Description

Technical Field

[0001] This utility model belongs to the field of waste gas purification technology, specifically, it relates to an venting device. Background Technology

[0002] Since the main component of natural gas is methane, a reactive greenhouse gas, direct release of methane into the air would pollute the environment. Therefore, natural gas is usually treated through venting tanks, where it is ignited to produce carbon dioxide and water. Treating natural gas in venting tanks typically requires manual ignition using a bamboo pole or a magic bullet, which is inconvenient and carries significant safety risks. Other ignition methods exist, but poor flow control could lead to flashover, posing a substantial safety hazard. Utility Model Content

[0003] One objective of this invention is to provide a venting device to prevent flashover during ignition, improve ignition safety, and enhance venting efficiency.

[0004] According to this utility model, a venting device is provided, comprising: a venting tank, a plurality of burners disposed in the venting tank, a venting pipe with a first end connected to the burners, and a first control valve disposed on the venting pipe, the second end of the venting pipe being connected to a gas source, the section of the venting pipe between the first control valve and the gas source being connected to any of the burners via a bypass pipe, the diameter of the bypass pipe being smaller than the diameter of the venting pipe, and a second control valve being disposed on the bypass pipe near the venting pipe.

[0005] In a preferred embodiment, a support frame is fixedly installed inside the vent tank, and the burner is fixedly installed on the support frame.

[0006] In a preferred embodiment, both the bypass pipe and the vent pipe are fixedly mounted on the support frame.

[0007] In a preferred embodiment, the system includes three burners arranged side-by-side on the support frame.

[0008] In a preferred embodiment, a baffle is provided on the outer periphery of the venting tank.

[0009] In a preferred embodiment, the baffle is fixed to the outer periphery of the venting tank by a hinge.

[0010] In a preferred embodiment, the baffle is made of steel.

[0011] In a preferred embodiment, the venting tank has a connecting port near its bottom, and a short pipe for quick connection to a water truck is provided in the connecting port, with a control valve provided on the short pipe.

[0012] In a preferred embodiment, the vent pipe has a diameter of 75 mm and the bypass pipe has a diameter of 20 mm.

[0013] In a preferred embodiment, a flame arrester is provided on the vent pipe section between the first control valve and the burner.

[0014] This utility model has at least the following technical effects: According to this utility model, a venting tank, multiple burners disposed within the venting tank, a venting pipe with its first end connected to the burners, and a first control valve disposed on the venting pipe are provided. The second end of the venting pipe is connected to a gas source. The section of the venting pipe between the first control valve and the gas source is connected to any burner via a bypass pipe. The diameter of the bypass pipe is smaller than the diameter of the venting pipe, and a second control valve is disposed on the bypass pipe near the venting pipe. Because the diameter of the bypass pipe is smaller than the diameter of the venting pipe, natural gas first flows to the burners through the smaller-diameter bypass pipe and is ignited, thereby avoiding flashover during ignition and improving ignition safety. Then, it flows to the burners through the larger-diameter venting pipe, thereby improving venting efficiency. Attached Figure Description

[0015] Figure 1 A schematic diagram of the overall structure of a venting device according to an embodiment of the present invention is shown.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0019] In this utility model, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figure 1 As shown, the venting device 100 of this utility model includes: a venting tank 1, a plurality of burners 3 disposed within the venting tank 1, a venting pipe a connected at its first end to one of the burners 3, and a first control valve 4 disposed on the venting pipe a. The second end of the venting pipe a is connected to a gas source for supplying natural gas. A bypass pipe 7 is connected to the section of the venting pipe a between the first control valve 4 and the gas source. The bypass pipe 7 is connected to any one of the burners 3, and its diameter is smaller than the diameter of the venting pipe a. A second control valve 6 is disposed on the bypass pipe 7 near the venting pipe a. It should be noted that the burners 3 are existing combustion equipment.

[0021] The following is a brief description of the venting process of the venting device 100 described in this utility model.

[0022] When the first control valve 4 is closed and the upstream gate valve is opened, natural gas from the gas source flows to the first control valve 4 through the vent pipe a. Then, the second control valve 6 is opened and the burner 3 is started. Natural gas flows to the burner 3 through the bypass pipe 7 and is ignited. When the second control valve 6 is closed and the first control valve 4 is opened, natural gas from the gas source flows directly to the burner 3 through the vent pipe a and burns there. When the flame indicates that the venting is about to be completed, the second control valve 6 is opened and the first control valve 4 is closed. The remaining natural gas from the gas source flows to any burner 3 through the bypass pipe 7 and burns until the flame is extinguished. Finally, the second control valve 6 is closed.

[0023] According to this utility model, a venting tank 1, a plurality of burners 3 disposed within the venting tank 1, a venting pipe a connected at its first end to the burners 3, and a first control valve 4 disposed on the venting pipe a are provided. The second end of the venting pipe a is connected to a gas source. The section of the venting pipe a between the first control valve 4 and the gas source is connected to any burner 3 via a bypass pipe 7. The diameter of the bypass pipe 7 is smaller than the diameter of the venting pipe a, and a second control valve 6 is disposed on the bypass pipe 7 near the venting pipe a. Because the diameter of the bypass pipe 7 is smaller than the diameter of the venting pipe a, natural gas first flows through the smaller diameter bypass pipe 7 to the burners 3 and is ignited, thereby avoiding flashover during ignition and improving ignition safety. Then, it flows through the larger diameter venting pipe a to the burners 3, thereby improving venting efficiency.

[0024] In one or more embodiments, a support frame 2 is fixedly installed inside the vent tank 1, and the burners 3 are all fixedly installed on the support frame 2.

Optionally, the baffle 9 is fixed to the outer periphery of the vent tank 1 by a hinge, and the baffle 9 can be folded up during transport of the vent tank 1 for convenient transportation. Optionally, the baffle 9 is made of steel.

[0028] In one or more embodiments, a flame arrester is provided on the section of the vent pipe a between the first control valve 4 and the burner 3 to prevent vent backfire.

[0029] In one or more embodiments, the vent pipe a has a diameter of 75 mm and the bypass pipe 7 has a diameter of 20 mm.

[0030] In one or more embodiments, the vent tank 1 is provided with a connection port 8 near its bottom, and a short pipe for quick connection to a water truck is provided in the connection port 8, and a control valve is provided on the short pipe.
