Temperature control system is adjusted power supply facilities, and then controls the heat condition of electric heating tube.
The operation principle of heated well is:
After energising, electric current flows through electric heating tube 2, and heating wire produces heat according to its rated power, and makes temperature in heated well
Degree is quickly increased to 400-500 DEG C.Heated well promotes heat to transmit to periphery with the temperature difference that surrounding formations environment exists, and makes soil
Heated with subsoil water.Under heating state, organic pollution reduces in soil surface adhesiveness and is easily separated from soil
Grain, increases its sendout and mobility in subsoil water and soil gas simultaneously.
Above-described embodiment is only preferred embodiment of the present utility model, limits protection model of the present utility model the most according to this
Enclose, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, protection of the present utility model all should be covered by
