105, desorption chamber 102 is equipped with chimney 104, and chimney 104 is located at close to one end of discharge port 105, and the both sides of desorption chamber 102 are equipped with
Burner 103, during work, contaminated soil is moved in extraction tube 101 from the front end of feed inlet 106 to the rear end of discharge port 105
It is dynamic, and the heat smoke that burner 103 generates flows, then discharged from chimney 104 in desorption chamber 102 to chimney 104, due to chimney
104 are located at close to one end of discharge port 105, and therefore, the flow direction of heat smoke is identical with the moving direction of contaminated soil, hot cigarette
The generally straight movement of mobile route of gas, not only there is heat smoke, the residence time is short in desorption chamber 102, and heat exchange efficiency is low
The problem of, and the temperature that will also result in 101 lower section of extraction tube is higher, the temperature of 101 top of extraction tube is relatively low, extraction tube 101
Upper and lower temperature difference it is larger, be susceptible to the situation that extraction tube 101 upwarps deformation.
Utility model content：
The technical problems to be solved in the utility model is to provide a kind of heat exchange efficiency height, can effectively prevent extraction tube and upwarps
The multistage counter current heating thermal desorption device of deformation.
The technical solution of the utility model is to provide a kind of multistage counter current heating thermal desorption device, including desorption chamber,
Multiple burners and positioned at indoor extraction tube is desorbed, the front end of extraction tube is equipped with feed inlet, and the rear end of extraction tube is equipped with out
Material mouth, extraction tube is interior to be equipped with auger, and desorption chamber is equipped with chimney, and extraction tube is equipped with vapor outlet port, wherein, chimney, which is located at, to be desorbed
It is arranged in the groove set on desorption chamber bottom close to one end of feed inlet, multiple burners on room, each burner spray
The flame direction gone out is consistent with the direction of advance of the contaminated soil in extraction tube.
A kind of multistage counter current heating thermal desorption device described in the utility model, wherein, it is set between desorption chamber and extraction tube
There is the spiral septum around extraction tube, spiral septum is separated into the inner cavity of desorption chamber the spiral cigarette around extraction tube
Conductance chute.
A kind of multistage counter current heating thermal desorption device described in the utility model, wherein, multiple burner gaps are arranged in
In the groove being correspondingly arranged on desorption chamber bottom, vapor outlet port is divided into steam outlet and pollutant vapor outlet port, and vapor goes out
Mouth is located on the leading portion of extraction tube, and pollutant vapor outlet port is located on the back segment of extraction tube.
A kind of multistage counter current heating thermal desorption device described in the utility model, wherein, desorption chamber both sides, which are hinged with, to be used for
The weather shield protected to burner.
After more than structure, compared with prior art, a kind of multistage counter current heating thermal desorption device tool of the utility model
It has the advantage that：Since chimney is located in desorption chamber desorption chamber bottom is arranged at close to one end of feed inlet, multiple burners
In the groove of upper setting, the flame direction that each burner sprays is consistent with the direction of advance of the contaminated soil in extraction tube.
Therefore, the heat smoke that burner generates is run to the back-end from first in extraction tube lower part, and then portion moves bottom-up, finally
Flue gas is moved to the chimney direction close to feed inlet one end, that is to say, that the heat smoke that burner generates is extracting indoor path
To be U-shaped, the moving direction of heat smoke is first consistent with the direction of advance of contaminated soil, then again with the direction of advance phase of contaminated soil
Instead, heat smoke residence time in desorption chamber is not only increased, heat smoke can be made to go heating contaminated soil to greatest extent,
The heat exchange efficiency of heat smoke is improved, reduces energy consumption, and the U-shaped path of heat smoke can be to carrying out more above extraction tube
Good heating, makes extraction tube upper and lower temperature difference smaller, extraction tube is not in the situation for upwarping deformation.In addition, it fires in the prior art
Burner is arranged on the both sides of desorption chamber, and burner is exposed at the outside of desorption chamber, whole Transporting inconvenient in this way, and when transport usually will
Burner is removed, after reaching scene, then burner is loaded onto, and the burner of the utility model is arranged on desorption chamber bottom
In the groove of setting, since burner is not exposed at the outside of desorption chamber, when transport, does not have to remove burner, facilitates whole fortune
It is defeated, integrated level also higher.
The spiral septum around extraction tube is equipped between desorption chamber and extraction tube, spiral septum is the inner cavity of desorption chamber
Being separated into the effect of the spiral flue gas diversion trench around extraction tube is：The heat smoke that burner generates can only be along around carrying
The spiral flue gas diversion trench of pipe is taken to move, that is to say, that the heat smoke that burner generates is transported around extraction tube spiral shape
It is dynamic, it can make that the heating of extraction tube is more uniform, and extraction tube upper and lower temperature difference further reduces in this way, further increase heat smoke and exist
Residence time in desorption chamber improves the heat exchange efficiency of heat smoke.
Multiple burner gaps are arranged in the groove being correspondingly arranged on desorption chamber bottom, and vapor outlet port is divided into vapor and goes out
Mouth and pollutant vapor outlet port, steam outlet is located on the leading portion of extraction tube, after pollutant vapor outlet port is located at extraction tube
Effect in section is：It can be by adjusting the output of each burner so that the heating temperature that each section of extraction tube is different, can basis
Moisture or content of organics and boiling point in contaminated soil are provided separately, and if leading portion is mainly dry soil, evaporate moisture, can
Lower temperature to be set, rear end is mainly evaporated organic, temperature can be set it is higher, specifically can be according to organic
The boiling point of object is set, and the vapor of leading portion can be made to be discharged by steam outlet, and organic pollution steam can be from pollution
Object vapor outlet port is discharged, and can carry out respective handling respectively.
The effect that desorption chamber both sides are hinged with the weather shield for being protected to burner is：Burner can be played
The effect to protect from the wind and rain, since weather shield and desorption chamber are hinged, weather shield can be opened can also put down at the scene, both
Burner can be protected, and facilitates the maintaining of burner.
