| titleOfInvention | Device for producing ammonium sulfite and by-producing ammonium thiosulfate liquid fertilizer |
| abstract | The utility model discloses a device for producing ammonium sulfite and by-producing ammonium thiosulfate liquid fertilizer, which can put waste sulfur into a sulfur incinerator for combustion to generate flue gas rich in high-concentration sulfur dioxide gas; the flue gas enters a cyclone separation tower for dust removal, the flue gas after dust removal enters a heat exchanger and a washing and purifying tower for treatment, and then enters a primary absorption tower, a secondary absorption tower and a tertiary absorption tower for absorption, and the flue gas is discharged through a sulfur dioxide removal tower and an ammonia removal tower. And (3) separating solid ammonium sulfite from the liquid in the first-stage absorption tower, the second-stage absorption tower and the third-stage absorption tower in a neutralization tank, carrying out a thionation reaction on the residual liquid and circulating liquid of the washing and purifying tower, the sulfur dioxide removing tower and the ammonia removing tower in a liquid fertilizer generation kettle, and finally adjusting the pH value of the liquid in the liquid fertilizer generation kettle by using alkali to obtain the liquid fertilizer. Adopt the utility model discloses the device can obtain high-purity solid ammonium sulfite and byproduct ammonium thiosulfate fertilizer, has good special industrial use and prospect. |
