Description
Technical field
The utility model relates to a kind of Sweet natural gas waste water three-phase flow tripping device, belongs to chemical machinery field.
Background technology
Sweet natural gas can produce a large amount of waste water in recovery process, mainly contains the environmental pollutant such as petroleum-type, organic matter, heavy metal, soda acid thing, chlorion in this class waste water, if directly discharge and can cause very big pollution to wellblock periphery.At present, for the improvement of Sweet natural gas waste water mainly for petroleum-type, organic matter, heavy metal and soda acid thing, the clear water-reducible method of the general employing of chlorion for high density is processed, but the method has not only been wasted a large amount of water resourcess, and do not recycle the chlorion in waste water, uneconomical environmental protection.For the Sweet natural gas waste water that contains high-concentration chlorine ion after processing, can adopt the method for evaporative crystallization concentrating and desalinating to recycle the chlorion in waste water, but there is no at present tripping device for Sweet natural gas wastewater treatment, Sweet natural gas waste water treatment cannot implement device maximization be produced processing.
Utility model content
The purpose of this utility model is just for the deficiencies in the prior art, and a kind of Sweet natural gas waste water three-phase flow tripping device is provided.
To achieve these goals, the technical solution adopted in the utility model is such:
A kind of Sweet natural gas waste water three-phase flow tripping device, comprise by circulation tube and be linked in sequence and form recycle pump, heating chamber, separator and the equipment for separating liquid from solid of circulating system, described circulation tube comprises upper circular tube and lower circulation tube, described separator is divided into upper cone section, straight section and lower cone section, lower cone section outlet connects solid collector, described upper circular tube connects separator straight section, and lower circulation tube connects separator lower cone section.Described solid collector comprises gathering barrel, and gathering barrel bottom is provided with top water pipe and accidental discharge pipe, and lower end is provided with drainage conduit.The current of the inner logical certain flow rate of top water pipe make gathering barrel internal flow state, drive the particle flow that is deposited in bottom to discharge from drainage conduit.
Recycle pump is squeezed into preheating in heating chamber by pending waste water, then by upper circular tube, enter crystallization in separator, due to the difference of weight, isolated steam rising to separator upper cone section enters next process, the macrobead of crystallization and the feed liquid of liquid mixing drop into carries out solid-liquid separation in solid collector and obtains crystalline particle, crystallization small-particle feed liquid enters the initial gross separation in equipment for separating liquid from solid of lower circulation tube, clear liquid enters next process, crystallization small-particle is again brought into and in separator, is carried out evaporative crystallization until obtain the crystallization macrobead of designated size and separate by circulation tube.
From energy-saving and cost-reducing angle, wastewater treatment three-phase flow tripping device can be set to multistage use, the heating chamber that upper level tripping device steam out enters into next stage tripping device is used as thermal source, and the vapor condensation of final stage tripping device is that recirculated water is used.
Because entrainment with steam out in separator the liquid foam that contains chlorion, if be directly discharged to next stage heating chamber, use, not only affect heat-transfer effect, also can corrode heating chamber simultaneously.In the separator of final stage tripping device, because gas velocity is larger, the phenomenon of entrainment with steam liquid foam is even more serious, has had a strong impact on the quality of recirculated water, has increased outer row's amount of chloride ions, contaminate environment.For above-mentioned deficiency, as further improvement of the utility model, described separator upper cone section is provided with gas-liquid separation device, and described gas-liquid separation device comprises wire mesh mist eliminator and wash tub pipe, wire mesh mist eliminator is arranged on wash tub pipe top, and wash tub pipe is provided with several nozzles.Because the silk screen on wire mesh mist eliminator can make steam, pass through, liquid foam stops on silk screen, thereby steam is separation with liquid foam, and the steam that obtains more cleaning has improved the quality of recirculated water, has reduced outer row's amount of chloride ions, has reduced the pollution to environment.Wire mesh mist eliminator is rinsed in wash tub pipe timing, prevents that liquid foam from stopping up wire mesh mist eliminator, guarantees the separating effect of wire mesh mist eliminator separate vapour and liquid foam.
Described equipment for separating liquid from solid comprises separator cartridge, chuck and clear liquid vent pipe, and separator cartridge is arranged on lower circulation tube inside, and chuck is sheathed on separator cartridge outside and is connected with lower circulation tube, and clear liquid vent pipe is arranged on chuck top.When the feed liquid that has certain solid-to-liquid ratio enters after separator cartridge from lower circulation tube, feed liquid, in decline process, is filled rapidly chuck, when reaching certainweight, and solid particles sediment.Because the density of solid particulate is greater than liquid, lift velocity is slow, clear liquid more early arrives clear liquid vent pipe and discharges in chuck, due to the area difference of the gap existence between chuck and separator cartridge, solid particulate settles down to reach settled weight when not reaching clear liquid vent pipe, has just realized and so forth the separation of solid particulate and clear liquid.
In order to improve isolated solid particulate purity in solid collector, the solid that assurance is separated reaches product requirement, in described solid collector inside, be provided with solid flotation unit, described solid flotation unit is the water inlet pipe that is arranged on gathering barrel inside, and the water inlet pipe exit end mouth of pipe arranges downwards.According to the density difference of impurity, particle, by water inlet pipe being set at gathering barrel different positions, make the liquid level of different positions be fluidized state, thereby make the impurity that weight is lighter swim in liquid level, heavier particles settling to the drainage conduit of weight is discharged.
The utility model preheating hot feed liquid later enters separator from separator straight section, vaporization rate is fast, in separator, the control of feed liquid liquid level is lower, liquid column hydrostatic pressure loss is little, feed liquid fluctuation is little, vapor zone foam phenomenon is light, and feed liquid starts vaporization above liquid level simultaneously, and gases affect is less than Level Detection in tank.
The utility model three-phase flow tripping device is simple in structure, easy to use, and equipment energy consumption is low, and process range is wide, has realized the maximization industrial scale of Sweet natural gas wastewater treatment equipment and the recycle of Sweet natural gas waste water, has higher environmental protection and economic worth.
