Description
Technical Field

Background
SO 2 Is colorless and has strong pungent smell, and is dispersed in air 2 Has serious harm to human health and ecological environment, and is one of main atmospheric pollutants which cause the continuous deterioration of air quality. Currently, the desulfurization pathways are respectively pre-combustion, mid-combustion and post-combustion desulfurization (also known as flue gas desulfurization), where flue gas desulfurization is considered to be the most effective control S0 2 The way. The flue gas desulfurization method comprises a dry method, a semi-dry method and a flue gas desulfurization methodWet desulfurizing. The wet desulfurization generally uses a limestone-gypsum method, which is a method used in a large amount in the industry in China, and the method can corrode equipment, cause secondary pollution, produce byproducts and prevent wastewater from being treated. Semi-dry desulfurization is usually performed by spray drying, which requires periodic cleaning of the pipeline, and is costly. The dry desulfurization is most commonly used as active carbon adsorption desulfurization, the method has simple process, can be recycled, hardly generates waste gas, waste water and waste residue, has lower cost, and can adsorb SO on the basis of no water consumption 2 The strong adsorptivity and certain catalytic activity of the activated carbon can also realize the removal of NO, heavy metal, dust and dioxin at the same time, and the recycling of the activated carbon can also be realized through the regeneration process, so that the whole process has NO pollution.

In 1979, the Hubei pine lawn power plant of China introduces an active carbon desulfurization technology for the first time, and uses iodine-containing active carbon as a catalyst to adsorb on a fixed bed, however, the technology cannot be successfully applied due to serious iodine loss.

When materials are accumulated on the belt 16, a first air cylinder 23 is started, and the driving end of the first air cylinder 23 drives a moving block 24 to move, so that the two symmetrical brackets 12 rotate around the rotating shaft 22, the angle of the belt 16 is adjusted, and the materials are poured into the stirring barrel 6;
by starting the fourth driving motor 743, the driving end of the fourth driving motor 743 drives the first rotating shaft 742 and the protruding block 744 to rotate, the protruding block 744 is slidably connected in the connecting block 745, and the connecting block 745 is driven to move up and down when the protruding block 744 rotates, so as to drive the third driving motor 71 and the rotating shaft 72 to move up and down, so that stirring is more uniform.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
