Description

Technical Field

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

[0002] Salt-containing wastewater mainly comes from chemical plants, oil and natural gas collection and processing, etc. This type of wastewater is usually a mixed liquid of organic and inorganic substances, among which the inorganic substances are mainly alkali metal salts, which are very harmful to the environment. Waste liquid incineration technology is the main treatment method for this waste liquid.

[0003] The waste liquid incineration technology is to spray the salt-containing wastewater into the incinerator in a quantitative manner through an atomizer. After atomization, the wastewater is vaporized at high temperature, and the alkali metal salts in the wastewater are dispersed in the flue gas in the form of micron-sized particles. During the flow of flue gas, the alkali metal salts in the micron-sized particles touch the furnace wall and gather into fluid molten salt. The molten salt flows along the furnace wall to the quench tank at the bottom of the furnace and dissolves in the water inside the quench tank.

[0004] Among them, the atomization effect of salt-containing wastewater is proportional to the treatment effect of wastewater, so the atomizing nozzle hole on the atomizer is usually designed to be very small, but the atomizer itself is in the incinerator. When the atomizer stops spraying salt-containing wastewater, the residual high temperature in the incinerator will cause the salt-containing wastewater attached to the atomizing nozzle hole of the atomizer to crystallize, and the crystallized metal salt will block the atomizing nozzle of the atomizer, thereby causing the subsequent spraying effect of the atomizer to deteriorate, which has shortcomings. Summary of the invention

[0005] In order to improve the problem that salt-containing wastewater crystals clog the atomizing nozzle of the atomizer, resulting in poor atomization effect of the salt-containing wastewater, the present application provides an atomizing liquid incineration device for a salt-containing wastewater pyrolysis equipment.

[0006] The present application provides an atomizing liquid incineration device for a pyrolysis device for salt-containing wastewater, which adopts the following technical solution: The venting device of claim 1, wherein the outer tube has an inner tube and an outer tube protruding from the side of the tube and configured to extend the life of the tube. The venting device of claim 1, wherein the outer tube has an inner tube protruding from the side of the tube and configured to extend the life of the tube. The venting device of claim 1, wherein the outer tube has an inner tube protruding from the side of the tube and configured to extend the life of the tube.

[0007] By adopting the above technical scheme, the dredging component first drives the needle plate to move, so that the dredging needle on the needle plate is inserted into the atomization hole, so as to dredge the metal salt crystallized in the atomization hole, and 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 atomization shell from the liquid flow hole, and the gas flows into the atomization shell from the ventilation ring groove. The saline wastewater and the gas will be pressurized in the atomization shell and sprayed into the incinerator from the atomization hole. The saline wastewater forms mist droplets under the joint action of the atomization hole 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 burn the atomized saline wastewater 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. The atomization hole is dredged by the dredging needle before incineration, which reduces the situation where the atomization hole is blocked by metal salt crystals and the atomization effect of the saline wastewater is deteriorated, which is beneficial to improving the incineration effect of the saline wastewater.

In the process of the rotating member driving the active ring to rotate, the active ring drives the dredging ring to rotate synchronously, and 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 push rod pushes the dredging needle on the needle plate to insert into the atomizing hole on the atomizing shell. At this time, the end of the dredging needle is flush with the side of the atomizing shell facing away from the end plate, and the crystals in the atomizing hole are discharged. As the active ring continues to rotate, the cross bar gradually slides out along the triangular inclined surface on the dredging notch. In this process, the dredging compression spring is compressed again, and the needle plate drives the dredging needle to disengage from the atomizing hole and reset.

Since the exhaust hole is arranged obliquely, the gas discharged from the exhaust hole and the ignited gas drive the active ring to rotate around the axis of the end plate disk, so that the active ring drives the dredging ring to rotate synchronously.

[0012] Optionally, the hole changing assembly includes a plurality of inner drive blocks slidably arranged on the end plate disk, the inner drive blocks slide in the radial direction of the axis of the end plate disk, the end plate disk is provided with a plurality of inner drive grooves for the inner drive blocks to slide, the inner drive grooves correspond to the inner drive blocks one-to-one, the inner drive grooves are used to communicate with the hole changing grooves and correspond one-to-one, an inner drive compression spring is supported between the end of the inner drive block facing away from the axis of the end plate disk and the inner drive groove, the inner drive block is provided with a liquid through hole for connecting the liquid flow hole with the inside of the atomization shell, when the liquid through hole is connected with the liquid flow hole, the ventilation hole is connected with the ventilation ring groove, and a sliding part for driving the inner drive block to slide is provided on the end plate disk.

[0013] By adopting the above technical solution, the sliding member drives the inner drive block to have a sliding tendency, and the inner drive block abuts against the inner ring side wall of the active ring during the rotation process until the inner drive block abuts against the hole-changing block, and the inner drive block slides into the hole-changing groove. During this process, the hole-changing block slides and squeezes the hole-changing compression spring, and the inner drive block squeezes the inner drive compression spring. The hole-changing compression spring and the inner drive compression spring are compressed and deformed at the same time until the liquid through hole on the inner drive block is connected with the liquid flow hole, and the ventilation hole on the hole-changing block is connected with the ventilation ring groove. At this time, the gas and salt-containing wastewater flow into the atomization shell at the same time.

[0014] Optionally, the sliding member includes a driving tube that slides coaxially and passes through the end plate disk, a driven cone ring and an active cone ring are coaxially arranged at two ends of the driving tube, the driven cone ring and the active 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 disk, an inner driving rod is arranged on the inner driving block, the inner driving rod abuts against the conical surface of the driven cone ring, the active cone ring is located in the inner tube, a first bracket is arranged on the inner tube, the driving tube slides through the first bracket, a driving compression spring is supported between the first bracket and the active cone ring, a water sealing ring plate is coaxially arranged on the inner tube, and the conical surface of the active cone ring is used to abut against the inner ring of the water sealing ring plate.

[0015] By adopting the above technical solution, the salt-containing wastewater flowing into the inner tube will push the active cone ring, the active cone ring squeezes the driving compression spring and gradually separates from the water sealing ring plate, and the salt-containing wastewater flows in from the inner ring of the water sealing ring plate. At the same time, the active cone ring pushes the driven cone ring to move synchronously through the driving tube, and the driven cone ring pushes the inner drive rod. Under the action of the cone surface of the driven cone ring, the inner drive rod drives the inner drive block to squeeze the inner drive compression spring, thereby achieving the effect of driving the inner drive block to slide.

[0017] By adopting the above technical solution, the slag cleaning member drives the slag cleaning shaft to rotate, and the rotating slag cleaning shaft drives the scraper to scrape off the crystallized metal salt accumulated on the atomizing shell, thereby reducing the possibility of the crystallized metal salt accumulating on the atomizing shell.

[0019] By adopting the above technical scheme, under the limiting effect of the guide block and the guide groove, the salt-containing wastewater entering the end ring tube will push the liquid push plate to slide, and the liquid push plate causes the liquid push screw to drive the slag cleaning shaft to rotate until the liquid push plate slides to the salt-passing groove. The salt-containing wastewater in the end ring tube will flow into the inner tube from the salt-passing groove. During this process, the reset compression spring is continuously compressed.

[0020] Optionally, a slag discharge cone surface is provided at one end of the atomizing shell facing away from the end plate, and the slag discharge cone surface is inclined downward along the radial direction of the axis of the end plate.

[0023] By adopting the above technical solution, the grooves on the inner ring and the dredging ring allow the gas to form a bent connecting channel in the atomizing shell, and the gas is gathered from the surroundings of the saline wastewater to the axial direction of the active ring, so that the saline wastewater flows to the atomizing hole. At the same time, the inner ring prevents the possibility of the saline wastewater flowing into the ventilation ring groove through the vent hole. When the saline wastewater stops entering the inner tube, the gas can reduce the residual saline wastewater in the atomizing shell, which is beneficial to reducing the possibility of the saline wastewater crystallizing in the atomizing shell.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The dredging component first drives the needle plate to move, so that the dredging needle on the needle plate is inserted into the atomization hole, so as to dredge the metal salt crystallized in the atomization hole. 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 atomization shell from the flow hole, and the gas flows into the atomization shell from the ventilation ring groove. The saline wastewater and the gas will be pressurized in the atomization shell and sprayed into the incinerator from the atomization hole. The saline wastewater forms mist droplets under the joint action of the atomization hole 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 burn the atomized saline wastewater droplets to form molten metal salts. The molten metal salts will flow along the furnace wall to the quench tank at the bottom of the furnace. The atomization hole is dredged by the dredging needle before incineration, which reduces the situation where the metal salt crystal blocks the atomization hole and causes the atomization effect of the saline wastewater to deteriorate. 2. The dredging compression spring presses the cross bar against the dredging ring through the push rod. When the rotating member drives the active ring to rotate, the active ring drives the dredging ring to rotate synchronously. The cross bar contacts the surface of the dredging ring until the dredging notch on the dredging ring rotates above the cross bar. The dredging compression spring recovers its deformation and pushes the cross bar to get stuck on the dredging notch. The push rod pushes the dredging needle on the needle plate to insert into the atomizing hole on the atomizing shell. At this time, the end of the dredging needle is flush with the side of the atomizing shell facing away from the end plate. The crystals in the atomizing hole are discharged. As the active ring continues to rotate, the cross bar gradually slides out along the triangular slope on the dredging notch. In this process, the dredging compression spring is compressed again, and the needle plate drives the dredging needle to leave the atomizing hole and reset. 3. The sliding member drives the inner drive block to slip, and the inner drive block abuts against the inner ring side wall of the active ring during the rotation process until the inner drive block abuts against the hole-changing block, and the inner drive block slides into the hole-changing groove. During this process, the hole-changing block slides and squeezes the hole-changing compression spring, and the inner drive block squeezes the inner drive compression spring. The hole-changing compression spring and the inner drive compression spring are compressed and deformed at the same time until the liquid through hole on the inner drive block is connected with the liquid flow hole, and the ventilation hole on the hole-changing block is connected with the ventilation ring groove. At this time, the gas and salt-containing wastewater flow into the atomization shell at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Until the liquid pushing plate 152 slides to the salt passing groove 156, the salt-containing wastewater in the end ring tube 151 will flow into the inner tube 3 through the salt passing groove 156, increasing the liquid pressure in the inner tube 3. During this process, the reset compression spring 157 is continuously compressed until the active cone ring 123 gradually separates from the water sealing ring plate 127, and the driving compression spring 126 is continuously compressed, and the salt-containing wastewater flows from the inner ring 18 hole of the water sealing ring plate 127 into the inner ring 18 between the water sealing ring plate 127 and the end plate disc 1.

[0050] At the same time, the active cone ring 123 pushes the driven cone ring 122 to move synchronously through the driving tube 121, and the driven cone ring 122 pushes the inner drive rod 124. Under the action of the conical surface of the driven cone ring 122, the inner drive rod 124 drives the inner drive block 111 to squeeze the inner drive compression spring 113. As the active ring 81 drives the hole changing groove 822 to connect with the inner drive groove 112, the inner drive 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 drive compression spring 113 are compressed at the same time and deformed.

[0051] Until the liquid through hole 114 on the inner drive block 111 is connected with the liquid flow hole 10, and the vent hole 826 on the hole-changing block 821 is connected with the ventilation ring groove 9, at this time, the salt-containing wastewater in the inner tube 3 flows into the atomizing shell 4 through the liquid flow hole 10 and the liquid through hole 114, and the gas in the outer tube 2 flows into the atomizing shell 4 through the ventilation ring groove 9 and the 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 surrounding of the salt-containing wastewater toward the axial direction of the active ring 81.

[0052] The gas drives the salt-containing wastewater to be pressurized in the atomizing shell 4 and sprayed into the incinerator through the atomizing hole 5, so that the salt-containing wastewater is in the form of mist droplets in the incinerator. The high temperature in the incinerator will quickly ignite the gas sprayed from the atomizing hole 5. At the same time, the high temperature in the incinerator and the ignited gas will quickly evaporate and burn the atomized salt-containing wastewater droplets to form molten metal salts. The molten metal salts will flow along the furnace wall to the quench tank at the bottom of the furnace.

[0053] The implementation principle of the atomizing liquid incineration device for a pyrolysis device for salt-containing wastewater in an embodiment of the present application is as follows: a worker fills a large amount of fuel gas into the outer tube 2, and the fuel gas flows along the ventilation ring groove 9, the rotating hole 825 and the exhaust hole 824. The fuel gas flowing out of the exhaust hole 824 is ignited by the high temperature in the incinerator. At the same time, the fuel gas discharged from the exhaust hole 824 and the ignited fuel gas jointly push the active ring 81 to rotate around the axis of the end plate disk 1.

[0054] The active ring 81 drives the dredging ring 83 to rotate synchronously, and the dredging compression spring 85 presses the cross bar 86 onto the dredging ring 83 through the push rod 84. As the dredging ring 83 continues to rotate, the cross bar 86 slides relative to the surface of the dredging ring 83 until the dredging notch 87 on the dredging ring 83 rotates to above the cross bar 86, and the dredging compression spring 85 restores its deformation and pushes the cross bar 86 to get stuck on the dredging notch 87.

[0055] The push rod 84 pushes the dredging needle 7 on the needle plate 6 to insert into the atomizing hole 5 on the atomizing shell 4, and the crystallized metal salt crystallized 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 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 push 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.

[0056] Workers pass saline wastewater into the end ring pipe 151, and the liquid pressure in the end ring pipe 151 increases. Under the limiting 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 causes the liquid push screw 153 to rotate, and 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 crystalline metal salt accumulated on the atomizing shell 4.

[0057] Until the liquid pushing plate 152 slides to the salt passing groove 156, the salt-containing wastewater in the end ring tube 151 will flow into the inner tube 3 through the salt passing groove 156, increasing the liquid pressure in the inner tube 3. During this process, the reset compression spring 157 is continuously compressed until the active cone ring 123 gradually separates from the water sealing ring plate 127, and the driving compression spring 126 is continuously compressed, and the salt-containing wastewater flows from the inner ring 18 hole of the water sealing ring plate 127 into the inner ring 18 between the water sealing ring plate 127 and the end plate disc 1.

[0058] At the same time, the active cone ring 123 pushes the driven cone ring 122 to move synchronously through the driving tube 121, and the driven cone ring 122 pushes the inner drive rod 124. Under the action of the conical surface of the driven cone ring 122, the inner drive rod 124 drives the inner drive block 111 to squeeze the inner drive compression spring 113. As the active ring 81 drives the hole changing groove 822 to connect with the inner drive groove 112, the inner drive 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 drive compression spring 113 are compressed at the same time and deformed.

[0059] Until the liquid through hole 114 on the inner drive block 111 is connected with the liquid flow hole 10, and the vent hole 826 on the hole-changing block 821 is connected with the ventilation ring groove 9, at this time, the salt-containing wastewater in the inner tube 3 flows into the atomizing shell 4 through the liquid flow hole 10 and the liquid through hole 114, and the gas in the outer tube 2 flows into the atomizing shell 4 through the ventilation ring groove 9 and the 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 surrounding of the salt-containing wastewater toward the axial direction of the active ring 81.

[0060] The gas drives the salt-containing wastewater to be pressurized in the atomizing shell 4 and sprayed into the incinerator through the atomizing hole 5, so that the salt-containing wastewater is in the form of mist droplets in the incinerator. The high temperature in the incinerator will quickly ignite the gas sprayed from the atomizing hole 5. At the same time, the high temperature in the incinerator and the ignited gas will quickly evaporate and burn the atomized salt-containing wastewater droplets to form molten metal salts. The molten metal salts will flow along the furnace wall to the quench tank at the bottom of the furnace.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
