Description

Technical Field

[0001] The utility model relates to the technical field of temperature and pressure reducing devices, in particular to a condensed water recycling device of a temperature and pressure reducing device. Background Art

[0002] A desuperheater and pressure reducer is a device that reduces high-temperature and high-pressure steam to low-pressure and low-temperature steam that can be used by customers. It can be divided into the following two categories according to whether the desuperheating and pressure reduction are integrated: an integrated desuperheater and pressure reducer, where desuperheating and pressure reduction are performed in the same desuperheater and pressure reducing valve; a split desuperheater and pressure reducer, where desuperheating and pressure reduction are performed separately, and pressure reduction uses a separate pressure reducing valve. The split desuperheater and pressure reducer has the advantages of high control accuracy, stable operation, sensitive adjustment, and can effectively eliminate the influence of static errors. The steam in the desuperheater and pressure reducer is usually recycled when not in use, and condensed water is produced and heat energy is recovered to achieve the recycling of heat energy and water resources.

[0003] The utility model patent with patent announcement number CN206235178U discloses a steam condensate recycling device, including a condensate collection tank, a jet pump, an ejector and a process water pool; a condensate inlet for collecting steam condensate, a low-pressure steam outlet and an emptying port arranged at the bottom are arranged on the condensate collection tank, an emptying valve is installed on the emptying port, and a switch valve is installed on the condensate inlet; the ejector is a Venturi ejector, and the ejector is provided with a liquid inlet, a gas inlet and a liquid outlet; the inlet of the ejector pump is connected to the process water pool, the outlet of the ejector pump is connected to the liquid inlet of the ejector, and the gas inlet of the ejector is connected to the low-pressure steam outlet of the condensate collection tank. The utility model uses the negative pressure generated by water passing through the ejector as a power source to make the steam condensate form low-pressure steam, and then sucks the low-pressure steam into the ejector, mixes it with the ejection water, heats the ejection water, and thus recovers the heat energy in the steam condensate.

[0004] In the above-mentioned design, when recycling condensed water, steam mostly directly contacts the wall of the recovery tank to generate condensed water. Condensed water droplets and water columns hang on the tank wall for a long time, reducing the heat exchange area of ​​the tank wall, which not only affects the subsequent condensation of steam, but also affects the efficient discharge of condensed water, which is not conducive to the efficient recovery of condensed water. Therefore, this problem needs to be solved urgently. Utility Model Content

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0024] like Figure 1-Figure 4 As shown, a condensate recycling device of a temperature reducing and pressure reducing device provided in this embodiment comprises a recovery box 1, a diverter slot plate 9 is evenly and sealedly installed on the bottom of the inner wall of the recovery box 1, a condensate metal rod 11 and a lifting screw 8 which pass through the bottom of the recovery box 1 are arranged between the diverter slot plates 9; a transmission pulley group 14 is nested on the top of the lifting screw 8, and a transmission belt 4 is also wound around the transmission pulley group 14; a scraper plate 10 is slidably connected to the top of the lifting screw 8 and the condensate metal rod 11, the lifting screw 8 is made of stainless steel, and the condensate water is high-purity water, so it will not corrode the lifting screw 8.

[0025] An S-bend channel is formed between the diversion trough plate 9 and the inner wall of the recovery box 1. A steam inlet pipe 2 is inserted on one side of the outer wall of the recovery box 1, and a condensate drainage groove 7 is opened on the other side. The steam inlet pipe 2 and the condensate drainage groove 7 are both connected to the S-bend channel. The flow speed of steam in the S-bend channel is determined by the delivery pressure of the external pump body.

[0026] A servo motor 3 is installed on one side of the transmission belt 4. The servo motor 3 is connected to an operating panel 13 on the outer wall of the recovery box 1 through a wire. The servo motor 3 can control the regular and slow lifting and lowering of the scraper plate 10 through the operating panel 13. The position of the scraper plate 10 is lower than the top of the condensation metal rod 11, so that the liquid scraped off when it is raised can be discharged from the scraper plate 10 to the bottom.

[0027] A hot water exchange tank 6 is screwed onto the outer bottom of the recovery box 1, and the bottom end of the condensing metal rod 11 extends into the inside of the hot water exchange tank 6. A hot water exchange pipe 15 is plugged into one side of the outer wall of the hot water exchange tank 6, and a cooling fan 5 is fixed to the other side of the outer wall of the hot water exchange tank 6. The cooling fan 5 can be selectively turned on. If the hot water source is not used a second time, it is turned on to maintain the heat dissipation and cooling of the condensing metal rod 11. If the hot water source is used a second time, the cooling fan 5 is turned off, the hot water exchange pipe 15 is opened, and new cooling water is added to maintain circulation.

[0028] A sealing ring 12 is clamped at the contact portion between the lifting screw rod 8 and the recovery box 1 .

[0029] The scraper plate 10 is in sliding contact with the condensation metal rod 11 , the recovery box 1 and the diversion slot plate 9 .

[0030] Working principle of this device:

[0031] Step 1: The device is connected to an external power source, and the steam discharged from the temperature and pressure reducer is introduced into the recovery box 1 from the steam inlet pipe 2. The diverter plate 9 in the recovery box 1 and the inner wall of the recovery box 1 form a sealed S-bend channel. The steam enters from the entrance of the bend, contacts the diverter plate 9, the inner wall of the recovery box 1 and the condensation metal rod 11, and continues to flow forward. The high-temperature steam liquefies on the low-temperature outer wall structure to produce condensed water. As the condensed water accumulates, it falls to the bottom and flows along the S-bend until it is finally discharged from the condensed water drainage groove 7 for centralized collection and utilization;

[0032] Step 2: During the heat exchange process, the condensing metal rod 11 transfers heat to the cooling water in the bottom water exchange tank 6. The cooling water can be discharged from the water exchange pipe 15 and circulated externally, or it can be retained in the water exchange tank 6. The cooling fan 5 is turned on to cool down and maintain efficient condensation of the condensing metal rod 11.

[0033] Step 3: In addition, after a long period of condensation, water droplets and water columns will accumulate on the condensation metal rod 11 and the diversion trough plate 9. These liquids cannot drain smoothly and will cover the metal to reduce the thermal conductivity of the metal. At this time, the servo motor 3 drives the transmission belt 4 and the transmission pulley group 14 to work. The transmission pulley group 14 drives the bottom lifting screw 8 to rotate, which can push the scraper plate 10 to scrape down along the condensation metal rod 11 and the outer wall of the diversion trough plate 9 to scrape the liquid, thereby improving the drainage efficiency of the condensed water, and thus improving the recovery efficiency of the condensed water.

[0034] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
