Description

Technical Field

[0001] The present disclosure relates to the technical field of ejectors, and in particular to an ejector with integrated spraying and cooling. Background Art

[0002] In order for ground test equipment such as engine supersonic test benches to operate smoothly, exhaust equipment needs to be installed to extract the airflow in the test equipment at low pressure and discharge it into the atmosphere. Ejectors, as a type of mainstream exhaust equipment, are widely used in this type of test equipment. Since the exhaust of ground test equipment such as test benches is a mixture of the high-temperature airflow of the supersonic flow field and the exhaust gas from the engine tail nozzle, the temperature is relatively high, exceeding the temperature resistance limit of existing materials, resulting in the ejector being unable to operate in this environment without cooling. Therefore, the airflow needs to be cooled by the exhaust cooling system before it can be passed into the ejector.

[0003] According to the structure, the ejector can be divided into: annular ejector, central nozzle ejector and multi-nozzle ejector; the ejection airflow of the annular ejector is arranged on the ejector wall in the form of an annular channel, so that the low-temperature ejection airflow can form an air film, thereby effectively protecting the inner wall of the ejector from being damaged by the high-temperature airflow, but it is difficult to be applied to large ejectors due to the problem of machining co-circular accuracy; the ejection airflow of the central nozzle ejector is arranged in the center of the ejector channel with a nozzle, but due to the influence of mixing efficiency, its length and size are very long, and since it does not have the wall air film protection similar to the annular ejector, the ejector wall needs to be equipped with a water cooling mechanism, so it is long in size and the economic benefit of adding jacket water cooling is low; the multi-nozzle ejector also does not have wall air film protection, but the design of the multi-nozzle makes it shorter in size and has high ejection efficiency, so it can be used in various ejectors.

[0004] The airflow needs to be cooled before it is connected to the ejector. Commonly used cooling equipment includes convection heat exchange coolers and spray cooling systems. The scale, floor space and construction cost of convection heat exchange coolers are much higher than those of spray cooling water systems. At the same time, the pressure loss is also much greater than that of spray cooling water systems. Therefore, they are generally not used in large supersonic engine test benches. Although the spray cooling system has low cost and low pressure loss, in order to ensure the effectiveness of spray mixing, the length of the spray cooling section is generally 5 to 10 times its diameter, resulting in its length is still very long. For large engine test benches, a large area is still required.

[0005] In view of this, there is an urgent need for an ejector with a new structure in the market to solve the problems of high cost and large floor space occupied by the ejector in the prior art. Summary of the invention

[0044] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0045] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0046] Combination Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present disclosure provides a spray cooling integrated ejector, which includes an ejector body 1, an ejector system 2 and a spray system 3; the ejector system 2 is arranged at the periphery of the ejector body 1, and includes an air collecting ring 21 and an ejector nozzle 22 which are interconnected; the spray system 3 is arranged at the periphery of the ejector body 1, and includes a water collecting ring 31 and a spray pipe 32 which are interconnected;

[0047] Among them, the other end of the ejector nozzle 22 is located in the ejector body 1 and is bent and extended along the ejection direction; the other end of the spray pipe 32 is located in the ejector body 1 and is arranged immediately upstream of the ejector nozzle 22 along the ejection direction; an atomizing nozzle 321 is also provided in the pipe section of the spray pipe 32 located in the ejector body 1.

[0048] The spray cooling integrated ejector provided in the embodiment of the present disclosure can be specifically but not limited to being applied to exhaust equipment in ground test sites such as engine supersonic test benches. This example is used to explain the use process.

[0049] When the spray cooling integrated ejector is used, the inlet section of the ejector body 1 is first connected to the exhaust equipment, and the outlet section of the ejector body 1 is connected to the external environment. When the exhaust is ejected, pressurized air is supplied to the ejector nozzle 22 through the air collecting ring 21 in the ejection system 2. Since the other end of the ejector nozzle 22 is located in the ejector body 1 and is bent and extended along the ejection direction, the other end of the ejector nozzle 22 can be used as a high-speed discharge end of the ejection airflow, so that the airflow in the ejector body 1 can be ejected and discharged along the ejection direction.

[0050] Moreover, the spray system 3 can also work synchronously when the ejection system 2 is working, and pressurize water supply to the spray pipe 32 through the water collecting ring 31, so that the spray pipe 32 is located at the other end of the ejector body 1, and the atomizing nozzle 321 can atomize the high-pressure water flow and spray it out at high speed. Since the spray pipe 32 is arranged immediately upstream of the ejection nozzle 22 along the ejection direction, the water mist sprayed by the spray pipe 32 can be mixed and cooled with the high-temperature airflow entering the inlet section of the ejector body 1, and the water-gas mixture after mixing and cooling can also be quickly ejected to the outlet section of the ejector body 1 along the ejection system 2, effectively preventing the high-temperature airflow from burning the ejection nozzle 22 and the inner wall of the ejector body 1. The spray cooling integrated ejector has the beneficial effects of simple structure, small footprint, high efficiency of spray cooling, and low engineering cost.

[0051] It is also worth noting that the air collecting ring 21 in the above-mentioned injection system 2 and the water collecting ring 31 in the spray system 3 can be specifically set to be single or multiple, and the air collection capacity of the air collecting ring 21 and the water collection capacity of the water collecting ring 31 can be adapted and set according to the requirements of the site size.

[0052] In one embodiment, windward plates 221 are respectively disposed on both sides of the ejection nozzle 22 and the spray pipe 32; the two windward plates 221 are connected to each other at an acute angle and are disposed opposite to the ejection direction.

[0053] Specific, combined Figure 4 In further detail, windward plates 221 are respectively provided on both sides of the ejector nozzle 22 and the spray pipe 32, and the windward plates 221 can be arranged to be connected with each other at an acute angle, and the windward plates 221 can be fixedly installed by welding to the ejector nozzle 22 or the spray pipe 32. Moreover, the acute angle ends formed by the two windward plates 221 are arranged to face the ejection direction, so that the wind resistance of the ejector nozzle 22 and the spray pipe 32 can be reduced, so that a faster ejection airflow can be formed inside the ejector body 1.

[0054] The specific arrangement of the windward plate 221 has the beneficial effects of simple structure, reduced wind resistance, and increased air flow velocity inside the ejector body 1.

[0055] In one embodiment, the atomizing nozzle 321 includes a straight-injection nozzle, a solid cone single-phase atomizing nozzle and a fan-shaped single-phase atomizing nozzle; the straight-injection nozzle is arranged at the end of the spray pipe 32; the solid cone single-phase atomizing nozzle is arranged in a direction opposite to the injection direction; the fan-shaped single-phase atomizing nozzle is arranged perpendicular to the windward baffle 221.

[0056] Specific, combined Figure 4 and Figure 5To further explain in detail, the atomizing nozzle 321 is specifically configured as a straight-injection nozzle located at the end of the spray pipe 32, a solid cone single-phase atomizing nozzle arranged in a direction opposite to the injection direction, and a fan-shaped single-phase atomizing nozzle arranged perpendicular to the windward baffle 221. In this way, the three types of nozzles can respectively perform atomization spraying in three different directions, fully ensuring that the surrounding wall and the end of the spray pipe 32 can spray sufficient atomized water mist, ensuring that the water mist can fully mix and cool the high-temperature airflow entering the inlet section of the ejector body 1.

[0057] The specific arrangement of the above-mentioned atomizing nozzle 321 has the beneficial effects of simple structure and capable of atomizing and spraying in a large range and at multiple points.

[0058] In one embodiment, a plurality of ejector nozzles 22 are arranged in a circular array along the peripheral wall direction of the ejector body 1; and at least two ejector nozzles 22 have ejection sections formed by bending along the ejection direction at different radial positions in the ejector body 1.

[0059] Specific, combined Figure 2 and Figure 3 To further explain in detail, at this time, two groups of multiple ejector nozzles 22 are arranged in a circular array along the circumferential wall direction of the ejector body 1, and the ejection sections formed by the two groups of ejector nozzles 22 bent along the ejection direction are staggered in radial positions in the ejector body 1. In this way, the multiple ejector nozzles 22 can evenly eject the ejection airflow at multiple points along the circumference and radial direction of the ejector body 1, thereby generating a sufficiently efficient ejection airflow within a shorter size range.

[0060] The specific arrangement of the above-mentioned ejection nozzle 22 has the beneficial effects of simple structure, saving length and improving the efficiency of ejection airflow.

[0061] In one embodiment, the spray pipe 32 extends radially along the ejector body 1 and is disposed one-to-one with the ejector nozzles 22 ; a plurality of atomizing nozzles 321 are disposed adjacent to each other in a row along the extending direction of the spray pipe 32 .

[0062] Specific, combined Figure 2 and Figure 3 To further explain in detail, multiple spray pipes 32 are respectively extended along the radial direction of the ejector body 1 and are arranged one-to-one with the ejector nozzles 22, and multiple atomizing nozzles 321 are arranged closely and side by side along the extension direction of the spray pipes 32, so that each spray pipe 32 can form a strip-shaped atomization area with a reversing array distribution through the multiple atomizing nozzles 321, so that it can be fully mixed and cooled with the high-temperature airflow ejected from the inlet section of the ejector body 1, and the atomization area can fully cover the ejector nozzles 22 one-to-one along the radial direction of the ejector body 1, thereby effectively preventing the high-temperature airflow ejected from the inlet section of the ejector body 1 from burning the ejector nozzles 22.

[0063] The specific arrangement of the spray pipe 32 has the beneficial effects of simple structure, being able to fully mix with the high-temperature airflow to reduce the temperature, and preventing the ejector nozzle 22 from being burned.

[0064] In one embodiment, a stop valve 222 is provided in the ejection nozzle 22 ; a regulating valve 322 , a pressure gauge 323 and a flow meter 324 are provided in the spray pipe 32 .

[0065] Specific, combined Figure 6 To further explain in detail, a stop valve 222 is provided in the ejector nozzle 22, so that the actual ejection power of the ejector nozzle 22 can be controlled by the stop valve 22 to adapt to different operating conditions; a regulating valve 322, a pressure gauge 323 and a flow meter 324 are provided in the spray pipe 32, so that the actual water flow rate of the spray pipe 32 can be controlled by the regulating valve 322, and the pressure gauge 323 and the flow meter 324 can facilitate intuitive understanding of the water flow information in the spray pipe 32.

[0066] In one embodiment, the air collecting ring 21 and the water collecting ring 31 are respectively configured as circular rings or polygonal rings; the air collecting ring 21 and the water collecting ring 31 are respectively spaced apart on the outer periphery of the ejector body 1, and the water collecting ring 31 is located upstream of the air collecting ring 21 along the ejection direction.

[0067] Specific, combined Figure 1 and Figure 2 To further explain in detail, at this time, the air collecting ring 21 and the water collecting ring 31 are respectively arranged to be regular octagonal rings, and the air collecting ring 21 and the water collecting ring 31 are respectively arranged at intervals on the outer periphery of the ejector body 1, so that the ejector body 1 can better dissipate heat outwards, and the water collecting ring 31 is located upstream of the air collecting ring 21 along the ejection direction, so that the spray system 3 can first cool down the high-temperature airflow in the ejector body 1, and then quickly eject it through the ejection system 2.

[0068] In one possible implementation manner, the spray cooling integrated ejector further includes a water cooling jacket 4; the water cooling jacket 4 is sleeved on the outer peripheral wall of the ejector body 1, and can cool the ejector body 1 by circulating water supply.

[0069] Specific, combined Figure 3To further explain in detail, a water-cooling jacket 4 is also provided on the outer peripheral wall of the ejector body 1, and the water-cooling jacket 4 can cool the ejector body 1 by circulating water supply, so as to prevent a small amount of high-temperature airflow in the ejector body 1 from not being sufficiently cooled by the spray system 3 in a short period of time. When a small amount of high-temperature airflow accidentally causes the ejector body 1 to heat up, the water-cooling jacket 4 can be controlled to circulate water supply according to the actual heating condition of the ejector body 1, thereby performing additional auxiliary water cooling on the ejector body 1 to ensure that the ejector body 1 can always be in a normal and stable working temperature range.

[0070] In one embodiment, the ejector body 1 includes an inlet barrel section 11 and an ejector straight barrel section 12; the diameter of the inlet barrel section 11 is larger than the diameter of the ejector straight barrel section 12, and the two are connected by a conical transition barrel section.

[0071] Specific, combined Figure 3 To further explain in detail, the ejector body 1 is specifically configured to include a large-diameter inlet barrel section 11 and a small-diameter ejector straight barrel section 12, and a conical transition barrel section is passed between the inlet barrel section 11 and the ejector straight barrel section 12, so that the large-diameter inlet barrel section 11 can facilitate the introduction of more initial high-temperature airflow, and can be more convenient for the water mist sprayed by the spray system 3 to be mixed with it for cooling, and the ejection system 2 can also eject the ejection airflow from the small-diameter ejector straight barrel section 12 at a higher speed, so that the mixed and cooled water vapor entering the inlet barrel section 11 can enter the ejection straight barrel section 12 more quickly for discharge.

[0072] In one embodiment, the water-cooling jacket 4 completely wraps around the inlet barrel section 11 , and partially wraps around the barrel of the ejector straight barrel section 12 close to the inlet barrel section 11 .

[0073] Specific, combined Figure 3 To further explain in detail, the water-cooling jacket 4 is completely wrapped around the inlet barrel section 11, and partially wrapped around the barrel of the ejector straight barrel section 12 close to the inlet barrel section 11. This can, on the one hand, minimize the length of the water-cooling jacket 4, and on the other hand, even if a small amount of high-temperature airflow accidentally flows into the front section of the ejector straight barrel section 12 and causes the ejector straight barrel section 12 to heat up, the water-cooling jacket 4 can also cool it down, thereby fully ensuring that the ejector body 1 can always be in a normal and stable operating temperature range.

[0074] In summary, the spray cooling integrated ejector provided in the embodiment of the present invention is based on the ejection principle of a multi-nozzle ejector, and integrates the air film cooling technology of an annular ejector. At the same time, a spray system 3 is added according to structural requirements. By setting a spray pipe 32 and an atomizing nozzle 321 arranged in a ring array in the inlet section of the ejector body 1, water mist is mixed and sprayed to the high-temperature gas in the inlet section of the ejector body 1, so that the high-temperature gas can be mixed and cooled efficiently and quickly. At the same time, the ejector nozzle 22 is protected against high temperature and impact by the spray pipe 32 and the atomizing nozzle 321, so as to finally realize the function of rapid cooling and ejection and discharge of high-temperature gas, and the water-cooling jacket 4 auxiliaryly arranged on the outer periphery of the ejector body 1 can greatly reduce its own length, so as to finally realize the beneficial effects of simple structure, small footprint, efficient spray cooling and low engineering cost.
