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

The invention discloses a thermal desorption heat source system for soil restoration, which includes an ethanol steam generator, and the inside of the ethanol steam generator includes an ethanol liquid pressure storage chamber and an ethanol steam generation chamber distributed up and down, and the ethanol liquid pressure storage chamber An isolation plate is set between the cavity and the ethanol vapor generating cavity, and a heat insulation cavity is arranged inside the isolation plate; a liquid injection pipe is also coaxially arranged on the isolation plate, and the upper end of the liquid injection pipe communicates with the An ethanol liquid pressure storage chamber, the lower end of the liquid injection pipe is provided with a liquid outlet head, and the liquid outlet head is located on the top of the ethanol vapor generation chamber; and a first liquid solenoid valve is arranged in the liquid injection pipe; by real-time adjustment of the electric heating The heating power of the heating wire makes the ethanol liquid flow down the metal vaporization slope to the lower end of the spiral slope just completely gasified, so that the heat emitted by the entire metal vaporization slope can be fully utilized and maximized. Improve steam generation efficiency.
Description
technical field [0001] The invention belongs to the field of soil remediation, and in particular relates to a heat desorption heat source system and a method thereof for soil remediation. 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 direc...
