[0002] An acid mist monitoring device is a device used to detect and monitor indicators such as the concentration and content of acid mist in the environment. It can continuously and in real time monitor acid mist and provide more accurate and detailed analysis results. It is often used in industrial production processes or environmental monitoring stations with strict requirements for acid mist emissions to ensure the safety of the production environment, prevent acid mist from corroding equipment and causing health hazards to operators, and help enterprises meet environmental emission requirements.

[0003] A search revealed Chinese Patent Publication No. CN220323253U, which discloses an atmospheric acid mist analysis and monitoring device, belonging to the field of atmospheric environmental monitoring technology. The device includes a base plate, a mounting connector, and two rain shields. An analysis and monitoring instrument is mounted on the upper surface of the base plate, and a data connector is mounted on the upper surface of the analysis and monitoring instrument. One end of the mounting connector is inserted into the data connector. An adjustment mechanism allows for easy adjustment of the angles of the rain shields and solar panels. In sunny weather, the two sets of solar panels can be parallel with their slopes facing south, ensuring the photoelectric conversion efficiency of the solar panels. In rainy weather, the two sets of solar panels can be arranged in a V-shape to shield the analysis and monitoring instrument from rain, preventing rainwater from seeping into the instrument and affecting its lifespan. Although the angle of the rain shield and solar panels can be adjusted, the focus is only on rain protection and improved photoelectric conversion efficiency, ignoring the fact that the acid mist monitoring device is often in a complex and humid environment, which poses a risk of leakage due to electrical faults, seriously threatening the personal safety of operators and the stable operation of the equipment itself. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an acid mist monitoring device, which aims to improve the existing technology where acid mist monitoring devices are often in complex and humid environments, and there is a risk of leakage due to electrical faults, which poses a serious threat to the personal safety of operators and the stable operation of the equipment itself.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an acid mist monitoring device, comprising a housing, a power supply fixedly connected to the right rear side of the inner wall of the housing, a leakage current switch fixedly connected to the top right rear side of the inner wall of the housing, a time relay fixedly connected to the left side of the leakage current switch, two detectors fixedly connected to the top left rear side of the inner wall of the housing, the two detectors being interconnected, a filter fixedly connected to the left rear side of the inner wall of the housing, a condenser fixedly connected to the bottom right rear side of the inner wall of the housing, a drain pump fixedly connected to the bottom left rear rear side of the inner wall of the housing, a connecting mounting plate fixedly connected to the bottom right side of the housing, multiple connecting holes being provided on the right side of the connecting mounting plate, and a sealing operating mechanism provided on the front interior side of the housing.

[0016] As a further description of the above technical solution:

[0017] The bottom of the box is fixedly connected to four support legs, and the bottom of each support leg is designed to be non-slip.

[0018] Through the above technical solution: the support legs located at the four corners at the bottom of the box serve to support the entire device, making it stable on the ground or other supporting surfaces. The bottom adopts an anti-slip design, which increases the friction with the supporting surface and prevents the device from moving easily due to accidental collisions or external forces, thus providing a stable basic environment for the acid mist monitoring process.

[0019] As a further description of the above technical solution:

[0020] Two mounting feet are fixedly connected to the left and right rear ends of the housing, and mounting holes are provided on the front of each of the mounting feet.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an acid mist monitoring device, comprising a housing 1. The housing 1 serves as the outer shell of the entire acid mist monitoring device, providing protection and support for the internal components and ensuring that each component operates in a stable environment. A power supply 3 is fixedly connected to the rear right end of the inner wall of the housing 1. The power supply 3 provides stable power to each component of the device, enabling them to operate normally and ensuring the continuous operation of acid mist monitoring. A leakage current switch 4 is fixedly connected to the top right end of the rear side of the inner wall of the housing 1. The leakage current switch 4 monitors the circuit leakage in real time. Once leakage occurs, it can quickly cut off the circuit, effectively protecting the safety of operators and the equipment from leakage hazards, ensuring the safety of the entire monitoring process. For safety, a time relay 5 is fixedly connected to the left side of the leakage current switch 4. The time relay 5 controls the circuit to turn on or off in a specific time sequence, so that each component starts in an orderly manner, avoiding damage to the equipment caused by instantaneous current surges, and ensuring smooth start-up and stable operation of the equipment. Two detectors 6 are fixedly connected to the top left end of the rear side of the inner wall of the enclosure 1. The two detectors 6 are interconnected. The detectors 6 use high-precision sensors to accurately detect the acid mist components and convert information such as acid mist concentration into electrical signals, providing core support for accurately obtaining acid mist monitoring data and realizing effective monitoring of acid mist. A filter 7 is fixedly connected to the rear left end of the inner wall of the enclosure 1. The filter 7 can effectively remove acid mist. To prevent dust particles and water vapor from affecting the detection accuracy of the detector 6, and to protect the sensor and extend its service life, ensuring the accuracy of the monitoring data, a condenser 8 is fixedly connected to the bottom right end of the rear side of the inner wall of the housing 1. The condenser 8 cools the water vapor into liquid water, reducing the water vapor content in the acid mist, further improving detection accuracy and ensuring the reliability of the monitoring results. A drain pump 9 is fixedly connected to the bottom left end of the rear side of the inner wall of the housing 1. The drain pump 9 promptly drains the water accumulated by the condenser 8, preventing water accumulation from corroding and damaging the equipment, and maintaining the normal operation of the equipment. A connecting mounting plate 10 is fixedly connected to the bottom right side of the housing 1. The mounting plate 10 facilitates the installation of the device, ensuring that the device can be stably installed in the designated location and that the monitoring work can be carried out in a suitable environment. Multiple connection holes 11 are provided on the right side of the mounting plate 10. The connection holes 11 are used to connect external equipment or pipelines to realize functions such as sampling, drainage, and venting, ensuring the normal flow of gas and liquid and ensuring the smooth progress of the entire monitoring process. A sealing operation mechanism 2 is provided on the front side of the interior of the housing 1. The sealing operation mechanism 2 realizes the sealing and operation control of the housing 1, which facilitates the operator to perform parameter setting, data viewing and other operations. At the same time, it prevents external impurities from entering the housing 1 and affecting the monitoring results, thereby improving the functionality and ease of use of the device.

[0039] Specifically, power supply 3 provides the necessary electrical energy for the entire device, enabling its components to operate normally. Leakage switch 4 is connected to power supply 3 and monitors leakage in the circuit in real time. Once leakage is detected, it immediately cuts off the circuit, protecting operator safety and preventing equipment damage. Time relay 5 controls the circuit to connect or disconnect at specific times during device startup, ensuring that components start sequentially and avoiding the impact of excessive instantaneous current on the equipment, thus enabling a smooth startup. One sampling inlet is the primary channel for acid mist to enter the device. Acid mist from the external environment is drawn into the device through this sampling inlet. The acid mist first enters filter 7, which effectively removes dust particles contained in the acid mist, preventing these impurities from entering the device. The continuous detector 6 affects the detection accuracy of the sensor and can also treat the water vapor in the acid mist. Part of the treated gas continues to flow to detector 6, while the other part is discharged through the dual-path filtration and dehydration gas outlet. This helps maintain stable air pressure inside filter 7, ensuring continuous and effective filtration and dehydration, and further improving the purity of the acid mist sample entering detector 6. The pre-treated acid mist enters two interconnected detectors 6. The high-precision sensors inside detector 6 accurately detect hydrochloric acid mist, nitric acid mist, chromic acid mist, hydrogen cyanide, and sulfuric acid mist in the acid mist, converting information such as the concentration of acid mist into electrical signals for subsequent data processing and analysis. During monitoring, when the ambient humidity is high or the acid mist contains a large amount of water vapor... Condenser 8 starts working, condensing water vapor into liquid water through cooling, thereby reducing the water vapor content in the acid mist and further improving the accuracy of detection. The condensed liquid water flows to the bottom of the chamber 1 under gravity. At this time, drain pump 9 starts to discharge the accumulated water from the chamber 1 in a timely manner to prevent water from damaging the equipment. The exhaust port for the gas after detection is responsible for discharging the gas after detection by detector 6. After the acid mist completes the detection process in the device, the detected gas leaves the device through this exhaust port, maintaining the dynamic balance of the gas inside the device and ensuring the continuous and stable operation of the entire monitoring process. Without this exhaust port, the detected gas would remain in the device, interfering with the subsequent entry and detection of acid mist and affecting the monitoring data. While ensuring accuracy, this could also negatively impact the internal components of the device. The connecting mounting plate 10 is located at the bottom right side of the housing 1. Multiple connection holes 11 on its right side serve different functions: sampling holes, venting holes, drain holes, and reserved holes. The sampling holes act as the entry point for acid mist into the system, ensuring accurate acquisition of acid mist samples within the monitoring area. The venting holes are used to expel the detected gas from the device during operation, ensuring smooth gas flow and stable internal pressure. The drain holes drain accumulated water from the device, preventing moisture buildup from causing corrosion and damage. The reserved holes provide possibilities for functional expansion and future improvements, facilitating the connection of new equipment or pipelines to adapt to technological advancements and changing user needs.The entire device achieves accurate monitoring of acid mist and is suitable for acid mist monitoring needs in various environments. It can be applied to environmental monitoring at factory boundaries, industrial waste gas emissions, and special locations such as agricultural greenhouses.

[0041] Specifically, inner sealing door panel 1 201 is rotatably connected to the top left side of the inner wall of housing 1, and inner sealing door panel 205 is rotatably connected to the bottom left side of the inner wall of housing 1, allowing the doors to be opened and closed flexibly. When operation or maintenance of the interior of housing 1 is required, the operator can easily open the door panel, and after the operation is completed, the door panel can be closed to ensure the airtightness of the interior of housing 1. During daily monitoring, the door panel is closed to prevent external impurities or interference factors from entering housing 1 and affecting the monitoring results. The control panel 202 fixed in the middle of the front side of inner sealing door panel 1 201 is the control center of the entire operation. The adjustment button 203 on the left side of the front side of the control panel 202 can be used to adjust various parameters of the monitoring device. The operator can accurately set the parameters by pressing the adjustment button 203 according to the actual monitoring needs. The touch screen 204 on the right side provides a more intuitive and convenient operating interface, which can display monitoring data and equipment status information, and can also... The device allows for function selection and data viewing via touch operation. For example, when viewing real-time acid mist concentration data or historical monitoring data, the operation can be easily completed through the touch screen 204. The inner handle 206, which is fixed to the front right end of both inner sealing door panel 1 201 and inner sealing door panel 205, is mainly for the convenience of operators to open and close the door panels. When it is necessary to open the door panel, the operator holds the inner handle 206 and applies a certain force to make the door panel rotate around the rotating connection to open. When closing the door panel, the operator also uses the inner handle 206 to pull the door panel back to the closed position to ensure that the door panel is tightly closed and to maintain the sealed environment inside the chamber 1. When it is necessary to inspect, repair or replace the internal components of the chamber 1, the inner handle 206 makes the operation more convenient and efficient. Overall, it effectively ensures the internal sealing of the chamber 1, prevents external dust and moisture impurities from entering, ensures that the accuracy of monitoring data is not affected by external factors, and improves the operational efficiency and the functionality and ease of use of the monitoring device.

[0042] Reference Figure 1 and Figure 2Cooling fans 12 are fixedly installed on the lower middle part of the left and right sides of the enclosure 1. The two cooling fans 12 have opposite ventilation directions, which can form effective convection in the enclosure 1, quickly dissipate the heat generated by the internal components during operation, effectively prevent the performance degradation or damage of the components due to overheating, and ensure the continuous and stable operation of the acid mist monitoring device. A rainproof top plate 13 is fixedly connected to the top of the enclosure 1. The rainproof top plate 13 is trapezoidal and smaller at the top and larger at the bottom. This shape is conducive to the rapid sliding of rainwater, effectively blocking rainwater from directly invading the enclosure 1, avoiding rainwater from entering the interior and causing short circuits or corrosion of components, providing reliable rain protection for the equipment inside the enclosure 1, and ensuring that the acid mist monitoring work is not affected by rainfall. Support legs 14 are fixedly connected to the four corners of the bottom of the enclosure 1. The anti-slip design of the bottom of the multiple support legs 14 can not only stably support the entire device and keep it balanced, but also prevent the device from moving easily due to accidental collisions or external forces, providing a solid and stable foundation environment for acid mist monitoring, and ensuring the accuracy and reliability of monitoring data.

[0043] Specifically, the two cooling fans 12 have opposite ventilation directions, which can create good air convection inside the enclosure 1. One fan draws out the hot air inside the enclosure 1, while the other introduces cool air from the outside, accelerating heat dissipation and effectively reducing the heat generated by the components inside the enclosure 1 during operation. This prevents the components from degrading or being damaged due to overheating. The trapezoidal rainproof top plate 13, with its shape that is smaller at the top and larger at the bottom, allows rainwater to slide off quickly and is less likely to accumulate on the top. When used outdoors, it can effectively prevent rainwater from directly hitting the enclosure 1, preventing rainwater from entering the enclosure 1 and causing short circuits or corrosion of internal components. This protects the equipment inside the enclosure 1 and extends the service life of the device. The support legs 14 located at the four corners at the bottom of the enclosure 1 support the entire device, allowing it to be placed stably on the ground or other supporting surfaces. The bottom is designed with anti-slip properties, increasing the friction with the supporting surface and preventing the device from moving easily due to accidental collisions or external forces, thus providing a stable base environment for the acid mist monitoring process.

[0046] Working principle: Power supply 3 provides the necessary electrical energy for the entire device. Leakage switch 4 is connected to power supply 3 and monitors leakage in the circuit in real time. Once leakage is detected, the circuit is immediately cut off. Time relay 5 controls the circuit to connect or disconnect after a specific time during device startup, preventing excessive instantaneous current from impacting the equipment and ensuring a smooth start-up. One sampling inlet is the primary channel for acid mist to enter the device. Acid mist from the external environment is drawn into the device through this sampling inlet. The acid mist first enters filter 7, which effectively removes dust contained in the acid mist. Particulate matter is removed to prevent impurities from entering the subsequent detector 6 and affecting the sensor's detection accuracy. Simultaneously, water vapor in the acid mist is treated. Part of the treated gas continues to flow to detector 6, while the other part is discharged through the dual-path filtration and dehydration gas outlet. This helps maintain stable air pressure inside filter 7, ensuring continuous and effective filtration and dehydration, further improving the purity of the acid mist sample entering detector 6. The pre-treated acid mist enters two interconnected detectors 6. The high-precision sensors inside detector 6 detect hydrochloric acid mist, nitric acid mist, chromic acid mist, hydrogen cyanide, and other components in the acid mist. Accurate detection of sulfuric acid mist converts information such as the concentration of acid mist into electrical signals for subsequent data processing and analysis. During monitoring, when the ambient humidity is high or the acid mist contains a large amount of water vapor, condenser 8 starts working. Condenser 8 cools the water vapor into liquid water, thereby reducing the water vapor content in the acid mist and further improving the accuracy of detection. The condensed liquid water flows to the bottom of the chamber 1 under gravity. At this time, drain pump 9 starts to promptly drain the accumulated water from the chamber 1 to prevent water from damaging the equipment. The gas outlet after one detection is responsible for discharging the gas that has passed through detector 6. The gas exhaust device is used to discharge the gas after the acid mist has completed the detection process inside the device. After the acid mist has completed the detection process, the gas after detection leaves the device through this exhaust port, maintaining the dynamic balance of the gas inside the device and ensuring the continuous and stable operation of the entire monitoring process. Without this exhaust port, the gas after detection will remain in the device, which will interfere with the subsequent entry and detection of acid mist, affect the accuracy of the monitoring data, and also have an adverse effect on the internal components of the device. The connecting mounting plate 10 is located at the bottom right side of the box 1. The multiple connecting holes 11 opened on its right side have different functions, namely sampling holes, venting holes, drain holes and reserved holes.

[0047] Furthermore, the inner sealing door panel 201 is rotatably connected to the top left side of the inner wall of the enclosure 1, and the inner sealing door panel 205 is rotatably connected to the bottom left side of the inner wall of the enclosure 1, allowing the doors to be opened and closed flexibly. When operation or maintenance of the interior of the enclosure 1 is required, the operator can easily open the door panel, and after the operation is completed, the door panel can be closed to ensure the airtightness of the interior of the enclosure 1. During daily monitoring, the door panel is closed to prevent external impurities or interference factors from entering the enclosure 1 and affecting the monitoring results. The control panel 202 fixed in the middle of the front side of the inner sealing door panel 201 is the control center of the entire operation. The adjustment button 203 on the left side of the front side of the control panel 202 can be used to adjust various parameters of the monitoring device. The operator can achieve precise parameter settings by pressing the adjustment button 203 according to the actual monitoring needs. The touch screen 204 on the right side provides... A more intuitive and convenient operating interface is provided, which can display monitoring data and equipment status information, and can select functions and view data through touch operation. For example, when viewing real-time acid mist concentration data or historical monitoring data, the operation can be easily completed through the touch screen 204. The inner handle 206 fixed on the front right end of the inner sealing door panel 1 201 and inner sealing door panel 205 is mainly to facilitate the operator to open and close the door panel. When it is necessary to open the door panel, the operator holds the inner handle 206 and applies a certain force to make the door panel rotate around the rotating connection to open. When closing the door panel, the operator also uses the inner handle 206 to pull the door panel back to the closed position to ensure that the door panel is tightly closed and maintain the sealing environment inside the box 1. When it is necessary to inspect, repair or replace the internal components of the box 1, the inner handle 206 makes the operation more convenient and efficient.
