Description

Technical Field

[0001] This utility model relates to the field of industrial equipment technology, and in particular to a spray gun device with a protective sleeve for high-salt wastewater return spraying. Background Technology

[0002] Quenching towers are widely used in industrial flue gas treatment fields such as chemical industry, medical waste, and waste incineration. Quenching towers spray quenching water through spray guns to rapidly cool high-temperature flue gas (600-1500℃) to below 200℃, thereby effectively inhibiting the resynthesis of harmful substances such as dioxins and achieving the initial removal of acidic gases and particulate matter.

[0003] In existing technologies, the spray gun devices in quench towers typically lack protective sleeves. When using high-salt industrial wastewater as quench water, these conventional spray guns without protective sleeves are highly susceptible to corrosion from flue gas at the spray gun pipe interface and spray gun head, resulting in unsatisfactory spray gun performance. Additionally, some existing technologies include spray guns with protective sleeves, such as the spray gun structure for quench towers disclosed in patent document CN221173104U. However, these spray guns with protective sleeves suffer from drawbacks such as inconvenient installation and difficulty in removing the protective sleeve. Furthermore, the spray head remains exposed, making it prone to corrosion. Utility Model Content

[0004] In order to solve the above problems, the present invention aims to provide a spray gun device with a protective sleeve that is easy to remove and does not easily corrode high-salt wastewater and can be used for back spraying.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a spray gun device with a protective sleeve for high-salt wastewater return spraying. The device comprises: a spray gun body and a protective sleeve. The spray gun body has a tubular structure. A nozzle is provided at the front end of the spray gun body. The nozzle includes an elbow connected to the tubular structure and a spray head connected to the elbow. A compressed air inlet and a quench water inlet are connected to the rear end of the tubular structure. The protective sleeve is fitted around the outer periphery of the spray gun body, and the nozzle is located inside the protective sleeve. Through holes corresponding to the spray head are opened on the circumferential surface of the protective sleeve. Two supports are fixedly connected to the outer wall of the tubular structure. The two supports are located at the front end and middle of the tubular structure, respectively, and both supports are located inside the protective sleeve. The supports are provided with spherical fulcrums.

[0007] Furthermore, the spray gun device with protective sleeve for high-salt wastewater return spray provided by this utility model may also have the following features: the support has a figure-eight symmetrical structure, and each support includes two rods welded to the outer wall of the tubular structure and two spherical fulcrums welded to the ends of the two rods respectively.

[0019] See Figure 1 This embodiment provides a spray gun device with a protective sleeve for high-salinity wastewater return spraying, including a spray gun body and a protective sleeve 12. Both the spray gun body and the protective sleeve 12 are made of stainless steel.

[0020] The spray gun body has a tubular structure 1, and a nozzle is provided at the front end of the spray gun body. The nozzle consists of an elbow 9 and a spray head 10. The elbow 9 is a right-angle elbow, and the elbow 9 is connected to the tubular structure 1 through a conventional pipe connection method. The spray head 10 is connected to the end of the elbow 9. A protective sleeve 12 is fitted around the outer periphery of the spray gun body, and the nozzle is located inside the protective sleeve 12. A through hole corresponding to the spray head 10 is opened on the circumference of the protective sleeve 12. In actual use, the area of ​​the through hole is slightly larger than the spray surface of the spray head 10, so that the spray surface of the spray head 10 is exposed, while the rest of the spray head 10 is not exposed.

[0021] The rear end of the tubular structure 1 is connected to a compressed air inlet 3 and a quench water inlet 6, forming an integrated structure. The compressed air inlet 3 is used to connect to external compressed air equipment to supply compressed air. The compressed air inlet 3 is equipped with a one-way valve 4 to restrict the airflow direction, and a quick connector 5 at the end of the inlet facilitates quick connection and disconnection with the external compressed air equipment's pipeline. The quench water inlet 6 is used to connect to a high-salt wastewater conveying pipeline. The quench water inlet 6 is also equipped with a one-way valve 7, and a quick connector 8 at the end of the inlet.

[0022] Two supports 7 are fixed to the outer wall of the tubular structure 1. The two supports 7 are located at the front end and middle of the tubular structure 1, respectively, and both supports 7 are located inside the protective sleeve 12. See also Figure 2 The bracket 7 has a symmetrical V-shaped structure. Each bracket 7 includes two rods 71 ​​and two spherical fulcrums 72. The two rods 71 ​​are welded to the outer wall of the tubular structure 1, and spherical fulcrums 72 are welded to the ends of the two rods 71. During the installation and removal of the spray gun and the protective sleeve, the spherical fulcrums inevitably come into contact with the protective sleeve. By using such spherical fulcrums for contact, friction during contact with the protective sleeve can be reduced, allowing for smooth installation and removal of the protective sleeve.

[0023] A spray gun flange 2 is located in the middle of the tubular structure 1, and a ring of first bolt holes (not shown in the figure) is formed on the spray gun flange 2. One end face of the protective sleeve 12 ( Figure 1 The right end face is a closed structure, while the other end face is open. A sleeve flange 11 is installed at this opening, and a ring of second bolt holes (not shown in the figure) corresponding to the first bolt holes are formed on the sleeve flange 11. The sleeve flange 11 is bolted to the spray gun flange 2, and sealing gaskets or washers can be installed at both flanges as needed. The number and position of the first and second bolt holes can be arranged according to the actual situation of the spray gun device. For example, a larger cooling tower will use a larger spray gun device, and the corresponding dimensions of the spray gun flange 2 and sleeve flange 11 will also be larger. In this case, a larger number of bolts can be used to connect the two.

[0024] A protective air inlet 13 is welded to the circumference of the protective sleeve 12. The protective air inlet 13 is used to protect the gas from entering, and the protective gas plays a role in air cooling protection. The protective air inlet 13 is also equipped with a one-way valve 14 to direct the airflow direction, and the end of the protective air inlet 13 is also equipped with a quick connector 15 for quick connection and disconnection with the pipeline.

[0025] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
