Abstract

The invention discloses a sampling device for ambient air particles in a closed livestock and poultry house. The sampling device comprises a sampler body, a controller and a power box, wherein a suction pump is arranged at the bottom of the sampler body; a gas inlet is formed at the top of the sampler body; a particle cuter, an electric heating net, a filter film, a differential pressure detection sensor and a gas outlet are sequentially arranged at the lower part of the gas inlet; a suction nozzle of the suction pump is located at the lower part of the differential pressure detection sensor; the controller is arranged outside the sampler body and connected with the differential pressure detection sensor, the suction pump and the electric heating net separately; and the power box is arranged outside the sampler body and connected with the controller, wherein the filter film comprises a first adsorption film layer and a second adsorption film layer which are sequentially arranged. The first adsorption film layer and the second adsorption film layer are adopted by the filter film, so that different particles can be conveniently tested and the adsorption efficiency of the ambient air particles in the closed livestock and poultry house is improved.

Description

technical field [0001] The invention relates to a particulate matter sampling device, in particular to an ambient air particulate matter sampling device in a closed livestock and poultry house. Background technique [0002] Air pollution caused by general PM is generally considered to be the consequence of industrialization and urbanization, and agriculture has not been considered as the main source of air pollution. However, European studies have shown that agriculture may be one of the main sources of air pollution emissions, and PM from livestock and poultry farming is one of the main sources of PM from agriculture, and with the development of livestock and poultry farming, its PM emissions account for will also increase accordingly. PM in livestock and poultry farms has three different manifestations from PM in other man-made sources: the concentration of PM is higher than other indoor environments, it carries odor and polluting gas, and it usually contains a wide varie...
