Regarding the desulfurization treatment of boiler exhaust gas
Thread Content
Regarding the issue of desulfurization treatment of boiler exhaust gas, does anyone have any experience in this regard? Please tell me.
The question is too broad, what do you want to know? Regarding flue gas desulfurization, there are many discussion issues in the forum. There are dry and wet methods for boiler flue gas desulfurization. The dry method involves calcium addition in the furnace for desulfurization, the wet method involves granite water film, double alkali method, etc. If the coal used has particularly high sulfur content, several desulfurization methods need to be combined.
To put it too crudely, there are generally wet desulfurization methods, including limestone-gypsum method, ammonia subtraction method, etc.
Haha~~~~The question is indeed a bit general! Here I tell you one: Use a water film dust removal tower and rinse with alkaline water! !
Boiler flue gas desulfurization is mainly done by dry method and wet method. The effect of wet desulfurization is good, but it is troublesome to deal with sulfur-containing water. If hydraulic slag is used, it is recommended to use wet desulfurization.
There are currently three dozen types of sulfur dioxide tail gas treatment, including wet, dry and semi-dry methods. The most mature one is the lime (limestone)-gypsum method, followed by the double subtraction method, the magnesium oxide method, and the zinc oxide method. ； The dry method mainly involves adding calcium in the furnace ； The semi-dry method is mainly a suspended circulating fluidized bed method.
Thank you. I really learned a lot.
