DETAILED DESCRIPTION
[0027] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0028] Referring to Figure 1 , the specific structure diagram of the piston oxygen compressor 6 in the prior art, from the figure, it can be seen that the piston oxygen compressor 6 is not configured with corresponding damping device on the air inlet pipeline 601 and the air outlet pipeline 602, the low-pressure oxygen enters the piston oxygen compressor 6 from the air inlet pipeline 601, and after the compression treatment of the piston oxygen compressor 6, it is introduced into the user through the air outlet pipeline 602. Because the piston oxygen compressor 6 will produce huge pressure fluctuation when it works, which will cause corresponding vibration impact on the air inlet pipeline 601 and the air outlet pipeline 602, and bring certain risk to the pipeline operation.
[0029] In order to solve the above problems, the present application provides a piston oxygen compressor damping system, as shown in Figure 2 , specifically comprising a first buffer tank 1, a second buffer tank 2, a pneumatic regulating valve 3, a first manual stop valve 4 and a second manual stop valve 5.
[0030] Specifically, the first buffer tank 1 is arranged on the inlet pipeline 601, and the second buffer tank 2 is arranged on the outlet pipeline 602. The first buffer tank 1 is used to buffer the oxygen entering the piston oxygen compressor 6 and provide corresponding gas pressure buffering for the inlet pipeline 601; and the second buffer tank 2 is used to buffer the oxygen compressed by the piston oxygen compressor 6 and provide corresponding pipeline pressure buffering for the outlet pipeline 602. Because the first buffer tank 1 and the second buffer tank 2 can buffer a certain amount of oxygen, the entire system can quickly adapt to demand changes when responding to oxygen supply demand. Accordingly, the frequent start-stop phenomenon of system operation can be reduced, the service life of each equipment unit can be prolonged, and the maintenance cost can be reduced.
[0031] The first buffer tank 1 and the second buffer tank 2 are both made of stainless steel, which prevents the tank body from rusting due to long-term use. The capacity of the first buffer tank 1 and the second buffer tank 2 can be adaptively adjusted according to actual production needs, as long as the oxygen safety is ensured.
[0032] In the embodiment, a pneumatic regulating valve 3 is arranged upstream of the first buffer tank 1. The pneumatic regulating valve 3 is used to regulate the inlet flow of untreated low-pressure oxygen. The operator can adjust the flow size of the oxygen according to actual production needs. More specifically, the pneumatic regulating valve 3 cooperates with the first buffer tank 1 and the second buffer tank 2, so that the gas flow size on the inlet pipeline 601 and the outlet pipeline 602 tends to be flat, and the pressure fluctuation influence of the self-vibration of the piston oxygen compressor 6 on the pipeline and the system is reduced.
[0033] In the embodiment, a first manual stop valve 4 is further arranged between the first buffer tank 1 and the pneumatic regulating valve 3. When daily maintenance and repair of the piston oxygen compressor 6 or the pipeline are needed, the first manual stop valve 4 can quickly cut off the inlet source.
[0034] In the embodiment, a second manual stop valve 5 is synchronously arranged downstream of the second buffer tank 2. The second manual stop valve 5 is arranged between the outlet pipeline 602 and the user. When the outlet pipeline 602 or the piston oxygen compressor 6 fails, the second manual stop valve 5 can quickly cut off the gas source.
[0035] The first buffer tank 1 is provided with a first gas inlet 101 and a first gas outlet 102, and the first gas inlet 101 is higher than the first gas outlet 102. Similarly, the second buffer tank 2 is provided with a second gas inlet 201 and a second gas outlet 202, and the second gas inlet 201 is higher than the second gas outlet 202. In this embodiment, the first gas outlet 102 of the first buffer tank 1 and the second gas inlet 201 of the second buffer tank 2 are located on the same horizontal line, which can reduce the backflow of gas in the pipeline due to gravity or other factors, thereby maintaining the directionality of the gas flow. And it can also well realize the balance of gas pressure, avoid the unevenness of pressure caused by height difference, and improve the system efficiency.
[0036] In this embodiment, the top of the first buffer tank 1 is provided with a first safety valve 103 for opening when the gas pressure value in the first buffer tank 1 exceeds the set value, so as to discharge the excess oxygen in the first buffer tank 1. The first buffer tank 1 is also provided with a first local pressure gauge 104 for monitoring the oxygen pressure in the first buffer tank 1. Similarly, the top of the second buffer tank 2 is provided with a second safety valve 203 for discharging excess oxygen in the second buffer tank 2 and maintaining the balance of gas pressure in the second buffer tank 2. The second buffer tank 2 is provided with a second local pressure gauge 204 for monitoring the oxygen pressure in the second buffer tank 2. The safety valve and the local pressure gauge on the buffer tank can ensure the safety of the system in real time.
[0037] In addition, in order to avoid the first buffer tank 1 and the second buffer tank 2 from being contaminated, a first blowdown port 105 is opened at the bottom of the first buffer tank 1, and the first blowdown port 105 is connected to the outside through a first blowdown pipeline, and a first blowdown valve 106 is arranged on the first blowdown pipeline for controlling blowdown. The second buffer tank 2 is provided with a second blowdown port 205 at the bottom, and the second blowdown port 205 is connected to the outside through a second blowdown pipeline, and a second blowdown valve 206 is arranged on the second blowdown pipeline for controlling blowdown. The blowdown port, the blowdown pipeline and the blowdown valve can flush the dirt and harmful impurities in the buffer tank and discharge them in time, avoiding contamination of the oxygen in the tank.
[0038] In summary, the piston oxygen compressor damping system disclosed in the utility model, through setting first buffer tank 1 and second buffer tank 2 on the inlet pipeline 601 and outlet pipeline 602 of piston oxygen compressor 6 respectively, buffer oxygen by buffer tank, simultaneously buffer the gas pressure in the inlet pipeline 601 and outlet pipeline 602, avoid the gas pressure in pipeline being too large, make the gas flow tend to be gentle, can be adjusted adaptively when facing system oxygen supply demand.In addition, the utility model discloses a pneumatic regulating valve 3 is set on the inlet pipeline 601 of piston oxygen compressor 6, and the oxygen inlet flow is adjusted in real time.
[0039] In addition, by setting first manual stop valve 4 between first buffer tank 1 and pneumatic regulating valve 3 for cutting off the oxygen on-off of inlet pipeline 601, by setting second manual stop valve 5 downstream of second buffer tank 2 for cutting off the oxygen on-off of outlet pipeline 602, so as to maintain the system maintenance. Buffer tank reduces the complexity caused by pressure and flow fluctuation, reduces the difficulty of daily maintenance and operation of the system, makes the system monitoring and management more convenient.
[0040] The above embodiment is only for illustrating the technical concept and characteristics of the utility model, and its purpose is to enable the person skilled in the art to understand the content of the utility model and to implement it, and it cannot limit the protection scope of the utility model, and any equivalent changes or modifications according to the spirit and essence of the utility model should be covered within the protection scope of the utility model.
