Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas emission technology, and in particular to a monitoring device for industrial waste gas emissions. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead, mercury, beryllium compounds, soot, and industrial dust. When released into the atmosphere, they pollute the air. These substances enter the human body through the respiratory tract via various pathways; some cause direct harm, while others have a cumulative effect, further jeopardizing human health. Different substances have different effects. To strengthen environmental protection, it is necessary to monitor emitted waste gases.

[0003] Patent document CN217443288U discloses a detection device for industrial waste gas emissions, including a chimney. A base is fixedly installed at the bottom of the chimney, and a smoke exhaust port is fixedly installed at the top of the chimney. A lightning rod is fixedly installed at the top of the smoke exhaust port. A detection mechanism is installed on the chimney, and a cooling mechanism is installed on the detection mechanism. The detection mechanism detects the waste gas, a cooling water pipe cools the protective shell to protect the detector and extend its service life, a pressure pump applies pressure to the water, allowing the water level to rise to a specified height, a first valve and a water injection pipe fill the water tank, a fan cools the water on the inner wall of the water tank, a telescopic limit rod changes the direction of movement of the threaded sleeve, and a combination of a drain pipe and a second valve facilitates the discharge of cooled water.

[0004] Although the aforementioned technologies detect the exhaust gas, the gas has already been discharged when it is detected that the exhaust gas is substandard, thus lacking the function of blocking substandard exhaust gas. To address the above problems, we have introduced a monitoring device for industrial exhaust gas emissions. Summary of the Invention

[0005] This utility model discloses a monitoring device for industrial waste gas emissions, aiming to solve the technical problem in related technologies that, although the emitted waste gas is detected, the gas has already been emitted when the emitted waste gas is found to be substandard, thus lacking the function of blocking the substandard waste gas.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A monitoring device for industrial waste gas emissions includes a base, a chimney body, a monitoring component, a cooling component, and a baffle component. The chimney body is fixedly installed on the top of the base. The monitoring component is located on the side of the chimney body near the top. A flue gas outlet is fixedly installed on the top of the chimney body. A baffle component is located on the top of the flue gas outlet. A cooling component is located on one side of the chimney body. The baffle component includes a second motor. A lead screw is connected to the top side of the flue gas outlet via the second motor. A moving block is threaded to the outer side of the lead screw. A baffle is fixedly installed on one side of the moving block. Limiting rods are fixedly installed on the top of the flue gas outlet. The limiting rods all penetrate the baffles and are slidably connected to the baffles.

[0008] During operation, industrial waste gas is emitted through the main body of the chimney. The monitoring components periodically detect the waste gas flowing through the main body of the chimney. When the flue gas flowing inside the main body of the chimney does not meet the emission standards, the external controller activates the baffle assembly. The output of the No. 2 motor rotates, driving the lead screw to rotate, which in turn moves the moving block and the baffle down to completely block the exhaust port. This helps prevent the emission of non-compliant waste gas. This solves the problem in related technologies where, although the emitted waste gas is detected, the gas has already been discharged when non-compliant waste gas is detected, thus lacking the function of blocking non-compliant waste gas.

[0009] In a preferred embodiment, the monitoring component includes a fixed box, which is fixedly installed on the outside of the chimney body and near the top. The fixed box has an internal cavity that communicates with the inside of the chimney body. A rotating rod is rotatably connected inside the internal cavity. Four partitions are fixedly installed in a circumferential array on the outer side of the rotating rod. A monitoring chamber is opened on the side of the internal cavity away from the chimney body. A No. 1 motor is connected to the top of the fixed box near the rotating rod via a fixing frame. The output end of the No. 1 motor is fixedly connected to the rotating rod. A monitoring instrument body is connected to the top of the fixed box via an insulation shell. A detection probe is fixedly installed at the bottom of the monitoring instrument body and extends into the monitoring chamber.

[0010] By setting up a monitoring component, the output of motor No. 1 drives the rotating rod to rotate, which in turn drives the four baffles to make circular motion, continuously drawing the flue gas inside the chimney into the monitoring chamber. The monitoring instrument and detection probe then detect the flue gas. If the detection fails, the external control system can be activated to activate the baffle component to continue blocking the exhaust port, making the detection more convenient.

[0011] In a preferred embodiment, the cooling component includes a cold water tank and a water storage tank. An insulation cavity is formed inside the insulation shell. The top of the cold water tank is connected to a first connecting pipe via a pump body. The first connecting pipe extends into the insulation cavity from the side near the insulation shell. A second connecting pipe is fixedly installed through the insulation shell from the bottom side. The bottom end of the second connecting pipe extends into the water storage tank. An inlet pipe is fixedly installed through one side of the cold water tank, and a drain pipe is fixedly installed through one side of the water storage tank.

[0012] By setting up a cooling component, cold water is added to the cold water tank through the water inlet pipe connected to an external water source. Cold water is also injected into the insulation cavity through the pump body and the No. 1 connecting pipe to protect the main body of the monitoring instrument during use. The water storage tank facilitates the collection of water discharged from the No. 2 connecting pipe, thus saving water resources.

[0013] In a preferred embodiment, a support frame is fixedly installed between the bottom of the fixed box and the main body of the chimney.

[0014] Setting up a support frame helps to enhance the stability of the fixed box.

[0015] In a preferred embodiment, the inner cavity is configured as an arc-shaped structure, and the side of the partition closest to the inner cavity is in contact with and slidably connected to the inner cavity.

[0016] By designing a partition that fits into the inner cavity, it becomes more convenient to use.

[0017] In a preferred embodiment, a one-way valve is provided on the outside of the second connecting pipe, and valves are provided on the outside of both the inlet pipe and the outlet pipe.

[0018] The one-way valve installed on the outside of the No. 2 connecting pipe helps prevent backflow inside the No. 2 connecting pipe.

[0019] The monitoring device for industrial waste gas emissions provided by this utility model has the following advantages:

[0020] Firstly, during operation, industrial waste gas is emitted through the main body of the chimney. The monitoring components installed periodically detect the waste gas flowing through the main body of the chimney. When the flue gas flowing inside the main body of the chimney is detected to be non-compliant with emission standards, the external controller activates the baffle assembly. The output of motor No. 2 rotates the lead screw, which in turn moves the moving block and the baffle down to completely block the exhaust port. This helps prevent the emission of non-compliant waste gas. This solves the problem in related technologies where, although the emitted waste gas is detected, the gas has already been emitted when non-compliant waste gas is detected, thus lacking the function of blocking non-compliant waste gas.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A monitoring device for industrial waste gas emissions includes: a base 1, a chimney body 2, a monitoring component 3, a cooling component 4, and a baffle component 5. The chimney body 2 is fixedly installed on the top of the base 1. The monitoring component 3 is arranged on the side of the chimney body 2 near the top. A smoke outlet 21 is fixedly installed on the top of the chimney body 2. A baffle component 5 is arranged on the top of the smoke outlet 21. A cooling component 4 is arranged on one side of the chimney body 2. The baffle component 5 includes a second motor 51. A lead screw 52 is connected to the top side of the smoke outlet 21 through the second motor 51. A moving block 53 is threaded to the outer side of the lead screw 52. A baffle 54 is fixedly installed on one side of the moving block 53. Limiting rods 55 are fixedly installed on the top of the smoke outlet 21. The limiting rods 55 all pass through the baffle 54 and are slidably connected to the baffle 54.

[0028] In this embodiment, industrial waste gas is discharged through the chimney body 2 during use. The monitoring component 3 is set up to detect the waste gas flowing through the chimney body 2 at regular intervals. When the flue gas flowing inside the chimney body 2 is detected to be non-compliant with emission standards, the external controller activates the baffle component 5. The output end of the second motor 51 rotates, driving the lead screw 52 to rotate, which in turn drives the moving block 53 and the baffle 54 to move down to completely block the exhaust port 21. This helps to prevent the discharge of non-compliant flue gas. This solves the problem in related technologies where, although the discharged waste gas is detected, the gas has already been discharged when non-compliant waste gas is detected, and there is a lack of baffle for non-compliant waste gas.

[0029] The monitoring component 3 includes a fixed box 31, which is fixedly installed on the outside of the chimney body 2 near the top. The fixed box 31 has an inner cavity 32 that communicates with the inside of the chimney body 2. A rotating rod 35 is rotatably connected inside the inner cavity 32. Four partitions 36 are fixedly installed in a circular array on the outer side of the rotating rod 35. A monitoring chamber 321 is located on the side of the inner cavity 32 away from the chimney body 2. A first motor 34 is connected to the top of the fixed box 31 near the rotating rod 35 via a fixing frame 33. The output end of the first motor 34 is fixedly connected to the rotating rod 35. The top of the fixed box 31 is insulated. The housing 37 is connected to the main body 38 of the monitoring instrument. The bottom of the main body 38 of the monitoring instrument is fixedly installed with a detection probe 381, which extends into the monitoring cavity 321. By setting the monitoring component 3, the output end of the No. 1 motor 34 drives the rotating rod 35 to rotate, which in turn drives the four partitions 36 to make circular motion, continuously driving the flue gas inside the chimney body 2 into the monitoring cavity 321, and detecting it through the main body 38 of the monitoring instrument and the detection probe 381. When the detection fails, the external control system can be used to activate the baffle component 5 to continue to block the exhaust port 21, making the detection more convenient.

[0030] The cooling component 4 includes a cold water tank 41 and a water storage tank 42. An insulation cavity 43 is formed inside the insulation shell 37. A first connecting pipe 45 is connected to the top of the cold water tank 41 via a pump body 44. The first connecting pipe 45 extends into the insulation cavity 43 from the side near the insulation shell 37. A second connecting pipe 46 is fixedly installed through the insulation shell 37 from the bottom. The bottom end of the second connecting pipe 46 extends into the water storage tank 42. An inlet pipe 47 is fixedly installed through one side of the cold water tank 41, and a drain pipe 48 is fixedly installed through one side of the water storage tank 42. By setting up the cooling component 4, cold water is added to the cold water tank 41 through the inlet pipe 47 connected to an external water source, and cold water is injected into the insulation cavity 43 through the pump body 44 and the first connecting pipe 45. This is used to protect the main body 38 of the monitoring instrument during use. The water storage tank 42 facilitates the collection of water discharged from the second connecting pipe 46, saving water resources.

[0031] A support frame 39 is fixedly installed between the bottom of the fixed box 31 and the main body of the chimney 2; the support frame 39 helps to enhance the stability of the fixed box 31.

[0032] The inner cavity 32 is designed with an arc-shaped structure, and the side of the partition 36 close to the inner cavity 32 is in contact with and slidably connected to the inner cavity 32; the cooperation between the partition 36 and the inner cavity 32 makes it more convenient to use.

[0033] Among them, a one-way valve is installed on the outside of the second connecting pipe 46, and valves are installed on the outside of the inlet pipe 47 and the drain pipe 48; the one-way valve installed on the outside of the second connecting pipe 46 helps to prevent backflow inside the second connecting pipe 46.

[0034] Working principle: During use, industrial waste gas is discharged through the main body of the chimney 2. The monitoring component 3 is set to detect the waste gas flowing through the main body of the chimney 2 at regular intervals. When the flue gas flowing inside the main body of the chimney 2 is detected to be non-compliant with emission standards, the external controller activates the baffle component 5. The output end of the No. 2 motor 51 rotates, which drives the lead screw 52 to rotate. This, in turn, moves the moving block 53 and the baffle 54 downward to completely block the exhaust port 21, which helps to prevent the discharge of non-compliant flue gas.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
