flue gas desulfurization system
Alkaline wet flue gas desulfurization dust removal technology, using in coalfired boiler, furnace, smelting, casting and other governance, flue gas desulfurization technology is mature, reliable and it has convenient installation, maintenance, operationand management, with low operating cost, and high desulfurization efficiency.
Working Principle:
Alkaline wet desulphurization device is the use of spray, self-boiling, gasification absorption, spraying, sieve absorption, dehydration, excreted. The desulphurization equipment is completed by three processes. The device is due to self-excited boiling, to gather highly atomized liquid absorption tower, a foam layer liquid mist capture and efficient absorption of the liquid, gas, solid three-phase mass transfer has been optimized, wet sticky liquid the purification mechanism attached to the residence, collision, absorb two-film theory have been better to play, the purification of flue gas dust and SO2 have a good effect.
The advantages of packed tower type flue gas desulfurization wet scrubber:
1. High desulfurization efficiency can reach more than 95%;
2. Using limestone as absorbent, it's cheap and easy to get rich in natural resources, with a high utilization; Also can use industrial base as absorbent;
3. Mature technology, high reliability of equipment operation, good adaptability to coal, especially suitable for high sulfur coal;
4. Compact equipment design, small land area, using advanced technology and dehydration technology to prevent a fan with water, apply to any of the sulfur coal flue gas desulfurization;
5. Strong adaptability of furnace load change, suitable for all kinds of desulfurization and reconstruction project of coal fired facilities, the equipment is easy to operate, stable running, is one of preferred device of the boiler, furnace, smelting, casting and other equipments for flue gas desulfurization.
