Description

Technical Field

[0001] This utility model relates to the field of PSA nitrogen generator technology, specifically a novel air intake and collection structure. Background Technology

[0002] PSA (Pressure Swing Adsorption) nitrogen generators are widely used on land and ships to produce nitrogen. This equipment uses air as raw material and carbon molecular sieves as adsorbents. It utilizes the principle of pressure swing adsorption, taking advantage of the selective adsorption of oxygen and nitrogen by the carbon molecular sieves to separate them.

[0003] The shortcomings of existing technology:

[0004] The current traditional bottom air intake structure directly introduces compressed air, which impacts the molecular sieve directly and in a concentrated manner, resulting in uneven air intake. Prolonged impact can also reduce the service life of the molecular sieve, causing it to easily pulverize and loosen the filling inside the tank, thus affecting the normal operation and service life of the entire equipment. Furthermore, the traditional top air collection structure uses a single pipe for collection, resulting in a small contact cross-sectional area and low efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a novel air intake and air collection structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel air intake and collection structure, comprising a nitrogen generator body, wherein the nitrogen generator body is provided with a bottom air intake and a top air collection point, wherein a buffer component for buffering the air intake force is installed inside the bottom air intake, and a buried multi-tube collection component for collecting nitrogen is installed at the top air collection point, wherein the buried multi-tube collection component is installed on the inner side wall of the nitrogen generator body.

[0007] Preferably, the buffer component includes:

[0008] A central perforated plate, which is used to buffer the impact force of the intake air;

[0009] Several fan blades are fixedly mounted on the side wall of the bottom air inlet. The fan blades are evenly spaced on the side of the central perforated plate. The fan blades are used to buffer the impact force of the incoming air. The central perforated plate is fixed to the side wall of the bottom air inlet through the fan blades.

[0010] Preferably, the embedded multi-tube collection assembly includes:

[0011] A gas collecting pipe is provided on the side wall of the nitrogen generator body via a connector, and the connector is installed on the side wall of the nitrogen generator body.

[0012] A gas collecting head is provided, and several welded threaded branch pipe seats are fixedly installed on both sides of the gas collecting pipe. The gas collecting head is connected to the welded threaded branch pipe seats and installed on the gas collecting pipe.

[0013] End caps are installed at both ends of the gas collecting pipe to reduce gas leakage.

[0014] Preferably, the gas collecting head has several small holes around its perimeter for collecting gas.

[0015] Preferably, the gas collecting pipe is connected to an outlet assembly, which includes a first connecting pipe, a second connecting pipe, and a third connecting pipe. The first connecting pipe, the second connecting pipe, and the third connecting pipe are interconnected and disposed in the gas collecting pipe. The first connecting pipe and the second connecting pipe are connected by a short-radius elbow pipe, and the second connecting pipe and the third connecting pipe are connected by a threaded swivel joint.

[0016] Preferably, the second connecting pipe and the third connecting pipe are connected to the threaded joint via a threaded connection.

[0017] Preferably, a baffle is installed on the nitrogen generator body near the bottom air inlet. The two ends of the baffle are fixed to the side wall of the nitrogen generator body by fixing members. The fixing members are installed on the side wall of the nitrogen generator body. The baffle is used to buffer the impact force of the intake air.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This novel air intake and collection structure incorporates a buffer assembly, which includes a central perforated plate and several fan blades. The fan blades are fixedly mounted on the side wall of the bottom air intake, and are evenly spaced on the side of the central perforated plate. The central perforated plate is fixed to the side wall of the bottom air intake via the fan blades. The fan blades buffer the impact force of the incoming air. After passing through the fan blades, the compressed air changes from direct intake to spiral intake, which not only resists the impact of compressed air but also disperses the incoming air, ensuring more thorough contact between the incoming air and the molecular sieve. This improves adsorption efficiency, shortens the nitrogen production cycle, increases nitrogen production, and extends the service life of the molecular sieve and the overall equipment.

[0020] 2. This novel air intake and collection structure is equipped with an embedded multi-pipe collection component, which includes a collection pipe, a collection head, and a cap. The multiple collection heads can increase the contact area and the gas collection coverage area, improve collection efficiency, reduce waste, and shorten the nitrogen collection cycle.

The fan blades 22 are all fixedly installed on the side wall of the bottom air intake 11. The fan blades 22 are evenly spaced on the side of the central perforated plate 21. The central perforated plate 21 is fixed to the side wall of the bottom air intake 11 by the fan blades 22. The fan blades 22 are used to buffer the impact force of the air intake. The buried multi-tube collection assembly... Component 3 includes a gas collecting pipe 31, a gas collecting head 33, and a sealing head 35. The gas collecting pipe 31 is installed on the side wall of the nitrogen generator body 1 via a connector 32. The connector 32 is installed on the side wall of the nitrogen generator body 1. Several welded threaded branch pipe seats 34 are fixedly installed on both sides of the gas collecting pipe 31. The gas collecting head 33 is threadedly connected to the welded threaded branch pipe seat 34 and installed on the gas collecting pipe 31, which facilitates the later installation, maintenance, and replacement of the gas collecting pipe 31. The multiple gas collecting heads 33 can increase the contact area and the gas collection coverage area, improve the collection efficiency, reduce waste, and shorten the nitrogen collection cycle. Several small holes for gas collection are opened around the gas collecting head 33. Nitrogen enters the gas collecting pipe 31 through the small holes. Sealing heads 35 are installed at both ends of the gas collecting pipe 31 to reduce gas leakage.

[0032] The gas collecting pipe 31 is connected to an outlet assembly, which includes a first connecting pipe 311, a second connecting pipe 312, and a third connecting pipe 313.

[0034] In use, compressed air enters from the air inlet 11 at the bottom of the nitrogen generator body 1. After passing through the fan blades 22, the compressed air changes from direct air intake to spiral air intake, which can resist the impact of compressed air and disperse the air intake. The air intake has more sufficient contact with the molecular sieve, which can improve adsorption efficiency, shorten the nitrogen generation cycle, increase nitrogen generation, and extend the service life of the molecular sieve and the overall equipment.
