DETAILED DESCRIPTION
[0027] like Figure 1 As shown, the high-pressure air purification system includes an air conveyor 15 , a particle filter 1 , a molecular sieve filter air path and an air tank 16 .
[0028] The air conveyor 15 is quickly connected to the particle filter 1 through the quick connection 12. The type of gas conveyed is provided by the air conveyor 15, and the air conveyor 15 provides air circuit pressure for the high-pressure air purification system.
[0029] The gas is conveyed from the air conveyor 15 to the particle filter 1 , which filters impurities and pollutants in the air, purifying the air while also preventing the impurities from damaging other equipment.
[0030] The outlet pipeline of the particle filter 1 is connected to the air inlets of the two molecular sieve filter air paths through the electromagnetic reversing valve (three-way two-position electromagnetic valve 2). A conversion joint 6 is provided between the particle filter 1 and the three-way two-position electromagnetic valve 2.
[0031] The two molecular sieve filtration gas paths are gas path I and gas path II with exactly the same configurations. A molecular sieve filter 7 with a heating device 8 is installed on the molecular sieve filtration gas path.
[0032] When the molecular sieve in the molecular sieve filter 7 in gas path I needs to be regenerated, the air coming out of the particle filter 1 enters the three-way, two-position solenoid valve 2. The three-way, two-position solenoid valve 2 is in a state where gas path II is connected and gas path I is disconnected. Air enters gas path II. At this time, the heating device 8 in gas path I is started. When heated to a certain temperature, the moisture and carbon dioxide adsorbed in the molecular sieve filter 7 are converted into waste gas and remain in the pipeline, so that the molecular sieve can be regenerated. At the same time, the solenoid valve is used to adjust the pipeline connecting gas path I to the muffler 4 to be fully opened, and the residual waste gas is discharged from the muffler 4 to the outside. When the molecular sieve in gas path II needs to be regenerated, the above process is also carried out. This not only eliminates the production time occupied by the process of replacing the filter element of the filter, but also ensures production efficiency.
[0033] The outlet of the molecular sieve filter gas path is connected to the gas tank 16 and the muffler 4 respectively through an electromagnetic reversing valve.
[0034] Five molecular sieve filters 7 are installed in sequence on gas path I and gas path II, and a conversion joint 6 is provided between the molecular sieve filters 7. A muffler 4 is installed before the first molecular sieve filter 7. The muffler 4 is connected to the molecular sieve filter gas path through a tee 5. A two-way, two-position solenoid valve 3 is also installed between the tee 5 and the muffler 4 for on and off; an elbow 9 is also installed on the pipeline between the first molecular sieve filter 7 and the second molecular sieve filter 7.
[0035] The outlets of the electromagnetic reversing valves at the outlets of the two-way molecular sieve filtration gas paths, which are connected to the gas tanks 16, are respectively connected to the two inlets of the four-way valve 10. One outlet of the four-way valve 10 is divided into six paths and connected to the six gas tanks 16 through six needle valves 11 respectively. The other outlet of the four-way valve is connected to another gas tank 16 after passing through the pressure regulating valve 13.
[0036] A quick connection 12 is provided between the gas tank 16 and the needle valve 11 .
[0037] A pressure transmitter 14 is provided between the pressure regulating valve 13 and the gas tank 16 .
[0038] A two-way, two-position solenoid valve 3 is provided between the pressure regulating valve 13 and the gas tank 16 .
[0039] The molecular sieve filter 7 is a 13X molecular sieve.
[0040] In a specific embodiment: when delivering high-purity air to the air storage tank, the quick connector 12 allows the high-pressure air system to quickly connect the air conveyor 15 and the air tank 16; the particulate filter 1 filters impurities and pollutants entering the high-pressure air purification system, and also protects the equipment; the conversion joint 6 connects the pipeline in the high-pressure air system; the three-way two-position solenoid valve 2 reverses the air flow channel in the high-pressure air system; the two-way two-position solenoid valve 3 controls the start and stop of part of the flow channel of the high-pressure air system; the muffler 4 reduces the noise in the high-pressure air system and discharges the exhaust gas generated; the three-way 5 connects the pipeline interface in the high-pressure purified air system to increase the air channel; the molecular sieve filter 7 adsorbs and separates water, carbon dioxide and hydrogen sulfide in the air to achieve the purpose of high-pressure air purification; the heating device 8 heats the molecular sieve to regenerate the molecular sieve; the elbow 9 changes the direction of the air channel and the four-way 10 increases the air channel; the needle valve 11 cuts off or adjusts the exhaust flow; the pressure regulating valve 12 adjusts and controls the air pressure; and the pressure transmitter 13 measures and collects the pressure data in the pipeline.
[0041] This high-pressure air purification system can deliver both high-pressure and low-pressure air to gas tanks; it has multiple gas flow paths to improve air purification efficiency; the molecular sieve can be regenerated by heating, eliminating the process of replacing the filter element, which takes up production time. In addition, it also reduces the cost of replacing the filter element in the high-pressure air purification system; in addition to the particulate filter, there are 5 molecular sieve filters on each airway to ensure the quality of air purification; there are multiple silencers on each airway, which not only reduces the noise during the air purification process, but also can discharge the exhaust gas generated by heating the molecular sieve and the air purification process.
