Problems solved by technology

[0003] However, the heat source system for heating this high-temperature heat-conducting medium often uses coal as the fuel for combustion, which will generate additional pollution. As a liquid clean energy, ethanol is directly produced in the combustion process as water and carbon dioxide, and ethanol is renewable. energy, but few existing boilers exclusively use ethanol as fuel for industrial boilers

Abstract

The invention discloses a thermal desorption based soil repair heat source system. The system comprises an ethyl alcohol liquid supply device, an ethyl alcohol steam generator and a combustion heatingfurnace body; the ethyl alcohol outlet end of the ethyl alcohol liquid supply device is connected with the ethyl alcohol inlet end of the ethyl alcohol steam generator through an ethyl alcohol supplypipe; the ethyl alcohol steam outlet end of the ethyl alcohol steam generator is communicated with an ethyl alcohol steam guiding out pipe; by controlling the flow of liquid flowing from the ethyl alcohol supply pipe in real time and adjusting the heating power of an electric heating wire in real time, ethyl alcohol liquid is just gasified completely when flowing to the lower end of a spiral slope surface along an ethyl alcohol gasification spiral slope, and heat emitted by the slope surface of the whole ethyl alcohol gasification spiral slope is sufficiently utilized.

Description

technical field [0001] The invention belongs to the field of soil remediation, in particular to a heat source system and method for soil remediation based on thermal desorption. Background technique [0002] In the process of soil thermal desorption restoration, a spiral heating tube is set in a thermal desorption container filled with soft soil sources, and then a high-temperature heat transfer medium (heat transfer oil) is continuously introduced into the heating spiral tube, and then the thermal desorption container is heated. The soil is heated gently with non-direct fire, and the negative pressure environment is created to promote the rapid volatilization of chlorine-containing organic compounds such as PCBs. This non-oxidative combustion treatment method can significantly reduce the generation of dioxins. The exothermic spiral tube is used to treat the soil source The heating is stable and uniform, and the temperature control is convenient, avoiding the direct use of f...
