Description
Technical field
The utility model relates to environmental protection equipment, is specifically related to a kind of flyash curing stabilizing device.
Background technology
Along with rapid development of economy, living standards of the people improve rapidly, and China's MSW generation sharply increases.The National urban house refuse amount of clearing only 5,398 ten thousand tons in 1987, surged by 1997 to 1.2 hundred million tons, within 2002, China's municipal refuse has reached more than 1.5 hundred million tons, and increases with the growth rate of annual 8% ~ 10%.The discharge of the municipal refuse sharply increased has become the key factor of restriction economic development, threat is also constituted to the living environment of the mankind, how to administer these rubbish cost-effectively, preventing pollution, also day by day become the hot issue in the urgent need to address that the whole society pays close attention to.In recent years, the output of house refuse and municipal solid wastes also day by day all increases, therefore house refuse and castoff burning and the flying dust that produces gets more and more, due to the not only low boiling heavy metal such as enriched lead, cadmium, mercury in flying dust, and be carcinogenic chief culprit, the main enrich body of dioxin-like chemical is a kind of dual danger wastes simultaneously with heavy metal, high leaching concentration and dioxin-like chemical high toxicity equivalent, if discharge flying dust arbitrarily, the pollution of air ambient can be caused.In order to reduce the secondary pollution that rubbish and castoff burning flying dust cause environment, therefore must by stabilizing fly ash, and solidfied material is transported to landfill yard and carries out landfill, prevent contaminated environment again.
Still feasible stabilization processes has following three kinds of methods at present:
A. cement-based solidified/stabilization technology: cement-based solidified is hydrate based on cement and water gelatification, heavy metal in flying dust is impregnated in the matrix of cement, under certain conditions through physics chemical action, refuse is cementing fixing in cement matrix, generates hard solidified cement body and loses transfer ability.Heavy metal finally rests on the form of hydroxide or complex compound the hydrated silicate colloid C-S-H surface that cement solidification formed, and the metal of also attaching most importance to that adds of cement provides alkaline environment simultaneously, inhibits the diafiltration of heavy metal in flying dust.Cement solidification flying dust technology is a kind of hazardous waste disposal technology of comparative maturity, in economy and operating aspect can have obvious advantage, but the consumption of cement is high, cause firming body increase-volume rate high, along with passage of time, firming body part noxious material may stripping gradually, there is long-term, potential threat to environment.
B. chemical agent stabilization technique: chemical agent stabilization technique utilizes chemical agent, after chemical reaction poisonous and harmful substance changes the process of low-solubility, low migration and hypotoxicity material into.Conventional stabilizing agent is inorganic matter and organic matter.Inorganic matter mainly contains Na2, S and phosphoric acid class medicament, organic medicament is chelate polymer material mainly, flying dust is mixed with the insoluble medicament with complex, in flying dust, ease of solubility metal (cd, pd etc.) is with after the complex reaction in medicament, form stability complex compound, and then be fixed in flying dust, reach with this and reduce the possibility that in flying dust, harmful components leach.The advantages such as with these chemicals treatment flying dusts above-mentioned, generally all can reach good effect, it is simple that the method has processing procedure, and equipment investment is few, but high concentration inorganic salt wastewater can be produced, need to process further.
C. melting and solidification technology: melting and solidification technology is mainly by flying dust and the mixing of the tiny nature of glass, after mixing granulation is shaping, melting under 1000-1400 DEG C of high temperature, usual about 30min (melting time is depending on the difference of flying dust character) is after the physics and chemistry state of flying dust changes, cooling makes it solidify, form glassy solids, by Vitrea compact crystal structure, guarantee the stable of heavy metal.The volume reduction rate of melting and solidification technology to residue is high, and solidification effect is good, but fatal defects is part, and noxious material evaporates, and must take vent gas treatment measure.So its system is more complicated, operating cost is high.
