Description

Technical Field

[0001] This utility model relates to the field of injectors, specifically to an 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 ejector flow rate in existing technologies is fixed, and an ejector with a suitable flow rate must be selected based on process requirements. Therefore, when replacing an air compressor with a different flow rate later, the ejector must also be replaced, which not only increases the workload of replacement but also leads to higher replacement costs. Utility Model Content

[0005] Therefore, this utility model provides a spray nozzle, which mainly solves the technical problem that the existing spray nozzles are not adaptable and require replacement with a new spray nozzle when the flow rate of the dryer changes, resulting in a large workload and high replacement cost.

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

[0007] A spray nozzle includes a first channel and a second channel that are perpendicularly intersected; the right end of the second channel is coaxially connected to a first conical tube, a connecting tube, and a second conical tube; the small-diameter ends of the first and second conical tubes are respectively connected to the left and right ends of the connecting tube; a spray tube is detachably connected coaxially to the left side of the inner hole of the second channel; the spray tube includes a conical injection tube detachably connected to the left side of the inner hole of the second channel; the small-diameter end of the injection tube is connected to a collecting tube; the inner hole of the collecting tube has a preset aperture; the right end of the collecting tube can movably pass through the second channel and extend into the first conical tube.

[0008] Optionally, a first mounting flange is provided on the left side of the second 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.

[0009] Preferably, a sealing ring is provided between the fixing part and the first mounting flange.

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

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

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

[0013] This utility model has at least the following beneficial effects:

[0014] It features a detachable injection pipe coaxially connected to the left side of the second channel's inner bore. The injection pipe includes a tapered injection pipe detachably connected to the left side of the second channel's inner bore. The smaller diameter end of the injection pipe is connected to a manifold, the inner bore of which has a preset diameter. This allows for easy replacement of the air compressor by replacing only the compatible injection pipe, eliminating the need to replace the entire injector. This reduces workload, speeds up replacement, and lowers product costs.

[0015] Therefore, the spray nozzle of this application has the advantages of reducing the amount of construction work, speeding up the replacement efficiency, and also reducing product costs. Attached Figure Description

[0022] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0024] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. 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.

[0025] This utility model provides a spray nozzle, such as... Figure 1 , Figure 2 As shown, a first channel 1 and a second channel 2 are provided, which are perpendicularly intersecting each other. A first tapered tube 5, a connecting tube 4, and a second tapered tube 6 are coaxially connected sequentially to the right end of the second channel 2. The small-diameter ends of the first tapered tube 5 and the second tapered tube 6 are connected to the left and right ends of the connecting tube 4, respectively, and they can be welded together. A jet pipe 3 is detachably connected coaxially to the left side of the inner hole of the second channel 2. The jet pipe 3 includes a tapered injection pipe 302 detachably connected to the left side of the inner hole of the second channel 2. The small-diameter end of the injection pipe 302 is connected to a collecting pipe 301. The inner hole of the collecting pipe 301 has a preset orifice diameter to accommodate different flow rates. The right end of the collecting pipe 301 can movably pass through the second channel 2 and extend into the first tapered tube 5. Thus, when replacing the air compressor, only the compatible jet pipe 3 needs to be replaced, without replacing the entire injector, reducing the amount of work, speeding up the replacement process, and also lowering product costs.

[0026] Optionally, this application provides a preferred embodiment in which the injection tube 302 and the second channel 2 are detachably connected. Specifically, a first mounting flange 7 is fixedly installed on the left side of the second channel 2, and an outwardly protruding annular fixing part 303 is provided on the left side of the injection tube 302. The fixing part 303 and the first mounting flange 7 are fixedly connected together by bolts.

[0027] Preferably, a sealing ring is provided between the fixing part 303 and the first mounting flange 7 to seal the injection pipe 302 and the second channel 2 and prevent gas leakage.

[0028] Preferably, for ease of installation during application, a second mounting flange 8 is provided on the right side of the second tapered tube 6; at the same time, a third mounting flange 9 is provided at the top of the first channel 1 and a fourth mounting flange 10 is provided at the bottom of the first channel 1.

[0029] 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.
