ANALYSIS OF POLLUTION CHARACTERISTICS OF ORGANIC AIR POLLUTANTS IN NEW DRY PROCESS CEMENT PRODUCING

Guoliang Tian

ABSTRACT: Cement industry is a large coal-burning, but also to produce coal-based VOCs is one of the sources. VOCs are one of the important precursors for the formation of fine particles of PM2.5. In order to obtain the pollution characteristics of organic air pollutants in the production of cement industry, in order to ensure the validity of the data. This article select the nearest cement plant in Hebei LuQuanDingXin(A plant) 1 line rotary kiln (clinker production line of 2500 t/ d) and 2-wire rotary kiln line 1 (3000 t / d) and GaoCheng cement (B plant) NSP Rotary Kiln (4000 t / d) as the research object. The organic pollutants emitted from the cement production were detected and the particulate matter in the flue gas was sampled. The organic pollutants in the particulate matter were detected and the characteristics of the organic pollutants in the cement industry were analysed.
