Dexing party and government delegation visited Yiyang fly ash washing project

On the afternoon of February 20, 2022, Li Dan, the executive vice mayor of Dexing City, and Sun Ying, the vice mayor, led a Dexing party and government delegation to Yiyang for a field visit to fly ash washing. Chen changkai, deputy secretary of Yiyang County Party committee, and others accompanied the inspection. Luo Wu, assistant general manager of Ganzhou Haichuang, warmly received the delegation.

Luo Wu introduced the technical principle, process flow, environmental protection measures control and later development planning of Yiyang Haichuang water washing fly ash disposal technology to the delegation, and described in detail the advantages of collaborative disposal of fly ash by cement kiln compared with traditional landfill.

The landfill treatment of fly ash is to landfill the fly ash after chelating and curing with chemicals or cement. However, landfill occupies the country's valuable land resources and brings great environmental risks. Many areas are facing problems such as landfill site depletion, non-standard landfill, reagent failure and so on. For the collaborative disposal of fly ash in cement kiln, the fly ash is pretreated to extract resources such as potassium, sodium, sulfur and chlorine into industrial salt, and the remaining desalted fly ash is sent to cement kiln for high-temperature calcination. Under the high temperature condition of cement kiln, dioxins are completely decomposed and heavy metals are completely solidified, which can meet the environmental protection policy of fly ash reduction, recycling and harmlessness, and realize continuous industrial production.

After the visit, Li Dan praised the advanced technology and high sense of social responsibility of conch entrepreneurship, and said that ecological and environmental protection is related to people's well-being and long-term development. The credit lies in the present and the future. The collaborative disposal of waste incineration fly ash by cement kilns has truly realized the "turning waste into treasure" and driven the development of regional environmental protection industry and circular economy. He hopes to further strengthen government enterprise communication and deepen cooperation in the future, Jointly promote the development of environmental protection in surrounding areas.
