Description

Technical Field

[0001] This invention relates to the field of condensate recovery technology, specifically to a condensate recovery device for heating steam pipelines. Background Technology

[0002] In heating systems, during the process of transporting steam through steam pipelines, the steam will liquefy into condensate when it encounters the low-temperature pipeline. When the condensate accumulates at the lowest point of the pipeline, it can be discharged. By recycling the condensate, it can be sent back to the boiler for reuse. Moreover, the liquefied condensate has a high purity and high recycling value.

[0003] Prior art 1 (Chinese patent application number CN202510436965.3, published May 30, 2025) discloses a method and system for recovering condensate from steam pipelines. The steam pipeline condensate recovery system is connected to a drain pipe on the steam pipeline and includes an inlet mechanism, a collection mechanism, a heating mechanism, and a venting mechanism. The inlet mechanism is used to introduce condensate from the drain pipe; the collection mechanism is used to collect the condensate introduced by the inlet mechanism; the heating mechanism is used to heat the condensate collected by the collection mechanism into steam; and the venting mechanism is used to return the steam heated by the heating mechanism to the steam pipeline. The operating cost of this application is basically offset by the saved steam cost, resulting in extremely low cost. However, it solves the problem of the impact of condensate discharge on the safety and environmental protection of the production site, and has great practical value in actual production activities. Prior art 2 (Chinese patent application number CN202121318162.1, published May 30, 2025) discloses a method and system for recovering condensate from steam pipelines. The steam pipeline condensate recovery system is connected to a drain pipe on the steam pipeline and includes an inlet mechanism, a collection mechanism, a heating mechanism, and a venting mechanism. The inlet mechanism is used to introduce condensate from the drain pipe; the collection mechanism is used to collect the condensate introduced by the inlet mechanism; the heating mechanism is used to heat the condensate collected by the collection mechanism into steam; and the venting mechanism is used to return the steam heated by the heating mechanism to the steam pipeline. The operating cost of this application is basically offset by the saved steam cost, resulting in extremely low cost. However, it solves the problem of condensate discharge on the safety and environmental protection of the production site, and has great practical value in actual production activities. (Chinese Patent published on January 18, 2017) A condensate recovery device for power plant heating steam pipelines includes a main body. Both ends of the main body are fixedly connected to connecting discs. Several sets of screw holes are opened on the surface of both sets of connecting discs. A guide funnel is fixedly connected to the inner wall of one set of connecting discs. The main body is composed of two parts: a transport roller and a heat dissipation roller. The two ends of the main body are composed of transport rollers, and the middle part is the heat dissipation roller. A filtration mechanism and a cooling mechanism are installed inside the main body. This invention uses the heat dissipation roller to filter and purify the condensate, making the discharged condensate purer. Excessive impurities in the condensate can damage the water pump, and it also facilitates the subsequent recycling of the condensate. Through the heat dissipation roller and the cooling mechanism, after the condenser condenses the steam, the condensate, which still has a certain temperature, is cooled a second time, thus avoiding cavitation of the water pump due to excessively high water temperature.

[0004] Currently, when recovering condensate from steam pipes, the condensate inside the pipes easily adheres to pipe residue, causing the water to become turbid. Subsequent collection requires filtration. However, using traditional filter screens can easily lead to clogging over time, affecting the normal operation of the filtration process. Furthermore, cleaning the filter structure requires stopping condensate collection and suspending the use of the device, reducing its ease of use. Summary of the Invention

[0005] The purpose of this invention is to provide a condensate recovery device for heating steam pipelines, in order to solve the problems mentioned in the background art, where the condensate in the steam pipeline is easily covered with pipeline residue, resulting in turbidity. Subsequent collection requires filtration, and with traditional filter screens, the screens easily become clogged over time, affecting the normal operation of the filtration process. Furthermore, cleaning the filter structure requires stopping the collection of condensate.

[0021] The transmission block is set on the outside of the transmission shaft and between the transmission shaft to form a telescopic structure, and the transmission block and the transmission groove form an engaging structure.

[0022] The first spring is fixed to the right end of the transmission block to provide thrust to the transmission block;

[0023] The motor is connected to the drive shaft to control the rotation of the drive shaft.

[0024] To further optimize this technical solution, a hollow cylinder is fixed inside the filter cartridge, and the right end of the hollow cylinder penetrates through the surface of the filter cartridge. A magnetic rod is nested inside the hollow cylinder, and a connecting ring is fixed to the right end of the magnetic rod. A support frame is attached to the right side of the connecting ring. The support frame is fixed inside the collection box, and ball bearings are installed on the surface of the support frame.

[0025] To further optimize this technical solution, an installation guide mechanism is provided above the installation block to guide the installation of the installation block, and an installation component is rotatably installed above the installation block.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] (1) The collected condensate is separated by a partition plate. The condensate on the partition plate can enter the filter cylinder through the guide channel to complete the filtration and then enter the bottom of the collection box. It is then sent back to the boiler for use with the transfer pump, realizing the recycling of condensate. The filter cylinder adopts a rotary filter, which can avoid the accumulation of impurities and blockage of the filter surface, keep the filtration efficient, extend the service life of the filter cylinder, and when the filter cylinder is taken out for cleaning, the condensate can be collected above the partition plate for temporary storage without stopping the collection of condensate. After the filter cylinder is reinstalled, the water continues to be treated through the filter cylinder.

[0040] (2) The float can block the opening. When there is no condensate, it can prevent steam from entering the opening and avoid wasting steam heat. After the condensate accumulates, the float will be pushed up by buoyancy, and the water will be automatically discharged along the opening.

[0041] (3) The magnetic rod, in conjunction with the hollow cylinder, can attract the metal residue inside the filter cylinder, preventing it from adhering to the surface of the filter cylinder. The magnetic rod can then be pulled out from the hollow cylinder to remove the impurities, making it convenient to clean the inside of the filter cylinder.

[0042] (4) The condensate is guided and collected by the connection of the guide groove and the docking groove, so that it can smoothly enter the filter cartridge. After the filter cartridge is removed, the docking groove can be automatically closed by the action of the sealing block to stop the delivery of condensate, so that the condensate stays above the partition plate temporarily. After the filter cartridge is reinstalled, the condensate will continue to enter the filter cartridge.

[0043] (5) The drive shaft and the mounting head are connected to the drive block and the drive groove to provide rotational power to the filter cartridge. The drive shaft and the mounting head are connected by a plug-in type, which does not affect the subsequent disassembly of the filter cartridge. At the same time, even if the drive block and the drive groove are not accurately connected, the drive block can compress the first spring, and the drive block will automatically pop out when it is connected to the drive groove, making the installation more convenient.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example 1: The present invention provides the following technical solution: a condensate recovery device for heating steam pipelines, such as... Figure 1-2 and Figure 4-8 As shown, the system includes a collection tank 1 for recovering condensate. A transfer pump 2 is installed on the outside of the collection tank 1, and a transmission pipeline 3 is connected to the outside of the transfer pump 2 to transport the collected condensate to the boiler. An inlet 4 is provided on the top of the collection tank 1, and a pipe connection mechanism is connected above the inlet 4. The inlet 4 is connected to the condensate discharge position of the steam pipeline through the pipe connection mechanism. A partition plate 15 is provided inside the collection tank 1, and a filter cylinder 13 is provided below the partition plate 15. An installation head 17 is installed on both the left and right ends of the filter cylinder 13. The left end of the filter cylinder 13 is rotated through the installation head 17. A mounting block 14 is attached, and the mounting block 14 and the collection box 1 are detachably connected. A rotary drive mechanism is connected to the right side of the filter cylinder 13, and a discharge pipe 27 is provided inside the filter cylinder 13. The discharge pipe 27 is fixed to the surface of the mounting block 14. A guide groove 28 is connected to the left end of the discharge pipe 27, and a liquid collection mechanism is provided above the guide groove 28 to collect the liquid on the partition plate 15 into the guide groove 28. The inlet 4 is evenly distributed above the collection box 1, and a one-way valve 5 is installed inside the inlet 4. The one-way valve 5 is directed from the outside of the collection box 1 to the inside of the collection box 1.

[0057] During use, inlet 4 and the condensate drain position of the steam pipe can be connected via a pipe connection mechanism, such as... Figure 3As shown, condensate enters the collection tank 1 through inlet 4, is separated by partition plate 15, and then enters filter cylinder 13 to filter impurities in the condensate. The filtered condensate enters the bottom of the collection tank 1 and is transported to the boiler for recycling by delivery pump 2 and transmission pipeline 3. A pressure regulating valve 16 is installed on the side of the collection tank 1 to regulate the pressure in the collection tank 1 and keep it stable.

[0058] Example 2: Based on Example 1, as follows Figure 3 and Figure 9-10 As shown, the pipe connection mechanism further discloses a connecting pipe 6, a connector 7, a mounting shell 8, and an automatic control mechanism. The connecting pipe 6 is installed above the inlet 4. The connector 7 is installed at the end of the connecting pipe 6 to connect the connecting pipe 6 and the condensate drain pipe. The mounting shell 8 is located below the connector 7. The automatic control mechanism is located inside the mounting shell 8 and controls the drainage. The automatic control mechanism includes a baffle 9, a float 10, a port 11, and a guide rod 12. The baffle 9 is fixed inside the mounting shell 8. The float 10 is located above the baffle 9. The port 11 is opened in the middle of the baffle 9, and the float 10 is located above the port 11 to block the port 11. The guide rod 12... 2. Fixed below the float 10, and the guide rod 12 and the mounting shell 8 form an up-and-down sliding structure to guide the movement of the float 10. The rotary drive mechanism includes a drive shaft 18, a drive groove 19, a drive block 20, a first spring 21 and a motor 22. The drive shaft 18 is rotatably installed inside the collection box 1. The drive groove 19 is opened on the right side of the mounting head 17. The drive block 20 is set on the outside of the drive shaft 18 and forms a telescopic structure between the drive shaft 18 and the drive groove 19. The drive block 20 and the drive groove 19 form an engaging structure. The first spring 21 is fixed at the right end of the drive block 20 to provide thrust to the drive block 20. The motor 22 is connected to the drive shaft 18 to control the rotation of the drive shaft 18.

[0059] After connecting connector 7 and condensate drain pipe, the opening 11 inside the mounting housing 8 is closed by default. Figure 3 As shown, when condensate enters the baffle 9, the accumulated water pushes the float 10 upwards through buoyancy, opening the opening 11 and allowing the water to pass through smoothly. As the water enters the filter cylinder 13, it is filtered by the rotation of the filter cylinder 13. Figure 8-10As shown, the transmission shaft 18 is driven to rotate by the motor 22. The transmission shaft 18, through the connection of the transmission block 20 and the transmission groove 19, drives the filter cartridge 13 to rotate on the right side of the mounting block 14. When installing the filter cartridge 13, if the transmission groove 19 and the transmission block 20 are not properly aligned, the mounting head 17 presses against the transmission block 20, compressing the first spring 21. When the transmission shaft 18 drives the transmission block 20 to rotate until it is aligned with the transmission groove 19, the transmission block 20 extends under the action of the first spring 21. Figure 10 As shown, the drive shaft 18 stably drives the mounting head 17 to rotate.

[0060] Example 3: Based on Example 1, as follows Figure 6-9 As shown, a hollow cylinder 23 is fixed inside the filter cartridge 13, and the right end of the hollow cylinder 23 penetrates the surface of the filter cartridge 13. A magnetic rod 24 is nested inside the hollow cylinder 23, and a connecting ring 25 is fixed to the right end of the magnetic rod 24. A support frame 26 is attached to the right side of the connecting ring 25. The support frame 26 is fixed inside the collection box 1, and ball bearings are installed on the surface of the support frame 26. An installation guide mechanism is provided above the mounting block 14 to guide the installation of the mounting block 14. An installation component 37 is rotatably installed above the mounting block 14. An installation groove 38 is opened on the surface of the collection box 1, which forms a threaded connection with the installation component 37. The installation guide mechanism includes a slide 35 and a positioning block 36. The slide 35 is opened on the upper surface of the mounting block 14, and the side view cross section of the slide 35 has an inverted "T" shaped structure design. The positioning block 36 is fixed below the partition plate 15, and a horizontal sliding structure is formed between the positioning block 36 and the slide 35. The body collection mechanism includes a docking groove 30, a sealing block 31, a control head 32, a second spring 33, and an opening mechanism. The docking groove 30 is located inside the partition plate 15 and above the guide groove 28. The sealing block 31 is located above the docking groove 30 and blocks its opening. The control head 32 is fixed below the sealing block 31 and forms a sliding structure with the partition plate 15. The second spring 33 is located outside the control head 32 and provides downward thrust to the control head 32. The opening mechanism is located below the control head 32 and controls the opening of the docking groove 30. The opening mechanism includes a top block 29 and an inclined groove 34. The top block 29 is fixed above the guide groove 28 and has an inclined structure on its right side. The top block 29 and the control head 32 are in contact to provide upward thrust to the control head 32. The inclined groove 34 is located on the right side of the guide groove 28 and is located on the right side of the top block 29.

[0061] The magnetic rod 24 can adsorb impurities inside the filter cartridge 13 onto the surface of the hollow cylinder 23. The magnetic rod 24 can then be removed via the connecting ring 25. Figure 6As shown, this allows impurities to fall off, facilitating cleaning of the inside of the filter cartridge 13. After the mounting block 14 is installed, the guide groove 28 and the docking groove 30 are opposite each other. The top block 29 presses the control head 32, causing it to move the sealing block 31 upward, opening the docking groove 30. The condensate on the partition plate 15 falls into the guide groove 28 through the docking groove 30, and then enters the inside of the filter cartridge 13 through the discharge pipe 27. When the mounting block 14 is disassembled, the connection between the mounting part 37 and the mounting groove 38 can be released by rotation, and the mounting block 14 can be pulled out of the collection box 1. After the mounting block 14 is pulled out, the pressure of the top block 29 on the control head 32 disappears, and the second spring 33 pushes the control head 32 downward, causing the sealing block 31 to move and seal the docking groove 30, so that the condensate is blocked above the partition plate 15. When the mounting block 14 is reinstalled, the condensate will automatically continue to be discharged.
