Description
Technical field
The utility model relates to compressed natural gas and adds smelly field, relates in particular to a kind of device for adding odor of high pressure compressed natural gas line.
Background technique
Rock gas is widely used day by day as a kind of clean energy resource.Because its explosion limit is 5%～15%.Therefore, in case leak, will cause catastrophic effect.Because pure rock gas itself is a kind of gas of colorless and odorless, self sense organ of human body extremely difficulty is discovered again.For this reason, before rock gas being supplied with user's use, all will add artificially very responsive odor sensitizer---a kind of chemical product that off-odor is arranged of human body sense of smell in rock gas, typical odor sensitizer is that (its addition is 10～30mg/m to the tetrahydrothiophene that is the colourless liquid state
3, mg/m
3Every cubic metre of expression milligram), to guarantee that people are to the vigilance of natural gas leaking.Usually, rock gas add smelly process all in gaseous state, carry out under the low pressure condition, device for adding odor also all uses in this pressure range.Present device for adding odor includes: be installed in the container with temperature and pressure compensated fax flowmeter, the speed-adjustable motor that inserts tetrahydrothiophene atomization spray cap in the natural gas line, plunger metering pump by delivery pipe and this atomization spray cap UNICOM and this plunger pump thereof and frequency modulator, splendid attire tetrahydrothiophene in the natural gas line, and the programmable controller etc. of controlling fax flowmeter and frequency modulator.
In recent years, along with the day by day increase of rock gas consumption, for storing and convenient transportation, LNG Liquefied natural gas has appearred.And be that (the storage pressure of LNG Liquefied natural gas is 0.049～0.784MPa for the manufacturing process of compressed natural gas for the LNG Liquefied natural gas direct gasification, temperature is-163 ℃, through forced gasification equipment heat absorption Phase Transformation Booster, be converted into the gaseous compressed rock gas of pressure＞20MPa, this process is called for short the liquefied natural gas gasifying manufacturing process; MPa represents MPa), its enforcement that adds smelly operating process is just very difficult.There is no at present adoptable product or modular system, its major technique difficulty is based on following two aspects,
(1) in the liquefied natural gas gasifying manufacturing process, when rock gas is in liquid state, because the solidifying point of tetrahydrothiophene liquid is 96.2 ℃, it will form solid and precipitate in-163 ℃ liquified natural gas, can't be diffused into and realize adding smelly function in the rock gas;
(2) and be in the gasification or behind the gaseous state, its state pressure reaches more than the 20MPa again when rock gas.Therefore, simply aforesaid existing stink adding method and device are improved at present, the input amount of its corresponding technique, Plant reconstruction plant modernization and total equipment thereof is very large.
