Embodiment Construction

[0047] The above-mentioned purpose of the present invention and its structural and functional characteristics will be described according to the preferred embodiments of the accompanying drawings.

[0048] The present invention provides a method for separating mercury, cracking dioxin and organic substances by using high temperature steam and circulating heat source, please refer to figure 1 , is a preferred embodiment of the present invention, as shown in the figure, its processing flow is described as follows:

[0049] Soil pretreatment 251 Because the organic matter contained in the soil is low, energy consumption is required in the treatment. In order to reduce the use of energy and make the modified soil contain a large amount of activated carbon, it is necessary to add carbon-containing substances when treating the soil. This carbonaceous substance can be the following substances: substances containing organic matter; substances containing dioxin; substances containing m...

Abstract

The invention relates to a method for separating mercury, cracking dioxin and organic substances by using high-temperature steam and circulating heat sources. Firstly, carbon-containing substances are added according to the proportion of organic substances in the soil, and then the above-mentioned soil is sent into the reaction chamber in an air-isolated manner. ; Send the high-temperature hot gas from the first combustion chamber into the second combustion chamber to heat the reaction chamber and the high-temperature steam generator; send the high-temperature steam from the high-temperature steam generator into the reaction chamber, and maintain thermal balance with waste and soil, so that the soil The mercury, organic matter and dioxin in the gas are distilled and taken out with the steam, and then the vapor containing mercury, organic matter and dioxin is separated, and the separated fuel gas and fuel oil are sent to the burner to generate the above-mentioned high temperature The hot air, the treated soil, is discharged in a way that is isolated from the outside air, and the temperature is rapidly cooled.

Description

technical field [0001] The invention relates to a method for separating mercury, cracking dioxin and organic substances by using high-temperature steam and a circulating heat source, in particular to a method for treating soil improvement and waste treatment, especially referring to the circulating heat source generated during the utilization process , and high-temperature steam to separate mercury, pyrolyze dioxin and organic substances. Background technique [0002] Soil is polluted by mercury, dioxins, and organic solvents. Due to the low content, it is very difficult to treat. Therefore, there is no successful and mature technology for soil treatment that can simultaneously separate mercury and decompose dioxins. [0003] China Taiwan Patent, Announcement No. 478979, the patent name is the invention patent of the non-polluting treatment method and device for organic waste recycling, which is mainly equipped with coke for secondary cracking in the latter part of the waste...
