PM2.5 Sensor for Dust Monitoring in Chemical Plants

In chemical plant dust monitoring, PM2.5 sensors are widely used to monitor fine particles in the air to ensure a safe working environment and compliance with environmental standards. 

The following are the general steps for the use of PM2.5 sensors in chemical plant dust monitoring:

1. Select the right PM2.5 sensor: Select the right PM2.5 sensor according to the specific needs of the chemical plant. Considering that chemical plants may have harsh environments such as corrosive gases and high temperatures, sensors with corrosion resistance and high temperature protection should be selected.

2. Installation of the sensor: Install the PM2.5 sensor in the dusty areas of the chemical plant, such as the entrance to the workshop, in the air above the material conveyor belt, or near a specific pollution source. Ensure that the sensor is in a location where it can easily capture dust and not be disturbed by other factors.

3. Connecting circuitry and software: Connect the sensor to the control circuitry and data acquisition system. Use appropriate programming software or monitoring system to configure sensor parameters such as sampling rate, alarm thresholds, etc.

4. Data Acquisition and Analysis: The sensor will collect real-time data on the concentration of PM2.5 particulate matter in the air and transmit it to a computer or other display device via the data acquisition system. Analysis software is used to interpret the data and generate real-time reports.

5. Setting the alarm system: Set alarm thresholds for PM2.5 concentration according to national and local environmental standards. When the PM2.5 concentration detected by the sensor exceeds the preset threshold, the system will automatically trigger an alarm to notify staff to take appropriate control measures.

6. Adoption of control measures: When the alarm is triggered, the staff of the chemical plant should adopt appropriate control measures based on the monitoring data, such as adjusting the production process, increasing the frequency of use of cleaning equipment, and shutting down the source of dust, etc., in order to reduce the PM2.5 concentration to a safe level.

7. Regular maintenance and calibration: To ensure the accuracy and reliability of the sensors, PM2.5 sensors should be maintained and calibrated regularly.

Through the above steps, PM2.5 sensors can provide real-time and accurate particulate concentration data in chemical plant dust monitoring, helping chemical plant management to effectively control dust pollution, protect workers' health, and ensure that the production process meets environmental requirements.

PM2.5 sensor installation location and height:

The location and height of the PM2.5 sensor are critical to the accuracy of the monitoring results. Below are some recommendations for PM2.5 sensor installation location and height:

1. Installation location:

1. 1 Workshop entrance: installing a PM2.5 sensor at the entrance of the workshop can help to monitor particulate matter carried by staff and materials as they enter the workshop.

1. 2 Raw material processing area: In the raw material processing area of a chemical plant, such as coal crushing, fertiliser raw material grinding, etc., a large amount of dust will be generated.PM2.5 sensors can be installed near the crusher, grinder and other equipment to monitor the dust concentration in real time, and adjust the equipment's working parameters through the control system in order to reduce the generation of dust.

1.3 Reactor area: in the process of chemical reaction, dust containing harmful substances may be generated.PM2.5 sensors can be installed near the reactor to monitor the generation and emission of dust and ensure that the emission meets the environmental standards.

1.4 Finished Product Handling Area: In the finished product handling area of a chemical plant, such as mixing and drying of pharmaceuticals, dust will also be generated.PM2.5 sensors can be installed in the finished product handling area to monitor the dust concentration and protect the health of the staff.

1.5 Warehouse and logistics areas: in the warehouse and logistics areas of a chemical plant, the handling of materials, loading and unloading and other operations generate dust. the PM2.5 sensor can be installed in these areas to monitor the dust concentration and adjust the ventilation equipment through the control system to minimise the impact of dust on the air quality.

1.6 Emission monitoring: Emissions from chemical plants may contain PM2.5 particulate matter. PM2.5 sensors can be installed near the emission outlets to monitor the concentration of particulate matter in the emissions and ensure that the emissions comply with national and local environmental regulations.

1.7 Office area: PM2.5 sensors can be installed in office areas to monitor indoor air quality and protect employee health.

1.8 Outdoor environment: in the outdoor environment, the sensor can be installed more than 1.5 metres above the ground to avoid the influence of ground dust.

2. Installation height:

    It is generally recommended to install the PM2.5 sensor at a height of 1.5 metres to 3 metres above the ground. This height range can avoid the influence of ground dust and people walking around, and at the same time can capture airborne particles.

    For indoor environments, sensors can be installed near the ceiling to ensure that air quality is captured throughout the room.

    In specific environments, such as chemical companies or flour mills, the height of the sensor can be adjusted to ensure that the monitoring data is closest to the particulate concentration in the actual working environment.

It should be noted that the installation position and height of the PM2.5 sensor should be adjusted according to the specific working environment and monitoring purpose. Before installation, it is recommended to refer to the sensor's technical manual and expertise to ensure optimal monitoring.

In chemical plant application cases, PM2.5 sensors not only provide real-time and accurate dust concentration data, but also help chemical plants to identify and solve dust pollution problems in a timely manner, improve the safety and comfort of the production environment, and reduce hazards to workers' health.
