Description

Technical Field

[0001] This utility model relates to the field of air separation equipment technology, specifically to a nitrogen-generating air separation waste gas recovery device. Background Technology

[0002] In the production processes of industries such as chemical, food, electronics, and metallurgy, nitrogen-generating air separation equipment separates nitrogen from the air to provide protective gas and purging gas for production. A typical nitrogen-generating air separation waste gas recovery unit consists of a waste gas collection system, a gas purification unit, a gas separation module, a compression and storage device, and an intelligent control system. The waste gas collection system collects the waste gas discharged from the nitrogen-generating air separation equipment through pipelines and fans. The gas purification unit includes filters, adsorption towers, and other equipment to remove dust, oil, and impurities from the waste gas. The gas separation module uses pressure swing adsorption (PSA) or membrane separation technology to separate and purify components such as oxygen and argon in the waste gas. The compression and storage device compresses and stores the recovered useful gases for reuse in the production process. The intelligent control system monitors parameters such as pressure, flow rate, and composition of each stage in real time and automatically adjusts the equipment's operating status.

[0003] However, the above-mentioned equipment has obvious shortcomings in use. The connecting parts in the recovery equipment of traditional devices mostly adopt static sealing methods. After long-term use, gaps are easily formed due to wear and thermal expansion and contraction, resulting in exhaust gas leakage. This not only wastes resources but also poses safety hazards. In view of this, we propose a full nitrogen-generating air separation exhaust gas recovery device. Utility Model Content

This component, in conjunction with a hydraulic device, drives the slide plate to move up and down along the limit block. The limit rod ensures the accuracy of movement. A motor drives the slide cylinder to rotate via a universal joint.

One end of a first universal joint 36 is fixedly mounted on the output end of the first motor 35. A slide cylinder 37 is fixedly mounted on the other end of the first universal joint 36. A slide rod 38 is slidably mounted on the slide cylinder 37. A limit groove 39 is provided on slide 7. A limit strip 310 is fixedly installed on slide rod 38. One end of lower universal joint 311 is fixedly installed on slide rod 38. A second motor 312 is fixedly installed on slide plate 32. A power gear 313 is fixedly installed on the second motor 312. An auxiliary gear 314 is fixedly installed on slide plate 32. An upper half gear 315 is fixedly installed on slide plate 32. One end of a hinge rod 316 is hingedly installed on slide plate 32. An adjusting plate 317 is hingedly installed on the other end of hinge rod 316. A lower half gear 318 is fixedly installed on adjusting plate 317. A... A limiting slide box 319 has a slider 320 slidably mounted on it. A connecting rod 321 is fixedly mounted at the other end of a lower universal joint 311. A polygonal prism 322 is fixedly mounted on the connecting rod 321. A bent pipe 323 is located below the limiting slide box 319. A funnel frame 329 is fixedly mounted at one end of the bent pipe 323, and a corrugated pipe 324 is fixedly mounted at the other end. A duct fan 325 is fixedly mounted at the other end of the corrugated pipe 324, and the other end of the duct fan 325 is connected to a compressor. An adsorption box 326 is rotatably mounted inside the funnel frame 329. The adsorption box 326... A connecting column 327 is fixedly installed, and a polygonal groove 328 is formed on the connecting column 327. The connecting rod 321 passes through the slider 320 and the bend 323. The polygonal prism 322 is set inside the bend 323. The limiting strip 310 slides inside the limiting groove 39. The polygonal prism 322 is set directly above the connecting column 327 and the polygonal groove 328. The cross-section of the polygonal prism 322 is the same size as the cross-section of the polygonal groove 328. The opening of the polygonal groove 328 on the connecting column 327 adopts an arc-shaped rounded corner design. The power gear 313 meshes with the auxiliary gear 314, and the upper half gear 315 meshes with the lower half gear 318.

[0020] In this embodiment, the mounting plate 1 serves as the basic component, and the first hydraulic device 31 fixed on it is the power source for the movement of the adjustment component 3. The piston end of the first hydraulic device 31 is connected to the slide plate 32. After starting, it can drive the slide plate 32 to move up and down along the limit block 33. The limit rod 34 on the slide plate 32 ensures the accuracy during the movement and prevents deviation. After the first motor 35 on the slide plate 32 starts, it drives the slide cylinder 37 to rotate through the first universal joint 36. The slide rod 38 is slidably installed in the slide cylinder 37. The limiting groove 39 on the slide bar 38 cooperates with the limiting strip 310 on the slide bar 38 to restrict the axial movement of the slide bar 38, so that it can only slide linearly within the slide cylinder 37 or rotate synchronously with the slide cylinder 37. The lower end of the slide bar 38 is connected to the connecting rod 321 through the lower universal joint 311, thereby driving the connecting rod 321 and the polygonal prism 322 on it to move. At the same time, the second motor 312 on the slide plate 32 drives the power gear 313 to rotate. The power gear 313 meshes with the auxiliary gear 314, and the auxiliary gear 314 drives the upper half When gear 315 rotates, the upper gear 315 meshes with the lower gear 318 on the adjusting plate 317, causing the adjusting plate 317 to swing via the hinge rod 316. This, in turn, drives the limiting slide box 319 and the slider 320 to adjust their positions. When the adsorption box 326 needs to be operated, the aforementioned movement causes the polygonal prism 322 to be accurately inserted into the polygonal groove 328 of the connecting column 327. Subsequently, the polygonal prism 322 rotates, causing the connecting column 327 and the adsorption box 326 to rotate within the funnel frame 329, thus adsorbing the material. The combined motion prepares for waste gas recovery. Then, the duct fan 325 is started, and the negative pressure generated by it acts on the funnel frame 329 and the gas storage tank 2 through the corrugated pipe 324 and the bend 323. At this time, the polygonal prism 322 rotates, driving the adsorption box 326 to rotate. The waste gas passes through the adsorption box 326 under the action of negative pressure, and the impurities and harmful components in it are treated by the adsorption material. Finally, the treated waste gas is transported to the gas storage tank 2 through the duct fan 325 for further treatment, completing the entire waste gas recovery process.

[0021] In one embodiment of this utility model, an auxiliary component 4 is provided on the limiting slide box 319. The auxiliary component 4 includes an installation ring 41. The installation ring 41 is fixedly installed on the bent pipe 323. A first hinge frame 42 is fixedly installed on the installation ring 41.

The installation ring 41 is located directly above the funnel frame 329.

[0022] In this embodiment, the mounting ring 41 fixed on the bend 323 serves as the basic connecting component of the auxiliary component 4. The first hinge frame 42 on the mounting ring 41 and the second hinge frame 45 on the mounting block 44 on the limiting slide box 319 are connected to the hydraulic rod 47 through the first connecting block 43 and the second connecting block 46, respectively, so that the bend 323, the limiting slide box 319 and the hydraulic rod 47 form a triangular stable structure. When the hydraulic rod 47 extends or retracts, it can drive the limiting slide box 319 to adjust the tilt angle of the bend 323, ensuring that the funnel frame 329 is tightly fitted with the opening of the gas storage tank 2. The funnel frame 329 is installed at the opening of the gas storage tank 2 by snap-fit. With the thrust of the hydraulic rod 47, the adsorption box 326 and the opening of the tank form a negative pressure seal to prevent exhaust gas leakage. At the same time, it is easy to quickly disassemble and maintain the adsorption box 326.
