SDL participated in the compilation of the group standard for fugitive particulate matter emission sources in ultra-low emission in iron and steel industry

2025-01-08

The group standards, "Technical guidelines for inventories preparation of fugitive particulate matter emissions sources in ultra-low emission in iron and steel industry" and "Technical requirements for monitoring and surveillance system of fugitive particulate matter emission sources in ultra-low emission in iron and steel industry", in which SDL participated in the compilation, were released and implemented on December 10, 2024. These standards can be used to guide iron and steel enterprises in carrying out tasks such as the treatment of fugitive particulate matter emissions and the assessment and monitoring of ultra-low emissions.

An effective monitoring system is the key to the control of unorganized emissions. The "Technical Guidelines for Ultra-low Emission Retrofits of Iron and Steel Industry" proposes that for unorganized emission monitoring, TSP monitoring facilities should be installed at dust-generating points, and ambient air quality monitoring stations should be set up in the factory area. SDL has a complete integrated solution for online monitoring of unorganized particulate matter emission sources in ultra-low emission in iron and steel enterprises. SDL can provide monitoring equipment such as online dust monitoring systems (TSP), micro air quality monitoring stations, and ambient air quality monitoring stations, supporting comprehensive monitoring of the control effect of unorganized particulate matter emission sources.

Micro Air Quality Monitoring System

▶ Applicable to the monitoring of unorganized emissions at factory boundaries/parks, dust monitoring at construction sites/roads, grid-based monitoring, etc.‍

▶ Adopting sensor technology to measure six air quality parameters and TVOC.

▶ Extraction-type sampling with a stable sampling flow rate ensures the accuracy of monitoring data.

▶ Zero-point calibration function and remote calibration function.

▶ Heating and temperature-control function to adapt to high-humidity weather.

Dust Monitoring System

▶ Applicable to dust monitoring at factory boundaries, construction sites, roads, etc.

▶ Using the light-scattering method to monitor TSP, PM10, and PM2.5, and functions such as noise, meteorological monitoring, and video can be extended.

▶ Equipped with a heating and dehumidifying function to adapt to high-humidity weather.

▶ Linked with dust-suppression equipment such as fog cannons.

▶ Round-the-clock automatic monitoring and will automatically alarm in case of equipment failure.

Ambient Air Particulate Matter Monitoring System

▶ Applicable to the monitoring of particulate matter concentrations at factory boundaries, in parks, at construction sites, on roads, etc.

▶ Adopting the combination of β-ray absorption method and light scattering method, featuring a fast response time.

▶ The shortest detection cycle is 1s, with a high-speed analysis, enabling it to track changes in working conditions.

▶ Strong expandability and optional parameters such as TVOC, NO₂, and CO can be configured.

▶ Easy to operate, supports automatic calibration, and requires little maintenance.

Ambient Air Quality Monitoring System

▶ Applicable to air quality monitoring at factory boundaries and in urban areas.

▶ Using national standard methods to measure SO₂, NOₓ (NO, NO₂), CO, O₃, PM₁₀, and PM₂.₅.

▶ Obtained the certification of new technologies and new products in Beijing.

▶ Independently developed, and has obtained a number of invention and utility model patents.

Ambient Air Non-methane Total Hydrocarbons Monitoring System

▶ Applicable to online monitoring of non-methane total hydrocarbons (NMTHC) concentration in ambient air at factory boundaries.

▶ Two methods are available: direct measurement method and differential subtraction method. In the direct measurement method, NMTHC is measured through enrichment. There is no interference from other substances (O₂, N₂, H₂O), and the detection limit is low.

▶ The achievements of the National Major Scientific Instrument Special Project of the Ministry of Science and Technology are combined with the chromatography technology of ‍‍‍‍‍‍‍‍‍Orthodyne S.A.‍, ensuring high system stability.

▶ Automatic alarm and multi-point automatic quality control.
