Application a tail gas processing apparatus of shale gas dehydration sled, the tail gas that produces behind the shale natural gas dehydration by the rectifying column gets into the air cooler separates out water and remaining tail gas through the cooling and gets into divide the fluid reservoir, water via the sewage pipe is arranged to follow-up processing apparatus, remaining tail gas via divide the fluid reservoir to get into arrange outside after the heating furnace burning of reboiler, can effectively eliminate the peculiar smell that exists in the tail gas, the device running cost is low, economic environmental protection, convenient to use, respond well.
Description
Technical Field
The utility model relates to a shale gas exploitation field, especially a shale gas dehydration sled tail gas processing apparatus.
Background
In the exploitation of shale gas, in order to further improve the quality of the exploited natural gas, triethylene glycol dehydration pry is widely used, as shown in fig. 1, tail gas of a distillation column 11 of the triethylene glycol dehydration pry of a shale gas well station has peculiar smell, if the tail gas is directly discharged into the atmosphere through a tail gas discharge pipe 2 of the distillation column, the peculiar smell is diffused to cause environmental protection problems, and if a burning furnace is installed, the investment and the operation cost are increased.
SUMMERY OF THE UTILITY MODEL
The invention of the utility model aims to: triethylene glycol dehydration sled tail gas that uses in the exploitation to the shale gas that prior art exists has the peculiar smell, if directly discharge in the atmosphere, can lead to the peculiar smell to give off and cause the environmental protection problem, if install the burning furnace, can increase investment and running cost's problem, provides a shale gas dehydration sled tail gas processing apparatus.
In order to realize the purpose, the utility model discloses a technical scheme be:
the utility model provides a shale gas dehydration sled tail gas processing apparatus, includes reboiler and the rectifying column that sets up on it, rectifying column intercommunication air cooler, air cooler intercommunication liquid separation jar, liquid separation jar intercommunication the heating furnace of reboiler, be equipped with the sewage pipe on the liquid separation jar.
Adopt a shale gas dehydration sled tail gas processing apparatus, the tail gas that produces behind the shale natural gas dehydration by the rectifying column gets into the air cooler separates out water and remaining tail gas entering through the cooling divide the fluid reservoir, water via the sewage pipe is arranged to follow-up processing apparatus, remaining tail gas via divide the fluid reservoir to get into arrange outside after the heating furnace burning of reboiler, can effectively eliminate the peculiar smell that exists in the tail gas, the device running cost is low, economic environmental protection, convenient to use, respond well.
Preferably, a reboiler fuel gas pipe is connected to the heating furnace of the reboiler.
Preferably, the sewage pipe is connected with a sewage treatment device.
Preferably, the separating tank is communicated with the heating furnace of the reboiler through a separating tank tail gas discharge pipe.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
application a tail gas processing apparatus of shale gas dehydration sled, the tail gas that produces behind the shale natural gas dehydration by the rectifying column gets into the air cooler separates out water and remaining tail gas through the cooling and gets into divide the fluid reservoir, water via the sewage pipe is arranged to follow-up processing apparatus, remaining tail gas via divide the fluid reservoir to get into arrange outside after the heating furnace burning of reboiler, can effectively eliminate the peculiar smell that exists in the tail gas, the device running cost is low, economic environmental protection, convenient to use, respond well.
