[0002] Garbage disposal is an indispensable part of modern society. Garbage contains a variety of harmful substances. If not properly handled, it will pollute the soil, water and air, causing serious damage to the environment. However, various methods of garbage disposal will produce waste gas, and these waste gases require multi-step treatment methods to reduce the content and types of pollutants in them, ensure that they can meet national emission standards, and then be discharged into the external environment through waste gas pipes. In order to reduce the damage of this waste gas to the external environment, the most effective means is to conduct online monitoring of the waste gas discharged from the pipeline.

[0003] A patent document with publication number CN220563241U discloses an exhaust gas monitor, which facilitates the transportation and transfer of the monitor body by providing a box body and a box cover, and prevents the monitor body from shaking as the position of the box body changes during the transfer process by providing a supporting component and a clamping component.

[0016] A method for online monitoring of waste gas for garbage treatment, the method adopts the above-mentioned online monitoring system for waste gas for garbage treatment, and comprises the following steps:

[0017] Step 1: Monitoring preparation: carry the monitoring system and the device body to the monitoring site, place the sampling tube into the exhaust gas release pipe generated by garbage disposal, and cover the top cover of the device above the pipe;

[0018] Step 2: Determine the location: The sampling cylinder is initially placed at the top of the exhaust pipe.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The online waste gas monitoring system and method for garbage disposal described in the present invention covers the top of the waste gas pipe through the top cover of the device, and multiple sensors in the sensor array detect the content and type of waste gas pollutants at the top of the pipe at this time. However, the waste gas at the top of the pipe has already had a certain contact with the outside air, which will reduce the concentration of the waste gas. Therefore, in this device, the waste gas monitoring component can be moved to a deeper position in the pipe through the lifting module to monitor higher concentration waste gas, and the position of the waste gas monitoring component can be adjusted secondary inside the sampling tube through the sampling adjustment module, so that the waste gas monitoring component can also be adjusted in height inside the sampling tube, and the position of the waste gas monitoring component inside the pipe is more accurate.

[0025] 2. The present invention describes an online monitoring system and method for waste gas for garbage disposal. By making the diameter of the top cover of the device larger than the diameter of the sampling cylinder, when the top cover of the device covers the top of the waste gas pipe, the waste gas can be discharged through the top hollow mesh. When it is necessary to adjust the depth of the sampling cylinder inside the pipe, the winding wheel is driven by a fixed motor to rotate, and the lifting rope is unwound, so that the sampling cylinder and the sampling adjustment module descend inside the waste gas pipe due to gravity and move to the depth of the waste gas pipe. Generally speaking, the waste gas emission pipe for garbage disposal is cylindrical. When the sampling cylinder descends inside the pipe, it will protect the waste gas monitoring components inside it to prevent the more sophisticated sensor array, data processing module and alarm module from being damaged by external impact.

[0026] 3. The present invention describes an online monitoring system and method for waste gas for garbage disposal. By providing a spacing between the frame plate and the inner wall of the sampling tube, the waste gas inside the pipeline can be discharged through the spacing, the circular groove and the top hollow mesh, thereby avoiding the system and the device body affecting the waste gas emission of the pipeline itself when the system and the device body are online monitoring inside the pipeline. When the position of the sampling mechanism inside the sampling tube is adjusted by the sampling adjustment module, the sampling mechanism will rise and fall inside the inner frame. In order to further stabilize the position of the sampling mechanism, the displacement limit bar can be pushed to move by an electric structure such as a telescopic rod, so that the displacement limit bar is inserted into the limit bar groove of the corresponding height, thereby fixing the position of the sampling mechanism.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] Embodiment 1

[0040] like Figure 1-Figure 4 and Figure 8As shown, an online monitoring system for waste gas for garbage treatment according to an embodiment of the present invention comprises a sampling cylinder 1 placed in a waste gas pipe, a device top cover 2 is installed above the sampling cylinder 1, the device top cover 2 is installed above the waste gas pipe, the waste gas pipe is used to release waste gas after garbage treatment, a waste gas monitoring component 3 is movably installed inside the sampling cylinder 1, a sampling adjustment module 5 is installed inside the sampling cylinder 1, the sampling adjustment module 5 is used to adjust the height of the waste gas monitoring component 3, a lifting module 4 is installed between the sampling cylinder 1 and the device top cover 2, and the lifting module 4 is used to adjust the height of the sampling cylinder 1 in the waste gas pipe;

[0041] The exhaust gas monitoring component 3 includes a sampling mechanism 6 movably installed inside the sampling tube 1, and an exhaust gas monitoring module 7 is installed on the sampling mechanism 6. The exhaust gas monitoring module 7 includes a sensor array 71 installed on the sampling mechanism 6, a data processing module 72 and an alarm module 73. The sensor array 71 is a component composed of a plurality of sensors for monitoring pollutants in the exhaust gas.

[0042] Specifically, the system includes an external information terminal and an online monitoring system. The information terminal can be a mobile phone or a computer. The online monitoring system is connected to the mobile phone or the computer through the network. The waste gas generated by garbage disposal is discharged through a pipeline after multiple treatments. In order to minimize the impact of the discharged waste gas on the surrounding environment and staff, the pipeline will be elevated. By using a longer pipeline, the waste gas will be discharged to a higher position. In order to monitor whether the waste gas discharged from this pipeline meets the national emission standards, the sampling tube 1 is first placed in the waste gas pipeline. At this time, the top cover 2 of the device covers the top of the waste gas pipeline. The content and type of waste gas pollutants at the top of the pipeline can be detected by multiple sensors in the sensor array 71. However, the waste gas at the top of the pipeline has a certain contact with the outside air, which will reduce the concentration of the waste gas. Therefore, in this device, the waste gas monitoring component 3 can be moved to a deeper position in the pipeline through the lifting module 4 to monitor higher concentrations of waste gas, and the position of the waste gas monitoring component 3 can be adjusted by the sampling adjustment module 5 inside the sampling tube 1. A secondary adjustment is performed so that the height of the exhaust gas monitoring component 3 inside the sampling tube 1 can also be adjusted, which makes the exhaust gas monitoring component 3 more accurately positioned inside the pipeline. After multiple monitoring sensors 711 monitor multiple pollutants in the exhaust gas, the data processing module 72 receives the monitoring data of multiple monitoring sensors 711, analyzes the exhaust gas composition and its concentration changes, and determines whether it meets the emission standards. If it exceeds the standard, an alarm is issued through the alarm module 73. The alarm of the alarm module 73 can be displayed through the information terminal, and the final monitoring data can be transmitted to the information terminal. This device can perform online monitoring of different positions inside the pipeline to reduce the impact of the air content in the exhaust gas. When the pipeline releases exhaust gas all year round, the pollutants in the exhaust gas will adhere to the inner wall of the pipeline, and the deeper the pipeline, the more pollutants. When the exhaust gas is released, the pollutants in the pipeline may affect the quality of the exhaust gas release, and the exhaust gas release of the pipeline can be closed. The device is used to perform online monitoring at different positions in the pipeline to monitor whether there are pollutants exceeding the standard inside the pipeline when there is no exhaust gas.

[0043] like Figure 2 As shown, a plurality of component grooves 22 are opened through the top cover 2 of the device, a top hollow net 21 is fixedly installed at the inner center position of the top cover 2 of the device, the center of the top hollow net 21 and the center of the exhaust gas pipe are on the same vertical line, the lifting module 4 includes a winding wheel 41 movably installed inside the component groove 22, the end of the winding wheel 41 is connected to a fixed motor 42 through an axis, the fixed motor 42 is installed on the top cover 2 of the device, the winding wheel 41 winds up a lifting rope 43, the lifting module 4 also includes a lock 44 fixedly installed on the sampling tube 1, and the lower end of the lifting rope 43 is hooked with the lock 44.

[0044] Specifically, the diameter of the device top cover 2 is larger than the diameter of the sampling tube 1. When the device top cover 2 covers the top of the exhaust gas pipe, the exhaust gas can be discharged through the top hollow net 21. When the depth of the sampling tube 1 in the pipe needs to be adjusted, the winding wheel 41 is driven to rotate by the fixed motor 42, and the lifting rope 43 is unwound, so that the sampling tube 1 and the sampling adjustment module 5 descend inside the exhaust gas pipe due to gravity and move to the depth of the exhaust gas pipe. Generally speaking, the waste gas emission pipe of garbage disposal is cylindrical. When the sampling tube 1 descends inside the pipe, it will protect the exhaust gas monitoring component 3 inside it to prevent the more precise sensor array 71, data processing module 72 and alarm module 73 from being damaged by external impact.

[0045] like Figure 3 As shown, the sampling adjustment module 5 includes a plurality of upper fixed blocks 51 fixedly mounted on the top of the sampling tube 1 and a plurality of lower fixed blocks 53 fixedly mounted on the bottom of the sampling tube 1. A screw 52 is movably mounted between the upper fixed blocks 51 and the corresponding lower fixed blocks 53. A motor is mounted inside the upper fixed block 51 to drive the rotation of the screw 52. The sampling mechanism 6 is raised and lowered by the rotation of the plurality of screws 52.

[0046] Specifically, the sampling mechanism 6 is raised and lowered by the rotation of multiple screws 52. When the sampling tube 1 is raised and lowered inside the exhaust gas pipe, the position of the exhaust gas monitoring component 3 has been preliminarily adjusted. When the position of the exhaust gas monitoring component 3 needs to be adjusted for the second time, the upper fixed block 51 can be driven by the internal motor to make the multiple screws 52 rotate at the same time, thereby driving the sampling mechanism 6 and the exhaust gas monitoring module 7 to rise and fall inside the sampling tube 1, and further allowing the exhaust gas monitoring module 7 to monitor the exhaust gas pipe online at a deeper level.

[0047] like Figure 5-Figure 8 As shown, an inner frame 8 is fixedly installed inside the sampling tube 1, and the inner frame 8 includes four arc plates 82 fixedly connected to the inner wall of the sampling tube 1, a frame plate 81 is fixedly installed between two adjacent arc plates 82, and an inner triangular plate 83 is fixedly installed inside the frame plate 81, and a plurality of limiting grooves 84 are opened inside the inner triangular plate 83.

[0048] A plurality of spiral grooves 62 are fixedly installed inside the sampling mechanism 6, and the plurality of spiral grooves 62 are spirally connected to the corresponding plurality of screw rods 52. A plurality of triangular grooves 63 are provided on the outside of the sampling mechanism 6, and a strip groove 64 is provided inside the triangular groove 63. A displacement limiting strip 65 is movably installed inside the strip groove 64. A penetrating circular groove 61 is provided inside the sampling mechanism 6, and the end of the displacement limiting strip 65 is set to be pointed.

[0049] Specifically, there is a distance between the frame plate 81 and the inner wall of the sampling tube 1, and the exhaust gas inside the pipeline can be discharged through this distance, through the circular groove 61 and the top hollow mesh 21, so as to avoid the system and the device body affecting the exhaust gas emission of the pipeline itself when the system and the device body are online monitoring inside the pipeline. When the position of the sampling mechanism 6 inside the sampling tube 1 is adjusted by the sampling adjustment module 5, the sampling mechanism 6 will rise and fall inside the inner frame 8. In order to further stabilize the position of the sampling mechanism 6, the displacement limit bar 65 can be pushed to move by an electric structure such as a telescopic rod, so that the displacement limit bar 65 is inserted into the limit bar groove 84 of the corresponding height, thereby fixing the position of the sampling mechanism 6.

[0050] Embodiment 2

[0051] like Figure 8-Figure 9 As shown, compared with Example 1, another implementation of the present invention is: a plurality of support columns 68 are fixedly installed inside the through-circular groove 61, a suspended motor 67 is fixedly installed at one end of the plurality of support columns 68, the lower end of the suspended motor 67 is connected to a sampling fan 66 through an axis, the sampling fan 66 is located directly below the through-circular groove 61, the sensor array 71 includes a plurality of monitoring sensors 711, the plurality of monitoring sensors 711 are used to monitor the content and composition of various pollutants in the exhaust gas, monitoring probes 712 are installed on the sides of the monitoring sensors 711, and the plurality of monitoring probes 712 are staggered and all are located directly above the through-circular groove 61.

[0052] Specifically, in order to further increase the exhaust gas concentration, the sampling fan 66 can be driven to rotate by the suspended motor 67 to collect the smoke. The exhaust gas below the sampling fan 66 is collected into the through circular groove 61 for discharge under the action of suction. At this time, the exhaust gas concentration released from the through circular groove 61 is relatively high. The pollutants in the exhaust gas are monitored by the monitoring probes 712 of the multiple monitoring sensors 711. The number of the multiple monitoring sensors 711 can be multiple, such as CO2 sensors, Cairsens micro sensors and SPEC Sensors gas sensors, etc. These sensors can monitor various pollutants in the exhaust gas in a targeted manner.

[0053] A method for online monitoring of waste gas for garbage treatment, the method adopts the above-mentioned online monitoring system for waste gas for garbage treatment, and comprises the following steps:

[0054] Step 1: Monitoring preparation: carry the monitoring system and the device body to the monitoring site, place the sampling tube 1 into the exhaust gas release pipe generated by garbage disposal, and cover the top cover 2 of the device above the pipe;

[0055] Step 2: Determine the position: The sampling tube 1 is initially placed at the top of the exhaust pipe, and the fixed motor 42 drives the reel 41 to unwind the lifting rope 43, and the sampling tube 1 and the exhaust gas monitoring component 3 are lowered into the deep of the exhaust pipe. At this time, the high-concentration exhaust gas in the deep of the exhaust pipe will pass through the circular groove 61;

[0056] Step 3: Online monitoring: The suspended motor 67 drives the sampling fan 66 to rotate, and the exhaust gas below is concentrated above the through circular groove 61. At this time, the monitoring probes 712 outside the multiple monitoring sensors 711 are used to monitor the various pollutants in the exhaust gas online;

[0057] Step 4: Segmented sampling; the lifting module 4 can adjust the height of the sampling tube 1 and the exhaust gas monitoring component 3, and the rotation of the screw 52 can drive the exhaust gas monitoring component 3 to rise and fall inside the sampling tube 1, further accurately position the exhaust gas monitoring component 3 in the exhaust gas pipeline, and perform online monitoring of different positions inside the pipeline;

[0058] Step 5: Monitoring results; After multiple monitoring sensors 711 monitor multiple pollutants in the exhaust gas, the data processing module 72 receives the monitoring data of the multiple monitoring sensors 711, analyzes the exhaust gas composition and its concentration changes, and determines whether it meets the emission standards. If it exceeds the standard, an alarm is issued through the alarm module 73.

[0059] The sensor array 71, the data processing module 72 and the alarm module 73 are connected to the external information terminal through the network. The information terminal is preferably a computer and a mobile phone. The alarm information of the alarm module 73 is sent to the information terminal through the network. The alarm of the alarm module 73 also emits a sound alarm through a buzzer alarm.

[0060] Working principle: This system includes an external information terminal and an online monitoring system. The information terminal can be a mobile phone or a computer. The online monitoring system is connected to the mobile phone or the computer through the network. The waste gas generated by garbage disposal is discharged through a pipeline after multiple treatments. In order to minimize the impact of the discharged waste gas on the surrounding environment and staff, the pipeline will be elevated. By using a longer pipeline, the waste gas will be discharged to a higher position. In order to monitor whether the waste gas discharged from this pipeline meets the national emission standards, the sampling tube 1 is first placed in the waste gas pipeline. At this time, the top cover 2 of the device covers the top of the waste gas pipeline. The multiple sensors in the sensor array 71 can be used to detect the content and type of waste gas pollutants at the top of the pipeline at this time. However, the waste gas at the top of the pipeline has a certain contact with the outside air, which will reduce the concentration of the waste gas. Therefore, in this device, the waste gas monitoring component 3 can be moved to a deeper position in the pipeline through the lifting module 4 to monitor higher concentrations of waste gas, and the position of the waste gas monitoring component 3 can be adjusted inside the sampling tube 1 through the sampling adjustment module 5. A secondary adjustment is performed so that the height of the exhaust gas monitoring component 3 inside the sampling tube 1 can also be adjusted, which makes the exhaust gas monitoring component 3 more accurately positioned inside the pipeline. After multiple monitoring sensors 711 monitor multiple pollutants in the exhaust gas, the data processing module 72 receives the monitoring data of multiple monitoring sensors 711, analyzes the exhaust gas composition and its concentration changes, and determines whether it meets the emission standards. If it exceeds the standard, an alarm is issued through the alarm module 73. The alarm of the alarm module 73 can be displayed through the information terminal, and the final monitoring data can be transmitted to the information terminal. This device can perform online monitoring of different positions inside the pipeline to reduce the impact of the air content in the exhaust gas. When the pipeline releases exhaust gas all year round, the pollutants in the exhaust gas will adhere to the inner wall of the pipeline, and the deeper the pipeline, the more pollutants. When the exhaust gas is released, the pollutants in the pipeline may affect the quality of the exhaust gas release, and the exhaust gas release of the pipeline can be closed. The device is used to perform online monitoring at different positions in the pipeline to monitor whether there are pollutants exceeding the standard inside the pipeline when there is no exhaust gas.
