Abstract

The invention discloses a method for incinerating petrochemical waste liquid based on oily liquid fuel. According to the method, oily liquid is used as combustion-supporting fuel, the petrochemical waste liquid is sprayed into a combustion area of a waste alkali incinerator in an atomization mode so as to burn in the condition that oxygen-containing gas is blown in, and the temperature of the combustion area is controlled to be 800 to 1200 DEG C; the feeding amount of the petrochemical waste liquid and the oily liquid meets the conditions that: the ratio of the amount of the petrochemical waste liquid per hour to the cross sectional area of a hearth of the combustion area of the waste alkali incinerator is equal to 0.8 to 1.5 t / h.m<2>, and the ratio of the amount of the oily liquid per hour to the cross sectional area of the hearth of the combustion area of the waste alkali incinerator is equal to 0.074 to 0.108 t / h.m<2>. According to the method, the reasonable burning load can be realized, the processing cost is reduced, the damage of excessive combustion load to the device is reduced, and the method is favorable for popularization and application of a waste liquid incineration technique in the industry.

Description

technical field [0001] The invention relates to a treatment method for petrochemical waste liquid, and more particularly relates to a method for incinerating waste cyclohexanone lye by using oily liquid fuel, belonging to the technical field of petrochemical industry. Background technique [0002] The petrochemical industry, such as the oxidation of cyclohexane to cyclohexanone, produces a large amount of high-concentration organic waste lye, making it up to standard treatment was once an environmental protection bottleneck for the industry's capacity expansion. In the late 1990s, Sinopec Baling Company successfully developed the waste alkali incineration technology based on the alkali recovery furnace method, which has the advantages of high COD removal rate and meets the national environmental emission standards after treatment, and has gradually become a waste alkali treatment process for cyclohexanone saponification. The mainstream technology has been put into applicatio...
