Description

Full-automatic air water oil three-phase separating device

Technical field:

The utility model relate to a kind of to containing water or/and the natural gas of fluid carries out the purifier of separating treatment, it is a kind of full-automatic air water oil three-phase separating device.

Background technology:

Needn't doubt, petroleum chemical enterprise gathers the natural gas of producing and contains some water or/and fluid from the gas well of oil field, these water will be or/and fluid will have a strong impact on the quality index of gas product, for improving the purity and the quality grade of gas product, must be with the water that contains in the natural gas or/and fluid carries out the separate discharge purified treatment, petroleum chemical enterprise is provided with dewatering and drainage worker's work position specially in the gas production process, dewatering and drainage worker's main responsibility be exactly all-weather periodically with in the natural gas storage tank constantly the water of sedimentation or/and the fluid discharging is clean, in general, this work mostly is operation in the open air, the working environment dullness is uninteresting, and dewatering and drainage workman's work situation is very arduous.Just present, the work of dewatering and drainage be exactly regularly open the bottom valve of natural gas storage tank with the water of sedimentation or/and fluid directly emits, the workman is only with working experience or rely on perusal and judge to take off to drain and promptly close bottom valve after clean.This original extensive mode of operation, be difficult to guarantee work quality, often occur that natural gas is accompanied by the water that is discharged, oily impurity and a large amount of major accident that leaks not only causes a large amount of wastes of physical resources, but also the severe contamination surrounding enviroment, just in case explosion caused its consequence is with hardly imaginable.This is petroleum chemical enterprise's problem anxious to be solved, also is the technical scheme problem to be solved that the utility model proposes.

The utility model content:

The utility model is based on existing " natural gas drain valve " and the technology of " oil storage tank automatic dehydration device " and propose a kind of oily three-phase separating device of full-automatic air water of going here and there that dress is convenient, reliable, leak resistance is good and automaticity is high; it is specially adapted to containing water or/and the natural gas of fluid carries out the isolation of purified processing; can obviously improve the gas product quality; and be convenient to fluid and collect utilize, improving the worker laboring environment and peripheral ecological protection all has positive effect.It mainly is made of gas-liquid separator that inlet tube, escape pipe, liquid header are installed and the choke drain pump that is fitted with floating drum, tapping valve, it is characterized in that: be equipped with one group in the gas-liquid separator and cross the liquid disperser and separate filter, stop valve and the transfusion inlet tube that is communicated in the choke drain pump are installed on liquid header, form separator by gas-liquid separator and choke drain pump string assembling structure.It is installed and used like this: inlet tube is connected on the gas outlet tube pipeline of the natural gas well, escape pipe is connected on the appendix pipeline of transport gas finished product, the stop valve of closing again on the liquid header makes liquid header gang up mutually with the choke drain pump, mixing the natural gas that has water or fluid will enter in the gas-liquid separator, stop peptizaiton owing to cross the liquid disperser, water that density is bigger or fluid continue to move downward and enter liquid header, in transfusion inlet tube input choke drain pump, and the less natural gas of density moves upward, and passes the pure natural gas via appendix pipeline output that will divide once more when separating filter behind dried up or the fluid.Even also mix the natural gas that minute quantity is arranged in water in the input choke drain pump or the fluid, can be plugged in the top of choke drain pump and send into gas pipeline by muffler.The floating drum of choke drain pump is subjected to the natural gas, water of different densities or different buoyancy that oily medium forms and rises or descending motion, will drive tapping valve unlatching discharge opeing or close choke.So far can realize the purpose that natural gas, water or oil separate.

The utility model also has following technical characterictic:

The tapping valve of above-mentioned said choke drain pump is connected with the feed tube of water and oil separator by drain pipe, equipped water oil dividing plate in water and oil separator, the outlet pipe of water and oil separator is connected with the oil resistance water trap, is made up of gas-liquid separator, choke drain pump, water and oil separator and oil resistance water trap string assembling structure, is applicable to the device that the natural gas that contains water and oil is carried out full-automatic three phase separation.It is the water of discharging when the tapping valve of choke drain pump is opened, oily mixed liquor through carrying out the sedimentation separation of water oil in the drain pipe input water and oil separator, discharge the fluid that separates by the petroleum pipeline that is installed on water oil dividing plate top and reclaim for collecting.Even also mix minute quantity fluid is arranged water body will by outlet pipe enter separate once more in the oil resistance water trap after, by drainpipe will be thoroughly the water of separation discharge.A spot of fluid also can be plugged in oil resistance water trap top closely, will be by separating once more in the water substitution foldback backwater oil eliminator that continues to enter in the oil resistance water trap.Circulation like this can realize natural gas, water, the full-automatic separation of oily three-phase and can collect recycling oil and water resource easily repeatedly.
