Description

Technical Field

[0001] The invention relates to the technical field of air compressor dehydration, and in particular to a compressed air condensation dehydration device. Background Art

[0002] The compressed air produced by the compressor is not pure. The compressed air in nature is prepared by the air compressor and stored in the air tank. Due to the design of the air compressor, it is inevitable that some water is mixed in the air. The hazards caused by water in the compressed air are mainly manifested in: condensed water on the pneumatic equipment will take away the lubricating oil, causing the equipment efficiency to decrease or even damage. Condensed water will also accelerate the wear of the valves in the pipeline, causing the pneumatic control equipment to fail or misoperate; it will cause the pipeline and equipment to rust. If water freezes at the low point of the pipeline, the pipeline is also in danger of bursting. If there is water mist in the compressed air used for spraying, it will affect the adhesion of the paint on the workpiece and cause the coating to fail. During the compression process, the moisture in the air may mix with the lubricating oil, resulting in a decrease in lubrication efficiency, increased wear of machine parts, and may cause poor sealing and deterioration and emulsification of the lubricating oil.

[0005] The present invention provides a plurality of parallel partitions, each of which is provided with a plurality of dewatering bends. When the airflow with moisture passes through the gap between adjacent partitions, the airflow hits the dewatering bends, causing the moisture in the airflow to quickly contact the partitions and condense, thereby capturing the water mist in the airflow.

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The present application provides a compressed air condensation and water removal device, as shown below Figure 1 Elaborate in detail.

[0023] A compressed air condensation and dewatering device comprises a tank body 1, an air inlet 2 is arranged on the side wall of the tank body 1, an exhaust port 3 is arranged on the top of the tank body 1, a drain port 4 is arranged on the bottom wall, a plurality of partition plates 5 are arranged in parallel inside the tank body 1, the partition plates 5 are arranged in parallel along the direction from the drain port 4 to the exhaust port 3, and each partition plate 5 comprises an integrally connected main body plate 51 and a dewatering bend 52, each partition plate 5 comprises a plurality of dewatering bends 52, a serpentine channel 6 for gas to pass through is formed between two adjacent partition plates 5, and an auxiliary dewatering structure 7 is arranged on the inner wall of the tank body 1.

[0024] The present invention provides a plurality of parallel partitions 5, each of which is provided with a plurality of dewatering bends 52. When the airflow with moisture passes through the gap between adjacent partitions 5, the airflow hits the dewatering bends 52, causing the moisture in the airflow to quickly contact the partitions 5 and condense, thereby capturing the water mist in the airflow. The condensed water flows down along the partitions 5 to the drain port 4 and is discharged from the tank body 1.

[0025] In one embodiment, the water removal bend 52 includes a first fold plate 521, a second fold plate 522 and a vertical plate 523;

[0026] The vertical plate 523 is arranged parallel to the main body of the partition plate 5, and the first folding plate 521 and the second folding plate 522 are symmetrically arranged at both ends of the vertical plate 523. The first folding plate 521 and the second folding plate 522 are integrally connected to the main plate 51, and the first folding plate 521, the second folding plate 522 and the vertical plate 523 are integrally connected.

[0027] The arrangement of the first folding plate 521, the second folding plate 522 and the vertical plate 523 can form a serpentine channel 6. After the airflow moves to the first folding plate 521 or the second folding plate 522 in the serpentine channel 6, the airflow turns after the collision, and vortices are easily generated at the corners of the airflow, so that the airflow generates centrifugal force at the corners, and further pushes the water mist in the air to the partition plates 5, the first folding plate 521, the second folding plate 522 and the vertical plate 523 on both sides, so as to further capture the water mist.

[0028] The dewatering efficiency increases with the increase of air flow velocity, because the high flow velocity causes a large inertial force on the droplets, which is conducive to the separation of gas and liquid. However, the increase of flow velocity will increase the system resistance and energy consumption. Moreover, there is a certain limit to the increase of flow velocity. Too high flow velocity will cause secondary water, thereby reducing the dewatering efficiency. Therefore, it is necessary to control the air flow rate. In some embodiments, the air inlet 2 is connected to an air intake pipe, and a flow control valve is provided on the air intake pipe to adjust the flow rate of the gas entering the tank body 1.

[0029] In some embodiments, the width of the first folded plate 521 projected in the horizontal direction is 1 / 2 of the distance between two adjacent partition plates 5, and the width of the second folded plate 522 projected in the horizontal direction is 1 / 2 of the distance between two adjacent partition plates 5. The horizontal projections of the first folded plate 521 and the second folded plate 522 occupy 1 / 2 of the distance between adjacent partition plates 5, which effectively provides an impact area for the airflow, thereby ensuring the first folded plate 521 and the second folded plate 522 to capture the water mist.

[0030] In one embodiment, when the airflow hits the first folding plate 521, a portion of the water mist inside it is captured. However, in order to ensure that the airflow has sufficient inertia to flow in the exhaust port 3 so that the second folding plate 522 can also capture enough water mist, the angle between the first folding plate 521 and the vertical plate 523 is greater than the angle between the second folding plate 522 and the vertical plate 523, and the angle between the first folding plate 521 and the vertical plate 523 is not less than 120°, and the angle between the second folding plate 522 and the vertical plate 523 is not less than 120°.

[0031] This embodiment can make the distance between the two first folding plates 521 facing each other larger than the distance between the two second folding plates 522 facing each other, so that the airflow can maintain sufficient inertia to smoothly pass through the channel between the two first folding plates 521. When passing through the channel between the two second folding plates 522, its collision area increases, so that the second folding plates 522 can capture more water mist, and because the distance between the two second folding plates 522 becomes smaller, the airflow velocity increases, so that the passing airflow has greater inertia again to rush to the next dewatering bend, thereby ensuring the dewatering efficiency of each group of dewatering bends 52.

[0032] In one embodiment, the length of the main plate 51 between different groups of dewatering bends 52 on the same partition plate 5 is not less than the length of the vertical plates 523 of the adjacent dewatering bends 52 on both sides. The number of times the airflow is obstructed during a period of time is reduced, so that the airflow can pass through the gaps between the partition plates 5 normally.

[0033] In one embodiment, the auxiliary water removal structure 7 includes a cooling cavity 71 arranged in the hollow of the inner wall of the tank body 1, a coolant is arranged in the cooling cavity 71, and the cooling cavity 71 is connected to a constant temperature cooling device 72. The provision of the coolant can make the water mist contacting the inner wall of the tank body 1 directly condense into water droplets; on the other hand, since the multiple partitions 5 are directly mounted on the inner wall of the tank body 1, the inner wall of the tank body 1 can absorb and transfer the heat of the multiple partitions 5, so that the temperature of the multiple partitions 5 can be maintained at a relatively low temperature for a long time, so that the water mist in the airflow is convenient to condense when it hits the water removal bend or contacts the side wall of the partition 5, thereby accelerating the capture of the water mist in the airflow.

[0034] In one embodiment, the temperature of the coolant is maintained at 0-2° C. This can effectively realize the rapid condensation of the water mist and simultaneously realize the rapid heat conversion of the partition plate 5 to ensure that the partition plate 5 is at a relatively low temperature.

[0035] In one embodiment, the drain port 4 is connected to a recovery pool 8, and an automatic drain valve 81 is provided on the pipe connected to the drain port 4. The condensate in the tank 1 can be directly passed into the recovery pool 8, and the automatic drain valve 81 can adjust the condensate flow in the pipe.

[0036] In one embodiment, no more than three dewatering bends 52 are provided on each partition plate 5. The provision of multiple dewatering bends 52 can ensure that the moisture content in the gas discharged from the exhaust port 3 is extremely low. However, the provision of too many dewatering bends 52 will produce condensed water in multiple locations. When the airflow moves at high speed, the condensed water at the dewatering bends 52 will be carried away again to produce secondary water carrying. Therefore, under the premise of ensuring the dewatering efficiency, too many dewatering bends 52 that are prone to water storage should not be provided, and no more than three dewatering bends 52 should be provided on each partition plate 5.

[0037] In one embodiment, the height of the air inlet 2 is lower than the height of the end of the partition plate 5 toward the drain port 4. This ensures that the airflow with water mist can completely pass through the serpentine channel 6 formed by the multiple partition plates 5, thereby further improving the capture effect of water mist in the airflow.
