The sodium-calcium double alkali method [Na2CO3--Ca(OH)2] uses soda ash to absorb SO2, lime to reduce and regenerate, and the absorbent is recycled after regeneration, without wastewater discharge. Na2CO3 is only a starting alkali. After starting, it actually consumes lime. In theory, no soda ash is consumed (only some will be taken away when cleaning the slag, so there is a small loss). The regenerated NaOH and Na2SO3 and other desulfurizers are recycled.

★Performance characteristics

1. The use of lime as a regeneration agent is safe and reliable, with a wide source and low price.
2. The sodium alkali desulfurization is adopted. Due to the large solubility of sodium alkali, the absorption reaction speed is fast, and it can be regenerated and recycled. Compared with the traditional process, the liquid-gas ratio design can be taken as a small value, which can greatly reduce the operating cost and reduce the construction investment of water pumps and pipelines.
3. The design of sodium alkali regeneration and solid-liquid separation processes is performed outside the tower. The desulfurization absorption tower has no scaling phenomenon, which can ensure the stable operation of the system. The solid-liquid separation device used can not only meet the solid-liquid separation effect, but also reduce the land area, especially in places with small areas.
4. Use CFD (computer flow field simulation) technology to optimize the concentration field, velocity field, and temperature field of the desulfurization tower to ensure that all process parameters meet the working conditions.

★FAQ

Q. How high is the dust removal efficiency of bag filters?
A. The dust removal efficiency can generally reach more than 99%, and can effectively filter fine dust above 0.3 microns.

Q. Can bag filter handle high temperature gas?
A. It can handle high temperature gas up to about 250℃. It needs to use high temperature resistant filter material and control the temperature and humidity of the gas.

Q. How to extend the service life of bag filter?
A. Choose appropriate filter material, clean dust on time, avoid high temperature shock and dust blockage, and perform regular inspection and maintenance.
