Description

Technical Field

[0001] This utility model relates to the field of natural gas treatment technology, and in particular to an odorant injection pump for natural gas treatment. Background Technology

[0002] Natural gas is a colorless, odorless, flammable, and explosive gas. In order to make it easier for people to detect natural gas leaks, it is required to odorize the natural gas. Odorants are organic compounds or mixtures with strong odors. When odorants are added to the gas at a very low concentration, they give the gas a special, unpleasant warning odor so that the leaked gas can be detected when it reaches its lower explosive limit of 5% or a concentration that is permissible to humans.

[0003] Application No. 202121550805.5 discloses a gas odorization device, including a fixed mounting base plate, a storage device support frame, a storage device, a metering dosing pump, a natural gas inlet pipe, a natural gas outlet pipe after odorization, a metering dosing pump fixing bracket, and a pipe fixing bracket. This utility model uses a tetrahydrothiophene mixture as an odorant. Compared with other odorants, the tetrahydrothiophene mixture has advantages such as strong antioxidant properties, stable chemical properties, long odor retention time, no residue after combustion, low addition amount, and low corrosivity. By setting a pressure gauge, the internal pressure of the tetrahydrothiophene mixture storage tank can be observed in real time. One end of the level gauge is fixedly installed on the top of the tetrahydrothiophene mixture storage tank, and the other end is fixedly installed on the bottom of the tetrahydrothiophene mixture storage tank to observe the storage amount of tetrahydrothiophene mixture inside the storage tank. The overall stability of the tetrahydrothiophene mixture storage tank can be improved by using reinforced support ribs.

[0004] The pump body structure described above is a fixed structure that cannot be adjusted in height, and the injection pipe of the pump body cannot be adjusted at multiple angles. This makes it inconvenient to adjust during odor addition and results in excessively long odor addition time. Utility Model Content
