Description

Technical Field

[0001] The present application relates to the field of gas-liquid separators, and in particular to a gas-liquid separator dedicated to low-temperature evaporators. Background Art

[0002] A low-temperature evaporator is a device that evaporates at low temperatures, usually with an operating temperature below 70°C. It is divided into two types: low-temperature negative pressure evaporation and low-temperature normal pressure evaporation. It is mainly used in industrial wastewater treatment, wastewater recycling and other fields. It uses physical low-temperature distillation technology to achieve wastewater treatment and recycling. A gas-liquid separator is often installed in the evaporator. Its main function is to separate steam and liquid inside the evaporator. In a heat pump or refrigeration system, the basic function of the gas-liquid separator is to separate and preserve the liquid in the return pipe to prevent liquid hammer in the compressor and damage to the compressor. When installing a conventional low-temperature evaporator, one end of the separation tube is connected to the steam source, and the bottom end of the separation tube is connected to a filter. The liquid in the separation tube is filtered with the help of the filter, and a drain valve is installed at the bottom end of the filter. The liquid is discharged after the drain valve is opened.

[0003] Regarding the above-mentioned related technologies, the inventors believe that when a conventional gas-liquid separator is in use, if the gas flow rate from the separator is large, it is easy for some liquid or mist to flow out with the gas, resulting in liquid accumulation at the rear gas discharge pipe, causing damage to the compressor in the evaporator and affecting the use effect of the gas-liquid separator.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0020] The following is combined with Figure 1 —4 Provide further details of this application.

[0021] The embodiment of the present application discloses a gas-liquid separator dedicated to a low-temperature evaporator, referring to Figure 1 - Figure 2, including a separation tube 1. During installation, one end of the separation tube 1 is connected to the steam source. The bottom end of the separation tube 1 is connected to the filter 2. The liquid in the separation tube 1 is filtered with the help of the filter 2, and a drain valve 3 is installed at the bottom end of the filter 2. After the drain valve 3 is opened, the liquid is discharged, and one end of the connecting tube 4 is connected to one end of the separation tube 1. A fixed cylinder 5 is installed on the inner wall of the connecting tube 4. The inner wall of the fixed cylinder 5 is rotatably connected to a shielding frame 7. A connecting hole 8 is opened on the inner wall of the shielding frame 7, and a number of sponge filter blocks 6 are clamped on the inner wall of the shielding frame 7, so that the gas connected to the connecting tube 4 can be filtered with the help of the filter block 6, effectively preventing the liquid and mist in the gas from flowing out with the gas, thereby improving the use effect of the gas-liquid separator.

[0022] Reference Figure 2 A motor 9 is installed on the top of the fixed cylinder 5, and the output end of the motor 9 is connected to the top of the shielding frame 7. The shielding frame 7 is rotated by means of the motor 9, so that the water filter block 6 that has been used for a period of time is flipped over to ensure the water filtering effect of the water filter block 6. A rotating frame 10 is installed on the output end of the motor 9, and the bottom end of the rotating frame 10 is connected to a push spring 11. The bottom end of the push spring 11 is fixedly installed with a limit block 12. The limit block 12 is clamped with the top of the fixed cylinder 5 by means of the push spring 11, so that when the motor 9 controls the shielding frame 7 to rotate, the water filter block 6 in the rotating frame 10 is kept docked with the connecting pipe 4.

[0023] Reference Figure 3 - Figure 4 , the fan 13 is installed at one end of the fixed cylinder 5, and the end of the fixed cylinder 5 away from the fan 13 is connected to the air outlet pipe 14. After the fan 13 is started, wind flow is generated, and the wind flow enters the air outlet pipe 14 from the connecting hole 8 in the shielding frame 7, thereby drying the liquid in the water filter block 6, effectively improving the drying speed of the water filter block 6, and facilitating timely replacement of the water filter block 6 on the other side after it becomes wet. The inner wall of the air outlet pipe 14 is rotatably connected with a shielding plate 15, and a fixed spring 16 is installed between the shielding plate 15 and the air outlet pipe 14. The fixed spring 16 pushes the shielding frame 7, and uses the shielding frame 7 to shield one end of the air outlet pipe 14, so as to prevent the gas in the connecting pipe 4 from leaking from the air outlet pipe 14 when the motor 9 controls the shielding frame 7 to rotate.

[0024] The implementation principle of the gas-liquid separator for low-temperature evaporator of the embodiment of the present application is as follows: by connecting one end of the connecting pipe 4 with one end of the separation pipe 1, a fixed cylinder 5 is installed on the inner wall of the connecting pipe 4, and the inner wall of the fixed cylinder 5 is rotatably connected to the shielding frame 7, and the inner wall of the shielding frame 7 is provided with a connecting hole 8, and the inner wall of the shielding frame 7 is clamped with a plurality of sponge material water filter blocks 6, so that the gas connected to the connecting pipe 4 can be filtered by the water filter blocks 6, effectively preventing the liquid and mist in the gas from flowing out with the gas. A motor 9 is installed on the top of the fixed cylinder 5, and the output of the motor 9 The end is connected to the top of the shielding frame 7 so that the shielding frame 7 can be rotated by means of the motor 9, thereby turning over the water filter block 6 that has been used for a period of time to ensure the water filtering effect of the water filter block 6. The output end of the motor 9 is equipped with a rotating frame 10, and the bottom end of the rotating frame 10 is connected to a push spring 11. The bottom end of the push spring 11 is fixedly installed with a limit block 12, so that the limit block 12 can be clamped with the top of the fixed cylinder 5 by means of the push spring 11, so that when the motor 9 controls the shielding frame 7 to rotate, the water filter block 6 in the rotating frame 10 is kept docked with the connecting pipe 4.

[0025] The fan 13 can also be installed at one end of the fixed cylinder 5, and the end of the fixed cylinder 5 away from the fan 13 is connected to the air outlet pipe 14, so that airflow can be generated after the fan 13 is started. The airflow enters the air outlet pipe 14 from the connecting hole 8 in the shielding frame 7, thereby drying the liquid in the water filter block 6, effectively improving the drying speed of the water filter block 6, and facilitating timely replacement of the water filter block 6 on the other side after it becomes wet. The inner wall of the air outlet pipe 14 is rotatably connected to a shielding plate 15, and a fixed spring 16 is installed between the shielding plate 15 and the air outlet pipe 14, so that the fixed spring 16 can push the shielding frame 7, and use the shielding frame 7 to shield one end of the air outlet pipe 14, so as to prevent the gas in the connecting pipe 4 from leaking from the air outlet pipe 14 when the motor 9 controls the shielding frame 7 to rotate.

[0026] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
