Embodiment Construction

[0070] The present invention will be further described below in conjunction with the accompanying drawings and examples. It should be understood that the following examples are intended to facilitate the understanding of the present invention, and have no limiting effect on it.

[0071] The on-site detection device for air pollutants emitted by civil solid fuel combustion of the present invention comprises a flue gas intake part, a dilution air part, a dilution mixing part and a sampling part.

[0072] Such as figure 1As shown, the flue gas inlet part is composed of an impact particle separator 101, a heating sampling pipe 102 and a flow meter I103. Among them, the impact particle separator 101 adopts a self-designed impact structure. Its air intake end extends into the flue, and the air intake end is equipped with a sampling nozzle to meet the air flow sampling. The air flow is smooth, which can reduce the loss of particulate matter and is used to remove smoke. Large particl...

Abstract

The invention discloses a civil solid fuel combustion atmospheric pollutant emission field detection device which is characterized by comprising a flue gas inlet part, a dilution air part, a dilutionmixing part and a sampling part. The civil solid fuel combustion atmospheric pollutant emission field detection device can measure the emission concentration of civil solid fuel combustion particles and gases such as CO2, CO, SO2 and NOx, and can accurately determine an emission factor thereof. In addition, the civil solid fuel combustion atmospheric pollutant emission field detection device has the advantages of compact structure, simplified system and the like, and is suitable for field application.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and relates to an on-site detection device for civil solid fuel combustion air pollutant discharge. Background technique [0002] Civilian solid fuel combustion is an important source of air pollution in my country. It is estimated that in 2017, SO 2 , NO x , CO and PM 2.5 They accounted for 23%, 3.6%, 42% and 39% of their total emissions respectively, but their emissions have large uncertainties. In addition to the large uncertainty of activity levels, the uncertainties of emission factors are also quite large. large, and sampling is an important factor affecting the uncertainty of emission factors. Emission factor refers to the amount of pollutants discharged by a unit of activity, and is an important parameter for establishing an air pollutant emission inventory; the emission inventory refers to the emission of various pollutants from a certain range of pollutant sources to...
