Description

technical field [0001] The invention relates to the technical field of chemical testing equipment, in particular to a tube furnace testing device capable of dynamically collecting metal vapor. Background technique [0002] Solid fuels such as coal, garbage, and biomass usually contain semi-volatile metal elements such as Pb, Cd, Zn, Cu, Na, and K. Under the high temperature conditions of combustion, gasification or pyrolysis, some or all of these metal elements volatilize to form metal vapor, then leave the furnace with the flue gas, and then pass through the heat exchanger and then condense as the temperature of the flue gas decreases, and are easily enriched in submicron particles or even ultrafine particles. These fine particles are difficult to be efficiently captured by dust removal equipment. The heavy metal elements in them are the main source of the toxicity of the particles, and the alkali metal elements are one of the main matrices that make up the particles, whic...
