Abstract

The invention discloses a system and a method for reducing escape of spent coke in an active coke adsorption tower. According to the system, an adsorption device and a heating device are arranged on an outlet flue of an existing active coke adsorption tower; the heating device is arranged outside the adsorption device; an activated carbon fiber felt layer is used for filtering escaped spent coke particles, felt layer resistance is small, and filtering efficiency is high; and thermal decomposition of the spent coke particles is realized by adopting a heating mode, and the problem that ultra-low emission dust is easy to exceed a standard in an active coke removal technology is solved on line. The method has the advantages of simple structure, low operation cost, easiness in engineering implementation and the like, and has wide application prospects in the aspect of spent coke escape control of the active coke adsorption tower. The system is simple in structure, can be used for modifying and upgrading the existing adsorption tower, and is convenient for engineering implementation.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification, and in particular relates to a system and method for reducing coke escape from an activated coke adsorption tower. Background technique [0002] SO in flue gas 2 NOx emissions are still the main environmental problems, and there is also a certain correlation between the frequent haze weather and the sulfate and nitrate aerosols formed in the atmosphere in recent years. In the power industry, most units have completed ultra-low emission transformation, while in the non-power industry, such as steel, coking, cement, waste incineration and other industries, there is also an urgent need to solve the problem of pollutant removal. [0003] Activated coke is a porous carbon material produced from coal as the main raw material. As a dry removal technology, activated coke combined removal technology has the advantages of integrated desulfurization, denitrification, heavy metal removal, and ...
