| titleOfInvention | The method and device of sulphur dioxide production alkaline fertilizer in a kind of recycling furnace gas |
| abstract | The present invention relates to a kind of method and device for recycling sulphur dioxide production alkaline fertilizer in furnace gas, the method is that the tail gas containing sulfur dioxide such as is passed through into the retracting device containing lime stone slurry with the SO 2 tail gas that ardealite is produced as raw material roasting, make the effective recyclings such as sulfur dioxide, dust, water vapour in tail gas, the lime stone slurry containing reaction generation gypsum that will be reclaimed is reclaimed from retracting device, dried, grinding, detection, then dispensing is carried out with potassium feldspar, calcining production alkaline fertilizer is carried out in rotary furnace.The invention further relates to the device of the sulphur dioxide production alkaline fertilizer.The present invention is completely eliminated by raw material of waste phosphogypsum and calcines pollution of the sulfur dioxide gas for producing to environment, more environmental benefits and economic benefit, and remanufacture process is simple can be created, than having more superiority with sulfur dioxide relieving haperacidity in furnace gas. |
