The invention relates to the field of desulfurization and dust removal, in particular to a spraying foam desulfurization and dust remover, which comprises a tank body structure, a
water treatment structure, a filtering structure, a dust removal structure, a flow limiting structure and a foam blocking structure. In the dust remover, the filtering structure can be used for storing and precipitatingsewage discharged by the dust removal structure, impurities in the
sewage are precipitated and filtered to be changed into reusable water again to be used by the dust removal structure, so that use ofthe water by the dust removal structure is effectively reduced, meanwhile, the filtering structure can reduce the flow speed of the
sewage discharged by the dust removal structure, which facilitatesfiltration and
precipitation of the
sewage; furthermore, due to the foam blocking structure, residual foam is prevented from entering a pipeline of the
water treatment structure to cause unclean ascending water, so that the dust removal effect of the dust removal structure is reduced, and meanwhile, the foam blocking structure can
delay the flow speed of the water to enable the water to be settledmore completely in the filtering structure; in addition, by using the flow limiting structure, the water inlet amount can be automatically adjusted by controlling the flow speed of the entering gas,so that the dust removal effect of the dust removal structure is better.
