[0021] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0022] Please refer to Figure 1 As shown, a steam condensate recovery device of the utility model includes:

[0023] The collecting tank 1 is connected to the steam condensate inlet pipe 13, the drain pipe and the delivery pipe respectively;

[0024] The delivery tank 2 is connected to the delivery pipe and the recovery pipe 29 respectively, and a liquid level sensor is provided in the delivery tank 2;

[0025] The high-pressure steam intake assembly is communicated with the delivery tank 2 and connected to the liquid level sensor.

[0026] From the above description, it can be seen that the beneficial effects of the present invention are: a steam condensate recovery device, high-temperature steam water can smoothly enter the collection device from the steam condensate inlet pipe 13 at the top of the collection tank 1, realizing the steam condensate collection process, and at the same time, high-pressure steam can enter the conveying device from the high-pressure steam inlet pipe 28, providing power support for the subsequent conveying process, and the recovery pipe 29 provides an outflow channel for the treated water so that it can enter the next link for recycling. The setting of each pipeline clarifies the entry and exit paths of steam condensate and related gases in the entire device, ensuring the normal operation of the system. The liquid level sensor is located inside the conveying tank 2 and can sense the changes in the liquid level in the tank in real time. When the liquid level reaches a certain value, the high-pressure steam inlet pipe 28 connected to the liquid level sensor will introduce high-pressure steam to promote the flow of water in the tank. When the liquid level in the collection tank 1 is too high, the water can be discharged through the drain pipe. The steam condensate recovery device provided by the utility model can realize the efficient collection and transportation of steam condensate through the close coordination between the collection device, the transportation device and the safety device. At the same time, it can effectively ensure the safe operation of the equipment, greatly improve the energy utilization efficiency, significantly reduce energy waste, effectively reduce the frequency of equipment failures, and thus reduce the investment and operating costs of the equipment.

[0027] In an optional embodiment, a first gate valve 12 is provided on the drainage pipe, and a second gate valve 26 is provided on the delivery pipe.

[0028] As can be seen from the above description, the first gate valve 12 and the second gate valve 26 are used to control the flux of the drainage pipe and the delivery pipe.

[0029] In an optional embodiment, the collecting tank 1 is provided with a pressure relief valve 3 , which is connected to the exhaust pipe.

[0030] From the above description, it can be seen that when the pressure in the collection tank 1 is too high, the pressure relief valve 3 can release the excess pressure through the exhaust pipe connected to the top, thereby ensuring the safety of the entire device and avoiding damage to the device or safety accidents due to excessive pressure.

[0031] In an optional embodiment, the high-pressure steam intake assembly includes an intake pipe and a ball valve 23 and a second pressure gauge 24 provided on the intake pipe. The intake pipe is connected to the delivery tank 2, and the ball valve 23 is connected to the liquid level sensor.

[0032] As can be seen from the above description, the ball valve 23 can control the amount of high-pressure steam entering, and the pressure gauge can monitor the intake pressure to ensure that the input of high-pressure steam meets the system requirements.

[0033] In an optional embodiment, the air inlet pipe is connected to a first connecting pipe between the ball valve 23 and the second pressure gauge 24 . The first connecting pipe is connected to the delivery pipe, and a steam trap 25 is provided on the first connecting pipe.

[0034] As can be seen from the above description, the condensed water in the high-pressure steam inlet pipe 28 can enter the steam trap 25 through the inlet of the steam trap 25 located between the ball valve 23 and the pressure gauge, and then be discharged from the outlet through the first connecting pipe (located in front of the second gate valve 26) to the delivery tank 2. The steam trap 25 plays the role of separating and discharging the condensed water, ensuring the steam quality in the high-pressure steam inlet pipe 28 and preventing the condensed water from causing adverse effects on the system.

[0035] In an optional embodiment, a pressure balancing pipe is provided between the collecting tank 1 and the delivery tank 2 .

[0036] It can be seen from the above description that the pressure balancing pipe is used to balance the pressure between the delivery tank 2 and the collection tank 1 .

[0037] In an optional embodiment, a U-shaped pipe 11 is provided between the collection tank 1 and the drain pipe.

[0038] From the above description, it can be seen that the steam condensate inlet pipe 13 is set at the top of the collection tank 1 to facilitate the reception of steam condensate from above. When the liquid level of the collection tank 1 is too high, the water can be discharged through the U-shaped tube 11 on the upper side and the connected drain pipe (controlled by the first gate valve 12). The design of the U-shaped tube 11 can prevent the backflow of water, and the first gate valve 12 can control the timing and flow of the discharge.

[0039] In an optional embodiment, the recovery pipe 29 is connected to the drain pipe through a second connecting pipe, and a third gate valve 27 is provided on the second connecting pipe.

[0040] From the above description, it can be seen that the third gate valve 27 on the recovery pipe 29 can control the flow direction of the recovered water. When the path of the recovered water needs to be adjusted, it can be achieved by operating the third gate valve 27, and its outlet is connected to the second connecting pipe to ensure that the recovered water can flow according to the predetermined path and enter the next link for recycling.

[0041] In an optional embodiment, a first pressure gauge 22 is provided on the delivery tank 2 .

[0042] From the above description, it can be seen that the first pressure gauge 22 is located at the top of the delivery tank 2, and can monitor the pressure at the top of the delivery tank 2 in real time. It is connected to the top of the collecting tank 1 through a pressure balancing pipe, which can balance the pressure between the two and avoid system instability or failure due to excessive pressure difference.

[0043] In an optional embodiment, the steam condensate inlet pipe 13 and the drain pipe are both connected to the top of the collection tank 1, the delivery pipe is respectively connected to the bottom of the collection tank 1 and the bottom of the delivery tank 2, and the recovery pipe 29 is connected to the bottom of the delivery tank 2.

[0044] As can be seen from the above description, the outlet of the collecting tank 1 is located at the bottom of the collecting tank 1, the inlet of the conveying tank 2 is located at the lower side of the conveying tank 2, the outlet of the conveying tank 2 is connected to the recovery pipe 29, the steam condensate water inlet pipe 13 is set at the top of the collecting tank 1, and the U-shaped pipe 11 is set at the upper side of the collecting tank 1. Due to the effect of its own gravity, the water in the collecting tank 1 will flow out from the outlet at the bottom and flow to the inlet at the lower side of the conveying tank 2 through the conveying pipe. This layout conforms to the principle that water flows to lower places and is conducive to the natural transmission of water. The second gate valve 26 is installed on the conveying pipe, which can accurately control the opening and closing of the water flow channel and can adjust the water flow or cut off the water flow according to actual needs. The outlet of the conveying tank 2 is located at the lower side and connected to the recovery pipe 29, which provides a reasonable path for the outflow of recycled water, so that the treated water can smoothly enter the next link.

[0045] The operating principle of this utility model is as follows: high-temperature steam water enters through the water inlet pipe at the top of collection tank 1 and accumulates in collection tank 1 due to gravity. If the liquid level is too high, it can be discharged through the U-shaped pipe 11 and the drain pipe (controlled by the first gate valve 12). The water in collection tank 1 flows through the bottom outlet and the delivery pipe (controlled by the second gate valve 26) to the lower side inlet of delivery tank 2. A float 21 in delivery tank 2 senses the liquid level. When it reaches a certain value, steam is introduced through the high-pressure steam inlet pipe 28 (with a ball valve 23 and a pressure gauge) connected to the float 21 to increase the pressure. If condensate is present in the inlet pipe, it is collected at the inlet of the steam trap 25 (located between the ball valve 23 and the pressure gauge) and discharged from the outlet through the delivery pipe (before the second gate valve 26) to delivery tank 2. The first pressure gauge 22 at the top of delivery tank 2 is connected to the top of collection tank 1 through a pressure equalization pipe to balance the pressure. After the pressure in delivery tank 2 increases, the water flows through the recovery pipe 29 (with a three-way valve and a third gate valve 27, the outlet of the third gate valve 27 connected to the delivery pipe for flow control) to the next stage of recycling. When the pressure in the collecting tank 1 is too high, the pressure is released from the exhaust pipe through the pressure relief valve 3. The third gate valve 27 can be opened to discharge the water inside the collecting tank 1 and the delivery tank 2.

[0046] Please refer to Figure 1 As shown, the first embodiment of the present invention is: a steam condensate recovery device, comprising:

[0047] The collecting tank 1 is connected to the steam condensate inlet pipe 13, the drain pipe and the delivery pipe respectively;

[0049] The high-pressure steam intake assembly is communicated with the delivery tank 2 and connected to the liquid level sensor.

[0050] The drain pipe is equipped with a first gate valve 12, and the delivery pipe is equipped with a second gate valve 26. A pressure relief valve 3 is installed on the collection tank 1 and connected to the exhaust pipe. The high-pressure steam intake assembly includes an intake pipe, a ball valve 23, and a second pressure gauge 24. The intake pipe is connected to the delivery tank 2, and the ball valve 23 is connected to the liquid level sensor. A first connecting pipe is connected to the delivery pipe between the ball valve 23 and the second pressure gauge 24. The first connecting pipe is connected to the delivery pipe and is equipped with a steam trap 25. A pressure equalizing pipe is installed between the collection tank 1 and the delivery tank 2. A U-shaped pipe 11 is installed between the collection tank 1 and the drain pipe. A recovery pipe 29 is connected to the drain pipe via a second connecting pipe, equipped with a third gate valve 27. A first pressure gauge 22 is installed on the delivery tank 2. The steam condensate inlet pipe 13 and the drain pipe are both connected to the top of the collection tank 1. The delivery pipe is connected to the bottoms of the collection tank 1 and the delivery tank 2, respectively. The recovery pipe 29 is connected to the bottom of the delivery tank 2. The main body and pipelines of the steam condensate recovery device are made of stainless steel. The use of stainless steel can make the device have good corrosion resistance and high strength, and can operate stably for a long time in a complex environment, extending the service life of the device. At the same time, it ensures the sealing and stability of the pipeline and reduces the risk of leakage and damage caused by material problems.

[0051] In summary, in the steam condensate recovery device of the present invention, high-temperature steam water can smoothly enter the collection device from the steam condensate inlet pipe on the top of the collection tank, realizing the steam condensate collection process. At the same time, high-pressure steam can enter the conveying device from the high-pressure steam inlet pipe, providing power support for the subsequent conveying process, and the recovery pipe provides an outflow channel for the treated water so that it can enter the next link for recycling. The setting of each pipeline clarifies the entry and exit paths of steam condensate and related gases in the entire device, ensuring the normal operation of the system. The liquid level sensor is located inside the conveying tank and can sense the changes in the liquid level in the tank in real time. When the liquid level reaches a certain value, the high-pressure steam inlet pipe connected to the liquid level sensor will introduce high-pressure steam to promote the flow of water in the tank. When the liquid level in the collection tank is too high, the water can be discharged through the drain pipe.

At the same time, it can effectively ensure the safe operation of the equipment, greatly improve the energy utilization efficiency, significantly reduce energy waste, effectively reduce the frequency of equipment failures, and thus reduce the investment and operating costs of the equipment.
