid is damaged, liquid will leak out. Due to the relatively fast leakage of medium leakage, the risk of secondary disasters is relatively high. It is necessary to design a disposal practice device for simulation operation practice to improve the emergency disposal ability of students. Content of the Utility Model

The following description of the preferred embodiments will involve combinations of features, which may exist independently or in combination. The present utility model is not particularly limited to the preferred embodiments. The scope of the present utility model is defined by the claims.

[0053] As Figure 1 Shown in the figure, is an emergency disposal simulation training device for the leakage of the weld of a storage tank according to an embodiment of the present utility model, including a storage tank 1, a leakage liquid flow simulation device and a control cabinet 5. The storage tank 1 is a horizontally placed liquid tank with equal ratio scaling. The horizontally placed storage tank is welded with mirror stainless steel components. Installation flanges are provided on the storage tank, and components such as safety valves, pressure gauges, blind plates, liquid level gauges, and manholes are installed.

The liquid tank 2 is arranged inside the storage tank 1, and the liquid tank 2 is filled with a simulation medium. The gas cylinder 3 is connected to the air inlet of the liquid tank 2 through a gas supply pipeline 7, and is used to supply gas to the liquid tank 2 for pressurization and provide gas detection gas for gas detection at the leakage point. Compressed gas is injected into the liquid tank 2 through the gas cylinder 3 to increase the pressure inside the liquid tank 2 and squeeze out the simulation medium inside the liquid tank 2. A liquid tank air release control valve 201 and a liquid tank pressure detection device 202 are arranged on the liquid tank 2. The liquid tank air release control valve 201 is arranged at the air release port on the liquid tank 2. The liquid tank pressure detection device 202 is used to monitor the pressure condition inside the liquid tank 2. The liquid tank air release control valve 201 is used to release air from the liquid tank 2 when the pressure inside the liquid tank 2 is too high.

[0056] The inlet end of the leakage simulation pipeline 4 is connected to the liquid outlet of the liquid tank 2, and the outlet end of the leakage simulation pipeline 4 is arranged at the leakage point. A leakage point control valve 401 and a leakage regulating valve 402 are arranged at the outlet end of the leakage simulation pipeline 4. Whether the simulation medium leaks at the leakage point is controlled through the leakage point control valve 401, and the flow rate of the simulation medium inside the leakage simulation pipeline 4 is adjusted through the leakage regulating valve 402, thereby adjusting the size of the simulation medium leakage amount at the leakage point.

[0057] A filter 701, a gas source control valve 702, a gas source pressure detection device 703, a pressure reducer 704, a pressure detection device 705 after the pressure reducer, and a liquid tank inflation control valve 706 are arranged on the gas supply pipeline 7. The filter 701 is used to filter the gas entering the gas supply pipeline 7; the inlet end of the gas source control valve 702 is connected to the outlet of the gas cylinder 7 through the filter 701 and is used to control the on-off condition of the gas supply pipeline 7; the gas source pressure detection device 703 is arranged at the outlet end of the gas source control valve 702 and is used to monitor the outlet pressure of the gas cylinder 3; the inlet end of the pressure reducer 704 is connected to the outlet end of the gas source control valve 702, and the outlet end of the pressure reducer 704 is connected to the inlet end of the liquid tank inflation control valve 706 and is used to reduce the pressure of the gas inside the gas supply pipeline. The pressure detection device 705 after the pressure reducer is connected to the outlet end of the pressure reducer 704 and is used to monitor the pressure of the decompressed gas; the liquid tank inflation control valve 706 is used to control the gas supply pipeline to supply gas to the liquid tank 2.

[0058] The inlet end of the gas detection pipeline is connected to the gas supply pipeline 7 through a gas detection gas supply valve. The gas detection gas supply valve is a three-way valve. The inlet end of the gas detection gas supply valve is connected to the outlet end of the pressure reducer 704. The first outlet end of the gas detection gas supply valve is connected to the inlet end of the gas detection pipeline, and the second outlet end of the gas detection gas supply valve is connected to the inlet end of the liquid tank inflation control valve 706 and is used to control the on-off condition of the gas detection pipeline and the gas supply pipeline 7.

[0059] In this embodiment, the emergency disposal simulation training device for the leakage of the storage tank weld also includes a base 6. A waste liquid collection device 602 is arranged on the base 6. The waste liquid collection device 602 includes a grid plate (not shown in the figure) and a liquid collection tray arranged below the grid plate. The storage tank 1 is arranged on the top surface of the grid plate through a storage tank support 601. The liquid collection tray is arranged below the storage tank 1 and on both sides of the storage tank support 601, and is used for collecting the waste liquid of the leakage point leakage liquid flow simulation device.

[0060] The control cabinet 5 is used to control the simulation process of leakage and disposal. The control cabinet 5 includes a cabinet body and a control panel arranged on the cabinet body. A control device is arranged in the cabinet body. The control device can be a PLC controller. The control panel is electrically connected to the PLC controller. To improve the integration of the simulation device, the gas cylinder 3 is arranged on the side surface of the cabinet body, and all or part of the gas supply pipeline and the gas detection pipeline can be arranged in the cabinet body. The control cabinet 5 can be arranged on the top surface of the base 6 or on one side of the base 6.

[0061] The control panel is provided with a gas source valve control button 501, a pressure reducer control button 503, a liquid tank inflation button 505, a liquid tank deflation button 506, a pressure display device 504 after the pressure reducer, a liquid tank pressure display device 507 and a leakage point selection button 508, which are used to control the valves on the pipeline and display the pressure of the pressure detection device. The pressure display device can be the dial of a pressure gauge.

[0062] The control panel is also provided with a storage tank simulation pressure display device 502. The storage tank simulation pressure display device 502 is connected to the pressure detection device on the gas detection pipeline and is used to display the pressure of the gas detection pipeline. When gas detection is carried out, if the indication of the storage tank simulation pressure display device 502 is significantly lower than the normal value, it indicates that there is still a leakage problem at the leakage point and the disposal of the leakage point is unqualified. Thus, the storage tank simulation pressure display device 502 simulates the pressure change of the storage tank after the disposal of the leakage point in the real leakage point disposal scenario, so as to assist in judging the qualification of the leakage point disposal.

[0063] The gas supply pipeline 7 is communicated with the air inlet of the liquid tank 2, and the air inlet condition of the liquid tank 2 is controlled by a liquid tank inflation control valve 706; the liquid tank pressure display device 507 is used to display the pressure condition in the liquid tank 2 in real time; the liquid tank deflation button 506 is electrically connected to the liquid tank deflation control valve 201 on the liquid tank 2, so as to deflate the liquid tank 2 when the liquid tank pressure display device 507 shows that the pressure in the liquid tank 2 is too high.

[0064] The leakage point selection button 508 is arranged in one-to-one correspondence with the leakage regulating valve 402 and is used to control the opening and closing of the leakage regulating valve 402 to realize the selection of the leakage point.

[0065] The control panel is also provided with a practice mode button 509 and a practice status indicator light 510. The practice mode button 509 is used to turn on the practice mode and start the next step in the practice mode; the practice status indicator light 510 is set in one-to-one correspondence with the steps of post-processing in the practice mode. The practice status indicator light 510 is used to indicate the current status. The trainee can switch the indicator light through the practice simulation button. The lighting sequence of the practice status indicator light 510 is the same as the steps of post-fault handling. The trainee can practice the processing flow according to the lighting sequence of the practice status indicator light 510. The disposal after the occurrence of a medium leak fault at the leakage point includes processes such as bandaging and drainage, pressure relief, plugging and defect elimination, decontamination, and re-gas inspection.

[0066] The control panel is provided with a gas inspection button. By controlling the gas inspection air supply valve through the gas inspection button, the on-off control of the leakage simulation pipeline and the gas inspection pipeline is realized, which is convenient for students to conduct gas inspection after the fault handling of the leakage liquid flow simulation device is completed.

[0067] To enhance the immersion of the practice, the storage tank 1 is also equipped with a smoke simulation system and a lighting simulation system. The smoke simulation system includes a smoke pipeline, one end of which is connected to a smoke machine, and the other end is arranged at the leakage point. The smoke machine and the lighting simulation system are controlled by the control cabinet 5 and are used to simulate the smoke and lighting in a real leakage scenario. The leakage simulation of a certain liquid can be realized, so as to create a highly immersive practice environment; in addition, an acidulant can be added to the smoke during on-site practice, making the smell closer to the on-site environment during leakage, and further improving the realism of the practice environment.

[0068] As Figure 4 shown, in this embodiment, the principle of controlling the small leakage of the medium in the simulation storage tank 1 by the control cabinet 2 is as follows: the simulated liquid flow comes from the liquid tank 2 inside the simulation storage tank 1. Before the practice, the simulated leakage medium is poured into the liquid tank 2 in the simulation storage tank 1, and the volume of the poured simulated medium accounts for about half of the volume of the liquid tank 2. Compressed gas in the gas cylinder 3 is used to pressurize the liquid tank 2, and the compressed gas in the liquid tank 2 provides power for the simulated medium. When the leakage regulating valve 402 is opened, the simulated medium starts to leak from the designed leakage point, and the leakage size can be adjusted by the pressure of the liquid tank 2 and the opening of the leakage regulating valve 402.

[0069] The gas cylinder 3 is fixed on the side of the control cabinet 5 and is used to provide a stable gas source. The control cabinet 5 is connected according to the designed pipeline diagram. The console panel is equipped with a pressure detection device, a pressure reducer, a leak point selection button 508, and a practice status indicator light 510. The corresponding leakage point is selected through the button for practice, and the indicator light can indicate the current practice stage. The on-off of the liquid in the specified pipeline is controlled by the leakage point control valve 401 automatically controlled by the program. The pressure detection device on the leakage simulation pipeline 4 can clearly and intuitively detect the magnitude of the pressure value of the relevant pipeline.

[0070] The liquid flow control is achieved through the leakage point control valve 401 and the leakage regulating valve 402. The leakage regulating valve 402 is used to regulate the leakage speed of the simulated medium, and the leakage point control valve 401 is used to control the on-off of the medium for process switching. In the air inspection link, the liquid path of the simulated leakage point is disconnected, and the air inspection control valve is opened to conduct air inspection of the leakage point. If the treatment of the leakage point is unqualified, it can be detected by the soap bubble method during the air inspection process.

[0071] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
