Description
Technical Field
The utility model relates to an adsorbent preparation field, concretely relates to magnesium aluminium hydrotalcite chloride ion adsorbent preparation facilities.
Background
With the increase of population and the continuous enlargement of economic scale, the energy consumption of China has been continuously increased for a long time. Because of abundant coal resources, reliable operation and mature technology of coal-fired power generation in China, the coal-fired power generation has been used as a main source of energy supply in China for a long time, but desulfurization wastewater generated in the power generation process becomes one of the most difficult wastewater to treat in coal-fired power stations.
The most widely and mature flue gas desulfurization process for coal-fired power stations at home and abroad is limestone-gypsum wet desulfurization technology, the desulfurization mode can maintain high desulfurization efficiency and gypsum quality, but chlorine elements from coal, limestone and process water are continuously enriched in desulfurization slurry, excessive chloride ions affect the desulfurization efficiency, the gypsum quality is reduced, and the corrosion of equipment is aggravated.
The desulfurization wastewater has high content of suspended matters, complex water quality, heavy metal and great treatment difficulty, and the traditional chemical precipitation method for treating the desulfurization wastewater effectively removes the suspended matters, the heavy metal and the like after the traditional triple-box treatment process of neutralization, coagulation and precipitation, but the removal effect of soluble salts such as chloride ions is poor, so that the desulfurization wastewater cannot be recycled or directly discharged. Therefore, the concentration of chloride ions in the desulfurization wastewater is a key control index, and if the content of chloride ions in the desulfurization wastewater can be reduced, the circulation rate of the desulfurization wastewater can be improved, so that the wastewater reduction is realized, and the method has an important significance for zero discharge of wastewater.
The adsorption method has the advantages of solid-liquid separation, simple operation, low cost, high efficiency and the like, and is widely researched in the chloride ion removal process. The aluminum magnesium hydrotalcite serving as an economic and environment-friendly adsorbent has the advantages of layered double hydroxides, large specific surface area, strong adsorption capacity and the like, and is widely researched and applied in the field of wastewater treatment. However, most of the currently applied researches focus on the treatment research of low-concentration wastewater with the chloride ion content of 100-1000 mg/L, and the research and the application of the high chloride ion content of the desulfurization wastewater of the coal-fired power plant are few.
In order to solve the above problems, in 2019, Ma Shu Liang He et al prepared magnesium-aluminum hydrotalcite with a molar ratio of magnesium to aluminum of 4: 1, and calcined the magnesium-aluminum hydrotalcite. The roasted magnesium-aluminum hydrotalcite is used as an adsorbent, has an obvious effect on the adsorption capacity of chloride ions in the desulfurization wastewater with the chloride ion concentration of 5000-20000 mg/L, and still has a promotion space. Therefore, the problem to be solved by the technical personnel in the field is to improve the adsorption capacity of the roasted magnesium-aluminum hydrotalcite on the chloride ions in the desulfurization wastewater with the chloride ion concentration of 5000mg/L to 20000 mg/L.
