Abstract
The invention provides a skid-mounted device for dehydrating well-mouth natural gas by using a venturi injecting tube. The skid-mounted device comprises a basal disk, a filter, a cyclone separator, a venturi injecting tube and a buffer cylinder, which are connected in series by a natural gas tube, wherein the basal disk is square-shaped and welded by channel steel and steel plates, and four lifting hooks are arranged on the four corners of the basal disk; the filter, cyclone separator, venturi injecting tube and buffer cylinder are fixed on the basal disk respectively; the cyclone separator is provided with a blow-off valve; and the natural gas tube is provided with a natural gas inlet, a control ball valve, a pressure gauge, a safety valve and a natural gas outlet. The skid-mounted device has the advantages that: the skid-mounting structure adopted in the invention integrates filtration, dehydration, decompression and pressure regulation of the natural gas, the structure is compact and the skid-mounted device can be conveniently moved; and particularly, external energy is not needed, but the water and the gas of the skid-mounted device are separated according to the decompressed dispersion theory of the venturi injecting tube, the processing cost is low, the adaptability is high, and a user can conveniently use the skid-mounted device.
Description
(1) technical field
The present invention relates to the dewatering unit of well head Sweet natural gas, particularly a kind of skid-mounted device that utilizes the Venturi injecting tube to carry out the well head gas dehydration.
(2) background technology
The well head gas dehydration generally has following mode: method of cooling, absorption process.The principle of method of cooling dehydration is, the water content of Sweet natural gas reduces with temperature and reduces when pressure is constant, and this method only is applicable to the roughing out of large quantity of moisture, also is well head gas dehydration method commonly used.Absorption process is meant the method for utilizing hygroscopic material such as triglycol or active solid absorbed moisture, and this method is applicable to deviates from the contained most of moisture of unstripped gas in the large-scale natural gas device.The shortcoming of these two kinds of methods is: first method need consume the very big energy; Second method then needs hygroscopic material and also will add thermal reduction, device complexity, consumes energy, processing costs height.
(3) summary of the invention
The objective of the invention is at above-mentioned existing problems, provide a kind of compact construction, processing costs is low, adaptability is strong, the user the is easy to use Venturi injecting tube that utilizes to carry out the skid-mounted device of well head gas dehydration.
Technical scheme of the present invention:
A kind of skid-mounted device that utilizes the Venturi injecting tube to carry out the well head gas dehydration, comprise chassis, strainer, cyclonic separator, Venturi injecting tube and surge tank and be connected in series by natural gas line, the square chassis of chassis for making with channel-section steel and steel plate welding, four jiaos of the chassis are provided with four Lift hooks, strainer, cyclonic separator, Venturi injecting tube and surge tank are individually fixed on the chassis, cyclonic separator is provided with wash water valve, and natural gas line is provided with Sweet natural gas import, control ball valve, tensimeter, safety valve and gas outlet.
Working process of the present invention: at first the well head Sweet natural gas enters strainer, isolate in the Sweet natural gas solid; Utilize the step-down diffusion principle of Venturi injecting tube, make the well head Sweet natural gas reduce temperature, the water content of Sweet natural gas reduces with temperature and reduces, thereby reaches the effect of gas-water separation.
The scope of application of the present invention is: maximum working pressure 4.0MPa; Gas outlet pressure 1.0-1.5Mpa; Single channel Venturi injecting tube work output 500Nm
3/ h.
Advantage of the present invention is: adopt the skid structure, the filtration, dehydration, decompression, the pressure regulation that integrate the well head Sweet natural gas, compact construction, conveniently moving; Particularly need not provide energy in the external world, but utilize the step-down diffusion principle of Venturi injecting tube to make well head Sweet natural gas gas-water separation, processing costs is low, and adaptability is strong, and the user is easy to use.

(5) embodiment
A kind of skid-mounted device that utilizes the Venturi injecting tube to carry out the well head gas dehydration, comprise chassis 8, strainer 2, cyclonic separator 5, Venturi injecting tube 10 and surge tank 11 also are connected in series by natural gas line 9, the square chassis of chassis 8 for making with channel-section steel and steel plate welding, four jiaos of chassis 8 are provided with four Lift hooks 7, strainer 2, cyclonic separator 5, Venturi injecting tube 10 and surge tank 11 are individually fixed on the chassis 8, cyclonic separator 5 is provided with wash water valve 3, and natural gas line 9 is provided with Sweet natural gas import 1, control ball valve 4, tensimeter 6, safety valve 12 and gas outlet 13.
Among this embodiment, Venturi injecting tube 10 adopts two groups and is parallel on the natural gas line 9, and its inlet diameter is 25mm, nozzle diameter 8.2mm, length 450mm.When intake pressure 4.0MPa, top hole pressure 1.0Mpa, single channel Sweet natural gas work output is 500Nm3/h, detects to show that dehydration rate reaches 98%.
This example structure compactness, non-consumes energy, adaptability are strong, and the user is esy to use, safe and reliable, and is respond well.
