Embodiment 1

[0045] This embodiment relates to a dry desulfurization agent production process and the process system used therein.

[0046] The dry desulfurizer involves the following ingredients: calcium-based materials: calcium carbide slag, quicklime; reducing agent: urea, ammonium formate; catalyst: iron powder, copper slag, steel slag; auxiliary agent: fluorine slag.

[0047]The calcium-based material and additives are sent into the material bin 9 according to the ratio, the catalyst is sent into the catalyst bin 10, and the reducing agent is sent into the reducing agent bin 11. After the raw materials in the material bin 9 are measured by a single screw scale, they are sent to the mill 1 for grinding together with the catalyst in the catalyst bin 10 after being weighed by a belt conveyor scale, and the powder is ground to 600 mesh to obtain dry desulfurization Then use the cyclone dust collector 2 to send the ground semi-finished product and the qualified material in the cyclone dust...

Abstract

The invention discloses dry desulfurization agent production process and system. A calcium-based material, a reducing agent, a catalyst and an auxiliary agent are mainly used as raw materials; a milland a mixing and stirring main machine are the main components of the system. The preparation method comprises the following steps: feeding a calcium-based material, a catalyst and an auxiliary agentinto a mill for grinding to obtain a semi-finished product; feeding the semi-finished product and a reducing agent into a mixing and stirring main machine for mixing and stirring the components, thereby obtaining the dry desulfurization agent. By means of the process and system, the problems that in the prior art, a dry desulfurization agent production method is complex; the technical problems ofunstable blanking, insufficient reaction, influence on the desulfurization efficiency and the product quality and the like of the existing dry desulfurization agent are solved; moreover, the high-stability desulfurization and denitrification absorbent can be produced, the desulfurization efficiency is high, secondary pollution is avoided, the production process is simple, and the operability is high.

Description

technical field [0001] The invention relates to a production process and system of a dry desulfurizer, in particular to the production process and system of a dry desulfurizer for cement production, and belongs to the technical field of desulfurizer production. Background technique [0002] Energy plays an irreplaceable and important role in people's production and life. The use of fossil fuel combustion to obtain the energy needed by human beings is one of the main energy acquisition methods for human beings at present, and coal-fired power generation plays an important role in meeting people's power energy needs. Especially in my country, nearly 80% of the electricity supply is realized through coal-fired thermal power generation. However, the combustion of coal emits a large amount of sulfur dioxide (SO 2 ), nitrogen oxides (NO X ) and dust. The long-term discharge of these pollutants in the atmospheric environment leads to extremely serious atmospheric and environmen...
