When the steam-water heat exchanger is in use, condensed water is generated inside and needs to be discharged. Usually, a steam trap is installed at the bottom of the steam-water heat exchanger for discharge treatment. And the existing steam trap is a device used to discharge condensed water installed on the steam-water heat exchanger. Before the device is installed and used, it is convenient for primary filtration and then cleaning, and then enters the internal filtration treatment again, reducing the number of times of disassembling and cleaning the inside of the hydrophobic device main body, and improving the convenience and treatment efficiency of filtration when the hydrophobic device is installed on the steam-water heat exchanger;

[0003] When the existing hydrophobic device is installed on the heat exchanger and used, and during the internal drainage treatment of the steam trap, it is filtered by the internal filter screen. As a result, it is not convenient to perform fine filtration on the steam trap previously. During long-term filtration treatment, it is easy for dirt to accumulate on the internal filter screen, and frequent cleaning and disassembly operations are inconvenient and cumbersome. Even the internal components may be damaged, reducing the use effect when installed on the steam-water heat exchanger, and affecting the convenience of filtration and the steam-water heat rate when the steam trap is installed on the steam-water heat exchanger. For this reason, the utility model proposes a steam-water heat exchanger efficiency-improving hydrophobic device. Summary of the Utility Model

A sealing ring 1014 is snap-fitted at the inner edge of the internal thread mounting hole 1011. An external thread placement ring 1012 rotates inside the internal thread mounting hole 1011. An internal hexagonal slot 1013 is opened at the end of the external thread placement ring 1012, which is convenient for a wrench to be clamped inside the internal hexagonal slot 1013 to drive the external thread placement ring 1012 to rotate and fix inside the internal thread mounting hole 1011 until the external thread placement ring 1012 rotates and presses against the surface of the sealing ring 1014 for sealing and fixing.

[0032] In order to facilitate the centralized adsorption and treatment of the iron chips generated after rusting inside the main steam trap 101 through the iron chip adsorption component, in this embodiment, preferably, the iron chip adsorption component includes an adsorption magnet 1015 placed inside the external thread placement ring 1012.

[0034] Working principle and usage process of the present utility model: For this kind of condensate drainage device that improves the efficiency of the steam-gas heat exchanger, before use, first install it at the connection port at the bottom of the steam-gas heat exchanger through the water inlet pipe 102, and then connect the water outlet pipe 103 to the external discharge pipe, so as to install the main body 100 of the condensate drainage device at the bottom of the steam-gas heat exchanger to improve the rate of condensate drainage;

[0035] Then, before the main body 100 of the condensate drainage device is fixedly installed and used, slide the pull rod 1024 inside the chute 1023 through the slider 1022. When the slider 1022 slides, it drives the arc-shaped filter screen 1021 to close at the inner bottom end of the arc-shaped filter screen 1021 until the end of the pull rod 1024 is closed inside the internal thread hole 1026. The wrench is engaged inside the internal hexagonal groove two 1027 to rotate the external thread fixing column 1025 to fixedly install the pull rod 1024, thereby fixing the arc-shaped filter screen 1021. When water enters through the water inlet pipe 102 during the installation of the main body 100 of the condensate drainage device on the heat exchanger, it is convenient to conduct primary fine filtration treatment through the arc-shaped filter screen 1021. When it enters the main condensate drainage valve 101 again, it is filtered by the filter ring inside the main condensate drainage valve 101. And during long-term filtration treatment, it is not easy to cause the rapid accumulation of dirt on the filter screen ring inside the main body 100 of the condensate drainage device, reducing the number of disassembly and cleaning operations inside the main body 100 of the condensate drainage device, and facilitating more effective dual filtration treatment, improving the convenience and treatment efficiency of filtration when the main body 100 of the condensate drainage device is installed on the steam-gas heat exchanger. When dirt accumulates on the surface of the arc-shaped filter screen 1021, the end of the water inlet pipe 102 can be disassembled. On the contrary, operate to pull the pull rod 1024 to pull the arc-shaped filter screen 1021 to the end of the water inlet pipe 102 for cleaning treatment, which is simpler and more convenient than cleaning the inside of the main condensate drainage valve 101;

[0036] Finally, before the main body 100 of the condensate drainage device is installed and used, place the adsorption magnet 1015 inside the external thread placement ring 1012, close the pressure ring 1016 inside the external thread placement ring 1012 and rotate the fixing screw 1017 for fixed installation, thereby fixing the adsorption magnet 1015 inside the external thread placement ring 1012. Then, the wrench is engaged inside the internal hexagonal groove one 1013 to rotate the external thread placement ring 1012 and fix it inside the internal thread installation hole 1011 and seal it with the sealing ring 1014. And when there are broken iron filings impacted by rust during the regular drainage treatment inside the main body 100 of the condensate drainage device, the adsorption magnet 1015 can adsorb the broken iron filings generated by internal rust into the internal storage of the external thread placement ring 1012, and it is convenient to remove the external thread placement ring 1012 during treatment to take out the broken iron filings, improving the convenience of removing broken iron filings inside the main body 100 of the condensate drainage device when it is installed on the steam-gas heat exchanger, with high-efficiency treatment, and the magnetic force of the adsorption magnet 1015 is effective and does not easily affect the operation of internal components.
