Oil mud cracking and polluted soil thermal desorption combination treatment system

Abstract

The invention relates to an oil mud cracking and polluted soil thermal desorption combination treatment system, which comprises an oil mud thermal cracking treatment system and a polluted soil thermal desorption system. With the oil mud cracking and polluted soil thermal desorption combination treatment system of the present invention, the organic sludge and oil mud thermal cracking treatment and the organically-polluted soil thermal desorption treatment can be simultaneously performed, and the separated volatile organic ingredients are recovered and are subjected to combustion heating so as to be adopted as the heat source required by the thermal cracking reaction and the heat desorption reaction, such that the energy sources are effectively saved so as to reduce the treatment cost.

Description

technical field [0001] The invention relates to a combined treatment system of oil sludge cracking and thermal desorption of polluted soil, especially a thermal cracking treatment of petrochemical waste such as organic sludge and oil sludge and thermal desorption treatment of organic polluted soil at the same time, and can be separated by using The volatile organic components provide the heat energy required for the reaction to effectively save energy and reduce the treatment cost of the combined treatment system of oil sludge cracking and thermal desorption of polluted soil. Background technique [0002] According to the long-term development of my country's petroleum refining industry and petrochemical industry, it has made considerable contributions to energy independence and economic prosperity. However, the waste pollution from petroleum refining and petrochemical industries also has a great impact on the environment. [0003] For example: in the storage tanks set up b...

AI Technical Summary

Problems solved by technology

However, the simple incineration process consumes a lot of energy and produces a large amount of waste gas; while the cracking treatment technology can effectively recover part of the energy and stabilize the sludge, so it has become a technology that urgently needs to be developed

For the treatment of organically polluted soil, the thermal desorption treatment technology has the best efficiency and fast speed. It is a technology with high energy efficiency and low impact on the environment, which is very suitable for the small population in Taiwan. However, thermal desorption treatment also consumes a lot of energy and is quite expensive in terms of treatment costs. Therefore, there are still areas to be improved in the treatment of conventional oil sludge, organic sludge and organic-contaminated soil.
