Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically a novel multi-layer nozzle. Background Technology

[0002] Traditional nozzles have certain limitations in terms of spray performance, adaptability, and ability to handle nozzle clogging. Therefore, developing a new type of nozzle to improve spray performance, reduce clogging, and enhance adaptability is of great significance. Utility Model Content

[0003] The present invention aims to provide an innovative multi-layer nozzle to effectively solve many problems existing in the current nozzle, improve the spraying effect, and expand the application range.

[0004] The technical solution adopted in this utility model is: a novel multi-layer nozzle, comprising a nozzle body, multiple channels, multiple flow channel layers, multiple nozzle nozzles, and a conical baffle located at the end of each flow channel layer. The nozzle body is made of high-strength, corrosion-resistant material to ensure stability and durability in various working environments. Flow is distributed through uniformly distributed channels, which can be adjusted according to different fluid properties and spraying requirements. A conical baffle is provided at the end of each flow channel layer; by changing its angle, the fluid spray direction and coverage area can be adjusted. The nozzle can be connected to a fluid delivery system via threaded connections, flange connections, etc., making installation convenient and quick.

[0005] The working principle of this invention is as follows: When fluid enters the nozzle, it is first diverted through uniformly distributed internal channels. A portion of the fluid enters the corresponding channel from the inlet of each channel layer. The cone at the end of each channel layer acts as a nozzle baffle, diverting and guiding the fluid, causing it to spray out in a specific direction and angle, forming a multi-layered spray effect. Under the action of their respective cone nozzle baffles, the fluid in multiple channel layers is sprayed out in different directions and angles, collectively forming a multi-layered spray effect. By adjusting the size and distribution of the diversion channels, the angle of the cone nozzle baffles, and parameters such as fluid pressure and flow rate, different spray ranges and spray intensities can be achieved to meet the needs of various application scenarios.

[0006] This utility model has the following beneficial effects:

[0007] 1. Improved spraying effect: The concentrated spraying of the inner nozzle and the diffused spraying of the outer nozzle work together to achieve a more uniform spray distribution and a finer atomization effect, thereby improving the coverage and uniformity of the spray.

[0008] 2. Easy installation and maintenance: The nozzle can be quickly installed on the cleaning equipment through threaded connection, flange connection and other methods. The installation and disassembly process is simple and quick, which reduces equipment downtime and improves production efficiency.

[0009] 3. Highly adaptable:

[0010] (1) The size of the gap between the multi-layer nozzles and the spray angle can be adjusted according to different needs;

[0011] (2) Applicable to various fluid media, such as cleaning fluid, coolant, water, etc.;

[0012] (3) It adapts to various complex working scenarios, such as chemical impurity removal, environmental dust removal, industrial cooling, fire extinguishing, and agricultural irrigation, and has unique application advantages.

[0013] 4. Reduce clogging and scaling: A well-designed multi-layer nozzle can produce finer droplets, reducing droplet aggregation and deposition, lowering the risk of clogging and scaling inside the nozzle and pipe, and reducing the frequency of maintenance and cleaning.

[0014] 5. Reduce energy consumption:

[0015] (1) The optimized nozzle structure reduces fluid resistance and reduces the energy required for fluid delivery;

[0016] (2) Multi-layer spraying can achieve good cleaning effect at lower fluid pressure, further reducing energy consumption.

[0017] In summary, this invention demonstrates significant innovation and advantages in the field of nozzle technology, excelling in improving spraying efficiency, reducing energy consumption, and offering wide applicability. With the increasing demands for cleaning technology in industrial production, this novel double-layer nozzle has broad application prospects and market potential. Attached Figure Description

[0023] To further understand this utility model, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide further details. It should be noted that the arrows in the drawings indicate the direction of water flow.

[0024] First, the operation of the embodiment will be explained using a double-layer nozzle as an example: Figure 1 As shown, when water enters the nozzle, it enters the double-layer flow channel through eight evenly distributed 5mm diameter orifices inside the nozzle. The angle between the nozzle orifice and the vertical plane is 65° to 85°, thus forming a 20° spray angle. The nozzle outer diameter is set to 38mm, the inner diameter of the first flow channel is 20mm, and the inner diameter of the second flow channel is 30mm. The annular gap of both the first and second flow channels is 0.6mm. Using the cross-sectional area of ​​the first annular gap as a comparison benchmark, the ratio of the cross-sectional area of ​​the second annular gap to that of the first annular gap is calculated to be 1.51, and the cross-sectional area ratio of the eight 5mm diameter transverse orifices is 4.3. The water flow rate of each nozzle is 5m³. 3 The bottom layer carries approximately 40% of the water per hour. Calculations show that the linear velocity of the inlet pipe is 2 m / s, the linear velocity of the first layer is 15.1 m / s, and the linear velocity of the second layer is 15.1 m / s.

[0025] The first layer of this invention has a linear velocity of 15.1 m / s. This high linear velocity creates a strong impact and mixing effect in the first layer, promoting rapid contact between the raw coal gas and the washing water. The second layer also has a linear velocity of 15.1 m / s, consistent with the first layer, ensuring the stability of the washing effect of the entire nozzle in the vertical direction.

[0026] The operation of the embodiment is explained below using a three-layer nozzle as an example: Figure 2 As shown, when water enters the nozzle, it flows through six evenly distributed 3.2mm diameter channels inside the nozzle into a three-layer flow channel. The angle between the nozzle orifice and the vertical plane is 65° to 85°, thus forming a 20° spray angle. The nozzle outer diameter is set to 25mm, the inner diameter of the first flow channel is 10mm, the second flow channel is 15mm, and the third flow channel is 20mm. The annular gap of each of the three flow channels is 0.4mm. Calculations are performed using the cross-sectional area of ​​the first annular gap as a benchmark. The ratio of the cross-sectional area of ​​the second annular gap to that of the first is approximately 1.52, and the ratio of the cross-sectional area of ​​the third annular gap to that of the first is approximately 2.04. The cross-sectional area ratio of the six 3.2mm diameter transverse holes is 2.5. The water flow rate of each nozzle is 1m³. 3 / h. The bottom first layer carries approximately 22% of the water. Calculations show that the linear velocity of the inlet pipe is 0.9 m / s, the linear velocity of the first layer is approximately 5 m / s, the linear velocity of the second layer is approximately 7.6 m / s, and the linear velocity of the third layer is approximately 10.2 m / s.

[0027] The multi-layered structure causes the fluid to undergo multiple breaks and mixtures during ejection, resulting in finer droplets and enhanced atomization. Good atomization helps increase the surface area of ​​the fluid, promoting the transfer, mixing, and reaction of substances.

[0028] Through the above specific embodiments, this utility model can achieve efficient and uniform rinsing, reducing the risk of nozzle clogging and energy consumption while ensuring the cleaning effect.
