Problems solved by technology
In addition to the health effects of coal-burning particulates, these fine particulates will also spread to distant areas with the airflow, reducing visibility in this area and affecting urban air quality
[0004] At present, there are not only few flue gas particle collection systems designed to truly simulate ordinary household coal combustion, but they all have the following problems: 1) cannot filter out the original particles in the air entering the collection system; 2) the existing The acquisition system is not airtight and cannot count the air volume entering the system, and there is no flue gas collection box, so the dilution factor of the coal-fired flue gas and the temperature of the flue gas cannot be adjusted; 3) There is no condensation system installed, and the temperature of the flue gas entering the sampling instrument difficult to control

The invention relates to an acquisition system for collecting particles of different particle size discharged by fire coal. The acquisition system comprises a flue gas collecting box, a flue gas pipeline, a slide plate with wheels, a civil coal-fired furnace, a blower, a frequency converter, a condenser tube, a temperature sensor, a MCI sampler and a MOUDI sampler. The flue gas collecting box, the flue gas pipeline and the slide plate with wheels are made of stainless steel; the civil coal-fired furnace is put inside the flue gas collecting box; the blower can blow air into the flue gas collecting box to dilute flue gas and provide oxygen for combustion; and the particles in the air are filtered by a filter cloth of 120 meshes at the blower air inlet. The apparatus in the invention avoids the defects that original particles in the air cannot be purified to enter the acquisition system, dilution multiple of fire coal flue gas cannot be calculated and flue gas temperature cannot be adjusted, the original apparatus is not convenient for carrying and condensation enters into sampler flue gas etc. The experiment result shows that the effect of collecting particles of different particle size that are discharged by fire coal is obvious and the sampling operation is simple.
Description
Technical field [0001] The invention relates to a collection and analysis technology of coal-fired particulate matter, in particular to a collection system for capturing coal-fired particulate matter with different particle sizes. Background technique [0002] Particulate matter is currently the primary pollutant in the atmospheric environment of cities in my country. my country's energy consumption is dominated by coal, and the particulate matter produced by coal combustion is the main source of particulate matter in the atmosphere. After coal is burned, its smoke and dust emissions account for about 70% of the total pollutant emissions. The smoke and dust are mainly suspended and transported in the atmosphere in the form of particulate matter. [0003] The hazards of particulate matter emitted by coal combustion to human health are mainly manifested in: carcinogenic, teratogenic, and mutagenic. The main reason is that the fine / ultrafine particulate matter in coal-fired particula...
