Embodiment 1

[0032] Example 1: Determined to sample breathing ambient air:

[0033] Connect the top of the tripod to the quick connector of the lower plate of the cutting complement frame of the particle cutting and trapping device, adjust the tripod to bring the cutting head to the required sampling height; connect the suction nozzle of the particle cutting and trapping device to the host through the connecting pipe The flow controller of the box; set the intake flow value under the sampling temperature and pressure from the main box, and start the sampling switch for sampling;

[0034] The sampling air containing particles enters the cutting head through the inlet of the cutting head, the cutter cuts off the unnecessary particles, enters the filter membrane holder through the cutting and trapping frame hanging tube, and is further intercepted by the filter membrane. When enough particles containing particles are collected After the gas is sampled, sufficient particles have accumulated on...

Embodiment 2

[0035] Embodiment 2: for sampling the air at the source of pollution:

[0036]Connect the air inlet of the flue gas preprocessor to the exhaust pipe of the pollution source; connect the air outlet of the flue gas preprocessor to the air inlet of the cutting head of the particle cutting and trapping device, and set a state tester at the air inlet, and Connect the temperature sensor and pressure sensor of the state tester to the main box through signal wires; connect the suction nozzle of the particle cutting and trapping device to the flow controller of the main box through the connecting pipe; set the sampling temperature and pressure from the main box Start the sampling switch to sample the lower intake flow value; the main box detects the temperature and pressure signals collected from the pollution source, and adjusts the intake flow according to the deviation from the set value.

[0037] The sampled flue gas is initially filtered by the filter in the air intake nozzle, and...

Embodiment 3

[0039] Embodiment 3: for sampling the ground dust fall air:

[0040] Connect the open-source air suction nozzle of the landfall particulate matter sampling device to the air inlet of the cutting head of the particle cutting and trapping device through a connecting pipe, and set a state tester at the air inlet, and separate the temperature sensor and the pressure sensor of the state tester Connect with the main box through the signal line; connect the suction nozzle of the particle cutting and trapping device to the flow controller of the main box through the connecting pipe; set the intake flow value under the sampling temperature and pressure from the main box, start the sampling switch to carry out Sampling; the main box detects the temperature and pressure signals collected from the pollution source, and adjusts the intake flow according to the deviation from the set value.

[0041] When sampling, push the telescopic rod to slide along the ground. During the sliding process...

Abstract

The invention provides an air pollutant source apportionment sampling system and an air pollutant source apportionment sampling method. The system comprises a mainframe box, a particulate matter cutting and complementing device, a fume preprocessor, a ground settlement particle sampling device, a triangle bracket and a connecting pipe, wherein the mainframe box is provided with a flow controller. A co-sampling mode is provided for the source apportionment of a plurality of sampling environments, and an apparatus and a sampling method capable of acquiring particulate matter sample in a constant emission source, in air and on the ground are provided by the invention; the system and the method are extremely wide in application, high in sampling efficiency and capable of providing powerful support for the analysis of pollutant component and content.

Description

technical field [0001] The invention relates to the field of air sampling and analysis and processing instruments, in particular to an air pollutant source analysis sampling system. Background technique [0002] Source apportionment sampling of air pollutants is an important means of environmental detection. At present, there are independent sampling instruments for ambient air and fixed emission sources, but there is no sampling equipment for land subsidence. This method of sampling only for one pollution source has the following disadvantages: 1: The scope of application is narrow. If you want to collect samples of particulate matter from a fixed emission source, the air, and the ground for a polluted area, the type of instrument you need 2: The filter membrane resistance used for source apportionment is generally very large, and the negative pressure capacity of conventional samplers is too small to be fully applicable; 3: When collecting fixed emission sources and minin...
