Description

Technical Field

[0001] The utility model relates to the technical field of natural gas odorizing devices, in particular to an intelligent odorizing device at the end of a natural gas pipeline network. Background Art

[0002] Intelligent odorization at the end of the natural gas pipeline network is an important link in ensuring the safe use of natural gas. Natural gas itself is a colorless and odorless gas. Once a leak occurs, it is difficult for people to detect it. Therefore, in order to detect the natural gas leak in time, it is necessary to add an odorant with a special odor to the natural gas. In this way, when the natural gas leaks, people can detect it in time by smelling the odorant and take corresponding measures to avoid safety accidents. In addition, the odorization device can also realize the precise control of the concentration of the odorant, improve the odorization efficiency, real-time monitoring and alarm, remote monitoring and management and other functions, providing strong protection for the safe use of natural gas.

[0003] When the existing intelligent odorization device at the end of the natural gas pipeline network is in use, odorant and natural gas leakage may occur. Tetrahydrothiophene is toxic to a certain extent. Long-term exposure of workers in a high concentration environment will have adverse effects on the human body, such as causing headaches, nausea and other symptoms. Therefore, corresponding treatment measures are needed to solve the problem. Utility Model Content

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the present invention proposes an intelligent odorizing device at the end of a natural gas pipeline network, comprising:

[0021] The body 1 is fixedly mounted with a natural gas odorizer body 2 and a purification mechanism, which includes a sensing component, a purification component, and a transmission component. The sensing component includes an electrochemical sensor 3 fixedly mounted on the inner wall of the body 1. The inner wall of the body 1 is fixedly connected to a controller 4. The side wall of the body 1 is fixedly connected to a motor 5 via a bracket. The output end of the motor 5 is fixedly connected to a No. 1 rotating shaft 6, which is rotatably connected to the inner wall of the body 1 via a bearing. The end of the No. 1 rotating shaft 6 away from the motor 5 is fixedly connected to a blower fan blade 7. The electrochemical sensor 3 is electrically connected to the controller 4, and the controller 4 is electrically connected to the motor 5. The electrochemical sensor 3 senses leaked odorant and natural gas and transmits signals to the controller 4. After receiving the signals, the controller 4 controls the motor 5 according to the signals.

[0022] The purification component includes a shell 8 fixedly connected to the inner wall of the body 1, and a No. 2 rotating shaft 9 is provided in the shell 8. The No. 2 rotating shaft 9 is rotatably connected to the side wall of the body 1 through a bearing. A partition 10 is fixedly connected between the inner walls of the shell 8, and a plurality of ventilation holes are equidistantly provided on the side walls of the partition 10. An exhaust fan blade 11 is fixedly connected to one end of the No. 2 rotating shaft 9 close to the partition 10. The transmission component includes a driving wheel 12 circumferentially fixedly connected to the No. 1 rotating shaft 6, and a driven wheel 13 is fixedly connected to the No. 2 rotating shaft 9 circumferentially. A belt 14 is sleeved between the driving wheel 12 and the driven wheel 13. The exhaust fan blade 11 is located in the shell 8. The shell 8 is filled with activated carbon, which is used to absorb leaked odorizer and natural gas. The driving wheel 12 and the driven wheel 13 are both located outside the body 1. The diameter of the driving wheel 12 is larger than the diameter of the driven wheel 13, so that the purification component can operate efficiently.

[0023] The detailed working process of this utility model is as follows:

[0024] When the device is in use, if an odorant or natural gas leak occurs, the electrochemical sensor 3 will sense it. It is based on the electrochemical redox reaction. When the odorant molecules diffuse to the working electrode surface of the electrochemical sensor 3, an oxidation or reduction reaction will occur. This reaction will generate an electric current. The controller 4 will receive the signal from the electrochemical sensor 3 and then send a control instruction to the motor 5, thereby starting the motor 5 and realizing the sensing operation. After the motor 5 is started, it will drive the first shaft 6 to rotate, thereby driving the fan blades 7 to rotate, so that the air in the body 1 is circulated, which is conducive to improving the subsequent purification efficiency.

[0025] The rotation of the No. 1 rotating shaft 6 drives the driving wheel 12 to rotate, and then drives the driven wheel 13 and the No. 2 rotating shaft 9 to rotate through the transmission of the belt 14. The rotation of the No. 2 rotating shaft 9 drives the exhaust fan blades 11 to rotate. The rotating exhaust fan blades 11 will cause the air in the device to flow toward the inside of the shell 8, and then the flowing air drives the odorant and natural gas to flow toward the shell 8. After flowing into the shell 8, they will be directly adsorbed by the activated carbon, thereby realizing the air purification operation without human intervention, safe and efficient.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
