Combination treatment system of oil sludge cracking and thermal desorption of polluted soil

Abstract

A combined treatment system for oil sludge cracking and thermal desorption of polluted soil, comprising: an oil sludge thermal cracking treatment system and a polluted soil thermal desorption treatment system. By this, thermal cracking treatment of organic sludge and oil sludge and thermal desorption treatment of organically polluted soil can be carried out at the same time, and the volatile organic components separated from them can be recovered, heated by combustion, and provided as thermal cracking reaction and heat The heat source required for the desorption reaction can effectively save energy, thereby reducing 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

In the treatment of organically polluted soil, 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 small areas in Taiwan. In densely populated areas, thermal desorption treatment also consumes a lot of energy and is quite expensive in terms of treatment costs. Therefore, there is room for improvement in the treatment of conventional oil sludge, organic sludge and organic-contaminated soil.
