Abstract
Description
Technical Field
[0001] The present application relates to the technical field of waste incineration, and in particular to an integrated reactor. Background Art
[0002] Waste incineration is a method of high-temperature treatment of waste. Waste incineration usually produces a large amount of exhaust gas. Therefore, the treatment of waste incineration exhaust gas is more critical. The waste incineration exhaust gas treatment includes desulfurization and activated carbon treatment. The two often use separate removal systems, that is, the exhaust gas first enters the desulfurization tower for desulfurization treatment, and then enters the activated carbon treatment through the connecting flue. The use of separate removal systems for desulfurization and activated carbon treatment has problems such as large footprint and high management cost. At the same time, the back pressure of the exhaust gas is large when it passes through the connecting flue, and a booster fan is required to smoothly flow through the connecting flue, thereby further increasing the cost of the removal system. This waste incineration exhaust gas treatment method is a heavy burden for small island countries. Due to their small land area, tight land use, limited finances and other factors, they cannot implement this kind of exhaust gas treatment method with a large footprint and high treatment cost, so it needs to be improved. Summary of the invention

The first spraying layer sprays liquid medicine to react with the exhaust gas, thereby desulfurizing the flue gas. The nozzles of the first spraying layer are staggered to ensure full contact with the flue gas. The desulfurized flue gas is then defogged through the first demisting layer.
