Description

Technical Field

[0001] This utility model relates to the field of flue gas monitoring technology for desulfurization and dust removal, specifically to an online monitoring device for flue gas used in desulfurization and dust removal. Background Technology

[0002] Online monitoring equipment for desulfurization and dust removal mainly consists of online emission monitoring systems (CEMS). CEMS is an important device used to monitor the concentration of pollutants in flue gas emitted during industrial production processes in real time. It is widely used in industrial sites such as coal-fired power plants, chemical plants, and steel mills to monitor the emissions of harmful gases such as sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM) generated during combustion, ensuring that emissions comply with environmental regulations and standards.

[0003] A search revealed a Chinese patent with authorization number CN216525331U, which discloses an online monitoring device for flue gas used in desulfurization and dust removal. The device uses a flue gas collector, a pull rope, a hook, and a winding roller to control the raising and lowering of the flue gas collector, thereby collecting flue gas floating at different heights, improving the collection of flue gas and obtaining more accurate values.

[0004] The above-mentioned patent has the following shortcomings in the online monitoring device for flue gas used for desulfurization and dust removal: when collecting flue gas through the flue gas collector, the hook needs to be installed on the top of the wall first, and then the flue gas collector needs to be fixed and installed with the pull rope and fixing ring. Because the hook is fixed, the position of the flue gas collector is fixed and it cannot be collected in other locations. Moreover, it can only be installed through the hook, which has certain limitations and is inconvenient to use. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an online monitoring device for flue gas used in desulfurization and dust removal, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an online monitoring device for flue gas used in desulfurization and dust removal, comprising a base, a monitoring device body fixedly mounted on the upper surface of the base, a threaded sleeve movably connected to the upper surface of the base on one side of the monitoring device body, a threaded rod threadedly fitted onto the inner wall of the threaded sleeve, an electric telescopic rod fixedly mounted on the inner wall of the threaded rod, a fixing plate fixedly connected to the top of the electric telescopic rod, a mounting seat fixedly connected to the lower surface of the fixing plate away from the electric telescopic rod, an mounting groove formed on the surface of the mounting seat, a mounting block movably fitted onto the inner wall of the mounting groove, a mounting frame fixedly connected to the bottom of the mounting block, a fixing block fixedly connected to the upper surface of the inner wall of the mounting frame, a flue gas collector movably mounted on the upper surface of the fixing block, and a connecting pipe fixedly connected to the top of the monitoring device body movably connected to the top of the flue gas collector.

[0007] By adopting the above technical solution, the threaded sleeve can drive the threaded rod to rise and fall, the threaded rod can drive the electric telescopic rod to rise and fall, and the electric telescopic rod can drive the fixed plate to rise and fall, thereby adjusting the height of the flue gas collector. The flue gas collected by the flue gas collector can be transmitted to the main body of the monitoring equipment for detection through the connecting pipe, thus facilitating the collection and detection of flue gas at different heights.

[0008] Secondly, by inserting the mounting block on the mounting bracket into the inner wall of the mounting groove on the mounting base, the flue gas collector on the mounting bracket can be installed and used. At the same time, the flue gas collector can be movably installed on the connecting bracket by the fixing block. The operation is simple and convenient, and the flue gas collector can be easily disassembled, making it easier to clean and use, which improves the detection effect to a certain extent.

[0009] Furthermore, an L-shaped mounting plate is fixedly connected to the upper surface of one end of the base, and a motor is fixedly mounted on the lower surface of the L-shaped mounting plate. The output end of the motor is connected to a first gear that is movably connected to the upper surface of the base via a coupling, and a second gear that meshes with the first gear is fixedly sleeved on the outer wall of the bottom end of the threaded sleeve.

[0010] By adopting the above technical solution, the motor drives the first gear to rotate, and the first gear, in conjunction with the second gear, drives the threaded sleeve to rotate, thereby facilitating the lifting and lowering of the threaded rod.

[0011] Furthermore, a limiting block is fixedly sleeved on the outer wall of the threaded rod, and a dovetail groove is provided at one end of the limiting block. A dovetail block matching the dovetail groove is fixedly connected to one side surface of the main body of the monitoring device.

[0012] By adopting the above technical solution, the dovetail groove and dovetail block on the limiting block facilitate the limiting use of the threaded rod, thereby driving the threaded rod to rise and fall.

[0013] Furthermore, a connecting plate is fixedly connected to the lower surface of one end of the fixing plate, and a plug extending to the inner wall of the mounting groove is movably sleeved on the surface of the connecting plate. A through hole matching the plug is opened on the surface of the mounting block.

[0014] By adopting the above technical solution, the mounting bracket and the fixing plate can be easily fixedly connected by inserting the plug rod into the inner wall of the through hole on the mounting block.

[0015] Furthermore, a handle is fixedly connected to one end of the insertion rod on the side of the connecting plate away from the mounting base, and a spring is fixedly sleeved on the outer wall of the insertion rod between the connecting plate and the mounting base, with one end of the spring fixedly connected to the connecting plate.

[0016] By adopting the above technical solution, the plug rod can be moved and used by pulling the handle, and the plug rod can be reset by the elastic force of the spring.

[0017] Furthermore, the surface of the fixing block is provided with a positioning groove, and the inner wall of the positioning groove is symmetrically provided with two sets of slots. The bottom end of the flue gas collector is fixedly connected with a positioning block that matches the positioning groove, and the outer wall of the positioning block is symmetrically fixedly connected with a slot that matches the slot.

[0018] By adopting the above technical solution, the positioning block on the flue gas collector is snapped into the inner wall of the positioning groove on the fixed block, and the snapping block and the slot are engaged. Then, the flue gas collector is rotated, and the flue gas collector is limited by the cooperation between the snapping block and the slot. Thus, the flue gas collector can be installed on the surface of the mounting frame to collect and use flue gas.

[0019] In summary, the present invention has the following advantages: By attaching the mounting block to the inner wall of the mounting groove and inserting the rod into the inner wall of the through hole on the mounting block, the flue gas collector on the mounting frame can be easily installed on the fixed plate. When the position of the flue gas collector needs to be adjusted, the position of the main body of the monitoring device can be moved to another position for testing. The overall adaptability is strong and the limitations are small. When the flue gas collector has been used for a long time, it can be removed from the mounting frame, which facilitates cleaning and use of the flue gas collector. The operation is simple, convenient and flexible. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] An online monitoring device for flue gas used in desulfurization and dust removal, such as Figures 1-7 As shown, it includes a base 1, and a monitoring device body 11 is fixedly installed on the upper surface of the base 1. The monitoring device body 11 is used to detect and analyze the flue gas.

[0031] For example, a threaded sleeve 2 is movably connected to the upper surface of the base 1 on one side of the main body 11 of the monitoring equipment. A threaded rod 22 is threadedly sleeved on the inner wall of the threaded sleeve 2. An electric telescopic rod 3 is fixedly installed on the inner wall of the threaded rod 22. A fixed plate 31 is fixedly connected to the top of the electric telescopic rod 3. The threaded sleeve 2 can drive the threaded rod 22 to rise and fall. The threaded rod 22 drives the electric telescopic rod 3 to rise and fall. The electric telescopic rod 3 can drive the fixed plate 31 to rise and fall. Thus, the height of the flue gas collector 7 can be adjusted, which facilitates the collection and detection of flue gas at different heights.

[0032] For example, a mounting base 32 is fixedly connected to the lower surface of the fixed plate 31 away from the electric telescopic rod 3. The surface of the mounting base 32 is provided with a mounting groove 33. A mounting block 41 is movably sleeved on the inner wall of the mounting groove 33. A mounting frame 4 is fixedly connected to the bottom end of the mounting block 41. By inserting the mounting block 41 on the mounting frame 4 into the inner wall of the mounting groove 33 on the mounting base 32, the flue gas collector 7 on the mounting frame 4 can be installed and used.

[0033] For example, a fixing block 6 is fixedly connected to the upper surface of the inner wall of the mounting frame 4, and a flue gas collector 7 is movably mounted on the upper surface of the fixing block 6. The flue gas collector 7 can be mounted on the surface of the mounting frame 4 through the fixing block 6 on the mounting frame 4.

[0034] For example, the top of the flue gas collector 7 is movably connected to a connecting pipe 73 that is fixedly connected to the top of the monitoring equipment body 11. The flue gas collected by the flue gas collector 7 can be transmitted to the inside of the monitoring equipment body 11 for detection through the connecting pipe 73.

[0035] In some examples, please refer to Figure 1 and Figure 2 An L-shaped mounting plate 12 is fixedly connected to the upper surface of one end of the base 1. A motor 13 is fixedly mounted on the lower surface of the L-shaped mounting plate 12. The output end of the motor 13 is connected to a first gear 14 that is movably connected to the upper surface of the base 1 via a coupling. A second gear 21 that meshes with the first gear 14 is fixedly sleeved on the outer wall of the bottom end of the threaded sleeve 2. The first gear 14 is driven to rotate by the motor 13, and the first gear 14, in conjunction with the second gear 21, drives the threaded sleeve 2 to rotate, thereby facilitating the lifting and lowering of the threaded rod 22.

[0036] In some examples, please refer to Figure 6 A limiting block 23 is fixedly sleeved on the outer wall of the threaded rod 22. One end of the limiting block 23 is provided with a dovetail groove 231. A dovetail block 111 that matches the dovetail groove 231 is fixedly connected to one side surface of the monitoring equipment body 11. The setting of the dovetail groove 231 and the dovetail block 111 on the limiting block 23 facilitates the use of limiting the threaded rod 22, thereby driving the threaded rod 22 to rise and fall.

[0037] In some examples, please refer to Figure 7 A connecting plate 34 is fixedly connected to the lower surface of one end of the fixing plate 31. A plug rod 5 extending to the inner wall of the mounting groove 33 is movably sleeved on the surface of the connecting plate 34. The plug rod 5 can be installed and used through the connecting plate 34.

[0038] For example, the surface of the mounting block 41 is provided with a through hole that matches the insertion rod 5. By inserting the insertion rod 5 into the inner wall of the through hole on the mounting block 41, it is easy to fix the mounting bracket 4 to the fixing plate 31.

[0039] In some examples, please refer to Figure 7 A handle 51 is fixedly connected to one end of the insertion rod 5 on the side of the connecting plate 34 away from the mounting base 32. A spring 52 is fixedly sleeved on the outer wall of the insertion rod 5 between the connecting plate 34 and the mounting base 32. One end of the spring 52 is fixedly connected to the connecting plate 34. The insertion rod 5 can be moved by the handle 51 and can be reset by the elastic force of the spring 52.

[0040] In some examples, please refer to Figure 4 and Figure 5 The surface of the fixing block 6 is provided with a positioning groove 61, and the inner wall of the positioning groove 61 is symmetrically provided with two sets of slots 62. The bottom end of the flue gas collector 7 is fixedly connected to a positioning block 71 that matches the positioning groove 61. The outer wall of the positioning block 71 is symmetrically fixedly connected to a locking block 72 that matches the slot 62. By locking the positioning block 71 on the flue gas collector 7 to the inner wall of the positioning groove 61 on the fixing block 6, and locking the locking block 72 to the slot 62, and then rotating the flue gas collector 7, the flue gas collector 7 is limited by the mutual cooperation of the locking block 72 and the slot 62, so that the flue gas collector 7 can be installed on the surface of the mounting frame 4 for collecting and using flue gas.

[0041] The working principle of this utility model is as follows: When the flue gas collector 7 needs to be used, the positioning block 71 on the flue gas collector 7 is inserted into the inner wall of the positioning groove 61, and then the flue gas collector 7 is rotated, so that the locking block 72 can be locked into the inner wall of the locking groove 62, thereby facilitating the installation and use of the flue gas collector 7.

[0042] Furthermore, after the flue gas collector 7 is installed on the mounting bracket 4, the mounting block 41 is snapped into the inner wall of the mounting groove 33, and the insertion rod 5 is inserted into the inner wall of the through hole on the mounting block 41 to fix the mounting bracket 4 and the fixing plate 31. The flue gas can then be collected and used through the flue gas collector 7, and then transmitted to the monitoring equipment body 11 for detection through the connecting pipe 73.

[0043] Furthermore, when it is necessary to detect smoke from a high place, the motor 13 drives the first gear 14 to rotate, the first gear 14 drives the second gear 21 to rotate, and the second gear 21 drives the threaded sleeve 2 to rotate. Through the cooperation of the limit block 23 and the dovetail block 111, the threaded rod 22 is moved. Then, the electric telescopic rod 3 is activated. The electric telescopic rod 3, together with the fixed plate 31, drives the smoke collector 7 to rise, so that the smoke from a high place can be collected and detected through the smoke collector 7. The operation is simple and convenient.
