Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas drying technology, and more specifically, to a gas drying device and a vehicle suspension air supply system. Background Technology
[0002] In the field of gas drying, existing technologies often use molecular sieves as desiccants to adsorb moisture in gases, thereby achieving the purpose of drying the gases. Specifically, the gas is compressed by a compressor and then enters a drying cylinder containing a molecular sieve. When the high-pressure gas flows through the molecular sieve, the molecular sieve comes into contact with the moisture in the gas, and the moisture is adsorbed by the molecular sieve. However, as the amount of moisture adsorbed in the molecular sieve increases, the molecular sieve gradually becomes saturated, and its ability to absorb moisture decreases until it can no longer absorb moisture, resulting in a decrease in the gas drying effect.
[0003] In existing technologies, to improve the gas drying effect, backflushing with drying gas is usually used, which uses the reverse airflow to remove the moisture adsorbed inside the molecular sieve. However, using only the reverse airflow for backflushing can only remove a limited amount of moisture, resulting in a low molecular sieve regeneration rate. In current technologies, high-temperature reverse airflow is used for backflushing to increase the temperature of the molecular sieve itself, thereby improving the regeneration rate. However, the contact time between the high-temperature gas and the molecular sieve is short, which can easily cause uneven temperature inside the molecular sieve, and the molecular sieve heats up slowly, which is not conducive to the rapid precipitation of moisture inside the molecular sieve, resulting in a low molecular sieve regeneration efficiency.
[0004] In summary, how to solve the problem of low regeneration rate and efficiency of molecular sieves is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] The core of this invention is to provide a gas drying device. By directly installing a heating component inside the cylinder to directly heat the molecular sieve, and monitoring the temperature with a temperature sensor to adjust the power of the heating component in real time, the device achieves closed-loop temperature control of the molecular sieve, enabling it to efficiently precipitate moisture at the set temperature, thereby improving the regeneration rate and efficiency of the molecular sieve.
[0039] Another core aspect of this utility model is to provide a vehicle suspension air supply system that includes the aforementioned gas drying device, which has the same technical features and can solve the same technical problems.
[0040] Please refer to Figure 1 and Figure 2 A gas drying apparatus, comprising:
[0041] The cylinder 3 has molecular sieves 6 filling its internal flow channels;
[0042] Heating component 7 is disposed inside cylinder 3 and is used to contact and heat molecular sieve 6;
[0043] A temperature sensor is installed inside the cylinder 3, and its output is electrically connected to the control unit of the heating component 7.
[0044] like Figure 1 and Figure 2 As shown, the heating component 7 is directly built into the cylinder 3, so that the heating component 7 is in direct contact with the molecular sieve 6 and can directly exchange heat with the molecular sieve 6, thereby enabling the molecular sieve 6 to be heated quickly and evenly, and thus the temperature of the molecular sieve 6 can be rapidly increased to a temperature range that is conducive to the precipitation of water inside the molecular sieve 6. When the drying airflow passes through the molecular sieve in the reverse direction, it can carry away the precipitated water, thereby realizing the regeneration of the analytical sieve.
[0045] Meanwhile, as the molecular sieve 6 is heated by the heating component 7, the rate of moisture extraction inside it increases, thus increasing the regeneration rate of the molecular sieve 6. Moreover, the high temperature helps to increase the rate of moisture extraction inside the molecular sieve 6, thus increasing the regeneration efficiency of the molecular sieve 6.
[0046] Moreover, the cylinder 3 integrates a temperature sensor to monitor the temperature inside the cylinder 3 in real time, and transmits the monitoring results to the control unit of the heating component 7 through a copper busbar to realize closed-loop control of the heating component 7. This ensures that the molecular sieve 6 inside the cylinder 3 is always in the temperature range where water is efficiently extracted, thereby saving equipment energy consumption while ensuring the regeneration rate and regeneration efficiency of the analytical sieve 6.
[0047] In some embodiments, both ends of the cylinder 3 are provided with end caps 4 for sealing, and the end caps 4 are provided with air pipe connectors 2 through them.
[0048] At least one set of end caps 4 are externally fixed with connectors 1, which are electrically connected to the heating assembly 7 via wires.
[0049] like Figure 1 As shown, end caps 4 are provided at both ends of the cylinder 3 to seal the cylinder 3. Both end caps 4 are provided with air pipe connectors 2 to facilitate the connection of the air inlet pipe and the air outlet pipe. Meanwhile, a connector 1 is fixedly installed on the outside of one end cap 4. The connector 1 is connected to the heating component 7 through a copper plate and is powered by an external wire. At the same time, the connector 1 is connected to the temperature sensor through a copper busbar to realize signal transmission.
[0050] In some embodiments, both ends of the internal flow channel of the cylinder 3 are provided with filter components 8 and support components 9 for supporting the filter components 8, and the molecular sieve 6 is disposed in the area enclosed by the two sets of filter components 8 and the inner wall of the cylinder 3.
[0051] At least one set of support components 9 is provided with a compression spring 5 between the end cap 4 at the corresponding end of the cylinder 3.
[0052] like Figure 2 As shown, filter components 8 are respectively set at both ends of the cylinder 3 to filter the airflow passing through the cylinder 3 twice. One is to prevent external impurities from entering the molecular sieve 6, and the other is to prevent the molecular sieve 6 from flowing out of the cylinder 3 with the airflow. The filter component 8 is preferably a filter pad, which has a small thickness and can meet the filtration requirements.
[0053] Meanwhile, in order to prevent the filter component 8 from wrinkling during use and causing some airflow to bypass the filter component 8, a support component 9 is added to support the filter component 8, keep it flat, and avoid filter gaps.
[0054] Meanwhile, a compression spring 5 is added to one end of the cylinder 3. The two ends of the compression spring 5 abut against the inner wall of the end cap 4 and the support component 9 at the corresponding ends, so that the combination of the support component 9 and the filter component 8 can press the molecular sieve 6 tightly and prevent it from flowing in the cylinder 3 during operation.
[0055] In some embodiments, the heating component 7 is a cylindrical structure, and both ends of the heating component 7 are provided with sealing caps, and the sealing caps are provided with air pipe connectors 2.
[0056] Molecular sieve 6 is located within the area enclosed by heating component 7 and sealing cap.
[0057] like Figure 2 As shown, the heating component 7 is configured as a cylindrical structure with sealing caps at both ends, which helps to reduce internal heat loss, further save equipment energy consumption, and helps to quickly raise the temperature of the molecular sieve 6, thereby improving the regeneration efficiency of the molecular sieve 6.
[0058] In some embodiments, both ends of the heating assembly 7 are provided with a filter assembly 8 and a support assembly 9 for supporting the filter assembly 8, and the molecular sieve 6 is disposed in the area enclosed by the two sets of filter assemblies 8 and the inner wall of the heating assembly 7.
[0059] At least one set of support components 9 is provided with a compression spring 5 between the sealing cap at the corresponding end of the heating component 7 and the support component 9.
[0060] Filter components 8 are installed at both ends inside the heating component 7 to filter the airflow passing through the heating component 7 twice. One is to prevent external impurities from entering the molecular sieve 6, and the other is to prevent the molecular sieve 6 from flowing out of the heating component 7 with the airflow. The filter component 8 is preferably a filter pad with a small thickness that can meet the filtration requirements. At the same time, a support component 9 is added to support the filter component 8 to keep it flat and avoid filtration gaps.
[0061] A compression spring 5 is added, with its two ends abutting against the inner wall of the sealing cap and the support component 9 at the corresponding ends, so that the combination of the support component 9 and the filter component 8 can press the molecular sieve 6 tightly, preventing it from flowing in the heating component 7 during operation.
[0062] In some embodiments, the heating component 7 is a cylindrical structure, and the inner wall and / or outer wall of the heating component 7 are provided with a plurality of sets of heat-conducting fins 71 extending radially, and the molecular sieve 6 is disposed in the gap between two adjacent sets of heat-conducting fins 71.
[0063] like Figure 3 As shown, the heating component 7 is a cylindrical structure with several sets of heat-conducting fins 71 extending radially on the inner and / or outer walls to facilitate rapid heat conduction. This helps to heat the molecular sieve 6 at different locations, thereby ensuring a uniform temperature of the molecular sieve 6 in different areas and preventing heat concentration.
[0064] In some embodiments, the surface of the heat-conducting fin 71 is provided with a plurality of through holes 72, the diameter of the through holes 72 being not less than the monomer diameter of the molecular sieve 6.
[0065] like Figure 4As shown, several sets of through holes 72 are provided on the surface of the heat-conducting fins 71, and the diameter of the through holes 72 is larger than the monomer diameter of the molecular sieve 6. Therefore, the molecular sieve 6 can flow in the through holes 72 during the filling stage, avoiding voids inside the cylinder 3, thereby improving the drying efficiency of the drying device for the gas.
[0066] In some embodiments, heat-conducting fins 71 are disposed on the inner wall of the heating assembly 7, and the lengths of adjacent sets of heat-conducting fins 71 in the radial direction of the heating assembly 7 are not equal.
[0067] like Figure 3 As shown, the heat-conducting fins 71 on the inner wall of the heating component 7 have different lengths, including long fins and short fins. The long and short fins are arranged in a cross pattern, which ensures that the difference between the fin density at the center of the cylinder and the fin density at the edge of the cylinder is small. This helps to reduce the problem of heat concentration inside the cylinder, so that the heat inside the molecular sieve 6 is evenly distributed, thereby improving the overall water separation efficiency.
[0068] In some embodiments, the temperature sensor is disposed inside the heating assembly 7, and the temperature sensor is electrically connected to the connector 1 via a copper busbar.
[0069] Integrating the temperature sensor directly into the heating component 7 facilitates its installation and placement. Furthermore, the copper busbar electrically connects the temperature sensor to the connector 1, which helps ensure stable signal transmission.
[0070] In some embodiments, the heating component 7 is a cylindrical or sheet-like structure, and a thick film heating layer is provided on the surface of the heating component 7.
[0071] The heating component 7 can be selected as a cylindrical structure, and a thick film heating layer is provided on the outer periphery of the cylinder. The cylinder is heated instantly by the thick film heating method, and the molecular sieve 6 inside is heated after the heat is conducted through the cylinder.
[0072] In some embodiments, the heating component 7 adopts a sheet-like structure and has a thick film heating layer on its surface, using thick film heating to directly heat the molecular sieve 6 it contacts.
[0073] Among them, the thick film heating method has the advantage of resisting high temperature performance degradation compared with other resistance wire heating methods, which can ensure the temperature rise rate of the heating component 7 under high temperature conditions and ensure that the moisture in the molecular sieve 6 can be quickly released.
[0074] In addition to the gas drying apparatus disclosed in the above embodiments, the present invention also provides a vehicle suspension air supply system including the above-mentioned gas drying apparatus. The structure of other parts of the vehicle suspension air supply system is described in the prior art and will not be repeated here.

[0076] The gas drying device provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of this utility model.
