Description

Technical Field

[0001] The utility model relates to the technical field of compressor cooling, in particular to an anti-scaling device for a compressor cooler. Background Art

[0002] Hydrogen and nitrogen compressors use three stages of compression to gradually increase the compression ratio. The temperature of the gas after each stage of compression increases with the pressure, the compression ratio increases, and the temperature of the gas at the compressor outlet increases accordingly. According to process requirements, after each stage of gas compression, the gas needs to enter a cooler to reduce the gas temperature to below 40°C. Lowering the temperature reduces the gas density and increases the compressor's air output.

[0003] The three-stage gas outlet pressure of the compressor is generally 15-21.5MPa, and the three-stage outlet gas temperature is around 115℃. The high temperature easily makes the temperature of the outlet gas to the cooler high. The high gas temperature leads to high cooling water temperature, which is easy to form scale. Although the circulating cooling water has been treated by adding scale inhibitors and bactericides to control the water quality within the index, the treated scale is still in the circulating water. Although the circulating water has been replaced, some suspended matter still exists. After a long time, it will gather on a certain pipe wall and gradually increase, making the circulating water flow poor, forming scale, clogging the pipe, and affecting the normal use of the equipment. In order to prevent suspended matter from adhering to the pipe wall of the cooling water pipe for a long time, reducing the heat exchange effect, and increasing the compressor's air volume, this technology has been specially developed.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-3 As shown, the utility model provides a technical solution: a compressor cooler anti-scaling device, comprising a cooling tower 1 and a sedimentation chamber 2, an air inlet pipe 3 is installed on one side of the cooling tower 1, and a first switch valve 4 is provided on the air inlet pipe 3.

[0022] The top of the cooling tower 1 is respectively provided with a feeding port 5, a motor 8 and an exhaust pipe 6. The exhaust pipe 6 is provided with a second switch valve 7. The cooled gas is discharged through the exhaust pipe 6. The inner cavity of the cooling tower 1 is provided with a rotatable stirring shaft 9, which is driven by the motor 8 and has a scraper 10 installed on it.

[0023] A waste pipe 11 is installed at the bottom of the cooling tower 1, and an inverted rubber bowl 17 (inverted triangle, with a large bottom opening and a small top) is provided in the waste pipe 11. The rubber bowl 17 is deformed under water pressure to achieve waste discharge. The waste pipe 11 is connected to the sedimentation chamber 2, and a third switch valve 12 is provided on the waste pipe 11.

[0024] A filter screen 13 is provided at the upper portion of the inner cavity of the sedimentation chamber 2 , wherein the waste discharge pipe 11 is located above the filter screen 13 , and the inlet of the return water pipe 15 is located below the filter screen 13 .

[0025] A pump 14 is provided on the top of the sedimentation chamber 2 . The pump 14 is connected to the upper part of the cooling tower 1 through a return pipe 15 . A fourth switch valve 16 is provided on the return pipe 15 .

[0026] At the same time, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0027] During use, the high-temperature gas discharged from the compressor enters the cooling tower 1 through the air inlet pipe 3. The cooling tower 1 contains cooling water. Scale inhibitors and fungicides are added to the cooling tower 1 through the feeding port 5. Then, the motor 8 is started to drive the stirring shaft 9 to rotate, so that the cooling water is fully mixed with the scale inhibitors and fungicides, thereby achieving a certain anti-scaling purpose.

[0028] Furthermore, the rotation of the stirring shaft 9 will also drive the scraper 10 to rotate together. During the rotation process, the scraper 10 will scrape the scale on the inner wall of the cooling tower 1, thereby removing the scale.

[0029] Open the third switch valve 12, and the wastewater enters the sedimentation chamber 2 from the cooling tower 1 through the waste pipe 11. The suspended matter in the wastewater is filtered through the filter 13, and then enters the sedimentation chamber 2 for sedimentation and cooling. Finally, turn on the pump 14, and the clean water after cooling and filtering and sedimentation is reintroduced into the cooling tower 1 through the return pipe 15 to achieve the purpose of circulating cooling.

[0030] In order to prevent the suspended matter in the circulating water from flowing back into the cooling tower 1, a rubber bowl 17 is provided in the waste pipe 11. Figure 3 As shown, when the third switch valve 12 is closed, there is no water pressure on the upper end of the rubber bowl 17, so the rubber bowl 17 is in the left state (fully expanded). At this time, the suspended matter in the waste pipe 11 is blocked by the rubber bowl 17 and cannot enter the cooling tower 1. When the third switch valve 12 is opened, the rubber bowl 17 will be squeezed under the impact of water pressure, thereby forming the right state, and the wastewater in the cooling tower 1 can go straight down.

[0031] To sum up, the compressor cooler anti-scaling device, by providing a rotatable scraper structure, scrapes the inner wall of the cooling tower with the scraper to remove the scale, thereby solving the problem of reduced heat exchange effect caused by long-term adhesion of scale on the wall of the cooling water pipe. Furthermore, by providing an inverted rubber bowl in the waste pipe, the purpose of one-way control is achieved. The wastewater squeezes the rubber bowl under pressure and is discharged normally. When the wastewater at the bottom of the rubber bowl wants to flow back into the cooling tower, it will be blocked by the rubber bowl, thereby effectively preventing the scale in the circulating water from flowing back into the cooling tower, thereby avoiding the problem of pipe blockage.
