Description

Technical Field

[0001] This utility model belongs to the field of atomizing nozzle technology, and in particular relates to a steam-assisted atomizing nozzle. Background Technology

[0002] In industrial production, steam desuperheaters are widely used. The desuperheating water nozzle is a key component of the desuperheater. The function of the nozzle is to atomize the desuperheating water and exchange heat with the steam coming from upstream, turning it into superheated steam at a lower temperature. If the desuperheating water is not atomized well, it will greatly affect the performance of the desuperheater. Optimizing the performance of the nozzle is a perpetual need for the product.

[0003] When the pressure difference between steam and desuperheating water is small, existing steam-assisted atomizing nozzles cannot atomize steam and desuperheating water simultaneously in the same nozzle; therefore, this invention proposes a steam-assisted atomizing nozzle to solve the above problem. Utility Model Content

[0004] This invention provides a steam-assisted atomizing nozzle, which aims to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a steam-assisted atomizing nozzle, including a nozzle body;

[0006] The nozzle body is equipped with a steam pipe and a water pipe that are parallel to each other. The steam pipe is connected to the nozzle, the nozzle is connected to the water pipe, the water pipe is connected to an elbow, and the end face of the elbow is provided with a flange.

[0007] Preferably, the nozzle is connected to an external cooling water pipe via a pipeline.

[0008] Preferably, the nozzle body has multiple threaded holes, which are distributed in a circular pattern.

[0009] Preferably, the steam pipe is connected to a high-pressure, high-temperature steam pipeline.

[0010] Preferably, the flange is fixedly connected to the elbow.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When the pressure difference between steam and desuperheating water is relatively small, the high-pressure, high-temperature steam pipeline is connected to the steam pipe. A fixing bolt is used to engage with multiple threaded holes arranged in a ring on the nozzle body to secure the connection. Then, the desuperheating water pipe is connected to the upper end of the nozzle. High-temperature, high-pressure steam enters the nozzle through the steam pipe, and simultaneously, the desuperheating water switch is opened, allowing the desuperheating water to enter the nozzle as well. The steam and desuperheating water are then desuperheated and atomized within the atomizing core of the nozzle. The atomized high-pressure steam then pushes the spring on the nozzle to extend, thereby depressurizing the atomized steam and discharging it from the nozzle into the water pipe. The desuperheated and depressurized steam is then discharged through an elbow and flange. This steam-assisted atomizing nozzle, when the pressure difference between steam and desuperheating water is relatively small, utilizes a small portion of steam to directly atomize the desuperheating water within the same nozzle to obtain desuperheated and depressurized steam.

[0023] Please see Figures 1 to 3 This utility model provides a technical solution: a steam-assisted atomizing nozzle, including a nozzle body 1; the nozzle body 1 is provided with a steam pipe 2 and a water pipe 3 that are parallel to each other, the steam pipe 2 is connected to a nozzle 4, the nozzle 4 is connected to the water pipe 3, the water pipe 3 is connected to an elbow 5, and the end face of the elbow 5 is provided with a flange 6.

[0024] Furthermore, nozzle 4 is connected to an external cooling water pipe via a pipeline.

[0025] For further details, please refer to Figure 1 and Figure 3 The nozzle body 1 has multiple threaded holes, which are distributed in a circular pattern.

[0026] Furthermore, steam pipe 2 is connected to a high-pressure, high-temperature steam pipe.

[0027] For further details, please refer to Figure 1 Flange 6 is fixedly connected to elbow 5.

[0028] In this embodiment, the steam-assisted atomizing nozzle is suitable for use when the pressure difference between steam and desuperheating water is relatively small. A high-pressure, high-temperature steam pipe is connected to the steam pipe 2, and a fixing bolt is used to engage with multiple threaded holes arranged in a ring on the nozzle body 1 to achieve a fixed connection between the high-pressure, high-temperature steam pipe and the steam pipe 2. Then, the desuperheating water pipe is connected to the upper end of the nozzle 4. When the pressure difference between steam and desuperheating water is relatively small, high-temperature, high-pressure steam enters the nozzle 4 through the steam pipe 2. Simultaneously, the desuperheating water switch is opened, and desuperheating water also enters the nozzle 4. The steam and desuperheating water are then desuperheated and atomized within the atomizing core of the nozzle 4. The atomized high-pressure steam then pushes the spring on the nozzle 4 to extend, thereby depressurizing the atomized steam and discharging it from the nozzle 4 into the water pipe 3. The desuperheated and depressurized steam is then discharged through the elbow 5 and flange 6. This steam-assisted atomizing nozzle, when the pressure difference between steam and desuperheating water is relatively small, utilizes a small portion of steam to directly atomize the desuperheating water in the same nozzle 4 to obtain desuperheated and depressurized steam.

[0029] The working principle and usage process of this utility model are as follows: When the pressure difference between steam and desuperheating water is relatively small, the high-pressure high-temperature steam pipe is connected to the steam pipe 2. The fixing bolts are used to engage with multiple threaded holes arranged in a ring on the nozzle body 1 to achieve a fixed connection between the high-pressure high-temperature steam pipe and the steam pipe 2. Then, the desuperheating water pipe is connected to the upper end of the nozzle 4. High-temperature and high-pressure steam enters the nozzle 4 through the steam pipe 2. At the same time, the desuperheating water switch is turned on, and the desuperheating water also enters the nozzle 4. Then, the steam and desuperheating water are desuperheated and atomized in the atomizing core in the nozzle 4. The atomized high-pressure steam will push the spring on the nozzle 4 to extend, thereby depressurizing the atomized steam and discharging it from the nozzle 4 into the water pipe 3. Then, it is discharged through the elbow 5 and flange 6. The desuperheated and depressurized steam is discharged through the elbow 5 and flange 6. This steam-assisted atomizing nozzle uses a small portion of steam to directly atomize the desuperheating water in the same nozzle 4 to obtain desuperheated and depressurized steam when the pressure difference between steam and desuperheating water is relatively small.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
