DETAILED DESCRIPTION
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example:
[0022] like Figs. 1-2 As shown, this embodiment proposes a steam pipe condensate recovery and utilization device for connection to the main steam pipe 10, including a condensate pipe 30, and a tee pipe 12 is provided on the main steam pipe 10, and the condensate pipe 30 is connected to the tee pipe 12.
[0023] A metal corrugated pipe 20 is installed on the drainage pipe 30, and the metal corrugated pipe 20 is connected to the tee pipe 12. A liquid collection cylinder 40 is installed at the other end of the drainage pipe 30. A liquid recovery pipe 70 is installed on the liquid collection cylinder 40. A drain pipe 80 is also installed on the liquid collection cylinder 40. A liquid level sensor 50 is installed inside the liquid collection cylinder 40. The liquid level sensor 50 and the drain pipe 80 work together to perform precise drainage.
[0024] In this case, the end of the drainage pipe 80 is connected to the rainwater well.
[0025] In this embodiment, when the main steam pipe 10 is drained, the drain pipe 30 is connected to the metal corrugated pipe 20, and the metal corrugated pipe 20 is connected to the tee pipe 12. When condensate is generated in the main steam pipe 10, the condensate enters the metal corrugated pipe 20 through the tee pipe 12 and enters the liquid collection cylinder 40 through the drain pipe 30 for storage. When the liquid level sensor 50 in the liquid collection cylinder 40 monitors the condensate in real time, when the condensate level reaches the alarm value of the liquid level sensor 50, the drain pipe 80 is opened, and the condensate is discharged into the rainwater well through the drain pipe 80. When the drain pipe 80 is not opened, the condensate is recycled and reused through the liquid recovery pipe 70.
[0026] By installing a metal bellows 20 on the condensate drain pipe 30 and using a liquid level sensor 50 to monitor the condensate level in the collection cylinder 40 in real time, the drain pipe 80 will automatically open when the condensate level reaches the preset alarm value, thus achieving precise drainage of condensate and effectively preventing condensate from accumulating in the pipe, thereby improving the operating efficiency and safety of the main steam pipe 10.
[0027] When the drain pipeline 80 is not opened, the condensed water can be recycled through the liquid recovery pipeline 70, realizing efficient utilization of condensed water resources, reducing energy consumption and water resource waste, having significant energy-saving effect, and meeting the development concept of green environmental protection.
[0028] Through the good flexibility and elasticity of the metal bellows 20, the vibration and mechanical impact generated in the operation process of the main steam pipeline 10 can be absorbed and buffered. This structure design can effectively isolate the transmission of vibration when the drain pipeline 30 is connected with the main steam pipeline 10, thereby avoiding problems such as loose connection, leakage or damage caused by vibration, and improving the stability and reliability of the entire drain system.
[0029] Specifically, the drain pipeline 80 is arranged below the liquid recovery pipeline 70, the drain pipeline 80 is provided with an electric valve 81, the electric valve 81 is provided with a controller, and the liquid level sensor 50 is connected with the controller.
[0030] In the embodiment, the controller is a PLC controller, the controller is connected with the liquid level sensor 50 and the electric valve 81 through a shielded cable, and the electric valve 81, the liquid level sensor 50 and the controller are powered by a power supply;
[0031] The controller processes the signal of the liquid level sensor 50 according to the preset liquid level threshold value such as the alarm liquid level, determines that the drain operation needs to be performed when the liquid level reaches the set alarm value, sends an opening instruction to the electric valve 81, and the electric valve 81 is opened after receiving the instruction. The condensed water is discharged through the drain pipeline 80, the liquid level gradually decreases with the discharge of the condensed water, and the controller sends a closing instruction to the electric valve 81 when the liquid level decreases to below the set safety value, the electric valve 81 is closed, and the drain process is completed.
[0032] Specifically, the liquid collecting cylinder 40 is provided with an exhaust hole 41, the exhaust hole 41 is on the top end face of the liquid collecting cylinder 40, and the exhaust hole 41 communicates with the inner cavity of the liquid collecting cylinder 40.
[0033] In the embodiment, during the process of storing the condensed water in the liquid collecting cylinder 40, the volume of the gas in the liquid collecting cylinder 40 is gradually compressed with the inflow of the condensed water. The existence of the exhaust hole 41 can ensure that the gas pressure inside and outside the liquid collecting cylinder 40 is balanced, prevent the liquid flow from being blocked or the pressure in the pipeline system from abnormally rising due to the pressure difference, help the condensed water to flow into the liquid collecting cylinder 40 smoothly, and avoid damage to the pipeline system caused by pressure accumulation.
[0034] Specifically, the liquid collecting cylinder 40 is provided with a blowdown pipe 60, the blowdown pipe 60 is arranged on the bottom end face of the liquid collecting cylinder 40, and the blowdown pipe 60 communicates with the inner cavity of the liquid collecting cylinder 40.
[0035] In the embodiment, the sewage pipe 60 is arranged to facilitate the treatment of the sewage in the liquid collecting cylinder 40.
[0036] Specifically, the hydrophobic pipeline 30 is provided with a hydrophobic gate valve 31, the liquid recovery pipeline 70 is provided with a recovery gate valve 71, and the sewage pipe 60 is provided with a sewage gate valve 61.
[0037] In the embodiment, the hydrophobic gate valve 31 can facilitate the control of the opening or closing of the hydrophobic pipeline 30, the recovery gate valve 71 can facilitate the control of the opening or closing of the liquid recovery pipeline 70, and the sewage gate valve 61 can facilitate the control of the opening or closing of the sewage pipe 60.
[0038] Specifically, the main steam pipeline 10 is provided with a perforated plate 11, and the tee pipe 12 is connected at the perforated plate 11.
[0039] In the embodiment, the perforated plate 11 is provided with a plurality of small holes, which can disperse and uniformly introduce the condensed water into the tee pipe 12, thereby avoiding the accumulation of the condensed water in the pipeline or the formation of a local high-pressure area, and due to the small diameter of the holes on the perforated plate 11, the steam loss can be effectively reduced, and the steam will be subjected to a certain resistance when passing through, thereby reducing the possibility of steam escaping from the hydrophobic pipeline 30.
[0040] Specifically, the perforated plate 11 is arranged at the bottom end of the main steam pipeline 10, and the liquid collecting cylinder 40 is arranged below the main steam pipeline 10.
