[0015] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0016] This utility model provides a propylene pressure vessel pressurization device, such as... Figure 1-4 As shown, the propylene pressure vessel pressurization device includes: a booster pump 1 for pumping liquid propylene, with a connecting pipe 2 connected to the discharge end of the booster pump 1; a vaporizer 3 mounted on one side of the booster pump 1 for vaporizing the liquid propylene, the vaporizer 3 being connected to one end of the connecting pipe 2, and a conveying pipe 4 connected to the vaporizer 3 for conveying the vaporized propylene into the propylene pressure vessel; and a filtration mechanism mounted on the booster pump 1 for filtering and removing impurities from the liquid propylene.

[0017] In this embodiment, a SIMATIC S7-1500 controller is installed on one side of the device. The controller can control the entire device. The working principle of the controller is existing technology and will not be described in detail here. When propylene is stored in the propylene pressure vessel, the controller starts the booster pump 1 to pump the liquid propylene. The booster pump 1 compresses the liquid propylene, significantly increasing its pressure to the target value. The high-pressure liquid propylene is transported to the vaporizer 3 through the connecting pipe 2. After entering the vaporizer 3, the liquid propylene absorbs heat and changes phase to high-pressure gaseous propylene. The high-pressure gaseous propylene is transported to the propylene pressure vessel through the conveying pipe 4 and the pressure regulating valve 15. When the booster pump 1 pumps the liquid propylene, the filtration mechanism filters and removes impurities from the liquid propylene, effectively preventing impurities from entering the booster pump 1. This reduces scratches and wear on the pump plunger seal, lowers the risk of seal failure, and thus reduces the overall failure rate, improving the stability and reliability of the booster device.

[0018] In a further preferred embodiment of this utility model, the filtration mechanism includes: a filter box 5 mounted on one side of the booster pump 1; a filter screen 6 mounted inside the filter box 5, the filter screen 6 being used to filter liquid propylene; a placement pipe 7 fixedly mounted on the filter box 5, the placement pipe 7 being connected to the feed end of the booster pump 1; a discharge mechanism mounted on the filter box 5, the discharge mechanism being used to discharge impurities filtered on the filter screen 6; and a rinsing mechanism disposed on the filter box 5, the rinsing mechanism being used to rinse the impurities filtered on the filter screen 6.

[0019] In this embodiment, when liquid propylene enters the filter box 5, the filter screen 6 can filter the liquid propylene, intercepting impurities and effectively preventing impurities from entering the booster pump 1. This reduces scratches and wear on the pump's plunger seal, lowers the risk of seal failure, and consequently reduces the overall failure rate, improving the stability and reliability of the booster device. When it is necessary to clean the impurities filtered on the filter screen 6, the controller starts the unloading mechanism to rotate the filter screen 6 and unload the impurities filtered on the filter screen 6. At the same time, the flushing mechanism is started to flush the impurities filtered on the filter screen 6, further cleaning the residual impurities on the filter screen 6 and ensuring the unobstructed flow and filtration performance of the filter screen 6.

[0020] In a further preferred embodiment of the present invention, the unloading mechanism includes: a servo motor 8 fixedly installed on one side of the outer wall of the filter box 5; two mounting shafts 9 symmetrically rotatably installed on the filter box 5, the two mounting shafts 9 being fixedly connected to both sides of the filter screen 6 respectively, and the output shaft of the servo motor 8 being connected to one end of one of the mounting shafts 9 through a coupling.

[0021] In this embodiment, when using the unloading mechanism, the servo motor 8 is started by the controller. The rotation of the output shaft of the servo motor 8 is transmitted to the mounting shaft 9 connected to it through the coupling, thereby driving the entire filter screen 6 to rotate around the two mounting shafts 9 in reverse, and unloading the impurities filtered on the filter screen 6.

[0022] In a further preferred embodiment of the present invention, the rinsing mechanism includes: a cleaning pipe 10 fixedly installed on the inner wall of the top of the filter box 5, the cleaning pipe 10 being provided with a plurality of cleaning nozzles 11; and a vertical pipe 12 fixedly installed on the filter box 5, the vertical pipe 12 being connected to the cleaning pipe 10.

[0023] In this embodiment, when rinsing the filter screen 6, the vertical pipe 12 is connected to the corresponding water pump outlet. Pressurized water is sprayed onto the filter screen 6 through multiple cleaning nozzles 11 on the cleaning pipe 10, thereby rinsing the filter screen 6. During the rinsing process, the servo motor 8 can be started to drive the filter screen 6 to rotate continuously, so that both sides of the filter screen 6 can be thoroughly rinsed, improving the rinsing effect of the filter screen 6.

[0024] In a further preferred embodiment of the present invention, the filter box 5 is provided with a feed pipe 13, which is used to connect with a storage tank for storing liquid propylene, and the filter box 5 is provided with a drain pipe 14, which is used to discharge the wastewater used for cleaning the filter screen 6.

[0025] In this embodiment, the feed pipe 13 is connected to the storage tank for storing liquid propylene. When the device is running, liquid propylene flows smoothly from the storage tank into the filter box 5 through the feed pipe 13, providing raw materials for subsequent filtration operations. When rinsing the filter screen 6, the control valve on the drain pipe 14 is opened to discharge the wastewater used for cleaning the filter screen 6 in a timely manner through the drain pipe 14, so as to avoid the accumulation of wastewater in the filter box 5 and affect the normal operation of the device. Before the next use, the filter box 5 needs to be dried before use. A control valve is installed on the vertical pipe 12. When not rinsing, the control valve on the vertical pipe 12 needs to be closed.

[0026] In a further preferred embodiment of this utility model, a pressure regulating valve 15 is provided on the conveying pipe 4.

[0027] In this embodiment, the conveying pipe 4 conveys the high-pressure gaseous propylene, which has been vaporized by the vaporizer 3, to the propylene pressure vessel. The pressure regulating valve 15 can regulate and control the pressure of the high-pressure gaseous propylene passing through the conveying pipe 4. When the high-pressure gaseous propylene flows in the conveying pipe 4, the pressure regulating valve 15 can precisely adjust the gas pressure according to actual needs to make it reach the pressure value that meets the storage requirements of the propylene pressure vessel before entering the propylene pressure vessel.

[0028] In a further preferred embodiment of this utility model, the vaporizer 3 is provided with an outlet pipe, the outlet pipe is connected to the delivery pipe 4, and a temperature sensor is installed on the outlet pipe.

[0029] In this embodiment, a Pt100 temperature sensor is used to conveniently monitor the temperature of the discharged gaseous propylene, ensuring that the outlet gaseous propylene is in an appropriate superheated state and preventing liquid propylene from being carried into the downstream pipeline.

[0030] In summary, compared with related technologies, this device can perform pressurization operations and filter and remove impurities from liquid propylene, effectively preventing impurities from entering the booster pump 1. This reduces scratches and wear on the pump's plunger seal, lowers the risk of seal failure, and consequently reduces the overall failure rate, improving the stability and reliability of the booster device.

[0031] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
