Description
Technical field
The utility model relates to a kind of combustible waste material system, specifically a kind of cement kiln associated treatment combustible waste material system.
Background technology
Combustible waste material refer to the mankind producing, in consumption, life and other activities solid-state, the semisolid waste material that have certain calorific value and can burn under certain condition that produce (external definition is more extensive, the discarded object that animal activity produces also belongs to this type of), be exactly generally " rubbish " of calorific value.Combustible waste material mainly comprises domestic waste, crop straw, mud, discarded plastics or rubber, damaged wood furniture, spoil, rotten food, human and animal excreta etc.
European Union is processing aspect the combustible waste materials such as domestic waste, mud, has several times and changes: just having started is that the lime-ash after burning is also landfilled taking landfill and burning as main; In succession there are several refuse landfill penetrating fluid leakage accidents in the later stage nineties, so they have revised and increased substantially the antiseep standards and guidelines of landfill yard; Experienced like this 6～8 years, European Union finds that remedial measure cost that they take is too high and it is little to produce effects, and can not effect a radical cure the hidden danger of secondary pollution; Through introspecting cautiously and painfully and proving, 2007 so far, and moral, Ying Deng state have made new decision-making finally in succession, no longer newly-built combustible waste and city life garbage landfill and incinerator factory; The combustible waste of all new generations from now on and rubbish all will be taked other safer more economical methods, all instant disposal as much as possible, settle at one go, dissolve clean, do not stay future trouble, as far as possible few with or without landfill yard and incinerator, explore the aspects such as anaerobic composting, regenerable solid fuel manufacture, exploitation bio-fuel, simultaneously also rather good to the dissolve prospect of combustible waste of cement industry.
The present situation of domestic combustible waste material is, because the combustible waste material generations such as domestic city house refuse are large, determined that China's offal treatment must emphasize " subtracting appearance ", through the groping and putting into practice of over half a century, the domestic main method to combustible waste material processing is burned exactly at present.This method one can be accomplished minimizing, and the combustible waste material one as mountain has been burnt to it; Two can realize resource, are used to generate electricity using combustible waste material as the energy.Therefore big and medium-sized cities, the whole nation from the leadership to the masses are all in a large amount of burning power stations of building the combustible waste materials such as rubbish, stalk, mud, and indivedual province has started that the rubbish for landfill is in the past dug out to one again and burnt it.
The processing mode that the advanced countries such as America and Europe have started to abandon burning rear landfill, but following the track of the overturned cart at home, what does is the drawback of waste incineration so? think after deliberation, it is the fatal disadvantage that combustible waste material burns that combustible waste material burning can not realize the innoxious of offal treatment.Why harmful waste incineration is, because domestic house refuse the like waste does not sort mechanism, domestic waste rubbish water content is many more than 35%, in the burning process of conventional oven grate furnace or fluid bed furnace etc. due to needs heat up, remove moisture, and can not burn rapidly, certainly existing the temperature space of 200-500 DEG C, in genus, low temperature burns, the in the situation that of a large amount of existence of chloride (as polybag), burning process just becomes the process of a large amount of manufacture bioxin.Current garbage burning factory is all first to manufacture bioxin, the pattern of then adsorbing by spraying into active carbon etc.This has just opened convenience Wei pollution and the murder by poisoning of bioxin to environment, wherein has the accident leakage of flue gas to cause bioxin to enter the reason of environment, more has the operating costs such as active carbon high and have Some Enterprises to steal due to row puts steathily.
Cement kiln associated treatment combustible waste material has suitable advantage, its natural stable hot environment can utterly destroy bioxin, natural alkaline environment can in and sour gas, curing heavy metal, component and the cement raw material of rubbish and lime-ash are similar simultaneously, also can be by rubbish " eat clean ", investment and processing cost is minimum, technological means is flexible.
Cement kiln associated treatment combustible waste material can bring a large amount of harmful components (as potassium, sodium, chlorine, sulphur etc.) that affect cement quality, and under the prerequisite that does not affect cement quality, the ability of cement kiln associated treatment combustible waste material is limited at present; Therefore, in order to improve the ability of cement kiln associated treatment combustible waste material, some technology have adopted the way of bypass, but bypass can bring extra energy loss, so the amount of leaking informaton generally can be controlled at kiln tail and export total exhaust gas volumn 5%-10%, also slightly inadequate.
