Blade type vacuum oil-water separating device

Abstract

The invention discloses a blade type vacuum oil-water separating device and belongs to mineral oil purification equipment. The device mainly comprises a vacuum extraction port, a liquid-gas partition board, an oil inlet, an oil-water distributor, a vacuum chamber, a drive blade, a driven blade, a transmission mechanism and an oil discharge outlet. The device is characterized in that the vacuum chamber is rectangular, the vacuum extraction port and the oil inlet are arranged on the upper portion of the vacuum chamber, the liquid-gas partition board is arranged between the vacuum extraction port and the oil inlet, the oil inlet is connected with the oil-water distributor, the drive blade is installed below the oil-water distributor, the drive blade is composed of a group of two parallel dragon graining blades, the drive blade transmit motion to the driven blade through the transmission mechanism, the driven blade is composed of upper, middle and lower groups of two parallel dragon graining blades, and oil liquid which is subjected to water removal and the oil discharge outlet are arranged on the lower portion of the driven blade. The blade type vacuum oil-water separating device has the advantages that the structure is novel, the drive blade and the driven blade enable the oil liquid and steam to form two channels, the evaporation area is increased, the workload of the vacuum pump is reduced, the oil-water separation is stable and thorough, the separation efficiency is high, and the like.

Description

technical field [0001] The invention relates to a blade-type vacuum oil-water separation device, which belongs to mineral oil water removal and purification equipment, in particular to a purification device that utilizes blades to realize high-efficiency vacuum evaporation of oil and water and separate water vapor. Background technique [0002] Vacuum oil-water separation device is a special equipment suitable for water removal, impurity removal and waste oil purification of cutting oil, engine oil in the field of machinery manufacturing, transformer oil, steam turbine oil, hydraulic oil and other industrial oils in industrial and mining enterprises. The technical feature is that the oil-water mixture enters the atomizer from the top of the circular tank under the action of negative pressure (vacuum pump), and then sprays on the separation tray. The common separation tray is composed of multi-layer folded sheets. Relying on its own gravity and vacuum pressure on the separati...

AI Technical Summary

Problems solved by technology

[0003] It can be seen that the key structure of the common vacuum oil-water separation device to realize oil-water separation is the atomizer and the separation tray. After the oil passes through the atomization distributor from the top of the vacuum tank, its atomization effect has a great influence on the oil-water mixture entering the separation tower. The separation efficiency of the plate plays a key role. When the atomization effect is good, the oil and water can be effectively separated in the middle and upper part of the separation plate. Otherwise, the water in the oil is easily "wrapped" by the descending oil. to efficient evaporative separation

In addition, the "spreading" effect of the fixed separation tray in the tank on the oil-water mixture is limited, and it changes with the change of the movement state of the mixture. Mixing with the oil will not achieve the purpose of purifying the oil; and the water vapor in the lower part of the separation tray is extremely difficult to pass through, which increases the load on the vacuum pump and reduces the vacuum purification efficiency, often requiring multiple cycles of heating or purification. Can not meet the actual engineering needs
