Embodiment Construction
[0024] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0025] combine Figure 1-2 , the present invention mainly includes a pollutant adsorption device 5 , a waste heat recovery system (WHR) 4 , a washing tower 6 , an air bottle 15 and a NO oxidation device 11 . Utilize pollutant adsorption device 5 to NO and SO in waste gas 2 For enrichment, the adsorbent includes molecular sieve, Al 2 o 3 and so on for NO and SO 2 substances to be adsorbed. Utilize Na 2 SO 3 The solution and the washing waste liquid produced by desulfurization are used together as the washing liquid for denitrification, realizing the transformation of waste into treasure. The NO is oxidized by intermittently working ultraviolet rays and the air supplied by the air bottle, and the oxidation rate is relatively high. Use the waste heat recovery system (WHR) to reduce the temperature of the exhaust gas, and use the adsorbent to remove NO and SO ...
