Abstract

The invention relates to a device and a method for simultaneously testing PM2.5 and coagulated particulate matters discharged by a fixing source. The prior art is short of the device and the method for simultaneously testing PM2.5 and coagulated particulate matters in the smoke discharged by the fixing source. The device comprises a smoke sampling part, a PM2.5 collecting part and a coagulated particulate matter collecting part, wherein a sampling head, a sampling gun, a multi-level striker, a condenser pipe, a first surge flask, a second surge flask, a filter, a third surge flask, a fourth surge flask and a sampling pump are serially connected and formed into a detecting pipeline; the multi-level striker is arranged in a heating chamber; a circulating water pump, the first surge flask and the second surge flask are arranged in a first cooling pond; the third surge flask and the fourth surge flask are arranged in a second cooling pond. The pollutant discharging state of the fixing source is judged by analyzing the smoke component, so that the basis is supplied for the discharging control of the fixing source, the discharging of the fixing source is kept at lower level and the device is beneficial to environmental protection.

Description

technical field [0001] The invention relates to the field of flue gas testing of stationary sources, in particular to a device and method for simultaneously measuring PM2.5 and condensable particulate matter emitted from stationary sources. Background technique [0002] With the development of the economy and the improvement of public awareness of environmental protection, the environmental pollution caused by particulate matter emissions has been highly valued. The new ambient air quality standard "GB3095-2012" was promulgated in 2012 and fully implemented in 2016, which specifies the monitoring and control of particulate matter. Stationary sources are an important source of particulate matter in ambient air. Compared with fugitive emission sources, it is more effective to capture and control particulate matter emitted from stationary sources. [0003] The primary particulate matter emitted by stationary sources can be divided into filterable particulate matter (Filterabl...
