TECHNICAL FIELD
[0001] The utility model belongs to natural gas auxiliary device field especially, it relates to a natural gas odorization device. BACKGROUND
[0002] Natural gas is colorless and odorless, and it is difficult to be found if natural gas leaks in the process of daily use and natural gas transmission. In order to enhance the safety of natural gas transmission and use, a certain amount of odorant is usually added in natural gas, which can be found in time when natural gas leaks. The commonly used odorant for natural gas at present is tetrahydrothiophene, which has the advantages of strong odor intensity, stable chemical properties, not easy to corrode pipeline, environmental protection and harmlessness. Tetrahydrothiophene is in liquid state at normal temperature, and the usual adding method is to pass tetrahydrothiophene in the state of separate droplets or fine liquid stream into the gas pipeline, evaporate in the gas pipeline and mix with gas flow. The operation is relatively convenient, and it is widely used. However, this adding method relies on the volatilization of liquid odorant and mixing with natural gas, and the adding amount is affected by the size of natural gas flux. In the time period when the amount of natural gas is small, such as morning, afternoon and night, the amount of liquid odorant passed into natural gas is small, which can be volatilized and mixed in natural gas in time. When the gas peak occurs in the morning, afternoon and evening, the amount of natural gas is large, and it is difficult for a large amount of liquid odorant to be uniformly mixed in natural gas and volatilized in time. The phenomenon of enrichment occurs, and the liquid state is accumulated in the natural gas pipeline. It cannot be mixed into natural gas in a short time, resulting in uneven distribution of odorant in natural gas, and the natural gas in some areas has no odor, which is difficult to play a warning role in leakage, or the local area has strong odor. There is great safety hidden danger. CONTENT OF THE UTILITY MODEL
