Description
Technical field
The present invention relates to soil remediation processing technology field more particularly to a kind of soil thermal desorption prosthetic devices.
Background technology
There is the pollution that a large amount of soil are subject to the organic pollutions such as benzene,toluene,xylene, ethylbenzene and TPH in China, with public affairs
Crowd is to the gradually understanding of organic contamination substance environment and health hazard, and urgent need is economical and effective ways handle these toxic substances
Matter.The recovery technique of main organic pollution contaminated soil has biological prosthetic, chemical remediation, peripheral doses etc., comparatively,
Peripheral doses or chemical remediation have wider applicability, especially suitable for high concentration, multicomponent organic contamination place.In crowd
In more peripheral doses or chemical remediation technology, thermal desorption is the mature and reliable technology for generally acknowledging processing organic material contaminated soil.
Thermal desorption recovery technique is by directly heating or indirectly heat, contaminated soil being heated to enough temperature, is made
Organic pollution contained by it is able to the process volatilized or detached.Thermal desorption is the object from an inversion of phases for another phase by pollutant
Separation process is managed, selectively target contaminant can be made to wave by the temperature and residence time of material that control thermal desorption system
Hair.Direct pyrolysis device (CN101712042A) carries out thermal desorption using the mode that directly heats, but heat source gas and volatilization
The polluted gas gone out is mutually mixed, and increases the processing cost of follow-up tail gas, and system energy consumption is high and heat utilization efficiency is low.Therefore
How thermal desorption equipment operation energy consumption is reduced, energy-saving and emission-reduction are current thermal desorption recovery technique urgent problems to be solved.
