Description

Technical Field

[0001] The present invention relates to an efficient oil purification system. Background Art

[0002] With the rapid development of the power industry, the units are becoming increasingly large-scale and standardized, thus having higher requirements for the quality of lubricating oil.

[0003] Water in the oil can emulsify the lubricating oil, accelerate the oxidation of the grease, and increase the corrosion of the machinery by low-molecular organic acids. At the same time, water in the oil will change the flow performance of the oil flow and reduce the economic efficiency of the unit operation. In order to reduce the content of water and other impurities in the lubricating oil, the used lubricating oil needs to be filtered twice before it can be used again.

[0004] Atomizing the oil liquid can increase the surface area of the water in the oil for vacuum evaporation, thereby improving the evaporation capacity of the vacuum oil purifier. In actual use, in order to reduce the viscosity of the oil liquid and enhance the atomization effect, it is often necessary to preheat the oil liquid before atomization, generally heated to about 60°C. After atomization, the water vapor quickly evaporates and is discharged from the steam outlet to achieve further purification of the oil liquid. However, the existing atomizing oil purifiers often do not treat the discharged water mist, thus causing environmental pollution, affecting the cleanliness of the working environment, and the water mist often contains oil, which also brings the pressure of cleaning. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned deficiencies of the prior art and propose an efficient oil purification system.

[0006] An efficient oil purification system includes a centrifugal oil purifier, a heater, and an atomizing oil purifier connected in sequence; the heater is composed of a plurality of heat exchange tubes, the heat exchange tubes are embedded in a heat exchanger, and several hot water flow channels are provided in the heat exchanger. The steam outlet at the top of the atomizing oil purifier is connected to a condenser, a waste water collection cylinder is provided at the bottom of the condenser, the condenser is embedded in a cold exchanger, and several cold water flow channels are provided in the cold exchanger. The outlet of the cold water flow channel is connected to the inlet of the hot water flow channel through a reheating device, and the inlet of the cold water flow channel is connected to the outlet of the hot water flow channel through a recooling device.

[0007] By setting the specific lengths of the pipelines on the recooling device and the reheating device, it is ensured that after a certain time of heat exchange, the cooling balance between the condenser and the heater can be achieved on the premise of closing the recooling device and the reheating device.

[0008] Extending the pipeline length means increasing the heat dissipation capacity, and reducing the pipeline length means enhancing the heat preservation capacity. The specific length is calculated and confirmed according to the ambient temperature at the processing site.

[0009] Preferably, an oil tank is provided at the bottom of the centrifugal oil purifier.

[0010] Preferably, a vacuum pump is provided at the purified oil outlet at the bottom end of the atomizing oil purifier.

[0011] Preferably, a plurality of arc-shaped fins are provided on the back of the condenser. The arc-shaped fins are symmetrically arranged. A semi-circular depression is provided on the inner surface of the arc-shaped fins. The cold water flow channel is annularly embedded in the semi-circular depression of the arc-shaped fins.

[0012] Preferably, an electromagnetic valve is further provided between the centrifugal oil purifier and the heater.

[0013] Preferably, the heat exchange tube is made of hard aluminum alloy.

[0014] Preferably, the surface of the heat exchange tube is provided with a knurled surface.

[0015] Preferably, the pipe wall materials of the hot water flow channel and the cold water flow channel are both brass.

[0016] Preferably, an atomizing nozzle is provided at the top end of the atomizing oil purifier. An oil storage cavity is provided inside the atomizing nozzle. An eccentric wheel is provided in the middle of the oil storage cavity. The eccentric part of the eccentric wheel is connected to a motor through a rotating shaft. A plurality of pressure pumps are arranged in a circumferential array on the outer ring of the oil storage cavity. The end of the pressure pump is provided with an atomizing plate. A plurality of micropores are provided on the atomizing plate. A piston and a push rod are provided inside the pressure pump. One end of the push rod is connected to the middle of the piston, and the other end abuts against the eccentric wheel. A one-way valve is provided on the surface of the piston.

[0017] Preferably, the one-way valve is an L-shaped elastic block. A through hole is provided on the piston. The elastic block is located on the side of the piston close to the atomizing plate. The long side of the elastic block abuts against the orifice of the through hole, and the short side of the elastic block is embedded in the piston.

[0018] Beneficial effects:

[0019] 1. By adding an atomizing oil purifier behind the traditional centrifugal oil purifier, the quality of the lubricating oil can be effectively improved, the water content of the purified lubricating oil can be reduced, and thus the service life of the equipment can be extended.

[0020] 2. By installing a condenser and a waste water collection cylinder, the discharged water vapor can be effectively condensed into water droplets and discharged, rather than directly discharged into the air, thereby reducing environmental pollution and improving the cleanliness of the working environment.

[0021] 3. Further, in order to save energy, the heater for preheating the oil liquid and the condenser for cooling the steam are organically integrated. The heat between the two is exchanged through the cold heat exchanger and the hot heat exchanger, which can effectively save energy. Description of the drawings
