Resource treatment method for waste incineration fly ash
The invention discloses a resource treatment method for waste incineration fly ash. The resource treatment method comprises the following steps of: forming: forming the waste incineration fly ash into a block mass; distilling: adding the block mass into a distillation tank, and performing heating and distilling under a vacuum condition; condensing: cooling the multiple distilled chlorine salts in a condenser at different temperature sections; absorption: using alkali liquor as a working medium of a vacuum pump to absorb acid gas in vacuum exhaust; and deslagging: discharging residues from a distillation retort to obtain ceramsite. The method has the advantages that the technology of combining catalytic chlorination and vacuum distillation is adopted, and the purpose of resource treatment is achieved while harmlessness of the waste incineration fly ash is achieved.
本发明公开了一种垃圾焚烧飞灰的资源化治理方法，包括如下步骤：成型：将垃圾焚烧飞灰成型为团块；蒸馏：将团块加入蒸馏罐中，在真空条件下加热蒸馏；冷凝：将蒸馏出来的多种氯盐在冷凝器中不同温度段下冷却；吸收：用碱液做为真空泵的工作介质，吸收真空排气中的酸性气体；出渣：从蒸馏罐中放出残渣，得到陶粒。本发明优点在于采用催化氯化与真空蒸馏相结合的技术，在实现垃圾焚烧飞灰无害化的同时，达到资源化治理目的。
