Description

Technical Field

[0001] The present invention relates to the technical field of air dryers, and in particular to an energy-saving air dryer. Background Art

[0002] Based on the ingenious combination of refrigeration technology and thermodynamics principles, a cold dryer utilizes the low-temperature environment generated by the refrigeration system to condense the moisture in the wet air into liquid and discharge it, thereby achieving the drying treatment of the air. In this process, an efficient heat exchanger plays a crucial role. It is responsible for transferring the cold quantity of the refrigerant to the wet air while ensuring the effective recovery and utilization of heat to achieve the purpose of energy conservation and emission reduction.

[0003] During the process of cooling the refrigerant gas in the existing cold dryer, the heat exchanger is a key component for heat transfer efficiency. However, the design of the existing heat exchanger often makes it difficult to maintain high-efficient heat transfer performance in a high-temperature environment. Especially under the conditions of high humidity and large temperature difference changes, the heat exchange efficiency is prone to decline. In a high-temperature environment, impurities and moisture in the air are easy to scale or accumulate on the surface of the heat exchanger, which not only affects the effective transfer of heat but also may lead to the performance decline of the heat exchanger, further reducing the heat transfer efficiency, resulting in high energy consumption and low heat transfer efficiency of the cold dryer.

[0030] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, the functions and arrangements of the elements discussed can be changed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0031] Embodiment: The technical solution of the present invention will be further elaborated in detail below in conjunction with the specification drawings and specific embodiments. Please refer to Figures 1 to 6 , an energy-saving air dryer provided by the present application. Please pay special attention to referring to Figure 1 , Figure 2 , Figure 4 and Figure 5, including a housing 1; a compressor 2 is installed on one side of the inner bottom of the housing 1, a liquid filling joint 6 is installed on the outer side of the compressor 2, a Hongyuan plate heat exchanger 3 is installed on one side of the inner wall of the housing 1 close to the compressor 2, the liquid filling joint 6 is used to convey high-pressure gas to the Hongyuan plate heat exchanger 3, and the Hongyuan plate heat exchanger 3 is used to cool the gas for the first time. A wind condenser 5 is installed on the inner top of the housing 1 close to the compressor 2, and the wind condenser 5 is used to further cool the gas and release heat. Pipelines 7 are installed between the compressor 2, the Hongyuan plate heat exchanger 3 and the wind condenser 5. A buffer mechanism 8 is installed on the pipeline 7 between the Hongyuan plate heat exchanger 3 and the wind condenser 5, and the buffer mechanism 8 is used to slow down the gas flow rate; The buffer mechanism 8 includes a connecting cylinder 801, a connecting frame 802, a connecting shaft 803, a wind blade 804 and a damping net 805. A connecting cylinder 801 is installed on the pipeline 7 between the Hongyuan plate heat exchanger 3 and the wind condenser 5. A connecting frame 802 is installed inside the connecting cylinder 801. A connecting shaft 803 is rotatably installed inside the connecting frame 802. A damping net 805 is installed on the outer side of one end of the connecting shaft 803, and a wind blade 804 is installed on the outer side of the connecting shaft 803 away from the damping net 805.

[0032] Specifically, the compressor 2 is used to compress the refrigerant into high-pressure gas. The high-pressure gas enters the Hongyuan plate heat exchanger 3 through the liquid filling joint 6. The Hongyuan plate heat exchanger 3 cools the refrigerant for the first time. The cooled refrigerant continues to be conveyed to the wind condenser 5 through the pipeline 7, further cooled and releases heat. The refrigerant that has been cooled twice returns to the compressor 2 through the pipeline 7 to complete one cycle. The buffer mechanism 8 is used to slow down the gas flow rate. The connecting cylinder 801, as the main part of the buffer mechanism 8, provides an installation space for the wind blade 804 and the damping net 805. The connecting frame 802 is responsible for supporting the connecting shaft 803 so that it can rotate freely under the push of the gas. The wind blade 804 is installed on the side of the connecting shaft 803 away from the damping net 805. When the gas passes through the connecting cylinder 801, it will push the wind blade 804 to rotate. This rotation can further slow down the gas flow rate. The damping net 805 is composed of a fine mesh structure. When the gas passes through, it will be blocked by the damping net 805, thereby further reducing the flow rate, so that the gas can gradually reduce the flow rate when passing through the buffer mechanism 8, thus optimizing the performance and efficiency of the entire system. Through the combination of the wind blade 804 and the damping net 805, the flow rate of the high-pressure gas in the pipeline 7 is effectively slowed down, which helps the gas to dissipate heat more fully between the Hongyuan plate heat exchanger 3 and the wind condenser 5.

[0033] Please refer specifically to Figure 1 , a boat-shaped switch 101 is installed on one side of the top of the housing 1, and a dew point display 102 is installed on the side of the housing 1 close to the boat-shaped switch 101.

[0034] Specifically, the boat-shaped switch 101 can realize the connection and disconnection of the circuit and control the switch of the electrical equipment. The dew point display 102 can directly display the humidity and temperature conditions in the measured gas on the screen, facilitating the user's observation and analysis. By adding an intelligent control function, the convenience and comfort of the user can be improved.

[0035] Please refer particularly to Figure 1 、 Figure 2 and Figure 3 , the compressor 2 is connected to the liquid filling joint 6 and the Hongyuan plate heat exchanger 3 through a set of pipelines 7. A protective sleeve 701 is sleeved on the pipeline 7 between the compressor 2 and the Hongyuan plate heat exchanger 3. The Hongyuan plate heat exchanger 3 is connected to the air condenser 5 through a set of pipelines 7. The air condenser 5 is connected to the compressor 2 through a set of pipelines 7. The Hongyuan plate heat exchanger 3 uses a flow channel formed by a series of corrugated plates to enable heat exchange between two fluids between the plates. The hot fluid transfers heat to the plates and then to the cold fluid through the plates, thereby realizing the transfer of heat. The air condenser 5 uses the forced convection air generated by the fan to accelerate the dissipation of heat. The refrigerant flows in the pipeline of the air condenser, while the air flows outside the pipeline, and takes away the heat of the refrigerant through heat exchange, causing it to evaporate into a gas.

[0036] Specifically, in order to compress the refrigerant into a high-pressure gas and transport and cool it, the compressor 2 compresses the refrigerant into a high-pressure gas and transports it to the Hongyuan plate heat exchanger 3 through the liquid filling joint 6 for the first cooling. The cooled refrigerant continues to be transported to the air condenser 5 through the pipeline 7. In the air condenser 5, the high-pressure gas further exchanges heat with the air for cooling and releases heat. The refrigerant that has been cooled twice returns to the compressor 2 through the pipeline 7 again, ready for the next round of compression and condensation cycle. The refrigerant continuously circulates between the compressor 2, the Hongyuan plate heat exchanger 3 and the air condenser 5, realizing the effective transfer of heat and the refrigeration effect. The protective sleeve 701 sleeved on the pipeline 7 mainly plays the roles of heat preservation, anti-corrosion and reduction of heat loss. It helps to maintain the temperature stability of the fluid in the pipeline 7, prevent temperature fluctuations caused by the external environment, and at the same time protect the pipeline 7 from physical damage and chemical corrosion.

[0037] Please refer particularly to Figure 1 and Figure 2 , a drainer 4 is installed on the side of the Hongyuan plate heat exchanger 3 close to the compressor 2. The drainer 4 is connected and installed to the Hongyuan plate heat exchanger 3 through a 90° female screw elbow. A drain pipe 401 is installed at the bottom end of the drainer 4, and the drainage end of the drain pipe 401 extends to the outside of the housing 1.

[0038] Specifically, in order to drain the liquid formed by water condensation in a timely manner, in the Hongyuan plate heat exchanger 3, condensate water is generated during the cooling process of the refrigerant. The main function of the drainer 4 is to collect and drain this condensate water to prevent it from accumulating inside the heat exchanger, which may affect the heat exchange efficiency or cause problems such as corrosion and blockage. By draining the condensate water in a timely manner, the drainer 4 helps to maintain the stable operation of the system and avoid performance degradation or failures caused by water accumulation. When humid air is introduced into the cold dryer and comes into contact with the low-temperature surface, the moisture condenses into a liquid and is discharged through the drainer 4. The drain pipe 401 guides the condensate water collected by the drainer 4 to the outside of the housing 1, ensuring that the condensate water does not accumulate inside the equipment or in the surrounding environment. By draining the condensate water in a timely manner, the drainer 4 helps to keep the inside of the Hongyuan plate heat exchanger 3 clean and dry, thereby improving the heat exchange efficiency and ensuring the refrigeration or heating performance of the system.

[0039] Please refer specifically to Figure 1 and Figure 6 , on the side of the pipeline 7 between the Hongyuan plate heat exchanger 3 and the air-cooled condenser 5 close to the Hongyuan plate heat exchanger 3, a bypass valve 702 is installed, and a dryer filter 706 is installed on the pipeline 7 between the Hongyuan plate heat exchanger 3 and the air-cooled condenser 5.

[0040] Specifically, in order to dry the refrigerant, when the refrigerant flow rate is too large or there is a blockage inside the Hongyuan plate heat exchanger 3, the bypass valve 702 can be manually opened to prevent the Hongyuan plate heat exchanger 3 from being overloaded or damaged. The main function of the dryer filter 706 is to remove moisture, acids, alkalis, metal particles and other impurities from the refrigerant to prevent these pollutants from damaging the system. The dryer filter 706 is usually filled with hygroscopic materials and filtering media, which are molecular sieves and filter meshes. These materials can adsorb and filter out the moisture and impurities in the refrigerant. When the refrigerant passes through the dryer filter 706, the moisture and impurities in it will be adsorbed or filtered out, thereby ensuring the clean circulation of the refrigerant in the system. By using the dryer filter 706, it helps to extend the service life of the compressor 2 and the Hongyuan plate heat exchanger 3. The combined use of the bypass valve 702 and the dryer filter 706 enhances the stability and reliability of the system under various working conditions, ensuring that the system can operate efficiently under different loads and environments.

[0041] Please refer specifically to Figure 1 , on the pipeline 7 between the dryer filter 706 and the bypass valve 702, a first fan temperature controller 703 is installed, and a second fan temperature controller 704 is installed on the side of the pipeline 7 close to the first fan temperature controller 703.

[0042] Specifically, in order to monitor the temperature of the refrigerant transported in pipeline 7, temperature sensors are usually installed inside the first fan temperature controller 703 and the second fan temperature controller 704 to measure the temperature of the refrigerant in pipeline 7 in real time. The first fan temperature controller 703 and the second fan temperature controller 704 are usually connected to the fan to automatically adjust the speed or start / stop of the fan according to the temperature change, which helps to maintain the temperature balance inside the system and prevent system failures caused by too high or too low temperature, thereby improving the overall performance and efficiency of the system.

[0043] Please refer specifically to Figure 1 and Figure 3 , a fresh air fan 501 is installed at the bottom of the air-cooled condenser 5. The fresh air fan 501 is used to help dissipate the excess heat on the air-cooled condenser 5. Inside the housing 1, a honeycomb grid 103 is arranged in an array near the top of the air-cooled condenser 5. The honeycomb grid 103 is used for the air-cooled condenser 5 to dissipate heat. The working principle of the fresh air fan 501 is based on the heat exchange principle, that is, using air flow to take away the heat on the condenser 5. The honeycomb grid 103 promotes the convective heat dissipation on the surface of the condenser by increasing the heat dissipation area and optimizing the air flow distribution, thereby improving the heat dissipation efficiency.

[0044] Specifically, to enhance the heat dissipation effect of the air-cooled condenser 5, the fresh air fan 501 helps to dissipate the excess heat on the air-cooled condenser 5 by introducing fresh air, which helps to reduce the temperature of the air-cooled condenser 5 and improve its heat dissipation efficiency, thereby ensuring the stable operation of the system. The honeycomb grid 103 improves the heat dissipation efficiency of the air-cooled condenser 5 by increasing the heat dissipation area, which helps to dissipate heat faster and reduce the temperature of the air-cooled condenser 5.

[0045] Please refer specifically to Figure 1 , a compressor temperature controller 705 is installed on the pipeline 7 between the air-cooled condenser 5 and the compressor 2. The compressor temperature controller 705 is used to monitor and control the temperature of the compressor 2.

[0046] Specifically, in order to monitor and control the temperature of the compressor 2 in real time and ensure the stable operation and high efficiency of the compressor 2, a temperature sensor is installed inside the compressor temperature controller 705 to monitor the temperature of the compressor 2 in real time. The compressor temperature controller 705 can monitor the temperature of the compressor 2 in real time and perform precise control according to the preset temperature range, which helps to ensure that the compressor 2 always operates within the optimal temperature range, thereby improving its working efficiency and stability. By monitoring and controlling the temperature in a timely manner, the compressor temperature controller 705 can effectively prevent the compressor 2 from failing due to overheating, which helps to extend the service life of the compressor 2.

[0047] Please refer specifically to Figure 4 and Figure 5, on the outer side of the end of the coupling shaft 803 far from the wind blade 804, multiple drying plates 901 are installed, and the drying plates 901 are evenly distributed in a circle on the outer side of the coupling shaft 803.

[0048] Please refer specifically to Figure 4 and Figure 5 , on the outer side of the coupling shaft 803 close to the drying plate 901, an inclined plate 9 is installed. The inclined plate 9 is inclined. The inclined plate 9 and the drying plate 901 are made of the same material and are both composed of drying materials.

[0049] Specifically, in order to perform a preliminary drying treatment on the refrigerant and improve the treatment effect of the later drying filter 706 on the refrigerant, the main function of the drying plate 901 is to absorb or remove moisture or water in the surrounding air. The coupling shaft 803 is a key component connecting components such as the wind blade 804 and the drying plate 901. It is responsible for transmitting the rotational power from the wind blade 804, enabling the inclined plate 9 and the drying plate 901 to rotate together with the wind blade 804. This rotational movement helps to increase the contact area and time between the inclined plate 9 and the drying plate 901 and the air, thereby improving the drying effect. At the same time, the rotation of the inclined plate 9 can promote heat dissipation of the gas. When the air flow passes through the drying plate 901, the drying plate 901 will absorb the moisture or water in the air flow. As the drying plate 901 rotates, its surface will continuously come into contact with new air flows, thereby continuously performing the drying operation, and further improving the treatment effect of the later drying filter 706 on the refrigerant.

[0050] Working principle: After the device is started, the compressor 2 starts to work. The compressor 2 compresses the refrigerant into high-pressure gas. The high-pressure gas enters the Hongyuan plate heat exchanger 3 through the liquid filling joint 6. The Hongyuan plate heat exchanger 3 uses a series of flow channels formed by corrugated plates to enable heat exchange between two fluids between the plates. The hot fluid transfers heat to the plates and then to the cold fluid through the plates, thereby achieving heat transfer. The refrigerant is cooled for the first time here. The cooled refrigerant continues to be transported to the air condenser 5 through the pipeline 7. The air condenser 5 uses the forced convection air generated by the fan to accelerate heat dissipation. The refrigerant flows in the pipeline of the air condenser 5, while the air flows outside the pipeline. The heat of the refrigerant is taken away through heat exchange, causing it to evaporate into gas, further cooling the refrigerant and releasing heat. The fresh air blower 501 on the air condenser 5 introduces fresh air to help dissipate the excess heat on the air condenser 5 and maintain the stability of the system. The refrigerant that has been cooled twice returns to the compressor 2 through the pipeline 7 to complete a cycle. During this process, the air with high humidity is introduced into the device, comes into contact with the low-temperature surface, and the moisture condenses into liquid and is discharged through the drainer 4.

[0051] The above-described embodiments of the specific implementation manner have been described, but this embodiment is not limited to the above specific implementation manner. The above specific implementation manner is merely illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
