Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
An oxygen generation plant 100 according to an embodiment of the invention is described below with reference to fig. 1-9, the oxygen generation plant 100 comprising: a pressure boosting device 10, a molecular sieve device 20, and a discharge control assembly 30.
Wherein the supercharging device 10 serves to increase the air pressure, the supercharging device 10 having an intake passage 11 and an exhaust passage 12. Air enters the supercharging device 10 through the intake passage 11 and is discharged from the exhaust passage 12 after being supercharged by the supercharging device 10, thereby increasing the air pressure in the exhaust passage 12 by the supercharging device 10. The molecular sieve device 20 is communicated with the exhaust channel 12, the molecular sieve device 20 is provided with an oxygen exhaust pipeline 21 and a nitrogen exhaust pipeline 22, air pressurized by the pressurization device 10 enters the molecular sieve device 20 from the exhaust channel 12, the molecular sieve device 20 can separate oxygen and nitrogen in the air, the separated oxygen is exhausted from the oxygen exhaust pipeline 21, and the nitrogen is exhausted from the nitrogen exhaust pipeline 22. Thus, oxygen can be delivered to a desired location by the oxygen generation plant 100 according to design requirements.
Further, the discharge control assembly 30 is disposed on the oxygen discharge pipe 21 to control the oxygen discharge amount of the oxygen discharge pipe 21, so as to ensure the oxygen discharge amount of the oxygen generator 100, ensure the oxygen concentration outputted by the oxygen generator 100 to be normal, and improve the working reliability of the oxygen generator 100.
It should be noted that, taking the oxygen exhaust duct 21 as an example, when there are impurities in the oxygen exhaust duct 21, the oxygen exhaust duct 21 has a problem of blockage, which affects the discharge of oxygen from the oxygen exhaust duct 21, and at the same time, will cause a sharp increase in the pressure in the oxygen exhaust duct 21, so that there is a risk of bursting of the oxygen exhaust duct 21. Wherein, the discharge control module 30 controls the oxygen discharge amount of the oxygen discharge pipe 21 to prevent the pressure in the oxygen discharge pipe 21 from increasing sharply, and simultaneously, the oxygen discharge amount of the oxygen discharge pipe 21 is ensured, so as to improve the working safety and reliability of the oxygen generator 100.
According to the oxygen generating apparatus 100 of the embodiment of the invention, the oxygen generating apparatus 100 can separate oxygen and nitrogen in the air, and discharge the oxygen from the oxygen discharge pipe 21, and the discharge control assembly 30 can control the oxygen discharge amount of the oxygen discharge pipe 21, so as to ensure that the oxygen concentration output by the oxygen generating apparatus 100 is normal, and at the same time, the problem of sudden change of pressure in the pipe due to blockage of the oxygen discharge pipe 21 can be effectively prevented, and the stability and reliability of the operation of the oxygen generating apparatus 100 can be improved.
In some embodiments of the present invention, the oxygen generating apparatus 100 further comprises a pressure detecting device 40, the pressure detecting device 40 is used for detecting the pressure in the oxygen discharging passage, and the pressure detecting device 40 is connected with the discharging control assembly 30. The discharge control module 30 is configured to control the oxygen discharge amount of the oxygen discharge pipe 21 based on the detection result of the pressure detection means 40.
Specifically, the pressure detection device 40 may detect the pressure in the oxygen discharge pipe 21, so as to detect the pressure in the oxygen discharge pipe 21 through the pressure detection device 40 to determine the operating condition of the oxygen discharge pipe 21, and the discharge control module 30 may control the oxygen discharge pipe 21 according to the detection result of the pressure detection device 40, so as to prevent the pressure in the oxygen discharge pipe 21 from being too large, and simultaneously ensure the oxygen discharge amount of the oxygen discharge pipe 21.
For example: when the pressure detecting device 40 detects that the pressure value in the oxygen discharging pipe 21 is rapidly increased, there may be a problem of blockage in the oxygen discharging pipe 21, and the discharge control module 30 may control the oxygen discharging manner of the oxygen discharging pipe 21 to control the oxygen discharging amount of the oxygen discharging pipe 21, so as to prevent the pressure in the oxygen discharging pipe 21 from being continuously increased, and simultaneously ensure the output of oxygen.
In a particular embodiment of the invention, the discharge control assembly 30 is a flow valve 31 connected in series on the oxygen discharge line 21. The flow valve 31 can control the oxygen flow rate in the oxygen discharge pipe 21, thereby adjusting the oxygen discharge amount.
Specifically, the flow rate of oxygen passing through the flow valve 31 can be controlled by adjusting the opening degree of the flow valve 31, and when the opening degree of the flow valve 31 is increased, the oxygen discharge amount will be increased; when the opening degree of the flow valve 31 is decreased, the oxygen discharge amount will be decreased.
In combination with the characteristics of the pressure detection device 40, when the pressure detection device 40 detects that the pressure in the oxygen discharge pipeline 21 increases, it indicates that there is a risk of blockage in the oxygen discharge pipeline 21, so that the opening degree of the flow valve 31 needs to be increased to ensure the oxygen discharge amount of the oxygen discharge pipeline 21; when the pressure detection means 40 detects that the pressure in the oxygen discharge conduit 21 is unchanged or that the fluctuation of the change is small, the flow valve 31 may be kept at the current opening degree, i.e. without adjusting the opening degree of the flow valve 31.
In other embodiments of the present invention, the oxygen discharge line 21 includes a common line 211, a main line 212, and a standby line 213, the common line 211 is connected to the molecular sieve device 20, the discharge control assembly 30 includes a switching valve 32, the switching valve 32 is respectively connected to the common line 211, the main line 212, and the standby line 213, and the switching valve 32 controls the common line 211 to be in switching communication with the main line 212 and the standby line 213.
Specifically, when oxygen is discharged from the molecular sieve device 20, the oxygen flows into the common pipe 211, and the switching valve 32 is used to switch the communication state of the common pipe with the main pipe 212 and the standby pipe 213 to control the flow of the oxygen into the main pipe 212 or the standby pipe 213 from the common pipe 211. It will be appreciated that when common conduit 211 is in communication with main conduit 212, oxygen in common conduit 211 flows into main conduit 212 and is discharged from main conduit 212; when the common line 211 communicates with the reserve line 213, oxygen in the common line 211 flows into the reserve line 213 and is discharged from the reserve line 213.
It is noted that the communication state of the common pipe 211 with the main pipe 212 and the standby pipe 213 can be adjusted according to the discharge demand of the oxygen plant 100. When the pressure in the oxygen discharge line 21 is normal, the common line 211 communicates with the main line 212, and oxygen can be discharged from the main line 212.
Further, referring to fig. 9, a pressure detecting device 40 is provided to the common pipe 211, the pressure detecting device 40 may detect the pressure of the common pipe 211, a direction valve is disposed downstream of the common pipe 211 where the pressure sensor is provided, and the direction valve is located at the intersection of the main pipe 212, the standby pipe 213, and the common pipe 211. When the pressure detection device 40 detects a pressure abnormality of the oxygen discharge conduit 21, the common conduit 211 may communicate with the backup conduit 213, and oxygen may be discharged from the backup conduit 213. If the pressure detection device 40 detects that the pressure of the oxygen discharge pipeline 21 is recovered to normal, it indicates that a fault exists in the main pipeline 212; if the pressure detection device 40 detects that the pressure in the oxygen discharge line 21 is still abnormal, it indicates that the common line 211 has a failure. Wherein the failure may include problems such as pipe plugging.
In some embodiments of the present invention, a throttle valve is provided between the main conduit 212 and the diverter valve, which may control the flow of oxygen in the main conduit 212.
In some embodiments of the present invention, the oxygen generator 100 further comprises a display device 50, the display device 50 is connected to the discharge control assembly 30 and the pressure detection device 40, and the discharge control assembly 30 controls the display device 50 to display information according to the detection result of the pressure detection device 40, so as to remind the user of the working state of the oxygen generator 100.
Further, when the detection result of the pressure detection device 40 is abnormal, the discharge control assembly 30 may adjust the connection state of the oxygen discharge channel, and the display device 50 may display prompt information that the oxygen discharge channel has a fault, needs to be maintained, and the like; when the detection result of the pressure detection device 40 is normal, the discharge control module 30 does not need to adjust the oxygen discharge passage, and the display device 50 may display information such as the oxygen discharge amount and time.
Alternatively, when the oxygen discharge duct 21 of the oxygen generating apparatus 100 is differently configured, the display contents of the display apparatus 50 will be different. Such as: the oxygen discharge pipe 21 includes a common pipe 211, a main pipe 212, and a spare pipe 213, and whether there is a failure in the common pipe 211, the main pipe 212, or the spare pipe 213 can be determined by a detection result of the pressure detection device 40, and when any one of the pipes fails, the display device 50 can display the pipe to be maintained, thereby prompting an operator of the pipe to be maintained, and the operator can maintain the pipe in a targeted manner.
In some embodiments of the present invention, the oxygen generating apparatus 100 further includes a filter 60, the filter 60 is communicated with the air intake channel 11, and a filter core is disposed in the filter 60, and the filter core may be a filter element such as a filter screen. Thus, the air entering the supercharging device 10 may be filtered by the filter 60 to prevent dust particles from entering the supercharging device 10 and causing damage to the supercharging device 10.

Specifically, the heat dissipation device 70 is configured as a heat dissipation fan, and the heat dissipation opening 204 is used for exhausting air from the heat dissipation fan to exhaust heat in the installation cavity out of the enclosure 200.
According to the control method of the oxygen generating device 100 of the embodiment of the invention, the oxygen generating device 100 comprises the oxygen exhaust pipeline 21 and the exhaust control assembly 30, the exhaust control assembly 30 is used for adjusting the oxygen exhaust amount of the oxygen exhaust pipeline 21, and the control method comprises the following steps: after the oxygen generating device 100 is started, acquiring a pipeline pressure value Pt in the oxygen exhaust pipeline 21; calculating the difference value between the pipeline pressure value Pt and preset pressure data to obtain a pressure difference value Ps; comparing the pressure difference value Ps with a preset pressure value; when the pressure difference value Ps is greater than the preset pressure value, the discharge control module 30 is controlled to increase the oxygen discharge amount of the oxygen discharge pipe 21.
Specifically, after the oxygen generator 100 is started, oxygen is discharged from the oxygen discharge pipe 21, the pressure of the oxygen discharge pipe 21 can be detected by the pressure detection device 40, the difference between the pipe pressure value and the preset pressure value is calculated, and the pressure difference is compared with the preset pressure value, so as to determine whether the oxygen discharge pipe 21 has a fault. When the pressure difference Ps is greater than the preset pressure value, which indicates that there may be a blockage problem in the oxygen discharge pipe 21, it is necessary to control the discharge control module 30 to increase the oxygen discharge amount of the oxygen discharge pipe 21 so as to ensure the oxygen output capacity of the oxygen generator 100.
In a further embodiment of the present invention, the obtaining of the line pressure value Pt in the oxygen discharge line 21 after the oxygen generating apparatus 100 is started comprises: and detecting the exhaust pressure in the oxygen exhaust pipeline 21 in real time, and calculating the average pressure value in the time period at intervals of first preset time to obtain a pipeline pressure value Pt.
It can be understood that the detection of the duct pressure value is more accurate by detecting the magnitude of the exhaust pressure over a period of time and by calculating the average pressure value to obtain the duct pressure value with higher reliability.

When the oxygen discharge passage is blocked, the pressure in the pipeline may be increased sharply, and thus problems such as pipeline burst or interface burst may occur, and at this time, the opening degree of the flow valve 31 needs to be increased to ensure the oxygen discharge amount and prevent the pressure in the pipeline from increasing sharply.

Specifically, when oxygen is discharged from the molecular sieve device 20, the oxygen flows into the common pipe 211, and the switching valve 32 is used to switch the communication state of the common pipe with the main pipe 212 and the standby pipe 213 to control the flow of the oxygen into the main pipe 212 or the standby pipe 213 from the common pipe 211. When the common conduit 211 is in communication with the main conduit 212, oxygen in the common conduit 211 flows into the main conduit 212; when the common line 211 communicates with the reserve line 213, oxygen in the common line 211 flows into the reserve line 213.
Further, after the oxygen generating device 100 is started, the common pipe 211 is in a state of being communicated with the main pipe 212, and oxygen enters the main pipe 212 from the common pipe 211, when the pressure difference Ps is greater than the preset pressure value, it indicates that there is a risk of blockage in the main pipe 212, and if the output of oxygen from the main pipe 212 is still maintained, the pipe may burst. The common line 211 is communicated with the reserve line 213 by the switching valve 32, and oxygen is introduced into the reserve line 213 from the common line 211.
Further, when the pressure difference between the common pipe 211 and the standby pipe 213 is still greater than the preset pressure value, which indicates that there is a risk of blockage in the common pipe 211, the oxygen production apparatus 100 can be shut down.
Wherein the oxygen discharge duct 21 may be provided with a plurality of spare ducts 213 to improve the reliability of the oxygen generating apparatus 100.
