[0042] Reference Figures 1 to 4 As shown, a reciprocating compressor skid provided in this embodiment includes:

[0043] A first base 1, on which a compressor body, a first-level air intake washing tank 11, a first-level air intake buffer tank 10, a first-level exhaust buffer tank 12, a second-level air intake washing tank 14, a second-level air intake buffer tank 13 and a second-level exhaust buffer tank 15 are arranged; the compressor body comprises at least one first-level cylinder 16 and at least one second-level cylinder 17; the air outlet of the first-level air intake washing tank 11 is connected to the air inlet of the first-level air intake buffer tank 10; the first-level air intake buffer tank 10 is provided with at least one first-level outlet, which is connected to the air inlet of the first-level cylinder 16, and the first-level exhaust buffer tank 12 is provided with at least one first-level inlet, which is connected to the air outlet of the first-level cylinder 16; the air outlet of the second-level air intake washing tank 14 is connected to the air inlet of the second-level air intake buffer tank 13, the second-level air intake buffer tank 13 is provided with at least one second-level outlet, which is connected to the air inlet of the second-level cylinder 17, and the second-level exhaust buffer tank 15 is provided with at least one second-level inlet, which is connected to the air outlet of the second-level cylinder 17.

[0044] Specifically, in the present embodiment, three first-stage cylinders 16 and three second-stage cylinders 17 are provided to meet the efficiency of air compression. Correspondingly, three first-stage outlets are provided on the first-stage air intake buffer tank 10, and three first-stage inlets are provided on the first-stage air exhaust buffer tank 12. In other embodiments, four or other numbers can be provided according to actual conditions. The height of the air outlet in the first-stage air intake washing tank 11 is higher than the height of the air inlet to avoid mixing of the inlet and outlet gases, thereby ensuring the stability and storage effect of the gas and the washing effect of the gas. During operation, the gas enters from the air inlet of the first-level air intake washing tank 11, and then enters the first-level air intake buffer tank 10 from its air outlet, and then enters the cylinder through the first-level outlet and the air inlet of the first-level cylinder 16. The compressed gas enters the first-level exhaust buffer tank 12 through the air outlet and the first-level inlet of the first-level cylinder 16 to participate in the next link; in this process, the first-level air intake washing tank 11 is used to wash the gas to a certain extent, so that the particulate impurities in the gas are adsorbed by the liquid when they come into contact with the liquid, thereby cleaning the gas; the first-level air intake buffer tank 10 and the first-level exhaust buffer tank 12 are used to stabilize the pressure fluctuations during the operation of the entire system and ensure the stability of the pressure. The air inlet and outlet process of the second-level cylinder 17 is the same as that of the first-level cylinder 16, and will not be repeated here.

[0045] The second base 2 is provided with a first-stage exhaust cooling front pipeline 50, a first-stage exhaust cooling rear pipeline 51, a second-stage exhaust cooling front pipeline 52 and a second-stage exhaust cooling rear pipeline 53; the air inlet of the first-stage exhaust cooling front pipeline 50 is connected to the air outlet of the first-stage exhaust buffer tank 12, the air outlet of the first-stage exhaust cooling rear pipeline 51 is connected to the air inlet of the second-stage air intake washing tank 14, and the air inlet of the second-stage exhaust cooling front pipeline 52 is connected to the air outlet of the second-stage exhaust buffer tank 15.

[0046] Specifically, the gas coming out of the first-level exhaust buffer tank 12 will be cooled in the subsequent process. Therefore, the gas on the first-level exhaust buffer tank 12 will be connected to the relevant cooling equipment through the first-level exhaust cooling front pipeline 50, and the gas after cooling will be connected to the second-level air intake washing tank 14 through the first-level exhaust cooling rear pipeline 51, so that the gas exhausted from the first-level cylinder 16 will continue to be compressed after the second-level cylinder 17 after certain treatment; similarly, the gas exhausted from the second-level cylinder 17 will also be connected to the relevant cooling equipment through the second-level exhaust cooling front pipeline 52 for cooling.

[0047] The third base 3 is provided with a cooler 6, and the cooler 6 is provided with a first-level air inlet 60, a first-level air outlet 61, a second-level air inlet 62 and a second-level air outlet 63; the air outlet of the first-level exhaust cooling front pipeline 50 is connected to the first-level air inlet 60, the air inlet of the first-level exhaust cooling rear pipeline 51 is connected to the first-level air outlet 61, the air outlet of the second-level exhaust cooling front pipeline 52 is connected to the second-level air inlet 62, and the air inlet of the second-level exhaust cooling rear pipeline 53 is connected to the second-level air outlet 63.

[0048] The relevant setting involved in cooling is a cooler 6, on which a first-level air inlet 60, a first-level air outlet 61, a second-level air inlet 62 and a second-level air outlet 63 are arranged, which are used to make corresponding connections with the first-level exhaust buffer tank 12, the second-level air intake buffer tank 13, and the second-level exhaust buffer tank 15, and finally realize the cooling of the compressed gas.

[0049] Reference Figure 2 As shown, the first base 1 is detachably connected to the second base 2 , and the third base 3 is detachably connected to a side of the second base 2 facing away from the first base 1 .

[0050] The first base 1 is a frame structure to form a support and fixation function for each component on the first base 1. Each component on the first base 1 is fixed accordingly, and the positions of each component remain relatively static, that is, it is a separate sub-skid. During the process of disassembly or transportation, this part can always be carried out separately; the second base 2 is also a frame structure to form a fixation and support for each component on the second base 2, that is, the first-stage exhaust cooling front pipeline 50, the first-stage exhaust cooling rear pipeline 51, the second-stage exhaust cooling front pipeline 52 and the second-stage exhaust cooling rear pipeline 53. The relative positions of each pipeline thereon remain unchanged. At the same time, during the process of disassembly or transportation, the second base 2 and the components thereon can always be carried out separately, and they are another separate sub-skid; a cooler 6 is provided on the third base 3, which is another independent sub-skid; the aforementioned three sub-skids are the most Finally, they can be assembled and installed as a complete skid; the sub-skid formed by the first base 1 and the sub-skid formed by the second base 2 are connected to each other, and the upper components are connected accordingly, and the first base 1 and the second base 2 themselves can be locked by bolts or fixed buckles and fixed calipers to form a whole, and the sub-skid formed by the second base 2 and the sub-skid formed by the third base 3 are connected to each other, thereby finally realizing the indirect connection between the cooler 6 and the components on the first base 1. Similarly, the third base 3 and the second base 2 themselves can be connected by bolts or fixed buckles and fixed calipers, and the disassembly and assembly are quick and convenient, thereby improving the work efficiency; during the connection process, the first base 1, the second base 2, and the third base 3 can be adjusted and moved according to the actual site conditions, thereby providing a certain degree of environmental adaptability.

[0051] The entire reciprocating compressor and related equipment are arranged in separate skids, making the entire compressor very convenient to disassemble and transport. At the same time, some closely related parts of the entire set of equipment are located on the same skid, avoiding the frequent disassembly and assembly of such parts in the future, thereby ensuring the stability of the compressor operation. In addition, the skids can be adjusted to suit different installation environments, thus improving the installation adaptability of the entire reciprocating compressor to a certain extent.

[0052] In some embodiments, the height of the air outlet of the first-level air intake washing tank 11 is higher than the height of the air inlet of the first-level air intake buffer tank 10 ; the height of the air outlet of the second-level air intake washing tank 14 is higher than the height of the air inlet of the second-level air intake buffer tank 13 .

[0053] Specifically, the air outlet of the first-level air intake washing tank 11 and the air inlet of the first-level air intake buffer tank 10, as well as the air outlet of the second-level air intake washing tank 14 and the air inlet of the second-level air intake buffer tank 13 are connected by pipes. In order to avoid the phenomenon of gas backflow, the air outlet of the first-level air intake washing tank 11 is specially set to have a higher height than the air inlet of the first-level air intake buffer tank 10, and the air outlet of the second-level air intake washing tank 14 is higher than the air inlet of the second-level air intake buffer tank 13; in actual conditions, the end of the pipe facing the washing tank is higher than the end facing the air intake buffer tank, and the pipe as a whole is also in an inclined state.

[0054] In some embodiments, a filter 7 is further included, and the air outlet of the secondary exhaust cooling pipeline 53 is connected to the air inlet of the filter 7 .

[0055] After two cycles of compression, the gas that has finally completed cooling will be filtered to ensure the final cleanliness of the compressed gas.

[0056] In some embodiments, a reflux pipeline 8 is also included, wherein the inlet end of the reflux pipeline 8 is connected to the air outlet of the filter 7 , and the outlet end of the reflux pipeline 8 is connected to the air inlet of the primary air intake washing tank 11 .

[0057] The reflux pipeline 8 is used to adjust the total gas output in the entire system. When the downstream gas consumption is small, the reflux amount can be increased, and when the downstream gas consumption is large, the reflux amount can be reduced. In addition, the reflux pipeline 8 can also play a certain balancing role in the gas pressure in the entire system to protect the safe operation of the equipment.

[0058] In some embodiments, an air intake pipeline 110 is also included, one end of which is connected to the air inlet of the first-stage air intake washing tank 11 , and the other end is connected to the air source; the outlet end of the reflux pipeline 8 is connected to the air intake pipeline 110 .

[0059] Specifically, the air intake pipeline 110 is used to supply air to the entire system, and at the same time, the outlet end of the return pipeline 8 is directly connected to the air intake pipeline 110, thereby realizing an indirect connection with the first-level air intake scrubber tank 11.

[0060] In some embodiments, the reflux pipeline 8 includes a manual regulating pipeline 80 , a first automatic regulating pipeline 81 and a second automatic regulating pipeline 82 , and the manual regulating pipeline 80 , the first automatic regulating pipeline 81 and the second automatic regulating pipeline 82 are arranged in parallel.

[0061] In the return pipeline 8, a manual regulating pipeline 80, a first automatic regulating pipeline 81 and a second automatic regulating pipeline 82 are arranged in parallel. When the entire reciprocating compressor is started, the first automatic regulating pipeline 81 and the second automatic regulating circuit are both in an open state, so that all the gas in the system can flow back, avoiding the generation of a large pressure inside the entire system when starting, thereby reducing the load at startup. When the startup is completed, any one of the first automatic regulating pipeline 81 and the second automatic regulating circuit will be in a closed state, and the other will be adjusted according to the actual downstream situation; the manual regulating pipeline 80 is mainly used as a backup when the automatic regulating circuit fails.

[0062] In some embodiments, a venting pipeline 9 is also included, one end of which is connected to the reflux pipeline 8, and the other end is connected to the venting collection pipeline 92; the venting pipeline 9 includes an automatic venting branch 90 and a manual venting branch 91, and the automatic venting branch 90 and the manual venting branch 91 are arranged in parallel.

[0063] The venting pipeline 9 is used to vent the gas in the entire system so as to automatically discharge the gas in the entire system into the flare network when the unit is shut down, thereby reducing the surge of the unit.

[0064] The manual venting branch 91 is used when the automatic venting pipeline 9 fails.

[0065] In some embodiments, it also includes: a first bracket 160, the bottom of the first bracket 160 is connected to the first base 1, the top of the first bracket 160 is connected to the first-level cylinder 16, the first-level exhaust buffer tank 12 is located on the side of the first-level cylinder 16 facing the first base 1, and the first-level air intake buffer tank 10 is located on the side of the first-level cylinder 16 facing away from the first base 1; a second bracket 170, the bottom of the second bracket 170 is connected to the first base 1, the top of the second bracket 170 is connected to the second-level cylinder 17, the second-level exhaust buffer tank 15 is located on the side of the second-level cylinder 17 facing the first base 1, and the second-level air intake buffer tank 13 is located on the side of the second-level cylinder 17 facing away from the first base 1.

[0066] In actual situations, since the air inlet and outlet of the first-stage cylinder 16 are respectively located above and below the first-stage cylinder 16, in order to reserve positions for the air inlet and outlet and at the same time provide a certain support for the first-stage cylinder 16, a first base 1 is provided on the first base 1. The first base 1 adopts a frame structure, and space is reserved in the middle for setting up other components; thereby increasing the compactness of the layout of the entire reciprocating compressor accessories.

[0067] The second bracket 170 corresponding to the secondary cylinder 17 has the same structural principle as the second bracket 170 corresponding to the primary cylinder 16, which will not be described again here.

[0068] In some embodiments, the compressor body includes a motor 40 and a crankcase 41; one end of the crankcase 41 is connected to the side of the motor 40 facing away from the third base 3; on the horizontal plane, the first-stage cylinder 16 and the second-stage cylinder 17 are respectively located on both sides of the crankcase 41; the length direction of the tank body of the first-stage air intake buffer tank 10, the first-stage exhaust buffer tank 12, the second-stage air intake buffer tank 13, and the second-stage exhaust buffer tank 15 are the same as the length direction of the crankcase 41.

[0069] In order to make the layout of the entire reciprocating compressor and its accessory components more compact, the first-stage air intake buffer tank 10, the first-stage exhaust buffer tank 12, the second-stage air intake buffer tank 13, and the second-stage exhaust buffer tank 15 are particularly arranged in a manner consistent with the length direction of the crankcase 41. At the same time, the first-stage air intake buffer tank 10 is located above the three first-stage cylinders 16, the first-stage exhaust buffer tank 12 is located below the three first-stage cylinders 16, that is, in the space reserved inside the first bracket 160, the second-stage air intake buffer tank 13 is located above the three second-stage cylinders 17, and the second-stage exhaust buffer tank 15 is located below the three second-stage cylinders 17, that is, in the space reserved inside the second bracket. Therefore, the layout is reasonably made according to the actual structure of each component, and the layout of the entire reciprocating compressor is guaranteed to be more compact under the premise of normal operation of each function.

[0070] In some embodiments, a support frame 180 is provided on the first base 1, and the support frame 180 is located at the end of the crankcase 41 facing away from the motor 40; a high-level oil tank 18 is provided on the support frame 180, and the oil outlet of the high-level oil tank 18 is higher than the oil replenishing port in the compressor body.

[0071] The high-position oil tank 18 on the support frame 180 is used to replenish oil into the compressor body so as to provide a certain lubrication protection effect during emergency shutdown.

[0072] In some embodiments, an MCC control cabinet 19 and a PLC control cabinet 190 are also provided on the first base 1 for controlling the automation control of the entire working process of the reciprocating compressor, such as the opening and closing of each automatic valve and the starting and stopping of the primary motor 40.

[0073] A first-level exhaust cooling front pipeline 50, a first-level exhaust cooling rear pipeline 51, a second-level exhaust cooling front pipeline 52, a second-level exhaust cooling rear pipeline 53 and corresponding intake and exhaust pipelines are provided on the intake pipeline 110 and the second base 2, and corresponding safety valves 500 are provided to protect the entire system from overpressure. At the same time, relevant pressure and temperature detectors are also provided to monitor the internal pressure and temperature of the pipeline during operation.
