Description
Technical Field
The invention belongs to the field of tail gas treatment, and particularly relates to a process for treating tail gas of a solid waste incinerator.
Background
In recent years, with the development of the economic level of China and the improvement of the living standard of people, various solid waste garbage is increasing day by day. At present, the treatment of solid waste is mainly sanitary landfill and incineration. In recent years, the solid waste treatment market is developed rapidly, the market prospect is wide, and incineration power generation gradually replaces landfill and becomes a main mode of solid waste treatment. The solid waste mainly comprises domestic waste and production waste, the solid waste has complex general components, high water content and low heat value, and the solid waste is burnt insufficiently and is easy to generate secondary pollution. The tail gas after solid waste incineration mostly contains acidic gases (such as NO)X、HCl、SOXHF, etc.), dioxin (PCDDS/PCDFS), and heavy metals (Hg, Pb), which would cause serious environmental pollution if discharged directly without treatment.
The paper "research on waste incineration flue gas purification process" (LinYuze; Yangchang; Sungqi; Zhang break Yu; Huangyueqin; research on waste incineration flue gas purification process [ J ]; scientific technological innovation; 32 years 2018; page 151-) -152) indicates that:
the Shanghai Jiangqiao domestic waste incineration plant adopts the processes of 'SNCR (urea) + dry method + bag-type dust remover + wet washing tower', and simultaneously sprays slaked lime and activated carbon in front of the bag-type dust remover to treat flue gas, and the energy expansion project is characterized in that a wet deacidification system is added behind the dust remover, and the dry method + wet method process can ensure that the removal rates of HCl and SO2 are respectively 99% and 97%.
A large-roof mountain garbage incineration plant in a large continuous development area adopts the processes of SNCR (urea), a semi-dry method, a dry method (sodium bicarbonate), activated carbon injection and a bag-type dust remover, an absorbent is lime slurry, the sodium bicarbonate is reserved, and the index of flue gas after treatment is far ahead of the national standard.
A waste incineration power plant in Haian county of Nantong city of Jiangsu province adopts the processes of SNCR (urea), a semi-dry method, a dry method (sodium bicarbonate), activated carbon injection, a bag type dust collector and SCR, and adopts a low-temperature SCR technology and TiO2 as a catalyst carrier, so that various pollutants can meet the requirements of European Union environmental standard system 2000.
At present, the waste incineration plants in China mainly adopt the processes of SNCR, semi-dry deacidification, activated carbon injection and bag-type dust remover to treat smoke, and can meet the current national emission standard of pollutants in smoke. However, the content of dust in the flue gas at the outlet of the incinerator is generally 20g/Nm3, the dust is mostly non-combustible inorganic matter, combustible components are changed into gas through combustion, and the gas contains a lot of acidic substances, and toxic gases such as dioxin (PCDDS/PCDFS) and heavy metals (Hg and Pb) and the like. Although the toxic gas can be removed by the process, the toxic and harmful gas pollutants are completely collected into the dedusting ash by the bag-type dust collector, so that a large amount of dedusting ash cannot be comprehensively utilized, the yield of the dedusting ash is high, and the treatment cost is increased due to large amount of the dedusting ash during treatment.
