Abstract
Description
Technical Field
[0001] This utility model relates to the field of engine technology, and in particular to an engine intake centrifugal adsorption synergistic dehumidification device. Background Technology
[0002] During engine operation, excessive humidity reduces air density, leading to a decrease in oxygen content. This affects the fuel-air mixture, causing incomplete combustion and reduced power. Furthermore, moisture can accelerate corrosion and wear of components such as cylinders and piston rings. Currently, engines typically use air filters to dehumidify the intake air. However, air filters have relatively poor dehumidification efficiency, and excessive humidity can cause the filter element to become damp, losing its dehumidification effect and compromising air filtration. Utility Model Content
[0003] To address the aforementioned issues, this invention provides an engine intake centrifugal adsorption synergistic dehumidification device, which can effectively reduce the humidity of engine intake air and improve combustion stability.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An engine intake centrifugal adsorption synergistic dehumidification device includes a housing, an impeller, and a moisture absorption cylinder. An intake pipe and an exhaust pipe are respectively provided at both ends of the housing. A fixing plate is provided inside the housing near the exhaust pipe. One side of the fixing plate is fixedly connected to the housing. One end of the impeller faces the intake pipe, and the other end is rotatably connected to the fixing plate. The impeller is driven by a motor. The moisture-absorbing cylinder is disposed outside the impeller. One end of the moisture-absorbing cylinder is fixedly connected to the fixed plate, and the other end of the moisture-absorbing cylinder is fixedly connected to the inner wall of the housing near the air inlet pipe. An exhaust channel is formed between the moisture-absorbing cylinder and the fixed plate, and the exhaust channel is connected to the exhaust pipe.
[0005] Furthermore, a guide vane is provided at one end of the air intake pipe near the housing, and the outer wall of the guide vane is fixedly connected to the inner wall of the air intake pipe.
[0006] Furthermore, the blades of the guide vane are inclined toward the inner wall of the intake pipe along the air intake direction.
[0007] Furthermore, the moisture-absorbing cylinder includes a surface absorbent film, a middle absorbent layer, and a bottom absorbent film, from the inside out.
[0008] Furthermore, the surface absorbent membrane is a MOF-806 framework, the middle absorbent layer is a vertical carbon nanotube array, and the bottom absorbent membrane is a hydrophobic ceramic membrane.
[0009] Furthermore, a water collection tank is provided on one side of the exhaust channel of the housing, and a drain pipe connected to the water collection tank is provided on the end face of the housing near the air inlet pipe.
[0010] Furthermore, the drain pipe is equipped with a drain valve.
[0011] Furthermore, the impeller is a hydrocyclone impeller.
[0012] The beneficial effects of this utility model are: 1. The impeller is driven by a motor to rotate, allowing air to enter the moisture absorption cylinder through the intake pipe. The humid air is then absorbed by the moisture absorption cylinder and enters the exhaust channel. The dry air is discharged through the exhaust channel to the exhaust pipe, so that the engine can obtain dry air, effectively reducing the humidity of the engine intake air and improving combustion stability.
[0013] 2. Under the action of the guide vanes, the air entering the moisture absorption cylinder can generate a pre-swirling flow. The impeller enhances the air intake swirling flow in the moisture absorption cylinder, thereby enabling the humid air and the moisture absorption cylinder to evenly and fully adsorb the moisture in the air. This utility model dehumidifies through a two-stage centrifugal separation method, which can efficiently remove gaseous water and liquid water in high humidity environments.

[0022] Please also see Figures 1 to 4 The preferred embodiment of the present invention is an engine intake centrifugal adsorption synergistic dehumidification device, which includes a housing 1, an impeller 2 and a moisture absorption cylinder 3.
[0023] An air inlet pipe 101 and an exhaust pipe 102 are respectively provided at both ends of the housing 1. A fixing plate 11 is provided inside the housing 1 near the exhaust pipe 102. One side of the fixing plate 11 is fixedly connected to the housing 1. One end of the impeller 2 faces the air inlet pipe 101, and the other end is rotatably connected to the fixing plate 11. The impeller 2 is driven by a motor 21. In this embodiment, the impeller 2 is a hydrocyclone impeller. The motor 21 is fixed to the side of the fixing plate 11 near the exhaust pipe 102, and the output shaft of the motor 21 passes through the fixing plate 11 and is fixedly connected to the impeller 2. In this embodiment, the fixing plate 11 is fixedly connected to the inner wall of the housing 1 by a connecting rod 111.
[0024] A guide vane 4 is provided at one end of the intake pipe 101 near the housing 1, and the outer wall of the guide vane 4 is fixedly connected to the inner wall of the intake pipe 101. In this embodiment, the blades of the guide vane 4 are inclined toward the inner wall of the intake pipe 101 along the intake direction, and the guide vane 4 is made of stainless steel with a 25° tilt angle pre-swirl.
[0025] The moisture-absorbing cylinder 3 is disposed outside the impeller 2. One end of the moisture-absorbing cylinder 3 is fixedly connected to the fixing plate 11, and the other end of the moisture-absorbing cylinder 3 is fixedly connected to the inner wall of the housing 1 near the air inlet pipe 101. The moisture-absorbing cylinder 3 and the fixing plate 11 form an exhaust channel 103, and the exhaust channel 103 is connected to the exhaust pipe 102. In this embodiment, one end of the moisture-absorbing cylinder 3 is electrically connected to the air inlet pipe 101.
[0026] The impeller 2 is driven by motor 21 to rotate, allowing air to enter the moisture-absorbing cylinder 3 through the intake pipe 101. Simultaneously, under the action of guide vanes 4, the air entering the moisture-absorbing cylinder 3 generates a pre-swirling flow. The impeller 2 enhances the intake swirling flow of air within the moisture-absorbing cylinder 3. The humid air, after being absorbed by the moisture-absorbing cylinder 3, enters the exhaust channel 103, and the dry air is discharged through the exhaust channel 103 to the exhaust pipe 102. This ensures the engine receives dry air, effectively reducing the humidity of the engine intake air and improving combustion stability. This embodiment uses a two-stage centrifugal separation method for dehumidification, enabling efficient removal of both gaseous and liquid water in high-humidity environments.
[0027] In this embodiment, the moisture-absorbing cylinder 3 includes, from the inside out, a surface moisture-absorbing film 31, a middle moisture-absorbing layer 32, and a bottom moisture-absorbing film 33. The surface moisture-absorbing film 31 is a MOF-806 framework capable of capturing 0.9 nm gaseous water molecules; the middle moisture-absorbing layer 32 is a vertical carbon nanotube array capable of capillary condensation of mesoscale water vapor; and the bottom moisture-absorbing film 33 is a hydrophobic ceramic film capable of blocking residual water vapor. Humid air is dehumidified by sequentially passing through the surface moisture-absorbing film 31, the middle moisture-absorbing layer 32, and the bottom moisture-absorbing film 33.
[0028] like Figure 1 As shown, a water collection tank 5 is provided on one side of the exhaust channel 103 of the housing 1, and a drain pipe 51 connected to the water collection tank 5 is provided on the end face of the housing 1 near the air inlet pipe 101. The drain pipe 51 is equipped with a drain valve 52.
[0029] In this embodiment, the water collection tank 5 is located at the lowest position of the housing 1. The side of the water collection tank 5 facing the moisture absorption cylinder 3 is open. When the humidity in the moisture absorption cylinder 3 is too high, the water in the moisture absorption cylinder 3 flows into the water collection tank 5 under the action of gravity. By opening the drain valve 52, the water in the water collection tank 5 can be discharged.
[0030] like Figure 4 The diagram shows the airflow direction during the dehumidification process. The moisture absorption process of the engine intake centrifugal adsorption synergistic dehumidification device in this embodiment is as follows: Motor 21 drives impeller 2 to rotate. Air enters the moisture absorption cylinder 3 through intake pipe 101 and guide vane 4, generating a pre-swirling flow. Then, impeller 2 enhances the intake swirling flow of air in moisture absorption cylinder 3, so that the moist air passes through the surface water absorption film 31, the middle water absorption layer 32 and the bottom water absorption film 33 in sequence and enters the exhaust channel 103. Dry air is discharged through exhaust channel 103 to exhaust pipe 102, so that the engine can obtain dry air.
