Description
Technical field
The utility model relates to technical field of soil remediation, and in particular to a kind of thermal desorption device for handling contaminated soil.
Background technique
Largely left place soil is especially high there are serious pollution problem after the resettlement of chemical industry, oil play
Concentration organic contamination place has the characteristics that pollution condition is complicated, area is big, repairing and treating is difficult.The World Bank is sent out for 2010
" As-Is analysis of the reparation and redevelopment of Chinese contaminated site " report of cloth shows have in the place that industrial enterprise's resettlement is left
Nearly 1/5 there are more serious pollutions.2005-2013 years national soil pollution situation tune of Chinese Ministry of Environmental Protection and Ministry of Land and Resources's publication
Bulletin is looked into, as the result is shown in Industrial-Enterprises in China land used, has the soil higher than 30% to be contaminated.Process is utilized in redevelopment
In, the organic pollutant in soil can directly affect the health of the mankind.Therefore, it is necessary to properly be located to contaminated soil
It sets, ensures the safety of the mankind and environment.
Soil thermal desorption technology is a kind of effective means of renovation of organic pollution soil, mainly by directly or indirectly adding
Organic pollutant in soil is heated to sufficiently high temperature by heat, separates it from soil.Soil thermal desorption needs to consume
A large amount of heat, the exhaust gas after desorption, which is also required to special cleaning equipment, which carries out harmless treatment, to discharge.So Soil Thermal
Desorption method often has that equipment is more, energy consumption is high, takes up a large area, the problems such as operating cost is high.
Utility model content
The utility model is to provide a kind of thermal desorption device for handling contaminated soil for the above technical problems.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of thermal desorption device handling contaminated soil, the device include speed regulation batcher, and the speed regulation batcher is logical
It crosses elevator to be connected with the first flap valve, first flap valve is connected by moisture drying kiln with the second flap valve, described
The second flap valve by calcining kiln with discharge tower be connected.
In some specific technical solutions: the output end of the first biomass burner is connected with calcining kiln, and described forges
The output end of firing is connected by deduster with high-temperature blower, and the high-temperature blower passes through the second biomass burner and second
Flap valve is connected.
In some specific technical solutions: the output end of first flap valve is connected with air-introduced machine.
The biomass burner of the utility model provides heat for contaminated soil thermal desorption, and contaminated soil passes through moisture drying
Kiln, calcining kiln and heating flue gas carry out heat exchange, using different temperatures gradient-heated.Flue gas a part of heat exchange is completed through arranging
Port discharge handles rear discharge up to standard, and a part of reuse utilizes, and carries out contaminated soil thermal desorption again by biomass burner
Process.
The utility model has the beneficial effects that
Device disclosed by the utility model has the characteristics that heat utilization rate height, thermal energy step utilize, and can greatly reduce throwing
Provide cost.

The output end of first flap valve (3) is connected with air-introduced machine (4).
Embodiment 1
Contaminated soil to be processed enters dry kiln by elevator and carries out counter-current drying, to increase the utilization rate of heat,
100-200 degrees Celsius for the treatment of temperature, treated soil enters calcining kiln by flap valve, is provided by the first biomass burner
Thermal energy carry out thermal desorption processing, 400-700 degrees Celsius for the treatment of temperature.The flue gas generated in treatment process, a part is by removing
Dirt device enters the second biomass burner and carries out burning disposal, and the heat circulation of generation enters dry kiln.A part passes through tail gas
Handle rear discharge up to standard.
Pollutant concentration is as follows before and after the processing using the processing method for certain pilot plant test:
| Number | Pollutant | Highest concentrations | Concentration after processing | Whether reparation target is reached |
| 1 | Benzo (b) pyrene | 434 | 1.87 | It is |
| 2 | Benzo (b) fluoranthene | 668 | 1.98 | It is |
| 3 | Dibenzo (a, h) anthracene | 29 | 0.14 | It is |
