What is desulfurization?

Desulfurization is a technical process to remove sulfides (such as sulfur dioxide) produced during combustion by chemical or physical methods. This technology is mainly used for coal burning, industrial production and power generation. The purpose of desulfurization is to reduce the emission of sulfur dioxide, air pollution and acid rain. Desulfurization can achieve the effect of removing sulfide through absorption, oxidation and reduction.

SDS dry desulfurization is an effective flue gas desulfurization technology with high desulfurization efficiency and wide applicability. This paper will focus on the principle and advantages of SDS dry desulfurization to help readers better understand this technology.

The principle of 1 SDS dry desulfurization

SDS dry desulfurization uses adsorbents to adsorb sulfur dioxide (SO2) in flue gas, and converts SO2 into solid products such as sulfate or calcium bisulfate through a series of chemical reactions. It mainly includes the following steps:

Firstly, the flue gas is removed by bag filter to ensure the smooth progress of the subsequent reaction.

Secondly, the pretreated flue gas enters the dry desulfurization system. Under the action of the adsorbent, SO2 reacts with the active sites on the surface of the adsorbent and is adsorbed on the adsorbent.

Then, the sealing equipment maintains the relative stability of dry desulfurization process to prevent external humidity from affecting the adsorbent.

Finally, with the adsorption of SO2, the adsorbent is gradually saturated and needs to be regenerated regularly. In the regeneration process, the adsorbent is subjected to the action of hot air, and the adsorbed SO2 is transferred to the oxidant medium, and then discharged through the circulation system.

(1) High-efficiency desulfurization: SDS dry desulfurization technology adopts high-activity adsorbent with strong adsorption capacity, which can quickly and effectively reduce SO2 concentration in flue gas.

(2) Wide adaptability: SDS dry desulfurization technology has strong adaptability to the change of SO2 concentration in flue gas and the fluctuation of flue gas load, and can stably maintain the desulfurization effect.

(3) Recycling of resources: Sulfate solid produced in the process of SDS dry desulfurization can be used as a supplement to fertilizer raw materials or other industrial raw materials, so as to achieve the purpose of recycling waste.

(4) Simple operation and maintenance: SDS dry desulfurization system has simple equipment structure and convenient operation and maintenance, which can effectively reduce the operation and maintenance cost.

SDS dry desulfurization technology is a sustainable flue gas treatment technology. Using adsorbents to adsorb and convert SO2 in flue gas can effectively and flexibly reduce SO2 concentration in flue gas and realize resource recycling. This technology has wide adaptability and simple operation and maintenance, which is of great significance to flue gas purification in industrial fields such as coal-fired power plants.
