[0031] like Figure 1-4 As shown, the vent tank comprises a cylinder 9 and four legs 1 at the bottom of the cylinder 9, evenly distributed across the bottom. A head 12 is located at the top of the cylinder 9. The sidewalls of the cylinder 9 are equipped with an exhaust port 13, a nitrogen inlet 15, and interfaces a8 and a11 for the liquid level gauge. The bottom of the cylinder 9 is connected to an air inlet 3 via a pipe 7. The side of the pipe 7 is connected to interfaces b18 and b19 for the liquid level gauge, respectively, via side pipes 4. Flanges 2 are attached to the exhaust port 13, nitrogen inlet 15, interfaces a8 and b11 for the liquid level gauge, the air inlet 3, the interfaces b18 and b19 for the liquid level gauge, and the interfaces b19 for the liquid level gauge. A nameplate 10 is located on the side of the cylinder 9, and a lifting lug 16 is located on the top to facilitate lifting the cylinder. The device is convenient for backwashing the lower connecting device, and can also detect the liquid inflow situation in the lower connecting device through the provided liquid level meter interface and liquid level transmitter interface. The device is easy to install and use, and the stability is increased by the provided support legs.

[0032] The top of the head 12 is connected to the pressure gauge port 14, the safety valve port 5, and the pressure transmitter port 17 through pipes. Each of these ports is connected to a flange 2. The flange connection between the device and the external connection prevents rust caused by welding at the interface, while also increasing the torque resistance of the interface and making it less susceptible to breakage.

[0033] The side pipe 4 is arranged horizontally, and its upper side is connected to the bottom of the cylinder 9 by a support rib 6. The angle between the support rib 6 and the side pipe 4 is 59-60 degrees. The support rib 6 is provided on the side pipe to strengthen the stability of the side pipe 4 and make the device structure more solid.

[0034] When the device is in use, when the lower connecting equipment is backwashing, the device takes in air from the nitrogen inlet 15, and the nitrogen enters the lower equipment through the bottom air inlet 3 for backwashing operation. The device connected to the pressure gauge interface 14 and the pressure transmitter interface 17 on the top of the head 12 monitors the pressure in the cylinder 9 in real time to ensure safe operation. When the lower connecting equipment starts to take in liquid, the liquid overflows from the bottom air inlet 3 into the cylinder 9 when the liquid filling is completed. The device connected to the liquid level gauge interface and the level transmitter interface on the cylinder detects the liquid level, which is convenient for the control room to control the overall operation. This device can be used to store nitrogen for backwashing of the lower connecting device, and can also detect the liquid inflow situation in the lower connecting device through the set detection component. The device is easy to install and use.

[0035] The embodiments described above are merely descriptions of preferred implementation methods of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made by technical personnel in this field to the technical solution of the present invention should be included in the scope of protection determined by the claims of the present invention.
