The invention discloses a device and a system for separating SO2 by activated coke. The device comprises a heating type spiral conveying body, wherein the heating type spiral conveying body comprises a sealed casing; two ends of the sealed casing are respectively provided with an activated coke inlet and an activated coke outlet; the inside of the sealed casing is sequentially divided into an activated coke preheating section, an activated coke separating section and an activated coke cooling section; a shaft penetrating through the activated coke preheating section, the activated coke resolving section and the activated coke cooling section and a spiral blade fixed on the shaft are arranged in the sealed casing; the shaft is connected with a driving device through a shaft coupler to realize rotation; the bottom of the cross section of the activated coke separating section is a semicircle shape, and the upper part is an upper convex oval shape. The upper convex oval shape structure of the upper part of the activated coke resolving section is used for gathering SO2 resolving gas; a mode of installing the heating type spiral conveying body in an inclined way is used; the unstable flowing of the activated coke due to pressure fluctuation in a tubular heat exchanger resolving device pipe can be avoided; the plunger piston flow generated under a serious condition can be avoided.
Description
technical field [0001] The invention relates to the field of active coke desulfurization resource utilization, in particular to a kind of active coke thermal analysis SO 2 devices and systems. Background technique [0002] Activated coke flue gas desulfurization technology can recover sulfur in industrial flue gas as a resource. The existing resource recovery process can recover SO 2 It is mainly made into sulfuric acid and ammonium fertilizer, which are mainly used in chemical industry, iron and steel, metallurgy and other industries. This technology belongs to the semi-dry desulfurization method, which can achieve near-zero water consumption and can synergistically remove other pollutants (NOx, heavy metals, etc.). [0003] At present, the active coke used for desulfurization is mainly commercial formed coke or granular coke. After desulfurization of active coke, in order to achieve SO 2 resource utilization, usually adopt vertically arranged tubular heat exchangers (co...
