Description

Technical Field

[0001] This utility model relates to the field of atomizing nozzle technology, and in particular to an ultrasonic atomizing nozzle. Background Technology

[0002] With the acceleration of industrialization, the amount of waste gas and waste liquid generated is constantly increasing, causing many negative impacts on the environment and seriously threatening the ecological balance and sustainable development of mankind. Industrial waste liquid often contains heavy metals (such as mercury, cadmium, lead, chromium, etc.), organic pollutants (such as phenols, cyanides, polycyclic aromatic hydrocarbons, etc.), acid and alkali substances, as well as a large amount of chemical oxygen demand (COD) and biochemical oxygen demand (BOD). The discharge of waste gas and waste liquid has caused serious damage to the entire ecosystem. In order to treat industrial waste liquid, it is usually atomized and then incinerated to remove harmful pollutants from the waste liquid. In the process of treating waste gas and waste liquid, the nozzle is a key component, and its performance directly affects the treatment effect.

[0003] The commonly used nozzles in existing technologies are internal mixing nozzles. These nozzles use an oil pump to apply high pressure to liquid fuel, forcing it to be ejected through a small orifice. The pressure difference and high-speed airflow then disperse the liquid fuel into a mist. However, internal mixing nozzles require high-pressure oil pumps, increasing equipment costs and energy consumption. Unstable pump pressure leads to fluctuations in atomization, affecting combustion stability. Over time, impurities in the fuel can clog the nozzle orifices, necessitating regular cleaning and maintenance; otherwise, atomization quality will decrease, potentially damaging the nozzle. Furthermore, internal mixing nozzles consume large amounts of compressed air, increasing operating costs. Moisture or impurities in the compressed air can also affect atomization. Therefore, existing nozzle technologies cannot meet the demands of environmental protection equipment for efficient, stable, and low-cost atomization. A new type of atomizing nozzle is urgently needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic atomizing nozzle, which has the advantages of simple structure and good atomization effect.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an ultrasonic atomizing nozzle, comprising:

[0006] The main body base is used to connect the ultrasonic generator and the atomizing head;

[0007] The adjusting ring, connected to the main body base, is used to receive the energy transmitted from the main body base, causing the atomizing medium to vibrate at high frequency.

[0008] The nozzle, located at the end of the liquid spray, has its outlet opposite the area where the regulating ring generates high-frequency vibration. It is used to spray out liquid, so that the liquid and the high-frequency vibration generated by the regulating ring converge, breaking the liquid into tiny droplets. It is also indirectly connected to the waste liquid rod through the main body base.

[0009] The present invention is further configured such that: the ultrasonic atomizing nozzle generates ultrasonic waves based on the flow characteristics of air under supercritical pressure to achieve liquid atomization; the air is ejected at a supercritical pressure ratio to form a periodic density fluctuation jet to cause the air to relax and oscillate, and the oscillation is within the ultrasonic range, thereby generating ultrasonic waves for liquid atomization.

[0010] The present invention is further configured such that: the ultrasonic atomizing nozzle is equipped with a Hartmann ultrasonic generator, the opening of which is annular and opposite to the circular gas outlet; the gas for atomization is ejected at high speed from the circular gas outlet, generating strong turbulence to initially atomize the liquid, while the ultrasonic waves generated by the Hartmann ultrasonic generator act on the initially atomized droplets, causing the droplets to oscillate at high frequency and further break up.

[0011] The present invention is further configured such that the connection between the main body base and the ultrasonic generator and the atomizing head is a detachable connection, and the connection structure is one of threaded connection, snap-fit ​​or plug-in connection.

[0012] The present invention is further configured such that the adjusting ring is made of 310S or Hastelloy.

[0013] The present invention is further configured such that: the ultrasonic atomizing nozzle also includes a sealing structure disposed between the body base, the adjusting ring and the nozzle, wherein the sealing structure is one of a rubber sealing ring, a sealant or a metal sealing gasket.

[0014] The present invention is further configured such that: the ultrasonic atomizing nozzle also includes a flow regulating device, which is disposed at the liquid inlet of the nozzle and is used to regulate the liquid flow without affecting the uniformity of the atomized particles.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. Ultrasonic atomizing nozzles achieve liquid atomization based on ultrasonic waves generated by air flow under supercritical pressure. They combine a dual mechanism of turbulent pre-atomization generated by high-speed gas jet and ultrasonic secondary atomization. This dual atomization mechanism enables the liquid to be broken into finer droplets, greatly improving atomization efficiency and quality. Compared with traditional atomization methods, it can perform more efficient atomization of low-viscosity liquids. Even if the liquid contains sediments, it can achieve atomization of the entire liquid jet. It can even atomize multiple liquids simultaneously in the same nozzle to meet diverse industrial needs.

[0017] 2. The main body base, ultrasonic generator, and atomizing head are detachably connected, facilitating installation, disassembly, and maintenance. The adjusting ring is made of 310S or Hastelloy alloy, possessing high strength, high hardness, and excellent wear and corrosion resistance, ensuring long-term stable operation in high-frequency vibration environments and extending the equipment's service life. Simultaneously, a sealing structure, such as a rubber sealing ring, sealant, or metal gasket, is installed between the main body base, adjusting ring, and nozzle to effectively prevent liquid and gas leakage, ensuring the stability and safety of equipment operation. The nozzle is equipped with a flow regulating device located at the liquid inlet, ensuring that adjusting the liquid flow does not affect the uniformity of the atomized particles. This allows for precise control of the liquid output according to actual production needs, achieving more accurate atomization operation and improving the controllability of the production process and product quality.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example:

[0022] refer to Figure 1 An ultrasonic atomizing nozzle, comprising:

[0023] The main body base 1 is used to connect the ultrasonic generator and the atomizing head;

[0024] The adjusting ring 2 is connected to the main body base 1 and is used to receive the energy transmitted by the main body base 1 to make the atomizing medium vibrate at high frequency. The adjusting ring 2 is made of 310S or Hastelloy, and can also be made of other metal materials with high strength and corrosion resistance.

[0025] Nozzle 3 is located at the end of the liquid spraying position. Its outlet is opposite to the area where the regulating ring 2 generates high-frequency vibration. It is used to spray liquid so that the liquid and the high-frequency vibration generated by the regulating ring 2 converge, breaking the liquid into tiny droplets. It is also indirectly connected to the waste liquid rod through the main body base 1.

[0026] Specifically, the ultrasonic atomizing nozzle generates ultrasonic waves based on the flow characteristics of air under supercritical pressure to achieve liquid atomization. Air is ejected at a supercritical pressure ratio to form a periodic density fluctuation jet, causing the air to relax and oscillate. This oscillation is within the ultrasonic range, and the ultrasonic waves generated are used for liquid atomization. The ultrasonic atomizing nozzle is equipped with a Hartmann ultrasonic generator, whose opening is annular and opposite to a circular gas outlet. The gas used for atomization is ejected at high speed from the circular gas outlet, generating strong turbulence to initially atomize the liquid. At the same time, the ultrasonic waves generated by the Hartmann ultrasonic generator act on the initially atomized droplets, causing the droplets to oscillate at high frequency and further break them up.

[0027] Specifically, the connection between the main body base 1 and the ultrasonic generator and atomizing head is a detachable connection, and the connection structure is one of threaded connection, snap-fit ​​or plug-in connection, preferably a threaded connection.

[0028] Specifically, the ultrasonic atomizing nozzle also includes a sealing structure disposed between the body base 1, the adjusting ring 2 and the nozzle 3. The sealing structure is one of a rubber sealing ring, a sealant or a metal sealing gasket, preferably a rubber sealing ring.

[0029] Specifically, the ultrasonic atomizing nozzle also includes a flow regulating device, which is located at the liquid inlet of the nozzle 3 to regulate the liquid flow rate without affecting the uniformity of the atomized particles.

[0030] Brief description of operation: The energy generated by the ultrasonic generator is transmitted to the regulating ring 2 through the base 1, causing the atomizing medium within the regulating ring 2 to vibrate at high frequency. Simultaneously, supercritical pressure air is ejected from a specific channel according to a set pressure ratio, forming a periodic density fluctuation jet that induces relaxation oscillations to generate ultrasonic waves. The gas used for atomization is ejected at high speed from the circular gas outlet of the Hartmann ultrasonic generator, generating strong turbulence to initially atomize the liquid ejected from the nozzle 3. The initially atomized droplets are further broken into tiny droplets by the high-frequency oscillations generated by the Hartmann ultrasonic generator, achieving highly efficient atomization.

After reading this specification, those skilled in the art can make modifications to this embodiment that make creative contributions as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
