Abstract

The utility model relates to a spiral high-pressure steam-water separating device used for the steam injection mining system of a thick oil field or other high-pressure steam-water separating systems, composed of a case body 1, a spiral separating head 2, a splash-proof element 3, and a base 4. The dryness of saturated steam produced by a steam injection boiler can be improved by more than 95%, and accordingly, the dryness of the steam injected into an oil layer and even the well yield can be notably improved. Simultaneously, the saturated water separated by the separating device can be used as heating medium to carry out heat exchange, and accordingly, large quantity of energy can be saved. The device has easy production and safe operation, and is suitable for the steam injection mining technology of the thick oil or the high-pressure steam-water separating system.

Description

Spiral high-pressure vapour-water seperator

The utility model relates to a kind of novel separation equipment---spiral high-pressure stream-water separator that is used for viscous crude field exploitation via steam injection system or other high pressure carbonated drink piece-rate system.

Steam-water separator is thickened oil steam-stimulated or the key equipment of steam drive oil production steam injection technology.In common steam process production technology, used steam all is to be 80% saturated vapor by the mass dryness fraction that steam boiler produces, and is injected into pit shaft by pipeline, enters oil reservoir, to improve oil well output and oil recovery.Yet, because thermodynamic loss on the way makes the steam quality that arrives the shaft bottom reduce greatly, thereby influences the oil recovery effect.

Task of the present utility model is to provide a kind of spiral high-pressure stream-water separator, utilizes it the saturated vapor dryness that injection boiler produced can be brought up to more than 95%, thereby the steam quality and even the oil well output that inject oil reservoir are significantly increased.Simultaneously, can be used as heating agent by the isolated saturation water of this separator and carry out heat exchange, thereby save a large amount of energy.

The utility model is achieved in that it is made up of housing 1, spiral separation 2, splashproof element 3 and base 4.Its assembled relation and architectural feature are as follows: spiral separation 2, splashproof element 3 place respectively in the housing 1, wherein, the former and the welding of housing 1 top, its underpart is by the angle steel supporting that is welded on the housing 1, and the latter then is welded in housing 1 middle part by connecting plate; Base 4 is welded on housing 1 below by its skirt body portion, and its chassis portion then links to each other with the skid chassis.During use, this separator is installed in after the steam boiler, after the saturated vapor that is produced by steam boiler enters this separator, through the tangential at a high speed rotation of the first-class element of spiral separation, utilize the liquid steam-operating can be poor, make that liquid phase is settled down to the liquid storage section through a minute liquid film tube along wall in the steam, vapour phase then rises to the top through the centre pilot tube and discharges, thereby reaches the purpose that improves mass dryness fraction.

The utlity model has good separating effect, utilize it can increase substantially the mass dryness fraction of saturated vapor, improve heavy oil wells and annotate the vapour effect, reach energy-conservation purpose simultaneously.This device is easy to make, safe and reliable to operation, is applicable in heavy oil steam injection recovery technology and uses.

Below in conjunction with accompanying drawing enforcement of the present utility model is described further.

In the utility model, housing 1 top, bottom all are hemispherical, and the center has steam drain and leakage fluid dram, and the middle cylinder upper and lower part is left air intake and discharge outlet respectively, and a side is provided with liquid level gauge; A spiral separation 2(sees Fig. 4) constitute by overhead gage 5, centre pilot tube 6, channel partition 7, branch liquid film tube 8 and cloth liquid awl 9.Wherein, overhead gage 5 is circular, and its outer edge is welded with centre pilot tube 6 and shell separator 1 respectively; Centre pilot tube 6 is made by seamless steel pipe, bottom and 9 welding of cloth liquid awl; Channel partition 7 is shape in the shape of a spiral, and its inner rim is welded on the centre pilot tube 6; Divide liquid film tube 8 to make tubular by roll of steel plate, have the ligule slit on the tube, end face welds with annular overhead gage 5; Cloth liquid awl 9 is inverted bell mouth shape, makes with steel plate.Splashproof element 3(sees Fig. 5) constitute by last guide cylinder 10, transition-cone 11 and following guide cylinder 12, upper and lower guide cylinder 10,12 is cylinder, doffing 12 diameters are greater than top cylinder 10, being the transition-cone 11 of being inverted bell mouth shape places therebetween, the three all rolls to form then with steel plate and is welded as a whole, and is welded in housing 1 middle part by connecting plate.Base 4 has the eyelet that is used for penetrating bolt by being octagonal chassis and skirt body two parts are welded on 8 angles on chassis.
