DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 7 The present embodiment provides a cyclonic gas-liquid coupled hazardous waste incineration quenching spray gun, comprising a gun barrel 10, a first semi-arc shell 20, an air supply assembly 30, an atomizing assembly 40, a second semi-arc shell 50 and a water supply assembly 60, wherein a central tube 103 is fixedly arranged inside the gun barrel 10 along the axial direction, and the central tube 103 passes through the gun barrel 10, and a liquid inlet hard tube 101 is arranged at one end of the gun barrel 10 located outside the combustion chamber, and a plurality of spray holes 102 are opened at one end of the gun barrel 10 located inside the combustion chamber, and the plurality of spray holes 102 are distributed in an annular manner around the central tube 103, and one end of the atomizing assembly 40 is connected from the central tube 103 to the atomizing assembly 40. The interior passes through and extends to the outside of the plurality of spray holes 102, and is used for atomizing the waste liquid sprayed through the plurality of spray holes 102. The first semi-arc shell 20 and the second semi-arc shell 50 are clamped on the outside of the gun barrel 10. An air-cooling chamber is formed between the first semi-arc shell 20 and the gun barrel 10, and a water-cooling chamber is formed between the second semi-arc shell 50 and the gun barrel 10. The air supply assembly 30 is installed at one end of the first semi-arc shell 20 for supplying air to the inside of the air-cooling chamber, and the water supply assembly 60 is installed at one end of the second semi-arc shell 50 for supplying water to the inside of the water-cooling chamber.

[0020] When it is necessary to incinerate and purify the hazardous waste liquid, an external pumping system (not shown in the figure) can be used to pump the hazardous waste liquid into the gun barrel 10 through the liquid inlet hard pipe 101. After the hazardous waste liquid is pumped into the gun barrel 10, it is sprayed out through a plurality of spray holes 102 at one end of the gun barrel 10 inside the combustion chamber. The sprayed hazardous waste liquid is atomized by the atomization component 40 and enters the combustion chamber, thereby being burned and purified. In the above process, air is supplied to the air-cooling chamber inside the first semi-arc shell 20 through the air supply component 30. After the air enters the air-cooling chamber, the gun barrel 10 can be air-cooled. At the same time, water is supplied to the water-cooling chamber inside the second semi-arc shell 50 through the water supply component 60. After the water enters the water-cooling chamber, the gun barrel 10 can be water-cooled. By air-cooling and water-cooling the gun barrel 10, the gun barrel 10 can be effectively prevented from being affected by the high temperature inside the combustion chamber, the gun barrel 10 can be prevented from being burned, and the service life of the gun barrel 10 is increased.

[0021] See also Figure 1 In one embodiment, the atomization assembly 40 includes an atomization motor 401, a drive shaft 402 and an atomization rod 404, the atomization motor 401 is arranged at one end of the barrel 10 located outside the combustion chamber, one end of the drive shaft 402 is connected to the output end of the atomization motor 401, and the other end passes through the center tube 103 and extends to the outside of one end of the barrel 10 located inside the combustion chamber, the atomization rod 404 is provided with a plurality of groups, a plurality of the atomization rods 404 are fixedly arranged on the side wall of the shaft body of the drive shaft 402 at one end inside the combustion chamber, a plurality of the atomization rods 404 are distributed in an annular manner on the side wall of the shaft body of the drive shaft 402, and a plurality of the atomization rods 404 are distributed relative to a plurality of the spray holes 102.

[0022] When the external pumping system pumps the hazardous waste liquid into the barrel 10 and the hazardous waste liquid is sprayed out from the plurality of spray holes 102, the drive shaft 402 is driven to rotate by the atomizing motor 401, thereby driving the plurality of atomizing rods 404 to rotate. When the plurality of atomizing rods 404 rotate, the hazardous waste liquid column flow sprayed out from the plurality of spray holes 102 is sheared and struck, so that the hazardous waste liquid column flow is fully atomized, so as to improve the incineration effect of the hazardous waste liquid.

[0023] Please continue reading Figure 1In one embodiment, a rotating disk 403 is fixedly provided on the side wall of the driving shaft 402, and the rotating disk 403 is arranged obliquely. An exhaust pipe 201 is provided at one end of the first semi-arc shell 20. The air supply assembly 30 includes an air inlet pipe 301, a first piston sleeve 302, a first piston rod 303 and a first extension rod 304. The first piston sleeve is fixedly installed at one end of the first semi-arc shell 20 and communicates with the air cooling chamber. One end of the first piston rod 303 extends to the inside of the first piston sleeve 302 and communicates with the air cooling chamber. The first piston sleeve 302 is telescopically matched, and the other end extends to the side of the turntable 403. The air inlet pipe 301 is arranged on the side wall of the first piston sleeve 302. The first extension rod 304 is provided with two groups. The two groups of the first extension rods 304 are fixedly arranged on the side wall of the first piston rod 303 and distributed at intervals. The ends of the two groups of the first extension rods 304 away from the first piston rod 303 extend to the opposite sides of the turntable 403 respectively. The air inlet pipe 301 and the first piston sleeve 302 are both provided with a one-way valve.

[0024] While the atomizing motor 401 drives the driving shaft 402 to rotate to atomize the hazardous waste liquid column flow sprayed through the plurality of spray holes 102, the driving shaft 402 can also drive the rotating disk 403 to rotate. Since the rotating disk 403 is arranged at an angle, when the rotating disk 403 rotates, it can act on the two groups of first extension rods 304 and then drive the first piston rod 303 to perform telescopic movement compared with the first piston sleeve 302. When the first piston rod 303 is extended compared with the first piston sleeve 302, the first piston rod 303 draws external air into the first piston sleeve 302 through the air intake pipe 301. When the first piston rod 303 is shortened compared with the first piston sleeve 302, the first piston rod 303 presses the air inside the first piston sleeve 302 to the inside of the air cooling chamber. After the air enters the inside of the air cooling chamber, it is discharged from the exhaust pipe 201. In this process, the air takes away the heat generated by the combustion of the gun barrel 10, thereby realizing air cooling of the gun barrel 10.

[0025] Please continue reading Figure 1In one embodiment, a drain pipe 501 is provided at one end of the second semi-arc shell 50, and the water supply assembly 60 includes a water inlet pipe 601, a second piston sleeve 602, a second piston rod 603 and a second extension rod 604. The second piston sleeve 602 is fixedly installed at one end of the second semi-arc shell 20 and communicates with the water cooling chamber. One end of the second piston rod 603 extends to the inside of the second piston sleeve 602 and telescopically cooperates with the second piston sleeve 602, and the other end extends to the side of the rotating disk 403. One end of the water inlet pipe 601 is connected to an external water tank (not shown in the figure), and the other end is connected to the second piston sleeve 602. The second extension rod 604 is provided with two groups, and the two groups of the second extension rod 604 are fixedly arranged on the side wall of the second piston rod 603 and are spaced apart. The ends of the two groups of the second extension rod 604 away from the second piston rod 603 extend to the opposite sides of the rotating disk 403 respectively, and a one-way valve is provided inside the water inlet pipe 601 and the second piston sleeve 602.

[0026] While the drive shaft 402 drives the turntable 403 to rotate and thereby drives the first piston rod 303 to perform telescopic movement compared to the first piston sleeve 302, the turntable 403 can also act on the two sets of second extension rods 604 to thereby drive the second piston rod 603 to perform telescopic movement compared to the second piston sleeve 602. When the second piston rod 603 is extended compared to the second piston sleeve 602, the second piston rod 603 draws water from the external water tank into the second piston sleeve 602 through the water inlet pipe 601. When the second piston rod 603 is shortened compared to the second piston sleeve 602, the second piston rod 603 presses the water inside the second piston sleeve 602 to the inside of the water-cooling chamber. After the water enters the inside of the water-cooling chamber, it is discharged from the drain pipe 501. In this process, the water takes away the heat generated by the gun barrel 10 during combustion, thereby realizing water-cooling of the gun barrel 10.

[0027] In one embodiment, the end of the drain pipe 501 away from the second semi-arc shell 50 is connected to an external water tank, so that the water source with the heat of the barrel 10 can flow back to the external water tank after being discharged from the drain pipe 501, thereby realizing the recycling of water.

[0028] In one embodiment, the drain pipe 501 can be an S-shaped elbow structure or a coil structure, which is not limited here. By setting the drain pipe 501 in an S-shaped elbow structure or a coil structure, the water source carrying the heat of the gun barrel 10 can obtain a longer external flow stroke during the process of returning the water source along the drain pipe 501 to the inside of the external water tank, so that the heat in the water source can fully pass through the wall of the drain pipe 501 to exchange heat with the external environment, so that the water source can be fully cooled before returning to the external water tank, thereby ensuring that the temperature of the water source returning to the outside water tank is low, so that the water source can improve the water cooling effect of the gun barrel 10 during the subsequent recycling process.

[0029] See also Figure 5 as well as Figure 6 In one embodiment, a cleaning assembly 70 is further provided inside the gun barrel 10. After the hazardous waste liquid is incinerated, the cleaning assembly 70 is used to clean the residual hazardous waste liquid inside the gun barrel 10 to prevent the hazardous waste liquid from remaining inside the gun barrel 10 for a long time and to prevent the hazardous waste liquid from causing corrosion damage to the gun barrel 10.

[0030] Please continue reading Figure 5 as well as Figure 6 In one embodiment, the cleaning assembly 70 includes a cleaning piston 701 and an elastic member 702. The cleaning piston 701 is annular in structure. The circumferential outer wall of the cleaning piston 701 is in contact with the inner wall of the gun barrel 10. The circumferential inner wall of the cleaning piston 701 is in contact with the outer wall of the center tube 103. The cleaning piston 701 can slide between the gun barrel 10 and the center tube 103. One end of the elastic member 702 is connected to the inner wall of one end of the gun barrel 10 away from the plurality of spray holes 102, and the other end is connected to the cleaning piston 701, so as to provide elastic support for the cleaning piston 701. A pipeline 703 is provided on the cleaning piston 701. One end of the liquid inlet hard pipe 101 extends into the interior of the gun barrel 10 and is connected to a liquid inlet hose 105. One end of the liquid inlet hose 105 away from the liquid inlet hard pipe 101 is connected to the pipeline 703.

[0031] When the cleaning piston 701 is in a state of blocking the nozzles 102, the liquid inlet hose 105 is in an extended state. When the external pumping system pumps the hazardous waste liquid, the hazardous waste liquid enters the liquid inlet hose 105 through the liquid inlet hard pipe 101, and then enters the pipe 703 through the liquid inlet hose 105, and finally is output from the pipe 703 to the inside of the barrel 10. At this time, the hazardous waste liquid enters one side of the cleaning piston 701, and the cleaning piston 701 slides along the inside of the barrel 10 under the pressure of the hazardous waste liquid. The cleaning piston 701 is away from the nozzles 102, and the elastic member 702 is compressed. When the cleaning piston 701 slides to a certain position, the pressure of the hazardous waste liquid on one side of the cleaning piston 701 and the elastic supporting force of the elastic member 702 make the cleaning piston 701 balanced and remain stationary. 102 and enter the combustion chamber for incineration. When the hazardous waste liquid is incinerated, the pumping system stops working. At this time, the pressure on one side of the cleaning piston 701 is reduced, and the elastic member 702 pushes the cleaning piston 701 to make the cleaning piston 701 slide in the opposite direction along the inside of the gun barrel 10. When the cleaning piston 701 slides in the opposite direction, a small amount of hazardous waste liquid remaining on one side thereof continues to be pushed out from the plurality of spray holes 102, thereby avoiding a small amount of hazardous waste liquid from being retained in the gun barrel 10 for a long time and preventing the hazardous waste liquid from corroding the gun barrel 10. When the cleaning piston 701 slides in the opposite direction and contacts the inner wall of the gun barrel 10 again, the cleaning piston 701 blocks the plurality of spray holes 102, thereby preventing dust and debris in the combustion chamber from entering the gun barrel 10 from the plurality of spray holes 102 and preventing the gun barrel 10 from being blocked, thereby ensuring that the subsequent hazardous waste liquid can continue to be sprayed out from the plurality of spray holes 102 smoothly and realizing the subsequent smooth incineration of the hazardous waste liquid.

[0032] In one embodiment, a plurality of sealing rods (not shown in the figure) are fixedly provided on one side of the cleaning piston 701 facing the plurality of spray holes 102 , and the plurality of sealing rods correspond to the plurality of spray holes 102 one by one.

[0033] When the cleaning piston 701 slides in the opposite direction along the inside of the gun barrel 10 and abuts against the inner wall of the gun barrel 10, a plurality of sealing rods on one side of the cleaning piston 701 can be inserted into a plurality of spray holes 102 one by one, thereby sealing the plurality of spray holes 102, thereby preventing dust and debris inside the combustion chamber from entering the spray holes 102, and avoiding dust and debris from clogging the spray holes 102.

[0034] In one embodiment, the elastic member 702 may be a spring or a metal spring, which is not limited here.

[0035] In one embodiment, the liquid inlet hose 105 can be a metal bellows or a rubber hose, which is not limited here.

[0036] See also Figure 6 In one embodiment, an annular baffle 104 is fixedly provided on the inner wall of the gun barrel 10 .

[0037] When the hazardous waste liquid enters the interior of the gun barrel 10 through the pipe 703, the hazardous waste liquid can push the cleaning piston 701 to slide along the interior of the gun barrel 10. When the cleaning piston 701 slides to abut against the annular baffle 104, the cleaning piston 701 remains stationary. At this time, the hazardous waste liquid that subsequently enters the interior of the gun barrel 10 through the pipe 703 can be stably sprayed out from the plurality of spray holes 102. At the same time, the sprayed hazardous waste liquid has a certain pressure and is initially atomized. The initially atomized hazardous waste liquid is further sheared and broken up under the rotation of the plurality of atomizing rods 401, so that the hazardous waste liquid is further atomized.

[0038] The working principle of the present invention is as follows: the hazardous waste liquid to be incinerated is pumped into the barrel 10 through the liquid inlet hard pipe 101, the liquid inlet hose 105 and the pipeline 703 through the external pumping system, and the hazardous waste liquid pushes the cleaning piston 701 so that the cleaning piston 701 slides along the inside of the barrel 10. When the cleaning piston 701 slides to abut against the annular baffle 104, the cleaning piston 701 remains stationary, and then the hazardous waste liquid that subsequently enters the barrel 10 is sprayed into the combustion chamber through the plurality of spray holes 102 for incineration treatment; while the hazardous waste liquid is sprayed out from the plurality of spray holes 102, the drive shaft 402 is driven to rotate by the atomizing motor 401, and when the drive shaft 402 rotates, the turntable 403 and the plurality of atomizing rods 404 can be driven to rotate synchronously, and when the plurality of atomizing rods 404 rotate, the columnar flow of the hazardous waste liquid sprayed from the plurality of spray holes 102 is sheared and broken up, so that the hazardous waste liquid is atomized into fine droplets, so that the hazardous waste liquid can be fully incinerated, and when the above-mentioned turntable 403 rotates The first piston rod 303 and the second piston rod 603 can be driven to telescopically move respectively by cooperating with the two groups of first extension rods 304 and the two groups of second extension rods 604. When the first piston rod 303 telescopically moves, the outside air is continuously pressed and sent to the air-cooling chamber inside the first semi-arc shell 20, and the outside air is continuously discharged by the exhaust pipe 201, so that there is always air circulation in the air-cooling chamber inside the first semi-arc shell 201, thereby realizing air-cooling of the gun barrel 10. When the second piston rod 603 telescopically moves, the water source in the external water tank is continuously pressed and sent to the water-cooling chamber inside the second semi-arc shell 50, and the water source is continuously discharged by the drain pipe 501, so that there is always water source flowing in the water-cooling chamber inside the second semi-arc shell 50, thereby realizing water-cooling of the gun barrel 10. Through the cooling method of the dual combination of air cooling and water cooling of the above-mentioned gun barrel 10, the cooling effect of the gun barrel 10 can be greatly improved, thereby improving the service life of the gun barrel 10.

[0039] In the embodiment of the present invention, when it is necessary to incinerate and purify the hazardous waste liquid, an external pumping system (not shown in the figure) can be used to pump the hazardous waste liquid into the gun barrel 10 through the liquid inlet hard pipe 101. After the hazardous waste liquid is pumped into the gun barrel 10, it is sprayed out through a plurality of spray holes 102 at one end of the gun barrel 10 inside the combustion chamber. The sprayed hazardous waste liquid is atomized by the atomizing component 40 and enters the combustion chamber, thereby being burned and purified. In the above process, air is supplied to the air cooling chamber inside the first semi-arc shell 20 through the air supply component 30. After the air enters the air cooling chamber, the gun barrel 10 can be air-cooled. At the same time, a water supply assembly 60 is used to supply water to the inside of the water-cooling chamber inside the second semi-arc-shaped shell 50. After the water enters the water-cooling chamber, the gun barrel 10 can be water-cooled. By air-cooling and water-cooling the gun barrel 10, the gun barrel 10 can be effectively prevented from being affected by the high temperature inside the combustion chamber, and the gun barrel 10 can be prevented from being burned, thereby increasing the service life of the gun barrel 10. Compared with the prior art, when the hazardous waste liquid is incinerated, the gun barrel 10 can be air-cooled and water-cooled, so that the gun barrel 10 obtains a double cooling effect, thereby improving the protection effect of the gun barrel 10 and increasing the service life of the gun barrel 10.
