Problems solved by technology
However, when using a rotary kiln to pyrolyze oily sludge, a large amount of oily sludge is directly put into the rotary kiln for pyrolysis, and there are the following problems: 1. The seal is not tight, causing the gas generated by pyrolysis to leak out and cause pollution; 2. Since a large amount of oily sludge in the kiln is piled together and it is not easy to burn through, the pyrolysis effect is poor and cannot be fully pyrolyzed

The invention provides a method for large-scale treatment of oily sludge. The method comprises the following steps: charging oily sludge to be pyrolyzed into a pyrolysis tank through a feeding / discharging port, and sealing the feeding / discharging port with a sealing cover; mounting a plurality of pyrolysis tanks filled with oily sludge on the annular track in front of the moving direction of the annular kiln body; the annular kiln body moves along the annular track to pyrolyze the oily sludge in the pyrolysis tank; gas generated by pyrolysis is collected to a gas collecting main pipe located under the ground corresponding to the annular rail through a gas collecting branch pipe connected to the top of the pyrolysis tank; and removing the pyrolysis tank subjected to pyrolysis from the annular track. The method for large-scale treatment of the oily sludge can realize large-scale continuous pyrolysis and is high in efficiency; the pyrolysis tank has good sealing performance so that pollution caused by leakage of gas generated by pyrolysis can be effectively prevented; the amount of oily sludge contained in each pyrolysis tank is relatively small, the oily sludge is easy to burn through, sufficient pyrolysis of the oily sludge is facilitated, and the pyrolysis effect is good.
Description
technical field [0001] The application relates to the technical field of pyrolysis treatment of solid waste containing organic pollutants in environmental protection, and in particular to a method for large-scale treatment of oily sludge. Background technique [0002] A large amount of oily sludge will be produced in the process of petroleum exploration and development, gathering, transportation, storage and transportation. The traditional incineration method is gradually being replaced by the pyrolysis treatment method due to secondary pollution and other problems. In the prior art, rotary kilns are often used to pyrolyze oily sludge. However, when using a rotary kiln to pyrolyze oily sludge, a large amount of oily sludge is directly put into the rotary kiln for pyrolysis, and there are the following problems: 1. The seal is not tight, causing the gas generated by pyrolysis to leak out and cause pollution; 2. Because a large amount of oily sludge in the kiln is piled toge...
