Description

Technical Field

[0001] The present application relates to the technical field of compressor pressure stabilizing devices, and in particular to a compressor intake pressure stabilizing device. Background Art

[0002] A compressor is a mechanical device that compresses gas to increase its pressure, converting mechanical energy into gas pressure energy by reducing the volume of the gas or increasing the kinetic energy of the gas molecules.

[0003] During compressor operation, intake air stability plays a decisive role in its performance and service life. The gases entering the compressor are diverse, and external factors such as temperature and humidity can affect the compressor's operational stability. When moisture enters the compressor, a drainage and gas recovery process is required to remove the moisture. When used in areas with large temperature differences between day and night, the water removed from the moisture can easily freeze and clog the drainage equipment, requiring frequent equipment switching and causing instantaneous pressure increases within the compressor. If timely adjustments are not made, the compressor unit will alarm and shut down due to excessive transient intake air pressure, directly impacting the station's production output.

[0004] Currently, every time a switchgear operation is performed, station maintenance personnel are required to manually control the intake pressure of the compressor unit to ensure its safe and stable operation. This operation is not only frequent but also lasts for a long time.

[0005] With respect to the above-mentioned related technologies, the inventor believes that there is a defect that it is time-consuming and labor-intensive to adjust the air pressure at the air inlet end of the compressor. Summary of the Invention

[0006] In order to solve the above technical problems, the present application provides a compressor intake pressure stabilizing device.

[0007] The present application provides a compressor intake pressure stabilizing device, which adopts the following technical solution: A compressor air intake pressure stabilizing device includes a compressor having an air intake; the compressor air intake pressure stabilizing device further includes: an air inlet pipe, wherein an air outlet end of the air inlet pipe is connected to the air inlet; A regulating component is provided on the air intake pipe and is located at the air intake port; the regulating component has the freedom to move radially along the air intake pipe, and is used to open and close the air intake port; a venturi tube, coaxially disposed in the air intake duct; a first flow monitor, disposed at the air inlet end of the air inlet pipe; a second flow monitor, disposed between the regulating assembly and the air inlet; The central control module is electrically connected to the first flow monitor, the second flow monitor and the power source of the regulating component respectively.

[0008] By adopting the above technical solution, a Venturi tube is set in the air intake pipe. The Venturi tube can optimize the flow state of the gas, so that the complex gas flowing into the air intake pipe is gathered, and then dispersed through the curved side wall of the Venturi tube, so that the gas enters the regulating component evenly, and the gas is stably and continuously supplied to the compressor; the amount of gas entering the compressor is adjusted by the regulating component to maintain a reasonable amount of gas entering the compressor; the air pressure before entering the air intake pipe and the air pressure after regulation are respectively detected by the first flow monitor and the second flow monitor, and the gas data before and after regulation are compared, and the regulating component is timely controlled by the central control module to regulate the amount of gas entering the compressor, so as to avoid excessive changes in the air pressure in the compressor and improve the service life of the equipment.

[0009] Preferably, the air intake duct is connected to a diversion duct; one end of the separation duct is connected to the air intake end of the air intake duct, and the other end is connected to the regulating component; sealing members are respectively provided on both ends of the air intake duct for sliding.

[0010] By adopting the above technical solution, a diverter pipe is set between the air intake pipe and the control component, and seals are set at both ends of the diverter pipe. When the pressure in the air intake pipe is too high, part of the gas can enter the diverter pipe, thereby avoiding excessive pressure in the air intake pipe, reducing the working pressure of the Venturi tube, and providing sufficient time for air pressure control in the air intake pipe.

[0011] Preferably, a buffer component is provided in the diversion pipe; the buffer component comprises: A rotating shaft, coaxially rotatably disposed in the diversion pipe; Multiple guide plates; one end of the guide plate is fixed on the side wall of the rotating shaft, and the other end is in contact with the inner wall of the diversion pipe; multiple guide plates are evenly distributed along the circumference of the rotating shaft; and an air inlet channel is formed between adjacent guide plates.

[0012] By adopting the above technical solution, a rotating shaft is set in the diversion pipe, and a plurality of first spiral guide vanes are set on the rotating shaft, so that the gas entering the diversion pipe can push the first spiral guide vanes and drive the rotating shaft to rotate, so that part of the gas pressure is converted into kinetic energy of the rotating shaft rotation, thereby reducing the gas pressure; and then the flow direction of the gas is adjusted by the plurality of first spiral guide vanes, and divided into multiple air flows, so that the air flow is regularly dispersed, further reducing the gas pressure, making the air flow entering the regulating component smooth, and reducing the working pressure of the regulating component.

[0013] Preferably, the buffer assembly further includes: Two buffer bins are symmetrically arranged on the rotating shaft; the buffer bins are provided with an air inlet and an air outlet; A sealing plate is rotatably disposed in the buffer chamber; the sealing plate covers the air inlet and the air outlet; The sealing plate has a first state for closing the air inlet and a second state for closing the air outlet.

[0014] By adopting the above technical solution, two buffer bins are set in the diversion pipe, so that the air pressure generated after the gas enters the buffer bin is reduced; by setting a sealing plate in the buffer bin, when working, the two sealing plates are in the first state and the second state respectively, so that the two buffer bins work alternately, so that the gas entering the separation pipe flows out in batches, shortening the time for the air flow to enter the regulating component, and cooperating with the rotating shaft and the first spiral guide vane to achieve the effect of graded regulation of air pressure, thereby improving the efficiency of air pressure regulation.

[0015] Preferably, the buffer bin is hemispherical; the outer side wall of the buffer bin is in contact with the side wall of the diversion pipe; the sealing plate is an arc-shaped plate; and the sealing plate is in contact with the inner wall of the buffer bin.

[0016] By adopting the above technical solution, the hemispherical buffer bin can fit tightly with the side wall of the separation pipe, with a good sealing effect, allowing the gas to fully enter the buffer bin; after the arc plate rotates, it is convenient to seal the air inlet or outlet, thereby improving the sealing effect of the buffer bin; after the air flow enters the buffer bin from the air inlet, it can diffuse inside the buffer bin, reducing the gas pressure.

[0017] Preferably, a ventilation pipe is provided between the two buffer bins, and both ends of the ventilation pipe are respectively connected to the two buffer bins.

[0018] By adopting the above technical solution, a ventilation pipe is set between the two buffer bins. When one buffer bin is exhausted, a small amount of gas in the other buffer bin can enter this buffer bin through the ventilation pipe, so that the gas is quickly discharged; the ventilation pipe can also play a buffering role to prevent the gas in the diversion pipe from not circulating after the air pressure in the buffer bin is too high in the gas collection state, resulting in excessive pressure at the first spiral guide vane, thereby regulating the air pressure in the buffer bin in the gas collection state.

[0019] Preferably, the buffer assembly further includes: a gear ring, coaxially arranged on the diversion pipe; Two gears are coaxially fixed on one end of the two sealing plates; and a plurality of gears are all meshed with the gear ring.

[0020] By adopting the above technical solution, a gear ring is provided in the diversion pipe and a gear is provided at one end of the sealing plate, so that the energy when the airflow drives the rotating shaft to rotate is reasonably utilized, thereby avoiding energy waste.

[0021] Preferably, a spiral guide vane is provided in the Venturi tube.

[0022] By adopting the above technical solution, the second spiral guide vane can accurately guide the gas flow, so that the airflow in the Venturi tube can be stably integrated, and the pressure of the Venturi tube can be effectively adjusted to provide stable airflow for the control component.

[0023] Preferably, the control component includes: A driving member, arranged on the side wall of the air inlet duct; A valve is provided on the power output end of the driving member; the valve is located in the air inlet duct.

[0024] Preferably, the valve is a flexible diaphragm.

[0025] By adopting the above technical solution, the valve is set as a flexible diaphragm, so that when the airflow pressure at the regulating component changes, the air pressure squeezes the flexible diaphragm to cause deformation, effectively buffering and regulating the gas pressure.

[0026] In summary, this application includes at least one of the following beneficial technical effects: By arranging a Venturi tube in the air intake duct, the Venturi tube can optimize the flow state of the gas, so that the complex gas flowing into the air intake duct is gathered, and then dispersed through the curved side wall of the Venturi tube, so that the gas enters the regulating component evenly, and the gas is stably and continuously supplied to the compressor; the amount of gas entering the compressor is adjusted by the regulating component to maintain a reasonable amount of gas entering the compressor; the air pressure before entering the air intake duct and the air pressure after regulation are respectively detected by the first flow monitor and the second flow monitor, and the gas data before and after regulation are compared, and the regulating component is timely controlled by the central control module to regulate the amount of gas entering the compressor, so as to avoid excessive changes in the air pressure in the compressor and improve the service life of the equipment.

[0027] Two buffer bins are set in the diversion pipeline to reduce the air pressure generated after the gas enters the buffer bin; by setting a sealing plate in the buffer bin, when working, the two sealing plates are in the first state and the second state respectively, so that the two buffer bins work alternately, so that the gas entering the separation pipeline flows out in batches, and cooperates with the rotating shaft and the first spiral guide vane to achieve the effect of graded air pressure regulation, thereby improving the efficiency of air pressure regulation.

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses a compressor intake pressure stabilizing device. Figure 1 The compressor 1 intake pressure stabilizing device includes a compressor 1, an intake pipe 2, a regulating component 3, a venturi tube 4, a first flow monitor 5, a second flow monitor 6 and a central control module 9. The compressor 1 has an air inlet 11, and the outlet end of the intake pipe 2 is connected to the air inlet 11 of the compressor 1. The regulating component 3 is arranged on the intake pipe 2 and is located at the air inlet 11; the regulating component 3 has the freedom to move radially along the intake pipe 2, and the regulating component 3 is used to open and close the air inlet 11 to control the amount of gas entering the compressor 1; the venturi tube 4 is coaxially arranged in the intake pipe 2; the diameter of the air inlet 11 of the venturi tube 4 and the diameter of the air outlet are maintained within a specific ratio range, that is, the ratio of the diameter of the air inlet 11 of the venturi tube 4 to the diameter of the air outlet is 1 to 0.8 to 1 to 1.2. Within this ratio range, the venturi tube 4 can guide the gas to reasonably accelerate and decelerate in its cavity, reducing the generation of turbulence; the cavity length of the venturi tube 4 is set to 3 to 5 times the diameter of its air inlet 11, which ensures that the gas has sufficient space for pressure balance and flow adjustment, and avoids unnecessary energy loss and space occupation due to an excessively long cavity.

[0035] The diameter of the Venturi tube 4 is calculated by the formula Calculated; where d is the inner diameter of the Venturi tube 4; Q refers to the volume of fluid passing through a certain cross section of the Venturi tube 4 per unit time, in cubic meters per second; v is the flow velocity, which refers to the speed at which the fluid flows in the Venturi tube 4, in meters per second.

[0036] A first flow monitor 5 is located at the intake end of the intake duct 2; a second flow monitor 6 is located between the control assembly 3 and the air inlet 11. Both the first and second flow monitors 5 and 6 consist of a high-frequency pressure sensor and a flow meter. The high-frequency pressure sensor has an ultra-high sampling rate (≥1kHz), enabling it to quickly capture transient changes in gas pressure and accurately record subtle fluctuations in pressure data. The flow meter accurately measures gas flow, ensuring comprehensive monitoring of gas flow conditions. A central control module 9 is electrically connected to the first and second flow monitors 5 and 6, respectively, and the power source of the control assembly 3. The first and second flow monitors 5 and 6 accurately capture subtle changes in pressure and transient fluctuations in flow, quickly converting the physical signals into electrical or digital signals and transmitting them to the central control module 9. Based on the received information, the central control module 9 compares the gas data before and after regulation, applies a fast Fourier transform (FFT) algorithm to perform in-depth spectral analysis of the pressure fluctuations, accurately identifies their characteristics, and adjusts the gas flow entering the compressor 1 by controlling the operation of the control assembly 3.

[0037] The central control module 9 is connected to a communication module that supports multiple communication protocols and can establish a stable connection with remote monitoring equipment or local operation terminals. This control cabinet allows operators to operate and monitor the device locally, as well as remotely via remote communication. This allows operators to obtain real-time device operating status and parameters, flexibly adjust operating strategies, and achieve intelligent and convenient management.

[0038] Reference Figure 2-4, the air intake duct 2 is connected with a shunt duct 7; one end of each duct is connected to the air intake end of the air intake duct 2, and the other end is connected to the regulating component 3; a seal 71 is provided at each end of the air intake duct 2; the seal 71 includes a cylinder and a sealing door, and the cylinder is electrically connected to the central control module 9; to prevent the drawings from being disordered, the connection relationship between the cylinder and the central control module 9 is not shown in the figure; a buffer assembly 8 is provided in the shunt duct 7; the buffer assembly 8 includes a rotating shaft 81, a sealing plate 84, a gear ring 85, two gears 86, two buffer bins 83 and a plurality of guide plates 82; the rotating shaft 81 is coaxially arranged in the shunt duct 7; one end of the guide plate 82 is fixed on the side wall of the rotating shaft 81, and the other end is fixed to the inner wall of the shunt duct 7 Fitting; multiple guide plates 82 are evenly distributed along the circumference of the rotating shaft 81; an air inlet channel is formed between adjacent guide plates 82; two buffer bins 83 are symmetrically arranged on the rotating shaft 81; the buffer bin 83 is provided with an air inlet 831 and an air outlet 832; the buffer bin 83 is hemispherical; the outer wall of the buffer bin 83 fits with the side wall of the diversion pipe 7; the sealing plate 84 is rotatably arranged in the buffer bin 83; the sealing plate 84 is an arc-shaped plate; the sealing plate 84 can perfectly fit with the inner wall of the buffer bin 83; the sealing performance of the buffer bin 83 is increased; the sealing plate 84 covers the air inlet 831 and the air outlet 832; wherein, the sealing plate 84 has a first state of closing the air inlet 831 and a second state of closing the air outlet 832. The ring gear 85 is coaxially arranged on the diversion pipe 7; the gear 86 is fixed at one end of the sealing plate 84; the two gears 86 are engaged with the ring gear 85; after the rotating shaft 81 rotates, the sealing plate 84 can be driven to rotate through the gear 86 and the rack; a ventilation pipe 833 is provided between the two buffer bins 83, and the two ends of the ventilation pipe 833 are respectively connected to the two buffer bins 83.

[0039] Reference Figure 1The control component 3 includes a driver 31 and a valve 32; the driver 31 is arranged on the side wall of the air inlet duct; the valve 32 is arranged on the power output end of the driver 31; the valve 32 is a flexible diaphragm, located in the air inlet duct; the flexible diaphragm is made of a composite material of pressure-resistant rubber and Kevlar. Kevlar material has the characteristics of high strength and low density. After being compounded with the pressure-resistant rubber, the diaphragm can not only withstand high pressure, but also has excellent flexibility and fatigue resistance, so that the maximum deformation of the flexible diaphragm can reach ±20% of the cavity volume. This characteristic enables it to flexibly adjust its own shape when the gas pressure changes, thereby effectively buffering and regulating the gas pressure. The driver 31 is a linear motor or a piezoelectric ceramic actuator. The linear motor has the advantages of high precision, high speed and rapid response; the piezoelectric ceramic actuator has excellent micro-displacement control capabilities. Both can ensure that the stroke accuracy of the valve 32 displacement reaches ±0.1mm, realizing precise control of gas flow and pressure. The driving member 31 can also be replaced by a hydraulic piston group. The piston diameter Φ of the hydraulic piston group is between 80 and 150 mm, and the hydraulic pressure range is 0.5 to 3 MPa. The hydraulic piston group can provide a large driving force and is suitable for some working conditions that require high driving force, expanding the possibilities for the application scenarios of the execution unit. It has been verified in practice that the flexible diaphragm driven by the linear motor can control the intake pressure fluctuation range within a very small range, ensuring that the compressor 1 operates under a stable intake pressure, and greatly improving the compression efficiency of the compressor 1. The operating stability of the compressor 1 has been significantly enhanced, effectively reducing the abnormal vibration and noise caused by pressure fluctuations.

[0040] See also Figure 1 The venturi tube 4 is equipped with spiral guide vanes 41, forming a spiral channel that precisely guides the gas flow. The spiral angle is set between 15° and 45°, which effectively guides the gas into a stable spiral flow, promoting gas mixing and pressure balance. The guide vane spacing is controlled to be 0.2 to 0.5 times the diameter of the venturi tube 4's air inlet 11. In practice, a spiral angle of 20° and a spacing of 0.3 times the diameter of the venturi tube 4's air inlet 11 achieve the most ideal guiding effect, minimizing gas flow resistance and turbulence.

[0041] A damping plate is provided in the venturi tube 4, with a plurality of through holes formed on the damping plate; the aperture φ of the through holes is in the range of 2 to 5 mm, and the opening ratio of the damping plate is maintained at 60% to 80%; the gas is finely damped and diverted through the through holes, which can achieve the effect of stabilizing the airflow and reducing fluctuations. The damping plate structure is relatively simple and is therefore not shown in the accompanying drawings.

[0042] The central control module 9 is connected to a human-machine interface, which provides an intuitive and convenient operating platform for operators. The human-machine interface not only supports the pressure setting function, so that operators can easily set the target value of the intake pressure according to the operating requirements of the compressor 1; it also has a powerful fault diagnosis function. Through real-time analysis of system operation data, it can quickly and accurately locate the fault point and provide corresponding fault solutions. The central control module 9 is also connected to a storage module. The storage module has a historical data storage function and uses the Modbus communication protocol to interact with the human-machine interface for data. The Modbus communication protocol has the characteristics of strong versatility and good compatibility. It can perfectly match the communication protocol of the on-site compressor 1, realize fast and stable data transmission, and provide strong support for operators to conduct retrospective analysis of the operating status of the compressor 1 and optimize the equipment operating parameters.

[0043] The working principle of a compressor intake pressure stabilizing device in this application is: Before the gas enters the compressor 1, it is detected by the first flow monitor 5. The first flow monitor 5 transmits the detected pressure and flow data to the central control module 9, and the central control module 9 stores the data in the storage module; a first pressure range value is set in the central control module 9. When the pressure value detected by the first flow monitor 5 is equal to or less than the first pressure range value, the gas enters the intake pipe 2 normally, and then enters through the venturi tube 4. The venturi tube 4 can perform preliminary buffering on the intake air, change the gas flow rate, reduce the pressure fluctuation amplitude, and finally enter the regulating component 3. At this time, the regulating component 3 is opened. In the open state, the gas passes through the regulating component 3 and then the second flow monitor 6. The second flow monitor 6 transmits the detected value to the central control module 9. The central control module 9 is provided with a second pressure range value. When the pressure value detected by the second flow monitor 6 is greater than the second pressure range value, the central control module 9 controls the driving member 31 to drive the flexible diaphragm to move and reduce the air inlet 11 of the compressor 1; when the pressure value detected by the second flow monitor 6 is within the second pressure range value or less than the second pressure range value, the central control module 9 controls the driving member 31 to drive the flexible diaphragm to increase the air inlet 11 of the compressor 1.

[0044] When the pressure value detected by the first flow monitor 5 is within the first pressure range or less than the first pressure range, the central control module 9 controls the seal 71 to open, and a part of the gas enters the diversion pipe 7. The gas impacts the guide plate 82, causing the rotating shaft 81 to rotate. The gear 86, under the engagement of the rack, causes the sealing plate 84 to rotate continuously and continuously switch between the first state and the second state; the first state and the second state of the sealing plate 84 in the two buffer bins 83 are opposite; so that one of the two buffer bins 83 releases gas and the other collects gas; there is a buffer space 72 between the buffer bin 83 and the first spiral guide plate 82. After the airflow passes through the first spiral guide plate 82 and is dispersed into multiple airflows, it enters the buffer space 72. The buffer space 72 can buffer the airflow to prevent excessive air pressure in local areas; the airflow then enters one of the buffer bins 83, and a small amount of gas can enter the other buffer bin 83 through the ventilation pipe 833. When the other buffer bin 83 is exhausted, the gas can be discharged quickly and finally enter the control component 3.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
