Description

Technical Field

[0002] Most of the pollution sources that cause serious air pollution are in fixed locations or cannot move, such as flues, workshops, etc. These pollution sources are called fixed pollution sources. There are strict standard indicators for the exhaust gas emissions generated by fixed pollution sources. Before the exhaust gas is discharged, it must be monitored to meet the relevant indicators. Only qualified and treated and purified gases can be discharged into the air.

[0003] At present, in the equipment for detecting low-concentration particulate matter, the Beta ray detection method uses the principle of Beta ray attenuation. The ambient air is sucked into the sampling tube by the sampling pump and discharged after passing through the filter membrane. The particulate matter is deposited on the filter membrane. When the beta ray passes through the filter membrane where the particulate matter is deposited, the energy of the Beta ray decays. The concentration of the particulate matter can be calculated by measuring the attenuation amount. When using this Beta ray detection method to detect atmospheric particulate matter, the filter membrane needs to be replaced after each detection. However, the existing equipment of this type is relatively cumbersome when replacing the filter membrane, the membrane replacement mechanism is complex, and the filter membrane is easily damaged during the membrane replacement process.

[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0033] An ecological environment fixed pollution source atmosphere detection device in the present embodiment relates to the field of environmental monitoring technology. By installing the filter membrane 110 flatly in the filter membrane carrier 100 and adopting a box-type slide 210, the filter membrane carrier 100 can be fed in sequence and different filter membranes 110 can be used in turn without manual replacement of the filter membrane 110, thereby achieving long-term standby use of the detection device.

[0034] See also Figures 1 to 8 In this embodiment, an ecological environment fixed pollution source air monitoring device includes: a filter membrane carrier 100, a sliding component 200 and a suction component 300. The filter membrane carrier 100 is detachably connected to the filter membrane 110, and the filter membrane 110 can be pre-installed on the filter membrane carrier 100, so that the filter membrane 110 is relatively flat and wrinkle-free, which is convenient for the use of the filter membrane 110.

[0035] The sliding assembly 200 includes a vertically arranged slideway 210 and a transport unit 220. A plurality of filter membrane carriers 100 are slidably inserted into the slideway 210. The upper and lower parts of each filter membrane carrier 100 are abutted, and a plurality of workstations adapted to the filter membrane carriers 100 are formed on the slideway 210. Each filter membrane carrier 100 can be switched to an adjacent workstation as the filter membrane carrier 100 moves. The transport unit 220 can push out the filter membrane carrier 100 located at the bottom, so that the filter membrane carrier 100 is fed along the workstation. Each filter membrane carrier 100 is fed by the length of a filter membrane carrier 100 at a time, and the purpose of suction filtration and detection is completed at different workstations.

[0036] The suction assembly 300 includes a suction tube 310 and a movable abutment tube 320 arranged relative to a work station. The suction tube 310 is fixedly connected to the slide 210 and is communicated with the interior of the slide 210. The abutment tube 320 can impact the filter membrane carrier 100, so that the two ends of the filter membrane carrier 100 are respectively docked with the suction tube 310 and the abutment tube 320. The suction tube 310 can drive the atmosphere to pass through the abutment tube 320 and the filter membrane carrier 100 in turn, and the filter membrane 110 on the filter membrane carrier 100 can separate particulate matter in the atmosphere.

[0037] During use, the filter membrane carrier 100 is installed in the slide 210 in sequence. The filter membrane carrier 100 can move downward under the action of gravity. The transport unit 220 can put down the filter membrane carrier 100 one by one, so that the filter membrane carrier 100 can move on different stations. At one of the stations, the abutment tube 320 hits the filter membrane carrier 100, so that the two sides of the filter membrane carrier 100 are respectively connected to the abutment tube 320 and the suction tube 310 and relatively sealed. The negative pressure of air in the atmosphere passes through the filter membrane 110, which can separate the particles in the atmosphere. The transport unit 220 is started, so that all the filter membrane carriers 100 move down the distance of one station, the used filter membrane carrier 100 is separated from the abutment tube 320, and the unused filter membrane carrier 100 is re-adapted to the abutment tube 320. There is no need to manually replace the filter membrane 110, and the next detection is automatically carried out, which can realize all-weather automatic detection.

[0038] In some embodiments, see Figures 2 to 6 A first sealing unit 330 is provided between the suction tube 310 and the filter membrane carrier 100. The first sealing unit 330 includes a truncated cone 331 provided on the filter membrane carrier 100, and the truncated cone 331 is plugged into the end of the abutting tube 320. The truncated cone 331 of the first sealing unit 330 is plugged into the end of the abutting tube 320, forming a sealed connection. During the detection process, when the atmosphere flows through the filter membrane carrier 100 through the suction tube 310, it can ensure that the connection between the suction tube 310 and the filter membrane carrier 100 is completely sealed, preventing atmospheric leakage or external pollutants from entering the detection system, thereby ensuring the accuracy and reliability of the detection results.

[0039] As a further implementation, see Figure 2 and Figure 3The end of the abutting tube 320 is gradually expanded from the inside to the outside to form a speaker cavity 321. The table surface of the truncated cone 331 abuts against the inner wall of the speaker cavity 321. The speaker cavity 321 is provided with a first sealing ring 322 for abutting against the truncated cone 331. The setting of the speaker cavity 321 makes the end of the abutting tube 320 present a gradually expanding structure, which can increase the sealing area and improve the sealing performance. When the truncated cone 331 abuts against the inner wall of the speaker cavity 321, the sealing ring can fully fit the truncated cone 331 and the speaker cavity 321 to form a tighter sealing structure, effectively preventing atmospheric leakage and the entry of external pollutants.

[0040] In the specific implementation process, at least two sealing rings are provided and are equidistant from each other. The sealing rings are made of flexible rubber material. The sealing rings can effectively prevent gas leakage and ensure the flow pressure of the gas.

[0041] In some embodiments, see Figure 7 A second sealing unit 340 is provided between the slideway 210 and the filter membrane carrier 100. The second sealing unit 340 includes a sealing groove 341 and a second sealing ring provided on the slideway 210. The second sealing ring is embedded in the sealing groove 341, and the end of the filter membrane carrier 100 abuts against the sealing ring. The provision of the sealing groove 341 and the sealing ring of the second sealing unit 340 increases the contact area between the filter membrane carrier 100 and the slideway 210, and improves the stability of the connection. The sealing ring is embedded in the sealing groove 341, which can effectively fix the filter membrane carrier 100, prevent it from moving or swinging during the detection process, and ensure the accuracy and reliability of the detection results.

[0042] A second sealing unit 340 is provided between the slideway 210 and the filter membrane carrier 100 . The second sealing unit 340 includes a sealing groove 341 opened on the slideway 210 and a second sealing ring. The second sealing ring is made of flexible rubber and is embedded in the sealing groove 341 .

[0043] When the filter membrane carrier 100 is inserted into the slideway 210, the end of the filter membrane carrier 100 abuts against the second sealing ring, and the sealing ring is embedded in the sealing groove 341, forming a sealed connection structure. This can prevent the atmosphere from leaking through the gap between the filter membrane carrier 100 and the slideway 210, ensuring that the atmosphere flows completely through the filter membrane carrier 100, thereby ensuring the accuracy and reliability of the detection results.

[0044] In some embodiments, see Figure 1 and Figure 8 The transport unit 220 includes a rotatable turntable 221, which is rotatably connected to the slideway 210. The turntable 221 can push out the filter membrane carriers 100 one by one.

[0045] An arc portion adapted to the filter membrane carrier 100 is provided on the edge of the turntable 221, and the arc portion can abut and cooperate with the edge of the filter membrane carrier 100. N arc portions are equidistantly arranged around the central axis of the turntable 221. The disk is rotatably connected to the servo motor. Each time the disk rotates 2π / N rad, the filter membrane carriers 100 can be pushed out of the slide 210 one by one, thereby simplifying the operating steps of replacing the filter membrane 110.

[0046] At the same time, pushing out the filter membrane carriers 100 one by one also helps to avoid mutual interference between the filter membrane carriers 100, ensuring the smooth progress of the replacement process.

[0047] As an alternative technical solution, the transport component can also be a limit block that is retractable relative to the inner side of the slide 210. The limit block is driven by a pneumatic cylinder, a hydraulic cylinder or an electric push rod, so that the limit block can be intermittently inserted into the slide 210 to hinder the movement of the filter membrane carrier 100. By accurately controlling the interval between the withdrawal and reinsertion of the limit block, it is possible to ensure that the filter membrane carriers 100 are pushed out one by one to achieve the same purpose.

[0048] In some embodiments, see Figure 4 The filter membrane carrier 100 includes a clamping body 120 and a fixing ring 130. The clamping body 120 is provided with a mounting hole for mounting the filter membrane 110. The fixing ring 130 is arranged to surround the filter membrane 110, and the fixing ring 130 is connected to the clamping body 120 by bolts. The fixing ring 130 is connected to the clamping body 120 by bolts, which can ensure that the filter membrane 110 is fixed firmly. The bolt connection forms a firm connection between the fixing ring 130 and the clamping body 120, avoiding the displacement or falling off of the filter membrane 110 due to looseness or shaking, and can ensure the stability and reliability of the filter membrane 110 during use.

[0049] In addition, the fixing ring 130 tightly clamps the outer edge of the filter membrane 110, and can tighten the filter membrane 110 from the outside to the inside, so that the filter membrane 110 always remains in a straight state, which is beneficial to the filtering and separation of particulate matter in the atmosphere.

[0050] In some embodiments, see Figure 1 and Figure 7 An ecological environment fixed pollution source atmosphere monitoring device also includes a loading component 400, the loading component 400 includes a loading cylinder 410 and an elastic member, a plurality of filter membrane carriers 100 are loaded in the loading cylinder 410, the elastic member is arranged in the loading cylinder 410, and the elastic member can push the filter membrane carriers 100 stored in the loading cylinder 410 into the slide 210 in sequence, replenishing the filter membrane carriers 100 for the slide 210, and further extending the service life of the device.

[0051] As a part of the loading assembly 400, the loading cylinder 410 can accommodate multiple filter membrane carriers 100. Multiple filter membrane carriers 100 are loaded into the loading cylinder 410 at one time, thereby simplifying the loading process of the filter membrane carriers 100. The filter membrane carriers 100 are stacked on each other in the thickness direction, which can maximize the use of space, increase the loading capacity of the filter membrane carriers 100, and further extend the use time of the device.

[0052] In addition, when the filter membrane carrier 100 is loaded in the loading cylinder 410, the elastic member can provide a certain degree of pressure and support to prevent the filter membrane carrier 100 from being damaged by external impact. This helps to extend the service life of the filter membrane carrier 100 and reduce the possibility of damage to the filter membrane carrier 100 during transportation or operation.

[0053] In some embodiments, an ecological environment fixed pollution source atmosphere detection device further includes a detection component, the detection component includes a beta ray detector and a bracket, the beta ray detector is connected to the slide 210 through the bracket, the beta ray detector is set relative to a station of the slide 210, and the station relative to the beta ray detector is set at an interval with the station relative to the impact tube, thereby avoiding mutual interference between the two components. When the filter membrane carrier 100 passes through the detection station, it can ensure that there is no collision or cross interference between the beta ray detector and the impact tube, thereby ensuring the normal operation of the equipment and the accuracy of the detection results.

[0054] In addition, the positions of the β-ray detector and the impact tube are arranged reasonably, so that the space of the entire detection system is fully utilized. By setting appropriate intervals, the reasonable layout of each component is ensured, and it is also convenient for operators to maintain and adjust the equipment.

[0055] In some embodiments, see Figure 1 and Figure 2 A driving assembly is provided between the impact tube and the slideway 210, and the driving assembly includes a fixed ring 130, a sliding ring, a bracket and a linear driving member. The fixed ring 130 is sleeved on the impact tube and fixedly connected to the impact tube, and the sliding ring is connected to the slideway 210 through the bracket. The impact tube and the sliding ring are slidably plugged, and a plurality of linear driving members are provided between the sliding ring and the fixed ring 130, and the two ends of the linear driving member are respectively connected to the sliding ring and the fixed ring 130. The linear driving member is a cylinder, a hydraulic cylinder or an electric push rod, which can push the impact tube to move relative to the filter membrane carrier 100 located at a specific station to achieve the connection and sealing of the filter membrane carrier 100.

[0056] Workflow: First, fill the loading cylinder 410 with the filter membrane carrier 100, and clamp the filter membrane carrier 100 in the slideway 210 in turn. Then, the impact tube moves relative to the filter membrane carrier 100 located in the corresponding station, and the two ends of the filter membrane carrier 100 are respectively docked with the suction tube 310 and the abutment tube 320. The suction tube 310 can drive the atmosphere to pass through the abutment tube 320 and the filter membrane carrier 100 in turn. The filter membrane 110 on the filter membrane carrier 100 can separate the particulate matter in the atmosphere. The impact tube is away from the used filter membrane carrier 100. Next, the turntable 221 drives the filter membrane carrier 100 to feed a station, and the filter membrane carrier 100 with retained particulate matter is set relative to the β-ray detector to obtain a test result. The new filter membrane carrier 100 is pushed out of the loading cylinder 410, and the new filter membrane carrier 100 cooperates with the impact tube. After waiting for a few hours, the above cycle is repeated to achieve uninterrupted automatic testing of the atmosphere.

[0057] The above description is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the present invention.
