Abstract

The invention discloses a high-efficient clean utilization system of coal based on activated coke dry method flue gas purification technology. The system comprises a flue gas pipeline, an adsorption and desulfurization tower, and a desorption regenerator; the adsorption and desulfurization tower is provided with a flue gas inlet, a flue gas outlet, an activated coke inlet, and activated coke outlet, wherein the flue gas inlet of the adsorption and desulfurization tower communicates with the flue gas pipeline, and the adsorption and desulfurization tower is used for adsorbing sulfide in the flue gas; and the desorption regenerator is provided with a regenerated activated coke inlet and a regenerated activated coke outlet, the regenerated activated coke outlet of the desorption regenerator communicates with the activated coke inlet of the adsorption and desulfurization tower by a screening machine, and the desorption regenerator is used for desorption and regeneration of the activated coke which is used for adsorption of sulfide. The high-efficient clean utilization system of coal based on activated coke dry method flue gas purification technology can be used for promoting harmonious development of the coal energy industry, and effectively solving contradiction between energy and environment with substantial economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an efficient and clean coal utilization system based on activated coke dry flue gas purification technology. Background technique [0002] my country is a large coal-burning country, and coal accounts for 75% of primary energy, and this energy structure will not change in the short term. Sulfur dioxide emitted by coal burning has caused serious pollution to the atmosphere. The annual loss caused by acid rain due to sulfur dioxide in my country reaches 110 billion yuan, accounting for about 7%-8% of the national economic output. [0003] On the other hand, my country is a country with a large population, a large agricultural country, and a large fertilizer country, and sulfuric acid is an important basic raw material for the production of phosphate fertilizers. However, my country's sulfur resources are relatively scarce, and most of them are hidden in coal combustion. ...
