Description
Technical Field
[0001] This utility model relates to the technical field of gas-water separation equipment, and in particular to a gas-water separation device for saturated compressed air in an air compressor station. Background Technology
[0002] An air compressor station, also known as a compressed air depressurization station, is a device that compresses air to a certain pressure and is widely used in industry, agriculture, transportation, and other fields. Establishing air compressor stations to centrally supply compressed air to enterprises has become a development trend in recent years. Some industrial parks and large enterprises are gradually building their own air compressor stations. However, when air at normal temperature and pressure is compressed into compressed air at a certain pressure by a compressor, its temperature rises. Compressed air usually needs to be cooled to near room temperature before use. After cooling, the compressed air will be saturated below its pressure dew point temperature, resulting in the precipitation of liquid water mixed in with the compressed air. Therefore, how to centrally separate water from compressed air at the supply end is a crucial technical problem that must be solved to ensure the normal use of compressed air. Currently, the main methods for water separation in compressed air are to first use a refrigerated dryer or adsorption dryer for drying, and then use a filter for separation. However, these separation methods involve complex equipment structures and have relatively high construction and operating costs. Utility Model Content
[0003] The purpose of this invention is to provide a gas-water separation device for saturated compressed air in an air compressor station. This device can solve the problem that existing technologies for separating water from saturated compressed air use complex equipment structures and have high costs in terms of construction and operation.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: This air-water separation device for saturated compressed air in an air compressor station includes a cylindrical body with a compressed air inlet, a compressed air outlet at the top of the cylindrical body, and a drain outlet at the bottom; a guide tube is provided inside the cylindrical body, and a gap is provided between the outer side wall of the guide tube and the inner side wall of the cylindrical body; a wire mesh demister is provided above the guide tube inside the cylindrical body, and a water guide plate is provided below the guide tube, with multiple through holes on the water guide plate.
[0005] A more specific technical solution than the above-mentioned technical solution is that the guide tube has a guide portion that is larger at the top and smaller at the bottom, and the top of the guide portion is connected to the inner wall of the tube body.
[0006] Furthermore, the horizontal height of the water guide plate gradually decreases from the center to the edge.
[0007] Furthermore, the plurality of through holes are equidistantly arranged along the circumferential edge of the water guide plate.
[0008] Furthermore, the bottom of the cylinder is a downward-curved arc shape.
[0009] Furthermore, a cross pressure plate is provided above the wire mesh demister inside the cylinder body, and a cross support is provided below the wire mesh demister.
[0010] Furthermore, the compressed air inlet is connected to the middle of the cylinder body via a reducing pipe, and a reinforcing ring is provided at the connection between the reducing pipe and the cylinder body.
[0011] Furthermore, the top of the cylinder is provided with a head cover, which is connected to the cylinder by bolts, and the compressed air outlet is located on the head cover.
[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0013] 1. This utility model not only improves the quality of compressed air provided to users by the air compressor station, but also does not require increased energy consumption or the energy consumption of the compressor itself. In addition, it has a simple structure, is safe and convenient to install and use, and has a long service life. After practical application, compared with the original gas-water separation method, the cost and operating cost are reduced by at least 50%.
[0014] 2. In operation, this invention involves connecting saturated compressed air mixed with liquid water from an air compressor station to the compressed air inlet. The compressed air then enters the cylinder body through a reducer. After acceleration due to the reducer, the compressed air first rotates along the annular channel between the outer wall of the guide tube and the inner wall of the cylinder body, creating centrifugal separation. Large water droplets flow downwards along the inner wall of the cylinder body onto the water guide plate, and then flow through the through-holes of the water guide plate to the drain outlet, completing the first separation. Then, the gas flows upwards from inside the guide tube, and under the influence of gravity, small water droplets separate from the gas and fall onto the water guide plate. The water then flows through the through-holes of the guide plate to the drain outlet, completing the second separation. At this point, the granular water droplets are basically separated, and the remaining free fine water mist passes through the wire mesh demister together with the gas. After the wire mesh demister, the fine water mist gathers into larger water droplets, which separate from the gas under the action of gravity and fall onto the guide plate. The water then flows through the through-holes of the guide plate to the drain outlet, completing the third separation. The compressed air, after three gas-water separations, is discharged from the compressed air outlet, completing the entire process and removing the liquid water mixed in the saturated compressed air of the air compressor station.
[0015] 3. A head cover is installed at the top of the cylinder body, which is connected to the cylinder body by bolts, allowing for easy replacement of the wire mesh demister. A cross-shaped pressure plate and cross-shaped bracket are used to secure the wire mesh demister. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
[0020] like Figures 1 to 3 The air-water separation device for saturated compressed air in the air compressor station shown includes a cylindrical body 1 with a compressed air inlet 2, a compressed air outlet 3 at the top of the cylindrical body 1 and a drain outlet 4 at the bottom; a guide tube 5 is provided inside the cylindrical body 1, and there is a gap between the outer side wall of the guide tube 5 and the inner side wall of the cylindrical body 1; a wire mesh demister 6 is provided above the guide tube 5 inside the cylindrical body 1, and a water guide plate 7 is provided below the guide tube 5. The water guide plate 7 has multiple through holes 7-1, and the horizontal height of the water guide plate 7 gradually decreases from the middle to the edge. The multiple through holes 7-1 are equidistantly arranged along the circumferential edge of the water guide plate 7.
[0021] The guide tube 5 has a guide part 5-1 at the top that is larger at the top and smaller at the bottom, and the top of the guide part 5-1 is connected to the inner wall of the tube body 1.
[0022] Inside the cylinder body 1, a cross pressure plate 8 is provided above the wire mesh demister 6, and a cross support 9 is provided below the wire mesh demister 6.
[0023] The compressed air inlet 2 is connected to the middle of the cylinder body 1 through the reducer pipe 10, and a reinforcing ring 11 is provided at the connection between the reducer pipe 10 and the cylinder body 1.
[0024] The bottom of the cylinder body 1 is curved downwards, and the top of the cylinder body 1 is provided with a head cover 12. The compressed air outlet 3 is located on the head cover 12.
[0025] The bottom of the cylinder body 1 is provided with multiple adjustable support feet 13 for adjusting the height of the cylinder body 1; the outer wall of the cylinder body 1 is provided with a nameplate holder 14 for installing pressure vessel nameplates.
[0026] In operation, this invention involves connecting saturated compressed air from an air compressor station, mixed with liquid water, to the compressed air inlet 2. The compressed air then enters the cylinder 1 via a reducer 10. After acceleration due to the reducer, the compressed air first rotates along the annular channel between the outer wall of the guide cylinder 5 and the inner wall of the cylinder 1, creating centrifugal separation. Large water droplets flow downwards along the inner wall of the cylinder 1 onto the water guide plate 7, and then through the through-hole 7-1 of the water guide plate 7 to the drain outlet 4, completing the first separation. Then, the gas flows upwards from the guide cylinder 5, and under the influence of gravity, small water droplets separate from the gas and fall onto the water guide plate 7. The water then flows through the through-hole 7-1 of the water guide plate 7 to the drain outlet 4, completing the second separation. At this point, the granular water droplets are basically separated, and the remaining free fine water mist passes through the wire mesh demister 6 together with the gas. After the wire mesh demister, the fine water mist gathers into larger water droplets, which separate from the gas under the action of gravity and fall onto the water guide plate 7. The water then flows through the through-hole 7-1 of the water guide plate 7 to the drain outlet 4, completing the third separation. The compressed air after three gas-water separations is discharged from the compressed air outlet 3, completing the entire process and removing the liquid water mixed in the saturated compressed air of the air compressor station.
[0027] The cylinder body 1 is equipped with a head cover 12 at the top, which is connected to the cylinder body 1 by bolts, allowing for easy replacement of the wire mesh demister 6. The cross pressure plate 8 and the cross bracket 9 are used to fix the wire mesh demister 6.
[0028] This invention not only improves the quality of compressed air provided to users by the air compressor station, but also eliminates the need to increase energy consumption or consume the energy of the compressor itself. Furthermore, it has a simple structure, is safe and convenient to install and use, and has a long service life. After practical application, compared with the original gas-water separation method, the cost and operating cost are reduced by at least 50%.
