Dehydration device for natural gas

Abstract

The invention provides a dehydration device for natural gas. The dehydration device comprises a dehydration part and a drainage part, wherein the dehydration part comprises a first cylinder and a second cylinder, a wet gas inlet is formed in the side wall of the first cylinder, a gas-water guide pipe is arranged in the first cylinder in a penetrating manner, and a gas passing hole communicated with the wet gas inlet penetrates through the side wall of the gas-water guide pipe; the second cylinder is connected above the first cylinder in a sealed manner, a cylindrical water filter film is arranged in the second cylinder, an inner cavity of the water filter film is communicated with the gas-water guide pipe, and a first dry gas outlet is formed in the side wall of the second cylinder; the drainage part comprises a water-gas shunt pipe, the upper end of the water-gas shunt pipe is connected with the lower end of the gas-water guide pipe in a sealed manner, the lower end of the water-gas shunt pipe is connected with an upper valve, a water containing chamber is arranged in the water-gas shunt pipe, and an upper floating ball is arranged at the lower part of the water containing chamber and connected with the upper valve. The water filter film is used for filtering and dehydrating wet natural gas, the defect that dehydration cannot be effectively performed at the high air temperature in the prior art is overcome, and automatic dehydration and automatic drainage are realized around the clock all the year round.

Description

technical field [0001] The invention relates to a dehydration device, in particular to a natural gas dehydration device used for dehydration of self-produced natural gas in an oil production station. Background technique [0002] In the process of oil field development, the natural gas separated from the buffer tank of the oil production station is transported to the water jacket furnace area of ​​the oil production station through the natural gas pipeline network, and is used for the heating furnace, the export furnace, the oil mixing furnace, the water mixing furnace, and the primary heating furnace. For heating gas, if the gas production is greater than the water jacket furnace consumption of the oil production station, the excess will be sent to the external gas transmission trunk line for other uses. Because the natural gas separated by the buffer tank of the oil production station contains a certain amount of water (the buffer tank of the oil production station has no ...
