Oily sludge thermal oxidation skid-mounted treatment device

Abstract

The invention relates to an oily sludge thermal oxidation skid-mounted treatment device which comprises a base and a housing mounted on the base, wherein a rotary kiln is mounted on the base in the housing through a rotating mechanism; the rotary kiln has a transversely arranged circular truncated cone-shaped cross section; a feed opening communicated with the outside of the housing is formed in one end, where the hole diameter is small, of the rotary kiln; a discharge opening is formed in one end, where the hole diameter is large, of the rotary kiln; the discharge opening is corresponding to a burner and an air lower mounted on the housing; a first ash discharge opening and an air outlet communicated with the outside are formed in the rotary kiln and at the position close to one end where the hole diameter of the rotary kiln is small; a second ash discharge opening is formed in the rotary kiln and at the position close to one end where the hole diameter of the rotary kiln is large; a plurality of knocking hammers are arranged in the rotary kiln; every two of the knocking hammers fall into one group and arranged on the inner wall of the rotary kiln in a symmetric manner. The oily sludge thermal oxidation skid-mounted treatment device has the advantages as follows: the rotary kiln is adopted as the main body, oil sludge is in full contact with a fire source when rotating in the rotary kiln, and the transportation and maintenance are convenient.

Description

technical field [0001] The invention relates to a thermal oxidation skid-mounted treatment device for oily sludge, which is especially suitable for the oil field environment with scattered blocks and poor ground environmental conditions. Background technique [0002] With the continuous development of the petroleum industry, all kinds of oily sludge produced in the process of petroleum production and refining, such as waste oil-based mud, large tank sedimentation sludge, oily sludge produced in sewage treatment, and oily sludge produced in oil emergencies Sludge and the like also increase accordingly. Different types of sludge have complex properties, large differences in oil content, difficulty in treatment, and high treatment costs. If they are not treated, they will be landfilled or piled up on the spot, which will not only waste limited oil resources, but also cause serious pollution to the surrounding environment. At present, major domestic oil production and petrochem...

Problems solved by technology

However, incineration has always had the following problems: (1) high investment and operating costs; (2) difficult plan implementation; (3) fly ash, slag and flue gas are produced during the incineration process

The coking method for oily sludge treatment does not require high oil content in oily sludge, but the equipment required for the whole process is more complicated and the investment is larger
