Abstract

The invention discloses a multi-stage temperature control device for collecting condensable particulate matter, which comprises a sequentially connected multifunctional sampling structure, a sampling gun accompanied by a heating belt, a serpentine condenser tube, a first impact bottle, a second impact bottle, a condensable A particle filtering device and a sampling pump; a first temperature sensor is arranged in the serpentine condenser tube, and a second temperature sensor is arranged in the second impact bottle. The multi-level temperature control device for collecting condensable particulate matter of the present invention improves the collection efficiency of condensable particulate matter CPM from fixed pollution sources through multi-layer temperature control, and can more effectively and accurately capture condensable particulate matter CPM in flue gas. CPM is converted from gaseous state to liquid state and solid state, and removes SO 2 Soluble in water interferes with the mass concentration of CPM to achieve accurate measurement of CPM.

Description

technical field [0001] The invention belongs to the field of collecting condensable particulate matter (CPM) from fixed pollution sources, and in particular relates to a multi-level temperature control device for collecting condensable particulate matter which improves the efficiency of collecting CPM from fixed pollution sources through multi-layer temperature control. Background technique [0002] Foreign scholars have gradually proposed the concept of condensable particulate matter (CPM) in the study of coal-fired flue gas pollution control technology, and the research hotspots change with the actual situation. In the early 1990s, the United States passed the Clean Air Act, which gradually controlled the emissions of conventional pollutants from coal-fired power plants. However, when the denitrification device is put into operation and SO 2 The increase in the concentration of water-soluble ions brought about by deep removal has gradually attracted the attention of resea...
