[0001] This utility model relates to the field of aviation transport management technology, and in particular to a hazardous materials handling device for aviation transport safety management. Background Technology

[0002] Dangerous goods seized during air transport (such as flammable and explosive materials, corrosive chemicals, and toxic substances) must be disposed of quickly and safely. The current mainstream method is centralized incineration, which decomposes the hazardous components through high-temperature combustion.

[0003] However, high-temperature combustion presents the problem of exhaust pollution. During the combustion process, a large amount of sulfur oxides, nitrogen oxides, and incompletely burned volatile organic compounds are released, making it difficult to meet emission standards. Furthermore, the collection of combustion waste is also a problem that needs to be solved. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to provide a dangerous goods handling device for aviation transportation safety management, which can effectively decompose dangerous goods by high-temperature combustion and effectively absorb harmful substances in the waste gas generated.

[0006] To achieve the above objectives, this utility model proposes a hazardous materials handling device for aviation transport safety management, comprising a combustion treatment mechanism and an exhaust gas treatment mechanism. The combustion treatment mechanism includes a combustion chamber, a combustion flame plate, and a grate, wherein the combustion flame plate and the grate are both disposed inside the combustion chamber, with the combustion flame plate positioned below the grate. The top of the combustion chamber is equipped with a feed hopper door and an exhaust gas transmission pipe. The exhaust gas treatment mechanism includes an exhaust gas treatment box connected to the exhaust gas transmission pipe. The exhaust gas treatment box contains an interconnected spray chamber and a filter chamber. The spray chamber contains a spray plate, and the bottom of the spray chamber contains a wastewater tank. The top of the spray chamber is connected to the exhaust gas transmission pipe. The filter chamber contains a filter screen, and the top of the filter chamber contains an exhaust pipe.

[0007] Furthermore, the spray plate is vertically arranged on the inner wall of the spray chamber, and a spray pump is provided outside the spray chamber, with the outlet end of the spray pump connected to the inlet end of the spray plate.

[0008] Furthermore, an exhaust gas transfer port is provided between the spray chamber and the filter chamber, and the exhaust gas transfer port is located below the spray plate and above the sewage tank.

[0009] Furthermore, a flushing device is provided at the bottom of the filter screen, and an exhaust pump is provided at the bottom of the exhaust pipe.

[0010] Furthermore, the combustion flame plate is vertically attached to the inner wall of the combustion chamber, the inner wall of the combustion chamber is provided with an explosion-proof isolation wall, and the bottom of the combustion chamber is provided with a discharge hopper door.

[0011] Furthermore, a combustion supply mechanism is provided on one side of the combustion box, including a supply box located on one side of the combustion box. The supply box contains a gas cylinder and an oxygen cylinder. The gas cylinder and the oxygen cylinder are connected to a speed regulating valve at their respective outlets. The outlet of the speed regulating valve is connected to the combustion flame plate.

[0012] Beneficial effects: This utility model involves burning hazardous materials at high temperature in a combustion chamber. The resulting solid residue falls through a grate and is collected at the bottom of the combustion chamber. The generated waste gas is first transported through a waste gas transmission pipe to a spray chamber for spray degradation, where particulate matter in the waste gas is absorbed. Wastewater enters a sewage tank to transfer wastewater. The waste gas then passes through a filter screen in a filtration chamber for secondary filtration and adsorption of harmful gases, ensuring thorough treatment of the waste gas. This effectively decomposes hazardous materials through high-temperature combustion and effectively absorbs harmful substances generated in the waste gas.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following description, in conjunction with the accompanying drawings, describes an embodiment of the hazardous materials handling device for aviation transport safety management according to the present invention.

[0020] like Figure 1 and Figure 2 As shown in the figure, the hazardous materials handling device for aviation transport safety management provided in this embodiment of the utility model includes a combustion treatment mechanism 2 and an exhaust gas treatment mechanism 3. The combustion treatment mechanism 2 includes a combustion chamber 22, a combustion flame plate 25 and a grate 27. The combustion flame plate 25 and the grate 27 are both arranged inside the combustion chamber 22. The combustion flame plate 25 is arranged below the grate 27. The top of the combustion chamber 22 is provided with a feed hopper door 21 and an exhaust gas transmission pipe 24.

[0021] The exhaust gas treatment mechanism 3 includes an exhaust gas treatment box 33 connected to the exhaust gas transmission pipe 24. The exhaust gas treatment box 33 has a spray chamber 34 and a filter chamber 39 that are interconnected. The spray chamber 34 has a spray plate 35 inside and a sewage tank 36 at the bottom. The top of the spray chamber 34 is connected to the exhaust gas transmission pipe 24. The filter chamber 39 has a filter screen 38 inside and an exhaust pipe 32 at the top.

[0022] Specifically, when using the hazardous materials handling device of this application, the hazardous materials are fed into the combustion chamber 22 through the feed hopper door 21, the hazardous materials are placed on the grate 27, the feed hopper door 21 is closed, and then the combustion flame plate 25 is ignited to generate a high-temperature flame, which burns the hazardous materials on the grate 27 at high temperature. The solid residue generated during the combustion process falls through the grate 27 and is collected at the bottom of the combustion chamber 22.

[0023] The generated waste gas is first transmitted to the spray chamber 34 through the waste gas transmission pipe 24. The waste gas is sprayed with degradation liquid through the spray plate 35 to degrade the waste gas and absorb the harmful particulate matter in the waste gas. The wastewater enters the sewage tank 36 for collection under gravity. Then the waste gas enters the filter chamber and passes through the filter screen 38 in the filter chamber 39 for secondary filtration and adsorption of harmful gases in the waste gas, so that the waste gas is fully treated and finally meets the emission standards and is discharged from the exhaust pipe 32.

[0024] In one embodiment of this utility model, such as Figure 1 and Figure 2As shown, the spray plate 35 is vertically arranged on the inner wall side of the spray chamber 34, and the spray pump 31 is arranged outside the spray chamber 34. The water outlet end of the spray pump 31 is connected to the water inlet end of the spray plate 35.

[0025] Specifically, after the exhaust gas enters the spray chamber 34 through the exhaust gas transmission pipe 24, the exhaust gas accumulates downward and is continuously transmitted downward. The vertical spray plate 35 sprays degradation liquid onto the passing exhaust gas to degrade the exhaust gas and absorb the harmful particulate matter in the exhaust gas. During the spraying process, the spray plate 35 is fed with degradation liquid by the spray pump 31.

[0026] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a waste gas transfer port 37 is provided between the spray chamber 34 and the filter chamber 39. The waste gas transfer port 37 is located below the spray plate 35 and above the sewage tank 36. This allows the waste gas to be fully sprayed and degraded through the spray plate 35. Subsequently, the sprayed waste gas enters the filter chamber 39 and gradually moves upward for filtration. During the filtration process, the filter screen 38 is washed by the washer 381 to remove the dirt accumulated on its surface. Finally, the gas is quickly extracted by the exhaust pump 321.

[0027] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the combustion flame plate 25 is vertically attached to the inner wall of the combustion chamber 22, the inner wall of the combustion chamber 22 is provided with an explosion-proof isolation wall 26, and the bottom of the combustion chamber 22 is provided with a discharge chamber door 23.

[0028] Specifically, the solid residue produced after combustion in the combustion chamber 22 falls to the bottom of the combustion chamber 22 through the grate 27, and can be periodically removed by opening the discharge hopper door 23. The explosion-proof isolation wall 26 on the inner wall of the combustion chamber 22 protects against the combustion of hazardous materials and prevents explosion damage to the combustion chamber 22. The combustion flame plate 25 is vertically attached to the inner wall of the combustion chamber 22 to reduce dust falling on its surface.

[0029] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a combustion supply mechanism 1 is provided on one side of the combustion box 22, including a supply box 11 provided on one side of the combustion box 22. A supply box door 12 is provided on one side of the supply box 11. A gas cylinder 13 and an oxygen cylinder 14 are installed inside the supply box 11 through a tank bracket 15. A speed regulating valve 16 is provided at the gas outlet of the gas cylinder 13 and the oxygen cylinder 14. The gas outlet of the speed regulating valve 16 is connected to the combustion flame plate 25.

[0030] Specifically, when the combustion flame plate 25 is working, the gas tank 13 and the oxygen tank 14 supply gas and oxygen to support combustion, respectively, and transmit the gas to the combustion flame plate 25 for combustion. During this period, the gas and oxygen are regulated by the speed regulating valve 16, thereby regulating the size of the combustion flame.

[0031] To clearly illustrate the above embodiments, refer to Figure 1 and Figure 2 The working principle of the hazardous materials handling device for aviation transport safety management of this utility model is as follows: When using the hazardous materials handling device of this application, the hazardous materials are first sent into the combustion chamber 22 through the feed hopper door 21, the hazardous materials are placed on the grate 27 for combustion, and then the feed hopper door 21 is closed.

[0032] Subsequently, the gas cylinder 13 and the oxygen cylinder 14 supply gas and oxygen respectively, and transmit the gas to the combustion flame plate 25 for combustion. The combustion flame plate 25 is ignited to generate a high-temperature flame, which burns the hazardous materials on the grate 27 at high temperature. The solid residue generated during the combustion process falls through the grate 27 and is collected at the bottom of the combustion chamber 22.

[0033] The generated waste gas enters the spray chamber 34 through the waste gas transmission pipe 24 and accumulates downwards. At this time, the spray pump 31 sends the degradation liquid into the spray plate 35. The vertical spray plate 35 sprays the degradation liquid horizontally onto the waste gas being transported downwards, thereby spraying and degrading the waste gas, cooling it, and absorbing harmful particulate matter in the waste gas. The generated wastewater is collected in the sewage tank 36 by gravity and discharged through the sewage pipe 361.

[0034] The sprayed exhaust gas then enters the filter chamber 39 and moves upwards for filtration. The filter screen 38 in the filter chamber 39 performs secondary filtration and adsorption of harmful gases in the exhaust gas, so that the exhaust gas is fully treated and finally meets the emission standards. The exhaust gas is then quickly extracted by the exhaust pump 321.

[0035] In summary, the hazardous materials handling device for aviation transport safety management according to this utility model involves burning hazardous materials at high temperature in a combustion chamber. The resulting solid residue falls through a grate to the bottom of the combustion chamber for collection. The generated waste gas is first transported to a spray chamber through a waste gas transmission pipe for spray degradation, absorbing particulate matter in the waste gas. Wastewater enters a sewage tank to transfer sewage. The waste gas then passes through a filter screen in a filtration chamber for secondary filtration and adsorption of harmful gases, thus ensuring that the waste gas is fully treated.

[0036] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
