[0001] The present application relates to the field of ammonia spray guns, and in particular to a high-efficiency and high-atomization ammonia spray gun. Background Art

[0002] The ammonia spray gun is an important component for denitrification of exhaust gas. It is mainly used in denitrification projects such as industrial boilers, heating boilers, and cement kilns. By spraying ammonia water into atomized form, it reacts with harmful substances in the exhaust gas to remove carbon dioxide, sulfur dioxide and other substances in the exhaust gas to meet emission standards.

However, it has the problem of poor atomization effect, a small spraying range, and inability to fully mix with the exhaust gas, resulting in carbon dioxide, sulfur dioxide and other substances in the exhaust gas being unable to effectively react with the ammonia, making its treatment effect worse. It also causes an increase in the use of ammonia, reduces the utilization efficiency of ammonia, and is not conducive to its use. Summary of the Invention

[0004] The purpose of this application is to provide a high-efficiency and highly atomized ammonia spray gun, which has the advantages of good spray effect, large spray range, increased contact area between ammonia and exhaust gas, increased purification effect on exhaust gas, and improved ammonia utilization efficiency.

[0005] To achieve the above-mentioned purpose, the present application also provides a high-efficiency and high-atomization ammonia spray gun, including a pipeline, the left end of the pipeline is connected to a liquid chamber, the left end of the liquid chamber is provided with a main nozzle, the surface of the main nozzle is connected to a side nozzle, the right end of the main nozzle is connected to a rotating tube, the right side of the rotating tube passes through the inner cavity of the liquid chamber and is sleeved with an impeller, the surface of the rotating tube is movably connected to the liquid chamber through a first bearing, the surface of the rotating tube and the inner cavity of the liquid chamber are provided with a water inlet, the surface of the pipeline is sleeved with a rotating sleeve, the surface of the rotating sleeve is fixedly connected with teeth and fan blades from left to right in sequence, the bottom of the liquid chamber is fixedly connected to a motor, the right side of the motor output end is fixedly connected to a gear, the top of the gear is engaged with the teeth, and a dust-proof component is fixedly connected between the top and bottom of the inner cavity of the main nozzle.

[0007] Preferably, a water-permeable hole is opened on the left side of the limiting plate, a sealing rubber pad is fixedly connected to the surface of the conical block, and both sides of the spring are fixedly connected to the sealing ring and the limiting plate respectively.

[0008] Preferably, the surface of the pipe is movably connected to the rotating sleeve via a second bearing, and the motor is fixedly connected to the liquid chamber via a mounting seat.

[0009] Preferably, a mounting plate is movably connected to the right side of the rotating tube, the bottom of the mounting plate is fixedly connected to the inner wall of the liquid chamber, and a conical guide block is fixedly connected to the right side of the mounting plate.

[0010] Preferably, the number of the side nozzles is four and they are evenly distributed on the surface of the main nozzle, and the side nozzles are set at an angle of 45°.

[0011] Preferably, the surface of the rotating tube is fixedly connected to the impeller, and the right side of the main nozzle is connected to the surface of the rotating tube via a thread.

[0012] Compared with the prior art, the beneficial effects of this invention are:

[0013] 1. By arranging a liquid chamber, a main nozzle, a side nozzle, a rotating tube, an impeller, a water inlet, a rotating sleeve, teeth, fan blades, a motor, a gear and an anti-dust component, the main nozzle and the side nozzle can be rotated when spraying ammonia water to increase the atomization effect. At the same time, the main nozzle plus the side nozzle are used for spraying to increase the atomization amount of ammonia water and improve its contact range with the exhaust gas. The rotating fan blades are used to blow the ammonia water mist to a distant place to increase its coverage range.

[0014] 2. The second bearing can be provided to enable the rotating sleeve to rotate smoothly, the mounting seat can be provided to increase the stability of the motor after installation and fixation, the mounting plate can be provided to facilitate the installation of the rotating tube, improve its stability during rotation, and prevent it from shaking during rotation, and the conical guide block can be provided to enable ammonia water to quickly enter the liquid chamber, and the four side nozzles can be provided to increase the spraying amount of ammonia water mist and improve its contact range with the exhaust gas, and the side nozzles set at a 45° angle can prevent them from interfering with the spraying work of the main nozzle, and the thread can facilitate the disassembly and assembly of the main nozzle. The sealing ring is sealed by the conical block. When the main nozzle is not working, external impurities and dust cannot enter the liquid chamber and the pipeline, and can only adhere to the nozzle of the main nozzle. When the main nozzle is working, the high-pressure ammonia water pushes the conical block, which drives the limit plate to squeeze the spring. At this time, the conical block does not contact the sealing ring and leaks out of the gap. The ammonia water can pass through the sealing ring quickly. At the same time, the conical block can be used to divert part of the ammonia water to prevent the main nozzle from spraying too much, which will cause the side nozzle pressure to decrease. By setting the water permeable hole, the limit plate can be prevented from reducing the flow rate. By setting the sealing rubber pad, the sealing effect of the conical block can be increased.

[0025] Embodiment 1: By setting a liquid chamber 2, a main nozzle 3, a side nozzle 4, a rotating tube 5, an impeller 6, a water inlet 7, a rotating sleeve 8, teeth 9, fan blades 10, a motor 11, a gear 12 and an anti-dust component 13, the main nozzle 3 and the side nozzle 4 can be rotated when spraying ammonia water, so as to increase the atomization effect. At the same time, the main nozzle 3 plus the side nozzle 4 are used for spraying, which increases the atomization amount of ammonia water and improves its contact range with the exhaust gas. The rotating fan blades 10 are used to blow the ammonia water mist to a distance to increase its coverage range.

[0026] In one possible implementation, see Figure 1-5 , a high-efficiency and high-atomization ammonia spray gun, the surface of the pipe 1 is movably connected to the rotating sleeve 8 through the second bearing, the motor 11 is fixedly connected to the liquid chamber 2 through the mounting seat, the right side of the rotating tube 5 is movably connected with the mounting plate 14, the bottom of the mounting plate 14 is fixedly connected to the inner wall of the liquid chamber 2, and the right side of the mounting plate 14 is fixedly connected to a conical guide block. There are four side nozzles 4, and they are evenly distributed on the surface of the main nozzle 3. The side nozzles 4 are set at an angle of 45°. The surface of the rotating tube 5 is fixedly connected to the impeller 6, and the right side of the main nozzle 3 is connected to the surface of the rotating tube 5 by a thread.

[0027] Embodiment 2: By providing a second bearing, the rotating sleeve 8 can rotate smoothly, by providing a mounting seat, the stability of the motor 11 after installation and fixation can be increased, by providing a mounting plate 14, the rotating tube 5 can be easily installed, and its stability during rotation can be improved, and it can be prevented from shaking during rotation. By providing a conical guide block, ammonia water can quickly enter the liquid chamber 2, and by providing four side nozzles 4, the spraying amount of ammonia water mist can be increased, and its contact range with the exhaust gas can be increased. The side nozzle 4 set at an angle of 45° can prevent it from interfering with the spraying work of the main nozzle 3, and by providing a thread, the disassembly and assembly of the main nozzle 3 can be facilitated.

[0028] On the basis of Example 1, this embodiment describes the dust-proof component 13 mechanism in Example 1. The dust-proof component 13 includes a sealing ring 1301. A conical block 1302 is provided on the left side of the sealing ring 1301. The right end of the conical block 1302 extends to the right side of the sealing ring 1301 and is sleeved with a spring 1303. The right side of the conical block 1302 is fixedly connected to a limiting plate 1304. A water-permeable hole is provided on the left side of the limiting plate 1304. A sealing rubber pad is fixedly connected to the surface of the conical block 1302. Both sides of the spring 1303 are fixedly connected to the sealing ring 1301 and the limiting plate 1304 respectively. The sealing ring 1301 is sealed by the conical block 1302. When the main nozzle 3 is not working, external impurities and dust cannot enter the liquid chamber 2 and the pipeline 1, and can only adhere to the nozzle of the main nozzle 3. When the main nozzle 3 is working, the high-pressure ammonia water pushes the conical block 1302, so that it drives the limit plate 1304 to squeeze the spring 1303. At this time, the conical block 1302 does not contact the sealing ring 1301 and leaks out of the gap. The ammonia water can quickly pass through the sealing ring 1301. At the same time, the conical block 1302 can be used to divert part of the ammonia water to prevent the main nozzle 3 from spraying too much, which will cause the side nozzle 4 to reduce pressure. By setting a water-permeable hole, the limit plate 1304 can be prevented from reducing the flow rate. By setting a sealing rubber pad, the sealing effect of the conical block 1302 can be increased.

[0029] Working principle: The pressurized ammonia water is transported to the liquid chamber 2 through the pipeline 1. After entering the liquid chamber 2, the ammonia water enters the rotating tube 5 and the main nozzle 3 through the water inlet 7 on the surface of the rotating tube 5. Under the impetus of the high-speed flow of ammonia water, the impeller 6 drives the rotating tube 5 to rotate, and the rotation of the rotating tube 5 drives the main nozzle 3 and the side nozzle 4 to rotate. At the same time, after the ammonia water enters the main nozzle 3, it pushes the conical block 1302, so that the conical block 1302 drives the limit plate 1304 to squeeze the spring 1303. At this time, the conical block 1302 no longer contacts the sealing ring 1301 and leaks out of the gap. The ammonia water passes through the gap and is discharged by the main nozzle. The main nozzle 3 is sprayed out, and at the same time, part of the ammonia water enters the side nozzle 4 and is sprayed out by the side nozzle 4. The multi-nozzle design of the main nozzle 3 plus the side nozzle 4 can increase the spraying amount of the ammonia water, increase the contact area between the atomized ammonia water and the exhaust gas, and at the same time, the rotating main nozzle 3 and the side nozzle 4 increase the atomization effect. The motor 11 is turned on, and the motor 11 cooperates with the gear 12 to drive the teeth 9 and the rotating sleeve 8 to rotate. The rotation of the rotating sleeve 8 drives the fan blades 10 to rotate, and the fan blades 10 blow the atomized ammonia water to a distant place to increase its coverage range. The above steps improve the atomization effect of the ammonia water and increase the utilization efficiency of the ammonia water.
