LEAD PASTE AMMONIUM DESULPHURIZATION SYSTEM

The lead paste which from breaking and separation machine are as raw material for desulphurization. The process is shown in below:

The paste pumped into desulphurization tank A, add the desulfurizer (ammonium bicarbonate) to conduct desulfurization reaction, the mixed liquid of lead paste will be returned to desulphurization tank after compulsory desulphurization in the same time.

After the reaction, the liquid and solid are separated by the filter press. The lead cake (desulphurization lead paste) is entered into the smelting system. The filtrate (desulphurization filtrate A) will be entered into filtrate tank A.

The desulphurization filtrate A will be entered into desulphurization tank B, added lead paste and ammonium bicarbonate to conduct desulphurization reaction. The mixed liquid of lead paste will be returned to desulphurization tank after compulsory desulphurization in the same time.

After the reaction, the liquid and solid are separated by the filter press. The lead cake (desulphurization lead paste) is entered into the smelting system. The filtrate B (desulphurization filtrate B) will be entered into filtrate tank B. The filtrate B (ammonium sulfate) will be entered into purification system.

Technical index
  • The sulfur content of paste after desulphurization<1%
  • The moisture content of paste after filter press<13%
  • System control: Centralized PLC control
