Description

Technical Field

[0001] This utility model relates to the field of emission monitoring technology, specifically to an emission monitoring device. Background Technology

[0002] With the rapid development of industrial production, energy consumption, and transportation, the impact of various emissions (such as industrial waste gas, vehicle exhaust, and dust) on the ecological environment and human health is becoming increasingly prominent. These emissions not only contain fine particulate matter such as PM2.5 and PM10, but also SO2 and NOx. x VOCs (volatile organic compounds), CO and other gaseous pollutants are the core causes of smog and acid rain, as well as important risk factors for respiratory and cardiovascular diseases. Therefore, accurate, real-time and efficient monitoring of emissions has become a core link in pollution prevention and control, environmental governance and public health protection.

[0003] However, most existing environmental pollution monitoring equipment has a fixed installation design, which means that when the emission monitoring device is damaged, it cannot be quickly disassembled for replacement and maintenance, making it inconvenient to use. At the same time, it generally does not remove dust particles in the air when detecting gases, resulting in inaccurate data. Utility Model Content

[0004] The purpose of this invention is to provide an emission monitoring device to solve the problems mentioned in the background art, such as inconvenience in disassembly and maintenance and inaccurate detection due to the failure to remove dust particles in the air.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an emission monitoring device, comprising a mounting column and a housing, wherein the mounting column is fixedly installed at the location to be monitored, the outer surface of the housing is provided with an observation window, and an air monitoring sensor is fixedly installed inside the housing, a sleeve is fixedly installed on the outer surface of one end of the housing, and the sleeve is inserted into the mounting column, a T-shaped groove is formed on the outer surface of the housing near the mounting column, the T-shaped groove of the housing is covered by the sleeve, and a spring pin is slidably installed on the end of the mounting column away from the ground, and the spring pin engages with the T-shaped groove of the housing.

[0006] Preferably, an air intake pipe is installed through one side surface of the box, and a windproof shield is fixedly installed on the outer surface of one end of the air intake pipe. A particulate matter detection sensor is fixedly installed inside the box and is connected to the air intake pipe.

[0007] By adopting the above technical solution, when the monitoring device is used in an outdoor space, a windproof shield can be used to prevent rainwater from entering the monitoring device, allowing air to be drawn into the particulate matter detection sensor to monitor dust particles in the emissions of the surrounding atmosphere. The air intake pipe is higher than the housing, so that the monitoring device is not obstructed when drawing in the surrounding air, and can collect air evenly, reducing the chance of inaccurate monitoring.

[0008] Preferably, a suction sampling pump is fixedly installed inside the housing, and one end of the suction sampling pump is connected to a particulate matter detection sensor, and a flow rate sensor is connected between the particulate matter detection sensor and the suction sampling pump.

[0009] By adopting the above technical solution, the gas flow rate of the suction sampling pump can be monitored by a flow rate sensor, enabling the suction sampling pump to uniformly extract the surrounding gas and reduce measurement inaccuracies caused by unstable gas flow.

[0010] Preferably, an air filter is fixedly installed inside the housing, and the input end of the air filter is connected to the output end of the suction sampling pump. An air monitoring sensor is fixedly installed inside the housing, and the output end of the air filter is connected to the air monitoring sensor.

[0011] By adopting the above technical solution, the incoming air can be filtered and separated through an air filter, so that dust particles in the air can be filtered out and removed. The filtered air can then enter the air monitoring sensor, ensuring that the detection results are not affected by dust during the detection process, thus greatly improving the monitoring effect of the air monitoring sensor.

[0012] Preferably, the outer surface of the air filter is threaded with an electromagnetic valve, and the output end of the electromagnetic valve penetrates through the outer surface of the housing.

[0013] By adopting the above technical solution, the solenoid valve can be opened at regular intervals to periodically discharge the dust and water separated from the air filter, thereby automatically discharging the dust and reducing the chance of blockage and excessive dust entering the air monitoring sensor.

[0014] Preferably, a control terminal is fixedly installed inside the enclosure, a data exchange terminal is fixedly installed at the end of the enclosure away from the control terminal, and a wind speed sensor is fixedly installed at the end of the enclosure away from the windproof shield.

[0015] By adopting the above technical solution, the data detected by the particulate matter detection sensor and the air monitoring sensor can be uploaded and exchanged through the data exchange terminal, allowing the testing personnel to remotely obtain the data measured at each monitoring point and control the operation of each component inside the box through the control terminal.

[0016] Preferably, a fan is fixedly installed on the outer surface of the box near the air intake pipe, and a dustproof net is fixedly installed on the outer surface of the fan. A louvered waterproof cover is fixedly installed on the end of the box near the air intake pipe, and the louvered waterproof cover covers the air monitoring sensor and the fan. An exhaust shield is installed through the end of the box away from the louvered waterproof cover, and the exhaust shield is designed to be inclined.

[0017] By adopting the above technical solution, external air can be drawn into the interior of the enclosure by a fan, and a louvered waterproof cover can be used to prevent rainwater from entering the enclosure during air extraction, thus preventing short circuits and damage. A dustproof net can also be used to prevent dust from entering the enclosure, and the inclined design of the exhaust shield can prevent rainwater from flowing into the enclosure, thereby reducing the internal temperature of the enclosure and preventing the possibility of damage from rainwater entering the enclosure.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the emission monitoring device:

[0019] 1. First, when using the device, the mounting column needs to be fixedly installed around the location where the emissions need to be monitored. Then, the box can be inserted into the outer surface of the mounting column and locked into the inside of the box by the spring pin. This allows the box to be easily installed and fixed to the mounting column. At the same time, the sleeve can prevent rainwater from entering the box. When the box needs to be quickly removed, the box can only be opened and the spring pin can be pressed to disengage the spring pin from the box. This allows the box to be quickly assembled and installed with the mounting column, and it can only be removed from the inside. This improves the convenience of installation and disassembly while also enhancing theft prevention.

[0020] 2. By using a suction sampling pump, the surrounding air can be drawn into the particulate matter detection sensor through the suction pipe to monitor the particulate matter in the air. After the monitoring is completed, the air can be filtered through an air filter and re-enter the air monitoring sensor, so that the detection device can monitor the particles in the air and remove the particles in the air for monitoring. This improves the monitoring accuracy and also allows for the monitoring of the number and size of the particles in the air.

[0021] 3. The speed of the suction sampling pump can be monitored through the control terminal, and the flow rate sensor can monitor the air flow rate. This ensures that the air enters the particulate matter detection sensor and the air monitoring sensor at a uniform speed, reducing measurement errors caused by uneven air flow. The detected data can also be uploaded through the data exchange terminal to remotely obtain the monitoring data of each detection point.

[0022] 4. The louvered waterproof cover can shield the fan and air monitoring sensor, preventing external rainwater from entering the enclosure when the fan draws in air or the air monitoring sensor exhausts air. The inclined design of the exhaust cover and the exhaust airflow also prevent rainwater from entering the enclosure, reducing the chance of water ingress and short circuits while ensuring ventilation and cooling of the enclosure.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Please see Figure 1-6This utility model provides a technical solution: an emission monitoring device, including a mounting column 1 and a housing 2. The mounting column 1 is fixedly installed at the location where the monitoring is required. An observation window is provided on the outer surface of the housing 2, and an air monitoring sensor 12 is fixedly installed inside the housing 2. A sleeve 3 is fixedly installed on the outer surface of one end of the housing 2, and the sleeve 3 is inserted into the mounting column 1. A T-shaped groove is opened on the outer surface of the housing 2 near the mounting column 1, and the T-shaped groove of the housing 2 is covered by the sleeve 3. A control terminal 16 is fixedly installed inside the housing 2. A data exchange terminal 17 is fixedly installed on the end of the housing 2 away from the control terminal 16. A wind speed sensor 18 is fixedly installed on the end of the housing 2 away from the windproof shield 6. A spring pin 4 is slidably installed on the end of the mounting column 1 away from the ground, and the spring pin 4 is engaged with the T-shaped groove of the housing 2.

[0032] First, during installation, the mounting column 1 needs to be fixed at the location surrounding the emissions to be measured. Then, the housing 2 can be lifted and connected to the mounting column 1 via the sleeve 3, allowing the mounting column 1 to be installed with the housing 2. The spring pin 4 can then be engaged in the T-shaped groove of the housing 2, greatly improving the convenience of installation. During disassembly, the housing 2 can only be opened and the spring pin 4 can be pressed down to disengage it from the housing 2. The sleeve 3 can fix the housing 2 and prevent rainwater from entering the interior of the housing 2, greatly improving the convenience of installation, disassembly, and maintenance of the monitoring device, while also enhancing its anti-theft capabilities.

[0033] A suction sampling pump 9 is fixedly installed inside the housing 2, and one end of the suction sampling pump 9 is connected to a particulate matter detection sensor 7. A flow rate sensor 8 is connected between the particulate matter detection sensor 7 and the suction sampling pump 9. An air filter 10 is fixedly installed inside the housing 2, and the input end of the air filter 10 is connected to the output end of the suction sampling pump 9. A solenoid valve 11 is threaded on the outer surface of the air filter 10, and the output end of the solenoid valve 11 passes through the outer surface of the housing 2. An air monitoring sensor 12 is fixedly installed inside the housing 2, and the output end of the air filter 10 is connected to the air monitoring sensor 12.

[0034] Secondly, during sampling and monitoring, the control terminal 16 controls the suction sampling pump 9 to operate and monitors the airflow through the flow rate sensor 8, allowing external air to be drawn into the particulate matter detection sensor 7 through the suction pipe 5 to monitor the particulate matter in the air. After the detection is completed, the gas enters the air filter 10, where the air filter 10 filters and separates the dust particles in the air, allowing the filtered gas to enter the air monitoring sensor 12 to monitor the composition of the air again, reducing the impact of particulate matter in the air on the detection of the air monitoring sensor 12. The measured data can be sent and exchanged through the data exchange terminal 17, allowing the testing personnel to remotely obtain data from multiple monitoring points. The monitoring device can simultaneously detect particulate matter and gas components in the air. After a period of time, the control terminal 16 opens the solenoid valve 11 to automatically discharge the particulate matter filtered out of the air filter 10, greatly improving the practicality of the monitoring device.

[0035] A fan 13 is fixedly installed on the outer surface of the end of the housing 2 near the air intake pipe 5, and a dustproof net 19 is fixedly installed on the outer surface of the end of the fan 13. A louvered waterproof cover 15 is fixedly installed on the end of the housing 2 near the air intake pipe 5, and the louvered waterproof cover 15 covers the air monitoring sensor 12 and the fan 13. An exhaust shield 14 is installed through the end of the housing 2 away from the louvered waterproof cover 15, and the exhaust shield 14 is designed to be tilted.

[0036] Furthermore, the windproof shield 6 effectively prevents external rainwater from entering the air intake pipe 5. At the same time, the wind speed sensor 18 can monitor the external air flow rate, reducing the inaccuracy of detection caused by external weather. The fan 13 can draw external air into the housing 2 and discharge it through the exhaust shield 14, reducing the internal operating temperature of the monitoring device. The inclined design of the exhaust shield 14 reduces the probability of rainwater flowing into the housing 2 from the exhaust shield 14. The dustproof net 19 can prevent dust from entering the housing 2. At the same time, the use of the louvered waterproof cover 15 can further prevent rainwater from entering the housing 2, greatly improving the waterproof performance of the monitoring device.

[0037] Working principle: When monitoring emissions in the air around the detection site, the suction sampling pump 9 is controlled by the control terminal 16, and the flow rate of the intake air is monitored by the flow rate sensor 8. The air can pass through the windproof shield 6 and enter the particulate matter detection sensor 7. The particulate matter detection sensor 7 monitors the particles in the air, and the air after detection is discharged into the air filter 10 through the suction sampling pump 9. After the air filter 10 filters the air and removes the particles, it is discharged into the air monitoring sensor 12 for detection again, so as to detect both the particles and components in the air. After a period of time, the solenoid valve 11 is opened by the control terminal 16 to discharge the particles in the air filter 10, so that the dust particles can be automatically discharged to reduce the chance of overflow. The air drawn in by the fan 13 can also cool the inside of the chamber 2, improving the diversity and accuracy of the monitoring data during use.

[0038] When a component inside the housing 2 malfunctions after a period of use, simply open the housing 2 and press the spring pin 4 with a tool to disengage the spring pin 4 from the housing 2. Then, the housing 2 can be removed from the mounting column 1 to facilitate taking the malfunctioning housing 2 away for repair and inserting the intact housing 2 back onto the mounting column 1, thus improving the convenience of installation, disassembly, and maintenance.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
