Description

Technical Field

[0001] This application relates to the technical field of high-efficiency atomizing denitrification spray guns, and in particular to a high-efficiency atomizing denitrification spray gun. Background Technology

[0002] In industrial production and environmental protection, especially for the treatment of waste gases generated from combustion, denitrification technology is an important environmental protection measure aimed at reducing the emission of nitrogen oxides (NOx) to mitigate their harm to the environment and meet increasingly stringent environmental regulations.

[0003] Traditional denitrification processes often employ denitrification spray guns with several shortcomings. Generally, traditional denitrification spray guns suffer from poor atomization, failing to sufficiently refine the denitrifying agent into tiny droplets. This results in a small contact area between the denitrifying agent and nitrogen oxides in the exhaust gas, thus affecting the efficiency of the denitrification reaction. For example, some spray guns may use simple single-fluid nozzles, relying solely on liquid pressure to propel the denitrifying agent. This leads to larger droplets that are difficult to mix thoroughly with the exhaust gas in a short time, affecting the uniformity and thoroughness of the denitrification reaction and resulting in insignificant denitrification effects, failing to achieve the desired nitrogen oxide emission reduction targets. Those skilled in the art have developed a high-efficiency atomizing denitrification spray gun to address the problems mentioned in the background section. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a high-efficiency atomizing denitrification spray gun.

[0005] The high-efficiency atomizing denitrification spray gun provided in this application adopts the following technical solution:

[0006] A high-efficiency atomizing denitrification spray gun includes a spray pipe, a flange fixedly installed on the outside of the spray pipe, a positioning bolt passing through the outside of the flange, a steam connection pipe connected to one end of the spray pipe, and an ammonia connection pipe connected to the lower end of the steam connection pipe, and a nozzle provided at the other end of the spray pipe.

[0007] Preferably, a sealing gasket is fixedly installed on the outside of the nozzle, the nozzle is threadedly connected to one end of the spray pipe, and the sealing gasket abuts against the outside of the spray pipe.

[0008] Preferably, the nozzle is made of stainless steel, with a round hole on one side and a spray hole on the other side.

[0009] Preferably, the nozzle has an atomizer inside, and three guide rods are fixedly installed on the outside of the atomizer.

[0010] Preferably, the three guide rods are arranged at an angle, and a locking block is fixedly installed at one end of each guide rod.

[0011] Preferably, a circular groove is provided on one side of the inner wall of the nozzle, outside the circular hole, and the locking block is movably engaged with the circular groove.

[0012] In summary, this application includes the following beneficial technical effects: by providing an atomizer inside the front nozzle, and a guide rod fixedly connected to the outer surface of the atomizer, with one end of the guide rod movably connected to one side of the inner wall of the front nozzle, the reducing agent will quickly disperse and atomize when it comes into contact with the atomizer in the form of a water column. After the atomizer is impacted by the reducing agent, the guide rod rotates, thereby causing the spray droplets to enter the boiler furnace in a rotating manner. This avoids the safety accident of boiler water-cooled wall tube penetration or rupture caused by the water column directly spraying onto the opposite furnace, which would cause a sharp drop in the surface temperature of the water-cooled wall. It is safe and practical. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-3 As shown, a high-efficiency atomizing denitrification spray gun includes a spray pipe 1, a flange 3 fixedly installed on the outside of the spray pipe 1, a positioning bolt 4 passing through the outside of the flange 3, a steam connection pipe 5 connected to one end of the spray pipe 1, and an ammonia connection pipe 6 connected to the lower end of the steam connection pipe 5, and a nozzle 2 provided at the other end of the spray pipe 1.

[0019] By installing an atomizer 8 inside the front nozzle 2, and a guide rod 9 fixedly connected to the outer surface of the atomizer 8, one end of the guide rod 9 is movably connected to one side of the inner wall of the front nozzle 2. When the reducing agent comes into contact with the atomizer 8 in the form of a water column, it will quickly disperse and atomize. After the atomizer 8 is impacted by the reducing agent, the guide rod 9 rotates, so that the spray droplets enter the boiler furnace in a rotating manner. This avoids the safety accident of the boiler water-cooled wall tube penetration or burst caused by the water column directly spraying onto the opposite furnace, which would cause a sharp drop in the surface temperature of the water-cooled wall. It is safe and practical.

[0020] In this embodiment, a sealing gasket 7 is fixedly installed on the outside of the nozzle 2. The nozzle 2 is threadedly connected to one end of the nozzle pipe 1, and the sealing gasket 7 abuts against the outside of the nozzle pipe 1.

[0021] In this embodiment, the nozzle 2 is made of stainless steel, and a round hole 10 is provided on one side of the nozzle 2, while a spray hole is provided on the other side of the nozzle 2.

[0022] In this embodiment, an atomizer 8 is provided inside the nozzle 2, and three guide rods 9 are fixedly installed on the outside of the atomizer 8.

[0023] In this embodiment, the three guide rods 9 are arranged at an angle, and a locking block 12 is fixedly installed at one end of each guide rod 9.

[0024] In this embodiment, a circular groove 11 is provided on one side of the inner wall of the nozzle 2, located outside the circular hole 10, and the locking block 12 is movably engaged with the circular groove 11.

[0025] The implementation principle of the high-efficiency atomizing denitrification spray gun in this application embodiment is as follows: an atomizer 8 is set inside the front nozzle 2, and a guide rod 9 is fixedly connected to the outer surface of the atomizer 8. One end of the guide rod 9 is movably connected to one side of the inner wall of the front nozzle 2. When the reducing agent comes into contact with the atomizer 8 in the form of a water column, it will quickly disperse and atomize. After the atomizer 8 is impacted by the reducing agent, the guide rod 9 rotates, so that the spray droplets enter the boiler furnace in a rotating form. This avoids the safety accident of the boiler water-cooled wall tube penetration or burst caused by the water column directly spraying onto the opposite furnace, which would cause a sharp drop in the surface temperature of the water-cooled wall. It is safe and practical.
