Description

Technical Field

[0001] The utility model relates to the technical field related to multi-channel pipes or pipe components made of rigid materials, in particular to a gas-liquid dual-supply injection-type supply pipeline system. Background Art

[0002] As an efficient method of converting liquid water into tiny water droplets suspended in the air, water-liquid atomization technology has been widely used in many fields such as agricultural irrigation, artificial snowmaking, medical assistance and industrial dust reduction.

[0003] Traditional water-liquid atomization generally uses multi-channel pipes or pipe groups with corresponding valves and nozzles to achieve comprehensive treatment of liquid water, so as to achieve the purpose of efficient cutting or atomization of water droplets.

[0004] For example, in the patent document with patent publication number CN210830953U and IPC classification number F16L41 / 02 (20060101), a drip-proof atomizing three-way pipe is disclosed, which includes a water inlet pipe, a high-pressure drip-proof valve, a water outlet pipe, a high-pressure drip-proof valve outer cavity, a high-pressure drip-proof valve inner cavity, a retaining ring and a triangular diversion structure and other main components.

[0005] It can be seen from the records in the above patent documents that when working, it mainly adds a triangular diversion structure at the bottom end of the outer cavity of the high-pressure anti-drip valve to divert the incoming liquid and reduce the impact of the liquid on the inner cavity wall of the high-pressure anti-drip valve.

[0006] However, the atomizing capability of this atomizing three-way pipe structure is relatively weak, and it cannot meet the usage requirements well when dealing with working scenarios with large flow atomization requirements such as artificial snowmaking and large-area industrial dust reduction.

[0007] To this end, the utility model optimizes and improves the problems of small atomization volume and poor atomization effect existing in the multi-pass atomization pipes in the prior art, and specially proposes a gas-liquid dual-supply injection-type supply pipeline system that can meet the needs of large-flow atomization scenarios such as artificial snowmaking and industrial dust reduction, so as to better solve the problems existing in the prior art.

[0011] In any of the above schemes, it is preferred that each of the atomizing nozzles is arranged to be inclined toward the central axis of the bell tube.

[0012] In any of the above schemes, it is preferred that the two atomizing nozzles that are closely arranged on two adjacent annular water pipes are staggered.

[0015] In any of the above schemes, preferably, a protective cover is provided on the periphery of the bell tube, the outer end of the protective cover is detachably fixed to the outer side wall of the end of the bell tube, and the inner end of the protective cover extends to the outside of the end of the large-diameter wind tube.

[0016] In any of the above solutions, it is preferred that the central fan is an axial flow fan.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

DETAILED DESCRIPTION

[0031] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 6 as shown in .

[0032] Embodiment: A gas-liquid dual-supply jet supply pipeline system comprises a large-diameter air duct 1, an atomizing nozzle group is coaxially installed at the outlet end of the large-diameter air duct 1, a relatively fixed multi-channel pipe group is arranged on one side of the large-diameter air duct 1, each water outlet end of the multi-channel pipe group is used to connect with the water inlet corresponding to the atomizing nozzle group, the water inlet end of the multi-channel pipe group is connected to an external high-pressure water source through a water supply pipeline 2, and a central fan 3 is installed at the inlet end of the large-diameter air duct 1, the central fan 3 is used to blow low-temperature airflow to the outlet end of the large-diameter air duct 1 and drive the water mist sprayed by the atomizing nozzle group to quickly guide and cool. The entire gas-liquid dual-supply jet supply pipeline system relies on an external high-pressure water source and a high-pressure gas source to provide water flow and airflow, the water flow enters the multi-channel pipe group through the high-pressure transmission of the water supply pipeline 2, and then enters the atomizing nozzle group under the diversion effect of the multi-channel pipe group, and then relies on each atomizing nozzle 11 to complete the multi-nozzle type atomization treatment. The water flow processed by the atomizing nozzle 11 is directly sprayed outward, and the atomized water droplets are cooled and sprayed outward in cooperation with the wind force of the central fan 3 and the high-pressure airflow, so as to complete artificial snowmaking in low temperature weather.

[0033] In any of the above schemes, it is preferred that the multi-channel pipe group includes a multi-way straight pipe 4 fixedly arranged on one side of the large-diameter wind tube pipe 1, both ends of the multi-way straight pipe 4 are sealed by end covers 5, the water supply pipe 2 is connected to the bottom of the multi-way straight pipe 4, and diversion pipes 6 are respectively installed at each passage pipe opening spaced apart along the length direction of the top of the water supply pipe 2, the water outlet end of each diversion pipe 6 is connected to the water inlet corresponding to the atomizing nozzle group, and a water control valve 7 is respectively installed on each diversion pipe 6.

[0034] It should be noted that the multi-channel pipe group relies on the water supply pipe 2 to receive the high-pressure water source from the outside. The high-pressure water source enters the multi-channel straight pipe 4 through the water supply pipe 2, and then directly passes through each diversion pipe 6 under the diversion effect of the multi-channel straight pipe 4 to flow to the liquid guide channel 10 corresponding to the atomizing nozzle group. The high-pressure water entering the corresponding liquid guide channel 10 is directly atomized under the action of multiple atomizing nozzles 11.

[0035] By controlling the opening and closing of the corresponding water control valve 7, the atomization amount of the water liquid can be quickly controlled, effectively ensuring that it can be applied to different scene requirements of the atomization amount.

[0036] In any of the above schemes, it is preferred that the atomizing nozzle group includes a trumpet tube 8 coaxially welded and installed at the outlet end of the large-diameter wind tube 1, and a plurality of circles of annular water pipes 9 are welded on the curved surface of the outer wall of the trumpet tube 8 at uniform intervals along its axial direction, and a liquid guide channel 10 is formed between the interior of each annular water pipe 9 and the outer wall of the trumpet tube 8, and a diversion pipeline 6 for connecting with the liquid guide channel 10 inside the annular water pipe 9 is respectively arranged on the outer wall of each annular water pipe 9, and a plurality of atomizing nozzles 11 are evenly spaced along the circumference of the curved inner wall of the trumpet tube 8 corresponding to each liquid guide channel 10, and the water inlet end of each atomizing nozzle 11 is connected to the interior of the corresponding liquid guide channel 10.

[0037] It should be noted that when the atomizing nozzle group is working, the high-pressure water flow is directly transported to the liquid guide channel 10 of the corresponding annular water guide pipe 9 by relying on the corresponding diversion pipeline 6. The high-pressure water flow entering the liquid guide channel 10 will be sprayed out through the various atomizing nozzles 11 formed in a circle at the corresponding positions. The liquid passing through the atomizing nozzles 11 will be fully atomized under the action of the atomizing nozzles 11 and then sprayed out.

[0038] In any of the above solutions, it is preferred that each of the atomizing nozzles 11 is arranged to be inclined toward the central axis of the bell tube 8 .

[0039] Setting each atomizing nozzle 11 so that the outlet end is inclined toward the central axis of the bell tube 8 can better ensure the effect of accumulation and gathering when spraying atomized water droplets, effectively ensure the atomizing spraying effect, and facilitate the cooperation with the central fan 3 to complete rapid outward blowing.

[0040] It should be noted that the inclination angles of the various atomizing nozzles 11 located on the circumference of the base circle are the same. This structure can ensure that the various atomizing nozzles 11 on the same circumference can jointly form an annular atomizing spray effect, thereby improving the overall atomizing effect.

[0041] In any of the above solutions, it is preferred that the two atomizing nozzles 11 disposed close to each other on two adjacent annular water pipes 9 are staggered.

[0042] The staggered arrangement of the atomizing nozzles 11 located on different base circles but close to each other can effectively reduce mutual collision when spraying atomized water droplets outward, thereby effectively ensuring the effect of spraying atomized water droplets outward.

[0043] In any of the above schemes, it is preferred that an air supply pipeline 12 connected to an external high-pressure air source is connected to the outer wall of the large-diameter wind tube 1 on one side of the central fan 3, and the central fan 3 is used to guide the low-temperature airflow introduced into the air supply pipeline 12.

[0044] The high-pressure airflow can be introduced into the internal cavity of the corresponding large-diameter wind tube 1 through the air supply pipeline 12, and the low-temperature airflow can be blown outward under the strong blowing action of the central fan 3, simulating the low-temperature weather to blow and cool the atomized water droplets outward, further improving the effect of water mist crystallization cooling, and facilitating improving the efficiency and effect of snow core forming in artificial snowmaking scenarios.

[0045] In any of the above solutions, preferably, a pressure meter 13 for detecting the internal water pressure is installed on the multi-way straight pipe 4.

[0046] By observing the pressure value of the pressure meter 13, it is convenient to observe the current water flow pressure, to control the pressure of the outward spray, and to effectively ensure the atomization effect.

[0047] In any of the above schemes, it is preferred that a protective cover 14 is provided on the periphery of the bell tube 8, the outer end of the protective cover 14 is detachably fixed to the outer end wall of the bell tube 8, and the inner end of the protective cover 14 extends to the outside of the end of the large-diameter wind tube 1.

[0048] The protective cover 14 provided here can effectively play a protective and aesthetic role, and prevent the water mist from being scattered at the mouth of the trumpet tube 8 after being sprayed outwards, causing water accumulation.

[0049] In any of the above solutions, it is preferred that the central fan 3 is an axial flow fan.

[0050] The axial flow fan can better utilize wind force to quickly transport the low-temperature airflow entering the inner cavity of the large-diameter air cylinder tube 1 to the outside, so as to better mix it with the atomized water droplets and improve the crystallization efficiency of the atomized water droplets.

[0051] In any of the above solutions, preferably, the number of liquid conducting channels provided here is 4.

[0052] The four liquid guide channels are provided to supply liquid to each atomizing nozzle 11 on the circumference of the inner wall respectively. When all the atomizing nozzles 11 are started, the atomizing spray amount can be better guaranteed and a layered atomizing spray effect can be formed.

[0053] In any of the above solutions, it is preferred that the adjacent liquid-conducting channels 10 are coaxially arranged and the inner diameter of the inner ring of the liquid-conducting channels 10 arranged from top to bottom increases continuously.

[0054] The multiple liquid guiding channels 10 can better complete the diversion of high-pressure liquid. At the same time, corresponding atomizing nozzles 11 are installed on the inner wall of the bell tube 8 corresponding to each liquid guiding channel 10, which can better ensure the atomization effect when realizing multi-nozzle atomization.

[0055] Specific working principle: The gas-liquid dual-supply injection-type supply pipeline system in the utility model relies on an external high-pressure water source and a high-pressure gas source to provide water flow and air flow.

[0056] The high-pressure water flows into the multi-channel pipe group through the water supply pipe 2, and then enters the atomizing nozzle group under the diversion effect of each diversion pipe 6 of the multi-channel pipe group.

[0057] Finally, multi-nozzle atomization processing is completed by relying on the various atomizing nozzles 11 that are set up; the water flow processed by the atomizing nozzles 11 is directly sprayed outward, and the atomized water droplets are cooled and sprayed outward in conjunction with the wind force of the central fan 3 and the high-pressure airflow, so as to complete artificial snowmaking in low temperature weather.

[0058] When the atomization amount needs to be controlled, the atomization amount of the water liquid can be quickly controlled by controlling the opening and closing of the water control valve 7, effectively ensuring that it can be applied to different scene requirements of the atomization amount.

[0059] In summary, it can be seen that the gas-liquid dual-supply injection supply pipeline system is connected to an external high-pressure water source and a high-pressure gas source when in use, and relies on the external high-pressure water source and the high-pressure gas source to achieve gas-liquid dual supply while completing atomization cooling, which can increase the speed of water mist cooling and crystallization, and is convenient for use in artificial snowmaking scenes.

[0060] Among them, when the designed atomizing nozzle group performs water atomization processing, each liquid guide channel 10 arranged at intervals along the axial direction cooperates with the corresponding atomizing nozzle 11 to complete the water spray in a multi-level spaced annular layout along the axial direction, which effectively improves the efficiency of atomizing the liquid into water droplets and improves the atomization effect. It can be suitable for the large-flow atomization scene requirements of artificial snowmaking.

[0061] During operation, the atomized water can be quickly blown outwards under the action of the high-speed low-temperature airflow at the rear end, thereby further improving the cooling and diversion of the water mist, ensuring the atomization effect of the water mist and improving the efficiency of the water mist condensing into crystals. The designed atomizing nozzles 11 at all levels are installed in the threaded mounting holes corresponding to the inner wall of the trumpet tube 8 in a detachable manner. The overall detachability is strong and can be quickly replaced and repaired as needed; when the high-pressure liquid is supplied, the water supply pipeline 2 is relied on to supply water to the multi-channel straight pipe 4. The liquid can be diverted and transported to each diversion pipeline 6 through the multi-channel straight pipe 4, effectively ensuring the high efficiency of multi-channel pipelines in transporting liquids.

[0062] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model. For technicians in this technical field, any replacement improvements or changes made to the implementation methods of the utility model fall within the protection scope of the utility model.
