Description

Mechanical Vapor Recompression System with heat pipe combined cooling module}

The present invention relates to a mechanical vapor recompression device equipped with a heat pipe-coupled cooling module, and more specifically, to a heat pipe-coupled cooling module that can effectively cool the heat generated from the motor by the heat pipe-coupled cooling module. It relates to a mechanical vapor recompression device equipped with this.

Compressors generally developed in the field of vapor compression are developed using a refrigerant system, and may include refrigerant gas that is compressed by a refrigerant compressor and sent to a condenser. In a condenser, refrigerant gas exchanges heat with another fluid, such as air or water, and is condensed into a liquid. The liquid refrigerant discharged from the condenser passes through an expansion device and is sent to the evaporator. In the evaporator, the liquid refrigerant exchanges heat with another fluid, such as air or water, and is evaporated into gas. The refrigerant gas can return from the evaporator to the compressor and the cycle repeats.

On the other hand, in the case of water vapor rather than a refrigerant, a mechanical compressor is used to facilitate the use of water vapor as a heat source. When steam is adiabatically compressed, the temperature and pressure of the steam increase, and the amount of heat per unit volume of the steam increases. Because of this, more heat can be supplied when compressed steam is used as a heat source.

The Mechanical Vapor Recompression System (MVR) is produced by sucking and compressing the self-evaporation vapor of low-temperature waste heat generated in the product production process or the evaporation vapor of the heat medium through indirect heat exchange using a motor or turbine-driven compressor. This is a technology that reuses it as a heating heat source in the process. These MVRs are used in environmental industries such as distilled water production, desalination, and wastewater evaporation.

In particular, MVR compresses and uses water vapor evaporated from wastewater, and the condensed water is used to concentrate wastewater, so it can reduce evaporation energy by more than 90% compared to a general heat exchanger.

Meanwhile, compressors can be classified into a positive displacement type, which compresses while gradually reducing the volume, and a centrifugal type, which uses centrifugal force generated by an impeller rotating at high speed.

The positive displacement type is further classified into a rotary type and a reciprocating type. It is suitable for high compression ratios and is widely used to compress refrigerant gas. Initially, the positive displacement type was applied to waste water vapor, but it was properly adapted to changes in the moisture evaporation amount of waste water. If operation control is not accompanied, excessive vibration and noise are generated, so centrifugal type is preferred recently.

Centrifugal compressors are widely used as water vapor compressors, using a blower system with 8 to 24 blades bent backwards on a rotating impeller. They produce less noise and are more efficient than positive displacement compressors, and can withstand high-speed rotation well.

The centrifugal type can be controlled according to the moisture evaporation amount of wastewater by adjusting the rotation speed of the impeller rotating at high speed by an inverter, and has the advantages of good compression efficiency, good load characteristics, and low vibration and noise. However, there are problems such as overheating of the shaft due to high-temperature steam, lubrication/cooling by lubricating oil bearings, and additional facilities such as a lubricant cooling unit must be installed.

Accordingly, a high temperature load is formed due to the injection of wet steam, which adversely affects the normal operation of the centrifugal steam recompressor, causing abnormal operation, making it difficult to operate the normal steam recompression system.

An example of a technology to solve the above problem is disclosed in Document 1 below.

Patent Document 1 includes a hybrid turbo blower used in an MVR system, wherein the turbo blower includes a housing fixed to a support, a stator installed inside the housing and rotating a shaft inserted inside the stator by an applied power, and a stator inserted inside the stator. a shaft that rotates, a journal installed on both ends of the shaft and on which dynamic pressure air bearings are installed, a thrust formed on one side of the journal and on which a static pressure air bearing is installed, a disk pad on one side of the thrust and on which an impeller is mounted, and the disk An impeller is installed on the pad and rotates according to the operation of the stator to compress steam, and a casing is installed on the impeller side to intake and exhaust air, where the casing is an intake port for intake of steam, and a stator flowing in from the intake port. A hybrid turbo blower used in an MVR system is disclosed, which includes a vortex chamber in which steam is compressed and transported as the impeller rotates, and an exhaust port that moves along the vortex chamber and exhausts the compressed vapor.

However, the conventional technology as described above is an air-cooled air circulation system, which uses the rotational force of the impeller to bring in external air and supply it to the motor. At this time, the heat of the motor is discharged to the outside along with the air, thereby causing damage to the bearing. There is a problem that thermal imbalance occurs, which shortens the lifespan.

In addition, the conventional technology has a structure in which heat generated from copper loss and iron loss is conducted to the housing of the motor through the stator and dissipates heat. The temperature rise of the winding due to copper loss generated by the resistance of the winding (coil) causes the resistance to increase. The higher the current, the higher it occurs. As the temperature rises, the resistance of the winding increases and copper loss increases. As a result, the temperature rises further, reducing the efficiency of the MVR system and shortening its lifespan.

Hereinafter, the most preferred embodiments of the present invention will be described in detail in order to enable those skilled in the art to easily practice the present invention.

As shown in Figures 1 to 4, the mechanical vapor recompression device equipped with a heat pipe-coupled cooling module according to the present invention includes a housing 100 in which a motor 200 having a rotating shaft 210 is installed, It includes an impeller 300 that is coupled to one side of the rotating shaft 210 and compresses air through rotation, and a volute 400 that guides the movement of air compressed by the impeller 300.

In addition, the present invention is formed inside the housing 100, and is coupled to the shielding chamber 110, which is filled with refrigerant, and the upper part of the housing 100 to remove heat generated from the motor 200. It further includes a cooling module 500 for cooling.

As shown in Figures 2 and 3, the housing 100 is a hollow structure with a cylindrical interior, and a motor 200 including a rotating shaft 210, a rotor 220, and a stator 230 therein. is installed.

A cooling fan 600 is coupled to the other end of the rotation shaft 210.

And, a cap 120 to cover the cooling fan 600 is coupled to the other side of the housing 100.

The cooling fan 600 is disposed on the outside of the housing 100 and is coupled to the other end of the rotation shaft 210. In this case, the cooling fan 600 may be protected by the cap 120.

In particular, air flowing by driving the cooling fan 600 is supplied to the heat dissipation fin 530 of the cooling module 500 for forced cooling, thereby improving the cooling efficiency of the heat dissipation fin 530.

Meanwhile, the housing 100 is formed with a compressed air inlet 130 through which compressed air is injected to cool the bearing 700 and a compressed air outlet 140 through which compressed air is discharged.

In addition, a bearing cooling passage 150 is formed in the housing 100, which is separate from the shielding room 110 and communicates with the compressed air inlet 130 and the compressed air outlet 140, where cooling is performed by compressed air.

The bearings 700 are coupled to both outer peripheral surfaces of the rotating shaft 210, respectively. The bearing 700 contacts the rotating shaft 210 to fix the rotating shaft 210 in a predetermined position and serves to rotate the rotating shaft 210 while supporting the load applied to the rotating shaft 210.

To elaborate, the bearing 700 includes a hydrostatic bearing 710 coupled to one side of the rotating shaft 210, and a dynamic bearing 720 coupled to one side and the other side of the rotating shaft 210. The hydrostatic bearing 710 is an air bearing that secures space through external fluid pressure and maintains the gap even without being driven. In addition, the dynamic pressure bearing 720 maintains the gap by the pressure of the airfoil generated by its own rotation without external pressure supply.

In particular, compressed air is injected into the static pressure bearing 710, but compressed air is not injected into the dynamic pressure bearing 720, so cooling is not achieved. Therefore, the bearing must be cooled by injecting compressed high-pressure air from the outside of the bearing.

Accordingly, the heat generated by the dynamic bearing 720 can be cooled by injecting compressed air through the compressed air inlet 130 of the housing 100 and discharging the compressed air through the compressed air outlet 140.

In addition, a method may be applied in which the dynamic pressure bearing 720 and the static pressure bearing 710 are arranged adjacent to each other so that the heat generated in the dynamic pressure bearing 720 is cooled by supplying compressed air to the static pressure bearing 710.

Meanwhile, in order to construct the shielding room 110, the stator 230 of the motor 200 must be blocked from the outside, and in particular, unlike a general motor in which the exterior of the stator is fixed to the housing, the exterior of the stator is separated from the stator. Accordingly, it must be constructed with a separate structure to secure the stator.

As shown in FIGS. 3 and 5 to 7, the shielding chamber 110 may be formed by a shielding means 800 inserted through the rotor 220 of the motor 200.

Accordingly, the shielding means 800 includes a fixing tube 810, a fixing ring 820, and a pair of shielding flanges 830.

The fixing tube 810 has a cylindrical shape, and a plurality of slits 811 are formed along the circumferential direction on the outer peripheral surface. The stator 230 of the motor 200 is inserted into the outer peripheral surface of the fixing tube 810. The fixing tube 810 has a certain air gap with the rotor 220 to prevent interference with the rotor 220.

The fixing tube 810 does not shake at both ends of the stator 230, and the rest of the stator 230 does not form slits except for the slit 8110 where the stator 230 is coupled so that it is fixed in a certain position. A fixing ring 820 is inserted into a portion of the fixing tube 810 where a slit is not formed.

The fixing ring 820 is inserted into one side of the fixing tube 810 to fix the stator 230.

The shielding flange 830 is coupled to both ends of the fixing tube 810 to shield both ends of the stator 230. The shielding flange 830 is fixed to the end of the fixing tube 810 by welding or the like.

The shielding means 800 configured in this way maintains the gap between the stator 230 and the rotor 220, and at the same time, a fixing tube 810 is installed inside the stator 230 to shield the inner diameter of the stator 230. Insert. At this time, the slot of the stator 230 is inserted into the slit 811 of the fixing tube 810 and fixed.

Next, the fixing ring 820 is inserted into the portion of the fixing tube 810 where the slit is not formed to prevent the stator 230 from moving.

Then, shielding flanges 830 are coupled to both ends of the fixing tube 810 to shield the outside of the stator 230.

The outer diameter of the stator 230 is shielded by the housing 100.

As such, the present invention has the advantage of simplifying the formation of the shielding chamber 110 and increasing the shielding effect by forming the shielding chamber 110 in which the refrigerant is charged by the shielding means 800. In addition, the coil and stator 230 are immersed in a refrigerant and the heat generated from the coil and stator 230 is directly conducted to the refrigerant for cooling, thereby significantly improving heat dissipation efficiency.

As shown in Figures 2 and 3, the motor 200 includes a rotation shaft 210, a rotor 220, and a stator 230.

One side of the rotation shaft 210 may extend into the volute 400, and the other side may extend into the cap 120.

Additionally, bearings 700 are coupled to both sides of the rotating shaft 210, respectively. Additionally, an impeller 300 is coupled to one end of the rotating shaft 210, and a cooling fan 600 is coupled to the other end.

The rotor 220 may be disposed on the outer peripheral surface of the rotation shaft 210 and may rotate together with the rotation shaft 210. The stator 230 may be disposed inside the housing 100 to surround the outer circumference of the rotor 220. To elaborate, the rotor 220 functions as a rotor that rotates around the rotation shaft 210, and the stator 230 functions as a stator in which a coil is wound so that current flows and generates magnetic force to rotate the rotor. do.

The impeller 300 is coupled to one end of the rotating shaft 210 and serves to compress air through rotation. Accordingly, the air sucked in due to the rotation of the impeller 300 is discharged through the volute 400.

With this structure, when the rotor 220 of the motor 200 rotates and the impeller 300 rotates at the same time, air flows in and passes through the impeller 300, increasing the pressure, and flowing outward along the volute 400. It is discharged. Additionally, as the rotor 220 rotates, the cooling fan 600 rotates to cool the heat dissipation fin 530 of the cooling module 500.

As shown in Figures 1 and 2, the volute 400 is formed with an inlet through which external air flows in and an outlet through which air is discharged, and is coupled to the housing 100 using bolts or screws.

An impeller 300 that compresses the introduced air is rotatably disposed inside the volute 400, and the rotation of the impeller 300 is achieved by driving the motor 200. The air compressed by the impeller 300 is discharged through the discharge port.

As shown in FIGS. 2 and 8 , the cooling module 500 is coupled to the upper part of the housing 100 and includes a cooling channel 510, a heat pipe 520, and a heat dissipation fin 530.

The cooling channel 510 has a structure in which square-shaped blocks 511 are formed at the top and bottom, and a plurality of refrigerant flow pipes 512 are connected between the blocks 511.

Meanwhile, as shown in FIG. 9, the cooling channel 510 may be configured in the form of a square enclosure.

This cooling channel 510 has an area where the refrigerant that has received heat from the motor 200 evaporates and rises to export heat to the heat dissipation fin 520, and the cooled refrigerant descends by gravity.

The heat pipe 520 is roughly shaped like a 'U', and one end is connected to the cooling channel 510 to absorb heat generated by the motor 200 and transfer it to the heat dissipation fin 530.

The heat pipe 520 serves as a medium to absorb heat generated by the motor 200 and quickly transfer it to the low temperature part. Therefore, it is preferable that the inside of the heat pipe 520 is filled with a refrigerant with a low boiling point.

The refrigerant is preferably made of a fluid that evaporates below approximately 70°C. Examples of the refrigerant include water, acetone, methanol, ethanol, freon, and ammonia, but are not limited thereto. The refrigerant is effective in dissipating heat when used alone, but if the refrigerant is harmful to coils, stators, etc., a mixture of insulating oil and refrigerant can be used.

A plurality of heat dissipation fins 530 are installed on the heat pipe 520 and emit heat absorbed through the heat pipe 520.

According to the cooling module 500 configured as described above, when the heat generated by the motor 200 is transferred to the heat pipe 520 through the cooling channel 510, the refrigerant charged inside the heat pipe 520 is converted into heat. It vaporizes. The vaporized refrigerant in the heat pipe 520 transfers heat to the heat dissipation fin 530, releases heat through the heat dissipation fin 530, and is liquefied. The liquefied refrigerant descends again and moves to the shielding room 110 of the housing 100, and this process is repeated to cool the motor 200.

In this way, the present invention cools overheating of the motor 200 by the cooling module 500 including the cooling channel 510, the heat pipe 520, and the heat dissipation fin 530, while preventing steam from penetrating into the motor 200. This prevents the vapor from being recompressed stably.

As shown in FIG. 10, a cooling line 910 may be installed on the outside of the housing 100, with one end connected to the cooling module 500 and the other end connected to the lower part of the motor 200.

Therefore, the motor 200 can be cooled by allowing the cooled gas passing through the outside of the housing 100 to flow to the lower part of the motor 200 through the cooling line 910.

As shown in FIGS. 11 to 13, on the outside of the housing 100 is an air duct with one end connected to the cap 120 and the other end extending to accommodate the heat dissipation fin 530 of the cooling module 500 therein. (920) can be installed.

To elaborate, one end of the air duct 920 communicates with the upper part of the cap 120, and the other end accommodates the heat dissipation fin 530 of the cooling module 500, but has a structure that is open toward the outside.

Therefore, the air duct 920 serves to guide the air flowing by the driving of the cooling fan 600 to the heat dissipation fin 530 of the cooling module 500, thereby cooling the heat dissipation fin 530.

The present invention has been described with a focus on preferred embodiments with reference to the accompanying drawings, but it is clear to those skilled in the art that various modifications can be made without departing from the scope of the present invention from this description. Accordingly, the scope of the present invention should be construed by the appended claims to include examples of many such modifications.
