In the environmental protection industry, dust pollution, as one of the main pollutants in the atmospheric environment, directly affects air quality and public health. JuchuangFC-4The Type 1 single gas path dust sampler, with its core technologies of dual gas path independent sampling and high-precision flow control, has become a core equipment in the fields of environmental monitoring, occupational health, and industrial pollution source control, providing reliable data support for environmental decision-making.

1、 Environmental Air Quality Monitoring: Constructing Regional Pollution Atlas

FC-4Type sampler can simultaneously collect dataTSP(Total suspended particulate matter)PM10(inhalable particulate matter) andPM2.5(Fine particulate matter) samples are accurately measured for dust mass concentration using the filter membrane weighing method. Conducted in a provincial capital city'Blue Sky Defense Campaign'The environmental protection department utilizesFC-4Type of equipment for urban areas12Continuous monitoring at each monitoring point72Hourly sampling, discovering the surrounding areas of traffic arteriesPM10Higher concentration than residential areas42%This provides a key basis for optimizing traffic control measures. Its dual gas path design improves the efficiency of balanced sample collection30%Significantly shortened the cycle of multi parameter synchronous monitoring.

2、 Industrial pollution source control: Lock in the source of excessive emissions

For heavy polluting industries such as steel, cement, and chemicals,FC-4The type sampler can be deployed for monitoring in unorganized discharge areas at the factory boundary. In the ultra-low emission renovation project of a certain steel enterprise, technicians passedFC-4Type equipment for sintering heads, blast furnace tapping yards, etc16Sampling was conducted at a certain point, and it was found that3No. blast furnace tapping yardPM10excessive concentration2.1Twice. Based on meteorological parameters such as wind speed and temperature, accurately locate the defects of inadequate sealing of dust removal facilities and guide enterprises to complete them32Repair the air leakage point to reduce the concentration of particulate matter emissions10mg/m³following.

3、 Occupational health protection: safeguarding the respiratory health of workers

In high dust workplaces such as mining and metal smelting,FC-4The type sampler achieves occupational exposure assessment through a respiratory dust pre collector. Its separation efficiency meets the requirements'BMRC'Curve standard, capable of accurately distinguishing diameters≤7.07μmRespiratory dust. Used by a coal mine safety supervision departmentFC-4The type of equipment sampled the underground excavation working face and detected a concentration of respiratory dust reaching3.2mg/m³(Exceeding)8Hourly time weighted average allowable concentration1.5mg/m³）Immediately urge enterprises to upgrade wet rock drilling equipment to reduce the concentration of flour dust during operations68%.

4、 Emergency monitoring response: supporting the handling of sudden environmental incidents

In sudden environmental incidents such as chemical leaks, fires, and explosions,FC-4Aluminum alloy explosion-proof shell andIP54The protection level can adapt to-10℃to+50℃The environment. In a benzene based substance leakage accident in a chemical industrial park, the emergency monitoring team usedFC-4Type of equipment for downwind direction3kmGrid sampling within the range,4Complete within hours28At a certain pointPM10The detection of volatile organic compound attached particles has bought valuable time for delineating the scope of pollution diffusion and developing evacuation plans.

From urban atmospheric grid monitoring to deep treatment of industrial pollution sources, from detection of occupational disease hazards to environmental emergency response,FC-4The single air path dust sampler has become an important tool in the environmental protection industry due to its precise, reliable, and efficient performance characteristics'Data Catcher'Its technical indicators fully comply with the requirements of the "Environmental Air Quality Monitoring Specification", providing solid technical support for winning the battle to defend the blue sky.
