Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of chemical production, specifically to a hydrogen mother liquor atomizing spray gun. Background Technology
[0002] Our company specializes in the research, development, production, and sales of sulfuric acid. Our process uses liquid sulfur as raw material, which is burned to produce SO2. The generated SO2 is then converted into SO3 in the presence of a catalyst. The SO3 is absorbed by concentrated sulfuric acid in an absorption tower to obtain a higher concentration of sulfuric acid, which is then mixed with demineralized water to obtain qualified sulfuric acid. In this process, a hydrogen mother liquor (organic waste liquid generated during the sedimentation and stratification process of the ammonium sulfate production line) is sprayed into the SO3 through an atomizing spray gun to increase the temperature and retard the flame of the SO3.
[0003] When spraying hydrogen mother liquor, the atomizing spray gun uses pressurized gas as an auxiliary power source for hydrogen mother liquor atomization. By mixing the pressurized gas and hydrogen mother liquor, they collide and impact each other, thus dispersing and atomizing the hydrogen mother liquor before it is sprayed from the nozzle. In existing technology, when mixing pressurized gas and hydrogen mother liquor, the atomizing spray gun introduces both into the same chamber. The pressure of the pressurized gas mixes the hydrogen mother liquor, but because the pressurized gas is blown out at a relatively high speed, the contact time with the hydrogen mother liquor is relatively short. This results in the pressurized gas and hydrogen mother liquor not being fully mixed before being sprayed directly from the nozzle. The insufficient impact and collision between the two leads to poor atomization of the hydrogen mother liquor, thus affecting its temperature-enhancing and flame-retardant effect on SO3. Utility Model Content
[0004] The present invention aims to provide a hydrogen mother liquor atomizing spray gun that can improve the atomization effect of hydrogen mother liquor, thereby improving the heating and flame-retardant effect of hydrogen mother liquor on SO3.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] 1) A hydrogen mother liquor atomizing spray gun, comprising a chamber, an inlet pipe for supplying hydrogen mother liquor into the chamber is provided at one end of the chamber, an air inlet for supplying pressurized gas into the chamber is provided on the side of the chamber near the inlet pipe, a nozzle for supplying atomized hydrogen mother liquor is sleeved at the other end of the chamber, a fixing block is provided inside the chamber, the fixing block is located between the nozzle and the inlet pipe, a feeding chamber is formed between the side of the fixing block facing the inlet pipe and the air inlet and the inner wall of the chamber, an atomizing chamber is formed between the side of the fixing block facing the nozzle and the inner wall of the chamber, a through hole is provided on the side of the fixing block to connect the atomizing chamber and the feeding chamber, and an atomizing structure is provided in the atomizing chamber to promote contact and mixing of pressurized gas and hydrogen mother liquor.
[0007] In this invention, since the side of the fixed block facing the air inlet and liquid inlet pipe forms a feeding chamber with the inner wall of the chamber, when pressurized gas and hydrogen mother liquor are introduced into the chamber through the air inlet and liquid inlet pipe respectively, the pressurized gas and hydrogen mother liquor enter the feeding chamber, then pass through the through hole into the atomization chamber, move towards the nozzle, and are sprayed out from the nozzle.
[0008] During the process of pressurized gas and hydrogen mother liquor entering the feed chamber, the pressurized gas and hydrogen mother liquor are initially mixed, causing the hydrogen mother liquor to collide and disperse, thus completing the first atomization of the hydrogen mother liquor. As the pressurized gas and hydrogen mother liquor pass through the through-hole, they are compressed, further promoting contact and mixing, completing the second atomization. As the pressurized gas and hydrogen mother liquor move towards the nozzle, they pass through the atomization structure in the atomization chamber. This atomization structure further promotes contact and mixing between the hydrogen mother liquor and pressurized gas, completing the third atomization. This three-stage atomization of the hydrogen mother liquor enhances its atomization effect, thereby improving its temperature-enhancing and flame-retardant effect on SO3.
[0009] 2) A hydrogen mother liquor atomizing spray gun according to 1), wherein:
[0010] The end of the inlet pipe located within the feed chamber is connected to a nozzle for spraying out hydrogen mother liquor. In this invention, when hydrogen mother liquor is introduced into the feed chamber, the hydrogen mother liquor is sprayed into the through hole through the nozzle along the inlet pipe. At this time, the hydrogen mother liquor is dispersed into larger droplets by the nozzle, which can make more sufficient contact with the pressurized gas in the feed chamber, thereby improving the effect of initial mixing and atomization of hydrogen mother liquor and pressurized gas.
[0011] 3) A hydrogen mother liquor atomizing spray gun according to 1), wherein:
[0012] The atomizing structure includes a main rod located within the atomizing chamber and extending axially therein. A rotating rod is connected to the end of the main rod facing the nozzle. The axis of the rotating rod is perpendicular to the axis of the main rod. Slider blocks are connected to both ends of the rotating rod. An annular groove is provided on the inner sidewall of the chamber for the slider to move circumferentially along the chamber. The slider is embedded in the annular groove. A rotating component that can drive the main rod to rotate is connected to the end of the main rod facing the through hole. Three atomizing discs are provided on the main rod to facilitate contact and mixing of pressurized gas and hydrogen mother liquor. The three atomizing discs are evenly arranged along the axial direction of the main rod and located between the rotating component and the rotating rod.
[0013] In this invention, pressurized gas and hydrogen mother liquor enter the atomizing chamber through the through hole and move towards the nozzle. During this process, the rotating component can drive the main rod to rotate. As the main rod rotates, it drives the atomizing disc to rotate and simultaneously drives the rotating rod to rotate. During the rotation of the rotating rod, the rotating rod drives the slider to move circumferentially within the annular groove of the chamber.
[0014] As the rotating rod drives the slider to move circumferentially within the annular groove, the cooperation between the slider and the annular groove ensures the stability of the rotating rod, main rod, rotating component, and atomizing disc during rotation. During the rotation of the rotating component, atomizing disc, and rotating rod, they agitate the hydrogen mother liquor and pressurized gas, promoting mixing and causing them to collide and disperse, thus atomizing the hydrogen mother liquor. As the hydrogen mother liquor and pressurized gas pass through the atomizing disc, the disc further promotes mixing, enhancing the atomization effect of the hydrogen mother liquor.
[0015] 4) A hydrogen mother liquor atomizing spray gun according to 3), wherein:
[0016] The rotating component includes a rotating shaft, one end of which is connected to the end of the main rod facing the through hole, and the other end of which extends toward the through hole. Several turbine blades are arranged radially on the side of the rotating shaft, and the turbine blades are evenly arranged circumferentially along the rotating shaft.
[0017] In this invention, when the pressurized gas and hydrogen mother liquor enter the atomization chamber through the through hole, they come into contact with the turbine blades, driving the turbine blades to rotate. During the rotation of the turbine blades, the turbine blades drive the rotating shaft to rotate, which in turn drives the main rod connected to it to rotate. During the rotation of the main rod, the main rod drives the atomizing disk and rotating rod connected to it to rotate. During the rotation of the turbine blades, atomizing disk, and rotating rod, the hydrogen mother liquor and pressurized gas can be agitated, promoting the mixing of the hydrogen mother liquor and pressurized gas. This causes the hydrogen mother liquor and pressurized gas to collide and impact each other, thereby dispersing and atomizing the hydrogen mother liquor, thus improving the atomization effect of the hydrogen mother liquor.
[0018] 5) A hydrogen mother liquor atomizing spray gun according to 3), wherein:
[0019] The atomizing disc has evenly distributed holes on its surface. In this invention, when the pressurized gas and hydrogen mother liquor pass through the holes in the atomizing disc, the pressurized gas and hydrogen mother liquor are compressed within the holes, causing the hydrogen mother liquor to come into contact with and mix with the pressurized gas. This causes the hydrogen mother liquor and pressurized gas to impact and collide with each other, thereby dispersing and atomizing the hydrogen mother liquor and improving its atomization effect.
[0020] Compared with the prior art, this utility model also has the following technical effects:
[0021] In this invention, pressurized gas and hydrogen mother liquor are introduced into the feeding chamber through the liquid inlet pipe and air inlet hole, respectively. The pressurized gas and hydrogen mother liquor pass through the through hole and enter the atomization chamber for initial mixing, completing the first atomization of the hydrogen mother liquor. Then, the pressurized gas and hydrogen mother liquor pass through the through hole, and are further mixed by the compression of the through hole, completing the second atomization of the hydrogen mother liquor. Then, the hydrogen mother liquor and pressurized gas enter the atomization chamber and move towards the nozzle. During the process of the hydrogen mother liquor and pressurized gas moving towards the nozzle, the hydrogen mother liquor and pressurized gas interact with the turbine. The fan blades contact each other, driving the turbine fan blades to rotate, which in turn drives the atomizing disc and the rotating rod to rotate. During the rotation of the turbine fan blades, atomizing disc, and rotating rod, the turbine fan blades, atomizing disc, and rotating rod agitate the hydrogen mother liquor and pressurized gas. When the hydrogen mother liquor and pressurized gas pass through the holes on the atomizing disc, the pressurized gas and hydrogen mother liquor are compressed within the holes, further promoting the contact and mixing of the hydrogen mother liquor and pressurized gas, completing the third atomization of the hydrogen mother liquor. The third atomization of the hydrogen mother liquor can improve the atomization effect of the hydrogen mother liquor, thereby improving the heating and flame-retardant effect of the hydrogen mother liquor on SO3.

[0034] See the example. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a chamber 1. One end of the chamber 1 is provided with an inlet pipe 2 for supplying hydrogen mother liquor into the chamber 1. The side of the chamber 1 near the inlet pipe 2 is provided with an air inlet 3 for supplying pressurized gas into the chamber 1. The other end of the chamber 1 is fitted with a nozzle 4 for supplying atomized hydrogen mother liquor. A fixing block 5 is provided inside the chamber 1. The fixing block 5 is located between the nozzle 4 and the inlet pipe 2. The side of the fixing block 5 facing the inlet pipe 2 and the air inlet 3 forms a feeding chamber with the inner wall of the chamber 1. The side of the fixing block 5 facing the nozzle 4 forms an atomization chamber with the inner wall of the chamber 1. The side of the fixing block 5 is provided with a through hole 6 connecting the atomization chamber and the feeding chamber. The atomization chamber is provided with an atomization structure to promote the contact and mixing of pressurized gas and hydrogen mother liquor.
[0035] In this embodiment, since the side of the fixing block 5 facing the air inlet 3 and the liquid inlet pipe 2 forms a feeding chamber with the inner wall of the chamber 1, when the pressurized gas and hydrogen mother liquor are introduced into the chamber 1 through the air inlet 3 and the liquid inlet pipe 2 respectively, the pressurized gas and hydrogen mother liquor enter the feeding chamber, then pass through the through hole 6 into the atomization chamber, move towards the nozzle 4, and are sprayed out from the nozzle 4.
[0036] During the process of pressurized gas and hydrogen mother liquor entering the feed chamber, the pressurized gas and hydrogen mother liquor are initially mixed in the feed chamber, causing the hydrogen mother liquor to impact and collide with each other, thus dispersing the hydrogen mother liquor and completing the first atomization of the hydrogen mother liquor. As the pressurized gas and hydrogen mother liquor pass through the through-hole 6, they are compressed within the through-hole 6, promoting further contact and mixing, completing the second atomization of the hydrogen mother liquor. As the pressurized gas and hydrogen mother liquor move towards the nozzle 4, they pass through the atomization structure in the atomization chamber. The atomization structure further promotes contact and mixing between the hydrogen mother liquor and the pressurized gas, completing the third atomization of the hydrogen mother liquor. This three-stage atomization of the hydrogen mother liquor improves the atomization effect, thereby enhancing the temperature-increasing and flame-retardant effect of the hydrogen mother liquor on SO3.
[0037] The end of the inlet pipe 2 located in the feed chamber is connected to a nozzle 7 for spraying out hydrogen mother liquor. In this embodiment, when hydrogen mother liquor is introduced into the feed chamber, the hydrogen mother liquor is sprayed into the through hole 6 through the nozzle 7 along the inlet pipe 2. At this time, the hydrogen mother liquor is dispersed into larger droplets by the nozzle 7, which can make more sufficient contact with the pressurized gas in the feed chamber, thereby improving the effect of initial mixing and atomization of hydrogen mother liquor and pressurized gas.
[0038] The atomizing structure includes a main rod 8 located in the atomizing chamber and extending along its axial direction. A rotating rod 9 is welded to the end of the main rod 8 facing the nozzle 4. The axis of the rotating rod 9 is perpendicular to the axis of the main rod 8. Slider blocks 10 are welded to both ends of the rotating rod 9. An annular groove is provided on the inner side wall of the chamber 1 for the slider 10 to move circumferentially along the chamber 1. The slider 10 is embedded in the annular groove. A rotating component that can drive the main rod 8 to rotate is welded to the end of the main rod 8 facing the through hole 6. Three atomizing discs 11 are provided on the main rod 8 to promote the contact and mixing of pressurized gas and hydrogen mother liquor. The three atomizing discs 11 are evenly arranged along the axial direction of the main rod 8 and located between the rotating component and the rotating rod 9.
[0039] In this embodiment, the pressurized gas and hydrogen mother liquor enter the atomizing chamber through the through hole 6 and then move towards the nozzle 4. During this process, the rotating component can drive the main rod 8 to rotate. During the rotation of the main rod 8, the main rod 8 drives the atomizing disk 11 to rotate. At the same time, the main rod 8 drives the rotating rod 9 to rotate. During the rotation of the rotating rod 9, the rotating rod 9 drives the slider 10 to move circumferentially along the chamber 1 in the annular groove.
[0040] During the process of the rotating rod 9 driving the slider 10 to move circumferentially along the chamber 1 within the annular groove, the mutual cooperation between the slider 10 and the annular groove ensures the stability of the rotating rod 9, main rod 8, rotating component, and atomizing disk 11 during rotation. During the rotation of the rotating component, atomizing disk 11, and rotating rod 9, the rotating component, atomizing disk 11, and rotating rod 9 can agitate the hydrogen mother liquor and pressurized gas, promoting the mixing of the hydrogen mother liquor and pressurized gas, and causing the hydrogen mother liquor and pressurized gas to collide and impact each other, thereby dispersing and atomizing the hydrogen mother liquor. When the hydrogen mother liquor and pressurized gas pass through the atomizing disk 11, the atomizing disk 11 can further promote the mixing of the hydrogen mother liquor and pressurized gas, improving the atomization effect of the hydrogen mother liquor.
[0041] The rotating component includes a shaft 12, one end of which is welded to the end of the main rod 8 facing the through hole 6, and the other end of the shaft 12 extends toward the through hole 6. Several turbine blades 13 are welded radially to the side of the shaft 12, and the several turbine blades 13 are evenly arranged around the circumference of the shaft 12.
[0042] In this embodiment, when the pressurized gas and hydrogen mother liquor enter the atomization chamber through the through hole 6, the pressurized gas and hydrogen mother liquor come into contact with the turbine blade 13, driving the turbine blade 13 to rotate. During the rotation of the turbine blade 13, the turbine blade 13 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the main rod 8 connected to it to rotate. During the rotation of the main rod 8, the main rod 8 drives the atomizing disk 11 and the rotating rod 9 connected to it to rotate. During the rotation of the turbine blade 13, the atomizing disk 11 and the rotating rod 9, the hydrogen mother liquor and the pressurized gas can be stirred, causing the hydrogen mother liquor and the pressurized gas to mix, so that the hydrogen mother liquor and the pressurized gas impact and collide with each other, thereby dispersing and atomizing the hydrogen mother liquor, and improving the atomization effect of the hydrogen mother liquor.
[0043] The surface of the atomizing disk 11 is uniformly provided with holes 14. In this embodiment, when the pressurized gas and the hydrogen mother liquid pass through the holes 14 on the atomizing disk 11, the pressurized gas and the hydrogen mother liquid are compressed in the holes 14, which causes the hydrogen mother liquid to come into contact with and mix with the pressurized gas. This causes the hydrogen mother liquid and the pressurized gas to impact and collide with each other, thereby dispersing and atomizing the hydrogen mother liquid and improving the atomization effect of the hydrogen mother liquid.
[0044] In this embodiment, pressurized gas and hydrogen mother liquor are introduced into the feeding chamber through the liquid inlet pipe 2 and the air inlet 3, respectively. The pressurized gas and hydrogen mother liquor pass through the through hole 6 and enter the atomization chamber for preliminary mixing, completing the first atomization of the hydrogen mother liquor. Then, the pressurized gas and hydrogen mother liquor pass through the through hole 6 and are further mixed by the compression of the through hole 6, completing the second atomization of the hydrogen mother liquor. Then, the hydrogen mother liquor and pressurized gas enter the atomization chamber and move towards the nozzle 4. During the process of moving towards the nozzle 4, the hydrogen mother liquor and pressurized gas come into contact with the turbine blades 13, pushing... The turbine blades 13 rotate, thereby driving the atomizing disk 11 and the rotating rod 9 to rotate. During the rotation of the turbine blades 13, atomizing disk 11 and rotating rod 9, the turbine blades 13, atomizing disk 11 and rotating rod 9 agitate the hydrogen mother liquor and pressurized gas. When the hydrogen mother liquor and pressurized gas pass through the holes 14 on the atomizing disk 11, the pressurized gas and hydrogen mother liquor are compressed in the holes 14, which further promotes the contact and mixing of the hydrogen mother liquor and pressurized gas, completing the third atomization of the hydrogen mother liquor. The three atomizations of the hydrogen mother liquor can improve the atomization effect of the hydrogen mother liquor, thereby improving the heating and flame retardant effect of the hydrogen mother liquor on SO3.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this solution. These modifications and improvements should also be considered within the scope of protection of this solution, and will not affect the effectiveness of the implementation of this solution or the practicality of the patent.
