Abstract
A binocular horizontal separator sacrificial anode protection device is used for the corrosion protection of the binocular horizontal separator of the oil and gas field. A threaded sleeve, upper screw poles and lower screw poles constitute a support column pole. Two support column poles are arranged on the internal wall of the binocular horizontal separator. A rectangular plate is fixed on the lower screw poles. Two lower screw poles pass through both ends of the hole of the rectangular plate respectively. The rectangular plate is fixed between the two nuts. A zinc alloy anode is arranged on the rectangular plate. The invention has the following beneficial effects: the invention chooses to set the anode material and fixed installations as a single entity; the invention has a simple structure and is easy to install; the invention adopts the galvanized threaded sleeve, upper screw poles, lower screw poles and nuts in order to improve the function of corrosion resistance of the device. The effect of corrosion resistance is remarkable so that the life of the binocular horizontal separator is increased and the costs for replacing and maintain the separtor reduce.
Description
Technical field

Background technology
In gas field Natural gas extraction and the defeated process of collection, contain H in the extraction Sweet natural gas
2S and/or CO
2Deng sour gas and contain Cl
-The salinity local water; The Sweet natural gas of extraction carries out in the preliminary gas-liquid separation process in gas gathering station, H
2S and/or CO
2Deng sour gas and contain Cl
-Corrosive mediums such as salinity local water can produce galvanic corrosion to double-tube horizontal separator inwall and annex.At the corrosion of oil-gas field double-tube horizontal separator inside, mainly select for use corrosion resistance nature preferably the above stainless steel (or alloy material) of 22Cr make double-tube horizontal separator or adopt cathode protecting process to realize inhibition.Make double-tube horizontal separator for stainless steel, the price of steel product costliness of strong corrosion resisting property is not suitable for the widespread use in gas field.
At present; to the normal galvanic anode protection method that adopts of the inwall protection of separator; anode material multiselect aluminum alloy anode; but because separator bottom hydrops partially liq complicated component, it is acid or alkaline that water quality might be, and aluminium is amphoteric metal; can be dissolved in acid; also can be dissolved in alkali,, shorten the sacrificial protection time limit so all might quicken the consumption of aluminum alloy anode no matter water quality is acidity or alkalescence.When adopting aluminium alloy to protect the separator inwall as sacrificial anode; multiselect is with board-like circular-arc anode; radially board-like circular-arc anode is fixed in separator cylindrical shell inwall with jackscrew or screw rod along separator then; but consumption along with aluminum alloy anode material; the attenuation of aluminum alloy anode material thickness; jackscrew or screw rod fixed stability and stability descend, and may cause anode material to come off.
The utility model content
The purpose of this utility model is: a kind of double-tube horizontal separator sacrificial anode protection device is provided; can seal head to the oil-gas field liquid collecting and carry out inhibition protection for the double-tube horizontal separator of blind hole type; solving the separator corrosion influences the problem that gas production is produced soon, overcomes the very fast and fixing unstable problem of stationary installation of aluminium alloy sacrificial anode material consumption.
The technical solution adopted in the utility model is: the double-tube horizontal separator sacrificial anode protection device, mainly form by anode, screw shell, last screw rod, following screw rod, nut and rectangular slab, it is characterized in that: there is internal thread at cylinder bodily form screw shell center, be connected with screw rod and following screw rod respectively at the two ends of screw shell, the upper end vertical support of screw rod is on the double-tube horizontal separator inwall; The lower end vertical support of following screw rod is on the double-tube horizontal separator inwall; Screw shell, last screw rod and following screw rod are formed a support post; Two support posts are arranged on the double-tube horizontal separator inwall, and two support posts are in same plane; Be fixed with rectangular slab on the screw rod down, the two ends of rectangular slab are porose, and two following screw rods pass two stomidiums of rectangular slab respectively, on the screw rod two nuts arranged down at each, and rectangular slab is fixed between two nuts; On rectangular slab, be with zinc alloy anode.Anode is suspended in the double-tube horizontal separator securely.
Described anode is a cuboid, and rectangular through holes is arranged on anode, and rectangular slab can pass the through hole on the anode.
Described screw shell, go up screw rod, screw rod and nut are made of copper down, and screw shell, on screw rod, the surface galvanizing of screw rod and nut down.
The beneficial effects of the utility model: the utility model double-tube horizontal separator sacrificial anode protection device, adopted anode material and stationary installation are connected as a single entity, simple in structure, easy for installation; Anode fixation, replacing are conveniently.Adopt galvanized screw shell, last screw rod, following screw rod and nut, improved the corrosion resistance nature of device.Preservative effect is remarkable, improves the work-ing life of double-tube horizontal separator, has reduced the replacing and the maintenance cost of separator.
