Description

Turbo blower packing with cooling structure that improves turbo blower efficiency

The present invention relates to an enclosure of a turbo blower formed with a cooling structure in which the efficiency of the turbo blower is improved. After cooling the heat generated from the device while passing through the outside of the device, it flows into the turbo blower and is used as compressed air for the process to improve the compression ratio. It relates to the enclosure of the formed turboblower.

As is well known, a turbo blower refers to a device that uses the rotational force of a motor to rotate an impeller at a high speed to introduce air from the outside and blow the discharged air using this. The discharged air is supplied to a wastewater purification plant or a treatment plant, and the discharged air flows into the purified water to improve the dissolved oxygen amount in the purified water, thereby increasing the purification efficiency.

A conventional turbo blower is provided inside an enclosure or housing, and introduces air inside the enclosure or housing to generate discharge air. However, since the temperature of the air inside the enclosure is increased by heat generated while various devices such as a turbo blower provided inside the enclosure are driven, the air flowing into the turbo blower contains high-temperature heat.

As high-temperature air flows into the turbo blower, there is a problem in that the compression efficiency of the turbo blower is reduced, and the temperature of the compressed air used for the process is also discharged at a relatively high temperature.

On the other hand, the turbo motor is formed of a stator core, a coil, etc. on which silicon steel plates are stacked, and a stator that receives power to generate magnetic force, and a rotor that rotates by magnetization of the stator. In particular, a high-speed turbo motor Since the AC converter may be used for high-speed rotation, electrical heat may inevitably be generated. If such electrical heat is not removed, the life of the turbo motor may be shortened, and a fire accident due to heat may occur.

Accordingly, as a cooling method for cooling such heat, an air cooling method in which the motor is cooled by circulating air, a water cooling method in which the motor is cooled by circulating cooling water, and a cooling method using refrigerant gas and air are mainly used.

In the air-cooling cooling method, a cooling fan is provided on one side of the motor or a separate circulation fan is provided to cool the motor by supplying air. When the temperature of the environment is high, since the motor is cooled with high-temperature air, there is a problem in that the cooling efficiency is lowered.

In addition, the water-cooled cooling method has a higher heat absorption rate than air, but a heat exchanger, a water tank, a pipe, etc. must be separately provided to cool the water that has absorbed heat, and most of the components of the turbo motor use power. There is a problem that a large accident may occur due to water leakage.

The heat exchanger 103 is formed on one side of the enclosure body 101 so that external air is introduced into the blowing fan 202 , and the heat exchanger 103 using the air introduced by the blowing fan 202 . After condensing the gas refrigerant discharged from the turbo blower 201 may be discharged to the outside.

In addition, the air used to convert the gaseous refrigerant into the liquid refrigerant is cooled by the turbo blower 201 and its parts and heat generated in the compressed air flow path, and then is blown through the heat exhaust hole 105 . discharged to the outside of the enclosure.

The windbreak 104 is formed on the upper surface of the enclosure body 101, and the windshield 203 is connected, and the compressed air generated in the turbo blower 201 is discharged to the outside through the windbreak 104. .

The turbo blower 201, the heat exchanger 103, the blower fan 202, the pump 205, and the air flow path generated by the turbo blower 201 provided in the housing body 101 are emitted from the configuration. When the generated heat is not discharged to the outside and stays inside the enclosure body 101, the temperature of the configuration of the turbo blower 201, etc. can be further increased, so that the operating efficiency can be reduced, and at the same time, it is discharged through the windbreak. The temperature of the compressed air rises.

In order to prevent this, a plurality of heat discharging holes 105 are provided on the upper surface of the enclosure body 101 to dissipate internal heat to the outside through the air introduced by the blower fan 202 .

The first space 200 is formed on one side of the main body 100 and is provided with a turbo blower 201 and a heat exchanger 103 to generate compressed air, and a turbo blower 201 and a heat exchanger 103 are provided. ), a blower fan 202 , a windbreak pipe 203 , a receiver 204 , a pump 205 , and the like.

The turbo blower 201 uses a refrigerant as a coolant and generates discharged air, and serves to generate compressed air using the turbo motor 201a and flow the generated compressed air to a windshield.

Here, the turbo motor 201a is provided so that the stator of the turbo motor 201a is cooled using a refrigerant, the stator may be immersed in the refrigerant, and the refrigerant introduced into the stator through the refrigerant passage. While moving, the stator can be cooled.

The refrigerant partially vaporized by cooling the stator is discharged to the outside of the turbo motor 201a, circulated along the heat exchanger 103, the receiver 204, the pump 205, etc. 201a) and can be used again to cool the turbomotor 201a.

On the other hand, the refrigerant used to cool the turbomotor 201a is vaporized into a gas above a certain temperature and liquefied into a liquid below a certain temperature, and materials such as insulating, non-flammable, non-explosive, etc. may be used. Refrigerants such as R-22 and R-134a may be used, and CO2 refrigerants with flammability, explosiveness, etc. cannot be used.

R-22 is a kind of Freon refrigerant, and the refrigeration ability is the best among Freon refrigerants, and it can be widely used from small to large equipment. In particular, it is mainly used for reciprocating air conditioners and the like, and can also be used for low-temperature refrigeration equipment. However, Freon refrigerant destroys the ozone layer and affects global warming, and when moisture penetrates, it is corrosive to metals.

In addition, 134a is a refrigerant developed as a replacement refrigerant for R-12, and has colorless, transparent, non-flammable properties. It is mainly used for refrigerators and automobile air conditioners. It does not contain chlorine in its molecule, so it has no ozone depletion potential, but has a high global warming potential.

In general, a turbo blower generates compressed air using internal air such as a housing (or enclosure) provided with a turbo blower. Inside the housing (or enclosure) provided with the turbo blower, high-temperature air flows due to the heat emitted from the configuration of the turbo motor, etc., and the high-temperature air flows into the turbo motor. It rises, which not only lowers the compression ratio of the turbo blower, but also discharges compressed air at a high temperature. In this case, the temperature of the exhausted compressed air is a high temperature of about 100 to 110 degrees. It can rise and disappear.

However, in the turbo blower 201 according to the embodiment of the present invention, fresh air introduced from the outside is supplied to the turbo motor ( 201a) to form compressed air.

In addition, since the refrigerant used to cool the turbo motor 201a is vaporized to become gaseous refrigerant, air directly introduced from the outside through the heat exchanger 103 to condense it is heat-exchanged using the turbo motor 201a. Since it can be cooled, the air heated by the configuration inside the enclosure body 101 is not used during the process of generating the discharge air.

As described above, the turbo blower 201 according to the embodiment of the present invention generates compressed air by directly using the air introduced to the outside and cools the vaporized refrigerant, so that while the turbo motor 201a is operating, it is self-contained. The temperature rise of the can also be reduced, it is possible to lower the temperature of the compressed air to be produced.

Accordingly, the discharged air generated by the turbo blower 201 is discharged at a temperature of about 70 to 75 degrees, and supplied to purified water of a wastewater purification plant, etc., to supply a sufficient amount of oxygen to purified water, etc., so that the amount of dissolved oxygen in purified water is reduced can increase

The heat exchanger 103 is configured such that air is introduced from the outside in contact with one side of the main body 100 , and may receive air through a blower fan 202 formed on one side of the body 100 .

The heat exchanger 103 cools the refrigerant vaporized while passing through the turbomotor 201a and liquefies the refrigerant into a liquid refrigerant, and may include a heat exchange tube 202a, a heat exchange fan 202b, and the like.

The heat exchange tube 202a may change phase into a liquid refrigerant as the heat of the refrigerant is dissipated by the heat exchange fan 202b while the gaseous refrigerant passes. For efficient heat exchange, the heat exchange tube 202a is It may be provided as a microchannel or the like.

The existing cooling system converts a low-temperature and low-pressure liquid refrigerant into a high-temperature and high-pressure gas through a compressor, converts it to a high-temperature and high-pressure gas through a condenser, and then converts it to a low-temperature, low-pressure liquid through an expansion valve, etc. use.

However, in the present invention, the refrigerant flows into the turbomotor 201a to cool the turbomotor 201a, and the temperature rises by about 2 to 10 degrees, and the phase change to a liquid state by the heat exchanger 103 serving as a condenser Therefore, the role of the compressor, the expansion valve, etc. can be omitted.

The refrigerant having a temperature of about 2 to 10 degrees while passing through the turbomotor 201a may decrease in temperature by about 2 to 10 degrees while passing through the heat exchange tube 202a.

The heat exchange fan 202b supplies air to the refrigerant passing through the heat exchange tube 202a to cool the gaseous refrigerant, and at least one may be provided to dissipate heat of the refrigerant in the heat exchange tube 202a. .

The wind pipe 203 is coupled to the turbo blower 201 , and discharges the compressed air generated by the turbo blower 201 to the outside, and the distal end is coupled to the windbreak port 104 and compressed through the windbreak port 104 . Air can be exhausted to the outside.

In addition, the windbreak valve 203a is provided in the windbreak pipe 203 to control the flow of the discharge air.

In detail, the wind valve 203a is normally opened to prevent the air from flowing to the windbreak port 104, and the air flows into the enclosure body 101 to be discharged through the heat exhaust hole 105, etc. can

On the other hand, when the turbo motor 201a is operated to generate discharge air, the windshield valve 203a may be blocked and the generated compressed air may flow to the windshield 104 and be discharged.

On the other hand, while the compressed air is discharged through the windshield 104, if the compressed air continuously generated by the turbo motor 201a is not smoothly discharged through the windshield 104, the compressed air continuously generated Due to this, a phenomenon in which compressed air is accumulated in the windbreak tube 203 may occur.

In this case, a surging phenomenon in which the compressed air flows backward in the direction of the turbo motor 201a may occur due to the accumulated pressure of the compressed air. For this reason, the efficiency of the turbomotor 201a may be impaired or the parts of the turbomotor 201a may be damaged due to the compressed air flowing backward.

In order to prevent such a surging phenomenon, when the compressed air flows backward due to the surging phenomenon, the windbreak valve 203a is opened to prevent the reverse flow of the compressed air from flowing to the turbo motor 203a.

In addition, a wind silencer 203b is coupled to the windbreak pipe 203 , so that vibration noise and the like generated from the windshield 203 , the windbreak valve 203a, and the like can be removed.

The receiver 204 is a refrigerant inflow from the heat exchanger 103 and is stored therein, and may include a receiver 204a, a filter drier 204b, and the like.

The gaseous refrigerant may be phase-changed into the liquid refrigerant while passing through the heat exchanger 103 , but the gaseous refrigerant that has not undergone phase change may remain even after passing through the heat exchanger 103 . Since the gaseous refrigerant that has not undergone phase change as described above cannot be supplied to the turbo motor 201a, the refrigerant that has passed through the heat exchanger 103 is stored in the transfusion container 204a and is separated into a gaseous refrigerant and a liquid refrigerant. can be

The infusion container 204a may have an inlet of the refrigerant above the outlet so that the refrigerant is separated into a gaseous refrigerant and a liquid refrigerant while the refrigerant flows in the gravity direction. That is, as the refrigerant introduced into the inlet falls downward in the direction of gravity, the liquid refrigerant having a relatively heavy mass may be accumulated in the lower portion of the transfusion container 204a, and the gaseous refrigerant having a relatively light mass may be stored in the transfusion container By remaining in the upper portion of the 204a, it can be separated into a gaseous refrigerant and a liquid refrigerant. In this way, the liquid refrigerant accumulated in the lower portion of the transfusion container 204a may be stored in the transfusion container 204a to be supplied to the turbomotor 201a.

The filter drier 204b filters impurities present in the refrigerant flowing out from the transfusion container 204a, and before the refrigerant is supplied to the pump 205, malfunctions in driving the turbo motor 201a, the pump 205, etc. Substances remaining in the refrigerant that can generate .

The refrigerant pump 205a transports the refrigerant so that the refrigerant is supplied to the turbo motor 201a.

The pump motor 205b provides power to the refrigerant pump 205a by coupling the refrigerant pump 205a and the rotating shaft.

While the refrigerant absorbs heat from the refrigerant pump (205a) and the pump motor (205b) to cool the refrigerant pump (205b) and the pump motor (205b), the temperature of the refrigerant may increase by about 1 degree to 2 degrees, the refrigerant Even if the pump 205 is cooled, it may be supplied to the turbomotor 201a through the pump 205 while maintaining a liquid state.

The sight glass 205d is provided so that the refrigerant flowing out from the refrigerant pipe 205c can be observed, and by visually observing the flow of the refrigerant flowing out from the refrigerant pipe 205c, the refrigerant flows smoothly to the turbomotor 201a. inflow can be observed.
