Embodiment 1

[0060] Use the moisture content sampling tube to connect the desiccant, and then connect the sampler host;

[0061] Put the moisture content sampling pipe into the flue, start the main engine, and measure the moisture content of the flue gas in the flue to be 5.7%.

[0062] Connect the multifunctional sampling tube, Anderson eight-stage sampler, quartz fiber filter cartridge, condensation unit, drying unit and sampler host through PVC hoses to ensure the airtightness of the device as a whole; The gas port is connected by a conical funnel;

[0063] The thin tube end of the tapered funnel is connected to the inner tube of the multifunctional sampling tube. The diameter of the air inlet of the Anderson eight-stage sampler is the same as the diameter of the inner tube of the multifunctional sampling tube.

[0064] Insert the multifunctional sampling tube into the flue, measure the flow rate of the flue gas at 18.7L / min, and the temperature at 120°C, and pass the collected flue ga...

Abstract

The invention provides a sampling apparatus and a sampling method for simultaneous collection of exhaust gas pollution source size-fractionated particles and gas phase organic matters. The sampling apparatus comprises the following components: a multifunctional sampling pipe which is connected to a flue; an Andersen fractionation sampler which is connected to the multifunctional sampler, wherein the diameter of an air intake of the Andersen fractionation sampler and the diameter of an inner pipe of the multifunctional sampling pipe are identical; an outlet end of the Andersen fractionation sampler which is connected to a quartz fiber filter membrane cylinder; a condensation unit which is connected to an outlet end of the quartz fiber filter membrane cylinder; an ion exchange adsorption resin unit which is connected to an outlet of the condensation unit; a drying unit which is connected to the ion exchange adsorption resin unit; and a sampling instrument host which is connected to the drying unit. The sampling apparatus can be used for simultaneously collecting the exhaust gas pollution source size-fractionated particles and the gas phase organic matters; equipment in the sampling apparatus has the advantages of easy connection, easy operation, simple and easy sampling, good effects, high accuracy, and environmental and social dual benefits.

Description

technical field [0001] The invention relates to the technical field of flue gas sampling, in particular to a sampling device and a sampling method for simultaneously collecting classified particles of waste gas pollution sources and gas-phase organic matter. Background technique [0002] In recent years, the problem of environmental pollution caused by coal combustion in my country has become increasingly prominent, and has become a major issue affecting the national economy and people's livelihood. During the combustion of raw coal in the boiler, the coal structure molecules will undergo various chemical reactions and produce a variety of pollutants, which have a relatively large impact on human health and the ecological environment. x , SO x , radioactive particles, heavy metals and polycyclic aromatic hydrocarbons, etc. At present, my country's coal-fired power plants NO x , SO x There are corresponding national control standards for mercury; and for inhalable particu...
