Embodiment Construction

[0022] The structure of the instrument will be described in detail below in conjunction with the accompanying drawings.

[0023] The flue gas dilution mixed multi-channel graded sampler is composed of three parts: the intake part, the flue gas air mixed diluted particulate matter graded sampling part and the exhaust part. The ambient air (12) passes through the airflow regulator in turn through the air compressor (11) 1 (15), compressed air purifier (16), jet nozzle (17) enter the inner barrel (5) of the dilution channel; the flue gas flow (8) also enters the dilution channel through the sampling gun (9) and the flue gas flow inlet pipe (27) The inner barrel (5) of the passage descends and deflects into the outer barrel (26) of the dilution passage in the inner barrel, and the mixed gas flows upward in the outer barrel and enters the PM 10 Cutting head channel (7) and PM 2.5 Cutting head channel (23), at the same time, the particulate matter samples in the specific particle s...

Abstract

The present invention is composed of three parts as air-in graded sampling for deluted particulate of smoke-air mixture and air-out as double channel graded sampling part for deluted particulate of smoke-air mixture consists of delution channel inner barrel, outer barrel, double channels, cutting head and filter. The particulate in different range of particle diameter at various fixed source in organized discharging can be collected so sampler disclosed in the present invention can completely satisfy requirements of monitoring operation.

Description

technical field [0001] The invention relates to a smoke and dust sampler, in particular to a sampler for collecting particulate matter samples in the mixed gas of smoke and ambient air discharged from a fixed source, and belongs to the technical field of environmental monitoring. Background technique [0002] Particles emitted from fixed sources of pollution exist in the form of aerosols and are one of the main sources of particles in the ambient air. Use the flue sampler to obtain particulate matter samples emitted by fixed pollution sources, and study the particle size distribution and chemical composition of particulate matter of different particle sizes, which is useful for monitoring: the degree of pollution of ambient air, the degree of impact on human health, and whether the pollution control measures adopted are appropriate etc. have important practical value. [0003] At present, there are many manufacturers producing flue sampler products in my country, such as Qi...
