Description

Technical Field

[0001] The invention relates to the technical field of natural gas protection, and in particular to a deodorization system for gas odorizing equipment. Background Art

[0002] Gas odorization, as the name suggests, is to add gas odorizers to the natural gas inside the gas pipeline. Because natural gas is colorless and odorless, leaks are not easy to detect, so odorants must be added to the natural gas so that people can detect gas leaks in time when they occur.

[0003] The gas odorizing device / equipment controls the odorant to enter the interior of the gas pipeline through the switch valve, and the odorant needs to be added to the interior of the natural gas in small quantities and multiple times. Therefore, the staff is required to frequently rotate the switch valve to open and close it, resulting in a large workload for the staff, who will quickly enter a state of fatigue, affecting the work process. Moreover, since each switch valve has a certain maximum number of rotations, that is, the service life of the switch valve, when the switch valve is about to reach its service life, its own sealing performance will be greatly reduced, and it will gradually leak liquid and gas when it is turned to open. The odorizer has an unpleasant odor. Although such an odor will not cause harm to the human body, it will greatly affect the working environment, distract the operator's attention, and easily cause mistakes at work, resulting in a significant reduction in work efficiency.

[0004] When a leak occurs, it is usually not discovered immediately. Only when someone smells the odor can they go to check it. In addition, there is no automatic deodorization, and manual deodorization is required, and the deodorization efficiency is low. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a deodorization system for gas odorizing equipment, which can effectively reduce the impact of accidental leakage and large-scale volatilization of odorants on environmental safety, thereby greatly reducing the possibility of accidents caused by odorant leakage, and no artificial deodorization is required, thus solving the problems mentioned in the above background technology.
