[0002] The steam discharged from the process or the secondary steam generated in the process of recovering high-temperature condensed water is called exhaust steam. Due to its low pressure, the exhaust steam cannot meet the requirements of steam-using equipment. Therefore, many power stations of industrial and mining enterprises and heating centers of public institutions often discharge it directly, resulting in a large waste of heat and water resources and pollution to the environment. For example, the patent with publication number CN213119043U discloses a fixed exhaust steam recovery device, including an exhaust pipe, a U-shaped pipe and a drain pipe. The exhaust pipe is connected to the exhaust port on the top of the boiler fixed exhaust to lead out the fixed exhaust steam; the U-shaped pipe is arranged at The outlet end of the exhaust pipe is located below the exhaust pipe, and a pipe elbow is formed at the connection between the U-shaped pipe and the exhaust pipe. A water inlet is provided at the pipe elbow for filling cooling water into the U-shaped pipe to mix the exhaust steam with the cooling water; the drain pipe is connected to the other end of the U-shaped pipe relative to the exhaust pipe, and the connection between the drain pipe and the U-shaped pipe is lower than the connection between the U-shaped pipe and the exhaust pipe to form a liquid level difference; the device recovers the exhaust steam by mixing the exhaust steam with the liquid, and cannot realize a gas-liquid separator, so it is not convenient to recover the exhaust steam mixed with harmful gases, resulting in a small scope of application.

[0003] To this end, the utility model provides a waste steam recovery device. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a waste steam recovery device, comprising a U-shaped tube 1, an air inlet pipe 2 is fixed at one end of the U-shaped tube 1, an air outlet pipe 3 is fixed at the other end of the U-shaped tube 1, an exhaust device and a purification device are installed in the air outlet pipe 3, a refrigeration device is fixed on the air outlet pipe 3, a condensing device is installed on the U-shaped tube 1, a water outlet pipe 6 is installed at the bottom of the U-shaped tube 1, a water spray head 5 is fixed in the U-shaped tube 1, a water inlet pipe 4 is fixed on the U-shaped tube 1, and the water inlet pipe 4 is connected to the water spray head 5.

[0022] In this embodiment, the air inlet pipe 2 and the air outlet pipe 3 are both fixed to the U-shaped tube 1 at an angle, the angle between the air inlet pipe 2 and the air outlet pipe 3 and the U-shaped tube 1 is 135°, the water outlet pipe 6 is connected to the U-shaped tube 1, a water tank 7 is installed on the lower side of the U-shaped tube 1, and one end of the water outlet pipe 6 is connected to the water tank 7.

[0023] Specifically, the exhaust steam enters the U-shaped tube 1 from the air inlet pipe 2, and then after condensation in the U-shaped tube 1, the exhaust steam will be initially separated into gas and liquid, the gas enters the air outlet pipe 3 and is discharged, and then is further separated into gas and liquid by the refrigeration device to ensure that the gas is dry, and the separated liquid flows out through the water outlet pipe 6 into the water tank 7, and the liquid can be recovered.

[0024] Liquid can be sprayed into the U-shaped tube 1 through the water inlet pipe 4 and the water spray head 5, so that the exhaust steam is mixed with the liquid to ensure the recovery effect. At the same time, the water spray rate can be adjusted so that the water outlet pipe 6 always contains liquid, thereby preventing the gas from being discharged together.

[0025] The condensing device comprises a cooling jacket 8, which is fixedly connected to the U-shaped tube 1. The U-shaped tube 1 passes through the cooling jacket 8. A water inlet 9 and a water outlet 10 are provided on one side of the cooling jacket 8.

[0026] Specifically, cooling water can be introduced into the cooling jacket 8 through the water inlet 9. The cooling water cools the exhaust steam and is discharged from the water outlet 10, thereby ensuring the condensation effect and recovering the heat in the exhaust steam.

[0027] The refrigeration device is a refrigeration fin 11 , which is fixedly connected to the air outlet pipe 3 . The refrigeration fin 11 is located at one end of the air outlet pipe 3 close to the U-shaped tube 1 .

[0028] Specifically, the relatively cold temperature of the refrigeration plate 11 can condense the water vapor remaining in the exhaust steam, thereby ensuring that the exhausted gas is dry, and the condensed liquid will slide along the outlet pipe 3 into the U-shaped tube 1 .

[0029] The exhaust device comprises an exhaust fan 12 , and the exhaust fan 12 is fixed in the exhaust pipe 3 .

[0030] Specifically, when the pressure of the exhaust steam is too low, the exhaust fan 12 may be started, and the exhaust fan 12 may assist in exhausting the exhaust steam, thereby compensating for the pressure of the exhaust steam.

[0031] The purification device comprises a purifier 14 , on which a sealing ring 13 is fixed, and the purifier 14 is threadably matched with the air outlet pipe 3 .

[0032] Specifically, when the exhausted gas needs to be purified, the purifier 14 can be directly threadedly installed in the exhaust pipe 3, and when the exhausted gas does not need to be purified, the purifier 14 can be disassembled to reduce costs.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
