Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically to a condenser for the Rankine cycle. Background Technology

[0002] In traditional Rankine cycle condensers, over time, a scale-like exchange substance often accumulates inside the condenser near the steam source. In practice, this exchange substance is treated by replacing and cleaning the condenser. However, this method is troublesome to clean and requires disassembly, which increases the difficulty of the work.

[0003] Therefore, we propose a condenser that can be easily cleaned in the Rankine cycle. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a condenser for the Rankine cycle to facilitate the cleaning of deposits within the condenser.

[0005] In a first aspect, this utility model provides a condenser for a Rankine cycle, comprising: a plate heat exchanger, a heat transfer main pipe, and a steam pipe component; the heat transfer main pipe is installed at one end of the plate heat exchanger, and the other end of the heat transfer main pipe is connected to one end of the steam pipe component; the steam pipe component includes a vent pipe and a spiral guide shaft; the spiral guide shaft is rotatably installed inside the vent pipe; the vent pipe is connected to an external steam source; the vent pipe is further provided with a titanium alloy pipe wall layer; the spiral guide shaft is provided with an outer scraping wall layer, the outer scraping wall layer being close to the titanium alloy pipe wall layer.

[0006] Furthermore, the steam pipe fitting also includes mounting sleeves; two mounting sleeves are provided, respectively located at both ends of the vent pipe, wherein both ends of the spiral guide shaft are rotatably connected to the mounting sleeves via bearings. In practical applications, the purpose of this design is to facilitate the rotation of the spiral guide shaft; thus, driven by the steam source, the spiral guide shaft rotates, effectively achieving efficient rotation and scraping the vent pipe, effectively reducing dirt accumulation and improving cleanliness.

[0007] Furthermore, it also includes a heat dissipation guide plate, which is installed on the steam pipe and located on the vent pipe. In practical applications, the purpose of this design is to improve heat dissipation and increase heat dissipation efficiency.

[0008] Furthermore, it also includes a cleaning assembly installed at the main heat transfer pipe. The cleaning assembly includes an on / off valve installed on the main heat transfer pipe, close to the plate heat exchanger. In practical applications, the purpose of this design is to enhance the cleaning effect. The on / off valve design serves two purposes: firstly, to improve ventilation, and secondly, to prevent cleaning liquids from flowing into the plate heat exchanger during the cleaning process. This allows for effective control.

[0009] Furthermore, the heat transfer main pipe is provided with two side cleaning ports, which are arranged opposite to each other. The cleaning assembly also includes a cleaning water pump, one end of which is connected to one of the side cleaning ports. In practical applications, the purpose of this design is to enhance the cleaning effect. In practical applications, the side cleaning port design, combined with the cleaning water pump, achieves water pressure rinsing. The aforementioned cleaning water pump is a variable frequency pump, thus enabling diverse cleaning effects. In this way, by changing the water flow impact, thorough cleaning is achieved.

[0010] Furthermore, the cleaning assembly also includes a sealing cover, which is detachably installed on the side cleaning port. In practical applications, this design has two sealing covers. During daily use, both sealing covers are sealed and installed on the side cleaning port. When cleaning is required, one of the side cleaning ports is connected to the cleaning water pump, allowing water pressure to rush into the vent pipe. Then, the other sealing cover is opened, and the cleaning water pump is turned off. This allows the dirt and liquid in the cleaned vent pipe to flow out from the other side cleaning port.

[0011] As can be seen from the above technical solution, the beneficial effects of the condenser for the Rankine cycle provided by this utility model are as follows:

[0012] (1) In practical application, the plate heat exchanger, heat transfer main pipe and steam pipe flow element used in this design constitute the condenser assembly in the Rankine cycle, so that the condensation effect can be achieved.

[0013] (2) Furthermore, the steam pipe fittings used achieve effective rotation of the spiral guide shaft through steam flow. During its rotation, since the titanium alloy pipe wall layer provided by the vent pipe is similar to the outer scraping wall layer provided by the spiral guide shaft, a swirl scraping effect can be achieved, effectively cleaning the inner wall of the vent pipe.

[0014] (3) At the same time, the titanium alloy tube wall material design can effectively reduce the deposition of deposits. Attached Figure Description

In practical applications, the plate heat exchanger 1, the main heat transfer pipe 2, and the steam pipe component 3 used in this design constitute the condenser assembly in the Rankine cycle, thus achieving a condensation effect. Furthermore, the steam pipe component 3 enables the effective rotation of the spiral guide shaft 32 through the steam flow. During its rotation, the titanium alloy pipe wall layer 311 of the vent pipe 31 is close to the outer scraping wall layer 321 of the spiral guide shaft 32, achieving a scraping effect and effectively cleaning the inner wall of the vent pipe 31. At the same time, the material design of the titanium alloy pipe wall layer 311 effectively reduces the deposition of deposits.

[0025] In this embodiment, the steam pipe component 3 further includes a mounting sleeve 33; the mounting sleeve 33 has two locations, respectively located at both ends of the vent pipe 31, wherein both ends of the spiral guide shaft 32 are rotatably connected to the mounting sleeve 33 via bearings. In practical applications, the purpose of this design is to facilitate the rotation of the spiral guide shaft 32; thus, driven by the steam source, the spiral guide shaft 32 rotates, effectively achieving efficient rotation and scraping the vent pipe 31, effectively reducing dirt accumulation and improving cleanliness.

[0026] In this embodiment, a heat dissipation guide plate 4 is also included. The heat dissipation guide plate 4 is installed on the steam pipe flow element 3 and located on the vent pipe 31. In practical applications, the purpose of this design is to improve the heat dissipation effect and increase heat dissipation.

The cleaning component 5 includes an on / off valve 51, which is installed on the heat transfer main pipe 2 and close to the plate heat exchanger 1. In practical applications, the purpose of this design is to enhance the cleaning effect. The on / off valve 51 is designed to enhance ventilation and also to prevent cleaning liquids from flowing into the plate heat exchanger 1 during the cleaning process. This allows for effective control.
