Abstract

The invention provides a sampling unit, apparatus and method for particulate matters in flue gas from civil stove. The sampling apparatus comprises a hard sampling pipe and a sampling hose, wherein the hard sampling pipe is provided with a particulate matter filtering device, the particulate matter filtering device is provided with a heating device and a supporting device, the heating device is used for controlling the temperature in the particulate matter filtering device, and the supporting device is used for keeping the flow direction of the flue gas in a horizontal state. The sampling apparatus is simple in structure, convenient to use and efficient in sampling; the hard sampling pipe is connected with an automatic flue gas sampling instrument through the sampling hose, and the sampling hose is resistant to high temperature, so the automatic flue gas sampling instrument can be effectively prevented from being damaged by high-temperature flue gas; meanwhile, the flow direction of the flue gas and the gas inlet direction of the sampling pipe are in a horizontal state through the supporting device, so reliable guarantee is provided for effective sampling; and the heating device is arranged on the outer side of the particulate matter filtering device, so the temperature in the particulate matter filtering device is controlled, and it is avoided that flue gas moisture is condensed in the particulate matter filtering device, and particulate matter collection effectiveness is affected.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a sampling device, equipment and method for smoke particulate matter of civil stoves. Background technique [0002] Studies have shown that in the entire northern region of my country, the amount of loose coal consumption is hundreds of millions of tons, and almost no pollution control measures have been taken for civilian stoves. The gaseous pollutants after the burning of loose coal are directly discharged into the atmosphere, which is harmful to air quality and human health. The hazards of industrial sources are more direct and obvious than those of industrial sources with the same emission. [0003] How to effectively collect the particulate matter emitted by civil stoves is of great significance to the supervision and inspection of environmental pollution, the development of pollution prevention and control work, and the formulation of air pollutant emission ...
