Problems solved by technology

[0004] At present, the research on black carbon mainly comes from outdoor sampling research, and there are few research reports on black carbon obtained by burning various fuels in the laboratory. The source is single, and there are great limitations in the research and analysis of black carbon produced by the combustion of fuels in different states, especially common fuels in daily life
In addition, there are not many reports on the research methods of obtaining fresh black carbon by burning black carbon in the laboratory and immediately purifying it, which cannot meet the scientific research needs of researchers.

Abstract

The invention relates to a black carbon preparation apparatus and a preparation method, which belong to the field that a solid-liquid dual-purpose fuel used for indoor research is employed for combustion to prepare the black carbon. The black carbon preparation apparatus comprises a fuel burning device, a purifying system, a tail gas processing apparatus, and an electric control automation system;the fuel burning device comprises a liquid fuel burning device and a solid fuel burning device, and the liquid fuel burning device is connected with the solid fuel burning device through a heatproofinsulating pipe. The electric control automation system is connected with a lead, a flue gas concentration sensor, a black carbon concentration measuring instrument, and an induced draught fan to forma control line, and supervision on the whole system is realized through centralized feedback and centralized control. The preparation apparatus and preparation method can be used for the field of theblack carbon research, and are suitable for research occasions that the solid fuel and the liquid fuel are frequently switched, the condition is controllable, and the combustion of the solid fuel andthe liquid fuel can be better realized to obtain a purified black carbon sample. According to the invention, a programmable automatic feedback system is employed for controlling the experiment condition, and the black carbon generation and subsequent purifying operation are integrated and automated.

Description

technical field [0001] The invention relates to a black carbon preparation and purification device, in particular to a device for preparing black carbon by burning solid-liquid dual-purpose fuel for indoor research. Background technique [0002] It is generally believed that black carbon aerosols are fine particles produced by incomplete combustion of carbon-containing substances such as fossil fuels and biomass, with a particle size between 0.01 μm and 1 μm, and are an important part of the atmosphere and PM2.5. [0003] Black carbon has a large amount of emissions in my country, which can reduce visibility, promote the formation of haze weather, and absorb organic matter, heavy metals and secondary pollutants during atmospheric transportation, affecting atmospheric composition and atmospheric chemical processes. At the same time, it itself or its surface Adsorbed pollutants can cause respiratory system, cardiovascular and other diseases, and have adverse effects on human he...
