Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0036] In the description of the present application, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present application.

[0037] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0038] Steam, as a widely used heating and humidifying medium, plays a vital role in the drying process and air conditioning system. During the working process of steam, part of the steam will condense into water. If the condensed water is not treated and discharged directly, it will cause waste.

[0039] Therefore, in order to reduce waste, in some cases, a condensate recovery device is set up to recover the condensate generated by condensate generating devices such as boilers or air conditioners, so as to reuse the condensate and reduce waste.

[0040] Generally, the condensate recovery device includes a pump, a recovery pipe and a treatment device. The pump and the treatment device are both connected to the condensate generating device and are connected to each other through the recovery pipe. In this way, during operation, the pump can pump the condensate in the condensate generating device to the treatment device, which will treat the condensate. After that, the condensate can flow back to the condensate generating device to complete the cycle, realize the recycling and reuse of condensate, and reduce the waste of energy and water, which has a positive effect on environmental protection and system reliability.

[0041] However, during the operation of the condensate recovery device, it is inevitable that water will accumulate in the recovery pipe, which will corrode the pipe wall over time and affect the condensate recovery efficiency. Moreover, if the corrosion is severe, rusty water will be easily generated, which is not only not conducive to the normal operation of condensate generating devices such as boilers and air conditioners, but also brings safety hazards.

[0042] It can be seen that the condensate recovery device has problems such as low recovery efficiency, which needs to be improved.

[0043] Figure 1 The structure of the condensate recovery device of the present application is shown exemplarily.

[0044] See also Figure 1 The condensed water recovery device 10 provided in the present application includes a pump 1, a processing device 2 and a recovery pipe 3. The pump 1 is used to be connected to the condensed water generating device to extract the condensed water in the condensed water generating device. The processing device 2 is used to be connected to the condensed water generating device to treat the condensed water and return the treated condensed water to the condensed water generating device. The recovery pipe 3 connects the pump 1 and the processing device 2 so that the condensed water extracted from the condensed water generating device by the pump 1 flows to the processing device 2 via the recovery pipe 3. Among them, a water outlet 32 ​​is provided on the bottom wall 31 of the recovery pipe 3 to discharge the condensed water in the recovery pipe 3.

[0045] By setting a water outlet 32 ​​on the bottom wall 31 of the recovery pipe 3, the condensed water in the recovery pipe 3 can be conveniently discharged when needed, preventing the condensed water from accumulating in the recovery pipe 3 and corroding the pipe wall, thereby affecting the recovery efficiency. Therefore, the recovery efficiency of the condensed water recovery device 10 can be effectively improved.

[0046] Moreover, setting a water outlet 32 ​​to discharge the condensed water in the recovery pipe 3 can also prevent the condensed water from seriously corroding the pipe wall and generating rusty water, so as not to affect the normal operation of the condensed water generating device or even cause a safety accident. Therefore, it is also beneficial to the normal operation of the condensed water generating device and improves work safety.

[0047] It can be seen that by arranging the water outlet 32 ​​on the bottom wall of the recovery pipe 3, the condensate recovery efficiency of the condensate recovery device 10, as well as the structural reliability and working safety of the condensate recovery device 10 can be effectively improved.

[0048] In order to facilitate the condensed water to flow out from the water outlet 32, see Figure 1 In some embodiments, the bottom wall 31 of the recovery pipe 3 is inclined toward the water outlet 32, that is, the end of the bottom wall of the recovery pipe 3 close to the water outlet 32 ​​is lower than the end of the bottom wall of the recovery pipe 3 away from the water outlet 32. In this way, the water in the recovery pipe 3 can be guided by the inclined bottom wall 31 and gathered toward the water outlet 32, so that the condensed water can flow out of the water outlet 32 ​​more conveniently, and the condensed water in the recovery pipe 3 can be discharged more fully.

[0049] The bottom wall 31 of the recovery pipe 3 may be inclined toward the water outlet 32 ​​on only one side, or on both sides, that is, the portion of the bottom wall 31 of the recovery pipe 3 located on at least one side of the water outlet 32 ​​may be inclined toward the water outlet 32. Figure 1 When the parts of the bottom wall 31 of the recovery pipe 3 located on both sides of the water outlet 32 ​​are inclined toward the water outlet 32, the water outlet 32 ​​is located at the bottom of the recovery pipe 3, and the condensed water on both sides of the water outlet 32 ​​in the recovery pipe 3 can be gathered to the water outlet 32. In this way, the condensed water can be discharged more cleanly and thoroughly, which is beneficial to further improve the recovery efficiency, improve the structural reliability and work safety.

[0050] Continue to see Figure 1 In some embodiments, the condensate recovery device 10 includes not only a pump 1, a processing device 2 and a recovery pipe 3, but also a control valve 4. The control valve 4 is disposed at the water outlet 32 ​​to control the opening and closing of the water outlet 32. In this way, when the condensate does not need to be discharged, the control valve 4 can control the water outlet 32 ​​to be closed so that the condensate can flow smoothly to the processing device 2 for normal circulation. When the accumulated water needs to be discharged, the control valve 4 can control the water outlet 32 ​​to be opened to discharge the accumulated water, which is flexible and convenient.

[0051] The control mode of the control valve 4 is not limited, and it can be automatic, manual, or an integrated automatic and manual mode. When the control valve 4 is an automatic and manual integrated valve, it can be opened and closed manually or automatically, so it is more convenient to use and can achieve more flexible and diverse drainage modes. For example, it can usually be automatically controlled to drain water efficiently, and in special cases, if manual intervention is required, it can also be manually controlled to drain water safely.

[0052] Also, see Figure 1 In some embodiments, the condensed water recovery device 10 includes not only a pump 1, a processing device 2 and a recovery pipe 3, but also a liquid level meter 5. The liquid level meter 5 is arranged on the recovery pipe 3 to detect the liquid level of the condensed water in the recovery pipe 3. In this way, the liquid level of the condensed water in the recovery pipe 3 can be monitored in real time, so as to conveniently and timely and accurately understand the amount of condensed water in the recovery pipe 3, so as to timely and accurately control whether to discharge the condensed water.

[0053] See also Figure 1 In some embodiments, the condensate recovery device 10 includes a control valve 4 and a liquid level meter 5, and the control valve 4 is connected to the liquid level meter 5 by signal, so that when the liquid level meter 5 detects that the condensate level in the recovery pipe 3 reaches a preset value, the water outlet 32 ​​is opened. In this way, a more accurate and efficient water discharge process can be achieved.

[0054] In the above embodiments, the treatment device 2 can treat the condensed water in various ways, as long as the treated condensed water meets the requirements of flowing back to the condensed water generating device to participate in the circulation. Figure 1 In some embodiments, the processing equipment 2 includes a deoxygenated water tank 21. At this time, the processing equipment 2 can heat and deoxygenate the condensed water, so that the temperature of the condensed water increases and the oxygen content decreases. This is more conducive to reducing the corrosion of the condensed water to the condensed water generating device, improving the structural reliability and working safety of the condensed water generating device, and extending the service life of the condensed water generating device.

[0055] In addition, as a further improvement to the above embodiments, see Figure 1 The condensed water recovery device 10 further includes a heat preservation member 6, which is disposed on the recovery pipe 3 for heat preservation. In this way, the heat loss of the condensed water when flowing through the recovery pipe 3 can be reduced, and energy waste can be reduced. In particular, when the processing equipment 2 includes a deoxygenated water tank 21, the heat preservation member 6 is disposed to insulate the recovery pipe 3, and the condensed water flowing into the deoxygenated water tank 21 can have a higher temperature, so that the deoxygenated water tank 21 only needs to heat the condensed water to a small extent, that is, the condensed water can be heated to the target temperature, therefore, it is beneficial to reduce the energy consumption at the deoxygenated water tank 21, and further save energy and reduce emissions.

[0056] The structure of the heat-insulating member 6 can be varied. Figure 1 In some embodiments, the heat-insulating member 6 includes heat-insulating cotton 61. In this way, the heat-insulating property of the heat-insulating cotton 61 can be utilized to effectively keep warm and prevent the condensed water from cooling too much when flowing in the recovery pipe 3, thereby affecting the energy utilization rate. Moreover, the heat-insulating cotton 61 can well adapt to the shape characteristics of the recovery pipe 3 and fully contact the recovery pipe 3, so that a better heat-insulating effect can be achieved.

[0057] The heat-insulating cotton 61 can be arranged on the outer wall of the recovery pipe 3, or can also be arranged on the inner wall of the recovery pipe 3. When the heat-insulating cotton 61 is arranged on the outer wall of the recovery pipe 3, it is more convenient to arrange the heat-insulating cotton 61, and the heat-insulating cotton 61 does not directly contact with the condensed water, is not easily corroded, and has a longer service life.

[0058] Next, combine Figure 1 The illustrated embodiments further illustrate the present application.

[0059] like Figure 1 As shown, in this embodiment, the condensate recovery device 10 includes a pump 1, a deoxygenated water tank 21, a recovery pipe 3, a control valve 4, a liquid level meter 5 and thermal insulation cotton 61.

[0060] The pump 1 is used to be connected to the condensed water generating device to extract the condensed water in the condensed water generating device.

[0061] The deoxygenated water tank 21 is used to be connected to the condensed water generating device to heat and deoxygenate the condensed water, and to return the heated and deoxygenated condensed water to the condensed water generating device.

[0062] The recovery pipe 3 connects the pump 1 and the deoxygenated water tank 21 to achieve communication between the pump 1 and the deoxygenated water tank 21, so that the condensed water drawn from the condensed water generating device by the pump 1 flows to the deoxygenated water tank 21 via the recovery pipe 3. Figure 1 As shown, in this embodiment, a water outlet 32 ​​is provided on the bottom wall 31 of the recovery pipe 3, and the bottom wall 31 of the recovery pipe 3 is tilted, and its parts located on both sides of the water outlet 32 ​​are tilted toward the water outlet 32, so that the condensed water in the recovery pipe 3 can be gathered toward the water outlet 32, which is convenient for discharging the accumulated water in the recovery pipe 3. In this way, it can prevent the condensed water from accumulating too much in the recovery pipe 3 and corroding the pipe wall, so as not to reduce the recovery efficiency, affect the normal operation of the condensed water generating device, and even cause a safety accident.

[0063] The control valve 4 is arranged on the recovery pipe 3 and located at the water outlet 32, and is used to control the opening and closing of the water outlet 32. In this embodiment, the control valve 4 is a manual-automatic electric valve, which can be remotely controlled to open and close automatically, and can also be manually controlled to open and close manually.

[0064] The liquid level meter 5 is arranged on the recovery pipe 3 and extends into the recovery pipe 3, and is used to detect the liquid level of condensed water in the recovery pipe 3 to realize real-time monitoring of the liquid level of condensed water, and then together with the control valve 4, timely and accurately control the discharge of accumulated water in the recovery pipe 3.

[0065] Specifically, the control valve 4 of this embodiment has the following three control modes:

[0066] (1) When pump 1 stops working for a period of time, control valve 4 opens to drain the accumulated water;

[0067] (2) When the liquid level meter 5 detects that the liquid level reaches the preset value, the control valve 4 opens to drain the accumulated water in time;

[0068] (3) When manual intervention is required, the remote control can be cut off and the control valve 4 can be opened manually to drain the accumulated water in time.

[0069] The insulation cotton 61 is wrapped on the outer wall of the recovery pipe 3 to insulate the condensed water in the recovery pipe 3 and slow down the temperature loss of the condensed water in the process of flowing through the recovery pipe 3. In this way, the condensed water flowing to the deoxygenated water tank 21 has a higher temperature and only needs to absorb less energy to reach the target temperature. Therefore, it is more energy-saving and environmentally friendly.

[0070] It can be seen that this embodiment provides a water outlet 32, a control valve 4 and a liquid level meter 5 on the bottom wall 31 of the recovery pipe 3, and tilts the bottom wall 31 of the recovery pipe 3, so that the water accumulated in the pipe can be removed promptly and effectively to improve the recovery efficiency. Moreover, by wrapping the outer wall of the recovery pipe 3 with thermal insulation cotton 61, the energy loss in the condensed water recovery process can be effectively reduced, the thermal stability of the system can be improved, the demand for additional energy can be reduced, and the energy utilization efficiency can be improved.

[0071] In addition, the present application also provides a condensate recovery system, which includes a condensate generating device and also includes the condensate recovery device 10 of any embodiment of the present application. The condensate generating device can be various devices capable of generating condensate, such as a boiler or an air conditioner.

[0072] The above description is only an exemplary embodiment of the present application and is not intended to limit the present application.
