Abstract
The invention provides a suspension thermal desorption furnace for restoring organic contaminated soil. The suspension thermal desorption furnace comprises a suspension thermal desorption furnace body and a pre-combustion chamber. The suspension thermal desorption furnace body communicates with the pre-combustion chamber through an inclined pipeline; a secondary blowing air inlet is formed in the lower portion of the suspension thermal desorption furnace body; a fuel inlet is formed over the pre-combustion chamber; and a contaminated soil inlet and a primary blowing air inlet are formed in the side surface of the upper portion of the pre-combustion chamber. The suspension thermal desorption furnace for restoring the organic contaminated soil has the beneficial effects that the thermal desorption process of the organic contaminated soil is performed in the suspension state by the aid of the aerodynamic principle after the organic contaminated soil enters the suspension thermal desorption furnace body, and the combustion process of fuel, the thermal desorption process of contaminants and the combustion process of the contaminants are performed in the suspension space state at the same time, so that the defects of thermal desorption in the stacking state in the prior art are overcome, accordingly, the heat transmission efficiency is greatly improved, the combustion heat enthalpy of some contaminants is directly transmitted to contaminants which are not yet thermally decomposed, the desorption efficiency is high, and fuel consumption is low.
