Description
Technical field
The utility model relates to a kind of desanding device, especially a kind of Novel wellhead cyclone desanding device.
Background technology
At present, the oil gas field desanding mostly is several fixedly tank bodies and carries out desanding or desilting, and this mode desanding is very simple, the desanding separating effect is bad, therefore except the oil gas after sand separation, certain grains of sand is still arranged, and this simple mechanism is the one-level desanding, serious, irremovable to the pipeline damage.Continuous increase along with oil field mining liquid, the silt carrying capacity of Produced Liquid is also increasing, although take various sand control measures, but still lose control of this development trend, cause very big harm to whole gathering system, cause pipeline to be amassed the sand plug plug, the resistance of pipeline mill increases, cause pipeline abandonment because washing away, even Oil/gas Well stops production; The gas-liquid of extraction simultaneously seriously can cause the rear pump body to be worn through very soon because taking sand, and valve is damaged, does not therefore understand and has decided the sand problem, is difficult to realize closed gathering, and has had a strong impact on normal production and adopted defeated efficiency.For this problem, oil gas field is all being done a lot of work aspect desanding, sand discharge, from aspects such as well head desanding, large tank settling sand removing, ground oil-gas gathering and transportation system desanding, oil gas field system desanding technology is explored, and pointed out to integrate the research direction of the online Comprehensive Preventing sand preparing system of the functions such as separation, collection, cleaning, dehydration.
The utility model content
The utility model provides a kind of simple in structure, volume is little, desanding efficiency is high Novel wellhead cyclone desanding device.
Realize a kind of Novel wellhead cyclone desanding device of the utility model purpose, comprise cyclone body, on the well head pipeline that install by flange and connector the both sides of described cyclone body; Described cyclone body is connected with adjustable supporting device by the flange of both sides, described cyclone body eccentric orfice is the eccentric disengagement chamber of one-level, rotary fluid mechanism is secondary cyclone separator structure, be provided with orthogonal air inlet pipe and escape pipe in described cyclone body, described air inlet pipe below is provided with rotary fluid, described rotary fluid below is provided with strainer, described strainer below is provided with the rotational flow separation cone, described rotational flow separation vertebra below is provided with the wedge type gate valve, described wedge type gate valve below is provided with sandbox, and described sandbox below is provided with plug valve.

The beneficial effect of a kind of Novel wellhead cyclone desanding device of the present utility model is as follows:
A kind of Novel wellhead cyclone desanding device of the present utility model, basic principle is that eddy flow centrifugal sedimentation separates, and suspended particulate is separated under the centrifugal acceleration effect from gas-liquid.Totally-enclosed in whole operation process, pollution-free, regularly artificial sediment outflow, more be conducive to environmental protection.
Sand is the closer to center of rotation, and its speed is higher, and suffered centrifugal force is larger, and sand grains more easily is thrown toward inwall; Simple in structure, cost is low, be easy to install and operation; There is volume little, process capability of sediment outflow large, save site space; Efficiency is high, and resistance coefficient is little, and inflow-rate of water turbine is large, and sand removal is convenient; The automatic sand removal effect is pretty good, and efficiency is more than 85%.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of Novel wellhead cyclone desanding device of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of Novel wellhead cyclone desanding device of the present utility model, comprise cyclone body 1, on the well head pipeline that install by flange 2 and connector 3 both sides of described cyclone body 1; Described cyclone body 1 is connected with adjustable supporting device 13 by the flange 2 of both sides, described cyclone body eccentric orfice is the eccentric disengagement chamber of one-level, rotary fluid mechanism is secondary cyclone separator structure, be provided with orthogonal air inlet pipe 6 and escape pipe 5 in described cyclone body 1, described air inlet pipe 6 belows are provided with rotary fluid 7, described rotary fluid 7 belows are provided with strainer 8, described strainer 8 belows are provided with rotational flow separation cone 9, described rotational flow separation vertebra 9 belows are provided with wedge type gate valve 10, described wedge type gate valve 10 belows are provided with sandbox 12, and described sandbox 12 belows are provided with plug valve 14.
Described air inlet pipe 6 outsides are provided with protection against erosion sheath 4.
Described cyclone body 1, wedge action valve 10 and sandbox 12 link together by fastening devices, are fixed on adjustable supporting device 13.
The operating principle of a kind of Novel wellhead cyclone desanding device of the present utility model is as follows:
Pipeline carries out oil gas and adopts in defeated process, shake out or go out fracturing sand in the inherent certain phase of a lot of well wells, to the serious or serious blocking pipeline of pipeline damage, this can bring very burden to production, this novel a kind of Novel wellhead cyclone desanding device is installed, can be effectively improved the undesirable condition occurred on pipeline.Separating mechanism sand is that the high speed medium enters main body eccentric orfice inner chamber from connecting entrance, and fluid is separated at the main body inner chamber, and one-level is eccentric separates, and fluid is advanced into rotary fluid mechanism under continuing, and is secondary cyclone separator structure.
The core component of this desanding device is cyclone separator, its operating principle: be that the flow direction that forcibly changing is taken the sand flow body changes eccentric parabolic by form of straight lines, transfer again the vortex form to after entering rotary fluid, this flow direction makes fluid High Rotation Speed in cyclone separator, produces thousands of times to the centrifugal force field of gravitational field.Under centrifugal force and Action of Gravity Field, the sand grains that density is large is got rid of to surrounding, and move downward along inwall, the separated desilting bag that enters; Move upward in the middle of the gas-liquid that density is little or fine particle are brought to, thereby reach gas, sand, the liquid purpose of separation automatically.
The utility model design, mainly for the oil gas field hole condition that shakes out, is carried out Solid-Liquid Separation but also be applicable to other industry, particle or the fluid separation applications of gas phase, liquid phase, solid phase certain limit granularity can be opened.
Embodiment recited above is described preferred embodiment of the present utility model; not scope of the present utility model is limited; design under spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model, all should fall in the definite protection domain of claims of the present utility model.
