Vynález sa ďalej týka výrobku vyrobeného definovaným spôsobom a výrobkov na jeho vykonávanie.The present invention relates to a process for stabilizing and solidifying ash or smoke-depleting residues produced by the incineration of commercial waste. The invention further relates to an article made in a defined manner and to articles for carrying it out.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Je známe, že spaľovanie hospodárskeho odpadu je sprevádzané vyvíjaním dymu, ktorý obsahuje toxické prvky nebezpečné pre človeka a jeho životné prostredie.It is known that the incineration of economic waste is accompanied by the generation of smoke, which contains toxic elements dangerous to man and its environment.
Toxicita tohto dymu je v podstate následok toho, že dym obsahuje substanciu označovanú ako „popolček“, ktorý je tvorený pevnými zvyškami vznikajúcimi priamo spaľovaním odpadkov. Na zamedzenie znečistenia okolitého vzduchu takýmto toxickým dymom je známe čistenie odlučovačom prachu, ktorý zhromaždí takmer celé množstvo popolčeka obsiahnutého v dyme.The toxicity of this smoke is essentially due to the fact that the smoke contains a substance referred to as 'fly ash', which is formed by solid residues resulting directly from the combustion of garbage. In order to prevent contamination of the ambient air with such toxic smoke, it is known to purify with a dust separator which collects almost the entire amount of fly ash contained in the smoke.
Podľa možnosti sa zvyšky spaľovania hospodárskeho odpadu znova používajú alebo zhodnocujú rôznymi spôsobmi.Wherever possible, residues of the incineration of economic waste are reused or recovered in different ways.
Obzvlášť známe je vytváranie navážok použitím zmesi popolčeka a škvary.Particularly known is the formation of charges using a mixture of fly ash and slag.
Jednako však popolčeky, ktoré obsahujú silne znečisťujúce prvky, sa môžu odplaviť dažďom alebo vodou obsiahnutou v pôde, čo predstavuje nebezpečenstvo pre životné prostredie z dôvodov zvýšeného obsahu popolčekov v organických zlúčeninách, ako sú dioxíny a furány, alebo ťažkých kovov ako je olovo, ktorého množstvo je značne vyššie ako množstvo prípustné na ukladanie na skládkach.However, ashes containing heavily polluting elements may be washed away by rain or water contained in the soil, which presents a danger to the environment because of the increased ash content of organic compounds such as dioxins and furans or heavy metals such as lead. it is considerably higher than the amount permitted for landfill.
Skladovanie takýchto popolčekov nespracovaných a zmiešaných s inými odpadkami predstavuje nebezpečenstvo destabilizácie popolčekov s ohľadom na mnohé chemické reakcie, ktoré sa môžu v skládke vyvinúť a viesť k vyvíjaniu sírovodíka, k rozpúšťaniu organických zlúčenín a k obnoveniu rozpustnosti ťažkých kovov.Storing such ashes unprocessed and mixed with other refuse poses a risk of destabilization of the ashes in view of the many chemical reactions that may develop in the landfill and lead to the development of hydrogen sulphide, the dissolution of organic compounds and the recovery of the solubility of heavy metals.
Úlohou vynálezu je odstrániť tieto nežiaduce javy vytvorením jednoduchého a hospodárneho spôsobu neutralizácie popolčekov pri dobrých bezpečnostných podmienkach.The object of the invention is to eliminate these undesirable phenomena by providing a simple and economical way of neutralizing ash in good safety conditions.
