Foundation soil and underground water are entered, enterprise former address place is caused to become industrial pollution place.As in economically developed Pearl River Delta
Area, once the plant area of the enterprises such as densely covered hardware, chemical industry, steel, soil received serious heavy metal pollution, seriously affected
Local ecological environment, constrains expanding economy at the health for threatening people.Therefore, place heavy-metal contaminated soil
Reparation, it has also become influence people's lives, urban planning and sustainable development obtain a significant problem.
Currently, Heavy Metal Pollution Control technology can be mainly divided into such as cement solidification, plastic material packet of peripheral doses technology
Hold；Chemical remediation such as medicament stabilization technique；Biological prosthetic such as plant extraction, microorganism remediation.Due to industrial working heavy metal
The characteristics of pollution is in point pollution, i.e., there are contaminated and not contaminated situation, contaminated soil for same plant area different location
Its pollution level of earth is also not quite similar.Simultaneously, it is contemplated that the economic factors such as soil second development and utilization, it is desirable that soil remediation period
It cannot be too long.However, elution recovery technique can generate a large amount of ring waste, deals with improperly and will cause serious secondary pollution；
It is only rhizosphere range that plant extraction, which repairs depth, and repairing efficiency is long, it usually needs 5 years or more repair time；Microorganism is repaired
It is multiple more demanding to edaphic condition, limited by environmental factor larger, application range is relatively narrow.Therefore, elution technique, plant extraction,
The methods of microorganism remediation its repairing efficiency, effect are all difficult to meet the requirement of current heavy metal pollution place soil remediation.
Curing/stabilizing technology is mainly to pass through the occurrence patterns of change heavy metal in the soil to fix heavy metal, is hindered
Only its migration and diffusion in the environment, to reduce the murder by poisoning degree of heavy metal.Other opposite restorative procedures, solidification/stabilization
Change technology is widely used in heavy metal-polluted since cost is relatively low, easy for construction, repair time is short, environment long-term safety is good
Contaminate the improvement in place.Wherein, hot setting is treated as more common curing/stabilizing mode in recent years, as cement turns round
Kiln processing and brickization processing.The technology is to be fired into cement through high temperature for heavy-metal contaminated soil as a part of raw material
Or heavy metal can be not only fixed in stable mineral structure by brick, this process, eliminate the risk of heavy metal leakage,
The product being converted into can also be used as roadbed or construction material, realize the innoxious and recycling treatment of contaminated soil.
However during curing/stabilizing handles heavy-metal contaminated soil, when heat treatment, can generate a large amount of containing waving
The tail gas of hair property heavy metal and sour gas, direct emission can pollute atmosphere in air.
Summary of the invention
For the technical problems in the prior art, the purpose of this utility model is：Place heavy metal polluted soil is provided
The exhaust treatment system of earth abatement equipment prevents from causing secondary dirt for handling the tail gas for solidifying contaminated soil and generating in the process
Dye.
In order to achieve the above object, the utility model adopts the following technical solution：
The exhaust treatment system of place heavy-metal contaminated soil abatement equipment, including aerobic burner, spray column and tail
Gas processing system mobile platform, oxy combustion device and spray column are located on exhaust treatment system mobile platform, oxy combustion dress
It sets including sequentially connected blower, filter, combustor and combustion chamber, combustion chamber is equipped with catalytic bed, oxy combustion
The air inlet of device is used to connect the waste gas outlet of heat treatment system, the gas outlet of oxy combustion device and the air inlet of spray column
It is connected.
Further, combustion chamber uses three layers of insulation construction, from inside to outside respectively alumina fibre plate, aluminium oxide blanket and gold
Belong to shell.
Further, the air inlet of oxy combustion device is connected with offgas duct and combustion-aid air pipe.
Further, spray column is miniature light-weighted spray column.
Further, spray column is three layers of adverse current reduction of speed spray column.
Further, spray column is using potassium permanganate and limewash as spray liquid.
Generally speaking, the utility model has the following advantages that：
The exhaust treatment system of place heavy-metal contaminated soil abatement equipment, including aerobic burner, spray column and tail
Gas processing system mobile platform, oxy combustion device and spray column are located on exhaust treatment system mobile platform, oxy combustion dress
It sets including sequentially connected blower, filter, combustor and combustion chamber, combustion chamber is equipped with catalytic bed, oxy combustion
The air inlet of device is used to connect the waste gas outlet of heat treatment system, the gas outlet of oxy combustion device and the air inlet of spray column
It is connected.With the tail gas treatment device on exhaust treatment system mobile platform, can at the scene disposal field contaminated soil when will
Its exhaust gas generated when being moved to scene to calcining, heat treatment is handled, and avoids that secondary dirt will be caused in the in line air of tail gas
Dye.The exhaust treatment system of the miniaturization, although lightweight is minimized however filtered, oxidation, collect, the function of processing has
