Industrial flue gas particulate matter sampling analysis system and method

Abstract

The invention discloses an industrial flue gas particulate matter sampling analysis system and method, and relates to the field of flue gas sampling equipment. The system comprises sampling equipment, diameter analysis equipment and component analysis equipment. The sampling equipment is used for collecting particulate matter in flue gas discharged through a flue. The diameter analysis equipment is used for measuring the diameter of the collected particulate matters, and the component analysis equipment is used for analyzing the components of the collected particulate matters. The system has the advantages that the collected particulate matters can be qualitatively and quantitatively analyzed, so that the reason for dust emission exceeding the standard can be quickly found out, and a coping scheme can be conveniently taken.

Description

technical field [0001] The invention relates to the field of flue gas sampling equipment, in particular to a system and method for sampling and analyzing industrial flue gas particulate matter. Background technique [0002] Now industrial coal-fired power plants, biomass power plants, waste incineration sludge incineration power plants, etc. must operate normally, and the discharge of dust particles must be qualified. At present, the dust removal technologies at home and abroad mainly include cyclone dust removal, bag dust removal, electric dust removal, electric bag dust removal, and particle bed filter dust removal. , porous inorganic membrane filtration and some other dust removal methods, but there are cases of excessive emissions. At present, the problem of excessive emission in the working conditions is basically caused by phosphor powder leakage detection step by step. For example, the patent CN207280695U discloses a leak detection device for a tube-bundle flue gas he...

Problems solved by technology

[0002] Now industrial coal-fired power plants, biomass power plants, waste incineration sludge incineration power plants, etc. must operate normally, and the discharge of dust particles must be qualified. At present, the dust removal technologies at home and abroad mainly include cyclone dust removal, bag dust removal, electric dust removal, electric bag dust removal, and particle bed filter dust removal. , porous inorganic membrane filtration and some other dust removal methods, but there are cases where the discharge exceeds the standard

At present, the problem of excessive emission in the working conditions is basically caused by phosphor powder leakage detection step by step. For example, the patent CN207280695U discloses a leak detection device for a tube-bundle flue gas heat exchanger, including a material tank and a fluorescent lamp. The bottom of the material tank is equipped with a hollow Base, at least one gas nozzle is set on the upper end of the base, a power supply is provided inside the base, a foot switch is provided beside the base, the foot switch is connected to the gas nozzle and the power supply through a wire, the power supply is connected to a fluorescent lamp through a wire, and a pipe is arranged on the top of the barrel. There is a cover on the upper end of the pipe, which can be sprayed with phosphor powder. Leakage points can be checked by detecting phosphor powder. The method of phosphor powder leak detection is time-consuming and the root cause may not be found

There is equipment to detect dust concentration in the market, but the sampling volume is too small to analyze the sample, only the concentration can be measured
