A kind of oil sludge modifier and method for converting oil sludge into regenerated solid fuel by modifying the same

Abstract

The invention discloses an oil sludge modifier. The formula comprises the following components in percentage by mass: 10-40% of a methacryloyloxyethyl trimethyl ammonium chloride copolymer, 5-30% of a dimethyl diallyl ammonium chloride and acrylamide copolymer, 15-30% of sodium carboxymethylcellulose and 25-35% of volcanic ash. The previous components are uniformly mixed according to a ratio so as to obtain the oil sludge modifier. Meanwhile, the invention further discloses a method for performing modified treatment on oil sludge to transform into solid fuel by utilizing the oil sludge modifier. The oil sludge modifier disclosed by the invention is simple in preparation process, low in cost and low in energy consumption, the solid fuel is formed by treating the oil sludge by using the oil sludge modifier, and secondary mudding is avoided. On the one hand, reduction, harmlessness and stabilization of oil sludge treatment can be realized; on the other hand, recycling during sludge treatment is realized.

Description

Technical field [0001] The invention relates to the field of sludge treatment, in particular to a sludge modifier and a method for converting the modified sludge into a new type of regenerated solid fuel. Background technique [0002] With the rapid development of the petroleum industry, a large number of by-products have appeared in the petroleum industry, and the sludge urgently needs to be effectively treated. Oil sludge contains water, sediment, residual crude oil, benzene series, phenols and other odorous toxic and harmful substances, and a large number of pathogenic bacteria, parasites and other harmful substances. According to the "Solid Waste Environmental Pollution Prevention and Control Law" and the "List of Hazardous Wastes", the sludge needs to be harmlessly treated and used as resources. [0003] At present, the domestic sludge treatment methods probably include: incineration, coking, landfill, extraction, pyrolysis, solidification, chemical demulsification and biolog...

AI Technical Summary

Problems solved by technology

The existing technology still has problems such as high technical treatment cost, long process flow, complicated process operation, unsatisfactory treatment effect, low resource utilization efficiency, easy to produce secondary pollution, limited treatment capacity, etc.

[0004] Fundamentally speaking, the existing technology has not really achieved the harmless treatment and resource utilization of oil sludge. Although the existing coking methods, extraction methods, pyrolysis methods, etc., can recycle the useful substances of oil sludge to a certain extent , but there is still re-pollution and secondary treatment of waste residues in the later stage, which increases the cost and environmental hazards; in terms of harmless treatment, the existing incineration, landfill, solidification and other technologies can solve a large amount of sludge, but It will pollute the environment again and require more cost
