At the same time, when the water inlet temperature is medium, the transport flow rate of the evaporation gas can be adaptively adjusted to a suitable flow value by the method of single gas transmission through the suction gas transmission pipeline. Moreover, when the water inlet temperature is low, the transport flow rate of the evaporation gas can be adaptively adjusted to a suitable flow value by the method of gas transmission through the direct-connection gas transmission pipeline and the suction gas transmission pipeline together. See the following for details.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

A pipeline pump for providing power for suction gas transmission is installed at the middle section of the suction gas transmission pipeline. Both ends of the suction gas transmission pipeline and the direct-connection gas transmission pipeline are fixedly connected and communicated with gas transmission elbows through pipe joints. The lower ends of the gas transmission elbows corresponding to the same end of the suction gas transmission pipeline and the direct-connection gas transmission pipeline are fixedly connected and communicated with vertically arranged air outlet connecting pipes through the pipe joints.

[0013] Using the above-mentioned octafluoropropane finished product filtration device, during the process of filtering and purifying the octafluoropropane finished product by evaporation and condensation, since the dual-channel gas transmission component is arranged between the evaporator body and the condenser body, and the dual-channel gas transmission component is respectively the direct-connected gas transmission pipeline and the suction gas transmission pipeline. Then, when the water inlet temperature is high, such as in summer, the valve of the air outlet connection pipe corresponding to the suction gas transmission pipeline is closed, and then the valve of the air outlet connection pipe corresponding to the direct-connected gas transmission pipeline is opened. In this way, the transmission flow rate of the evaporation gas provided by the evaporator body can be adjusted to a suitable flow rate value by the method of single gas transmission through the direct-connected gas transmission pipeline.

Specific implementation mode

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope protected by the present utility model.

[0025] See Figures 1-5As shown in the figure, the present utility model provides a finished octafluoropropane filtering device, which includes an evaporator body 2 and a condenser body 3. A discharge pipe 201 and an intake connection pipe 302 are vertically arranged at the top of the evaporator body 2 and the top of the condenser body 3 respectively. A dual-channel gas transmission component 1 is fixedly connected between the discharge pipe 201 and the intake connection pipe 302 to adjust the transmission flow rate of the evaporation gas to a suitable flow rate value according to the water inlet temperature of the cooling water through the dual-channel gas transmission component 1. Specifically, the dual-channel gas transmission component 1 includes a suction gas transmission pipeline 109 and a direct connection gas transmission pipeline 1010. A pipeline pump 102 for providing power for suction gas transmission is installed at the middle position of the suction gas transmission pipeline 109. Both ends of the suction gas transmission pipeline 109 and the direct connection gas transmission pipeline 1010 are fixedly connected with a gas transmission elbow 104 through a pipe joint 103. The lower ends of the gas transmission elbows 104 corresponding to the same end of the suction gas transmission pipeline 109 and the direct connection gas transmission pipeline 1010 are fixedly connected with a vertically arranged air outlet connection pipe 106 through a pipe joint 103. The bottom ends of the air outlet connection pipes 106 all penetrate through an end cover 107, and the end cover 107 coaxially seals the top of the discharge pipe 201 to connect the air outlet connection pipes 106 with the discharge pipe 201 through the end cover 107. The lower ends of the gas transmission elbows 104 corresponding to the other ends of the suction gas transmission pipeline 109 and the direct connection gas transmission pipeline 1010 are respectively fixedly connected with two interfaces of a three-way connection pipe 101 through a pipe joint 103. At the same time, the other interface of the three-way connection pipe 101 is fixedly connected with the intake connection pipe 302 through a pipe joint 103. The advantage of this setting is that when the water inlet temperature is high, the transmission flow rate of the evaporation gas can be adjusted to a suitable flow rate value by the single gas transmission method through the direct connection gas transmission pipeline 1010. At the same time, when the water inlet temperature is medium, the transmission flow rate of the evaporation gas can be adjusted to a suitable flow rate value by the single gas transmission method through the suction gas transmission pipeline 109. Moreover, when the water inlet temperature is low, the transmission flow rate of the evaporation gas can be adjusted to a suitable flow rate value by the combined gas transmission method of the direct connection gas transmission pipeline 1010 and the suction gas transmission pipeline 109, realizing the adaptive adjustment of the transmission flow rate of the evaporation gas according to the water inlet temperature in different seasons.

[0026] See Figures 1-2As shown in the figure, the following optimizations are carried out on the dual-channel gas transmission component 1, the condenser body 3, and the evaporator body 2 respectively. Specifically for the dual-channel gas transmission component 1, the pipe connectors 103 are all quick connectors, so that the pipes can be quickly combined and disassembled through the pipe connectors 103. At the same time, optionally, valves 105 for controlling the opening and closing and the opening degree are installed on the periphery of the air outlet connecting pipes 106. With such a setting, first, it is convenient to separately control the opening and closing of the corresponding air outlet connecting pipes 106 through the valves 105, and at the same time, the opening degree of the corresponding air outlet connecting pipes 106 can also be adjusted through the valves 105. Further optionally, the dual-channel gas transmission component 1 is also provided with two thermometer bodies 108, and the two thermometer bodies 108 are respectively used to detect the inlet water temperature and the outlet water temperature of the condenser body 3. Specifically, the upper and lower positions on one side of the periphery of the condenser body 3 are fixedly communicated with an outlet water connecting pipe 301 and an inlet water connecting pipe 303 respectively, and the two thermometer bodies 108 are respectively installed on the peripheries of the outlet water connecting pipe 301 and the inlet water connecting pipe 303. With such a setting, by observing the temperature measurement values of the thermometer bodies 108, the opening degrees of the valves 105 corresponding to the direct-connected gas transmission pipeline 1010 and the suction gas transmission pipeline 109 can be adjusted, further ensuring that the conveying flow rate of the evaporation gas can be adaptively adjusted to an appropriate flow rate value, and ensuring the full utilization of the heat absorption capacity of the cooling water.

[0027] Specifically for the condenser body 3 and the evaporator body 2, a discharge connecting pipe 304 for discharging the purified octafluoropropane finished product is fixedly communicated vertically at the bottom of the condenser body 3. With such a setting, it is convenient to discharge the purified octafluoropropane finished product smoothly outside the condenser body 3 through the discharge connecting pipe 304. Optionally, a liquid inlet pipe 202 for introducing the octafluoropropane finished product to be purified is fixedly communicated at the lower part of one side of the evaporator body 2, and a slag discharge pipe 203 for discharging the evaporation waste residue is fixedly communicated vertically at the bottom of the evaporator body 2, so as to input the octafluoropropane finished product to be purified into the evaporator for evaporation operation through the liquid inlet pipe 202, and at the same time, it is convenient to discharge the evaporation waste residue in the evaporator body 2 to the outside through the evaporator body 2.

[0028] With the above structure, during the process of filtering and purifying octafluoropropane finished products by evaporation and condensation, since a dual-channel gas transmission component 1 is provided between the evaporator body 2 and the condenser body 3, and the dual-channel gas transmission component 1 is respectively a direct-connection gas transmission pipeline 1010 and a suction gas transmission pipeline 109. Then, when the water inlet temperature is at a high level, such as in summer, the valve 105 of the air outlet connection pipe 106 corresponding to the suction gas transmission pipeline 109 is closed, and then the valve 105 of the air outlet connection pipe 106 corresponding to the direct-connection gas transmission pipeline 1010 is opened. Then, by the way of gas transmission through the direct-connection gas transmission pipeline 1010 alone, the transmission flow rate of the evaporation gas provided by the evaporator body 2 can be adaptively adjusted to an appropriate flow rate value. At the same time, when the water inlet temperature is at a medium level, such as in spring and autumn, the valve 105 of the air outlet connection pipe 106 corresponding to the direct-connection gas transmission pipeline 1010 is closed, and then the valve 105 of the air outlet connection pipe 106 corresponding to the suction gas transmission pipeline 109 is opened and the pipeline pump 102 is powered on through electrical connection with an external power supply cable. Then, by the way of gas transmission through the suction gas transmission pipeline 109 alone, the transmission flow rate of the evaporation gas can be adaptively adjusted to an appropriate flow rate value. Moreover, when the water inlet temperature is at a low level, such as in winter, the valve 105 of the air outlet connection pipe 106 corresponding to the direct-connection gas transmission pipeline 1010 is opened, and at the same time the valve 105 of the air outlet connection pipe 106 corresponding to the suction gas transmission pipeline 109 is opened and the pipeline pump 102 is powered on through electrical connection with an external power supply cable. Then, by the way of gas transmission through the direct-connection gas transmission pipeline 1010 and the suction gas transmission pipeline 109 together, the transmission flow rate of the evaporation gas can be adaptively adjusted to an appropriate flow rate value, realizing the adaptive adjustment of the transmission flow rate of the evaporation gas according to the water inlet temperature in different seasons, which is convenient for ensuring that the octafluoropropane finished products have good evaporation and condensation efficiency in different seasons. And because there are two temperature measuring instrument bodies 108 of the dual-channel gas transmission component 1, which are respectively installed on the water inlet connection pipe 303 and the water outlet connection pipe 301 of the condenser body 3. Then, by observing the temperature measurement values of the temperature measuring instrument bodies 108, the opening degrees of the valves 105 corresponding to the direct-connection gas transmission pipeline 1010 and the suction gas transmission pipeline 109 can be adjusted, further ensuring that the transmission flow rate of the evaporation gas can be adaptively adjusted to an appropriate flow rate value, and ensuring the full utilization of the heat absorption capacity of the cooling water.

[0029] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
