Problems solved by technology

Therefore, due to the high price of the device, it is expected to find high-temperature resistant inorganic filters and adsorbent materials that do not require post-treatment
[0009] In the past, the known methods of treating residual ash and fly ash containing heavy metals include the treatment method of mixing chelating agents produced by organic matter such as carbamic acid. This method is widely used, but it is difficult to evaluate the stability of the chelating method chemically. properties, so it is necessary to find a way to chemically stabilize heavy metals in ion-binding

Embodiment 1

[0050] The silanolate liquid (LC) of the present invention does not decompose even if it is heated, and it is gradually dehydrated to 1000°C, and the process of being converted into siloxane is carried out with 20°C, 250°C, 550°C, 950°C in Fig. 1-4 FT-IR chart (analysis result of Toray Research Center) shows. It shows that the peak value of water molecules decreases as the temperature rises to form a film.

Embodiment 2

[0052] Table 1 shows the component analysis values ​​of LC used in Example 1. Although LC contains the elements used as raw materials, the compositional ratio of elements to be analyzed is not limited thereto.

[0055] *Analysis result of Agne Technology Center

[0056] Such compositional ratios are similar to the analysis values ​​of the enamel base glaze, so heat hardening and ceramic coating can also be achieved.

Embodiment 3

[0058] The silanolate solution (LC-150) of the present invention has a solid content of 50%, a specific gravity of 1.5, and a pH of 12.2. The water loss of its adsorbed moisture in different temperature ranges is shown in Table 2. In addition, the 20-1200 The specific heat between °C, thermal diffusivity and thermal conductivity are shown in Table 3 (Agne Technology Center analysis value). Dehydration continues to high temperature, from normal temperature to 1000 °C, the specific heat, thermal diffusivity, and thermal conductivity do not change very much, which shows that LC-150 is difficult to rise in temperature even at high temperature, and can be used as an endothermic agent for exhaust gas temperature kick in. If excess water exists, due to the synergistic effect, it has an endothermic quenching effect.

Abstract

The present invention discloses a castoff cleaning treatment method which is characterized in that: the water film-forming inorganic compound consisted of siloxane and silanol salt contacts with the inflamed gases and flying ash of the castoff to form film-forming dilatant becoming the combustion residue containing black smoke, effluvium, harmful gas and heavy metal, and at the same time, the castoff consisted of black smoke, effluvium, harmful gas and heavy metal which are seemed as the injurant and the public injurant are sealed and burnt for the seal cleaning treatment of the the injurant and the public injurant containing black smoke, effluvium, harmful gas and heavy metal.

Description

[0001] This application is a divisional application of the invention patent application with the application number 99100417.5, the application date is January 9, 1999, and the invention title is "Purification and treatment of harmful gases and incinerator bottom ash and other purification treatment methods". technical field [0002] The present invention relates to a purification treatment product and a purification treatment method of harmful gas containing black smoke, stench, heavy metal and fly ash, and residual ash accumulated at the bottom of an incineration device. Background technique [0003] From the point of view of the living environment, not to mention the black smoke and stench produced when the waste is burned, even the dissolution of harmful heavy metals contained in the discarded incineration ash and the discharged fly ash, and the dioxins that have been strictly restricted in Europe emissions are strictly limited. [0004] However, administrative guidance ...
