Abstract

The invention discloses a household garbage incineration fly ash demercuration method. The household garbage incineration fly ash demercuration method involves a desorption device, a heat exchanger, afreezing type mercury collector and a discharge hopper. A gas phase outlet of the desorption device is connected to a heat source inlet of the heat exchanger through an induced draft fan. A heat source outlet of the heat exchanger is connected to the freezing type mercury collector. A cold source inlet of the heat exchanger is connected with a cooling medium. A solid phase outlet of the desorption device is connected to the discharge hopper. The household garbage incineration fly ash demercuration method is simple in technology, convenient to operate, high in safety, good in demercuration effect and capable of reducing mercury pollution and achieves a mercury recycling effect.

Description

technical field [0001] The invention relates to the field of domestic waste incineration fly ash treatment, in particular to a method for removing mercury from domestic waste incineration fly ash. Background technique [0002] With the rapid development of China's economy, a large amount of energy and resources are consumed, which has caused some mercury pollution problems or potential mercury pollution problems. Mercury and its compounds are recognized as one of the substances that are harmful to the environment. Because of its high toxicity and long-distance migration characteristics, it is urgent for the international community to jointly control its impact and harm through regional and international cooperation. On May 18, 2017, the world took a historic step in the prevention and control of mercury pollution. The European Union and its seven member states ratified the Minamata Convention on Mercury. The Minamata Convention on Mercury, signed by my country, came into ef...
