Foam elimination device for vacuum oil purification

Abstract

The invention discloses a foam elimination device for vacuum oil purification, which comprises guide plates, stainless steel meshes, chromatography devices and a bracket, wherein the bracket is successively connected with the guide plates, five layers of stainless steel meshes and five sets of chromatography devices from top to bottom; the guide plate is made of a stainless steel plate of which the thickness is 1.5mm; a plurality of holes of which the diameter is 3mm are processed in the plate; the diameter of holes in the stainless steel meshes is 1mm; space between every two layers of stainless steel meshes is 10mm; each chromatography device is formed by successively connecting an upper guide plate, a high-elastic fiber ball and a lower guide plate; the space between the upper guide plate and the lower guide plate is 30mm; the middle is provided with a high-elastic fiber ball of which the diameter is 10mm; and the space between every two layers of chromatography devices is 20mm. The foam elimination device for vacuum oil purification has the advantages of reasonable and advanced structure, foam generated in a vacuum tank in the vacuum oil purification processing process can be effectively eliminated, and the safety and the environment protection in the vacuum oil purification processing process are greatly improved.

Description

technical field [0001] The invention relates to a foam elimination device for vacuum oil purification, which belongs to the technical field of oil purification. Background technique [0002] At present, in the process of vacuum oil purification, when the processed oil enters the vacuum tank under negative pressure from the normal pressure state, due to the change of pressure and the influence of impurities in the oil (gas, liquid and solid impurities) Affected by various factors such as temperature and temperature, a large number of bubbles will be generated after the treated oil enters the vacuum tank. Because it cannot be eliminated, the foam will grow rapidly within the height of the vacuum tank. When the height of the foam reaches the vacuum pump When the air suction port of the air pipeline is used, the foam will be drawn out from the air suction line by the vacuum pump and discharged from its exhaust port by the vacuum pump. After the foam is discharged by the vacuum p...

[0002] At present, in the process of vacuum oil purification, when the processed oil enters the vacuum tank under negative pressure from the normal pressure state, due to the change of pressure and the influence of impurities in the oil (gas, liquid and solid impurities) Affected by various factors such as temperature and temperature, a large number of bubbles will be generated after the treated oil enters the vacuum tank. Because it cannot be eliminated, the foam will grow rapidly within the height of the vacuum tank. When the height of the foam reaches the vacuum pump When the air suction port of the air pipeline is used, the foam will be drawn out from the air suction line by the vacuum pump and discharged from its exhaust port by the vacuum pump. After the foam is discharged by the vacuum pump, it will return to the state of oil under normal pressure, and the oil will be discharged. Afterwards, it will cause environmental pollution; threaten the safety of staff; increase processing costs and production costs; serious will cause fire threats to equipment and personal safety or even greater safety accidents

At present, there is no good solution in the process of vacuum oil purification at home and abroad, and only negative control methods can be used to work, so that there are great hidden dangers in the vacuum oil purification work.
