Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiment.

[0020] A boiler flue gas heat recovery equipment, such as figure 1 As shown, it includes a heat absorber 1, an absorption tower 2, a debris recovery device 3, a condensation device 4 and a heat exchanger 5. Mainly through multiple heat absorption, the heat in the exhaust gas is absorbed.

[0021] The input end of the heat absorber 1 is connected to the waste inlet 1.1; the waste outlet 1.3 of the heat absorber 1 is connected to the absorption tower 2; the heat absorber 1 is connected to the warm water outlet 5.1 of the heat converter 5; the The input end of the condensation device 4 is connected with the gas output end of the absorption tower 2 . The warm water outlet 4.4 of the condensation device 4 is connected to the heat exchanger 5; the gas condensation outlet 4.2 of the condensation device 4 is connected to the absorption tower 2. The miscellaneous liquid inlet 3.1 of the sa...

Abstract

The invention provides boiler flue gas heat recycling equipment, and belongs to the field of waste treatment devices. The boiler flue gas heat recycling equipment comprises a heat absorber, an absorption tower, an impurity recycler, a condenser and a thermal converter; an input end of the heat absorber is connected with a waste inlet; a waste outlet of the heat absorber is connected with the absorption tower; the heat absorber is connected with a hot water outlet of the thermal converter; an input end of the condenser is connected with a gas output end of the absorption tower; a warm water outlet of the condenser is connected with the thermal converter; a condensed dew outlet of the condenser is connected with the absorption tower; a hybrid liquor inlet of the impurity recycler is connected with the absorption tower; and an upper-layer accumulated liquor outlet of the thermal converter is connected with the absorption tower.

Description

technical field [0001] The invention relates to the field of waste treatment devices, in particular to a boiler flue gas heat recovery device. 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...
