Background technique
The comprehensive utilization of gas pressure ability has important economic benefit and social benefit.Utilizing pressurized gas to expand aspect acting compresses low-pressure gas, equipment commonly used has decompressor-compressor bank, turbosupercharger and sparger.Turbine and turbosupercharger rely on impeller to transmit energy, complex structure, and rotational speed is high and be difficult to be with liquid to be operated.Though sparger has no rotating component, characteristics such as simple in structure, its efficient is very low, has only tens percent.
The model utility content
The utility model provides a kind of efficient, slow-speed of revolution and can be with the gas jet supercharging device-axial flow jet wave pressure supercharger of liquid operation.
In the utility model pressurized machine, high pressure directly contacts with low pressure two-way gas, relies on the gas pressure ripple to transmit the energy of pressurized gas pulse expansion work, directly low-pressure gas is compressed, and can obtain the gas of one pressure placed in the middle.Different with conventional jet mixing compression, said process does not have the blending of two-way gas basically, so the jet energy loss is little, and compression efficiency is high.
The utility model provides that a kind of structure is simple relatively, efficient, rotating speed is low, easy to maintenance, can be with liquid operation, big, the adaptable gas jet pressurized machine of medium of treating capacity elasticity; Satisfy under oil, gas-field exploitation and other occasions demand that can efficiently utilize compressed gas pressure.
The technical solution that the utility model is taked is:
The utility model is a kind of dependence pressed gas jet successively, makes non-permanent expansion work and the axial flow jet wave pressure supercharger of supercharging, is mainly connect the rotary drum 9 of frustoconic shape by cylindrical, frustoconic shape or cylinder, rotary drum overcoat 11; Many conduits 10 as the pressure oscillation pipe, main shaft 18, left body 4; Right body 16, shell 12, high-pressure spray nozzle 2; Low pressure gas ejecting port 8, middle extrusion head piece 13 is all pressed mouth 20; High pressure admission mouth 1 and high-pressure buffer chamber 3, low-pressure admission mouth 7 and low pressure buffer chamber 6, middle extrusion gas port 15 and 19 compositions of middle pressure buffer cavity.Inside at rotary drum 9; Circumferential row is furnished with many closed channel 10 as the pressure oscillation pipe, and high-pressure spray nozzle 2 and middle extrusion head piece 13 are static, places the two ends of rotary drum 9 respectively; The radially radial height of the two is aligned in the top opening and the end openings of conduit 10 in the rotary drum 9 respectively.Rotation along with rotary drum 9; High-pressure spray nozzle 2 jet successively in the conduit 10 that circumference is arranged; The gas that produces in the compressional wave compression conduit 10 boosts it; Treat that conduit 10 turns over after the several angle with rotary drum, its end openings circumferentially overlaps with middle extrusion head piece 13, and the gas after boosting is discharged conduit; The top opening of jet rear slot track 10 is owing to turn over high-pressure spray nozzle 2; Promptly by the solid wall shutoff of this nozzle periphery; Opening produces extensional wave and makes this place's pressure reduction at top; When conduit 10 top openings forward to when overlapping with low pressure gas ejecting port 8, low pressure gas is inhaled into conduit 10, repeats above-mentioned jet and compression process then.
The rotation of rotary drum 9 in the utility model pressurized machine just for producing periodic jet, compression, exhaust and air-breathing required, rather than is carried out transformation of energy as turbomachinery, thus its rotating speed do not need very high (＜5000r/min).
In the ring cavity that surrounds between the circle in rotary drum 9 cylindricals and the rotary drum overcoat 11; With many long narrow walls that longitudinally cut off is that 21 pairs of ring cavities of screen carry out circumferential cutting; In ring cavity, form many both ends opens and the conduit 10 of border seal; The axis of conduit 10 becomes certain radial dilatation angle with the axis of rotary drum 9, and also the bus with rotary drum 9 surfaces becomes certain circumferential angle, and the passage section of conduit is that uniform section, variable cross section or uniform section add variable cross section; The flow area of variable cross section; Employing is with the degree of depth, the width of conduit 10; Or the ever-increasing mode of dark, wide size; Direction of flow gradually expansion type in the conduit 10 increases, high-pressure spray nozzle 2 and middle extrusion head piece 13 respectively with the top mouth and the end port radially aligned in pressure oscillation tube seat road 10, and the axis of the two staggers along turning to of rotary drum the circumference angle certain; The middle head piece 13 that extrudes is provided with diffusion fluid director 14 with middle pressure buffer cavity 19 connecting parts, also is provided with the balancing orifice 20 that conduit 10 is communicated with middle pressure buffer cavity 19 on the right body 16.
For making the utility model axial flow jet wave pressure supercharger have higher efficient and adaptability, also adopted following several kinds of structure characteristics:
1. as the conduit 10 of the crucial runner of compression process, its flow area longshore current to weaken the intensity that compressional wave is superimposed as shock wave, improves the isentropity of process to being that expansion gradually or partial-length section are expanded gradually, improves compression efficiency.
2. between middle extrusion head piece 13 and middle pressure buffer cavity 19, diffusion fluid director 14 is set, the harmless lost territory of the kinetic energy of calming the anger in effluenting is changed into the pressure ability.
3. all preferable for the performance that guarantees equipment under the different pressure ratios; Right body 16 is provided with the balancing orifice 20 that conduit 10 is communicated with middle pressure buffer cavity (19); After accomplishing a circulation; If the pressure in the conduit 10 is higher than balancing orifice 20, portion gas is pressed buffer cavity 19 in entering via balancing orifice 20, and the pressure in the conduit is reduced; Vice versa.The basic pressure with middle extrusion head piece 13 of pressure in the conduit 10 is maintained an equal level, avoid, when conduit 10 end openings overlap with middle extrusion head piece 13, produce and disturb pressure wave in next one circulation.
The beneficial effect of the utility model is:
Obtain that a kind of rotating speed is low, structure is simple relatively, energy transfer speed is fast, can be with the liquid operation, can efficiently realize pressure-exchange between two kinds of gases, effectively utilize pressure can new type pressurized equipment.The pressure that the utility model axle general formula jet wave pressure supercharger is suitable between all gases medium can exchange; Utilizing high pressure high gas rate well pressure energy of natural gas to promote the pressure rating of low-voltage and low-yield gas well, make the low-pressure gas well high and stable yields have very big using value.In addition, industrial waste gas pressure can utilize and oil and chemical industry in vacuum evaporation, vacuum purification etc. also be suitable for.
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation.
