Problems solved by technology

[0004] However, using TPS technology to treat oily sludge can only volatilize organic pollutants with less than 30 carbons in oily sludge for recycling, while organic pollutants with more than 30 carbons (hereinafter referred to as C 30 + ) cannot be separated, resulting in intractable C-containing 30 + of solid pollutants
Contains C 30 + It is very difficult to treat the solid pollutants, and the conventional incineration technology cannot be used to completely burn them out, and it contains C 30 + The solid pollutants will cause long-term serious pollution to the environment and cannot meet the environmental protection standards of various countries.

Abstract

The invention provides a system for treating solid pollutant containing C30<+> and a system and method for treating oily sludge. Compared with the prior art, the system for treating oily sludge, provided by the embodiment of the invention, is characterized in that oily sludge is firstly fed into a hot phase decomposing device and is subjected to hot phase decomposition under the condition of heating by a combustion room to obtain solid pollutant containing C30<+>; and the obtained solid pollutant containing C30<+> is screened, ground and suspended and then is sent to the combustion room to be combusted so that the solid pollutant containing C30<+> is completely combusted and the environment pollution problem caused by the solid pollutant containing C30<+> is solved. The experiment result shows that the treated solid pollutant containing C30<+> is red and has a solid TPH value of less than 3000mg / kg.

Description

technical field [0001] The invention relates to the technical field of solid pollutant treatment, more specifically, relates to 30 + The treatment system of solid pollutants, the treatment system and method of oily sludge. Background technique [0002] Oily sludge, also known as TOC solid pollutants, is a solid pollutant produced in crude oil production, storage and transportation systems of oilfields and refineries and sewage treatment systems. Oily sludge generally has an oil content of 10% to 50%. In addition, it also contains a large amount of toxic substances such as benzene series, phenols, anthracene, and pyrene. If it is not treated, it will not only pollute the environment, but also cause waste of resources. [0003] At present, the following two technologies are mainly used for the treatment of oily sludge at home and abroad, one is complete incineration technology (referred to as TDU technology), and the other is thermal phase decomposition technology (referred ...
