A kind of hot fume injection contaminated soil original position thermal desorption heating means of surface burning, are fired according to above-mentioned surface
What the hot fume injection contaminated soil original position thermal desorption heating device of burning was realized, by the fuel gas inlet on gas distribution pipe road to each
A metal fiber burner feeds the clean natural gas of certain pressure, passes through the combustion air of gas distribution pipe road inside sleeve
Entrance feeds the combustion air of certain pressure to each burner, makes to heat in outer tube by the infeed of natural gas and combustion air
Portion burns after keeping certain positive pressure, combustion air and combustion gas to mix in burner in metallic fiber outer surface, the heat of generation
A part is transferred to heating outer tube, and then indirect heating periphery heated medium by way of radiating and conducting, due to heating
The positive pressure of outer tube, the flue gas for generation of burning, will be entrained by slit or aperture injection heated medium on outer tube wall
Heat be directly conducted to heated medium.
Compared with prior art, the present invention has following remarkable result:
(1) due on this heating device micro metal fiber surface burner use distributed arrangement, make metal outer pipe by
Hot uniformly external quantity of heat given up is evenly distributed, and passes to that metal outer pipe heat is more, and the flue gas for generation of burning passes through on outer tube wall
Slit or aperture inject heated medium, the thermal efficiency is higher.
(2) this heating device metal outer pipe part is low by calcination intensity, and the present apparatus is made to have longer service life.
(3) this heating device uses the micro metal fiber surface burner of distributed arrangement, keeps fuel abundant, saves energy
Source.
Detailed description of the invention
