Abstract

The invention relates to a sampling system applicable to low-concentration trioxide sampling. The sampling system comprises a first thermostat water bath, a second thermostat water bath, an ice bath, a gas-washing bottle and an air pump; a first condensing coil is arranged in the first thermostat water bath, a second condensing coil is arranged in the second thermostat water bath, hydrogen peroxide is arranged in the gas-washing bottle, a sulfur trioxide sampling gun is connected to one end of the first condensing coil, an absorption bottle is arranged in the ice bath, isopropanol is arranged in the absorption bottle which is connected with the gas-washing bottle, and the gas-washing bottle is connected with the air pump. The sampling system has the advantages that flue gas is subjected to sampling treatment through the sulfur trioxide sampling gun, the flue gas enters the absorption bottle of the ice bath through condensing treatment of the first thermostat water bath and the second thermostat water bath in sequence, condensation and collection of sulfur trioxide are realized through the isopropanol, the sulfur trioxide in the flue gas can be assuredly condensed and collected as compared with condensation of an existing individual condensing coil, condensing efficiency is improved, and the sulfur trioxide in the flue gas can be completely collected.

Description

technical field [0001] The invention relates to a sampling system suitable for sampling low-concentration sulfur trioxide. Background technique [0002] Sulfur trioxide is a very harmful coal-burning pollutant. Sulfur trioxide is generated in the flue gas of existing coal-fired power plants. The existing sampling device for sulfur trioxide includes a sampling gun and a single condensing coil. Then it is transported to the condensation coil for condensation collection, but the existing sampling device is not suitable for low-concentration sulfur trioxide testing, the test data is inaccurate, and the complete condensation collection of sulfur trioxide in the flue gas cannot be realized, and the sampling gun is easily damaged during the low temperature process. Adsorption of sulfur trioxide by dust particles. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sampling system suitable for sampling low-concentration s...
