Description
Technical field
The utility model belongs to oil gas engineering gas field water treatment technology, especially a kind of sour gas water in field flash drum.
Background technique
Gas water is with the water flooding of sulfur-containing gas extraction, and gas water often dissolves part H2S.Different temperatures with
Under partial pressure, gas phase solute H2S different solubility in liquid phase solvent, the solute H when solvent pressure reduces, in solvent2S will
It promptly parses and releases automatically, form flash distillation.Due to H under high pressure conditions2The solubility of S in water is much higher than sulfur-containing gas
In other components, therefore low pressure flash go out gas be largely H2S, H2S is toxic and mordant gas, is gently then corroded
Pipe-line equipment is heavy then jeopardize personal safety.
Currently, the method that low sour gas water in field flash distillation is mainly flashed using normal pressure or low pressure naturally in both at home and abroad, flashes off
H2S amount is small, low efficiency.Low sulfur-bearing gas-water well is more in eastern Sichuan Basin, produces gas 0.5~5 × 104m3/ d, H2S content 6~
15g/m3.It is flowed directly into Water Tank from the sour gas water in field isolated in natural gas, is generally configured to flow into from the end of tank,
Cesspool is flowed to from the bottom of tank again, is walked by water pump transhipment.The flash distillation of sulfur-bearing gas water in Water Tank, use is exactly normal pressure
Naturally (Water Tank structure diagram is shown in Fig. 1) is flashed.Without atomising device and vaporization plant in Water Tank, flashed vapour leans on decompression nature entirely
It is precipitated, since pressure drop is small, causes to flash insufficient, amount of precipitation is few.Most of H2S remains in sour gas water in field, perishable,
Block pipeline and pressure vessel, increases plant maintenance workload, bring security risk to production run.
Because that cannot be fully sealed, the flashed vapour for causing to drift out is more in downstream wastewater pond, and stink increases, and pollutes air, breaks
Bad environment, there are biggish safe and environment-friendly hidden danger.
Utility model content
The utility model mainly overcomes shortcoming in the prior art, proposes a kind of containing for flash evaporation effect to can be improved
Sulphur gas water flash drum.
The utility model solves technical solution provided by above-mentioned technical problem: a kind of sour gas water in field flash drum, packet
Include blind flange and the cylinder that blind flange lower end is set；
The blind flange is equipped with input duct, and the input duct lower end is equipped with nozzle, and the nozzle is located in cylinder；
Several long slot holes are axially arranged on the cylinder periphery, bottom is equipped with raffinate mouth.
Further, the input duct is bend pipe.
Further, the input duct upper end is equipped with pipe flange.
Further, the blind flange upper end is equipped with lifting lug.
Further, the number of the lifting lug is two, and it is located at the two sides of input duct.
Further, the nozzle is tapered mouth.
Further, the blind flange, input duct, nozzle, cylinder are coaxially disposed.
Further, the cylinder has minor axis section, the long slot hole is evenly arranged on the periphery of minor axis section.
The effect of the utility model is: the utility model structure is simple, improves flash evaporation effect, can efficiently separate and gas field is precipitated
H in water2S ensures the safe transport and processing of sour gas water in field；And with increasing for Water Tank flashed vapour, greatly reduce
Flashed vapour drifts naturally in downstream wastewater pond, is greatly reduced before well station stink ratio, and the peasant of well station side cultivation is also no longer
There is stink in reflection air, downstream technology pipeline and facility are by H2S extent of corrosion mitigates, and safety and environmental protection risk also accordingly subtracts
It is few.
Detailed description of the invention
Fig. 1 is Water Tank structural schematic diagram；
Fig. 2 is the Water Tank structural schematic diagram installed additional after flash drum；
Fig. 3 is the structural schematic diagram of the utility model.
It is as shown in the figure: 1- pipe flange, 2- input duct, 3- lifting lug, 4- blind flange, 5- nozzle, 6- cylinder, 7- elongated slot
Hole, 8- raffinate mouth.
Specific embodiment
Further description is done to the utility model below with reference to embodiment and attached drawing.
As shown in figure 3, a kind of sour gas water in field flash drum of the utility model, including blind flange 4 and setting are in blind flange 4
The cylinder 6 of lower end；Its blind flange 4 be it is discoid, the blind flange 4 be equipped with input duct 2,2 lower end of input duct is set
There is nozzle 5, the nozzle 5 is located in cylinder 6；Several long slot holes 7 are axially arranged on 6 periphery of cylinder, bottom is equipped with residual
Liquid mouth 8.
As shown in Fig. 2, wherein the utility model is in practical application, the utility model is installed at sewage by blind flange 4
On tank, sour gas water in field is through input duct 2, and into flash drum top, at nozzle 5, runner is shunk, and flow rate of liquid increases, and one
Part gas water is precipitated by high speed atomisation, flashed vapour；Another part gas water directly impacts 6 bottom of cylinder, and partially liq is broken,
Fine particles are dissipated into, the flashed vapour of precipitation increases；After being throttled by nozzle 5, the decline of sulfur Gas Fields water pressure is obvious, more conducively dodges
It steams.
From these atomizations, fragmentation, decompression vapour-liquid in point isolated flashed vapour, through the uniformly distributed long slot hole 7 in 6 periphery of cylinder
Top evolution exports together with the flashed vapour being precipitated naturally in tank from Water Tank flashed vapour, after the respiratory siphon discharge of Water Tank
It goes to burn, or makees chemical treatment and sponge, the liquid in cylinder 6 is overflowed through 7 lower part of long slot hole, is flowed in Water Tank；Stop into
When liquid, residual liquid flows in Water Tank through raffinate mouth 8 in cylinder 6.
By the gas field water slug flash drum after 5 reducing pressure by regulating flow of nozzle, makes the liquid atomization, is crushed, point isolated flash distillation
Gas increases, and has achieved the purpose that improve flash evaporation effect.
Wherein input duct 2 can be straight tube or bend pipe, and preferred embodiment is that the input duct 2 is bend pipe, institute
2 upper end of input duct is stated equipped with pipe flange 1.
When its flash drum is mounted on Water Tank, because flash drum volume is larger, need to carry out lifting installation, it is therefore preferable that
Embodiment be that 4 upper end of blind flange is equipped with lifting lug 3, and the number of the lifting lug 3 is two, and is located at inlet tube
The two sides in road 2.It is lifted in this way by two lifting lugs 3, i.e., it is safe and stable.
Nozzle 5 plays reducing pressure by regulating flow in a device, accordingly, it is preferred that embodiment is, the nozzle 5 is taper
Mouth.
In the utility model specifically preferably, the blind flange 4, input duct 2, nozzle 5, cylinder 6 are coaxial
Setting, the cylinder 6 have minor axis section, and the long slot hole 7 is evenly arranged on the periphery of minor axis section.
The above does not impose any limitation on the present invention, although the utility model passed through it is above-mentioned
Embodiment discloses, however is not intended to limit the utility model, any person skilled in the art, practical not departing from
In new technique aspects, is made when the technology contents using the disclosure above and change or be modified to a bit the equivalent of equivalent variations
Embodiment, but all contents without departing from technical solutions of the utility model, according to the technical essence of the utility model to the above reality
Any simple modification, equivalent change and modification made by example are applied, are still within the scope of the technical solutions of the present invention.
