Description

Technical Field

[0001] This application relates to the technical field of incinerators for saline waste liquid, and in particular to an intelligent high-salt waste liquid incinerator. Background Art

[0002] Saline wastewater mainly comes from chemical plants, the collection and processing of oil and 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. The characteristics of the waste liquid incineration technology are: efficiently, in large quantities, and at low cost, treating saline organic waste liquids with different concentrations.

[0003] The waste liquid incineration technology is to quantitatively spray saline wastewater into the incinerator through an atomizer. After atomization, the wastewater vaporizes at a high temperature (usually 800°C to 1200°C). The alkali metal salts in the wastewater are dispersed in the flue gas in the form of 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. 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] Since the salt content of the saline wastewater treated by the incinerator each time may be different, the water content of the saline wastewater after single atomization is also different. During the process of burning saline wastewater, the main purpose is to vaporize the water in the atomized saline wastewater. Therefore, at the working temperature of the high-temperature incinerator, the actual fuel amount required for vaporizing the water in the saline wastewater each time is different.

[0005] In the traditional technology, the fuel amount for single combustion is usually constant. When the salt content of the saline wastewater is relatively high, the residual heat of single fuel combustion will cause the temperature of the incinerator to rise, which will result in waste of fuel and then lead to a relatively high treatment cost of saline wastewater, having deficiencies. Summary of the Invention

[0006] In order to improve the problem of relatively high cost of traditional treatment of saline wastewater, this application provides an intelligent high-salt waste liquid incinerator.

[0007] An intelligent high-salt waste liquid incinerator provided by this application adopts the following technical solutions:

[0008] An intelligent high-salt waste liquid incinerator, comprising a furnace body, a wake pipe and an atomization mechanism. A salt guide port is provided at the bottom of the furnace body. The wake pipe is communicated with the bottom of the furnace body. A temperature sensor, an air inlet pipe, a fuel pipe and a chamber igniter are arranged on the furnace body. Both the air inlet pipe and the fuel pipe pass through the inner and outer side walls of the furnace body. A fuel valve is arranged on the fuel pipe outside the furnace body. The temperature sensor, the fuel valve and the chamber igniter are all electrically connected to a control system. The atomization mechanism includes a fixed bracket, an atomization head and a liquid inlet pipe. The fixed bracket is arranged inside the furnace body. The atomization head is arranged on the fixed bracket. The liquid inlet pipe passes through the inner and outer side walls of the furnace body and is communicated with the atomization head. The atomization head is used for atomizing the salt-containing waste water. A liquid inlet valve and a densitometer are arranged on the liquid inlet pipe outside the furnace body. The liquid inlet valve and the densitometer are both electrically connected to the control system.

[0009] By adopting the above technical solution, the air inlet pipe conveys a large amount of air into the furnace body. The temperature sensor constantly feeds back the temperature inside the furnace body. When the salt-containing waste water flows through the densitometer, the densitometer feeds back the salt content of the salt-containing waste water to the control system. The control system controls the flow rate of the salt-containing waste water in the liquid inlet pipe through the liquid inlet valve, and at the same time controls the gas delivery volume of the fuel pipe through the fuel valve. Under the action of the atomization head, the salt-containing waste water is atomized in the furnace body and mixed with the fuel and air. Initially, the chamber igniter is required to ignite the fuel, and subsequently, it can be ignited relying on the high temperature inside the furnace body, so that the water is quickly vaporized, thereby achieving the effect of accurately controlling the fuel usage amount and reducing the treatment cost of the salt-containing waste water.

[0010] Optionally, the atomization head includes a top cover plate and a bottom cover plate. A partition is arranged between the top cover plate and the bottom cover plate. The inside of the top cover plate is hollow and open towards the side of the partition. The inside of the bottom cover plate is hollow and open towards the side of the partition. A plurality of atomization holes are formed in the top cover plate. The liquid inlet pipe is communicated with the top cover plate. A needle plate is slidably arranged on the bottom cover plate. A compression spring is propped between the needle plate and the partition. A support ring is arranged on the bottom cover plate. The compression spring presses the needle plate against the support ring. A plurality of cleaning needles are arranged on the needle plate. The cleaning needles slidably pass through the partition. The cleaning needles correspond to the atomization holes one by one. The cleaning needles are used for plugging and matching with the atomization holes. When the cleaning needles are completely inserted into the atomization holes, the ends of the cleaning needles facing away from the needle plate are flush with the surface of the end of the top cover plate facing away from the bottom cover plate. A sliding member for driving the needle plate to slide is arranged on the bottom cover plate. A scraping plate is rotatably arranged on the top cover plate. A rotating member for driving the scraping plate to rotate is arranged on the top cover plate.

[0011] By adopting the above technical solution, the liquid inlet pipe conveys the saline wastewater into the top cover plate and sprays it out through the atomization holes, thereby atomizing the saline wastewater. The high temperature in the furnace body will cause some of the saline wastewater to crystallize at the atomization holes. At this time, the sliding member drives the needle plate to slide, and the needle plate drives the cleaning needle to slide and insert into the atomization holes, thereby pushing the salt crystallized in the atomization holes onto the top cover plate. Then, the rotating member drives the salt scraping plate to rotate, and the rotating salt scraping plate scrapes the crystallized salt on the top cover plate to the inner bottom of the furnace body, thereby realizing the function of dredging the atomization holes, reducing the possibility of the atomization holes on the top cover plate being blocked, and being beneficial to reducing the maintenance cost.

[0012] Optionally, a shaft tube is arranged between the top cover plate and the bottom cover plate. The shaft tube passes through the partition plate, and the needle plate is slidably sleeved on the shaft tube. The rotating member includes a bottom combustion tube arranged on the bottom cover plate and coaxial with the shaft tube. The bottom combustion tube is communicated with the fuel tube. A driving cylinder is coaxially and rotatably arranged in the shaft tube. The driving cylinder is communicated with the bottom combustion tube and rotatably passes through the top cover plate. The salt scraping plate is arranged on the driving cylinder. The length direction of the salt scraping plate is arranged along the radial direction of the axis of the driving cylinder. A material passing groove communicated with the driving cylinder is formed on the salt scraping plate. A plurality of combustion holes communicated with the material passing groove are formed on the salt scraping plate along its length direction. The axis of the combustion hole is perpendicular to the axis of the driving cylinder.

[0013] By adopting the above technical solution, the fuel flows from the fuel tube into the bottom combustion tube, then from the bottom combustion tube into the driving cylinder, then from the driving cylinder into the material passing groove, and finally quickly flows out from the combustion holes and is ignited by the high temperature in the furnace body. The reaction force of the fuel quickly flowing out of the combustion holes and the thrust of the fuel combustion cause the salt scraping plate to rotate around the driving cylinder, thereby realizing the function of the salt scraping plate scraping the crystallized salt on the top cover plate. At the same time, the atomized saline wastewater sprayed out from the atomization holes on the top cover plate will be quickly vaporized by the burning fuel, thereby improving the treatment effect on the saline wastewater.

[0014] Optionally, the sliding member includes a plate inner igniter arranged in the bottom cover plate and electrically connected to the control system. A sleeve is coaxially and rotatably arranged outside the shaft tube. The driving cylinder, the shaft tube and the sleeve are jointly provided with fuel holes along the radial direction of the axis of the driving cylinder. A one-way valve for communicating with the fuel hole is arranged on the sleeve. An exhaust groove opening is formed between the inner and outer side walls of the bottom cover plate. An angle member for driving the sleeve to rotate is arranged on the top cover plate.

[0015] By adopting the above technical solution, the angle piece drives the sleeve to rotate, so that the fuel holes on the sleeve communicate with the fuel holes on the shaft tube. When the fuel holes on the rotating drive cylinder communicate with the fuel holes on the shaft tube, the fuel in the drive cylinder will flow into the bottom cover plate through the fuel holes and the one-way valve under the action of pressure. Then, the control system starts the igniter in the plate, and the igniter in the plate quickly ignites the fuel in the bottom cover plate. The expanded gas in the bottom cover plate pushes the needle plate to slide and compress the compression spring until the cleaning needle on the needle plate completely inserts into the atomization hole. At this time, the expanded gas between the needle plate and the bottom cover plate will quickly discharge from the exhaust slot. Then, the compression spring restores its deformation and pushes the needle plate to reset, so as to achieve the effect of pushing the needle plate.

[0016] Optionally, the sleeve rotates through the partition plate, the needle plate is slidably sleeved on the sleeve, the angle piece includes a reversing box arranged on the partition plate, a liquid chamber with a C-shaped cross-section is opened inside the reversing box, one end of the sleeve facing the reversing box rotates into the reversing box, the liquid inlet pipe includes a first unit pipe and a second unit pipe, a three-way pipe is connected between the first unit pipe and the second unit pipe, liquid inlet valves are arranged on both the first unit pipe and the second unit pipe, the first unit pipe communicates with one end of the C-shaped liquid chamber of the reversing box, the second unit pipe communicates with the other end of the C-shaped liquid chamber of the reversing box, a driving plate is arranged on the sleeve in the liquid chamber, limiting blocks are arranged between the driving plate and the first unit pipe and between the driving plate and the second unit pipe, the limiting blocks are arranged on the liquid chamber of the reversing box, and a liquid flow slot is opened between the inner and outer side walls of the reversing box between the two limiting blocks.

[0017] By adopting the above technical solution, when it is necessary to rotate the sleeve, the control system closes the liquid inlet valve on the first unit pipe and opens the liquid inlet valve on the second unit pipe. The salt-containing waste water in the second unit pipe flows into the liquid chamber and pushes the driving plate. The driving plate rotates around the axis of the sleeve until the driving plate abuts against the limiting block close to the first unit side. At this time, the fuel holes on the sleeve communicate with the fuel holes on the shaft tube, and the salt-containing waste water in the reversing box will flow into the top cover plate through the liquid flow slot, so as to achieve the effect of driving the sleeve to rotate.

[0018] Optionally, an inner tube is coaxially arranged in the drive cylinder. There is a gap between the circumferential outer side wall of the inner tube and the circumferential inner side wall of the drive cylinder. The inner tube is rotationally matched with the bottom combustion tube. An end tube joint communicated with the inner tube is arranged at the end of the bottom combustion tube. The air inlet pipe is communicated with the end tube joint. A blower plate is arranged on the drive cylinder. An air duct slot communicated with the inner tube is opened on the blower plate. A plurality of air outlet holes communicated with the air duct slot are opened along the length direction of the blower plate.

[0019] By adopting the above technical solution, the air in the intake pipe flows in the order of the end pipe joint, the inner pipe, the air duct groove and the air outlet hole, so that the air is quickly ejected from the top cover plate and is quickly and fully mixed with the atomized salt-containing wastewater on the top cover plate, further improving the atomization effect of the salt-containing wastewater and facilitating the rapid vaporization of the salt-containing wastewater.

[0020] Optionally, a connecting rod is arranged on the side of the needle plate facing away from the cleaning needle. The connecting rod slidably passes through the bottom cover plate. An impact plate is arranged on the connecting rod. A collision ring is arranged on the fixed bracket. When the cleaning needle is completely inserted into the atomization hole, the impact plate impacts on the collision ring.

[0021] By adopting the above technical solution, when the cleaning needle is completely inserted into the atomization hole, the needle plate drives the impact plate to impact the collision ring through the connecting rod, so that the fixed bracket vibrates. The fixed bracket will transmit the vibration to the furnace body and the wake pipe, and part of the metal salt liquefied or solidified on the wake pipe will be shaken off to the inner bottom of the furnace body and discharged through the salt guide port, thereby reducing the adhesion amount of the metal salt on the wake pipe and facilitating the reduction of the difficulty for workers to clean the metal salt and the side wall.

[0022] Optionally, a flow guide plate is arranged at the connection between the furnace body and the wake pipe.

[0023] By adopting the above technical solution, it is beneficial to reduce the possibility of a large amount of metal salt being discharged through the wake pipe along with the air flow.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The intake pipe conveys a large amount of air into the furnace body. The temperature sensor continuously feedbacks the temperature in the furnace body. When the salt-containing wastewater flows through the densitometer, the densitometer feedbacks the salt content of the salt-containing wastewater to the control system. The control system controls the flow rate of the salt-containing wastewater in the liquid inlet pipe through the liquid inlet valve, and at the same time controls the gas delivery amount of the fuel pipe through the fuel valve. Under the action of the atomizing head, the salt-containing wastewater is atomized in the furnace body and mixed with the fuel and air. Initially, the chamber igniter is required to ignite the fuel, and subsequently, it can be ignited relying on the high temperature in the furnace body, so that the water is quickly vaporized, thereby achieving the effect of accurately controlling the fuel usage amount and reducing the treatment cost of the salt-containing wastewater;

[0026] 2. The liquid inlet pipe conveys the saline wastewater into the top cover plate and sprays it out through the atomization holes, thereby atomizing the saline wastewater. The high temperature inside the furnace body will cause some of the saline wastewater to crystallize at the atomization holes. At this time, the sliding part drives the needle plate to slide, and the needle plate drives the cleaning needle to slide and insert into the atomization holes, thereby pushing the salt crystallized in the atomization holes onto the top cover plate. Then, the rotating part drives the salt scraping plate to rotate, and the rotating salt scraping plate scrapes the crystallized salt on the top cover plate to the inner bottom of the furnace body, thereby realizing the function of dredging the atomization holes, reducing the possibility of the atomization holes on the top cover plate being blocked, and being beneficial to reducing the maintenance cost;

[0027] 3. The angle part drives the sleeve to rotate, so that the fuel holes on the sleeve are communicated with the fuel holes on the shaft pipe. When the fuel holes on the rotating driving cylinder are communicated with the fuel holes on the shaft pipe, the fuel in the driving cylinder will flow into the bottom cover plate through the fuel holes and the one-way valve under the action of pressure. Then, the control system starts the igniter in the plate, and the igniter in the plate quickly ignites the fuel in the bottom cover plate. The expanded gas in the bottom cover plate pushes the needle plate to slide and compresses the compression spring until the cleaning needle on the needle plate completely inserts into the atomization holes. At this time, the expanded gas between the needle plate and the bottom cover plate will be quickly discharged from the exhaust slot. Then, the compression spring resumes deformation and pushes the needle plate to reset, thereby realizing the effect of pushing the needle plate. Description of the Drawings

[0035] An embodiment of this application discloses an intelligent high-salt waste liquid incinerator.

[0036] Referring to Figure 1 , an intelligent high-salt waste liquid incinerator includes a furnace body 1, a wake pipe 2, and an atomization mechanism 3. A salt guide port 4 is provided at the bottom of the furnace body 1, and the wake pipe 2 communicates with the bottom of the furnace body 1.

[0037] Referring to Figure 1 , Figure 2 and Figure 3 , temperature sensors 5, an air inlet pipe 6, and a fuel pipe 7 are arranged on the furnace body 1. A chamber igniter 8 is bolted to the top of the furnace body 1. Both the air inlet pipe 6 and the fuel pipe 7 pass through the inner and outer side walls of the furnace body 1. A fuel valve 9 is bolted to the fuel pipe 7 outside the furnace body 1. The temperature sensors 5, the fuel valve 9, and the chamber igniter 8 are all electrically connected to a control system.

[0038] Referring to Figure 2 , Figure 3 and Figure 4, the atomization mechanism 3 includes a fixed bracket 31, an atomizing head 32, and a liquid inlet pipe 33. The fixed bracket 31 is welded inside the furnace body 1, the atomizing head 32 is bolted to the fixed bracket 31, the liquid inlet pipe 33 passes through the inner and outer side walls of the furnace body 1 and communicates with the atomizing head 32. The atomizing head 32 is used for atomizing the saline wastewater. A liquid inlet valve 34 and a densitometer 35 are bolted to the liquid inlet pipe 33 outside the furnace body 1, and both the liquid inlet valve 34 and the densitometer 35 are electrically connected to the control system.

[0039] Refer to Figure 4 and Figure 5 , the atomizing head 32 includes a top cover plate 321 and a bottom cover plate 322 arranged coaxially. A partition plate 323 is welded between the top cover plate 321 and the bottom cover plate 322. The inside of the top cover plate 321 is hollow and open towards the partition plate 323. The inside of the bottom cover plate 322 is hollow and open towards the partition plate 323. A number of atomizing holes 324 are formed in the top cover plate 321. The liquid inlet pipe 33 communicates with the top cover plate 321. A needle plate 325 is arranged to slide vertically coaxially inside the bottom cover plate 322.

[0040] Refer to Figure 4 , a compression spring 326 is propped between the needle plate 325 and the partition plate 323. The compression spring 326 is made of a high-temperature resistant material. A support ring 327 is integrally formed coaxially inside the bottom cover plate 322. The compression spring 326 presses the needle plate 325 against the support ring 327. A number of cleaning needles 328 are welded to the needle plate 325, and the cleaning needles 328 slide through the partition plate 323.

[0041] Refer to Figure 4 and Figure 5 , the cleaning needles 328 correspond to the atomizing holes 324 one by one. The cleaning needles 328 are used for plugging and matching with the atomizing holes 324. A retaining ring 23 is integrally formed on the side of the partition plate 323 facing the needle plate 325. When the cleaning needles 328 are completely inserted into the atomizing holes 324, the needle plate 325 impacts on the retaining ring 23. At the same time, the end of the cleaning needle 328 facing away from the needle plate 325 is flush with the surface of the end of the top cover plate 321 facing away from the bottom cover plate 322.

[0042] Refer to Figure 4 and Figure 5 , a shaft tube 12 is welded between the top cover plate 321 and the bottom cover plate 322. The shaft tube 12 passes through the partition plate 323. The needle plate 325 is slidably sleeved on the shaft tube 12. A sliding member 10 for driving the needle plate 325 to slide is arranged on the bottom cover plate 322. A salt scraping plate 329 is rotatably arranged on the top cover plate 321. A rotating member 11 for driving the salt scraping plate 329 to rotate is arranged on the top cover plate 321.

[0043] After the saline wastewater in the liquid inlet pipe 33 flows through the densitometer 35, the densitometer 35 feeds back the salt content of the saline wastewater to the control system. The control system controls the flow rate of the saline wastewater in the liquid inlet pipe 33 by controlling the liquid inlet valve 34. The saline wastewater flowing into the top cover plate 321 is ejected from the atomization holes 324, atomizing the saline wastewater. At the same time, the control system controls the fuel quantity delivered by the fuel pipe 7 to the furnace body 1 through the fuel valve 9.

[0044] The initial control system starts the chamber igniter 8, and the fuel in the furnace body 1 is ignited. The subsequent fuel entering the furnace body 1 will be ignited by the high temperature in the furnace body 1, thereby increasing the temperature in the furnace body 1. The atomized saline wastewater will quickly vaporize under the action of the high temperature in the furnace body 1. The tail gas will be discharged through the wake pipe 2, and the molten salt will adhere to the inner side wall of the furnace body 1 and flow to the salt guide port 4 under the action of gravity.

[0045] Refer to Figure 4 , the rotating member 11 includes a bottom combustion pipe 111 welded to the bottom of the bottom cover plate 322 and coaxial with the shaft pipe 12. The bottom combustion pipe 111 is communicated with the fuel pipe 7. A driving cylinder 112 is rotatably connected coaxially in the shaft pipe 12. The bottom of the driving cylinder 112 is communicated with the bottom combustion pipe 111. The top of the driving cylinder 112 rotates through the top cover plate 321. The salt scraping plate 329 is welded to the driving cylinder 112.

[0046] Refer to Figure 4 , the length direction of the salt scraping plate 329 is arranged along the radial direction of the axis of the driving cylinder 112. A material passing groove 113 communicated with the driving cylinder 112 is formed on the salt scraping plate 329. A plurality of combustion holes 114 communicated with the material passing groove 113 are formed along the length direction of the salt scraping plate 329. The combustion holes 114 are horizontally arranged, and the axis of the combustion holes 114 is perpendicular to the axis of the driving cylinder 112.

[0047] Refer to Figure 4 and Figure 5 , an inner pipe 14 is coaxially welded in the driving cylinder 112. There is a gap between the circumferential outer side wall of the inner pipe 14 and the circumferential inner side wall of the driving cylinder 112. The bottom of the inner pipe 14 is rotationally matched with the bottom combustion pipe 111. An end pipe joint 15 communicated with the inner pipe 14 is welded to the end of the bottom combustion pipe 111.

[0048] Refer to Figure 3 and Figure 4 , the intake pipe 6 is communicated with the end pipe joint 15. A blower plate 16 is welded to the driving cylinder 112. An air duct groove 17 communicated with the inner pipe 14 is formed on the blower plate 16. A plurality of air outlet holes 18 communicated with the air duct groove 17 are formed along the length direction of the blower plate 16. The axis of the air outlet holes 18 is parallel to the axis of the driving cylinder 112.

[0049] Fuel flows into the bottom combustion pipe 111 from the fuel pipe 7, then into the driving cylinder 112 from the bottom combustion pipe 111. The fuel in the driving cylinder 112 flows into the material passing groove 113, and finally quickly flows out through the combustion holes 114 and is ignited by the high temperature inside the furnace body 1. The reaction force of the fuel quickly flowing out of the combustion holes 114 and the thrust of the fuel combustion cause the salt scraping plate 329 to rotate around the driving cylinder 112, and the driving cylinder 112 drives the inner pipe 14 to rotate synchronously.

[0050] The air in the air inlet pipe 6 flows from the end pipe joint 15 to the inner pipe 14, then from the inner pipe 14 to the air duct groove 17, and finally quickly discharges from the air outlet holes 18. At this time, the salt-containing waste water is quickly ejected from the atomization holes 324, and the air blowing plate 16 rotates continuously around the driving cylinder 112, so that the atomized salt-containing waste water ejected from the atomization holes 324 quickly mixes with the air. The fuel burning in the combustion holes 114 on the salt scraping plate 329 will quickly vaporize the mixed atomized salt-containing waste water, and the vaporized water finally discharges from the wake pipe 2.

[0051] Refer to Figure 4 , the sliding member 10 includes a disk ignition device 101 bolted inside the bottom cover plate 322 and electrically connected to the control system. A sleeve 102 is coaxially and rotatably sleeved outside the shaft pipe 12. The driving cylinder 112, the shaft pipe 12 and the sleeve 102 are jointly provided with fuel holes 103 in the radial direction along the axis of the driving cylinder 112. A one-way valve 104 for communicating with the fuel hole 103 is bolted on the sleeve 102. An exhaust groove opening 105 is provided between the inner and outer side walls of the bottom cover plate 322, and an angle member 13 for driving the sleeve 102 to rotate is arranged on the top cover plate 321.

[0052] Refer to Figure 4 and Figure 5 , the sleeve 102 rotates through the partition plate 323, and the needle plate 325 is slidably sleeved on the sleeve 102. The angle member 13 includes a reversing box 131 welded on the partition plate 323. The inside of the reversing box 131 is provided with a liquid chamber 132 with a C-shaped cross-section. One side of the liquid chamber 132 facing the partition plate 323 is open, and one end of the sleeve 102 facing the reversing box 131 rotates into the reversing box 131.

[0053] Refer to Figure 2 , Figure 4 and Figure 5 , the liquid inlet pipe 33 includes a first unit pipe 331 and a second unit pipe 332. A three-way pipe 333 is connected between the first unit pipe 331 and the second unit pipe 332. Liquid inlet valves 34 are bolted on both the first unit pipe 331 and the second unit pipe 332. The first unit pipe 331 communicates with one end of the C-shaped liquid chamber 132 of the reversing box 131, and the second unit pipe 332 communicates with the other end of the C-shaped liquid chamber 132 of the reversing box 131.

[0054] Refer to Figure 5, a drive plate 133 is welded to the sleeve 102 in the liquid chamber 132. The circumferential outer sidewall of the drive plate 133 abuts against the inner wall of the liquid chamber 132. Limiting blocks 134 are arranged between the drive plate 133 and the first unit pipe 331 and between the drive plate 133 and the second unit pipe 332. The limiting blocks 134 are welded to the inner wall of the liquid chamber 132 of the commutation box 131. A liquid flow groove 135 is opened between the inner and outer sidewalls of the commutation box 131 between the two limiting blocks 134.

[0055] Referring to Figure 3 and Figure 4 , a flow guiding plate 22 is welded at the connection between the furnace body 1 and the wake pipe 2. A connecting rod 19 is welded to the side of the needle plate 325 facing away from the cleaning needle 328. The connecting rod 19 slides through the bottom cover plate 322. An impact plate 20 is welded to the connecting rod 19. A collision ring 21 is welded to the fixed bracket 31. When the cleaning needle 328 is completely inserted into the atomization hole 324, the impact plate 20 impacts on the collision ring 21.

[0056] The high temperature of the furnace body 1 will cause some salt-containing wastewater to crystallize at the atomization hole 324. At this time, the control system will close the liquid inlet valve 34 on the first unit pipe 331 and open the liquid inlet valve 34 on the second unit pipe 332. The salt-containing wastewater in the second unit pipe 332 flows into the liquid chamber 132 of the commutation box 131 and pushes the drive plate 133. The drive plate 133 rotates around the axis of the sleeve 102 until the drive plate 133 abuts against the limiting block 134 close to the first unit side.

[0057] At this time, the salt-containing wastewater in the commutation box 131 will flow back into the top cover plate 321 through the liquid flow groove 135 again, and the fuel holes 103 on the sleeve 102 will communicate with the fuel holes 103 on the shaft pipe 12. When the fuel holes 103 on the rotating drive cylinder 112 communicate with the fuel holes 103 on the shaft pipe 12, at this time, the fuel in the drive cylinder 112 will flow into the bottom cover plate 322 through the fuel holes 103 and the one-way valve 104 under the action of pressure.

[0058] After that, the control system starts the ignition device 101 in the disk. The ignition device 101 in the disk quickly ignites the fuel in the bottom cover plate 322. The expanded gas in the bottom cover plate 322 will push the needle plate 325 to slide vertically until the needle plate 325 impacts the retaining ring 23. At this time, the cleaning needle 328 on the needle plate 325 is completely inserted into the atomization hole 324, and at the same time, the expanded gas between the needle plate 325 and the bottom cover plate 322 will be quickly discharged through the exhaust groove 105.

[0059] During this process, the compression spring 326 is compressed and deformed continuously. After that, the compression spring 326 will recover its deformation and push the needle plate 325 to press against the support ring 327 again, so as to push out the metal salt crystallized in the atomization hole 324, and the rotating salt scraping plate 329 will scrape off the pushed-out crystal salt to the inner bottom of the furnace body 1.

[0060] While the needle plate 325 impacts the retaining ring 23, the needle plate 325 drives the impact disc 20 to impact the collision ring 21 through the connecting rod 19, thereby causing the fixed bracket 31 to vibrate. The fixed bracket 31 will transmit the vibration to the furnace body 1 and the wake pipe 2. The metal salt liquefied on the inner side wall of the furnace body 1 will quickly flow towards the salt guide port 4. At the same time, part of the metal salt liquefied or solidified on the wake pipe 2 will be shaken off to the inner bottom of the furnace body 1, and finally all will be discharged from the salt guide port 4.

[0061] The implementation principle of an intelligent high-salt waste liquid incinerator according to an embodiment of the present application is as follows: When the salt-containing wastewater in the liquid inlet pipe 33 flows through the densitometer 35, the densitometer 35 feeds back the salt content of the salt-containing wastewater to the control system. The control system controls the flow rate of the salt-containing wastewater in the liquid inlet pipe 33 by controlling the liquid inlet valve 34. The salt-containing wastewater flowing into the top cover plate 321 is ejected from the atomization holes 324 to atomize the salt-containing wastewater. At the same time, the control system controls the fuel quantity conveyed into the furnace body 1 by the fuel pipe 7 through the fuel valve 9.

[0062] The initial control system starts the chamber igniter 8, and the fuel in the furnace body 1 is ignited. The subsequent fuel entering the furnace body 1 will be ignited by the high temperature in the furnace body 1, thereby increasing the temperature in the furnace body 1. The atomized salt-containing wastewater will quickly vaporize under the action of the high temperature in the furnace body 1. The tail gas will be discharged from the wake pipe 2. The molten salt will adhere to the inner side wall of the furnace body 1 and flow to the salt guide port 4 under the action of gravity.

[0063] The fuel flows from the fuel pipe 7 into the bottom combustion pipe 111, then from the bottom combustion pipe 111 into the driving cylinder 112. The fuel in the driving cylinder 112 flows into the material passing groove 113, and finally quickly flows out from the combustion holes 114 and is ignited by the high temperature in the furnace body 1. The reaction force of the fuel quickly flowing out of the combustion holes 114 and the thrust of the fuel combustion cause the scraping plate 329 to rotate around the driving cylinder 112, and the driving cylinder 112 drives the inner pipe 14 to rotate synchronously.

[0064] The air in the air inlet pipe 6 flows from the end pipe joint 15 to the inner pipe 14, then from the inner pipe 14 to the air duct groove 17, and finally quickly discharges from the air outlet holes 18. Since the salt-containing wastewater is quickly ejected from the atomization holes 324 at this time, and the air blowing plate 16 rotates continuously around the driving cylinder 112, the atomized salt-containing wastewater ejected from the atomization holes 324 is quickly mixed with the air. The fuel burning at the combustion holes 114 on the scraping plate 329 will quickly vaporize the mixed atomized salt-containing wastewater, and the vaporized water will finally be discharged from the wake pipe 2.

[0065] The high temperature of the furnace body 1 will cause some salt-containing wastewater to crystallize at the atomizing holes 324. At this time, the control system will close the liquid inlet valve 34 on the first unit pipe 331 and open the liquid inlet valve 34 on the second unit pipe 332. The salt-containing wastewater in the second unit pipe 332 flows into the liquid chamber 132 of the reversing box 131 and pushes the driving plate 133. The driving plate 133 rotates around the axis of the sleeve 102 until the driving plate 133 abuts against the limiting block 134 near the first unit side.

[0066] At this time, the salt-containing wastewater in the reversing box 131 will flow into the top cover plate 321 again through the liquid flow groove opening 135, and the fuel holes 103 on the sleeve 102 will communicate with the fuel holes 103 on the shaft pipe 12. When the fuel holes 103 on the rotating driving cylinder 112 communicate with the fuel holes 103 on the shaft pipe 12, at this time, the fuel in the driving cylinder 112 will flow into the bottom cover plate 322 through the fuel holes 103 and the one-way valve 104 under the action of pressure.

[0067] After that, the control system starts the igniter 101 in the disk. The igniter 101 in the disk quickly ignites the fuel in the bottom cover plate 322. The expanded gas in the bottom cover plate 322 will push the needle plate 325 to slide vertically until the needle plate 325 hits the retaining ring 23. At this time, the cleaning needle 328 on the needle plate 325 is completely inserted into the atomizing hole 324. At the same time, the expanded gas between the needle plate 325 and the bottom cover plate 322 will be quickly discharged through the exhaust groove opening 105.

[0068] In this process, the compression spring 326 is compressed and deformed continuously. After that, the compression spring 326 will recover its deformation and push the needle plate 325 to press against the supporting ring 327 again, so as to push out the metal salt crystallized in the atomizing hole 324. The rotating salt scraping plate 329 will scrape off the pushed-out crystal salt to the inner bottom of the furnace body 1.

[0069] While the needle plate 325 hits the retaining ring 23, the needle plate 325 drives the impact disk 20 to hit the collision ring 21 through the connecting rod 19, so that the fixed support 31 vibrates. The fixed support 31 will transmit the vibration to the furnace body 1 and the wake pipe 2. The metal salt liquefied on the inner side wall of the furnace body 1 will quickly flow to the salt guiding port 4. At the same time, part of the metal salt liquefied or solidified on the wake pipe 2 will be shaken off to the inner bottom of the furnace body 1 and finally discharged from the salt guiding port 4.

[0070] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
