Description

Centrifuge with water removal function

The present invention relates to a centrifugal separator having a function of removing water with filtration of foreign substances, and more specifically, after condensing the water removing means built in the centrifuge, the water separated from the oil sprayed through the nozzle of the rotor is condensed. Relates to one centrifuge which allows for discharge via another route.

Generally, centrifugal filter is a device that separates / purifies / concentrates materials having different constituents or specific gravity by using centrifugal force.The centrifugal separator is an impurity of oil (lubricating oil or fuel oil) used in an engine or various mechanical devices. It is also used to filter.

1 is a cross-sectional view showing the structure of a conventional centrifuge.

The centrifuge shown in FIG. 1 is a centrifuge used to filter impurities in oil used in the engine.

The centrifugal separator includes a shaft 10 having an oil flow path 11 therein, a rotor 20 having a structure that rotates about the shaft 10, and a shaft together with the rotor 20. It has a structure that rotates around the (10) and the spindle tube 30 for injecting the oil flowing through the shaft into the rotor, the oil inlet 41 and the oil outlet 42 is formed and the rotor 20 inside It is comprised by the casing 40 accommodated in and receiving oil sprayed from the nozzle 21 of a rotor.

Such a centrifugal separator has a method of filtering various impurities in the oil by centrifugal force by receiving oil circulated by driving of a pump not shown, and more specifically, in the process of spraying oil through a nozzle provided in the rotor. Due to the reaction principle generated, the rotor rotates at a high speed and has a method of filtering impurities.

On the other hand, the centrifuge as described above can remove the impurities in the oil, but can not remove the water, so when constructing the oil filtration system using a centrifuge, using a separate oil and water separator to separate the water in the oil It is being removed.

However, the conventional oil and water separator is mainly used to heat the oil in order to separate the water in the oil, the oil-and-water separator of this heating method has a problem that consumes a lot of energy to heat the oil to the required temperature.

The centrifugal separator shown in FIG. 2 is capable of simultaneously removing impurities and water in the oil. In the process of rotating the rotor 50, impurities (A) and water (B) are formed at the inner edge of the rotor 50 by centrifugal force. Moisture separated from the oil is discharged through the flow path 51 provided in the rotor, and in the case of impurities (A) accumulated on the inner edge of the rotor, the impurity outlet 52 is opened when a predetermined amount is accumulated. It has a structure to discharge impurities to the outside.

This centrifuge has the advantage of removing water in the oil without using a separate oil / water separator, but water in oil is always in contact with water at the interface between water and oil in the rotor. There is a disadvantage that can not be removed completely.

The inside of the separation membrane 142 divides the inside of the rotor 140 into an upper space and a lower space so as to separate and discharge the filtered oil, and at the lower end, the filtered oil is introduced into the casing 110. The nozzle 141 which sprays is comprised.

Meanwhile, the shaft 120, the spindle tube 130, and the rotor 140 may be configured in the same manner as the shaft, the spindle tube, and the rotor used in a general centrifuge that is already widely used.

The blowing fan 150 circulates the air inside the casing 110 so that the water separated from the oil injected through the nozzle 141 flows in the structure circulating inside the casing 110, the casing ( 110 is disposed inside.

On the other hand, the blowing fan 150 may be configured to be integral with the motor, or connected to the motor 151 installed separately from the casing 110 to rotate.

The water removing means 160 is installed inside the casing 110 to condense moisture while contacting with the water flowing by the blowing fan 150.

The water removing means 160 may be composed of a known eliminator (Demister) for removing the droplets in the air flow, or a condenser consisting of a coil of low temperature refrigerant or cold water circulating, by using the eliminator When configuring the removal means 160, there is an advantage that the energy for driving the water removal means 160 is not additionally consumed.

On the other hand, the eliminator is composed of one or more mesh-like filter medium 161 formed by weaving the fine wire in the form of a mesh, as well known, the air containing moisture passes through the mesh-like filter medium (161) In the process of the inertial collision is the separation of air and water is made, the moisture is controlled to discharge the air.

The blower fan 150 and the water removing means 160 as described above may be fixed to the inside of the casing 110, and the air and the moisture inside the casing 110 may smoothly flow and contact the water removing means 160.
