The invention relates to the technical field of cremation machines, in particular to a cremation
machine all-dry-method posttreatment
system which is characterized by comprising a
smoke gas and water isolation type
shock cooling device, a
powder spraying device, a dust remover and adsorption equipment. A
processing technology includes the following steps: enabling high-temperature
smoke gas which is generated by a cremation
machine to enter the
smoke gas and water isolation type
shock cooling device for cooling, enabling the smoke gas in a pipeline to be mixed and contact with powdery absorbents which are sprayed by the
powder spraying device through a
powder spraying process, enabling the absorbents to react with
sulfur oxides and acidic materials in the smoke gas to produce powdery
calcium compounds, and enabling the smoke gas to be conducted at least two levels of dust removing through the dust remover,
trapping dust and sparkles in the smoke gas through the dust remover, wherein off gas after dust removing enters the adsorption equipment, residual infinitesimal noxious substances are absorbed by the adsorption equipment, and the off gas is discharged from a
chimney. According to the cremation
machine all-dry-method posttreatment
system, cooling water is recycled, and therefore generation of water of secondary
pollution is completely eliminated. In addition, the cremation machine all-dry-method posttreatment
system has the advantages that blocking is not easy, the equipment cannot easily be corroded, energy is saved, consumption is low, damage to the equipment is small, service life of the equipment is prolonged, environment is protected, and the like.
