Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0028] Such as figure 1 As shown, a low-sulfur flue gas desulfurization and denitrification device provided by an embodiment of the present invention includes an adsorption tower 1, a vibrating screen 2, a conveying mechanism 3, a recovery vehicle 4, a buffer bin 5, and a feeding bin 6, wherein:

[0029] The conveying bin 6 provides fresh activated carbon for the entire desulfurization and denitrification device. The fresh activated carbon or the activated carbon separated by the vibrating screen 2 and can be directly recycled is transported to the adsorption tower 1 through the conveying mechanism 3 for desulfurization and denitrification purification treatment. The desulfurization and denitrification device provided by the invention does not rely on the analysis process, and has a simple process, ...

Abstract

The invention belongs to the technical field of flue gas purification equipment and discloses a low-sulfur flue gas desulfurization and denitrification apparatus, comprising an adsorbing column and avibrating screen; the adsorbing column is provided with a first region, a second region and a third region sequentially along a flow gas circulation direction; the first region is provided with a fluegas incoming port and an ammonia spray grille arranged at the flue gas inlet; the third region is provided with a flue gas outlet; the second region is provided with a mobile activated carbon layer inside; the activated carbon layer flows in from a top inlet of the adsorbing column and flows out of a bottom outlet; the vibrating screen is connected with the bottom outlet of the adsorbing column and is connected with the top inlet of the adsorbing column through a delivery mechanism. The low-sulfur flue gas desulfurization and denitrification apparatus has the main advantages that an activatedcarbon resolution device is provided, the adsorbing column structure is selectively designed according to the characteristics of flue gas, activated carbon suitable for direct reuse is screened and separated in conjunction with the vibrating screen, efficient deep denitrification is provided for the flue gas with relatively low content of sulfur, no dependence on resolution procedures occurs, theprocess is simple, the controllability is high, and great convenience and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of flue gas purification equipment, in particular to a low-sulfur flue gas desulfurization and denitrification device. Background technique [0002] Activated carbon flue gas desulfurization and denitrification technology has begun to take shape in the steel industry. This technology can not only remove SO in flue gas at the same time X and NO X , also has the advantages of no water consumption, no secondary pollution, effective removal of pollutants such as dust and heavy metals (such as mercury) in the flue gas, and the ability to regenerate sulfur resources through adsorbent regeneration, etc., which can be well applied to flue gas Purification and governance. [0003] An activated carbon flue gas purification device (the publication number is CN106693603A) discloses that the device mainly includes an activated carbon adsorption tower and a desorption tower. 3 parts (upper, lower part and intermediate ...
