Flue gas after acid is excluded by chimney.
The Biohazard Waste combustion product gases processing system of the present embodiment passes through the air heat exchanger and two of two series connection
The high-temperature flue gas (850 DEG C～1100 DEG C) out from dual firing chamber can rapidly be cooled down by the flash cold column of individual series connection
To less than 200 DEG C (180 DEG C about), thus accelerating whole fume treatment flow process, improve treatment effeciency.
As shown by the arrows in Figure 1, flue-gas temperature after two air heat exchangers for dual firing chamber's high-temperature flue gas out
Generally at 600 DEG C～800 DEG C.In order to remove the sour gas in flue gas, it is provided with dry type extracting tower 4 and wet
Formula extracting tower 8, dry type extracting tower 4 is arranged between the first flash cold column 3 and the second flash cold column 5, and dry type takes off
The principle of acid is quantitatively to spray into active lime powder in dry type extracting tower 4, make sour gas in flue gas with than
The huge pulverized limestone contact concurrently biochemical reaction of surface area, thus reach deacidification purpose.First can be controlled
The rate of cooling of flash cold column 3 so that temperature after cooling below 600 DEG C (such as：500～600 DEG C), that is, do
Formula deacidification needs a temperature range.After dry type deacidification, the second flash cold column 5 continues cooling, by flue gas cool-down
To less than 200 DEG C, so both ensured that flue gas avoided 200 DEG C～500 DEG C intervals (humidity province that dioxin produces
