Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, and in particular to a high-efficiency water-gas separation heat exchanger. Background Technology
[0002] Excessive moisture content in compressed air directly affects air ducts and equipment using compressed air. In pneumatic equipment, condensation can wash away lubricating oil, reducing equipment efficiency or even causing damage. Condensation also accelerates wear on valves in the pipeline, causing malfunctions or misoperations of pneumatic control equipment; it can also cause corrosion in pipelines and equipment, and if water accumulates and freezes at low points in the pipeline, there is a risk of pipeline bursting. If water mist is present in the compressed air used for spraying, it will affect the adhesion of paint to the workpiece, leading to coating failure. To minimize the moisture content of the compressed air produced by the air compressor, it is necessary to achieve a good air-water separation effect during the hot air condensation process. Utility Model Content
[0003] To solve the above technical problems, this utility model provides a high-efficiency water-gas separation heat exchanger, including a core and an inlet end cap and an outlet end cap respectively located at both ends of the core. The outlet end cap includes a condensate outlet and an air outlet. A wire mesh is provided inside the outlet end cap above the condensate outlet. A horizontal straight pipe is provided above the wire mesh. The straight pipe has a number of air holes spaced apart along its length, with the openings of the air holes facing upwards. A vertical pipe is vertically connected to one end of the straight pipe along its length. The bottom of the vertical pipe passes through the wire mesh and is connected to the air outlet. The airflow passes through the straight pipe, the vertical pipe, the air holes, and the air outlet in sequence before being discharged.
[0004] The further defined technical solution of this utility model is:
[0005] Furthermore, a vertical bending baffle is fixed inside the outlet end cap. The bending baffle is located on the side of the vertical tube closest to the core, and the included angle of the bending baffle on the side of the vertical tube is set between 135 and 160 degrees.
[0006] As described above, a high-efficiency water-gas separation heat exchanger has several spaced fixing strips on the side of the wire mesh away from the straight tube, and the fixing strips are fixed inside the outlet end cap.
[0007] As described above, a high-efficiency water-gas separation heat exchanger has several diamond-shaped holes evenly arranged on a steel wire mesh.
[0008] As described above, a high-efficiency water-gas separation heat exchanger has rounded corners at the connection points of adjacent inner walls within the rhomboid holes.
[0009] As described above, in a high-efficiency water-gas separation heat exchanger, straight tubes are arranged along the width direction of the core.
[0010] As described above, in a high-efficiency water-gas separation heat exchanger, the air pores are evenly spaced along the length of the straight tube.
[0011] As described above, a high-efficiency water-gas separation heat exchanger has two straight tubes, which are spaced apart along the height of the vertical tube.
[0012] As described above, a high-efficiency water-gas separation heat exchanger has two straight pipes spaced apart along the height of the vertical pipe. The upper straight pipe is connected to the top of the vertical pipe, and the length of the upper straight pipe is greater than the length of the lower straight pipe.
[0013] As described above, in a high-efficiency water-gas separation heat exchanger, the number of air holes on the upper straight tube is greater than the number of air holes on the lower straight tube.
[0014] The beneficial effects of this utility model are:
[0015] (1) In this utility model, hot and humid air enters the high-efficiency water vapor separation heat exchanger of this embodiment after being discharged from the compressor. After being cooled by the core, the temperature is cooled to the required temperature. Then it enters the outlet head. When passing through the straight tube inside the outlet head, the air velocity is used to form centrifugal force to separate a part of the water vapor and air. Then, after passing through the wire mesh on the side of the condensate outlet, the water vapor is further condensed and discharged from the condensate outlet, thereby making the water vapor separation effect of the entire heat exchanger more excellent.
[0016] (2) In this utility model, the setting of the bending baffle allows hot air to be guided to other spaces inside the outlet head when it enters from the core, so that vortices are not formed on the straight pipe side, thus not affecting the normal flow of airflow, and not affecting the efficiency and fullness of water vapor separation.
[0017] (3) In this utility model, the setting of the fixing strip makes it easier and more secure to install the wire mesh above the condensate drain outlet; the setting of the diamond-shaped hole can enhance the condensation effect of the wire mesh, and the rounded corner setting of the inner wall of the diamond-shaped hole further enhances the condensation effect of the wire mesh.
[0018] (4) In this utility model, the double straight pipe can generate double the centrifugal force, thereby making the water vapor separation of the entire heat exchanger more thorough and further improving the efficiency of water vapor separation. Attached Figure Description

[0024] Example 1: This example provides a high-efficiency water-gas separation heat exchanger, such as... Figures 1 to 3 As shown, it includes a core 1 and an inlet end cap 2 and an outlet end cap 3 respectively located at both ends of the core 1. The outlet end cap 3 includes a downward-facing condensate drain outlet 31 and an air outlet 32.
[0025] The outlet end cap 3 is provided with a wire mesh 4 horizontally located above the condensate drain outlet 31. The wire mesh 4 has a number of diamond-shaped holes 41 evenly arranged, and the connection between adjacent inner walls of the diamond-shaped holes 41 is rounded. The side of the wire mesh 4 away from the straight pipe 5 is also provided with a number of spaced fixing strips 42. The fixing strips 42 are fixed inside the outlet end cap 3 and are spaced at equal intervals along the width direction of the wire mesh 4.
[0026] Above the wire mesh 4 is a horizontal straight tube 5 that is arranged along the width of the core 1. The straight tube 5 has a number of air holes 51 spaced at equal intervals along its length, with the openings of the air holes 51 facing upwards.
[0027] One end of the straight pipe 5 is closed along its length, and the other end is vertically connected to the vertical pipe 6. The top of the vertical pipe 6 is closed, and the bottom of the vertical pipe 6 passes through the wire mesh 4 and is connected to the air outlet 32. The airflow passes through the straight pipe 5, the vertical pipe 6, the air hole 51 and the air outlet 32 in sequence to be discharged. The airflow enters the core 1 from the inlet end cap 2, then flows from the core 1 into the outlet end cap 3, and then passes through the straight pipe 5 and the vertical pipe 6 to generate centrifugal force and is thrown onto the wire mesh 4 to condense before passing through the air hole 51 and exiting from the pipe and the air outlet 32.
[0028] A vertical bending baffle 7 is also fixed inside the outlet end cap 3. The bending baffle 7 is located on the side of the vertical pipe 6 near the core 1, and the included angle of the bending baffle 7 on the side of the vertical pipe 6 is set to 150 degrees. The setting of the bending baffle 7 allows hot air to enter the outlet end cap 3 from the core 1 and be directed to other spaces inside the outlet end cap 3 by the bending baffle 7, so that vortices will not be formed on the side of the straight pipe 5, thus not affecting the normal flow of air, and not affecting the efficiency and fullness of water vapor separation.
[0029] After being discharged from the compressor, the hot and humid air enters the high-efficiency water vapor separation heat exchanger of this embodiment. After being cooled by the core 1, the temperature is cooled to the required temperature. Then it enters the outlet head 3. When passing through the straight tube 5 inside the outlet head 3, the air flow rate forms centrifugal force to separate a portion of the water vapor and air. Then it passes through the wire mesh 4 on the side of the condensate outlet 31 to further condense the water vapor before being discharged from the condensate outlet 31.
[0030] Example 2: This example provides a high-efficiency water-gas separation heat exchanger, including a core 1 and an inlet end cap 2 and an outlet end cap 3 respectively disposed at both ends of the core 1. The outlet end cap 3 includes a downward-facing condensate drain outlet 31 and an air outlet 32.
[0031] The outlet end cap 3 is provided with a wire mesh 4 horizontally located above the condensate drain outlet 31. The wire mesh 4 has a number of diamond-shaped holes 41 evenly arranged, and the connection between adjacent inner walls of the diamond-shaped holes 41 is rounded. The side of the wire mesh 4 away from the straight pipe 5 is also provided with a number of spaced fixing strips 42. The fixing strips 42 are fixed inside the outlet end cap 3 and are spaced at equal intervals along the width direction of the wire mesh 4.
[0032] Above the wire mesh 4 is a horizontal straight pipe 5 arranged along the width of the core 1. The straight pipe 5 has several air holes 51 spaced at equal intervals along its length, with the openings of the air holes 51 facing upwards. The bottom of the vertical pipe 6 passes through the wire mesh 4 and is connected to the air outlet 32. The airflow passes through the straight pipe 5, the vertical pipe 6, the air holes 51 and the air outlet 32 in sequence before being discharged. The airflow enters the core 1 from the inlet end cap 2, then flows from the core 1 into the outlet end cap 3, and then passes through the straight pipe 5 and the vertical pipe 6 to generate centrifugal force, which throws it onto the wire mesh 4, condenses it, and then passes through the air holes 51 and exits from the pipe and the air outlet 32.
[0033] like Figure 4 As shown, two straight pipes 5 are spaced apart along the height direction of the vertical pipe 6. The upper straight pipe 5 is connected to the top of the vertical pipe 6, and the length of the upper straight pipe 5 is greater than that of the lower straight pipe 5. The number of air holes 51 opened on the upper straight pipe 5 is greater than that opened on the lower straight pipe 5.
[0034] The double straight tube configuration generates double the centrifugal force, resulting in more thorough water-vapor separation in the entire heat exchanger and further improving the efficiency of water-vapor separation.
[0035] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
