Description

TECHNICAL FIELD

[0001] The utility model relates to fluid mixing technical field, concretely relates to a steam -water mixing sound attenuation ejector. BACKGROUND

[0002] In industrial production and daily life, steam-water mixing technology is widely used, for example, in food processing, chemical production, energy conversion and other fields, steam-water mixing equipment is used to realize effective mixing of steam and water to achieve heating, cooling, humidification and other purposes. However, the traditional steam-water mixing equipment has problems such as low mixing efficiency, high energy consumption and loud noise. These problems not only affect production efficiency and product quality, but also have adverse effects on the working environment.

[0003] With the improvement of environmental awareness and the development of technology, the demand for low-noise, high-efficiency steam-water mixing equipment in the market is increasing. Traditional mixing equipment usually uses simple pipeline mixing method, which lacks effective mixing mechanism, leading to the formation of local supersaturation zone and unmixed zone during steam and water mixing, resulting in uneven mixing. In addition, under high pressure and high speed conditions, a large amount of noise is generated during steam-water mixing, which not only affects the use experience of the equipment, but also may cause pollution to the surrounding environment. SUMMARY

[0004] The utility model aims at providing a steam-water mixing sound attenuation ejector to solve the problems of uneven mixing and loud noise of traditional steam-water mixing equipment.

[0005] To achieve the above-mentioned purpose, a steam-water mixing sound attenuation ejector is provided, which comprises a main channel, a gas inlet and a fluid inlet, the gas inlet is located at the front end of the main channel, the fluid inlet is located above the main channel, the connection between the main channel, the gas inlet and the fluid inlet is provided with a receiving chamber, the rear of the receiving chamber is provided with a flow collecting chamber, the rear of the flow collecting chamber is provided with a first mixing chamber, the rear of the first mixing chamber is provided with a flow dividing chamber, the rear of the flow dividing chamber is provided with a second mixing chamber, and the rear of the second mixing chamber is provided with an expansion chamber.

[0006] As a further improvement of the technical solution, a plurality of first mixing blades are rotatably connected in the first mixing chamber, and a plurality of second mixing blades are rotatably connected in the second mixing chamber.

[0007] As a further improvement of the technical solution, a plurality of first mixing blades are rotatably connected in the first mixing chamber, and a plurality of second mixing blades are rotatably connected in the second mixing chamber.

[0008] As a further improvement to this technical solution, a nozzle is fixedly connected to the rear of the gas inlet, the nozzle is disposed inside the receiving chamber, the gas inlet is fixedly connected to the main channel, and the fluid inlet is fixedly connected to the main channel.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this gas-water mixing silencer ejector, gas and fluid first enter from the gas inlet and fluid inlet respectively. After initial convergence in the receiving chamber, they sequentially pass through multiple chambers, including the collection chamber, the first mixing chamber, the diversion chamber, the second mixing chamber, and the expansion chamber, for mixing. This multi-chamber design provides ample mixing space, allowing the gas and water to fully contact each other. In addition, multiple sets of first mixing blades rotatably connected in the first mixing chamber and multiple sets of second mixing blades rotatably connected in the second mixing chamber further enhance the stirring and mixing effect. By continuously changing the flow direction, a complex flow path is formed, promoting molecular diffusion and energy exchange, thereby achieving efficient and uniform mixing.

[0011] 2. This gas-water mixing silencer ejector effectively reduces noise levels through a reasonable chamber layout and component arrangement. The collection chamber initially prepares the gas and fluid, making their flow more stable before entering subsequent chambers and reducing turbulence and impact in the initial stage. The first mixing blade in the first mixing chamber and the second mixing blade in the second mixing chamber continuously change the flow direction, forming a complex flow path, which not only promotes efficient mixing but also disperses noise sources and reduces the formation of local high-noise areas. The diversion chamber performs a diversion operation on the mixed fluid, making the fluid flow more stable and orderly, further reducing noise caused by turbulence and impact. The presence of the expansion chamber helps reduce noise. When the mixed fluid enters the expansion chamber, the flow velocity suddenly decreases and the pressure is released. According to the principles of fluid mechanics, this change in flow velocity and pressure can effectively reduce noise caused by pressure changes and fluid impact, making the entire device operate more quietly.

In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0020] Please refer to Figs. 1-3 As shown in the drawings, the present embodiment aims to provide a steam-water mixing and silencing ejector, which comprises a main channel 1, a gas inlet 2 and a fluid inlet 3. The gas inlet 2 is located at the front end of the main channel 1, and the fluid inlet 3 is located above the main channel 1. A receiving chamber 11 is arranged at the connection of the main channel 1, the gas inlet 2 and the fluid inlet 3, and a flow collecting chamber 12, a first mixing chamber 13, a flow dividing chamber 14, a second mixing chamber 15 and an expansion chamber 16 are arranged in sequence behind the receiving chamber 11. A nozzle 21 is fixedly connected behind the gas inlet 2, the nozzle 21 is arranged inside the receiving chamber 11, the gas inlet 2 is fixedly connected with the main channel 1, and the fluid inlet 3 is fixedly connected with the main channel 1. The design of the nozzle 21 enables the gas to enter the receiving chamber 11 at a high speed and pressure, so as to better mix with the fluid.

[0021] The receiving chamber 11 is where the gas and fluid first come together. In this chamber, the gas and fluid begin to make initial contact and mix, laying the foundation for the subsequent multi-chamber mixing process. The design of the receiving chamber 11 ensures the initial uniform distribution of the gas and fluid, reducing turbulence and impact in the initial stage, which is conducive to subsequent efficient mixing. The collecting chamber 12 is located behind the receiving chamber 11, and its main function is to preliminarily arrange the gas and fluid, making them flow more stably before entering the subsequent chamber. The design of the collecting chamber 12 reduces the turbulence and impact of the gas and fluid, providing good conditions for the subsequent mixing process.

[0022] The first mixing chamber 13 is located behind the collecting chamber 12, and a plurality of first mixing blades 131 are rotatably connected inside. These blades change the flow direction of the gas and fluid constantly, forming a complex flow path, promoting molecular diffusion and energy exchange, and thus achieving efficient mixing. The number and angle of the first mixing blades 131 are carefully designed to ensure optimal mixing results. Specifically, there are 10 groups of first mixing blades 131, and the inclination angle of each group of blades is 45 degrees. Such design has the following advantages: the arrangement of 10 groups of first mixing blades 131 can provide more stirring points, so that the gas and fluid can be more fully contacted and mixed in the first mixing chamber 13. Each blade stirs the fluid at different positions and angles, forming a complex flow path and enhancing the mixing effect. The 45-degree inclination angle design allows the blades to generate optimal shear force and vortex effect when the fluid passes through, and this angle can effectively change the flow direction of the fluid while avoiding excessive resistance to ensure smooth fluid flow. At the same time, the 45-degree angle also helps to disperse bubbles and reduce the aggregation of bubbles, further improving mixing uniformity.

[0023] The flow dividing chamber 14 is located behind the first mixing chamber 13, and its main function is to divide the mixed fluid, making the fluid flow more stable and orderly. The design of the flow dividing chamber 14 further reduces the noise caused by turbulence and impact, ensuring the stability of the mixing process. The second mixing chamber 15 is located behind the flow dividing chamber 14, and a plurality of second mixing blades 151 are rotatably connected inside. The design of these blades is different from that of the first mixing blades 131, and the inclination angle of the second mixing blades 151 is smaller than that of the first mixing blades 131, specifically 30 degrees, and the number of blades is more than that of the first mixing blades 131, specifically 15 groups. The design of the second mixing blades 151 further enhances the stirring and mixing effect, making the soda mixing more uniform through a more delicate flow path.

[0024] Specifically, the arrangement of 15 sets of second mixing blades 151 can provide more stirring points, so that the gas and the fluid can be more fully contacted and mixed in the second mixing chamber 15. The design of the 30-degree inclination angle enables the blades to generate a more gentle shear force and vortex effect when the fluid passes through, and this angle can effectively change the flow direction of the fluid and reduce excessive disturbance to the fluid, avoiding the generation of excessive turbulence and noise. At the same time, the 30-degree angle also helps to further disperse the bubbles, reduce the aggregation of the bubbles, and further improve the mixing uniformity.

[0025] The expansion chamber 16 is located behind the second mixing chamber 15, and its main function is to reduce the flow rate and pressure of the mixed fluid. When the mixed fluid enters the expansion chamber 16, the flow rate suddenly decreases and the pressure is released, according to the principle of fluid mechanics, this change of flow rate and pressure can effectively reduce the noise generated by the change of pressure and fluid impact, making the whole equipment run more quietly. Through reasonable chamber layout and component setting, the ejector effectively reduces the noise level.

[0026] Working principle: gas and fluid enter from gas inlet 2 and fluid inlet 3 respectively, gas enters the receiving chamber 11 at high speed through the nozzle 21 and preliminarily mixes with the fluid. The mixed gas and fluid enter the flow collecting chamber 12, which preliminarily arranges the gas and fluid to make the flow more stable. Then, the mixture flows into the first mixing chamber 13, and the 10 sets of first mixing blades 131 inside change the flow direction continuously, forming a complex flow path to promote molecular diffusion and energy exchange, achieving preliminary efficient mixing. Next, the mixture flows into the flow dividing chamber 14, which performs flow dividing operation on the mixed fluid to make the fluid flow more stable and orderly. Then, the mixture flows into the second mixing chamber 15, where the 15 sets of second mixing blades 151 continue to stir and mix, and the 30-degree inclination angle design further enhances the mixing effect, making the gas-liquid mixing more uniform. Finally, the mixed fluid enters the expansion chamber 16, the flow rate suddenly decreases, and the pressure is released, effectively reducing the noise. During the whole process, through the multi-chamber design and reasonable configuration of the mixing blades, efficient and uniform mixing effect is achieved, and the noise during equipment operation is significantly reduced.
