METHOD FOR DETERMINING CONTROL LINE OF WHITE SMOKE PLUME AFTER WET DESULPHURIZATION

摘要

A method for determining a control line of white smoke plume after wet desulphurization, belonging to the field of smoke purification. The method comprises the steps of drawing a saturated air enthalpy humidity curve or an equivalent curve; then acquiring data of temperature and humidity changing with time of a city or a region year by year, and acquiring at least one piece of data each day; drawing the data acquired in the previous step in the obtained saturated air enthalpy humidity curve; and making a tangent line from a saturation line of each weather point in the acquired diagram, wherein a white stripping control region is arranged at a right lower side of the tangent line, white stripping superior to the characteristic of the weather point can be achieved when smoke is adjusted to the region, a region encircled by a white stripping control line and the saturation line at a low-temperature side forms a white stripping day control region, and points falling into the region are days when white smoke is generated.
