Description

Three-stage high-vacuum oil filtering system

Technical Field

The invention relates to the field of lubricating oil production and processing, in particular to a three-level high-vacuum oil filtering system.

Background

The vacuum oil filter is designed according to the principle that the boiling points of water and oil are different, and comprises a prefilter 4, a vacuum heating tank, an oil pump 18, a filtering device, a condenser (namely a condenser), a vacuum pump 17 and the like. The vacuum pump 17 pumps the air in the vacuum heating tank out from the gas phase outlet of the vacuum heating tank to form vacuum, and the external oil passes through the prefilter 4 under the action of atmospheric pressure to remove larger particles and then enters the heating zone in the vacuum heating tank. The heated oil is separated into semi-fog by the flying rotation of the spray wings, the water in the oil is rapidly evaporated into steam, the mixed air is continuously sucked into the condenser by the vacuum pump 17, the steam entering the condenser is cooled and then returns to water to be discharged, the oil in the vacuum heating tank is discharged into the fine filter 19 by the oil discharge pump 18, and the fine particle impurities are filtered out by the oil filter paper or the filter element, thereby completing the whole process of rapidly removing the impurities, water and gas in the oil by the vacuum oil filter, and discharging clean oil out of the machine from the oil outlet. The three-stage vacuum firstly aims at realizing 'large pumping speed', namely efficiency, and rapidly increasing the vacuum degree; and secondly, the area of vacuum flash evaporation is increased, so that the emulsion is effectively and quickly broken, and the moisture is removed. In the existing three-stage vacuum oil filtering system in the market at present, the oil is separated into semi-vaporific by adopting a spray wing or a spray head, so that the water transpiration is realized into water vapor. However, the medium is dirty oil, so the spray wings or the spray heads are easily blocked by dirt, the filtering effect is affected, and the cleaning is not easy after the blockage occurs; the oil spraying direction of the spray head is fixed, the spraying channels of the spraying wings are few, and the spray head and the spraying wings cannot well separate oil into mist, so that oil-water separation is realized; the spray wing or the spray head is composed of a plurality of additional parts, including bolts and nuts, and the parts are easy to fall off when rotating at high speed, thereby causing secondary pollution to oil bodies; in the condensation process, generally adopt the two-stage water-cooling, the condenser adopts simple structure's shell and tube heat exchanger, for making the air current obtain great cold volume, the shell layer is walked to the design gaseous phase, and the cooling water walks the tube side, nevertheless so sets up, and the air current has accumulative impact to the heat exchange tube of tube side, uses for a long time, and the heat exchange tube is fragile, influences the heat transfer effect.
