Abstract

The present invention provides a boiler flue gas recovery device, and belongs to the field of waste gas treatment equipment. The boiler flue gas recovery device comprises a heat absorber, an absorption tower, a nitrogen and sulfur recovery device, a condenser and a heat converter. An input end of the heat absorber is connected with a waste gas inlet; a waste gas outlet of the heat absorber is connected with the absorption tower; the heat absorber is connected with a hot water outlet of the heat converter; an input end of the condenser is connected with a gas outlet end of the absorption tower; a warm water outlet of the condenser is connected with the heat converter. A gas condensation outlet of the condenser is connected with the absorption tower. A nitrogen-sulfur mixed liquid inlet of the nitrogen and sulfur recovery device is connected with the absorption tower; a nitrogen-sulfur mixed liquid outlet of the nitrogen and sulfur recovery device is connected with the heat converter; and an upper accumulated liquid outlet of the heat converter is connected with the absorption tower.

Description

technical field [0001] The invention relates to the field of waste treatment devices, in particular to boiler flue gas recovery equipment. Background technique [0002] Industrial boilers are currently the main thermal power equipment in my country, and one of the main reasons for the high energy consumption and high pollution during the operation of the boilers is the flue gas emissions from the boilers; On the one hand, it is the direct pollution of flue gas pollutants. At present, there are about 550,000 coal-fired industrial boilers and kilns in China, and the coal consumption accounts for about 1 / 3 of the total annual coal consumption in the country. Problems such as high exhaust gas temperature and high concentration of smoke and dust lead to low boiler operation efficiency and insufficient output. The exhaust heat loss of industrial boilers in my country accounts for 8% to 20% of the heat delivered to boilers. Generally speaking, the design thermal efficiency of cha...
