DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0050] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0051] The exhaust gas treatment equipment and method provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0052] like Figures 1 to 7 As shown, an embodiment of the present application provides a waste gas treatment device, including a mounting box, a sensing component, and a control unit 200, a drying adsorption component 400, a washing and mixing unit 600, and a vacuum suction unit 700 fixedly arranged on the mounting box.

[0053] The air inlet end of the scrubbing mixing unit 600 is connected to the exhaust gas inlet 500, and the exhaust end is connected to the air inlet end of the vacuum suction unit 700. The air inlet end of the drying adsorption component 400 is connected to the exhaust end of the vacuum suction unit 700, and the exhaust end is connected to the exhaust port 800.

[0054] The sensing component includes a weather sensing unit 310, a humidity sensing unit 320, and a flow metering unit 330. The weather sensing unit 310 is fixedly mounted on the mounting box and can obtain weather status information within a predetermined time. The humidity sensing unit 320 is used to obtain humidity information of the exhaust gas collected by the vacuum suction unit 700. The flow metering unit 330 is used to obtain instantaneous flow information of the exhaust gas collected by the vacuum suction unit 700.

[0055] Among them, the scheduled time is specifically the preset exhaust gas automatic processing time. The control unit 200 is coupled with the sensing component and can record the weather status information, humidity information, and instantaneous flow information obtained by the sensing component. It can also control the opening and closing state of the vacuum suction unit 700 based on the scheduled time and weather status information.

[0056] It is understandable that within the predetermined time, the weather sensing unit 310 automatically starts and obtains weather status information. When the control unit 200 determines that the weather status information does not meet the standard, the vacuum suction unit 700 is controlled to be in a closed state. When the control unit 200 determines that the weather status information meets the standard, the vacuum suction unit 700 is controlled to be in an open state. At this time, the vacuum suction unit 700 collects exhaust gas through the gas washing mixing unit 600 and the exhaust gas inlet 500, and inputs the exhaust gas to the dry adsorption component 400. The dry adsorption component 400 filters the collected exhaust gas and discharges the exhaust gas through the exhaust port 800. During this process, the humidity sensing unit 320 and the flow metering unit 330 respectively obtain the humidity information and instantaneous flow information of the collected exhaust gas, and send the humidity information and instantaneous flow information to the control unit 200.

[0057] In an embodiment of the present application, an exhaust gas treatment device as described above is used to obtain weather status information within a predetermined time, and automatically perform exhaust gas collection and filtration processing when the weather status information meets the standard. During the exhaust gas treatment process, its humidity information and instantaneous flow information are monitored and recorded in real time, which is conducive to subsequent data collation and tracing, while reducing human intervention and operational errors, improving the accuracy and reliability of detection, and being able to complete tritium detection in a short time, effectively improving sampling efficiency. It can be applied to nuclear energy research, medicine, scientific research and other fields to solve various technical problems regarding tritium isotope separation, concentration detection, safe isolation and resource recycling.

[0058] In a preferred embodiment, the control unit 200 can record the sampling time of the vacuum suction unit 700, and can also calculate and record the collected exhaust gas cumulative flow information based on the sampling time and the collected exhaust gas instantaneous flow information.

[0059] In a preferred embodiment, the control unit 200 can output an alarm message when the humidity information exceeds a predetermined humidity threshold.

[0060] The predetermined humidity threshold is specifically a preset exhaust gas humidity range.

[0061] It is understandable that when the humidity information of the collected exhaust gas exceeds the predetermined humidity threshold, the treatment effect of the dry adsorption component 400 on the collected exhaust gas is poor. The control unit 200 outputs an alarm message, which enables the operator to deal with the source of the exhaust gas in a timely manner.

[0062] In a preferred embodiment, Figure 3 , Figure 4 As shown, the humidity sensing unit 320 is fixedly disposed on the mounting box and coupled to the scrubbing and mixing unit 600 .

[0063] In a preferred embodiment, Figure 3 , Figure 4 As shown, the air inlet end of the flow metering unit 330 is connected to the air outlet end of the vacuum suction unit 700 , and the air outlet end is connected to the air inlet end of the drying adsorption assembly 400 .

[0064] It is understandable that the setting form of the flow metering unit 330 is not limited to the above-mentioned one. For example, the flow metering unit 330 can be set between the gas washing mixing unit 600 and the vacuum suction unit 700. As long as the instantaneous flow information of the collected exhaust gas can be obtained, it will not be elaborated here.

[0065] In a preferred embodiment, Figure 1 , Figure 3 , Figure 4 As shown, the control unit 200 includes a control module 210 fixedly disposed on a mounting box and a display panel 220 coupled to the control module 210 .

[0066] The control module 210 can visually display the humidity information, sampling time, instantaneous flow information, and accumulated flow information of the collected exhaust gas through the display panel 220 .

[0067] In a preferred embodiment, Figures 1 to 6 As shown, the dry adsorption component 400 includes a mounting plate 420 detachably connected to a mounting box, and at least one processing tank 410 is fixedly provided on the mounting plate 420. A filter cavity 411 for filling a filter material 900 is provided in the processing tank 410, and flow holes 413 are respectively provided between the inner walls on both sides of the axial direction of the processing tank 410 and the corresponding ends of the processing tank 410.

[0068] Among them, the processing tank 410 is fixedly provided with a mounting plate 420, and the flow hole 413 at one end of the processing tank 410 is connected to the exhaust port 800 through the exhaust pipe 440, and the flow hole 413 at the other end is connected to the exhaust end of the vacuum suction unit 700 through the air inlet pipe 450.

[0069] Alternatively, a plurality of treatment tanks 410 are fixedly provided on the mounting plate 420, and the filter chambers 411 and the flow holes 413 of the plurality of treatment tanks 410 are connected in series in a non-closed manner through the connecting pipe 430, and the flow holes 413 at one end of the plurality of series-connected treatment tanks 410 are connected to the exhaust port 800 through the exhaust pipe 440, and the flow holes 413 at the other end are connected to the exhaust end of the vacuum suction unit 700 through the air inlet pipe 450.

[0070] It can be understood that the non-closed series connection means that the multiple processing tanks 410 are arranged in a non-annular series connection.

[0071] In a preferred embodiment, Figure 5 , Figure 6 As shown, a plurality of spoilers 412 are fixedly disposed on the inner wall of the filter cavity 411 , which are arranged at intervals along the axial direction of the processing tank 410 and are parallel to each other, and two adjacent spoilers 412 are arranged in a staggered manner about the central axis of the processing tank 410 .

[0072] A transition gap is provided between the distal end of the spoiler 412 and the inner wall of the corresponding side of the filter cavity 411 .

[0073] It can be understood that the distal end of the spoiler 412 refers to the end of the spoiler 412 away from the connection portion between the spoiler 412 and the inner wall of the filter chamber 411. Since the multiple spoilers 412 are staggered along the central axis of the treatment tank 410, the transition gaps of the multiple spoilers 412 are staggered. When the collected exhaust gas flows from the flow hole 413 on one side of the treatment tank 410 to the flow hole 413 on the other side, the collected exhaust gas passes through the multiple transition gaps in the filter chamber 411 in turn, and the separation of tritium gas and tritiated water vapor is achieved through the filter material 900 in the filter chamber 411.

[0074] In an embodiment of the present application, the above-mentioned exhaust gas treatment equipment is adopted, and the staggered arrangement of spoilers 412 can extend the flow path of the collected exhaust gas in the filter cavity 411, thereby increasing the reaction time between the collected exhaust gas and the filter material 900 and ensuring the treatment effect of the collected exhaust gas.

[0075] In a preferred embodiment, Figure 5 , Figure 6 As shown, the processing tank 410 includes a tank body 4101 and two end seats 4102 respectively fixedly arranged at both ends of the tank body 4101.

[0076] The filter chamber 411 is axially penetrated in the tank body 4101 , the two end seats 4102 respectively block the two end openings of the tank body 4101 , and the flow hole 413 is penetrated on the end seat 4102 and communicated with the filter chamber 411 .

[0077] In a preferred embodiment, Figure 5 , Figure 6 As shown, an embedding cavity 4103 is provided at one end of the end seat 4102 close to the tank body 4101 , and the tank body 4101 is embedded in the embedding cavity 4103 and is threadedly connected to the inner wall of the embedding cavity 4103 .

[0078] In a preferred embodiment, Figure 5 , Figure 6 As shown, a sealing ring 470 is provided in the embedding cavity 4103 and surrounds the opening at the corresponding end of the filter cavity 411 .

[0079] In the axial direction of the tank body 4101 , two ends of the sealing ring 470 are respectively in contact with the inner wall of the embedding cavity 4103 on the side away from the tank body 4101 and the corresponding side end surface of the tank body 4101 .

[0080] In a preferred embodiment, Figure 6 As shown, a bitumen plate 460 covering the flow hole 413 is clamped on the inner wall of the embedding cavity 4103 away from the tank body 4101.

[0081] It is understandable that the asphalt plate 460 can filter impurities from the collected waste gas passing through the filter chamber 411, thereby avoiding blockage in the connecting pipe 430 or the exhaust pipe 440 and the intake pipe 450.

[0082] In a preferred embodiment, the filter material 900 is specifically configured as a mixture of a desiccant and a catalyst.

[0083] In a preferred embodiment, the material of the tank body 4101 and the spoiler 412 is specifically set to be transparent acrylic.

[0084] It is understandable that when the collected exhaust gas reacts with the filter material 900 in the filter chamber 411, the filter material 900 will present different external manifestations under different working conditions. When the tank body 4101 and the spoiler 412 are set to transparent materials, it is convenient for the operator to check the working status of the filter material 900, so as to replace the failed filter material 900 in time.

[0085] It is understandable that the material setting form of the tank body 4101 and the spoiler 412 is not limited to the above one, as long as it can enable the operator to visualize the working status of the filter material 900 inside the processing tank 410, which will not be elaborated here.

[0086] In a preferred embodiment, Figures 1 to 5 As shown, the installation box includes a mounting frame 120 and a housing 110 fixedly disposed on the mounting frame 120 .

[0087] Among them, a accommodating cavity is provided in the outer shell 110, the display panel 220, the weather sensing unit 310, and the drying adsorption component 400 are fixedly arranged on the outer surface of the outer shell 110, and the humidity sensing unit 320, the washing and mixing unit 600, the vacuum suction unit 700, and the flow metering unit 330 are arranged in the accommodating cavity.

[0088] In a preferred embodiment, universal wheels are fixedly provided at the bottom of the installation frame 120, and the installation box can be moved as a whole through the universal wheels to adapt to different sampling environments and requirements.

[0089] The embodiment of the present application also provides a waste gas treatment method, which is applicable to the above-mentioned waste gas treatment equipment, including:

[0090] Step S1, obtaining weather status information within a predetermined time;

[0091] Step S2, when the weather status information meets the standard, the exhaust gas treatment equipment is controlled to be turned on and perform exhaust gas treatment, and when the weather status information does not meet the standard, the exhaust gas treatment equipment is controlled to remain closed;

[0092] Step S3: When the exhaust gas treatment equipment is turned on, the instantaneous flow information, cumulative flow information, sampling time and humidity information of the sampled exhaust gas are obtained and recorded.

[0093] In an embodiment of the present application, the above-mentioned exhaust gas treatment method is adopted, the predetermined time is used as the first trigger condition, and the weather status information obtained in real time is used as the second trigger condition. The working state of the exhaust gas treatment equipment is controlled by the comprehensive judgment of the two trigger conditions, and energy consumption optimization is achieved based on actual needs, thereby reducing energy consumption and carbon emissions during the operation of the exhaust gas treatment equipment, meeting the requirements of energy conservation and environmental protection. At the same time, various exhaust gas data are recorded and collected when the exhaust gas treatment equipment is working, which facilitates data tracing and intelligent management of exhaust gas treatment.

[0094] In a preferred embodiment, step S3 further includes:

[0095] Calculate and record the cumulative flow information based on the sampling time and instantaneous flow information.

[0096] In a preferred embodiment, step S3 further includes:

[0097] Step S4, forming a determination result based on the humidity information and the predetermined humidity threshold value comparison;

[0098] The specific determination results are as follows:

[0099] If the humidity information of the sampled exhaust gas meets the predetermined humidity threshold, the exhaust gas treatment device is kept turned on;

[0100] If the humidity information of the sampled exhaust gas does not meet the predetermined humidity threshold, the exhaust gas treatment equipment is controlled to switch to a closed state and an alarm is triggered.

[0101] In a preferred embodiment, step S3 further includes:

[0102] Outside the scheduled time, the exhaust gas treatment equipment is controlled to be in the closed state.
