Technical Field

The invention relates to the technical field of waste incineration, in particular to waste gas desulfurization equipment for waste incineration.

Background

Along with the waste that produces in people's life is more and more, and most rubbish is concentrated in the msw incineration factory for burn the electricity generation and heat domestic water, the rubbish can generate the flue gas in burning the in-process, and the sulphide in the flue gas is the pollutant that causes main destruction to air and environment, and then needs purify this type of sulphide that contains.

At present, the purification of the sulfide in the flue gas is mostly carried out through the desulfurizing tower, but because the contact range of a chemical reaction fog layer in the desulfurizing tower and the flue gas is smaller, the purification of the sulfide in the flue gas is incomplete, part of the unpurified flue gas is discharged, air pollution is caused, reactants generated after the chemical reaction fog layer reacts with the flue gas cannot be fully recovered, the purified flue gas is easily discharged, and secondary pollution is caused to the air.

Based on the above, the invention designs the waste gas desulfurization equipment for waste incineration.
