Description

Technical Field

[0001] The present application relates to the technical field of wastewater treatment equipment, and in particular to an atomized liquid incineration device for a saline wastewater pyrolysis device. Background Art

[0002] Saline wastewater mainly comes from chemical plants, the collection and processing of oil and natural gas, etc. This kind of wastewater is usually a mixed liquid of organic and inorganic substances, and the inorganic substances in it are mainly alkali metal salts, which cause great harm to the environment. The waste liquid incineration technology is the main treatment method for this waste liquid.

[0003] The waste liquid incineration technology is a process in which saline wastewater is quantitatively sprayed into an incinerator through an atomizer. After atomization, the wastewater vaporizes at high temperature, and the alkali metal salts in the wastewater are dispersed in the flue gas as micron-sized particles. During the flow of the flue gas, the alkali metal salts of the micron-sized particles touch the furnace wall and aggregate into a fluid molten salt, and the molten salt flows along the furnace wall to the quenching tank at the bottom of the furnace and dissolves in the water inside the quenching tank.

[0004] Among them, the atomization effect of saline wastewater is directly proportional to the treatment effect of the wastewater. Therefore, the atomization nozzle holes on the atomizer are usually designed to be very small. However, the atomizer itself is located inside the incinerator. When the atomizer stops spraying saline wastewater, the residual high temperature inside the incinerator will cause the saline wastewater attached to the atomization nozzle holes of the atomizer to crystallize. The crystallized metal salts will block the atomization nozzles of the atomizer, resulting in a poor subsequent spraying effect of the atomizer, which has deficiencies. Summary of the Invention

[0005] In order to improve the problem that the atomization nozzles of the atomizer are blocked by the crystallization of saline wastewater, resulting in a poor atomization effect of saline wastewater, the present application provides an atomized liquid incineration device for a saline wastewater pyrolysis device.

[0006] The atomized liquid incineration device for a saline wastewater pyrolysis device provided by the present application adopts the following technical solutions:

[0007] An atomizing liquid incineration device for a saline wastewater pyrolysis device, comprising an end plate disc, an outer tube and an inner tube. The inner tube is arranged on the end plate disc, the outer tube is coaxially sleeved on the inner tube, the inner diameter of the outer tube is larger than the outer diameter of the inner tube, the outer tube is used for introducing gas, the inner tube is used for introducing saline wastewater, a hollow atomizing shell with an open side facing the end plate disc is detachably arranged on the end plate disc, a plurality of atomizing holes are formed in the atomizing shell, a needle plate is slidably arranged between the atomizing shell and the end plate disc, a plurality of through-hole needles are arranged on the needle plate, and the through-hole needles correspond to the atomizing holes one by one. A dredging assembly for driving the needle plate to slide is arranged on the end plate disc. An air vent ring groove is formed in the end plate disc between the outer tube and the inner tube, and the air vent ring groove is used for communicating the outer tube with the inside of the atomizing shell. A liquid flow hole is formed in the end plate disc, and the liquid flow hole is used for communicating the inner tube with the inside of the atomizing shell.

[0008] By adopting the above technical solution, the dredging assembly first drives the needle plate to move, so that the through-hole needles on the needle plate are inserted into the atomizing holes, thereby dredging the metal salts crystallized in the atomizing holes. Then the worker introduces saline wastewater into the inner tube and introduces gas between the outer tube and the inner tube. The saline wastewater flows into the atomizing shell through the liquid flow hole, and the gas flows into the atomizing shell through the air vent ring groove. The saline wastewater and the gas will be pressurized in the atomizing shell and sprayed into the incinerator through the atomizing holes. The saline wastewater forms misty small water droplets under the combined action of the atomizing holes and the gas. The high temperature in the incinerator will quickly ignite the gas. At the same time, the high temperature in the incinerator and the ignited gas will quickly evaporate and incinerate the atomized saline wastewater small water droplets to form molten metal salts. The molten metal salts will flow along the furnace wall to the quenching tank at the bottom of the furnace. By dredging the atomizing holes with the through-hole needles before incineration, the situation that the atomizing effect of the saline wastewater becomes poor due to the crystallization and blockage of the atomizing holes by the metal salts is reduced, which is beneficial to improving the incineration effect of the saline wastewater.

[0009] Optionally, the dredging assembly includes a driving ring coaxially and rotatably arranged on the end plate disc, a rotating member for driving the driving ring to rotate is arranged on the end plate disc, a dredging ring is coaxially arranged on the driving ring, a push rod parallel to the axis of the end plate disc is arranged on the needle plate, a dredging compression spring is propped between the push rod and the end plate disc, a cross bar is arranged on the push rod between the dredging ring and the end plate disc, the cross bar abuts against the dredging ring, and a dredging notch with a triangular cross section is formed on one side of the dredging ring facing the cross bar. When the cross bar abuts against the dredging notch, the through-hole needles are inserted into the atomizing holes.

[0010] By adopting the above technical solution, the dredging compression spring presses the cross bar against the dredging ring through the ejector rod. During the process of the rotating member driving the active ring to rotate, the active ring drives the dredging ring to rotate synchronously. The cross bar abuts against the surface of the dredging ring until the dredging notch on the dredging ring rotates above the cross bar. The dredging compression spring restores its deformation and pushes the cross bar to be stuck on the dredging notch. The ejector rod pushes the dredging needle on the needle plate into the atomization hole on the atomization shell. At this time, the end of the dredging needle is flush with the side of the atomization shell facing away from the end plate disc. The crystal formed in the atomization hole is discharged. As the active ring continues to rotate, the cross bar gradually slides out along the triangular inclined surface of the dredging notch. During this process, the dredging compression spring is compressed again, and the needle plate drives the dredging needle to disengage from the atomization hole and reset.

[0011] Optionally, the rotating member includes a plurality of hole-changing blocks slidably arranged on the active ring. The plurality of hole-changing blocks are evenly distributed circumferentially along the axis of the active ring. The hole-changing blocks slide in the radial direction along the axis of the active ring. The active ring is provided with hole-changing grooves for the hole-changing blocks to slide. A hole-changing compression spring is propped between one end of the hole-changing block facing away from the axis of the end plate disc and the hole-changing groove on the active ring. The active ring is provided with a plurality of exhaust holes, and the exhaust holes correspond to and communicate with the hole-changing grooves one by one. The plurality of exhaust holes are arranged obliquely circumferentially along the axis of the active ring. The hole-changing block is provided with a rotating hole for communicating the exhaust hole with the ventilation ring groove, and the hole-changing block is provided with a ventilation hole for communicating the ventilation ring groove with the inside of the atomization shell. The end plate disc is provided with a hole-changing assembly for driving the hole-changing block to slide.

[0012] By adopting the above technical solution, the hole-changing assembly drives the hole-changing block to slide. The hole-changing compression spring pushes the hole-changing block and makes the rotating hole on the hole-changing block communicate with the exhaust hole and the ventilation ring groove at the same time. The gas flows to the incinerator along the directions of the ventilation ring groove, the rotating hole and the exhaust hole. The gas flowing out of the exhaust hole is ignited by the high temperature in the incinerator. Since the exhaust holes are arranged obliquely, the gas discharged from the exhaust holes and the ignited gas push the active ring to rotate around the axis of the end plate disc, so that the active ring drives the dredging ring to rotate synchronously.

[0013] Optionally, the hole-changing assembly includes a plurality of inner driving blocks slidably arranged on the end plate disc. The inner driving blocks slide in the radial direction along the axis of the end plate disc. The end plate disc is provided with a plurality of inner driving grooves for the inner driving blocks to slide. The inner driving grooves correspond to the inner driving blocks one by one. The inner driving grooves are used to communicate with the hole-changing grooves and correspond to them one by one. A inner driving compression spring is propped between one end of the inner driving block facing away from the axis of the end plate disc and the inner driving groove. The inner driving block is provided with a liquid passing hole for communicating the liquid flowing hole with the inside of the atomization shell. When the liquid passing hole communicates with the liquid flowing hole, the ventilation hole communicates with the ventilation ring groove. The end plate disc is provided with a sliding member for driving the inner driving block to slide.

[0014] By adopting the above technical solution, the sliding member drives the inner driving block to have a tendency to slide. The inner driving block abuts against the inner ring side wall of the driving ring during rotation until the inner driving block abuts against the hole-changing block. The inner driving block will slide into the hole-changing groove. During this process, the hole-changing block slides and squeezes the hole-changing compression spring, and the inner driving block squeezes the inner driving compression spring. The hole-changing compression spring and the inner driving compression spring are simultaneously compressed and deformed until the liquid through hole on the inner driving block communicates with the liquid flow hole, and the air vent hole on the hole-changing block communicates with the air vent ring groove. At this time, gas and salt-containing wastewater flow into the atomization shell simultaneously.

[0015] Optionally, the sliding member includes a driving tube that slides coaxially and passes through the end plate. Driven cone rings and driving cone rings are coaxially arranged at both ends of the driving tube respectively. The driven cone ring and the driving cone ring are symmetrical about the driving tube. The diameter of the driven cone ring gradually increases along the direction from the atomization shell to the end plate. An inner driving rod is arranged on the inner driving block, and the inner driving rod abuts against the conical surface of the driven cone ring. The driving cone ring is located inside the inner tube. A first bracket is arranged on the inner tube, and the driving tube slides through the first bracket. A driving compression spring is propped between the first bracket and the driving cone ring. A water sealing ring plate is coaxially arranged on the inner tube, and the conical surface of the driving cone ring is used to abut against the inner ring of the water sealing ring plate.

[0016] By adopting the above technical solution, the salt-containing wastewater flowing into the inner tube will push the driving cone ring. The driving cone ring squeezes the driving compression spring and gradually separates from the water sealing ring plate. The salt-containing wastewater flows in from the inner ring of the water sealing ring plate. At the same time, the driving cone ring drives the driven cone ring to move synchronously through the driving tube. The driven cone ring pushes the inner driving rod. Under the action of the conical surface of the driven cone ring, the inner driving rod drives the inner driving block to squeeze the inner driving compression spring, so as to realize the function of driving the inner driving block to slide.

[0017] Optionally, a slag cleaning shaft is coaxially and rotatably arranged in the driving tube. The slag cleaning shaft rotates through the atomization shell. A scraper is arranged on the slag cleaning shaft, and the scraper is attached to the side of the atomization shell facing away from the end plate. A slag cleaning member for driving the slag cleaning shaft to rotate is arranged on the inner tube.

[0018] By adopting the above technical solution, the slag cleaning member drives the slag cleaning shaft to rotate. The rotating slag cleaning shaft drives the scraper to scrape off the crystallized metal salts accumulated on the atomization shell, so as to reduce the possibility of the crystallized metal salts accumulating on the atomization shell.

[0019] Optionally, the slag cleaning member includes an end ring pipe coaxially arranged on the inner pipe. A liquid pushing disc is coaxially and slidably arranged in the end ring pipe. A liquid pushing screw rod is coaxially arranged on the slag cleaning shaft. The liquid pushing disc is threadedly connected to the liquid pushing screw rod. A guiding block is arranged on the liquid pushing disc. A guiding groove for the guiding block to slide is formed along the axis of the end ring pipe on the inner side wall of the end ring pipe. A salt passing groove opening is formed on the inner side wall of the end ring pipe. The width of the salt passing groove opening along the axis direction of the inner pipe is greater than the width of the liquid pushing disc. A reset compression spring is propped between the liquid pushing disc and the water sealing ring plate.

[0020] By adopting the above technical solution, under the limiting action of the guiding block and the guiding groove, the salt-containing waste water introduced into the end ring pipe will push the liquid pushing disc to slide. The liquid pushing disc makes the liquid pushing screw rod drive the slag cleaning shaft to rotate until the liquid pushing disc slides to the position of the salt passing groove opening. The salt-containing waste water in the end ring pipe will flow into the inner pipe through the salt passing groove opening. During this process, the reset compression spring is continuously compressed.

[0021] Optionally, one end of the atomizing shell facing away from the end plate disc is provided with a slag discharging conical surface, and the slag discharging conical surface inclines downward along the radial direction of the axis of the end plate disc.

[0022] By adopting the above technical solution, the crystallized metal salt scraped by the scraper will be quickly discharged along the inclination direction of the slag discharging conical surface, thereby reducing the possibility of the crystallized metal salt accumulating on the atomizing shell.

[0023] Optionally, a groove is coaxially formed on one side of the dredging ring facing the active ring. An inner ring is coaxially arranged on the active ring. The inner ring is located in the groove and between the ventilation ring groove and the axis of the end plate disc.

[0024] By adopting the above technical solution, the inner ring and the groove on the dredging ring enable the gas to form a bent communication channel in the atomizing shell, and enable the gas to gather from the surrounding of the salt-containing waste water towards the axis direction of the active ring, thereby making the salt-containing waste water flow towards the atomizing holes. At the same time, the inner ring prevents the salt-containing waste water from flowing into the ventilation ring groove through the ventilation holes. When the salt-containing waste water stops being introduced into the inner pipe, the gas can reduce the residue of the salt-containing waste water in the atomizing shell, which is beneficial to reducing the possibility of the salt-containing waste water crystallizing in the atomizing shell.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The dredging component first drives the needle plate to move, so that the dredging needles on the needle plate are inserted into the atomization holes, thereby dredging the metal salts crystallized in the atomization holes. Then, the worker introduces the salt-containing wastewater into the inner pipe and the gas into the space between the outer pipe and the inner pipe. The salt-containing wastewater flows into the atomization shell through the liquid flow holes, and the gas flows into the atomization shell through the ventilation ring grooves. The salt-containing wastewater and the gas are pressurized in the atomization shell and sprayed into the incinerator through the atomization holes. The salt-containing wastewater forms misty small water droplets under the combined action of the atomization holes and the gas. The high temperature in the incinerator will quickly ignite the gas. At the same time, the high temperature in the incinerator and the ignited gas will quickly evaporate and incinerate the atomized salt-containing wastewater small water droplets to form molten metal salts. The molten metal salts will flow along the furnace wall to the quenching tank at the bottom of the furnace. By dredging the atomization holes with the dredging needles before incineration, the situation that the atomization effect of the salt-containing wastewater becomes poor due to the crystallization and blockage of the atomization holes by metal salts is reduced;

[0027] 2. The dredging spring presses the cross bar against the dredging ring through the ejector rod. During the process of the rotating part driving the active ring to rotate, the active ring drives the dredging ring to rotate synchronously. The cross bar abuts against the surface of the dredging ring until the dredging notch on the dredging ring turns above the cross bar. The dredging spring restores its deformation and pushes the cross bar to be stuck in the dredging notch. The ejector rod pushes the dredging needles on the needle plate to insert into the atomization holes on the atomization shell. At this time, the end of the dredging needle is flush with one side of the atomization shell facing away from the end plate disc. The crystals in the atomization holes are discharged. As the active ring continues to rotate, the cross bar gradually slides out along the triangular inclined surface of the dredging notch. During this process, the dredging spring is compressed again, and the needle plate drives the dredging needles to disengage from the atomization holes and reset;

[0028] 3. The sliding part drives the inner driving block to have a tendency to slide. The inner driving block abuts against the inner ring side wall of the active ring during rotation until the inner driving block abuts against the hole-changing block. The inner driving block will slide into the hole-changing groove. During this process, the hole-changing block slides and compresses the hole-changing spring, and the inner driving block compresses the inner driving spring. The hole-changing spring and the inner driving spring are simultaneously compressed and deformed until the liquid passing hole on the inner driving block communicates with the liquid flow hole, and the ventilation hole on the hole-changing block communicates with the ventilation ring groove. At this time, the gas and the salt-containing wastewater flow into the atomization shell at the same time. Description of the Drawings

[0038] Refer to Figure 1 , Figure 2 and Figure 3 , the dredging component 8 includes a driving ring 81 coaxially and rotatably arranged on the end plate disc 1. A dredging ring 83 is coaxially welded on the driving ring 81. A groove 17 is coaxially provided on one side of the dredging ring 83 facing the driving ring 81. An inner ring 18 is coaxially welded on the driving ring 81. The inner ring 18 is located in the groove 17 and between the ventilation ring groove 9 and the axis of the end plate disc 1.

A reset compression spring 157 is propped between the liquid pushing disk 152 and the water sealing ring plate 127.

[0052] Workers feed the salt-containing wastewater into the end ring pipe 151. The liquid pressure in the end ring pipe 151 increases. Under the restrictive action of the guide block 154 and the guide groove 155, the liquid push plate 152 slides along the axial direction of the end ring pipe 151. At the same time, the liquid push plate 152 makes the liquid push screw 153 rotate. The liquid push screw 153 drives the slag cleaning shaft 13 to rotate synchronously. The rotating slag cleaning shaft 13 drives the scraper 14 to scrape off the crystallized metal salts accumulated on the atomizing shell 4.

[0053] Until the liquid push plate 152 slides to the salt passage opening 156, the salt-containing wastewater in the end ring pipe 151 will flow into the inner pipe 3 from the salt passage opening 156, increasing the liquid pressure in the inner pipe 3. During this process, the return compression spring 157 is continuously compressed until the active conical ring 123 gradually separates from the water sealing ring plate 127, and the driving compression spring 126 is continuously compressed. The salt-containing wastewater flows into the inner ring 18 between the water sealing ring plate 127 and the end plate disk 1 through the inner ring 18 holes of the water sealing ring plate 127.

[0054] At the same time, the active conical ring 123 drives the driven conical ring 122 to move synchronously through the driving pipe 121. The driven conical ring 122 pushes the inner driving rod 124. Under the action of the conical surface of the driven conical ring 122, the inner driving rod 124 drives the inner driving block 111 to squeeze the inner driving compression spring 113. As the active ring 81 drives the hole-changing groove 822 to communicate with the inner driving groove 112, the inner driving block 111 slides onto the hole-changing groove 822 and pushes the hole-changing block 821. At this time, the hole-changing compression spring 823 and the inner driving compression spring 113 are simultaneously compressed and deformed.

[0055] Until the liquid passage hole 114 on the inner driving block 111 communicates with the liquid flowing hole 10, and the air vent hole 826 on the hole-changing block 821 communicates with the air vent ring groove 9. At this time, the salt-containing wastewater in the inner pipe 3 flows into the atomizing shell 4 from the liquid flowing hole 10 and the liquid passage hole 114. The gas in the outer pipe 2 flows into the atomizing shell 4 from the air vent ring groove 9 and the air vent hole 826. At the same time, under the action of the inner ring 18, the gas forms a bent flow channel in the atomizing shell 4, and at the same time, the gas squeezes the salt-containing wastewater from the surroundings of the salt-containing wastewater towards the axis direction of the active ring 81.

[0056] The gas drives the salt-containing wastewater to be pressurized in the atomizing shell 4 and is sprayed into the incinerator through the atomizing holes 5. In this way, the salt-containing wastewater forms mist-like small water droplets in the incinerator. The high temperature in the incinerator will quickly ignite the gas ejected from the atomizing holes 5. At the same time, the high temperature and the ignited gas in the incinerator will quickly evaporate and burn the atomized salt-containing wastewater small water droplets to form molten metal salts. The molten metal salts will flow along the furnace wall to the quenching tank at the bottom of the furnace.

[0057] The implementation principle of an atomizing liquid incineration device for a saline wastewater pyrolysis device in an embodiment of the present application is as follows: Workers fill a large amount of gas into the outer tube 2, and the gas flows along the direction of the ventilation ring groove 9, the rotation hole 825, and the exhaust hole 824. The gas flowing out of the exhaust hole 824 is ignited by the high temperature in the incinerator. At the same time, the gas discharged from the exhaust hole 824 and the ignited gas jointly push the active ring 81 to rotate around the axis of the end plate disc 1.

[0058] The active ring 81 drives the dredging ring 83 to rotate synchronously. The dredging compression spring 85 presses the cross bar 86 against the dredging ring 83 through the ejector rod 84. As the dredging ring 83 rotates continuously, the cross bar 86 slides relative to the surface of the dredging ring 83 until the dredging notch 87 on the dredging ring 83 turns above the cross bar 86. The dredging compression spring 85 restores its deformation and pushes the cross bar 86 to be stuck on the dredging notch 87.

[0059] The ejector rod 84 pushes the dredging needle 7 on the needle plate 6 into the atomizing hole 5 on the atomizing shell 4. The crystallized metal salt in the atomizing hole 5 is pushed out by the dredging needle 7. At the same time, the end of the dredging needle 7 is flush with the side of the atomizing shell 4 facing away from the end plate disc 1. As the active ring 81 continues to rotate, the inclined surface on the dredging notch 87 gradually pushes the cross bar 86, and the cross bar 86 drives the ejector rod 84 to compress the dredging compression spring 85. The dredging compression spring 85 is compressed and deformed, and the needle plate 6 drives the dredging needle 7 to disengage from the atomizing hole 5 and reset.

[0060] Workers introduce saline wastewater into the end ring pipe 151. The liquid pressure in the end ring pipe 151 increases. Under the limiting action of the guiding block 154 and the guiding groove 155, the liquid pushing disc 152 slides along the axis direction of the end ring pipe 151. At the same time, the liquid pushing disc 152 makes the liquid pushing screw rod 153 rotate, and the liquid pushing screw rod 153 drives the slag cleaning shaft 13 to rotate synchronously. The rotating slag cleaning shaft 13 drives the scraper 14 to scrape off the crystallized metal salt accumulated on the atomizing shell 4.

[0061] Until the liquid pushing disc 152 slides to the salt passing groove opening 156, the saline wastewater in the end ring pipe 151 will flow into the inner tube 3 through the salt passing groove opening 156, increasing the liquid pressure in the inner tube 3. During this process, the reset compression spring 157 is continuously compressed until the active conical ring 123 gradually separates from the water sealing ring plate 127, and the driving compression spring 126 is continuously compressed. The saline wastewater flows into the inner ring 18 between the water sealing ring plate 127 and the end plate disc 1 through the inner ring 18 holes of the water sealing ring plate 127.

[0062] Meanwhile, the driving cone ring 123 drives the driven cone ring 122 to move synchronously through the driving pipe 121. The driven cone ring 122 drives the inner driving rod 124. Under the action of the conical surface of the driven cone ring 122, the inner driving rod 124 drives the inner driving block 111 to extrude the inner driving compression spring 113. When the driving ring 81 drives the hole-changing groove 822 to communicate with the inner driving groove 112, the inner driving block 111 slides onto the hole-changing groove 822 and pushes the hole-changing block 821. At this time, the hole-changing compression spring 823 and the inner driving compression spring 113 are simultaneously compressed and deformed.

[0063] Until the liquid through-hole 114 on the inner driving block 111 communicates with the liquid flow hole 10, and the gas vent hole 826 on the hole-changing block 821 communicates with the gas vent ring groove 9. At this time, the salt-containing wastewater in the inner pipe 3 flows from the liquid flow hole 10 and the liquid through-hole 114 into the atomization shell 4, and the gas in the outer pipe 2 flows into the atomization shell 4 from the gas vent ring groove 9 and the gas vent hole 826. Meanwhile, under the action of the inner ring 18, the gas forms a bent flow channel in the atomization shell 4, and at the same time, the gas squeezes the salt-containing wastewater from the periphery of the salt-containing wastewater towards the axis direction of the driving ring 81.

[0064] The gas drives the salt-containing wastewater to be pressurized in the atomization shell 4 and is sprayed into the incinerator through the atomization holes 5, so that the salt-containing wastewater forms misty small water droplets in the incinerator. The high temperature in the incinerator will quickly ignite the gas ejected from the atomization holes 5. At the same time, the high temperature and the ignited gas in the incinerator will quickly evaporate and burn the atomized salt-containing wastewater small water droplets to form molten metal salts, and the molten metal salts will flow along the furnace wall to the quenching tank at the bottom of the furnace.

[0065] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
