Dust rapid analyzer

The dust rapid analyzer is a portable and highly sensitive on-site detection device designed for real-time monitoring of suspended particulate matter concentration in work environments. It is suitable for industrial workshops, mining tunnels, construction sites, and environmental law enforcement scenarios.

The dust rapid analyzer is available in two forms: wired station and wireless station. It can be used in conjunction with monitoring platform software, cloud technology, network cameras, etc. to achieve remote data transmission and real-time video monitoring. 24-hour outdoor visual continuous monitoring of environmental status. Real time monitoring of multiple parameters including dust, noise, weather, toxic and harmful gases, negative oxygen ions, and video images. Modular customization service, allowing users to freely combine and customize various modules according to their needs. The cloud platform stores massive multidimensional data, which is conducive to statistical analysis and traceability.

The working principle of the dust rapid analyzer mainly includes the following:

Principle of light absorption: A certain volume of dusty air is extracted by an air pump, and the dust is trapped on the filter paper. The light beam passes through the filter paper and shines on the silicon photovoltaic cell. The change in the received illumination of the silicon photovoltaic cell will cause a change in the output current intensity. Within a certain range, the amount of dust retained by the filter paper is linearly related to the output current of the silicon photovoltaic cell, which is converted into dust concentration through the calculation program set in the detector and displayed.

Principle of light scattering: The laser emitted by the laser diode forms a thin layer surface light source through a lens group, and when it is irradiated on the aerosol flowing through the sensor room, scattering occurs. The photodetector detects the scattered light intensity and generates an electrical signal, which is proportional to the mass concentration of the aerosol. Then multiply by the voltage calibration coefficient (obtained by measuring specific concentrations of aerosols) to obtain the dust concentration.

Principle of beta rays: When the beta rays generated by the radioactive source inside the detector pass through dust particles, the dust particles will absorb the beta rays. According to the linear relationship between the amount of beta rays absorbed by dust and the quality of dust, the dust concentration can be calculated and displayed.

Principle of electrostatic induction in communication: When dust particles flow through the probe, dynamic charge induction between them generates a signal. Monitor the standard deviation of the charge signal to determine the disturbance of the AC signal, and determine the dust emission based on the magnitude of the instantaneous disturbance.

The main function of the dust rapid analyzer is:

1. Real time monitoring: The dust analyzer can monitor the concentration of dust in the air in real time, providing accurate data for on-site workers.

2. Explosion prevention: Dust can easily cause explosions at certain concentrations, especially in places such as mines, chemical plants, and grain processing. The dust analyzer monitors the dust concentration in real-time, and once it is found to exceed the standard, measures can be taken in a timely manner to reduce the dust concentration, thereby reducing the risk of explosion.

3. Environmental protection: Dust causes pollution to the environment and affects air quality. By monitoring dust concentration with a dust analyzer, relevant departments and enterprises can take measures to reduce dust emissions and protect the environment.

4. Ensuring health: Excessive dust concentration can pose a threat to human health, such as causing respiratory diseases. The dust analyzer can promptly detect situations where the dust concentration exceeds the standard, and take measures to reduce the dust concentration and ensure people's health.

Application fields:

1. Industrial and mining enterprises: The dust analyzer can be used to monitor the dust concentration at the production site of industrial and mining enterprises, ensuring the safety and hygiene of the production environment.

2. Public places: such as shopping malls, supermarkets, cinemas and other public places, monitoring the concentration of dust in the air through dust meters can ensure public health.

3. Environmental monitoring: Environmental protection departments can use dust meters to monitor dust emissions from various places to ensure environmental quality.
