Abstract
Description
Technical Field
[0001] The utility model belongs to the field of condensers, and particularly relates to a water-precooled evaporative condenser. Background Art
[0002] The evaporative condenser belongs to one kind of condensers. It relies on the latent heat of vaporization of water evaporation to take away heat, and is used to cool the high-temperature and high-pressure steam discharged by the compressor, so that the refrigerant steam condenses in the pipe to provide a relatively low condensation temperature. Usually, the way of spraying cooling water on the heat dissipation pipes is adopted to cool the coolant in the heat dissipation pipes. After the heat dissipation pipes are used for a long time, the cooling water is sprayed on the outer periphery of the heat dissipation pipes, which easily causes scale formation on the outer wall of the heat dissipation pipes. If the attached scale is not cleaned for a long time, it will affect the heat exchange effect of the heat dissipation pipes. At present, usually, the heat dissipation pipes are scrubbed manually or chemical reagents are used to clean the outer periphery of the heat dissipation pipes. However, when using chemical reagents to clean the heat dissipation pipes, the chemical reagents are directly sprayed on the heat dissipation pipes, with a short residence time, and most of the chemical reagents directly fall from both sides of the heat dissipation pipes, and only a very small number of chemical reagents contact the bottom of the heat dissipation pipes, resulting in poor scale cleaning effect. Therefore, we designed a water-precooled evaporative condenser with good scale cleaning effect. Summary of the Utility Model

[0018] A water-precooled evaporative condenser, as shown in Figure 1 and 2As shown in Figures 3 and 4, it includes a box body 1. An air outlet 2 and an air inlet 3 are successively opened on the box body 1. The air outlet 2 is located at the top of the box body 1. There are two air inlets 3, which are respectively located on both sides of the lower part of the box body 1. A fan 4 is fixedly installed at the air outlet 2, and the fan 4 is fixedly installed on the box body 1. A vertical partition 5 is fixedly installed in the box body 1. The vertical partition 5 divides the box body 1 into a left cavity and a right cavity. Air inlets 3 are provided on the side walls of both the left cavity and the right cavity. The lower parts of the left cavity and the right cavity are communicated. First heat dissipation pipes 6 and second heat dissipation pipes 7 that are mutually communicated are successively fixedly provided on both sides of the vertical partition 5. The vertical partition 5 is located between the first heat dissipation pipe 6 and the second heat dissipation pipe 7. The first heat dissipation pipe 6 is communicated with the second heat dissipation pipe 7. A spraying mechanism is provided above the second heat dissipation pipe 7. One ends of the first heat dissipation pipe 6 and the second heat dissipation pipe 7 are successively communicated with a refrigerant inlet 8 and a refrigerant outlet 9. It is characterized in that: Tooth rings 10 are respectively rotatably installed on both sides of the horizontal pipe part of the second heat dissipation pipe 7. The tooth rings 10 are respectively connected to the outer periphery of the second heat dissipation pipe 7 through bearings. The adjacent tooth rings 10 on the same side are meshed and matched. An arc-shaped pipe 11 coaxial with the outer periphery of the horizontal pipe part of the second heat dissipation pipe 7 is provided at the bottom of the outer periphery of the horizontal pipe part of the second heat dissipation pipe 7. The corresponding arc-shaped pipe 11, tooth ring 10 and the horizontal pipe part of the corresponding second heat dissipation pipe 7 are coaxially arranged. The height of the arc-shaped pipe 11 is half of the horizontal pipe part of the second heat dissipation pipe 7. A brush 12 that is in sliding contact with the outer periphery of the second heat dissipation pipe 7 is provided in the arc-shaped pipe 11. A driving device capable of simultaneously driving the tooth rings 10 to rotate is provided on the box body 1. The diameter of the arc-shaped pipe 11 is smaller than the diameter of the tooth ring 10. When the tooth ring 10 drives the corresponding arc-shaped pipe 11 to rotate, interference will not be caused between the adjacent arc-shaped pipes 11. The structure of the utility model is simple and ingenious. During daily use, the arc-shaped pipe 11 can prolong the contact time between the cooling water and the second heat dissipation pipe 7, ensuring that the cooling water and the coolant to be cooled are fully heat-exchanged. When cleaning the outer periphery of the second heat dissipation pipe 7, the arc-shaped pipe 11 can drive the brush 12 to rotate, brush the outer periphery of the second heat dissipation pipe 7, and better clean the water scale, ensuring the cleaning effect of the water scale, being able to meet the actual requirements and being suitable for popularization.When using the present utility model, first, the coolant to be cooled is introduced into the first heat dissipation pipe 6 through the refrigerant inlet 8, and enters the second heat dissipation pipe 7 along the pipeline, and finally is discharged from the refrigerant outlet 9. During this process, the fan 4 draws air upward, and the cold air from the outside enters the box body 1 through the air inlet 3 and is finally discharged from the air outlet 2. When passing through the first heat dissipation pipe 6 and the second heat dissipation pipe 7, the coolant to be cooled can be air-cooled. At the same time, the spraying mechanism is started, and the spraying mechanism sprays the second heat dissipation pipe 7 to perform water-cooling on the second heat dissipation pipe 7. When it is necessary to clean the scale on the outer periphery of the second heat dissipation pipe 7, a chemical reagent is introduced into the spraying structure, and the spraying mechanism sprays the chemical reagent on the second heat dissipation pipe 7. At the same time, the driving device is controlled to drive the toothed ring 10 to rotate, the toothed ring 10 drives the arc-shaped pipe 11 to rotate, and the arc-shaped pipe 11 drives the brush 12 to rotate. The chemical reagent cooperates with the brush 12 to clean the scale on the outer periphery of the second heat dissipation pipe 7. After the cleaning is completed, the arc-shaped pipe 11 is located at the bottom of the horizontal pipe of the second heat dissipation pipe 7, and at this time, the driving device is controlled to stop rotating.

A limiting device capable of limiting the vertical plate 42 is provided on the box body 1. When it is necessary to clean the filter plate 22, release the limitation of the vertical plate 42 by the limiting device. At this time, pull the vertical plate 42 to pull the filter plate 22 out of the box body 1, and then clean the filter plate 22. After cleaning, insert the filter plate 22 back into the box body 1 and control the limiting device to limit it.
