Description
Technical field
The utility model belongs to oil pollution processing technology field, is specifically related to a kind of oil-polluted soils prosthetic device based on thermal desorption.
Background technology
The oil pollution of soil is one of global environmental problem.Oil in exploitation, store, transport, leakage in processing and application process and discharge all can to environments, and in trend serious gradually.Oil-polluted soils not only can affect soil quality, suppresses plant growth, also affects health by food chain.Can be divided into dystopy and in-situ immobilization two kinds of methods for oil-polluted soils reparation at present, showering refers to and soil to be repaired is excavated out a kind of method of carrying out strange land process, repair speed, but excacation amount is huge; In-situ immobilization is then repaired in pollution former address, and eliminate the operation of excavation, not spoiled soil original appearance, cost is lower, is therefore following main stream approach of repairing.
Chinese patent CN 102513347 A(application number: 201110434116.2, the applying date: 2011.12.22) disclose the method that soil vapor extraction technology governance contaminated soil is combined in the strengthening of a kind of in-situ heat, the method needs heated well and extraction well, first by heated well, soil is heated, again by bleeding to extraction well, making the gas extraction containing organic pollution enter exhaust treatment system and processing.The method quantities is comparatively large, needs electrical network to provide power supply simultaneously, can not carry out operation in remote districts.
Summary of the invention
The utility model provides a kind of oil-polluted soils prosthetic device based on thermal desorption to overcome order the deficiencies in the prior art, this device have quantities little, be convenient to the advantages such as transport, can in operation from far-off regions, solve oil pollution problem.
For achieving the above object, the technical scheme taked of the utility model is as follows:
The utility model provides a kind of oil-polluted soils prosthetic device based on thermal desorption, comprise electric power system, heating system, conduction-convection problem, seal closure, oil gas output system and caisson, described electric power system is connected with heating system, heating system is connected with conduction-convection problem, seal closure is placed in above conduction-convection problem, seal closure is provided with exhaust outlet, and the entrance of oil gas output system is connected with seal closure by exhaust outlet, and the outlet of oil gas output system is connected with caisson.
According to the above-mentioned oil-polluted soils prosthetic device based on thermal desorption, described oil gas output system is vavuum pump.
