Sampling device of combustion flue gas samples containing high concentration particulate matters

Abstract

The invention aims at solving the problem of incapability of obtaining particulate matter samples and pure flue gas from high dust flue gas simultaneously in the prior art to provide a sampling deviceof combustion flue gas samples containing high concentration particulate matters. The technical scheme of the invention is that the sampling device of the combustion flue gas samples containing the high concentration particulate matters comprises a mixer for mixing the original flue gas with liquid and a gas-liquid separator for separating gas of which the particulate matters are removed in the mixer from liquid with the particulate matters, wherein the mixer comprises a liquid jet pump and a mixing box, the inlet of the gas-liquid separator is connected with the outlet of the mixing box through a pipeline, the gas-liquid separator is further provided with a flue gas sample outlet and a wastewater outlet. The sampling device of the combustion flue gas samples containing the high concentration particulate matters disclosed by the invention not only can sample the particulate matters in the flue gas and the flue gas at the same time, but also is simple in structure and low in cost.

Description

technical field [0001] The invention belongs to the fields of energy and environmental protection, combustion flue gas and environmental monitoring, and relates to a combustion flue gas sample sampling device containing high-concentration particles. Background technique [0002] According to the current domestic waste disposal methods, most of them are treated by incineration. With the enhancement of people's awareness of environmental protection, and the country's higher and higher requirements for environmental quality, the control technology of exhaust gas has been paid more and more attention. The early treatment technology is to use flue gas purification equipment to reduce the emission of pollutants, such as electrostatic precipitator, cyclone dust collector, bag filter and other equipment for granular matter; organic matter is treated by incineration, condensation, catalytic oxidation, absorption, adsorption and other methods. Control; acid gas is removed by dry, semi...
