Description

Technical Field

[0001] The utility model relates to an air purification system for an oxygen-nitrogen separation tower, in particular to a double-circulation air purifier for an oxygen-nitrogen separation tower. Background Art

[0002] Oxygen and nitrogen, as the most widely used industrial gases, are an indispensable and important part of the modern industrial system. The existing oxygen and nitrogen production systems are mainly composed of separators, air compressors, air purifiers, air dryers, nitrogen and oxygen separation towers, purification tanks, oxygen boosting systems and nitrogen boosting systems. After the air is processed by the above equipment in sequence, oxygen and nitrogen are obtained respectively. However, the existing air purifier mainly includes a shell and oil removal modules and dust removal filters arranged in sequence in the shell along the air flow direction, which are not very ideal for air purification; moreover, it is generally a single-channel structure. Regardless of the size of the gas processing flow, it can only be processed through the various modules in the channel, which is easy to cause waste of resources, and when the air purifier needs maintenance, it will cause the entire device to be unusable.

[0003] Therefore, the existing technology has the problems of unsatisfactory purification effect and easy waste of resources. Utility Model Content

[0004] The purpose of the utility model is to provide a double-circulation air purifier for an oxygen-nitrogen separation tower. The utility model has the characteristics of being able to effectively improve the purification effect and reduce resource waste.

[0005] The technical solution of the utility model is: a double-circulation air purifier for an oxygen-nitrogen separation tower, comprising a shell, an air inlet is provided at one end of the shell, an air outlet is provided at the other end of the shell, two air flow channels distributed side by side are provided between the air inlet and the air outlet, and an oil removal module, a dust removal module and an activated carbon filter module are sequentially provided in each air flow channel along the gas flow direction; a rotating baffle located between the two air flow channels is also provided in the middle of the air inlet;

[0006] The dust removal module comprises a plasma dust removal unit, an electrostatic dust removal unit and a nano water ion sterilization module which are arranged in sequence.

[0007] In the aforementioned double-circulation air purifier for an oxygen-nitrogen separation tower, an exhaust fan is provided at the air outlet.

[0008] In the aforementioned double-circulation air purifier for an oxygen-nitrogen separation tower, a fan is provided at the inlet of each air flow channel.

[0009] In the aforementioned dual-circulation air purifier for an oxygen-nitrogen separation tower, a rotating shaft is provided between the rotating baffle and the shell, and a driving module matched with the rotating shaft is provided on the outside of the shell.

[0010] In the aforementioned dual-circulation air purifier for an oxygen-nitrogen separation tower, the edges on both sides of the rotating baffle are provided with suction magnets; a stepped groove matching the rotating baffle is provided at the entrance of the air flow channel, and an electromagnet is embedded in the stepped groove.

[0011] Compared with the prior art, the utility model sets two air flow channels distributed side by side between the air inlet and the air outlet of the shell, and sets an oil removal module, a dust removal module and an activated carbon filter module in each air flow channel, so that one or two air flow channels can be selected for processing according to the actual processing situation, saving resources and extending the service life of each processing module. Moreover, when the processing module in one of the air flow channels needs to be repaired, another air flow channel can be enabled for standby, which does not affect the normal use of the entire oxygen and nitrogen production device. At the same time, the utility model can effectively improve the purification effect through the mutual cooperation between the oil removal module, the dust removal module (the plasma dust removal unit, the electrostatic dust removal unit and the nano water ion sterilization module arranged in sequence) and the activated carbon filter module. In summary, the utility model has the characteristics of being able to effectively improve the purification effect and reduce the waste of resources.

[0012] The present application provides a rotating baffle in the middle of the air inlet, so that one of the air flow channels can be opened or closed according to actual conditions, with a simple structure and flexible adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0016] Embodiment. A double-circulation air purifier for an oxygen-nitrogen separation tower, comprising: Figure 1 As shown, it comprises a shell 1, an air inlet 2 is provided at one end of the shell 1, an air outlet 3 is provided at the other end of the shell 1, two air flow channels 4 distributed side by side are provided between the air inlet 2 and the air outlet 3, and an oil removal module 5, a dust removal module 6 and an activated carbon filter module 7 are sequentially provided in each air flow channel 4 along the gas flow direction; a rotating baffle 8 located between the two air flow channels 4 is also provided in the middle of the air inlet 2;

[0017] The dust removal module 6 includes a plasma dust removal unit 601, an electrostatic dust removal unit 602 and a nano water ion sterilization module 603 which are arranged in sequence.

[0018] The air outlet 3 is provided with an exhaust fan 9 .

[0019] A fan 10 is provided at the inlet of each air flow channel 4 .

[0020] A rotating shaft 11 is disposed between the rotating baffle 8 and the housing 1 , and a driving module matched with the rotating shaft 11 is disposed outside the housing 1 .

[0021] The edges of both sides of the rotary baffle 8 are provided with magnets 13 ; the entrance of the airflow channel 4 is provided with a stepped groove 14 matched with the rotary baffle 8 , and the stepped groove 14 is embedded with an electromagnet 12 .

[0022] The drive module includes a self-locking drive motor, a drive gear is provided on the output shaft of the self-locking drive motor, and a matched driven gear is provided on the rotating shaft. The forward and reverse rotation of the self-locking drive motor drives the rotating shaft and the rotating baffle to rotate forward or reverse through the cooperation of the drive gear and the driven gear.

[0023] The oil removal module and the activated carbon filter module can both adopt structures commonly used in the market.

[0024] The circulation purification process of the utility model: when the air purification flow rate is small, only one air flow channel needs to be opened for air purification operation; at this time, the rotating baffle is rotated 90 degrees to the left or right under the action of the driving module to make it in a horizontal state, and the rotating baffle will block the entrance of one of the air flow channels (making the air flow channel closed), and the fan at the entrance of the other air flow channel is turned on to suck air into the air flow channel. The air is successively subjected to the oil removal treatment of the oil removal module, the dust removal and sterilization treatment of the dust removal module, the odor removal and adsorption treatment of the activated carbon filter module, and finally discharged from the air outlet under the action of the exhaust fan to complete the air purification treatment.

[0025] When two air flow channels need to be processed simultaneously, the rotary baffle is in the initial state (vertical state), and the air enters the air flow channel under the action of the fan to be purified in turn.

[0026] After the rotating baffle rotates 90 degrees, the magnets on both sides of the rotating baffle will be attracted to the electromagnet embedded in the stepped groove at the entrance of the airflow channel (the magnetic poles of the electromagnet are opposite to the magnets, and the two are attracted to each other); when adsorption is not needed, the electromagnet is powered off, and the magnets and the electromagnet are not attracted to each other. At this time, the driving module drives it to rotate 90 degrees in the opposite direction, that is, return to the initial position. The above structure can ensure that the rotating baffle can be firmly adsorbed at the entrance of the airflow channel, with a simple structure and easy operation.

[0027] The dust removal module includes a plasma dust removal unit, an electrostatic dust removal unit and a nano water ion sterilization module. The air passes through each of the above units in turn, which can effectively complete the dust removal and sterilization treatment.
