Description
Technical Field
The utility model relates to an environmental protection technology field, concretely relates to resourceful treatment device of mother liquor of msw incineration flying dust and hydrochloric acid reaction.
Background
With the rapid development of urban economy in China, the urban garbage yield increases day by 8-10% every year. The basic treatment modes of domestic and foreign municipal domestic garbage are landfill, incineration and composting, and the incineration method gradually becomes the trend of municipal waste treatment due to the advantages of small occupied area, short treatment time, obvious reduction (the mass reduction generally can reach 70 percent, and the volume reduction can reach 90 percent), more thorough harmless treatment, capability of recovering waste heat from garbage incineration and the like.
The waste incineration fly ash refers to incineration residue collected by a flue gas purification system of a waste incineration plant, the generation amount of fly ash per ton of waste incineration in China is 30-200 kg, the number of the grate furnaces is 30-50kg, and the number of the fluidized beds is 150 kg. The fly ash contains heavy metals with high leaching toxicity, soluble salts and organic chlorides (polychlorinated biphenyl and dioxin), is generally considered as a dangerous waste and has great threat to the environment. The surface and the interior of the incineration fly ash are both enriched with a large amount of heavy metals, wherein the Zn and the Pb are the most, the leaching concentration is as high as 35.84mg/L and 5.98mg/L, and the underground water quality can be seriously polluted by direct landfill.
At present, fly ash is treated by mainly adopting cement solidification and chelating agent stabilization methods in China, and the solidified fly ash is mainly transported to a household garbage landfill site for landfill. A small amount of cement is prepared after pretreatment and washing through a cement kiln, the fly ash contains a large amount of calcium hydroxide and chloride, the content of the chloride is too high, the viscosity of calcium hydroxide slurry is high, the mixing cannot be uniform in the washing process, and the calcium hydroxide slurry is easy to block during filtering or conveying, so that the washing dechlorination effect is low, and the subsequent cement kiln cooperative treatment or other harmless treatment is influenced. Thus, patent application No.: 202010049471.7 provides a method for making calcium hydroxide and calcium carbonate react with fly ash by hydrochloric acid to convert calcium chloride into calcium hydroxide, then washing with water to remove chlorine salt in fly ash, and making the filtered ash go to cement kiln for cooperative treatment or high-temperature melting treatment to make harmless treatment. Filtration mother liquor for fly ash reaction with hydrochloric acid, patent application No.: 202010049471.7 is the following method: cooling and crystallizing mother liquor, filtering crystallized salt to obtain a chlorine salt mixture mainly containing potassium chloride, wherein the filtrate has two ways, namely I is continuously frozen and crystallized to obtain 6-water calcium chloride, then drying to obtain a flaky anhydrous calcium chloride or powdery anhydrous calcium chloride byproduct, and returning the crystallized mother liquor; and II, cooling the mother liquor to obtain granular calcium chloride through a boiling granulation tower.
The mother liquor treatment scheme adopts a scheme of cooling crystallization and drying: the reaction mother liquor is cooled and crystallized to obtain mixed salt mainly containing sodium chloride for treatment, then is frozen and crystallized to obtain 6-water calcium chloride, and the 6-water calcium chloride is dried to obtain anhydrous calcium chloride for sale, so that the recycling treatment of the mother liquor is realized. However, the scheme has the defects of unstable crystal, easy dissolution, difficult solid-liquid separation and the like of 6-water calcium chloride, so that the production process is difficult to control and continuous and stable production is difficult to realize in the case of anhydrous calcium chloride.
Further patent application No.: 202010049471.7, the energy consumption is high because the calcium chloride hexahydrate is dried to prepare the dihydrate or anhydrous calcium chloride after the 6-water calcium chloride crystal solution is obtained by cooling and crystallizing.
Accordingly, there is a need for improvements in the art.
