Description

Technical Field

[0001] The invention relates to the technical field of water vapor separators, in particular to a water vapor separator used for enameled wire processing. Background Art

[0002] During the wire enameling process, the water vapor generated needs to be effectively separated to ensure the stability of the processing environment and product quality. Currently, there are many types of water vapor separators on the market, such as filtration, centrifugal, condensation and adsorption water vapor separators, but they all have certain defects and limitations.

[0003] The filter-type water vapor separator separates water vapor from the gas through a filter screen or filter disc. Although this method has a simple structure, the filter material is difficult to effectively condense water vapor at room temperature, resulting in low separation efficiency; as the use time increases, the filter material is easily blocked by impurities and requires frequent maintenance and replacement.

[0004] The centrifugal water vapor separator separates water vapor from gas through the centrifugal force generated by high-speed rotation. This method is highly efficient, but requires high-speed rotation, so it consumes more power and has high operating costs. It also requires a high gas flow rate, and can only achieve the best separation effect within a certain flow rate range.

[0005] The condensation type water vapor separator separates water vapor by lowering the temperature to condense it into liquid water. This method is effective under certain conditions, but the condensation efficiency is greatly affected by the ambient temperature. It works better under low temperature conditions, but less effective under high temperature conditions and requires cooling devices and control systems, which increases the complexity and cost of the equipment. The adsorption type water vapor separator separates water vapor in the gas by adsorbing it with adsorbent materials. This method can achieve a higher separation effect, but the adsorbent material needs to be regenerated or replaced after adsorption saturation, which is complicated to operate.

[0006] In summary, the various existing water vapor separation technologies have their own advantages and disadvantages, but they all have certain limitations and it is difficult to maintain a stable separation effect in different usage environments.

[0007] In view of this, research and improvement are carried out on the existing problems, and a water vapor separator for enameled wire processing is provided to solve the current problems. The purpose is to solve the problems and improve the practical value through this technology. Summary of the invention

One end of the main shaft passes through the end cover and is fixedly connected to the output end of the driving motor. An eccentric wheel is arranged on the surface of the main shaft. The outer circumference center of the eccentric wheel deviates from the axis of the main shaft and the eccentric wheel is rotatably sleeved on the inner side of the rotor wheel. The rotor wheel is rotatably installed on the inner side of the compression separation cabin.

[0016] In a preferred example, the present invention can be further configured as follows: a gear ring seat is fixedly installed on the inner side of the rotor wheel, and the surface of the main shaft rod is fixedly sleeved with transmission teeth meshing with the gear ring seat, and the center of the transmission teeth is located on the axis line of the main shaft rod. The meshing movement of the transmission teeth on the surface of the gear ring seat during rotation is utilized to improve the movement stability of the rotor wheel.

[0017] In a preferred example, the present invention can be further configured as follows: the cross section of the rotor wheel is a Reuleaux triangle, and each triangle of the rotor wheel is provided with abutment bars for slidingly abutting against the inner wall of the compression separation cabin.

[0056] Specifically, the water-proof and breathable membrane 430 may be one or more combinations of Gore-Tex filter membrane, Millipore PTFE filter membrane and Whatman high-efficiency hydrophobic filter membrane, which can only allow gas to pass through but not liquid.

[0057] The working principle and use process of the present invention:

[0058] During operation of the water vapor separator, water vapor enters the compression separation cabin 110 through the water vapor inlet hole 111. Under the action of the driving motor 200, the main shaft 310 drives the rotor 300 to rotate, and the rotor wheel 320 starts to rotate. The rotation of the rotor wheel 320 gradually compresses the water vapor in the working chamber. During the compression process, the pressure and temperature of the water vapor increase, and the saturated vapor pressure increases. The compressed water vapor releases heat under the action of the cooling system, and the temperature drops rapidly, and begins to condense into liquid water. The cooling system includes a cooling liquid channel 113 and a liquid distribution ring cavity 123. External circulating coolant is introduced through the cooling liquid port 121 to achieve overall cooling of the sealed chamber inside the stator housing 100 and the compression separation cabin 110. On the rotor surface, the condensation veneer 322 (microporous membrane structure or hydrophilic coating structure) further promotes the condensation of water vapor and improves the condensation efficiency.

[0059] When the water vapor is compressed and passes through the exhaust hole on the surface of the compression separation cabin 110, it enters the interior of the filter air valve 400. The water-proof and breathable membrane 430 (hydrophobic filter membrane, PTFE filter membrane or microporous filter material) only allows gas to pass through and prevents liquid water from passing through, ensuring that the gas is discharged and the water remains in the compression separation cabin 110.

[0060] Afterwards, as the rotor wheel 320 rotates, the water is pushed through the lowest end of the water compression separation cabin 110 and flows to the other side of the compression separation cabin 110 until it is discharged through the water discharge hole 112, completing a water vapor separation, and forming a continuous water vapor separation operation under the continuous rotation of the rotor.

[0061] The principle of pressurization promoting water vapor condensation

[0062] Gas Saturated Vapor Pressure: Saturated vapor pressure refers to the pressure of a gas when liquid and gas are in equilibrium at a specific temperature. The higher the temperature, the higher the saturated vapor pressure. When a gas is pressurized, its saturated vapor pressure also increases.

[0063] Dew point temperature: The dew point temperature is the temperature at which water vapor in a gas begins to condense into liquid water. When the pressure of a gas increases, the dew point temperature rises accordingly. Under pressurized conditions, water vapor in a gas is more likely to reach saturation, that is, reach saturated vapor pressure, and thus more likely to condense into liquid water.

[0064] Condensation process: After pressurization, the water vapor content in the gas remains unchanged, but due to the increase in pressure, its saturated vapor pressure increases, and the dew point temperature at which the gas reaches a saturated state increases. When the gas pressure increases to a certain level, water vapor will condense more easily even if the temperature of the gas does not drop significantly.

[0065] Advantages in practical applications

[0066] Improve separation efficiency: Under pressurized conditions, water vapor in the gas condenses more easily and can be separated from the gas more efficiently. This improves the efficiency of the water vapor separator.

[0067] Reduced cooling requirements: At normal pressure, the gas needs to be cooled to a lower temperature to condense the water vapor. By pressurizing, condensation can be achieved at a higher temperature, reducing the need for cooling systems.

[0068] Energy saving effect: Condensation of water vapor by pressurization can reduce energy consumption because there is no need to cool the gas to extremely low temperatures.
