Description
Technical field
The utility model relates to natural gas impurity elimination apparatus field, specifically a kind of selexol process dust-extraction unit.
Background technique
With the attention that Environmental is protected, oil field heating furnace flue gas emission is required further stringent.In flue gas emission
The high gas of the extent of injury mainly has CO, NOX、SO2Deng these gases, which reach a certain concentration just, will affect human health, makes farming
Object is withered to die.CO and NO in flue gasXEfficient burning equipment can be used in gas and adjustment combustion position is controlled, and SO2Gas contains
Amount control can only be picked up from source (burning), need to remove H in natural gas2The ingredients such as S.Meanwhile when natural gas contains H2When S, combustion
SO is generated after burning2, SO2Convert SO3, SO3It meets steam and becomes H2SO4, to heating furnace tail portion generate corrosion, it is such corrosion oil field repeatly
See it is not fresh, therefore remove heating furnace in H2S is extremely important and necessary.Due to unstripped gas in existing desulfation dust-extraction device
Containing miscellaneous more in body, generally use more piece or multiple desulfurized dust collection columns can be only achieved desulfurization and dedusting in parallel or series after sulfur content reach
It is required that and structure is complicated, take up a large area.
Summary of the invention
In order to solve the above problem, the utility model provides a kind of selexol process dust-extraction unit.
The technical solution of the utility model is: a kind of selexol process dust-extraction unit, including gas-liquid separator, desulfurization and dedusting
Tower, fluid reservoir, gas pipeline are connected with gas-liquid separator entrance, and gas-liquid separator passes through connecting conveying pipe line and desulfurizing tower
It is connected, is connected with coalescing filter in the output end of desulfurized dust collection column, desulfurizing tower is connected by the gas vent that top is arranged
The connection of the entrance of pipeline and coalescing filter, purified natural gas export output, institute by the purifying gas of coalescing filter
Stating coalescing filter is two sections of tower structures, and filter is divided into top filtration section to inside setting filter core supporting plate and bottom settles
Section, filter core supporting plate are provided with venthole, and the snorkel of Coalescence filter core is that detachable close fit is connect with venthole.
Further technical solution, the snorkel of Coalescence filter core are to be threadedly coupled with venthole.
Further technical solution, the Coalescence filter core are multiple, evenly distributed.
Further technical solution, the multilayer Coalescence filter core that Coalescence filter core ecto-entad flows through, is followed successively by filtering from outside to inside
Layer, demulsification layer, coalescing layer.
Further technical solution, coalescing layer are fibrous layer.
The advantages of the utility model and beneficial effect are: adding coalescing filter, gas access at the top of filter core supporting plate
Position, coalescing filter gas vent filter core supporting plate bottom design, in this way be more conducive to natural gas coalescing filter progress
Fine dedusting, dehydration, purification and blowdown.Integrated skid structure is small with occupied area, facilitate operation, be easy to desulfurization
The features such as dedusting agent is replaced, desulfurization dust-removing efficiency is high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of Coalescence filter core；
Wherein: gas-liquid separator 1, desulfurized dust collection column 2, coalescing filter 3, Coalescence filter core 4, fluid reservoir 5, skid platform 6,
Gas inlet 7, connecting conveying pipe line 8, gas outlet 9, filter core supporting plate 10, venthole 11.
Specific embodiment
The utility model is further described with reference to the accompanying drawing: a kind of selexol process dust-extraction unit, skid platform 6
Channel steel base on be arranged gas-liquid separator 1, desulfurized dust collection column 2, coalescing filter 3, fluid reservoir 5.Containing H2S gas pipeline with
The gas inlet 7 of the purifying gas side setting of gas-liquid separator 1 is connected, and gas-liquid separator 1 passes through connecting conveying pipe line 8
It is connected with desulfurized dust collection column 2, the gas pipeline of desulfurization and dedusting of desulfurized dust collection column 2 is connected by the gas vent that top is arranged
Adapter tube line is connect with the entrance of coalescing filter 3, and purified natural gas is exported by the gas outlet 9 of coalescing filter 3,
Gas-liquid separator 1, desulfurized dust collection column 2,3 bottom of coalescing filter connect fluid reservoir 5, the utility model spent material by blowdown pipeline
The Coalescence filter core 4 that ecto-entad flows through, first passes around high-precision filter layer, and solid particle is intercepted, filtered material into
Enter the layer that is demulsified, impurity in material be demulsified, subsequently into coalescing layer, coalescing layer is fibrous layer, the droplet in gas with
Fiber contacts simultaneously adhere to thereon, have been polymerized to biggish water droplet in the joint of fiber, pass through venthole 11 under the effect of gravity,
It is deposited to the bottom of coalescing filter 3.
The gas vent of gas-liquid separator 1 and desulfurized dust collection column 2 is all set in top, gas-liquid separator 1 and desulfurization and dedusting
2 gas access of tower is all set in side position on the lower side, and the sewage draining exit of gas-liquid separator 1 and desulfurized dust collection column 2 is all set in bottom
Portion, the gas access of coalescing filter 3 is in the top position of filter core supporting plate 10, and the gas vent of coalescing filter 3 is in filter core support
The bottom of plate 10 is more conducive to natural gas coalescing filter in this way and carries out fine dedusting, dehydration, purification and blowdown.
