Description

Technical Field

[0001] This invention relates to the field of dehumidifier technology, and in particular to a rotary humidity removal device. Background Technology

[0002] In the field of rotary dehumidifiers, when gas containing a certain humidity level is dehumidified by a rotary dehumidifier, it becomes ultra-low dew point gas. This ultra-low dew point gas is then introduced into the operating environment (which requires an ultra-low dew point of -40℃DP or lower) through industrial pipelines to achieve this ultra-low dew point environment. However, often in industrial ventilation duct connections, vibration, aging, poor welding, and other factors cause changes in the dew point of the ultra-low dew point gas within the pipeline, resulting in the failure to meet the dew point requirements of the operating environment and causing problems with the entire rotary dehumidifier system. This new type of pipeline can effectively solve problems such as pipeline failure due to poor manufacturing or prolonged use, ensuring long-term, stable, and effective protection against ultra-low dew point gas. Summary of the Invention

The heater is also connected to the first filter, the cooling coil is also connected to the inlet of the main processing fan, the outlet of the main processing fan is connected to the second filter, and the novel ventilation duct is also connected to the pipeline between the main processing fan and the second filter.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1, such as Figure 1 As shown, a rotary humidity removal device includes a regeneration fan 1, an adsorption dehumidification rotor 2, a heater 3, a first filter 4, a second filter 5, a main processing fan 6, a cooling coil 7, and a novel ventilation duct 8. The inlet of the regeneration fan 1 is connected to the adsorption dehumidification rotor 2. The adsorption dehumidification rotor 2 is also connected to the heater 3, the cooling coil 7, and the novel ventilation duct 8. The heater 3 is also connected to the first filter 4. The cooling coil 7 is also connected to the inlet of the main processing fan 6. The outlet of the main processing fan 6 is connected to the second filter 5. The novel ventilation duct 8 is also connected to the pipeline between the main processing fan 6 and the second filter 5. The outlet of the regeneration fan 1 is connected to the heater 3.

[0019] The new ventilation duct 8 consists of a main duct 81, a wrapping duct 82, and an output duct 83. The wrapping duct 82 is wrapped around the main duct 81. The main duct 81 is connected to the wrapping duct 82 through the end of the duct. The output duct 83 is connected to the wrapping duct 82.

[0020] Both the main duct 81 and the outer sheath duct 82 are independent ventilation structures. The output duct 83 is equipped with a damper for controlling the flow rate of the protective gas. The output duct 83 is installed at the end furthest from the point where the main duct 81 connects to the outer sheath duct 82. The output duct 83 is also connected to the fan intake.

[0021] This device is designed with a dual-layer air duct system. The main internal duct introduces ultra-low dew point air from the rotary dehumidifier into the operating environment, while the auxiliary external duct draws a small amount of ultra-low dew point air from the main duct through the negative pressure of the main fan of the rotary dehumidifier, ensuring an ultra-low dew point air flow in the auxiliary duct. This ultra-low dew point environment in the auxiliary duct protects the main duct, guaranteeing a stable and reliable ultra-low dew point for the air in the main duct. Other components of the auxiliary duct are connected to the rotary dehumidifier's treatment inlet for recirculation.

[0022] The working principle is as follows: The ultra-low dew point gas, after being treated by the adsorption-type rotary dehumidifier, is piped to the ultra-low dew point usage area. This ultra-low dew point ventilation duct is designed for this area, and its design principle is shown in the schematic diagram on the right (the specific design can be customized according to the project requirements). This type of ultra-low dew point ventilation duct adopts a double-layer design structure. Figure 2 In the diagram, the main duct 81 is defined as the Zone I duct, the wrapping duct 82 is defined as the Zone II duct, and the output duct 83 is defined as the Zone III duct. The Zone II duct wraps around the Zone I duct. At the same time, the Zone I and Zone II ducts are independent ventilation structures. The Zone I duct is only connected to the Zone II duct through the end design of the duct, allowing a very small amount of ultra-low dew point gas from the Zone I main duct to flow into the Zone II duct. The Zone II duct is connected to the main fan F intake point 1 through the bypass duct of Zone III.

[0023] This double-layer enclosed design ensures that Zone II is also an ultra-low dew point area and a flowing gas area. Zone II will protect Zone I under various operating conditions, eliminating or significantly reducing the impact of deterioration in the dew point value of ultra-low dew point gas caused by leaks due to welding, glue cracking, etc., caused by long-term use. This reliably guarantees the ultra-low dew point value of the gas in Zone I pipelines and greatly extends the reliable service life of Zone I pipelines. A pressure difference will be formed between Zones I, II, and III, ensuring normal airflow, and the airflow magnitude will be regulated by the air valve in Zone III. The ultra-low dew point gas in Zone II (e.g., ultra-low dew point N2) will eventually flow into the main treatment fan inlet through the Zone III pipeline for recycling, preventing waste.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
