Description
Technical Field
[0001] This invention relates to the field of steam recovery and utilization technology, specifically to a steam recovery and utilization device and its working method for a boiler turbine. Background Technology
[0002] A steam turbine, also known as a steam turbine engine, is a rotary steam power unit. In the current technology, most of the steam used by steam turbines is directly discharged through pipelines, which is very wasteful. In order to make full use of steam, most steam recovery and utilization devices are used to liquefy and collect the steam.
[0003] However, existing steam recovery devices can only liquefy steam into water for storage. Since the steam contains impurities during discharge, these impurities are not filtered out, and the liquefied steam also contains impurities and cannot be used directly. A secondary filtration process is still required, which is cumbersome. Therefore, it is necessary to design a boiler turbine steam recovery and utilization device and its operating method to solve the problems of steam waste during discharge and impurities during recovery in existing technologies. Summary of the Invention
[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a boiler turbine steam recovery and utilization device and its working method.
[0005] The technical solution adopted by the present invention to solve its technical problem is: a boiler turbine steam recovery and utilization device, including a recovery box, a cooling mechanism sleeved on the top of the recovery box, a connecting pipe provided inside the cooling mechanism, the connecting pipe passing through the recovery box and fixedly connected to the recovery box, a water pump fixedly connected to the left side of the recovery box, the water pump being connected to the cooling mechanism, a power mechanism connected to the right side of the cooling mechanism, a filter mechanism fixedly connected inside the recovery box, the filter mechanism being connected to the connecting pipe, and grooves being provided through the left and right sides of the recovery box.
[0006] Preferably, the cooling mechanism includes multiple annular water pipes, which are fixedly connected to the recycling tank. The multiple annular water pipes are connected through a first water supply pipe. A hollow tube is provided through the middle of the first water supply pipe, and the first water supply pipe is fixedly connected to the hollow tube. The left end of the first water supply pipe is connected to a water pump.
[0007] Preferably, the power mechanism includes a hollow disc, a first rotating shaft is rotatably connected inside the hollow disc, an impeller is disposed inside the hollow disc, the impeller is fixedly connected to the first rotating shaft, one end of the hollow disc is connected to a water inlet pipe, and the other end of the hollow disc is connected to a first water delivery pipe.
[0008] Preferably, the filtration mechanism includes a mounting box, which is connected to a connecting pipe. A second rotating shaft is rotatably connected to the inner walls of both sides of the inner cavity of the mounting box. A first reciprocating screw is fixedly connected between the two second rotating shafts. A sealing block is threaded onto the first reciprocating screw. The sealing block is slidably connected to the mounting box. A filter plate is provided below the mounting box. Both sides of the filter plate are connected to a recycling box via connecting blocks.
[0009] Preferably, a second reciprocating screw is provided above the filter plate, and a scraper is threaded onto the second reciprocating screw. The left and right sides of the scraper are respectively connected to the mounting box through two connecting hoses. A fourth rotating shaft is fixedly connected to both sides of the second reciprocating screw. The fourth rotating shaft is rotatably connected to the recycling box. The fourth rotating shaft located at the right end of the second reciprocating screw extends to the outside of the recycling box. Two third bevel gears are fixedly connected to the fourth rotating shaft located at the right end of the second reciprocating screw. A second bevel gear is fixedly connected to the second rotating shaft located at the right end of the first reciprocating screw. A third rotating shaft is provided through the mounting box and is rotatably connected to the mounting box. A first bevel gear is fixedly connected to both ends of the third rotating shaft. The two first bevel gears mesh with the second bevel gear and the inner third bevel gear, respectively. A fourth bevel gear is fixedly connected to the first rotating shaft and meshes with the outer third bevel gear.
[0010] Preferably, a piston plate is slidably connected inside the recycling bin, and an alarm mechanism is provided below the piston plate.
[0011] A method for operating a boiler turbine steam recovery and utilization device includes the following steps:
[0012] 1) When steam needs to be collected, connect the steam outlet to the connecting pipe through an external pipeline;
[0013] 2) Start the water pump. The water pump will draw water from the external water tank into the inlet pipe, the ring water pipe, the first water delivery pipe, and the hollow plate. Finally, the water will return to the external water tank through the water pump, forming a dynamic balance.
[0014] 3) The steam inside the connecting pipe will be cooled and liquefied and flow into the installation box. The liquefied steam entering the installation box will be transported to the filter plate through the connecting hose, where it will be filtered to intercept impurities in the liquefied steam and obtain clean liquefied steam.
[0015] 4) After the water source is connected to the water inlet pipe, the water source will enter the hollow disc, thereby driving the impeller to rotate. The impeller drives the first rotating shaft to rotate, thereby causing the second reciprocating screw to move the scraper left and right. The first reciprocating screw drives the sealing block to move.
[0016] 5) As the liquefied vapor in the recycling bin increases, the total weight of the liquefied vapor also increases. This will cause the piston plate to move downwards due to gravity, triggering the alarm mechanism to sound and serving as a reminder, thus facilitating the timely transfer of the collected liquefied vapor.
[0017] The present invention has the following beneficial effects:
[0018] The present invention relates to a boiler turbine steam recovery and utilization device and its working method.
[0019] 1. Steam can be introduced into the installation box through the connecting pipe. Under the action of the cooling mechanism, the steam can be effectively liquefied into water. The steam from the liquefied water source will also be filtered by the filter plate, so that clean liquefied steam can be obtained directly without secondary treatment. With the help of the water flow, the scraper can continuously clean the impurities on the filter plate and discharge the impurities into the recovery box, thus avoiding the phenomenon of impurities clogging the filter plate.
[0020] 2. Due to the combined use of the scraper and the sealing block, when the scraper moves to a certain position to the left or right, the sealing block blocks the connecting hose on the left or right side, preventing the liquefied vapor from being discharged from the left or right side. Thus, during the filtration process, the scraper effectively prevents the liquefied vapor from flowing out of the groove.
[0021] 3. By setting up springs, slide bars, and latex moving balls, when a certain amount of liquefied vapor is collected inside the recycling bin, the latex moving balls are squeezed by the pressure plate, causing them to make a sound, thus serving as a reminder and facilitating timely disposal.

Detailed Implementation
[0028] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0029] Example 1:
[0030] like Figure 1-5 As shown, a boiler turbine steam recovery and utilization device includes a recovery box 11. A cooling mechanism is fitted on the top of the recovery box 11. A connecting pipe 7 is installed inside the cooling mechanism, which passes through the recovery box 11 and is fixedly connected to it. A water pump 3 is fixedly connected to the left side of the recovery box 11 and is connected to the cooling mechanism. A power mechanism is connected to the right side of the cooling mechanism. A filter mechanism is fixedly connected inside the recovery box 11 and is connected to the connecting pipe 7. Grooves are provided through both the left and right sides of the recovery box 11.
[0031] When steam needs to be collected, the steam outlet can be connected to the connecting pipe 7 through an external pipeline.
[0032] The cooling mechanism includes multiple annular water pipes 5, which are fixedly connected to the recovery tank 11. The multiple annular water pipes 5 are connected by a first water supply pipe 6. A hollow pipe 8 is installed through the middle of the first water supply pipe 6. The first water supply pipe 6 and the hollow pipe 8 are fixedly connected. The left end of the first water supply pipe 6 is connected to the water pump 3. Then, the inlet pipe 10 and the outlet of the water pump 3 are connected to the pipe of the external water tank. The water pump 3 is started, and the water pump 3 will draw water from the external water tank into the inlet pipe 10, the annular water pipes 5, the first water supply pipe 6, and the hollow plate 9. Finally, the water returns to the external water tank through the water pump 3, forming a dynamic balance. Since the connecting pipe 7 is located inside the annular water pipes 5, the steam entering the connecting pipe 7 will be cooled and liquefied and flow into the installation box 15. The liquefied steam entering the installation box 15 will be transported to the filter plate 16 through the connecting hose 12, and thus filtered by the filter plate 16 to intercept impurities in the liquefied steam, so that clean liquefied steam is obtained.
[0033] The power mechanism includes a hollow disc 9, with a first rotating shaft 26 rotatably connected inside. An impeller 20 is disposed inside the hollow disc 9 and fixedly connected to the first rotating shaft 26. One end of the hollow disc 9 is connected to the water inlet pipe 10, and the other end is connected to the first water supply pipe 6. The filtration mechanism includes a mounting box 15, which is connected to a connecting pipe 7. Second rotating shafts 27 are rotatably connected to the inner walls of both sides of the inner cavity of the mounting box 15. A first reciprocating screw 14 is fixedly connected between the two second rotating shafts 27. A sealing block 13 is threaded onto the first reciprocating screw 14, and the sealing block 13 is connected to the mounting box 15. 5. A sliding connection is provided. A filter plate 16 is installed below the mounting box 15. Both sides of the filter plate 16 are connected to the recycling box 11 via connecting blocks. A second reciprocating screw 17 is installed above the filter plate 16. A scraper 18 is threaded onto the second reciprocating screw 17. The left and right sides of the scraper 18 are connected to the mounting box 15 via two connecting hoses 12. A fourth rotating shaft 32 is fixedly connected to both sides of the second reciprocating screw 17. The fourth rotating shaft 32 is rotatably connected to the recycling box 11. The fourth rotating shaft 32 located at the right end of the second reciprocating screw 17 extends to the outside of the recycling box 11. Two third bevel gears 31 are fixedly connected to the first reciprocating screw 14. A second bevel gear 29 is fixedly connected to the second rotating shaft 27 located at the right end of the first reciprocating screw 14. A third rotating shaft 30 is provided through the mounting box 15 and is rotatably connected to the mounting box 15. First bevel gears 28 are fixedly connected to both ends of the third rotating shaft 30. The two first bevel gears 28 mesh with the second bevel gear 29 and the inner third bevel gear 31, respectively. A fourth bevel gear 33 is fixedly connected to the first rotating shaft 26 and meshes with the outer third bevel gear 31. The water inlet pipe 10 is used to supply water. Afterwards, water enters the hollow disc 9, which drives the impeller 20 to rotate. The impeller 20 drives the first rotating shaft 26 to rotate. The first rotating shaft 26 drives the fourth rotating shaft 32 to rotate through the fourth bevel gear 33 and the third bevel gear 31. The fourth rotating shaft 32 drives the second reciprocating screw 17 to rotate. The second reciprocating screw 17 causes the scraper 18 to move left and right. The fourth rotating shaft 32 also drives the second rotating shaft 27 to rotate through the third bevel gear 31, the third rotating shaft 30, the first bevel gear 28, and the second bevel gear 29. The second rotating shaft 27 drives the first reciprocating screw 14 to rotate. The first reciprocating screw 14 drives the sealing block 13 to move.
[0034] Since the sealing block 13 rotates synchronously with the scraper 18, when the scraper 18 drives the connecting hose 12 to move to the left, the sealing plate will also move to the left. When the scraper 18 moves to a certain position to the left, the sealing plate will block the connecting hose 12 on the left side of the mounting box 15. In this way, the connecting hose 12 on the left side of the scraper 18 will not discharge liquefied vapor. Thus, while the scraper 18 discharges impurities from the filter plate 16, there will be no liquefied vapor discharged from there, avoiding the waste of liquefied vapor.
[0035] Furthermore, storage boxes 4 are fixedly connected to both sides of the recycling bin 11, which can be used to collect impurities.
[0036] Example 2:
[0037] like Figure 1-5 As shown, while other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: a piston plate 19 is slidably connected inside the recycling bin 11, and an alarm mechanism is provided below the piston plate 19. The alarm mechanism includes a sliding sleeve, which passes through the bottom end of the recycling bin 11 and is fixedly connected to the recycling bin 11. A sliding rod 22 is slidably connected inside the sliding sleeve, and the top end of the sliding rod 22 is fixedly connected to the piston plate 19. A spring 21 is sleeved on the sliding rod 22, and both ends of the spring 21 are fixedly connected to the recycling bin 11 and the piston plate 19, respectively. A base 1 is provided below the sliding rod 22, and the base 1 is fixedly connected to the recycling bin 11 through multiple support columns 2. A hollow tube 23 is fixedly connected to the top end of the base 1, and a latex sports ball 25 is provided inside the hollow tube 23. A pressure plate 24 is slidably connected inside the hollow tube 23, and the pressure plate 24 is fixedly connected to the bottom end of the sliding rod 22.
[0038] As the liquefied vapor in the recycling bin 11 increases, the total weight of the liquefied vapor also increases. As a result, the piston plate 19 will continuously squeeze the spring 21 downwards under the action of gravity. The downward movement of the piston plate 19 will drive the pressure plate 24 downwards. When the pressure plate 24 moves to a certain position, it will squeeze the latex ball 25, causing the latex ball 25 to make a sound, which serves as a reminder and facilitates the timely transfer of the collected liquefied vapor.
[0039] A drain pipe with a valve is installed through the bottom of the recycling bin 11, and the drain pipe is fixedly connected to the recycling bin 11.
