Core technology

 

1) The original formula of the desulfurization powder in the composite desulfurization technology uses calcium-based oxidant and catalysis to increase the calcium-based reaction activity, accelerate the desulfurization rate, and improve the desulfurization efficiency;

 

2) The composite desulfurization technology uses a combination of powder and water. The addition of water has a catalytic effect on the powder, increases the reactivity, increases the contact area of ​​the reactants, and prolongs the reaction time. The two promote and synergize with each other. ;

 

3) The composite desulfurization technology provides a reliable desulfurization system for SO2 emission requirements based on the characteristics of different stop and start mills, different quality of raw materials, and different amounts of raw materials added in cement plants. Specially customized metering and conveying equipment is used to achieve 1 to Continuous and stable feeding in the range of 100, to ensure seamless switching between large doses and small doses of desulfurization powder in various states of raw mill shutdown / operation and cement kiln.

 

4) The composite desulfurization technology achieves different background emission values ​​below 200 ~ 2000mg / Nm³, and SO2 emissions from different kiln mines. The desulfurization agent is used within 8 minutes to reach the standard, and desulfurization reaches zero within 10 minutes, and the desulfurization efficiency reaches more than 98%;

 

5) The initial investment cost is 1/20 of the wet desulfurization, and the operating cost is 1/2 of other desulfurization technologies. The effect is stable and reliable, and no secondary pollution is generated. It is a feasible technical solution for SO2 emission reduction in the cement industry;

 

6) The composite desulfurization technology has a small floor area (30㎡), a short construction period (25 days), and small equipment power (30kw), which truly achieves high efficiency and low power consumption.
