Description

Technical Field

[0001] The present application relates to the field of compressor design and manufacture, and in particular to a radially rotating cylinder liquid piston type reciprocating compressor and a working method thereof. Background Art

[0002] As is known, compressors are divided into two categories according to their working principles: volumetric type and speed type. Among them, volumetric compressors rely on pistons or rotors that move back and forth (reciprocating) or rotate (rotary) in the cylinder to reduce the working volume and increase the gas pressure, which is called a reciprocating compressor or a rotary compressor. At the same time, reciprocating compressors are divided into two categories: reciprocating piston compressors and reciprocating diaphragm compressors. The main advantages of reciprocating piston compressors are wide application pressure range, high efficiency and strong adaptability. However, there are the following defects: 1. The overall size and weight are large; 2. There are many vulnerable parts such as air valves, support rings, piston rings and packings; 3. In order to extend the operating cycle, the compressor cylinder chamber needs to be lubricated with oil, and there is inevitably contamination of the compressed gas by lubricating oil or wear particles; 4. The packing seal cost is high and the reliability is low in high-pressure or leaky gas applications; 5. The compressing high-pressure gas, leaky gas, high-purity gas or rare and precious gas has poor applicability. Although reciprocating diaphragm compressors can avoid such problems, they have shortcomings such as small exhaust flow and short life of key components (diaphragms), which restrict their application development.

[0003] With the emergence of a new material, ionic liquid (a salt composed of organic cations and inorganic or organic anions), the development of traditional reciprocating piston compressors has ushered in a new transformation. Ionic liquids have the advantages of low vapor pressure, low solubility, high decomposition temperature, high thermal stability, high viscosity index and low compressibility, which provide conditions for the innovation of reciprocating piston compressors. The ionic liquid compressor was first proposed by Linde Kryotechnik AG in Germany. Its product features are: the static compressor cylinder is arranged vertically; the power adopts a hydraulic system, and the hydraulically driven piston pushes the ionic liquid to reciprocate up and down in the cylinder. The suction and exhaust compression process of the compressor is completed through the action of the one-way valves at the top of the cylinder inlet and exhaust port. The ionic liquid compressor manufactured by Linde for hydrogen filling stations is much more compact than the standard reciprocating compressor. However, the upper limit of the working frequency of this type of compressor is low, which limits its promotion and application in more fields.

[0004] The patent publication number is CN111365210A, the application publication date is 2020.07.03, and the patent name is: A high-efficiency boosted zero-clearance ionic liquid compressor with precisely adjustable piston stroke; the patent publication number is CN111365211A, and the application publication date is 2020.07.03. A swing-reversing two-stage boosted zero-clearance ionic liquid compressor; the patent publication number is CN111365212A, and the application publication date is 2020.07.03, and the patent name is: A three-stage boosted zero-clearance ionic liquid compressor with real-time adjustable phase difference. Both adopt: the static compressor cylinder is arranged vertically; a hydraulic oil station is used as the power source, and the reversing component is used to switch the hydraulic drive oil circuit. The hydraulically driven solid piston pushes the ionic liquid to reciprocate up and down in the cylinder, and the suction and exhaust compression process of the compressor is completed through the action of the one-way valves at the air inlet and exhaust ports on the top of the cylinder. The above patents face the same problems as Linde's patents. At the same time, because their hydraulic systems use valve control, the system power loss is relatively large and the energy consumption is relatively high.

[0005] The patent publication number is CN101243258A, the application date is 2006.07.25, and the publication (announcement) date is 2008.08.13. The patent name is a pistonless compressor. It proposes a pistonless compressor that is arranged along the axial direction of the inclined disk and rotates along the central axis of the inclined disk. The piston produces a reciprocating motion along the axial direction of the central axis of the rotation and drives the ionic liquid to complete the gas compression in the cylinder. The gas path is opened and closed by the distribution plate. In order to complete the suction process, the compressor needs to be equipped with a pre-boosting screw compressor on the inlet pipeline. The patent uses an ionic liquid piston to independently complete the gas compression process. In terms of operation mode, pump control replaces valve control. The overall structure is more compact and has positive significance in concept; but due to the limitations of the structural design, the pistonless compressor is difficult to meet the application requirements of large displacement. Summary of the invention

[0006] In order to overcome the deficiencies in the background technology, the present application discloses a radially rotating cylinder liquid piston reciprocating compressor having a compact structure, excellent rigidity, balanced power, and flexible control, and a working method thereof.

[0007] In order to achieve the application purpose, this application adopts the following technical solutions:

[0008] A radially rotating cylinder liquid piston type reciprocating compressor, comprising a compressor housing, a compression assembly, a control assembly, a flow regulating device, a cooling circulation system, a gas-liquid processing device, a purge device and a safety protection device; the compression assembly and the control assembly are located inside the compressor housing, and the flow regulating device, the cooling circulation system, the gas-liquid processing device, the purge device and the safety protection device are located outside the compressor housing;

[0026] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0027] 1. The radially rotating cylinder liquid piston reciprocating compressor and the working method thereof described in the present invention have a plurality of cylinder chambers radially distributed along the transmission shaft at the outer edge of the cylinder body, which is conducive to realizing a large-sized cylinder chamber, and the overall structure is compact, which can easily meet the demand of the liquid piston compressor for increasing the exhaust flow rate; the compressed liquid in the cylinder body forms a liquid piston under the action of centrifugal force, eliminating the influence of multiple adverse factors on the liquid piston after the "vertical arrangement of the cylinder" in the prior art, and broadening the application field of the liquid piston reciprocating compressor.

[0028] 2. Compared with the liquid piston compressors in the prior art, the radially rotating cylinder liquid piston reciprocating compressor and its working method described in the present invention adopt a mechanical direct-connected direct-drive working mode for the compressor cylinder, eliminating the hydraulic drive system commonly used in the prior art, simplifying the whole machine matching, and improving the transmission efficiency, so the compressor structure is novel; compared with the traditional reciprocating piston compressor, this machine is a piston-free and air valve-free design, which minimizes the types of vulnerable parts of the piston compressor, extends the life of vulnerable parts, reduces operating costs, and has a long trouble-free operation period.

DETAILED DESCRIPTION

[0039] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments are only specific descriptions of the present invention, and their purpose is to allow those skilled in the art to better understand the technical solution of the present application, and should not be regarded as limiting the present invention.

[0040] Example 1

[0041] like Figures 1 to 5 As shown, the radially rotating cylinder liquid piston reciprocating compressor of the present invention comprises a compressor housing 1, a compression assembly, a control assembly, a flow regulating device, a cooling circulation system, a gas-liquid processing device, a purge device and a safety protection device 19; the compression assembly and the control assembly are located inside the compressor housing 1, and the flow regulating device, the cooling circulation system, the gas-liquid processing device, the purge device and the safety protection device 19 are located outside the compressor housing 1;

[0042] The compression assembly includes a transmission shaft 2, a cylinder body 3, a liquid piston 4, a choke 5, a bearing 6, a retainer 7 and an adjustment cylinder 8; the cylinder body 3 is eccentrically arranged in the adjustment cylinder 8, the transmission shaft 2 is fixed in the center hole of the cylinder body 3, the adjustment cylinder 8 is annular, and an eccentric amount is set between the center of the cylinder body 3 and the geometric center of the adjustment cylinder 8 during assembly; a plurality of mounting holes are evenly distributed radially and radially along the outer edge of the cylinder body 3, and the mounting holes are cylinder chambers 31, compressed liquid, choke 5 and bearings 6 from inside to outside, so that a number of cylinder chambers 31 are formed and distributed radially on the outer edge of the cylinder body 3 along the transmission shaft 2, the choke 5 is connected to the adjustment cylinder 8 and the retainer 7 on the inner wall thereof through the bearing 6, and a through hole 32 is opened in each mounting hole in the cylinder chamber 31 along the axial direction of the cylinder body 3, and the through hole 32 is connected to the control assembly; the transmission shaft 2 is a single-piece integral forging structure, and is rigidly directly connected to the center hole of the cylinder body 3 through a key;

[0043] The cross-sectional area of ​​the flow blocking plug 5 is designed to be equal to that of the liquid piston 4. In some preferred embodiments, the cross-sectional area of ​​the flow blocking plug 5 and that of the liquid piston 4 may be designed to be unequal. At the same time, due to the fluidity of the liquid, the flow passages of the cylinder chamber 31 and the guide hole 32 through which the liquid piston 4 flows are streamlined.

[0044] The working principle of the gas compression cycle in the compression assembly is as follows:

[0045] When the transmission shaft 2 drives the cylinder body 3 to rotate, the inertial centrifugal force generated by the bearing 6, the choke 5 and the compressed liquid, the reaction force applied by the regulating cylinder 8 and the retainer 7, and the gas force of the cyclic pressure change in the cylinder chamber 31 work together, wherein the compressed liquid forms a liquid piston 4 under the action of the inertial centrifugal force; as the cylinder body 3 rotates, with the cooperation of the control assembly, when the liquid piston 4 moves in the direction of the centrifugal force, the volume of the working chamber of the cylinder chamber 31 increases, and the liquid and gas suction processes are completed sequentially; the cylinder body 3 continues to rotate, and the inner wall of the compressor regulating cylinder 8 pushes the bearing 6, the choke 5 and the liquid piston 4 to move toward the rotation center of the cylinder body 3, and the volume of the working chamber of the cylinder chamber 31 decreases, completing the exhaust and liquid discharge processes.

[0046] The liquid piston 4 is formed by using an ionic liquid. The ionic liquid has the characteristics of low vapor pressure, low solubility, high decomposition temperature, high thermal stability, high viscosity index and low compressibility. Therefore, the ionic liquid can block the leakage of the compressed gas. The sealing performance of the ionic liquid can solve the material science problem in the field of high-pressure contact sealing. This embodiment is suitable for the compression of high-pressure gas or gas that is easy to leak, and is also suitable for the compression process of high-purity gas or rare and precious gas. Since the ionic liquid can fully cool the compressed gas, this embodiment can achieve near-isothermal compression and achieve high gas compression efficiency. The ionic liquid can also be used instead of the lubricating medium of the compressor. This embodiment can achieve operation without lubricating oil in the cylinder.

[0047] The liquid piston 4, the flow block 5 and the bearing 6 of the compression assembly rotate at high speed and participate in radial reciprocating motion during the gas compression process. The bearing 6 adopts a sliding bearing type, and the connecting end of the sliding bearing adopts a ball head with a neck structure. The connecting end of the flow block 5 is provided with a U-shaped groove, which can prevent the sliding bearing from turning over. A ball groove is provided at the bottom of the U-shaped groove, and the ball groove is connected to the sliding bearing of the ball head with a neck structure. The sliding end of the sliding bearing forms an arc-shaped sliding matching surface with the inner wall of the adjustment cylinder 8. The retainer 7 is provided at the edge of the annular contact zone formed by the inner wall of the adjustment cylinder 8 and the sliding bearing. The retainer 7 can keep the sliding bearing and the adjustment cylinder 8 in a good contact state at all times, and can also prevent the sliding bearing from turning over; a groove is provided on the matching surface of the sliding end of the sliding bearing, and the axial through hole of the flow block 5 and the axial through hole of the core of the sliding bearing are both connected to the groove opened on the sliding matching surface.

[0048] The relationship between the various forces in the compression assembly is as follows:

[0049] The liquid piston 4 and the choke 5 in the compression assembly generate interaction forces with the regulating cylinder 8 and the retainer 7 on the inner wall thereof through the bearing 6. The typical relationship between the various forces is: when the cylinder body 3 rotates, the liquid piston 4, the choke 5 and the bearing 6 in the cylinder body 3 will generate inertial centrifugal force, and the regulating cylinder 8 and the retainer 7 restrict their movement and exert a reaction force on them. At the same time, the gas with cyclic pressure changes in the cylinder chamber 31 will also exert a gas force on the liquid piston 4, the choke 5 and the bearing 6. Therefore, the force on the liquid piston 4, the choke 5 and the bearing 6 is the gas force and the force on the liquid piston 4, the choke 5 and the bearing 6. The vector superposition of the inertial centrifugal forces of each component; the relationship between the magnitude of the gas force in the cylinder chamber 31 of the compression assembly is: when the cylinder chamber 31 is connected to the intake channel A in the diverter disk 10 and the intake channel 11 in the compressor housing 1, the magnitude of the gas force is equal to the intake pressure; when the cylinder chamber 31 is not connected to the diverter disk 10, the magnitude of the gas force depends on the actual compression state of the gas, and the value is between the intake and exhaust pressures of the compressor; when the cylinder chamber 31 is connected to the exhaust channel B in the diverter disk 10 and the exhaust channel 12 in the compressor housing 1, the magnitude of the gas force is equal to the exhaust pressure.

[0050] As attached Figures 1 to 4As shown, the diverter plate 10 of the control assembly is arranged between the cylinder block 3 and the compressor housing 1, and the diverter plate 10 is installed on the inner wall of the compressor housing 1, and the contact surface of the diverter plate 10 and the cylinder block 3 is tightly fitted; at the same time, three types of channels are provided in the compressor housing 1 and the diverter plate 10, which are respectively used for liquid inlet, air intake and exhaust of the compressor, and these different types of channels are isolated from each other, but for the same type of channels, the channels in the compressor housing 1 and the channels in the diverter plate 10 correspond one to one; further, a liquid inlet channel 13, an air intake channel 11 and an exhaust channel 12 are respectively provided in the compressor housing 1, and three arc grooves are provided on the diverter plate 10 along the circumferential direction, and the arc grooves are provided on the annular surface of the diverter plate 10 corresponding to the guide hole 32, and the arc grooves are provided on the three An air intake channel A, an exhaust channel B and a liquid intake channel C are respectively arranged in each arc groove, wherein the liquid intake channel 13 in the compressor housing 1 is externally connected to the liquid supply pipeline of the cooling circulation system, and is internally connected to the liquid intake channel C in the diverter disk 10; the air intake channel 11 in the compressor housing 1 is externally connected to the gas-liquid mixer 20 through the compressor inlet pipe, and is internally connected to the air intake channel A in the diverter disk 10; the exhaust channel 12 in the compressor housing 1 is externally connected to the gas-liquid separator 14 through the compressor outlet pipe, and is internally connected to the exhaust channel B in the diverter disk 10. When the cylinder body 3 rotates, the cylinder chamber 31 in the cylinder body 3 is cyclically connected to the liquid intake channel C, the air intake channel A and the exhaust channel B in the diverter disk 10 in turn through the conducting hole 32 and the three arc grooves.

[0051] When the cylinder body 3 rotates, the fitting surface between the diverter plate 10 and the cylinder body 3 forms a dynamic and static contact surface, which is perpendicular to the drive shaft 2 of the compressor. At the same time, the contact surface on the cylinder body 3 is the rotating side, and the contact surface on the diverter plate 10 is the stationary side. There is a sealing medium between the dynamic and static contact surfaces, so a dynamic and static sealing surface is formed between the diverter plate 10 and the cylinder body 3, which prevents leakage of gas or liquid.

[0052] The principle of the compression assembly and the control assembly working together is as follows:

[0053] When the cylinder body 3 rotates, as the liquid piston 4 starts to move centrifugally, the working volume of the cylinder chamber 31 also starts to increase. At this time, the arc groove on the diverter plate 10 connected to the liquid inlet channel C, the liquid inlet channel C, and the liquid inlet channel 13 in the compressor housing 1 are connected to the guide hole 32, and the ionic liquid from the cooling circulation system supply pipe begins to be injected into the cylinder chamber 31, and the suction process of the compressor begins; during the suction process, the working volume of the cylinder chamber 31 continues to increase until the guide hole 32 is disconnected from the arc groove, and the suction process ends; the cylinder body 3 continues to rotate, and when the arc groove on the diverter plate 10 connected to the air inlet channel A, the air inlet channel A, and the air inlet channel 11 in the compressor housing 1 are connected to the guide hole 32, the suction process of the compressor begins; as the liquid piston 4 moves centrifugally, the volume of the cylinder chamber 31 continues to increase, and the gas is discharged from the connected air inlet channel 1 1 continues to enter the cylinder chamber 31 until the through hole 32 of the cylinder chamber 31 is disconnected from the circular arc groove, and the suction process ends; as the cylinder body 3 rotates, the liquid piston 4 begins to move centripetally, the working volume of the cylinder chamber 31 begins to decrease, the gas is compressed in the cylinder chamber 31 and the pressure continues to increase, and the pressure increase process continues until the entire gas compression process ends; when the circular arc groove on the diverter plate 10 connected to the exhaust channel B, the exhaust channel B, and the exhaust channel 12 in the compressor housing 1 are connected to the through hole 32, the exhaust and liquid discharge process of the compressor begins, and the gas-liquid mixed phase is continuously discharged from the cylinder chamber 31 through the exhaust channel 12. During this period, the liquid piston 4 continues to move centripetally, and the volume of the cylinder chamber 31 continues to decrease until the through hole 32 of the cylinder chamber 31 is disconnected from the circular arc groove, and the exhaust and liquid discharge process ends; at this time, the compressor will enter the next gas compression cycle.

[0054] The flow regulating device is responsible for the stepless flow regulation of the compressor. By steplessly adjusting the eccentricity between the center of the cylinder body 3 and the geometric center of the regulating cylinder 8, the stroke length of the choke 5 is correspondingly adjusted, thereby completing the stepless regulation of the working volume of the cylinder chamber 31 and the stepless regulation of the flow of the compressor. The flow regulating device is composed of two control pistons on both sides of the regulating cylinder 8 and a hydraulic control unit 9. The two control pistons are respectively located on the opposite sides of the regulating cylinder 8 and are closely connected to the regulating cylinder 8. When the control piston moves, it drives the regulating cylinder 8 to move. The displacement direction of the control piston and the regulating cylinder 8 is in the vertical direction of the transmission shaft 2. The hydraulic control unit 9 adopts an electro-hydraulic controller, which has an electro-hydraulic conversion function. The output oil chamber of the hydraulic control unit 9 is connected to the two control pistons through oil pipes.

[0055] After the hydraulic control unit 9 receives the external control electrical signal, it converts the electro-hydraulic signal to output hydraulic control oil to the two control pistons respectively. The hydraulic control oil pushes the control piston and the adjusting cylinder 8 to synchronously produce horizontal movement. The horizontal movement is perpendicular to the direction of the drive shaft, and the horizontal movement adjusts the eccentricity between the center of the cylinder body 3 and the geometric center of the adjusting cylinder 8. The eccentricity is the main control variable of the flow regulating device. By adjusting the main control variable, the reciprocating stroke length of the liquid piston 4 in the cylinder body 3 can be adjusted accordingly, thereby completing the stepless adjustment of the working volume of the cylinder chamber 31 and completing the stepless adjustment of the compressor flow.
