Problems solved by technology

The invention can solve the problem of occupying a large amount of land when vitrified products of hazardous waste are landfilled, and reduce the use of packaging materials such as plastic cylinders and iron drums used in landfilling other hazardous wastes. At the same time, glass containers made of hazardous wastes are broken or If it cannot be reused, it can be crushed and then re-entered into the melting furnace to remake glass products

Embodiment 1

[0037] In this embodiment, the raw materials are incineration industry waste residue, metallurgical industry waste residue, admixture oxide BaO and caustic soda, and the waste residue contains silicon, alkali metal and some combustible components. Combustible components in the raw material are incinerated at high temperatures, and the remaining material is melted and vitrified. In the present embodiment, the specific preparation method is as follows:

[0038] (1) The above-mentioned hazardous wastes containing silicon and alkali metal oxides or combustible components are mixed so that the oxide ratio (mass percentage) is: 65% SiO 2 ,2%Al 2 o 3 ,6%CaO,1%MgO,Na 2 O+K 2 Total O is 13.5%, FeO+Fe 2 o 3 The total is 2%, 0.5% BaO, and the balance is impurities. The above-mentioned mixture is used as a raw material after ball milling to reach a particle size of 0.2mm, pre-dried to a moisture content <10%, and then put into a high-temperature melting furnace for hazardous waste ...

Embodiment 2

[0046] In this example, the container prepared in Example 1 is used for reliable and low-cost disposal of hazardous waste. The specific treatment methods are as follows:

[0047] 1) From the hazardous wastes to be disposed of, the hazardous wastes containing silicon and alkali metal oxides are selected as raw materials, and made into multiple hazardous waste landfill containers according to the process of Example 1. Simultaneously, in step (4), reserve the molten glass liquid that discharges in part furnace body.

[0048] 2) Put the remaining hazardous wastes into the hollow barrel body 1 of the above-mentioned container, fill it up and cover the glass cover 2, and then pour the reserved molten glass into the gap between the glass cover 2 and the hollow barrel body 1 , to strengthen the seal to prevent the internal hazardous waste from leaking and entering the landfill to cause harm to the surrounding environment.

[0049] 3) Put the sealed container together with the hazard...

Abstract

The invention discloses a hazardous waste landfill container and a preparation and disposal method thereof. The dangerous waste landfill container of the present invention is composed of a glass barrel and a glass cover, and the raw material of the glass container comes from wastes containing silicon and alkali metals or combustible wastes in the "National List of Hazardous Wastes (2016 Edition)". In the manufacture of glass containers, glass-ceramics whose hardness is stronger than tempered glass is obtained through secondary sintering, and after being shaped into a barrel, potassium phosphate spray annealing is carried out to strengthen it. During waste disposal, the hazardous waste is put into the barrel and then liquid-sealed with high-temperature molten glass to form a complete closed barrel, which is then filled as a whole. The container of the present invention has good strength performance and sealing performance, and it is used in the disposal process of hazardous waste without the assistance of other packaging materials at all, and will not generate new pollution, and it only needs to glass part of hazardous waste. The energy consumption is also greatly reduced.

Description

technical field [0001] The invention relates to the field of hazardous waste treatment, in particular to a hazardous waste landfill container and a preparation and disposal method thereof. Background technique [0002] The "National Hazardous Waste List (2016 Edition)" contains alkali metal-containing, silicon-containing waste or combustible waste, and these waste residues contain a large amount of heavy metals and organic matter. At present, the general research and treatment direction at home and abroad is to vitrify hazardous waste through oxide ratio and compatibility, and to fix heavy metals and incinerate organic matter through high-temperature melting. However, such waste is usually huge in volume. If all the waste is vitrified, the energy consumption is extremely high, and the corresponding cost is also relatively high, which is not conducive to promotion. Moreover, vitrification products that have undergone vitrification of hazardous waste in China and meet domesti...
