Description

Technical Field

[0001] This utility model relates to the field of injectors, specifically to an adaptive air volume injection nozzle. Background Technology

[0002] Adsorption dryers are widely used in the drying process of compressed gases. To lower the dew point of the gas, the desiccant usually needs to be regenerated in a timely manner. During the regeneration process, a portion of the gas that has already been treated in the drying zone is often introduced into the regeneration zone to regenerate the adsorbed desiccant. To optimize the recovery process of the regenerated gas and achieve zero gas consumption, this regenerated gas must be reintroduced into the drying zone for further drying, because the regenerated gas usually contains a large amount of moisture.

[0003] When gas passes through the desiccant, it encounters significant resistance, resulting in a substantial pressure drop. This causes the humid, hot gas supplied by the air compressor to typically have a higher pressure, while the gas pressure after passing through the regeneration zone is relatively lower. This pressure difference prevents the regenerated gas from effectively mixing with the humid, hot gas from the air compressor. To address this issue, an ejector is typically installed. When the humid, hot gas flows through the ejector at high speed, the resulting negative pressure draws in the regenerated gas, thus mixing the two. See Chinese Invention Patent Publication No. CN119588124A.

[0004] However, the injector flow rate in existing technologies is fixed. When using a variable frequency compressor, the amount of gas it produces fluctuates with changes in the end-user gas consumption. This results in the regeneration gas not being effectively drawn in and mixed, thus affecting the regeneration effect of the desiccant and consequently causing the dryer to fail to meet the low dew point requirements. Utility Model Content

[0005] To address this issue, this invention provides an adaptive air volume injection nozzle, which mainly solves the technical problem that the flow rate of the existing injectors is fixed and cannot be changed according to the air volume, resulting in the inability to effectively draw in and mix the regenerated gas.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adaptive gas volume injection nozzle includes a first channel and a second channel that are perpendicularly intersected; an injection tube is coaxially arranged on the left side of the inner hole of the first channel; a first conical tube, a connecting tube, and a second conical tube are sequentially connected coaxially to the right end of the first channel; the small-diameter ends of the first and second conical tubes are respectively connected to the left and right ends of the connecting tube; the injection tube includes a conical injection tube disposed on the left side of the inner hole of the first channel; the small-diameter end of the injection tube is connected to a collecting tube; the right end of the collecting tube can movably pass through the first channel and extend into the first conical tube; it also includes a flow meter, a control unit, and a linear motor for collecting the gas flow rate in the injection tube; the first conical tube... The side wall is provided with an insertion part; the insertion part has a through insertion hole; the telescopic arm of the linear motor is connected to a push column; the end of the push column away from the linear motor can be movably inserted into the insertion hole, and a gate plate is connected thereon; the outer wall of the collecting pipe has a gate plate groove communicating with its inner hole; the end of the gate plate away from the push column can be movably inserted into the gate plate groove for adjusting the cross-sectional area of ​​the inner hole of the collecting pipe; the control unit is electrically connected to the flow meter and the linear motor respectively, obtains the gas flow value collected by the flow meter, and drives the linear motor to move closer to or away from the collecting pipe so that the gate plate can adjust the cross-sectional area of ​​the inner hole of the collecting pipe.

[0008] Preferably, a sealing ring is provided between the push post and the wall of the insertion hole.

[0009] Optionally, a first mounting flange is provided on the left side of the first channel; an annular fixing part is provided on the left side of the injection pipe; the fixing part is fixedly connected to the first mounting flange.

[0010] Optionally, a second mounting flange is provided on the right side of the second tapered tube.

[0011] Optionally, a third mounting flange is provided at the top of the second channel.

[0012] Optionally, a fourth mounting flange is provided at the bottom of the second channel.

[0013] Preferably, a protective sleeve is provided on the outside of the first tapered tube, the connecting tube, and the second tapered tube.

[0014] This utility model has at least the following beneficial effects:

[0015] The system comprises a flow meter, a control unit, and a linear motor for collecting the gas flow rate within the injection pipe. An insertion section with an insertion hole is located on the side wall of the first tapered tube. A push column is connected to the telescopic arm of the linear motor, with one end of the push column extending into the insertion hole and connected to a gate. A gate slot communicating with the inner bore of the collecting pipe is located on the outer wall of the collecting pipe, with the other end of the gate extending into the gate slot. By extending and retracting the gate, the system blocks the inner bore of the collecting pipe, thereby adjusting the cross-sectional area of ​​the inner bore and controlling the gas flow rate. The control unit is electrically connected to both the flow meter and the linear motor, acquiring the gas flow rate value collected by the flow meter and driving the linear motor to move closer to or away from the collecting pipe, thus allowing the gate to adjust the cross-sectional area of ​​the inner bore of the collecting pipe. In this way, the flow meter collects the gas flow rate in the injection pipe, and the control unit obtains the collected value in real time. When the gas flow rate decreases, that is, the compressor discharge volume decreases, the control unit drives the linear motor to move away from the manifold, the gate reduces the obstruction of the manifold inner hole, and increases the cross-sectional area of ​​the manifold inner hole. When the gas flow rate increases, that is, the compressor discharge volume increases, the control unit drives the linear motor to move towards the manifold, the gate increases the obstruction of the manifold inner hole, and decreases the cross-sectional area of ​​the manifold inner hole. This obtains a relatively stable gas flow rate to ensure that the system regeneration gas is stably drawn in and mixed.

[0016] Therefore, the adaptive gas volume injection nozzle of this application has the advantage of automatically adjusting the flow rate according to the gas volume, thereby obtaining a relatively stable gas flow rate to ensure that the system regeneration gas is stably drawn in and mixed.

Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0028] This utility model provides an adaptive air volume injection nozzle, such as... Figures 1 to 4As shown, a first channel 1 and a second channel 2 are provided, which are perpendicularly intersecting each other and forming an integrated structure. A jet pipe 6 is coaxially located on the left side of the inner hole of the first channel 1. A first tapered pipe 4, a connecting pipe 3, and a second tapered pipe 5 are sequentially connected coaxially to the right end of the first channel 1. The small-diameter ends of the first tapered pipe 4 and the second tapered pipe 5 are respectively connected to the left and right ends of the connecting pipe 3, and they can be welded together. The jet pipe 6 includes a tapered injection pipe 602 located on the left side of the inner hole of the first channel 1. A collecting pipe 601 is connected to the small-diameter end of the injection pipe 602. The right end of the collecting pipe 601 can movably pass through the first channel 1 and extend into the first tapered pipe 4. A flow meter, a control unit, and a linear motor 7 are also provided for collecting the gas flow rate in the injection pipe 602. An insertion part 401 is provided on the side wall of the first tapered pipe 4, and a through insertion hole 4011 is opened in the insertion part 401. The telescopic arm of the linear motor 7 is connected to a push column 8. The end of the push column 8 furthest from the linear motor 7 can extend movably into the insertion hole 4011, and a gate 10 is connected to it. A gate groove communicating with its inner hole is formed on the outer wall of the manifold 601. The end of the gate 10 furthest from the push column 8 can extend movably into the gate groove. By extending and retracting the gate, it blocks the inner hole of the manifold 601, thereby adjusting the cross-sectional area of ​​the inner hole and controlling the airflow rate. The control unit is electrically connected to the flow meter and the linear motor 7 respectively, obtains the gas flow rate value collected by the flow meter, and drives the linear motor 7 to move closer to or away from the manifold 601, so that the gate 10 adjusts the cross-sectional area of ​​the inner hole of the manifold 601.

[0029] Preferably, in order to seal the push column 8 and prevent gas leakage, a sealing ring 9 is provided between the push column 8 and the wall of the through hole 4011.

[0030] Optionally, this application provides a preferred embodiment in which the injection pipe 602 and the first channel 1 are fixedly connected. Specifically, a first mounting flange 11 is provided on the left side of the first channel 1, and an annular fixing part 603 is provided on the left side of the injection pipe 602. The fixing part 603 is fixedly connected to the first mounting flange 11. Meanwhile, the first mounting flange 11 can also be used for installation on a pipeline when the nozzle of this application is used.

[0031] Preferably, for ease of installation during application, a second mounting flange 12 is provided on the right side of the second tapered tube 5; at the same time, a third mounting flange 13 is provided at the top of the second channel 2 and a fourth mounting flange 14 is provided at the bottom of the second channel 2.

[0032] Preferably, in order to protect the first conical tube 4, the connecting tube 3 and the second conical tube 5, a protective sleeve 15 is provided on the outside of the first conical tube 4, the connecting tube 3 and the second conical tube 5.

[0033] The working principle of this embodiment is as follows:

[0034] The flow meter collects the gas flow rate in the injection pipe, and the control unit acquires this value in real time. When the gas flow rate decreases, i.e., the compressor discharge volume decreases, the control unit drives the linear motor to move away from the manifold, reducing the obstruction of the gate plate on the inner hole of the manifold and increasing the cross-sectional area of ​​the inner hole. When the gas flow rate increases, i.e., the compressor discharge volume increases, the control unit drives the linear motor to move towards the manifold, increasing the obstruction of the gate plate on the inner hole of the manifold and reducing the cross-sectional area of ​​the inner hole. This achieves a relatively stable gas flow rate to ensure that the regeneration gas in the system is stably drawn in and mixed.

[0035] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present application.
