The invention discloses a multielement material collaborative gasification method and
system. The method comprises the steps of 1, pretreatment, wherein pretreatment is conducted on
organic fluid waste, so that filter cakes are obtained; 2,
drying for
powder production, wherein
rotational flow heat exchange is conducted between the filter cakes and heat carrying gas, and meanwhile, crushing impacttreatment is conducted on the filter cakes, so that
powder waste is obtained; 3, gas-
solid separation, wherein the
powder waste and
tail gas are separated; 4, gasification of
slag, wherein collaborative gasification treatment is conducted on the powder waste and additional
solid waste, so that synthesis gas and the
slag are obtained; 5, aftertreatment of the synthesis gas, wherein
waste heat recovery is conducted on the synthesis gas in the first place, and then purification treatment is conducted, so that purified gas and waste water are obtained; 6, aftertreatment of the
slag, wherein chilling treatment is conducted on the slag, so that a glassy-state slag material is obtained; and 7, treatment of the waste water. By means of the multielement material collaborative gasification method,
drying treatment can be conducted on the
organic fluid waste, and the fluid-form waste is produced into a powder
waste material; the powder
waste material can serve as a
raw material of the gasification slag; and collaborative gasification treatment of the multielement materials, namely the
solid waste and the
organic fluid waste, is achieved.
