[0036] Figure 2It is a flowchart of a control method for an electroplating waste gas monitoring device provided by an embodiment of the present invention. Detailed implementation manners

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0038] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present invention are used to distinguish different objects, rather than to limit a specific order. Each of the following embodiments of the present invention can be executed independently, and the embodiments can also be combined with each other. The embodiments of the present invention do not make specific limitations in this regard.

[0039] Figure 1 It is a structural diagram of an electroplating waste gas monitoring device provided by an embodiment of the present invention.

[0040] The electroplating waste gas monitoring device is applied to an electroplating workshop. At least one electroplating device is provided in each electroplating workshop, and a waste gas top suction main channel is provided at the top of each electroplating workshop. A waste gas top suction sub-channel is provided at the top of each electroplating device; as Figure 1 shown, the electroplating waste gas monitoring device includes:

[0041] At least one detection module 10, which is arranged on the electroplating device and is used to detect whether there is hydrogen cyanide gas leakage in the electroplating device, and generate a color change when there is leakage. Among them, the color change of the detection module 10 is positively correlated with the concentration of the leaked gas;

[0042] An identification module 20, which is used to identify the color change state of the detection module 10; a control module 30, which is configured to send a hierarchical warning instruction to a hierarchical warning module 40 based on the color change state; a hierarchical warning module 40, which is configured to perform warning actions of different levels based on the hierarchical warning instruction.

[0043] Specifically, since the electroplating device will generate highly toxic hydrogen cyanide gas during electroplating, it is usually a closed device. The waste gas generated by it will be inhaled into the waste gas top suction sub-channel through the top suction device, and then enter the waste gas tower for treatment. If the top suction device is not turned on in time, or the power is low resulting in insufficient inhalation, there may be a situation of waste gas leakage, which poses a hazard to the personal safety of the staff in the electroplating workshop.

[0044] Therefore, a detection module 10 is provided at the connection between the top of the electroplating equipment and the exhaust gas top suction channel. A colorimetric reagent that can react with hydrogen cyanide gas to produce a blue-violet compound is provided in the detection module 10. When encountering leaked hydrogen cyanide gas, the detection module 10 reacts to produce a color change. The recognition module 20 can identify the color change state of the detection module 10 in real time to determine the leakage concentration of hydrogen cyanide gas.

[0045] The control module 30 controls the hierarchical alarm module 40 to perform alarm actions at different levels according to the color change state identified by the recognition module 20, so as to prompt the staff in the workshop that there is exhaust gas leakage and they need to evacuate and carry out subsequent processing.

[0046] By providing a detection module on the electroplating equipment that can react with hydrogen cyanide gas to produce a color change and performing alarm prompts at different levels when detecting leaks of hydrogen cyanide at different concentrations, the present invention solves the technical problem that the existing electroplating workshop has potential safety hazards due to the lack of an exhaust gas leakage monitoring device, and achieves the technical effects of improving the safety of the electroplating workshop and ensuring the personal safety of the workshop production personnel.

[0047] Optionally, the hierarchical alarm module 40 includes a first-level alarm sub-module and a second-level alarm sub-module; the control module 30 is configured to send a first-level alarm instruction to the first-level alarm sub-module when the color change state is within the first concentration range; the control module 30 is further configured to send a second-level alarm instruction to the second-level alarm sub-module when the color change state is within the second concentration range.

[0048] Specifically, the first concentration range can be set to 10 - 20 ppm (Parts Per Million) as needed, and the second concentration range can be set to be greater than 20 ppm as needed. When within the first concentration range, the control module 30 sends a first-level alarm instruction to the first-level alarm sub-module, so that the first-level alarm sub-module performs the alarm actions required when the leaked gas is within the first concentration range under the control of this instruction; when within the second concentration range, the control module 30 sends a second-level alarm instruction to the second-level alarm sub-module, so that the second-level alarm sub-module performs the alarm actions required when the leaked gas is within the second concentration range under the control of this instruction.

[0049] Optionally, the first-level alarm sub-module includes a first audio-visual alarm device and a standby fan.

[0050] The first audio-visual alarm device is set at a set position in the electroplating workshop and in the workshop control room, and is used to prompt relevant personnel to evacuate by using stroboscopic lights and beeping sounds; the standby fan includes a first standby fan set at the main exhaust gas top suction channel and a second standby fan set at the exhaust gas top suction sub-channel, and is used to blow the leaked hydrogen cyanide gas into the exhaust gas top suction channel.

[0051] Specifically, when the control module 20 sends a first-level alarm instruction to the first-level alarm sub-module, in the first-level alarm sub-module, the first acoustic-optic alarm devices at the entrance of the electroplating workshop and the working positions of the staff will emit acoustic-optic warnings to prompt the staff in the workshop that there is a leakage of hydrogen cyanide gas and they need to evacuate the electroplating workshop quickly. Then, the first standby fan arranged at the main exhaust top-suction channel and the second standby fan arranged at the sub-exhaust top-suction channel will both start. On the one hand, the second standby fan assists in blowing the waste gas leaked from the electroplating equipment into the sub-exhaust top-suction channel. On the other hand, the first standby fan assists in blowing the waste gas diffused in the electroplating workshop into the main exhaust top-suction channel, so as to send the leaked gas back to the exhaust gas tower for treatment.

[0052] In the embodiment of the present invention, by arranging standby fans at different positions to blow the leaked gas back into the top-suction channel for treatment, the relatively low-concentration toxic gas leaked can be treated quickly and effectively. At the same time, the first acoustic-optic alarm devices at different positions in the electroplating workshop can immediately remind the staff in the workshop of the gas leakage problem and they need to evacuate as soon as possible, effectively ensuring the personal safety of the production personnel in the electroplating workshop.

[0053] Optionally, the second-level alarm sub-module includes a second acoustic-optic alarm device, a spraying system, and a switch unit.

[0054] The second acoustic-optic alarm device is arranged at the set positions in the electroplating workshop and in the workshop control room, and is used to prompt relevant personnel to evacuate by means of light strobing and beeping prompt sounds; the spraying system is arranged at the top of the electroplating workshop and is used to spray sodium hypochlorite solution to absorb the leaked hydrogen cyanide gas; the switch unit is used to cut off the power supply of the electroplating tank in the electroplating equipment.

[0055] Specifically, when the control module 20 sends a second-level alarm instruction to the second-level alarm sub-module, in the second-level alarm sub-module, the second acoustic-optic alarm devices at the entrance of the electroplating workshop and the working positions of the staff will emit acoustic-optic warnings to prompt the staff in the workshop that there is a leakage of hydrogen cyanide gas and they need to evacuate the electroplating workshop quickly. It should be noted that the second acoustic-optic alarm device can be set as the same batch of devices as the first acoustic-optic alarm device according to needs, so as to streamline the workshop wiring layout and reduce the production cost.

[0056] While the second acoustic-optic alarm device starts to give a warning, the spraying system starts to spray sodium hypochlorite solution to absorb the relatively high-concentration hydrogen cyanide gas leaked and eliminate the toxicity of the waste gas diffused in the air. The switch unit is linked to cut off the power supply of the electroplating tank in the electroplating equipment, stopping the generation of waste gas from the source and avoiding the leakage of more highly toxic gases.

[0057] In an embodiment of the present invention, when there is a leakage of hydrogen cyanide gas at a relatively high concentration, the spraying system is activated to absorb the leaked gas, and the power supply of the electroplating tank is cut off to avoid the continuous generation of toxic waste gas. At the same time, the second acoustic and optical warning devices at different positions in the electroplating workshop can immediately remind the staff in the workshop that there is a gas leakage problem and they need to evacuate as soon as possible, effectively ensuring the personal safety of the production personnel in the stack workshop and also preventing the diffusion of toxic gas outside the electroplating workshop.

[0058] Optionally, both the first-level warning sub-module and the second-level warning sub-module include communication devices; the communication devices are used to send warning information to the communication devices of designated personnel.

[0059] Specifically, in order to further improve the early warning ability of waste leakage, communication devices are also provided in the first-level warning sub-module and the second-level warning sub-module. When the hierarchical warning module receives a hierarchical warning instruction, whether it is a first-level warning instruction or a second-level warning instruction, the corresponding warning sub-module will send the warning information of gas leakage to the communication devices of designated personnel. It should be noted that the communication devices can be mobile communication devices carried by designated personnel, such as mobile phones, tablets, etc., or communication terminals in the workshop control room, etc., and no specific limitation is made here.

[0060] Optionally, the detection module 10 is arranged at the connection between the electroplating equipment and the corresponding waste gas top suction sub-channel, and one detection module 10 is correspondingly arranged for one electroplating equipment; the detection module 10 includes a silica gel carrier carrying isonicotinic acid-barbituric acid chromogenic reagent.

[0061] Specifically, the detection module 10 is arranged at the connection between the top of the electroplating equipment and the waste gas top suction sub-channel. When the top suction equipment is not started in time or the power is low resulting in insufficient suction volume, there may be a situation of waste gas leakage, and the detection module 10 arranged here can detect the leaked gas in the first time.

[0062] Isonicotinic acid-barbituric acid chromogenic reagent is a reagent used in analytical chemistry, specifically for display reactions. It will produce a blue-violet compound after contacting with hydrogen cyanide gas, thus showing a color change, and the degree of color change is positively correlated with the concentration of hydrogen cyanide gas. Therefore, it can be used for the leakage detection of hydrogen cyanide gas. And silica gel is a porous material with good adsorption performance and a large specific surface area, so it is often used as a carrier. Setting the isonicotinic acid-barbituric acid chromogenic reagent on the silica gel carrier helps the chromogenic reagent to contact and react with hydrogen cyanide gas.

[0063] Optionally, the recognition module 20 includes a photoelectric colorimetric sensor.

[0064] Specifically, the photoelectric colorimetric sensor can monitor the color development intensity of the color reagent in real time, especially the blue-violet color around a wavelength of 600 nm. The detection sensitivity of the photoelectric colorimetric sensor can reach 0.5 ppm. Therefore, when setting the concentration level range for alarming, it is set in units of 1 ppm. For example, the first concentration range is set to 10 - 20 ppm, and the second concentration range is set to be greater than 20 ppm. The photoelectric colorimetric sensor sends different electrical signals to the control module 30 in different concentration ranges, so that the control module 30 sends corresponding hierarchical alarm instructions to the hierarchical alarm module 40.

[0065] Figure 2 It is a flowchart of a control method for an electroplating waste gas monitoring device provided by an embodiment of the present invention.

[0066] The electroplating waste gas monitoring device in any of the above embodiments executes this control method. As Figure 2 shown, the control method of the electroplating waste gas monitoring device specifically includes the following steps:

[0067] S201, the detection module detects whether there is hydrogen cyanide gas leakage in the electroplating equipment and generates a color change when there is leakage. Among them, the color change of the detection module is positively correlated with the concentration of the leaked gas;

[0068] S202, the recognition module recognizes the color change state of the detection module;

[0069] S203, the control module sends a hierarchical alarm instruction to the hierarchical alarm module based on the color change state;

[0070] S204, the hierarchical alarm module performs alarm actions of different levels based on the hierarchical alarm instruction.

[0071] Optionally, in S203, the control module sends a hierarchical alarm instruction to the hierarchical alarm module based on the color change state, which specifically includes:

[0072] When the color change state is in the first concentration range, the control module sends a first-level alarm instruction to the hierarchical alarm module; when the color change state is in the second concentration range, the control module sends a second-level alarm instruction to the hierarchical alarm module.
