[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Figure 1 Schematically shows the system architecture of a method and device for constructing an image semantic segmentation model applicable to the embodiments of the present invention.

[0029] Refer to Figure 1 As shown, the embodiments of the present invention provide a chemical production safety relief treatment device, including:

[0030] A safety relief tank 1 for containing materials that need to be relieved during chemical production;

[0031] A deionized water tank 2 provided on one side of the safety relief tank 1 for supplying deionized water to the safety relief tank 1;

[0032] A treatment mechanism provided inside the safety relief tank 1, which combines the deionized water stored and supplemented in the safety relief tank 1 to achieve gas-liquid two-phase separation and cooling absorption of the relieved materials;

[0033] A torch system 3 and a material handling unit 4. The torch system 3 is provided on one side of the safety relief tank 1, and the material handling unit 4 is provided on the other side of the safety relief tank 1. The torch system 3 is used for relieving and treating the gas in the safety relief tank 1, and the material handling unit 4 is used for recycling and treating the recycled materials condensed and absorbed in the safety relief tank 1.

[0034] Among them, in the event of a chemical accident, the discharged material enters the safety relief tank 1. At this time, the deionized water tank 2 transports deionized water into the safety relief tank 1 through a pipeline. The treatment mechanism combines the deionized water stored and supplemented in the safety relief tank 1 to achieve gas-liquid two-phase separation and cooling absorption of the discharged material. The discharged material is absorbed and condensed in the safety relief tank 1, and the gas rises and enters the flare system 3 from the safety relief tank 1. The flare system 3 processes the gas. The recovered material condensed is recovered and processed by the material processing unit 4.

[0035] It should be noted that the flare system 3 is a special combustion facility used to treat combustible and combustible toxic gases and vapors that cannot be recovered and reprocessed in petrochemical plants, refineries, chemical plants and other factories or installations. It is an important measure to ensure the safe production of factories and reduce environmental pollution. The flare system 3 is divided into elevated flares and ground flares. The form of the flare to be adopted is determined according to factors such as the designed treatment capacity of the flare system, the geographical conditions of the factory location, and the environmental protection requirements. Since the flare system 3 is a commonly used technical implementation method in this field and belongs to the existing conventional technology, the specific structure of the flare system 3 is not described in detail in this application, as long as it can achieve the technical effects that this application can achieve.

[0036] Secondly, it should be noted that the discharged material is a high-temperature gas-liquid two-phase material. The discharged high-temperature gas-liquid two-phase material is input into the safety relief tank 1, and the discharged high-temperature gas-liquid two-phase material reacts in the safety relief tank 1.

[0037] In this embodiment, the deionized water tank 2 is connected with a makeup water pump 5 through a pipeline. The makeup water pump 5 is connected with the safety relief tank 1 through a pipeline. The makeup water pump 5 is used to transport the deionized water in the deionized water tank 2 into the safety relief tank 1 through the pipeline.

[0038] Among them, the makeup water pump 5 is set. When the discharged high-temperature gas-liquid two-phase material is input into the safety relief tank 1, the makeup water pump 5 starts, and the deionized water in the deionized water tank 2 is transported into the safety relief tank 1 through the transportation of the makeup water pump 5. The deionized water in the deionized water tank 2 is transported into the safety relief tank 1 by using a pipeline, so that the deionized water is combined with the discharged high-temperature gas-liquid two-phase material in the safety relief tank 1. Then, the treatment mechanism combines the deionized water stored and supplemented in the safety relief tank 1 to achieve gas-liquid two-phase separation and cooling absorption of the discharged material.

[0039] In this embodiment, a material temperature measuring unit 6 is installed on the pipeline between the makeup water pump 5 and the safety relief tank 1. The material temperature measuring unit 6 is used to monitor the condition in the safety relief tank 1 and starts the makeup water pump 5 to transport deionized water into the safety relief tank 1 when the discharged material enters the safety relief tank 1.

[0040] Among them, when the material temperature measuring unit 6 is set to judge whether the discharged high-temperature gas-liquid two-phase material is input into the safety relief tank 1, the material temperature measuring unit 6 and the makeup water pump 5 are interlocked to ensure that the makeup water pump 5 can be started before the discharged material enters the safety relief tank 1, and the makeup water pump 5 will not be misstarted when there is no discharged material, so as to effectively control the transportation and stop of external deionized water.

[0041] In this embodiment, the material temperature measuring unit 6 and the makeup water pump 5 are interlocked. The makeup water pump 5 can be started before the discharged material enters the safety relief tank 1, and the makeup water pump 5 will not be misstarted when there is no discharged material, so as to effectively control the transportation and stop of external deionized water.

[0042] In this embodiment, the material temperature measuring unit 6 can be a thermometer. The thermometer is used to monitor the temperature in the safety relief tank 1. When the temperature changes, it means that the discharged high-temperature gas-liquid two-phase material has entered the safety relief tank 1 at this time. Then the makeup water pump 5 is turned on, and the deionized water in the deionized water tank 2 is transported through the makeup water pump 5, and the deionized water in the deionized water tank 2 is transported into the safety relief tank 1 through a pipeline, so that the deionized water is combined with the discharged high-temperature gas-liquid two-phase material in the safety relief tank 1, and then the treatment mechanism combines the deionized water stored and supplemented in the safety relief tank 1 to achieve gas-liquid two-phase separation and cooling absorption of the discharged material.

[0043] It should be noted that the material temperature measuring unit 6 is not limited to a thermometer, and other devices can be used as long as they can understand the situation in the safety relief tank 1 and know when the discharged high-temperature gas-liquid two-phase material has entered the safety relief tank 1 at this time, as long as the above functions can be achieved, which is convenient for timely controlling the opening and stop of the makeup water pump 5.

[0044] In this embodiment, the treatment mechanism is a distributor 7. The distributor 7 is arranged inside the safety relief tank 1, and the distributor 7 is used to combine the deionized water stored and supplemented in the safety relief tank 1 to achieve gas-liquid two-phase separation and cooling absorption of the discharged material.

[0045] Among them, the treatment mechanism is a distributor 7. The distributor 7 refers to a liquid distribution device arranged at the top of the packed tower. Its function is to evenly distribute the liquid across the tower cross-section, thus ensuring high-efficiency operation. Common operation distributors include: shower head type, impact type, pagoda type, multi-hole pipe type, multi-hole coil type, overflow tray type and overflow trough type. When the sprayed liquid flows downward along the packing layer, it cannot maintain the original uniform distribution state and has a phenomenon of flowing towards the tower wall, which affects the contact between the gas and liquid phases and reduces the mass transfer efficiency. Therefore, the packing layer must be segmented, and a liquid redistributor is arranged between two sections of the packing layer to enable the liquid to flow evenly to the lower layer.

[0046] In this application, the distributor 7 is placed inside the safety relief tank 1. The distributor 7 in this application adopts a porous pipe type, enabling the liquid inside the safety relief tank 1 to be evenly distributed, thereby ensuring high-efficiency operation. The reaction efficiency between the discharged high-temperature gas-liquid two-phase material and the material inside the safety relief tank 1 is improved.

[0047] In this embodiment, a pipeline is installed outside the safety relief tank 1, and the discharged material enters from the middle of the safety relief tank 1 through the pipeline. Combining with the distributor 7 installed inside the safety relief tank 1 and the deionized water stored and supplemented in the safety relief tank 1, gas-liquid two-phase separation and cooling absorption of the discharged material are achieved.

[0048] Among them, a pipeline is arranged at one end in the middle of the safety relief tank 1, and the discharged high-temperature gas-liquid two-phase material is input into the safety relief tank 1 through this pipeline. Then, combining with the distributor 7 installed inside the safety relief tank 1 and the deionized water stored and supplemented in the safety relief tank 1, gas-liquid two-phase separation and cooling absorption of the discharged material are achieved.

[0049] In this way, when an accident occurs, it is avoided that a large amount of gas-liquid mixed hazardous materials are directly discharged only through the flare system 3, increasing the production load of the flare system 3. Or through a safety relief tank equipped with a fire-fighting steam pipe at the top for high-altitude discharge. However, since the discharged hazardous materials cannot be fully condensed, most of the discharged hazardous materials will be directly discharged into the air, which will not only cause serious environmental pollution but also easily lead to secondary accidents.

[0050] In this embodiment, when the discharged material enters the safety relief tank 1 and combines with the distributor 7 installed inside the safety relief tank 1 and the deionized water stored and supplemented in the safety relief tank 1, a reaction occurs to generate gas. The gas includes non-condensable gas and water vapor. A gas phase outlet 8 is provided at the top of the safety relief tank 1, and the gas phase outlet 8 is connected to the flare system 3 through a pipeline. The non-condensable gas and water vapor are transported to the flare system 3 through the pipeline via the gas phase outlet 8 at the top of the safety relief tank 1.

[0051] Among them, by setting the safety relief tank 1, the discharged material enters from the middle of the safety relief tank 1. During the process of the discharged material entering, by using the distributor 7 located inside the safety relief tank 1 and combining with the deionized water stored and supplemented in the safety relief tank 1, the purpose of gas-liquid two-phase separation and cooling absorption of the discharged material is achieved.

[0052] A gas phase outlet 8 is provided at the top of the safety relief tank 1. When a chemical accident occurs, the discharged high-temperature gas-liquid two-phase material enters through the material inlet pipe at the middle position of the safety relief tank 1, and at the same time triggers the temperature interlock to start the makeup water pump 5. The material inlet pipe is horizontally connected to the distributor 7 inside the safety relief tank 1. Then, the discharged high-temperature gas-liquid two-phase material is absorbed and condensed inside the safety relief tank 1, and the non-condensable gas rises to achieve gas-liquid two-phase separation. Finally, the non-condensable gas and water vapor are sent to the flare system 3 through the gas phase outlet 8, and the flare system 3 conducts relevant treatment on it.

[0053] In this embodiment, when the discharged material enters the safety relief tank 1, it reacts with the deionized water stored and supplemented in the safety relief tank 1 in combination with the distributor 7 installed inside the safety relief tank 1 to produce recovered material through condensation absorption. A recovered material outlet 9 is provided at the bottom of the safety relief tank 1. The recovered material outlet 9 is connected to the material treatment unit 4 through a pipeline. The material treatment unit 4 is a material treatment pump. The condensed and absorbed recovered material is transported to the material treatment pump through the recovered material outlet 9, and the dangerous discharged material is recycled through the material treatment pump.

[0054] Among them, when a chemical accident occurs, the discharged high-temperature gas-liquid two-phase material enters through the material inlet pipe at the middle position of the safety relief tank 1, and at the same time triggers the temperature interlock to start the makeup water pump 5. The material inlet pipe is horizontally connected to the distributor 7 inside the safety relief tank 1. Then, the discharged high-temperature gas-liquid two-phase material is absorbed and condensed inside the safety relief tank 1, and the non-condensable gas rises to achieve gas-liquid two-phase separation. Finally, the non-condensable gas and water vapor are sent to the flare system 3 through the gas phase outlet 8, and the flare system 3 conducts relevant treatment on it. When the reaction occurs, in addition to generating non-condensable gas and water vapor, recoverable material will also be generated through condensation. The condensed recovered material is discharged through the recovered material outlet 9 and input to the material treatment pump, and the dangerous discharged material is recycled through the material treatment pump.

[0055] The safety relief tank 1 is adopted to achieve the purpose of gas-liquid two-phase separation and cooling absorption of the discharged material during the process of the discharged material entering. The non-condensable gas and water vapor are transported to the flare system 3 through the gas phase outlet 8 at the top of the safety relief tank 1, thereby reducing the production load of the flare system 3; the condensed and absorbed recovered material is transported to the material treatment unit through the recovered material outlet 9 at the bottom of the safety relief tank 1 for recovered material treatment.

[0056] In this embodiment, one end of the safety relief tank 1 far from the transported discharged material is connected with a liquid level gauge 10 through a pipeline. The liquid level gauge 10 is used to measure the liquid level height of the condensed recovered material inside the safety relief tank 1, and control the opening and closing of the recovered material outlet 9 by measuring the liquid level height of the recovered material.

[0057] Among them, the condensed recycled material is controlled by the liquid level gauge 6 and output through the recycled material outlet 9 for recycling treatment.

[0058] The present invention provides a chemical production safety relief treatment device that uses a safety relief tank 1 to separate the gas-liquid phases of the relief material and cool and absorb it during the entry of the relief material. The non-condensable gas and water vapor are transported to the flare system 3 through the gas phase outlet 8 at the top of the safety relief tank 1, thereby reducing the production load of the flare system 3; the condensed and absorbed recycled material is transported to the material treatment unit 4 through the recycled material outlet 9 at the bottom of the safety relief tank 1 to achieve the safe relief and recycling of hazardous materials, which can not only reduce the production load of the flare system 3 but also save the raw materials and materials required for safety relief on the basis of ensuring production safety. Compared with the traditional relief scheme, it realizes the safe relief of hazardous materials, enables the chemical production system to operate safely, reduces the production load of the flare, and finally solves the environmental protection problem of chemical accident relief.
