Description
Technical Field
The invention belongs to the technical field of hazardous waste treatment, and particularly relates to a pretreatment method and device for social source hazardous waste incineration residues.
Background
The centralized treatment of hazardous wastes mainly from industrial wastes in China starts late, but develops quickly, and the treatment of hazardous wastes by using incineration technology is developed in many places at present. According to the regulations of national records of hazardous wastes (2021 edition) and the like in China, the incineration residue of hazardous wastes still belongs to hazardous wastes.
At present, the method for disposing the hazardous waste incineration residue is mainly the cooperation of landfill and a cement kiln. The disadvantages of these two methods are: the landfill can not thoroughly solve the dangerous characteristic of hazardous waste incineration residues, and simultaneously occupies a large amount of land resources and cannot be continuous; cement kiln synergy is essentially a dilution process for hazardous substances (heavy metals) in the residue, and is limited by cement production and cannot be continued forever.
For example, chinese patent document CN106122980B discloses a process system for co-processing hazardous waste in a cement kiln, in which a hazardous waste incineration kiln 100 and a cement kiln 700 are operated independently, the hazardous waste is co-processed by the cement kiln 700 in an out-of-kiln process, and the waste is bypass-incinerated and homogenized and then is merged into the cement kiln 700. High-temperature flue gas generated after the hazardous waste is incinerated enters the decomposing furnace 701, harmful substances in the flue gas are adsorbed by utilizing the special alkaline environment in the decomposing furnace 701, and finally the purified flue gas is discharged along with the flue gas of the cement kiln 700 after reaching the standard. The incineration residue is discharged from the slag conveyor 104 after water quenching, is sent to a raw material system for batching, enters the cement kiln 700 along with the raw materials for incineration to form clinker, and the harmful components of the residue are solid-melted in the cement clinker.
And (3) carrying out high-temperature melting treatment on the hazardous waste incineration residue to form a vitrified product and simultaneously recovering valuable metals in the incineration residue. The formed vitrification product is an environment-friendly inert material, can be used as building and roadbed materials, and is a better method for treating hazardous waste incineration residues.
For example, chinese patent document CN112122307A discloses a dangerous waste plasma melting treatment system, which comprises a plasma melting furnace, a crusher, a granulator, an incineration slag bin, a fly ash particle bin, a mixing conveyor, a feeding buffer bin, a slag conveyor, a flue gas regulator, a rotary kiln incinerator secondary combustion chamber, and a plasma torch; the method adopts a plasma melting furnace to carry out incineration treatment on hazardous wastes, the main treatment materials are incineration residues, fly ash and other materials, and the treated furnace slag is non-toxic and harmless vitrified slag.
However, the application of the high-temperature melting treatment method to the dangerous waste incineration residue of social source has certain obstacles, mainly because the high-temperature melting of the dangerous waste incineration residue has higher requirements on the materials entering the furnace:
(1) the particle size distribution is uniform (preferably 3mm-5 mm), which is beneficial to compatibility homogenization and mass and heat transfer;
(2) compatibility of elements (CaO, SiO)2，Al2O3) The index requirement of forming the glass body is met, the ratio of the recoverable valuable metal and the reducing agent meets the proportion requirement, and the proportion of harmful elements is limited;
(3) the water content is less than 5%, the energy consumption is reduced, and the corrosion of acid is reduced;
(4) the material uniformity meets the melting precision requirement.
The social source hazardous waste incineration residue is characterized in that:
(1) the particle size distribution is not uniform;
(2) the shape difference is large, and the shape is block, particle and nodule (wrapped with unburnt substances);
(3) the water content is different, and the water content is dry or wet;
(4) the content of the components is different;
(5) non-homogeneous;
(6) the packaging is different, and mainly comprises three types of bulk materials loaded by a vehicle, ton bag packaging and square barrel packaging.
These factors have led to the inability of socially sourced hazardous waste incineration residues to be directly processed in a continuous feed at high temperature melt processing.
The prior art for treating the hazardous waste incineration residues through high-temperature melting lacks a systematic pretreatment process for the hazardous waste incineration residues, only has simple crushing pretreatment, and seriously restricts the application of treating the social source hazardous waste incineration residues through high-temperature melting.
