Description

Technical Field

[0001] The invention relates to the technical field of steam special effect generating equipment, in particular to a steam special effect nozzle and a steam special effect system. Background Art

[0002] Currently, the steam special effects technology on the market is generally achieved using two technologies: using real steam and using simulated steam.

[0003] Real steam is produced by directly heating water with a traditional electric or gas-fired steam boiler, and then storing the high-temperature and high-pressure steam in a pressure vessel, waiting to be released through a pressure or flow control valve when needed. This method produces steam with temperature and humidity, which can give the audience a very shocking live effect. However, this technology has low energy efficiency, wastes a lot of energy, and only relies on the pressure of the steam itself to be discharged from the special effects nozzle, so in order to increase the pressure, more energy needs to be provided to generate the required pressure. The general traditional steam special effects system needs to store steam at a pressure of about 5kg / cm2, which means that the water temperature in the boiler and the temperature of the entire system need to be maintained at about 159 degrees Celsius, and higher temperatures also mean higher heat loss.

[0004] Simulating steam uses a special effects smoke machine to generate a large amount of smoke to imitate steam by evaporating a solution containing glycerin through a heating tube. Since the smoke generated by a solution containing glycerin can stay in the air for a long time, a very dense steam special effect can be produced with relatively little energy. But it also has disadvantages. Since the fog droplets in the air contain oil that is not easy to evaporate, it takes a relatively long time for the smoke to dissipate. In a shorter special effects performance cycle, the smoke left over from the previous performance cycle will affect the effect of the next performance cycle. The steam special effects produced only use a small amount of heat energy to produce, lacking the temperature of real steam, and cannot meet the special effects requirements of certain themes. In addition, the smoke produced will have the sweetness of glycerin, which affects the audience's experience of the special effects. Long-term inhalation will have health risks and will also pollute the performance scene. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] Figure 1 The present invention provides a structural schematic diagram of a steam special effect nozzle, which includes a condensation chamber 1, a first ejection structure, and a second ejection structure. One end of the condensation chamber 1 is connected to the steam pipe 2, and the other end is connected to the second ejection structure. The first ejection structure is arranged in the condensation chamber 1.

[0028] The first ejection structure reduces the temperature of the steam in the condensation chamber 1, liquefies it into micro-droplets, and at the same time pushes the micro-droplets out of the condensation chamber 1, so that the condensation chamber 1 is in a negative pressure state, and then ejects the steam in the steam pipe 2. The micro-droplets rushing out of the condensation chamber 1 enter the second ejection structure, and expand in volume under the action of the second ejection structure and then erupt to the outside.

[0029] Specifically, the condensation chamber 1 is a cavity with an air inlet and an air outlet, and the shape of the condensation chamber 1 is not limited, and any shape of the cavity is acceptable, for example, a rectangular parallelepiped, a cube, a cylinder, or a prism.

[0030] The condensation chamber 1 is connected to the steam pipe 2, and the steam in the steam pipe 2 can spontaneously enter the condensation chamber 1. However, if it relies solely on the pressure of the steam itself, the speed at which it moves in the steam pipe 2 is very slow, and the amount of mist discharged into the environment is too small to meet the needs of use. It is usually necessary for the steam supply end to consume a lot of energy to increase the steam generation speed, which wastes a lot of energy.

[0031] The first ejection structure has the functions of condensation and ejection at the same time, that is, it cools down the steam in the condensation chamber 1 to liquefy it into micro droplets, and at the same time drives the micro droplets to rush out of the condensation chamber 1. The negative pressure of the condensation chamber 1 sucks the steam in the steam pipe 2 to accelerate its flow speed.

[0032] The first ejection structure is an air nozzle 3, which includes an air nozzle body, an air inlet end, and an air outlet end. The air nozzle body is a strip cavity or an arc cavity with a certain length, and the air inlet end and the air outlet end are respectively located at the two ends of the strip cavity or the arc cavity. The air nozzle body is arranged in the condensation cavity 1, and its air inlet end is connected to the external air supply device, and the air outlet end faces the second ejection structure. The air nozzle 3 and the condensation cavity 1 are detachably connected for easy replacement.

[0033] The gas supply device supplies gas to the air nozzle 3. The temperature and pressure of the gas can be adjusted according to the amount of mist to be generated and the surrounding environment. However, the gas should be lower in temperature than the steam so as to atomize the steam.

[0034] The pressurized gas ejected from the air nozzle 3 has a very fast flow rate, thus generating turbulence, which can fully mix the gas and steam and improve the conversion rate of steam into micro-droplets. In addition, the gas pushes the micro-droplet group located in front of it in the condensation chamber 1 to move quickly, so that it enters the second injection structure at a very fast speed. Negative pressure is generated behind the air nozzle 3, and new steam is injected into the condensation chamber 1.

[0035] In short, gas turbulence causes steam to be quickly and fully atomized into micro droplets, and drives the micro droplets to move quickly, thus generating a large amount of fog in a short period of time. The fog has a high density and high visibility, giving the external environment a shocking visual effect like smoke and fog, like a fairyland.

[0036] The second ejection structure receives micro-droplet clusters with a higher flow rate from the condensation chamber 1, and the second ejection structure further condenses the micro-droplet clusters to fully liquefy the steam mixed therein, and the second ejection structure further increases the volume and flow rate of the micro-droplet clusters to quickly eject them into the external environment. The micro-droplet clusters expand, which can further increase the amount of mist.

[0037] The second ejection structure includes a nozzle body 4 , a venturi tube 5 , and a reversing tube 6 .

[0038] The nozzle body 4 is a cavity with an air outlet at the front end and an air inlet at the rear end. The air inlet is connected to the condensation chamber 1. The air outlet is used to spray mist to the outside. The rear end of the cavity is also provided with multiple air suction holes.

[0039] The venturi tube 5 is disposed in the nozzle body 4, and its air inlet end and air outlet end are respectively facing the air inlet and air outlet of the nozzle body 4. The shape and structure of the venturi tube 5 can be any shape and structure in the prior art, as long as it has the function of generating negative pressure, therefore, simple modification and replacement of the venturi tube 5 is also included in the protection scope of the present application.

[0040] The micro-droplets sprayed from the condensation chamber 1 enter the nozzle body 4, and the venturi tube 5 located in the nozzle body 4 increases the flow rate of the micro-droplets entering therein to produce a negative pressure effect. The negative pressure effect not only induces the micro-droplets in the condensation chamber 1, accelerates the flow rate of the micro-droplets, and further strengthens the negative pressure effect in the condensation chamber 1, but also allows the air in the external environment to enter the nozzle body 4 through the suction holes opened on the nozzle body 4 under the action of negative pressure. The air entering the nozzle body 4 is mixed with the micro-droplets in the nozzle body 4, and the micro-droplets are liquefied for the second time, so that the steam mixed therein is fully liquefied into micro-droplets, thereby increasing the volume of the mist, so that the nozzle body 4 discharges a large amount of dense white mist in a short time, producing an excellent visual effect.

[0041] It should be noted that the mist sprayed from the condensation chamber 1 has a high flow rate due to being accelerated by the first ejection structure. Therefore, after entering the venturi tube 5, the negative pressure effect of the venturi tube 5 is enhanced, making the venturi tube 5 have a better negative pressure effect.

[0042] The reversing tube 6 includes a connecting portion and a reversing portion, the connecting portion and the reversing portion are interconnected, the end of the connecting portion is connected to the nozzle body 4, the end of the reversing portion is a free end, and the mist is sprayed from the free end to the external environment. The spraying direction of the mist can be changed by changing the direction of the free end according to needs. The angle α between the connecting portion and the reversing portion is -90°<α<90°

[0043] The ratio of the inner diameters of the condensing chamber 1, the air jet nozzle 3 and the throat of the venturi tube 5 is 1:0.16:3.

[0044] In summary, the first ejection structure promotes the flow of steam in the condensation chamber 1 and creates negative pressure to accelerate the outflow of steam in the ejection steam pipe 2. The second ejection structure uses the first ejection structure to accelerate the gas for the second time. With the first acceleration, the steam condenses into micro-droplets. With the second acceleration, the micro-droplets expand in volume. The two actions cooperate with each other, which not only increases the mist output speed, but also creates a denser white mist, with a more realistic and shocking visual effect.

[0045] Please refer to Figure 2 The steam special effect system includes a steam pipe 2, one end of the steam pipe 2 is connected to the steam generator, and the other end is connected to the condensation chamber 1. The steam pipe 2 is provided with a safety valve 7, a drain valve 8, and a steam quantity control valve 9.

[0046] The steam special effect system further includes a gas supply pipeline 10, one end of which is connected to a gas source and the other end is connected to the first ejection structure. The gas source is a device or equipment for generating compressed air. The gas supply pipeline 10 is provided with a gas pressure regulator 11 and an air volume control valve, and the air volume control valve includes a ball valve 12, a needle valve 13 and an air solenoid valve 14.

[0047] Working principle:

[0048] The first ejection structure pushes the micro-droplet group inside it to move quickly, and negative pressure is generated in the condensation chamber 1 to eject the steam in the steam pipe 2. The micro-droplet group is ejected from the condensation chamber 1 and enters the second ejection structure. Due to the negative pressure, a second ejection occurs again, and the steam is ejected from the second ejection structure at a very high speed. Along with the first ejection, the first ejection structure atomizes the steam into a high-density micro-droplet group, and along with the second ejection, the second ejection structure increases the volume of the high-density micro-droplet group. Therefore, the steam special effect nozzle and steam special effect system provided by the present invention can provide enough mist for users in a short time, and compared with the prior art, it is more energy-saving and environmentally friendly.

[0049] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
