[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Example 1

[0026] This embodiment discloses as follows: Figure 1 As shown, a backflow prevention dual-channel condensate isolation structure for a steam safety venting system includes:

[0027] Main pipe 1, which is equipped with multiple vents.

[0028] The first branch pipe 2 has one end connected to the vent of the main pipe 1 and the other end connected to the inlet of the condenser 3. A first control valve 4 is installed on the first branch pipe 2.

[0029] The second branch pipe 5 is connected at one end to the outlet of the condenser 3 and at the other end to the condensate collection device 6. A second control valve 7 is installed on the second branch pipe 5.

[0030] Condensate collection device 6 is used to collect and store condensate from condenser 3.

[0031] The control device 8 is connected to the first control valve 4 and the second control valve 7, and is used to control the opening and closing of the first control valve 4 and the second control valve 7 according to the pressure in the main pipeline 1 and the liquid level in the condenser 3.

[0032] The control device 8 includes a pressure sensor 9 for detecting the pressure in the main pipeline 1 and transmitting the pressure signal to the control unit 10. The control device 8 also includes a level gauge 11 for detecting the liquid level in the condenser 3 and transmitting the liquid level signal to the control unit 10. The condenser 3 is a horizontal condenser containing a cooling medium to condense steam into condensate. The control device 8 further includes a display 12 for displaying the pressure in the main pipeline 1 and the liquid level in the condenser 3. The control device 8 also includes an alarm 13 that issues an alarm signal when the pressure in the main pipeline 1 exceeds a set safety value or the liquid level in the condenser 3 exceeds a set high value.

[0033] Both the first pipe 2 and the second pipe 5 are made of high-temperature resistant and corrosion-resistant materials.

[0034] The working principle of this utility model is as follows:

[0035] Under normal circumstances, both the first control valve 4 and the second control valve 7 are closed, and steam is transported normally within the main pipeline 1. When a malfunction in the steam system or other reasons cause the pressure in the main pipeline 1 to rise and reach the release pressure, the pressure sensor 9 installed on the main pipeline 1 transmits a signal to the control device 8. Upon receiving the signal, the control device 8 controls the first control valve 4 to open, allowing steam to enter the condenser 3 through the first branch pipeline 2. Inside the condenser 3, the steam is cooled by the cooling medium and condenses into condensate. As condensate is continuously produced, the liquid level in the condenser 3 gradually rises. The level gauge 11 monitors the liquid level in real time and transmits a signal to the control device 8. When the liquid level reaches the set high value, the control device 8 controls the second control valve 7 to open, and the condensate flows into the condensate collection device 6 through the second branch pipeline 5 under gravity. When the pressure in the main pipeline 1 returns to normal, the pressure sensor 9 sends a signal back to the control device 8, which then controls the first control valve 4 to close, stopping the release of steam. Meanwhile, based on the drop in liquid level in condenser 5, control device 8 controls the opening of second control valve 7 until it is completely closed, completing one steam release and condensate treatment process.

[0036] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
