1. The humidification outside the tower is only 5% higher than the humidification and coolinginside the tower, but the humidification outside the tower has the advantages of simplifying the system process, reducing investment, and reducing the wall sticking inside the tower.www.yrdcarbon.com
2. Activated carbon has a certain effect on the removal of nitrogen oxides. In the test, the high concentration of SOZ in the flue gas affected the removal of NO by activated carbon, and the measured removal rate was about 10%.
3. The removal rate of HCl by activated carbon is up to 50%, but the removal effect of acid gas H and SO3 is not obvious.granular activated carbon for water treatment
In the test, the desulfurization effect of the cloth bag dust remover was tested, and its desulfurization rate was about 9%.
4. Analyze the reasons for the low SOZ and NO removal efficiency of activated carbon in the test 1) ordinary activated carbon is used in the test, which has a low adsorption performance;
(2) Due to the limited test conditions, the low input amount of activated carbon per hour in the test means the selected ACIS is lower.
Although the removal efficiency of the activated carbon on SO2 and NO measured in this test is low, the activated carbon used in circulating fluidized bed flue gas desulfurization and denitration has the advantages of simple and reliable process, low system resistance, stable desulfurization and denitration, good economic and environmental protection, NO secondary pollution and so on.
The adsorption properties of activated carbon fiber or modified activated carbon should be further studied.
Activated carbon desulfurization and denitration technology will be a promising technology for the combined removal of pollutants from coal burning.
