Abstract

The invention discloses a calcium-based asorbent double reaction desulphurization method and a system thereof. The system comprises a boiler, a reactor, a dust catcher, a draught fan and a chimney which are sequentially connected. The boiler is connected with an absorbent addition device. The lower part of the dust catcher is connected with a conditioning device. The outlet of the conditioning device is connected with a reactor. The first time desulphurization is carried out in the boiler. And then the second desulphurization is carried out in the reactor. The CaO part generated after the calcium-based asorbent is calcined in the boiler reacts with SO. The other unreacted CaO enters into the reactor and the dust catcher along with the flue gas. The Cao which is unreacted after dust removal enters into the conditioning device, humidified with a conditioning ash containing CaO in the conditioning device; the activity of desulfurating agent is recovered, enters into the reactor and secondly reacts with the SO in the flue gas. The invention not only can increase the utilization rate and the desulphurization efficiency of the desulfurating agent, but also does not need the desulfurating agent to be added in the exterior of the boiler and a desulfurating agent digestive organ, thus reducing the cost.

Description

【Technical field】 [0001] The invention relates to the field of industrial desulfurization, in particular to a calcium-based absorbent double-effect reaction desulfurization method and system. 【technical background】 [0002] At present, there are mainly two ways of industrial desulfurization: in-furnace desulfurization and out-of-furnace flue gas desulfurization. [0003] In-furnace desulfurization is to add a desulfurizer in the furnace. Because the temperature in the furnace is high, it is unfavorable to the desulfurization reaction. The unreacted desulfurizer is discharged with the flue gas and cannot be fully utilized. The consumption cost is high, and the desulfurization efficiency is low. [0004] Flue gas desulfurization outside the furnace is to add a desulfurizer to the flue gas to remove SO x , this method also requires special addition of desulfurizer, and the need to configure a desulfurizer digester, which is costly. 【Content of invention】 [0005] The purpo...
