Design and preparation method of nano mercury-removal material taking mussel shell as raw material

Abstract

The invention discloses design and preparation method of a nano mercury-removal material taking a mussel shell as a raw material. The method comprises the following steps that typical mussel shells are collected; characterization analysis is carried out on mussel shell samples to establish a mussel shell database; modified treatment is carried out on the mussel shell samples; according to the mixing ratio of various mussel shell materials, a variety of nano mercury-removal material formulas are designed; the various mussel shell materials are mixed according to proportions according to the formulas to prepare the nano mercury-removal material; the mercury adsorption capacity of the nano mercury-removal material is tested, and the nano mercury-removal material is evaluated and screened; andthe nano-mercury material is characterized in situ. The design and preparation method of the nano mercury-removal material taking the mussel shell as the raw material have the advantages that the fire coal Hg control technology and environmental treatment material research are combined to provide a fire coal flue gas mercury-removal material taking the mussel shell as the raw material, thereby contributing to promoting comprehensive utilization of coastal solid wasted mussel shell resources, realizing waste treatment with processes of wastes against one another and developing a circular economy.

Description

Technical field [0001] The invention relates to the technical field of coal-fired flue gas mercury removal materials, in particular to a design and preparation method of a nano mercury removal material using mussel shells as raw materials. Background technique [0002] Coal-fired power plants, coal-fired boilers, petroleum refining and chemical industries, non-ferrous metal smelting industries, waste incineration power generation, and heavy metal polluted land treatment and remediation project flue gas exhaust gas neutralization of coke oven gas, water gas, natural gas, shale gas and other fossil energy related The fuel gas contains heavy metal mercury. Mercury has become the most concerned atmospheric carcinogenic pollutant after sulfur dioxide and nitrogen oxide because of its high toxicity, volatility, persistence and deposition in organisms. Mercury causes great harm to organisms and the environment. The mercury released from the above industries can spread hundreds of kilom...

Problems solved by technology

On the other hand, with the rapid development of mussel farming and processing along the coast, a large number of shells are produced, and the discarded mussel shells have caused serious pollution to the coastal ecological environment, which has become an environmental hazard that needs to be solved urgently in coastal areas.
