Prestage vacuum oil-water separating device

Abstract

The invention discloses a prestage vacuum oil-water separating device, belonging to a mineral oil purifying device, mainly comprising a vacuum exhaust port, an oil inlet, a gas conduit, an atomization distributor, a prestage vacuum chamber, a prestage separating tray, oil-water distributors, a main vacuum chamber, a main separating tray, an oil limit switch and an oil discharge outlet, wherein the upper portion of the main vacuum chamber is provided with the prestage vacuum chamber and the vacuum exhaust port, the oil inlet is arranged above the prestage vacuum chamber, the lower portion of the oil inlet is provided with the atomization distributor; the central portion of the prestage vacuum chamber is provided with the prestage separating tray, the bottom of the prestage vacuum chamber is provided with the uniformly distributed oil-water distributors, and the side surface of the prestage vacuum chamber is provided with the gas conduit; the gas conduit passes through the bottom of the main separating tray and is arranged above the maximum liquid level of oil. According to the invention, the structure is novel, the evaporation area is enlarged, the working load of the vacuum pump is reduced, and the advantages of stable and thorough oil-water separation, high separation efficiency, etc. are achieved.

Description

Technical field [0001] The present invention involves a front -level vacuum oil -water separation device, which is a mineral oil -de -purification equipment. It is specifically a purification device with high -efficiency vacuum evaporation and water in the first -level level. Background technique [0002] The oil contains water, which will not only have a great impact on the physical and chemical properties of the oil itself, but also affect the normal work of the entire system.The vacuum oil and water separation device is a special equipment used in the field of cutting oil, motor oil, turbine oil, hydraulic oil and other industrial oils in the field of mechanical manufacturing.The technical characteristics of the oil and water hybrid fluid Enter the atomizer from the top of the vacuum tank under the action of negative pressure (vacuum pump), spray it on the separated tower, and the oil and water rely on its own gravity and vacuum pressure on the separation tower.Follow the "twi...
