Technical principle of salt containing organic wastewater incinerator

Using heavy oil and waste solvents as heating media. Add the mixed waste salt containing organic matter generated in the fluidized granulation tower to the rotary roasting furnace for roasting. Gasification and pyrolysis of organic matter in contaminated salt at high temperatures. The inorganic salts after roasting are sent for comprehensive utilization or landfill. The flue gas generated from roasting is incinerated twice in the incinerator, oxidizing the organic matter in the flue gas into CO2, H2O, HCl, and SO2. The high-temperature flue gas generated from incineration is used as a heat source for granulation and drying of wastewater. The moisture in the salt containing wastewater is vaporized in the granulation tower, and organic and inorganic salts are coated on the seed salt to form particles that grow. The contaminated salt particles are discharged to the roasting furnace for treatment. The granulation tail gas is washed in the washing tower after removing most of the salt dust through a cyclone separator, and the salt powder collected by the cyclone separator is returned to the granulation tower as seed crystals. The washing water is preheated while circulating and washing the granulation tail gas, and is continuously sent to the granulation tower for treatment. The tail gas discharged from the washing tower enters the washing tower, removes the carried liquid foam, and is discharged through the chimney.
