Description

Technical Field

[0001] This utility model relates to the field of air source water removal equipment, and in particular to a compressed air water remover. Background Technology

[0002] When an air compressor is working, the temperature of the compressed air it discharges is very high. At this temperature, the water in the air exists in a gaseous state and cannot be separated from the compressed air. In many applications, this requires the use of a gas drying device to dry the compressed air. However, existing gas drying devices are complex in structure and expensive. Utility Model Content

[0003] To address the issues of complex structure and high cost in existing gas drying devices, this invention provides a compressed air dehydrator with a simple structure and low cost.

[0004] This utility model provides a compressed air dehumidifier, including a cylinder, a flow-limiting seat, an inner tube, and a filter element disposed within the inner tube. One end of the cylinder has an air inlet and an air outlet, and the other end has a drain outlet. The flow-limiting seat includes a flow-limiting plate, a guide plate spaced apart from the flow-limiting plate, and a hollow connecting pipe located at the center of the flow-limiting plate and the guide plate. One end of the hollow connecting pipe communicates with the air outlet, and the outer wall of the other end of the hollow connecting pipe has multiple annularly distributed air outlet holes. One end of the inner tube covers the hollow connecting pipe. One end of the connecting pipe has an air outlet and is detachably connected to the guide plate. The flow limiting plate has multiple annularly distributed vent holes. The diameter of the guide plate is smaller than the diameter of the flow limiting plate, and the end near the flow limiting plate has an annular guide slope that slopes towards the inner wall of the cylinder. A first air passage is formed between the inner wall of the cylinder and the inner tube, and a second air passage is formed between the inner tube and the hollow connecting pipe. Compressed air passes sequentially through the air inlet, the flow limiting plate, the guide plate, the first air passage, the second air passage, and the hollow connecting pipe before being discharged from the air outlet.

[0005] As a further improvement of this utility model, the cylinder includes an end cap, a bottom cap, and an outer tube.

[0016] like Figures 1 to 4 As shown, this utility model discloses a compressed air dehumidifier, including a cylinder 1, a flow-limiting seat 2, an inner tube 3, and a filter element 4 disposed within the inner tube 3. One end of the cylinder 1 has an air inlet 14 and an air outlet 15, and the other end has a drain outlet 16. The flow-limiting seat 2 includes a flow-limiting plate 21, a flow-guiding plate 22 spaced apart from the flow-limiting plate 21, and a hollow connecting pipe 23 located at the center of the flow-limiting plate 21 and the flow-guiding plate 22. One end of the hollow connecting pipe 23 communicates with the air outlet 15, and the outer wall of the other end of the hollow connecting pipe 23 has multiple annularly distributed air outlet holes 26. One end of the inner tube 3 covers the hollow connecting pipe 23 and has air outlet holes 26. One end of the 6 is detachably connected to the guide plate 22. The end face of the hollow connecting pipe 23 with the air outlet 26 is a sealed structure. The flow limiting plate 21 has a plurality of annularly distributed vent holes 24. The diameter of the guide plate 22 is smaller than the diameter of the flow limiting plate 21, and the end near the flow limiting plate 21 has an annular guide slope 25 inclined towards the inner wall of the cylinder 1. The inner wall of the cylinder 1 and the inner pipe 3 form a first air passage, and the inner pipe 3 and the hollow connecting pipe 23 form a second air passage. Compressed air passes through the air inlet 14, the flow limiting plate 21, the guide plate 22, the first air passage, the second air passage and the hollow connecting pipe 23 in sequence and is discharged from the air outlet 15.

[0017] In this utility model, the cylinder 1 includes an end cap 11, a bottom cap 12, and an outer tube 13. The end cap 11 and the bottom cap 12 respectively cover the two ends of the outer tube 13. The air inlet 14 and the air outlet 15 are respectively provided on both sides of the end cap 11. The end cap 11 is provided with a central connecting hole communicating with the air outlet 15 and a peripheral air inlet hole communicating with the air inlet 14. One end of the hollow connecting tube 23 is threadedly connected to the central connecting hole.

[0018] In this utility model, one end of the inner tube 3 is threadedly connected to the guide plate 22; the filter element 4 is a nano filter element, which can better filter out impurities in the gas; the end cap 11 is threadedly connected to one end of the outer tube 13; the bottom cap 12 is threadedly connected to the other end of the outer tube 13, and the drain outlet 16 is located at the center of the bottom cap 12.

[0019] During assembly, first connect the flow restrictor 2 to the air inlet of the end cap 11, then connect the inner tube 3 containing the nano filter core to the flow restrictor 2, then connect the outer tube 13 to the end cap 11, and finally connect the bottom cap 12 to the outer tube 13.

[0020] In operation, compressed air enters through the inlet 14 and flows through the vent 24 of the flow-limiting plate 21 and then through the guide plate 22. The vent 24 of the flow-limiting plate 21 increases the air velocity. As the air flows through the guide plate 22, it is ejected directly onto the inner wall of the outer tube 13 via the annular guide ramp 25, generating centrifugal force. After the high-speed compressed air hits the inner wall of the outer tube 13, the moisture in the air remains on the inner wall and flows downwards under its own gravity, achieving the purpose of separating moisture. Moreover, when the compressed air passes through the vent 24 at high speed, according to Bernoulli's principle, its velocity increases significantly, which leads to a decrease in pressure. This process involves the conversion of the air's internal energy into kinetic energy, resulting in a decrease in internal energy and thus a drop in temperature. In addition, as the air rapidly passes through the small holes, friction may occur with the hole walls, which also generates heat loss, further contributing to the temperature decrease. Additionally, if the air itself is under high pressure, the pressure drops sharply after passing through the small hole. This adiabatic expansion process also causes a temperature drop. After the temperature drops, the water vapor in the compressed air turns into condensate. The condensate will flow downwards through the inner wall of the outer pipe 13 under its own gravity and eventually be discharged through the drain port 16. The dried compressed gas will be filtered through the nano filter element and then flow through the air outlet 26 before being discharged through the air outlet 15. The nano filter element can filter impurities in the gas, ensuring cleaner exhaust gas. When the compressed air enters the hollow connecting pipe 23 from the inner pipe 3 through the air inlet, the compressed air undergoes a 90-degree bend before entering the hollow connecting pipe 23. The purpose of this is to utilize the principle of turbulence to avoid the siphon effect and to carry any water that has not been discharged in time into the central connecting hole.

[0021] This utility model has a simple structure, low cost, good water removal effect and high efficiency, and has a filtration function.

[0022] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
