Runner.
The beneficial effects of the utility model：By taking aqueous 60% biomass gasifying furnace clinker as an example, in addition to carbon, it there is also about
7% calcium hydroxide and magnesium hydroxide, 2% is potassium carbonate+sodium carbonate and silica, and its PH is more than 12.The utility model will gasify
Stove produces clinker and first delivers to slag filtration device, clinker conducted into slag drying unit after slag filtration device removes partial moisture
In, flue gas caused by gasification furnace is passed through in clinker drying unit, dries clinker, clinker is finally delivered into interim stacking point；Clinker
Cyclic water tank is drained into the moisture collection of slag filtration device abjection, spraying dust removal tower is squeezed into by water circulating pump, dries clinker
Flue gas afterwards enters spraying dust removal tower, and in spraying dust removal tower, acid-base neutralization reaction occurs for recirculated water containing alkali and flue gas, reduces cigarette
Gas sulfur dioxide emissioning concentration, while dust removing effects are reached by spray, final flue gas is discharged by spraying dust removal tower.This practicality is new
Type can realize that biomass gasifying furnace slag for comprehensive utilizes, and both reduce SO 2 from fume discharge, also achieve clinker drying, do
Clinker after dry is aqueous few, carbon containing height, more preferable sale.
