An efficient energy-saving pyrolysis tank device for soil restoration

Abstract

An efficient energy-saving pyrolysis tank device for soil restoration is disclosed. The device includes a superconducting magnetic annular water jacket, a soil pyrolysis restoration tank body, a preheating water jacket, a high-frequency coil, a ceramic inner cylinder and a spiral blade. The ceramic inner cylinder is mounted inside the soil pyrolysis restoration tank body. The inside of the ceramicinner cylinder is a pyrolysis restoration cavity. A rotating shaft is mounted in the middle of the pyrolysis restoration cavity. The rotating shaft in the pyrolysis restoration cavity is welded to the spiral blade. The surface of the spiral blade is provided with a plurality of liquid spraying holes. The liquid spraying holes are communicated with a flow guide passage in the rotating shaft. The external wall of the ceramic inner cylinder is wound with the high-frequency coil. The superconducting magnetic annular water jacket is disposed outside the high-frequency coil. The inside of the superconducting magnetic annular water jacket is a hot-water cavity. Energy-saving effects of the device are good. The soil restoration cost is reduced. Agent spraying uniformity and sufficiency during soil restoration are improved. Heating and restoration effects on soil in the pyrolysis restoration cavity are improved, and the heating efficiency is high. The superconducting magnetic annular water jacket completely shields electromagnetic drifts.

Description

technical field [0001] The invention relates to the technical field of soil restoration equipment, in particular to a high-efficiency and energy-saving pyrolysis box equipment for soil restoration. Background technique [0002] With the acceleration of economic development and urbanization, the problem of land pollution caused by enterprise processing is becoming more and more serious. Due to the changes and adjustments in industrial structure and urbanization layout, many enterprises with serious pollution have been relocated one after another. Closed down, polluted sites continue to be produced. As an important place for human social production activities, soil is an indispensable natural resource that is difficult to regenerate. Untreated polluted sites contain a large amount of chemical pollution components. Once a large-scale outbreak occurs, it will cause incalculable losses to my country's sustainable development. Therefore, it is necessary to prevent soil pollution ...

Problems solved by technology

However, the gas phase extraction technology has a long running time and cannot meet the needs of undeveloped industrial polluted sites in the city; thermal desorption costs are high and cannot be used to treat large quantities of polluted soil; incineration and landfill technologies have a high risk of secondary pollution. High cost and limited throughput
