冶炼炉脱硫——SDS干法脱硫

Due to the increasing awareness of environmental protection, environmental protection regulations have continuously increased the demand for chemical plant flue gas treatment technologies. Now in our country, the raw materials of the metal products industry are sulfide ores, and the entire smelting process will also produce flue gas containing a large amount of SO2. There is no Efficient desulfurization may seriously pollute the environment and lead to serious consumption of sulfur resources. In order to meet environmental protection regulations, flue gas needs to be rectified.

SDS desulfurization technology consists of adding active calcium desulfurizer to the flue gas, which can convert sulfur dioxide in the flue gas into sulfate when working under normal temperature and pressure or in a pressurized environment. Sulfate can react with active calcium to form calcium bicarbonate to achieve desulfurization. This technology has the advantages of complete technology, simple equipment, flexible operation, and good application effect, and is widely used in the flue gas desulfurization industry.

The technical advantages of SDS dry dethinning are as follows:

1. The equipment is simple and easy to operate. The equipment is small in size and will not be limited by the location. It is convenient and flexible to layout.

2. The overall temperature of desulfurization is reduced, and the temperature of the exhaust system is increased, and there is no problem of whitening.

3. The desulfurization system operates completely dry without discharging sewage.

4. Compared with general desulfurizers, active calcium desulfurizers can reduce the purchase of multiple desulfurizers, reduce multiple filling costs, and reduce multiple harmless treatment costs of solid waste.

5. The desulfurization efficiency is as high as over 95%, it is simple to make, consumes less electricity, and is sturdy and durable.

SDS dry desulfurization is suitable for tail gas treatment of natural gas boilers, coal-fired boilers, waste incinerators, refinery furnaces, coking ovens, porcelain and other furnaces.
