Technical Field
The invention relates to the technical field of mechanical devices, in particular to an air-cooled compressor for shale gas recovery.
Background
The shale gas is deep and has the characteristics of self generation and self storage, and the shale is not only a hydrocarbon source rock but also a reservoir rock. Shale gas is one of natural gas but the two concepts are not on one scale. Shale gas refers to natural gas aggregates that reside primarily in dark or high-carbon shale, primarily in adsorbed or free states. In one sense, shale gas reservoir formation is the result of large scale natural gas retention in source rock. The exploitation difficulty of shale gas is relatively large, when the shale gas is exploited for separation or when some shale gas with poor quality is recovered, the components (oil, gas, dark shale, high-carbon shale and other magazines) of the shale gas need to be separated, and an effective compression separation device and a corresponding technical means are still lacked at present.
Patent No. CN201110024537.8 a high rotational speed piston gas compressor, including the crankcase and install the level four cylinder in the crankcase both sides, the level four cylinder links to each other with the crankcase through the midbody, the bent axle has been installed in the crankcase, one-level and second grade cylinder have been installed respectively to one side of crankcase, two three, level four linkage differential cylinders have been installed respectively to the opposite side of crankcase, the bent axle passes through the connecting rod, the cross head links to each other with the piston of the cylinder at each level, its difference lies in every side of bent axle set up a wide crank and two narrow cranks of same phase, narrow crank symmetry is located wide crank both sides to wide crank links to each other through a cylinder piston of wide connecting rod and one side, two narrow cranks of same phase link to each other through a cylinder piston of two narrow connecting. The invention effectively improves the rotating speed of the compressor, can reduce the piston stroke and the cylinder diameter under the condition of the same parameters, greatly reduces the volume and the weight of the compressor, improves the operation efficiency and prolongs the service life.
At present, a cyclone separator and a filter element are generally used for carrying out oil-gas separation on compressor exhaust, the cyclone separator carries out coarse separation on an oil-gas mixture, the separation efficiency of particles with the diameter of 25-50 mu m is more than 98%, and for small particles with the diameter of less than 20 mu m, the filter element is generally used for adsorption and condensation. In the application of process equipment, the cyclone separator has simple and compact structure and low manufacturing and maintenance cost, and has higher separation efficiency than other separation equipment (such as a bag filter, an electrostatic dust collector and the like) in the vicinity of the working point range. Because cyclone adopts the mechanism of inertia separation, its adaptability to the variable operating mode is relatively poor, and when compressor operation operating mode point deviated design operating mode far away, cyclone's separation efficiency will reduce by a wide margin. And a filter element for fine separation is arranged behind the cyclone separator, so that in order to improve the separation efficiency and prolong the service life of the filter element, the oil content of the oil-gas mixture entering the filter element is required to be ensured to be lower than 1000mg/m 3. When the oil injection compressor works, lubricating oil is injected into the oil injection compressor to cool, lubricate and seal the compressor. After being compressed by the rotor, the two-phase mixture of the compressed air and the lubricating oil is separated by the oil-gas separator. In order to improve the quality of compressed air and ensure the safe operation of a compressor, liquid-phase oil drops need to be separated as far as possible, which puts strict requirements on the separation efficiency of an oil-gas separator. The compressor is designed under a rated working condition, but in actual operation, the air inlet and exhaust pressure can change according to actual use requirements, so that the exhaust volume fluctuates. Therefore, the separation efficiency of the oil-gas separator needs to be satisfied in a wide flow range and the whole working condition of the compressor.
The patent No. CN13554593 discloses a combined oil-gas separator and an oil-gas separation method thereof, wherein an inlet initial separation device and an inertia separation area are added on the basis of coarse separation by a cyclone separator and fine separation by a filter element of the traditional oil-gas separator, and a single cyclone in the traditional oil-gas separator is changed into an inner cyclone and an outer cyclone which are nested with each other; a porous thin-wall cylinder for preventing secondary entrainment is arranged in the cylinder body. The inlet primary separation device and the inertia separation area effectively improve the capability of the oil-gas separator to adapt to the variable working condition operation of the compressor; the inner cyclone and the outer cyclone respectively swirl the oil-gas mixture, so that the path length of oil drops which are centrifugally separated to move to the wall surface is reduced, the efficiency of a centrifugal separation section is improved, the separation effect of the filter element is indirectly enhanced, and the service life of the filter element is prolonged; the annular space between the porous thin-wall cylinder and the cylinder body effectively prevents the air flow moving at high speed from impacting the oil film moving downwards along the surface of the cylinder body, and improves the separation efficiency.
However, the prior compression separation equipment has the following disadvantages when in use: 1. the lack of equipment capable of compressing and separating simultaneously or continuously results in low shale gas recycling efficiency and high cost; 2. the sealing of the inside of the compression cylinder of the compression device cannot be ensured, and for dangerous gas such as shale gas, the sealing of the inside of the compression cylinder is ensured, and the safety of the inside is ensured, so improvement is needed; 3. the compression cylinder and the motor of the compression device cannot be radiated, and the radiating effect is poor, so improvement is needed; 4. the filtering effect is poor during oil-gas separation, so that part of vaporized oil is discharged to influence the atmospheric environment; 5. the cylinder is easily exploded due to overlarge pressure in the cylinder body because the pressure in the cylinder body is not detected.
