Description

Technical Field

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

[0002] Salt-containing wastewater mainly comes from chemical plants, oil and natural gas collection and processing, etc. This 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. The characteristics of waste liquid incineration technology are: efficient, large-scale and low-cost treatment of salt-containing organic waste liquids of different concentrations.

[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 (usually 800℃ to 1200℃), 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] Since the salt content of the salt-containing wastewater treated by the incinerator may be different each time, the water content of the salt-containing wastewater after a single atomization is also different. The process of burning the salt-containing wastewater is mainly to vaporize the water in the salt-containing wastewater in the atomized state. Therefore, under the working temperature of the high-temperature incinerator, the actual amount of fuel required for vaporizing the water in the salt-containing wastewater at a single time is different.

[0005] In traditional technology, the amount of fuel burned in a single combustion is usually constant. However, when the salt content of the saline wastewater is high, the residual heat from the single fuel combustion will cause the temperature of the incinerator to rise, which will cause fuel waste and lead to high treatment costs for the saline wastewater, which is a disadvantage. Summary of the invention

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

[0007] The intelligent high-salt waste liquid incinerator provided in this application adopts the following technical solution: An intelligent high-salt waste liquid incinerator comprises a furnace body, a tail flow pipe and an atomizing mechanism, wherein a salt guide port is provided at the bottom of the furnace body, the tail flow pipe is connected to the bottom of the furnace body, a temperature sensor, an air intake pipe, a fuel pipe and a chamber igniter are arranged on the furnace body, the air intake pipe and the fuel pipe both 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 atomizing mechanism comprises a fixed bracket, an atomizing head and a liquid inlet pipe, the fixed bracket is arranged in the furnace body, the atomizing 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 connected to the atomizing head, the atomizing head is used to atomize salt-containing wastewater, a liquid inlet valve and a density meter are arranged on the liquid inlet pipe outside the furnace body, and the liquid inlet valve and the density meter are both electrically connected to a control system.

[0008] By adopting the above technical solution, the air inlet pipe transports a large amount of air into the furnace body, and the temperature sensor always feeds back the temperature inside the furnace body. When the saline wastewater flows through the density meter, the density meter 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 through the liquid inlet valve, and controls the gas delivery volume of the fuel pipe through the fuel valve. Under the action of the atomizing head, the saline 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 then it can be ignited by relying on the high temperature in the furnace body to vaporize the water quickly, thereby achieving the effect of accurately controlling the fuel usage, thereby reducing the treatment cost of the saline wastewater.

[0009] Optionally, the atomizer 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 interior of the top cover plate is hollow and open toward one side of the partition, the interior of the bottom cover plate is hollow and open toward one side of the partition, a plurality of atomization holes are provided on the top cover plate, the liquid inlet pipe is connected with the top cover plate, a needle plate is slidably arranged on the bottom cover plate, a compression spring is supported between the needle plate and the partition, a supporting ring is arranged on the bottom cover plate, and the compression spring presses the needle plate against the supporting ring, A plurality of cleaning needles are arranged on the needle plate, and the cleaning needles slide through the partition plate. The cleaning needles correspond to the atomization holes one by one, and are used to be plugged into and cooperate with the atomization holes. When the cleaning needles are fully inserted into the atomization holes, one end of the cleaning needle facing away from the needle plate is flush with the surface of one end of the top cover plate facing away from the bottom cover plate. A sliding part for driving the needle plate to slide is arranged on the bottom cover plate, and a salt scraping plate is rotatably arranged on the top cover plate. A rotating part for driving the salt scraping plate to rotate is arranged on the top cover plate.

[0010] By adopting the above technical scheme, the liquid inlet pipe transports the salt-containing wastewater into the top cover plate and sprays it out from the atomization hole, so that the salt-containing wastewater is atomized, and the high temperature in the furnace body will cause part of the salt-containing wastewater to crystallize at the atomization hole. 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 hole, so as to push the crystallized salt in the atomization hole onto the top cover plate, and then the rotating member drives the salt scraper plate to rotate, and the rotating salt scraper plate scrapes the crystallized salt on the top cover plate to the inner bottom of the furnace body, thereby achieving the effect of unblocking the atomization hole, reducing the possibility of the atomization hole on the top cover plate being blocked, which is beneficial to reducing the maintenance cost.

[0011] Optionally, an axis tube is provided between the top cover plate and the bottom cover plate, the axis tube passes through the partition, the needle plate is slidably sleeved on the axis tube, the rotating member includes a bottom fuel tube provided on the bottom cover plate and coaxial with the axis tube, the bottom fuel tube is connected with the fuel pipe, a driving cylinder is coaxially provided in the axis tube, the driving cylinder is connected with the bottom fuel tube and rotates through the top cover plate, the salt scraper plate is provided on the driving cylinder, the length direction of the salt scraper plate is arranged along the radial direction of the axis of the driving cylinder, a material passing groove connected with the driving cylinder is provided on the salt scraper plate, a plurality of combustion holes connected with the material passing groove are provided on the salt scraper plate along its length direction, and the axis of the combustion hole is perpendicular to the axis of the driving cylinder.

[0012] By adopting the above technical scheme, the fuel flows from the fuel pipe into the bottom combustion pipe, then flows from the bottom combustion pipe into the driving cylinder, and then flows from the driving cylinder into the material trough, and finally flows out quickly from the combustion hole and is ignited by the high temperature in the furnace body. The reaction force of the fuel flowing out of the combustion hole quickly and the thrust of the fuel combustion cause the salt scraper plate to rotate around the driving cylinder, thereby achieving the function of the salt scraper plate to scrape off the crystallized salt on the top cover plate. At the same time, the atomized salt-containing wastewater sprayed from the atomization hole on the top cover plate will be quickly vaporized by the burning fuel, thereby improving the treatment effect of the salt-containing wastewater.

[0014] By adopting the above technical solution, the angle piece drives the sleeve to rotate, so that the fuel hole on the sleeve is connected with the fuel hole on the shaft tube. When the fuel hole on the rotating driving cylinder is connected with the fuel hole on the shaft tube, the fuel in the driving cylinder will flow into the bottom cover plate through the fuel hole and the one-way valve under the action of pressure, and 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, and the expanding gas in the bottom cover plate pushes the needle plate to slide and squeezes the compression spring until the cleaning needle on the needle plate is completely inserted into the atomization hole. At this time, the expanded gas between the needle plate and the bottom cover plate will be quickly discharged from the exhaust groove, and then the compression spring will restore its deformation and push the needle plate to reset, thereby achieving the effect of pushing the needle plate.

[0015] Optionally, the sleeve rotates and passes through the partition, the needle plate is slidably mounted on the sleeve, the angle piece includes a reversing box arranged on the partition, a liquid chamber with a C-shaped cross section is opened inside the reversing box, the sleeve rotates toward one end of the reversing box and penetrates into the reversing box, the liquid inlet pipe includes a first unit tube and a second unit tube, a three-way pipe is connected between the first unit tube and the second unit tube, the liquid inlet valve is arranged on the first unit tube and the second unit tube, the first unit tube is communicated with one end of the C-shaped liquid chamber of the reversing box, and the second unit tube is communicated 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, and limit blocks are arranged between the driving plate and the first unit tube and between the driving plate and the second unit tube, the limit blocks are arranged on the liquid chamber of the reversing box, and a liquid flow groove is opened between the inner and outer side walls of the reversing box between the two limit blocks.

[0016] 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 tube and opens the liquid inlet valve on the second unit tube, and the salt-containing wastewater in the second unit tube flows into the liquid chamber and pushes the driving plate, and the driving plate rotates around the axis of the sleeve until the driving plate abuts against the limit block close to the side of the first unit. At this time, the fuel hole on the sleeve is connected with the fuel hole on the shaft tube, and the salt-containing wastewater in the reversing box will flow into the top cover plate from the liquid flow groove, thereby achieving the effect of driving the sleeve to rotate.

[0017] Optionally, an inner tube is coaxially arranged inside the driving tube, and there is a gap between the circumferential outer wall of the inner tube and the circumferential inner wall of the driving tube.

A blast plate is arranged on the driving tube, and an air duct groove connected to the inner tube is opened on the blast plate. A plurality of air outlet holes connected to the air duct groove are opened on the blast plate along its length direction.

[0018] By adopting the above technical scheme, the air in the air intake pipe flows along the end pipe joint, the inner pipe, the air duct groove and the air outlet in sequence, so that the air is quickly ejected from the top cover plate and quickly and fully mixed with the saline wastewater atomized on the top cover plate, thereby further improving the atomization effect of the saline wastewater and facilitating the rapid vaporization of the saline wastewater.

[0019] Optionally, a connecting rod is provided on the side of the needle plate facing away from the cleaning needle, the connecting rod slides through the bottom cover plate, an impact plate is provided on the connecting rod, and a collision ring is provided on the fixed bracket, and when the cleaning needle is fully inserted into the atomization hole, the impact plate impacts the collision ring.

[0020] By adopting the above technical solution, when the cleaning needle is fully inserted into the atomization hole, the needle plate drives the impact plate to impact the collision ring through the connecting rod, thereby causing the fixed bracket to vibrate. The fixed bracket will transmit the vibration to the furnace body and the tail pipe, and the metal salt that is partially liquefied or solidified on the tail pipe will be shaken to the inner bottom of the furnace body and discharged from the salt guide port, thereby reducing the amount of metal salt attached to the tail pipe, which is conducive to reducing the difficulty of workers in cleaning the metal salt and the side walls.

[0021] Optionally, a guide plate is provided at the connection point between the furnace body and the tail flow pipe.

[0022] The adoption of the above technical solution is helpful to reduce the possibility of a large amount of metal salt being discharged through the tail pipe along with the air flow.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The air inlet pipe delivers a large amount of air to the furnace body, and the temperature sensor always feeds back the temperature inside the furnace body. When the saline wastewater flows through the density meter, the density meter 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 through the liquid inlet valve, and controls the gas delivery volume of the fuel pipe through the fuel valve. Under the action of the atomizing head, the saline 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 then the high temperature in the furnace body can be used to ignite it, so that the water can be quickly vaporized, so as to achieve the effect of accurately controlling the amount of fuel used, thereby reducing the treatment cost of saline wastewater; 2. The liquid inlet pipe transports the salt-containing wastewater into the top cover plate and sprays it out from the atomization hole, thereby atomizing the salt-containing wastewater. The high temperature in the furnace body will cause part of the salt-containing wastewater to crystallize at the atomization hole. 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 hole, thereby pushing the crystallized salt in the atomization hole onto the top cover plate, and 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 achieving the function of unblocking the atomization hole, reducing the possibility of the atomization hole on the top cover plate being blocked, which is conducive to reducing the maintenance cost; 3. The angle piece drives the sleeve to rotate, so that the fuel hole on the sleeve is connected with the fuel hole on the shaft tube. When the fuel hole on the rotating driving cylinder is connected with the fuel hole on the shaft tube, the fuel in the driving cylinder will flow into the bottom cover plate through the fuel hole and the one-way valve under the action of pressure, and 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 squeezes the compression spring until the cleaning needle on the needle plate is completely inserted into the atomization hole. At this time, the expanded gas between the needle plate and the bottom cover plate will be quickly discharged from the exhaust notch, and then the compression spring will restore its deformation and push the needle plate to reset, thereby achieving the effect of pushing the needle plate.

[0053] 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 135, and the fuel hole 103 on the sleeve 102 will be connected with the fuel hole 103 on the shaft tube 12. As the fuel hole 103 on the rotating driving cylinder 112 is connected with the fuel hole 103 on the shaft tube 12, the fuel in the driving cylinder 112 will flow into the bottom cover plate 322 through the fuel hole 103 and the one-way valve 104 under the action of pressure.

[0054] After that, the control system starts the in-disk igniter 101, which quickly ignites the fuel in the bottom cover disk 322. The expanding gas in the bottom cover disk 322 pushes 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 atomization hole 324. At the same time, the expanding gas between the needle plate 325 and the bottom cover disk 322 is quickly discharged from the exhaust slot 105.

[0055] During this process, the compression spring 326 is continuously deformed under pressure, and then the compression spring 326 will restore its deformation and push the needle plate 325 to press against the support ring 327 again, thereby pushing out the metal salt crystallized in the atomization hole 324, and the rotating salt scraper plate 329 will scrape the pushed out crystallized salt to the inner bottom of the furnace body 1.

[0056] While the needle plate 325 hits the baffle ring 23, the needle plate 325 drives the impact plate 20 to hit 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 tail pipe 2, and the metal salt liquefied on the inner wall of the furnace body 1 will quickly flow to the salt guide port 4. At the same time, the metal salt partially liquefied or solidified on the tail pipe 2 will be shaken off to the inner bottom of the furnace body 1 and finally discharged from the salt guide port 4.

[0057] The implementation principle of an intelligent high-salt waste liquid incinerator in an embodiment of the present application is as follows: when the saline wastewater in the liquid inlet pipe 33 flows through the density meter 35, the density meter 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 sprayed out from the atomization hole 324 to atomize the saline wastewater. At the same time, the control system controls the amount of fuel transported into the furnace body 1 by the fuel pipe 7 through the fuel valve 9.

[0058] The initial control system starts the chamber igniter 8, the fuel in the furnace body 1 is ignited, and the fuel subsequently 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, and the atomized salt-containing wastewater will quickly vaporize under the action of the high temperature in the furnace body 1, the exhaust gas will be discharged from the tail pipe 2, and the molten salt will adhere to the inner wall of the furnace body 1 and flow to the salt guide port 4 under the action of gravity.

[0059] The fuel flows from the fuel pipe 7 into the bottom combustion pipe 111, and then flows from the bottom combustion pipe 111 into the driving cylinder 112. The fuel in the driving cylinder 112 flows into the material trough 113, and finally flows out quickly from the combustion hole 114 and is ignited by the high temperature in the furnace body 1. The reaction force of the fuel flowing out of the combustion hole 114 quickly and the thrust of the fuel combustion cause the salt scraper 329 to rotate around the driving cylinder 112, and the driving cylinder 112 drives the inner tube 14 to rotate synchronously.

[0060] 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 is quickly discharged from the air outlet 18. At this time, the salt-containing wastewater is quickly ejected from the atomizing hole 324, and the blast plate 16 continuously rotates around the driving cylinder 112, so that the atomized salt-containing wastewater ejected from the atomizing hole 324 is quickly mixed with the air, and the fuel burned in the combustion hole 114 on the salt scraper plate 329 will quickly vaporize the mixed atomized salt-containing wastewater, and the vaporized water is finally discharged from the tail pipe 2.

[0061] The high temperature of the furnace body 1 will cause part of the 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 tube 331 and open the liquid inlet valve 34 on the second unit tube 332. The salt-containing wastewater in the second unit tube 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 limit block 134 close to the side of the first unit.

[0062] 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 135, and the fuel hole 103 on the sleeve 102 will be connected with the fuel hole 103 on the shaft tube 12. As the fuel hole 103 on the rotating driving cylinder 112 is connected with the fuel hole 103 on the shaft tube 12, the fuel in the driving cylinder 112 will flow into the bottom cover plate 322 through the fuel hole 103 and the one-way valve 104 under the action of pressure.

[0063] After that, the control system starts the in-disk igniter 101, which quickly ignites the fuel in the bottom cover disk 322. The expanding gas in the bottom cover disk 322 pushes 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 atomization hole 324. At the same time, the expanding gas between the needle plate 325 and the bottom cover disk 322 is quickly discharged from the exhaust slot 105.

[0064] During this process, the compression spring 326 is continuously deformed under pressure, and then the compression spring 326 will restore its deformation and push the needle plate 325 to press against the support ring 327 again, thereby pushing out the metal salt crystallized in the atomization hole 324, and the rotating salt scraper plate 329 will scrape the pushed out crystallized salt to the inner bottom of the furnace body 1.

[0065] While the needle plate 325 hits the baffle ring 23, the needle plate 325 drives the impact plate 20 to hit 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 tail pipe 2, and the metal salt liquefied on the inner wall of the furnace body 1 will quickly flow to the salt guide port 4. At the same time, the metal salt partially liquefied or solidified on the tail pipe 2 will be shaken off to the inner bottom of the furnace body 1 and finally discharged from the salt guide port 4.

[0066] 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.
