Problems solved by technology

[0003] Nowadays, the oily sludge is huge in volume. If it is discharged without treatment, it will not only occupy a large amount of cultivated land, but also cause pollution to the surrounding soil, water, and air. The viscosity of the mud is high, which can easily cause the clogging of the filter cloth, which greatly affects the dewatering efficiency of the oily sludge

Abstract

The invention discloses a squeezing dewatering and oil extraction apparatus for oil-containing sludge treatment, wherein the apparatus comprises a first adjusting device, a dewatering device and a second adjusting device. In the prior art, oil-containing sludge has an oil content of 10-50% and a water content of 40-90%, such that the oil-containing sludge has large viscosity; and when the oil-containing sludge is subjected to actual belt pressure filtration dewatering, the larger viscosity of the oil-containing sludge can reduce the dewatering efficiency while the material can clog the filtering cloth. In order to solve the problem in the prior art, the technical scheme of the present invention comprises that a first adjusting device is arranged before a dewatering step, and can effectively reduce the viscosity of oil-containing sludge so as to further improve the belt pressure filtration dewatering efficiency while improve the dewatering effect. According to the present invention, thetechnical scheme has characteristics of reasonable structure design and simple operation, and can effectively achieve the squeezing dewatering and extraction of oil-containing sludge, improve the dewatering efficiency of oil-containing sludge, avoid the sludge clogging, and achieve high practicability.

Description

technical field [0001] The invention relates to the technical field of oily sludge recovery, in particular to a dehydration and oil extraction device for oily sludge treatment. Background technique [0002] Oily sludge refers to sludge mixed with heavy oil such as crude oil, various refined oils, and residual oil. Oily sludge is not inherent in nature, but due to various accidents, improper operation, Old, damaged, corroded equipment causes crude oil and refined oil to escape, leak, drip, leak, leak to the ground, deposit on the bottom of oceans, lakes, rivers, and mix with soil, water, etc. to form oil and soil. water, even in mixtures with other pollutants such as Oily sludge is harmful to the human body, plants and aquatic organisms. The oil and gas evaporated in the air can irritate the skin, eyes and respiratory organs, and make the land lose the function of plant growth. It is difficult to deal with and repair. It is the main oil and petrochemical industry. one of t...
