Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing wastewater treatment, in particular to a high-efficiency oil-water separation device. Background Art

[0002] In the textile industry, in the textile fabric setting machine industry, a lot of waste gas is generated during production. The waste gas contains dust, cloth scraps, oil smoke and other substances that are harmful to the atmospheric environment. The oil mist evaporates in the atmosphere and is not easily soluble in water. It will not fall to the ground with rain. The waste gas needs to be treated by the setting machine oil fume treatment device later. The waste water directly discharged after passing through the setting machine oil fume treatment device contains a large amount of oil pollution. If the waste water is directly discharged to the outside, it will cause environmental pollution. Therefore, isolation operation is required when removing textile wastewater. After separating the oil pollution, the printing and dyeing wastewater can be recycled, which can save a lot of water resources.

[0003] The existing oil-water separation device mainly separates oil and water by the fluidity of water and oil. The fluidity of oil and water is low. However, in the existing oil-water separation device for printing and dyeing wastewater, the oil and water are often concentrated in one box for oil and water isolation treatment, which will lead to insufficient oil and water separation time, seriously affecting the oil and water separation effect. At the same time, the existing oil-water separation device cannot effectively recover the separated dirty oil or wax, which will cause the dirty oil or wax to accumulate in the oil-water separation box, thereby affecting the subsequent oil-water separation quality.
