Background

Natural gas is a colorless, odorless, flammable and explosive gas, and when the natural gas leaks, in order to be easily found, the natural gas is required to be odorized, and the currently used odorizing agent is tetrahydrothiophene, namely THT, an organic compound or a mixture with a strong odor. When added to gas at very low concentrations, the gas is given a particular unpleasant warning odor so that the leaking gas is perceived when it reaches its lower explosive limit of 5% or a harmful concentration acceptable to humans. Odorizing is generally finished in a unified way at a site and then odorized natural gas is output outwards. The exit inspection standard of the gate station is that the concentration of tetrahydrothiophene is more than or equal to 25 mg/m3. The concentration of tetrahydrothiophene at the rest detection points at the tail ends of all pipelines should meet not less than 15 mg/m3, however, when operation workers carry out community replacement ventilation, the concentration of odorant tetrahydrothiophene from the middle section to the tail end of the vertical pipe of the residential community after valve opening ventilation is only 5-8 mg/m3 and far fails to reach the standard, and the concentration of odorant from the middle section to the tail end of the vertical pipe gradually rises to the standard value after 5-7 days after replacement ventilation of a new pipeline. In order to avoid accidents caused by insufficient odorizing agent concentration in the vacuum period, a device for additionally odorizing a new ventilation pipeline is urgently needed to be researched.
