Description

Technical Field

[0001] The present invention relates to the technical field of waste liquid treatment, in particular to an incineration device and a process for treating salt-containing and chlorine-containing waste liquid. Background Art

[0002] Salt-containing and chlorine-containing waste liquids come from multiple industries such as chemical, pharmaceutical, dye, printing and dyeing, and papermaking. These waste liquids usually contain high concentrations of inorganic salts and organic matter. If they are discharged directly without treatment, they will cause serious pollution to the environment. Therefore, incineration equipment for treating salt-containing and chlorine-containing waste liquids is set up to incinerate the salt-containing and chlorine-containing waste liquids at high temperature, and completely decompose the organic matter and inorganic salts in the waste liquid and convert them into harmless solid residues and gases. This treatment method can effectively avoid the pollution to the environment caused by direct discharge of waste liquids, especially prevent the damage to the water ecosystem.

[0003] After searching, the Chinese patent application number 202222498136.2 discloses an incineration treatment device for high-concentration salt-containing organic waste liquid, including a heat-conducting ceramic plate, which is arranged at the upper end of the incinerator main body, the incinerator main body is fixedly connected to the heat-conducting ceramic plate, the upper end of the heat-conducting ceramic plate is installed with a preheating box, a spray pump is installed on one side of the preheating box, and the spray pump is fixedly connected to the preheating box. The device can preheat the waste liquid inside the preheating box by installing the heat-conducting ceramic plate, thereby enhancing the heat utilization rate of the device and at the same time improving the incineration efficiency of the waste liquid and enhancing the practicality of the device. The installation of hot air flow blades can make it rotate under the action of the hot air flow, and the rotation of the hot air flow blades will drive the atomizing spray pipe to rotate, thereby enhancing the flexibility of the device and allowing all-round spraying inside the device to avoid the atomized waste liquid from not being able to be quickly and fully incinerated, thereby affecting the waste liquid incineration efficiency.

[0004] The above patents still have the following deficiencies: (1) It is not easy to clean the inner wall. After the device burns the waste liquid, the metal salts in the waste liquid are easily attached to the inner wall of the device and produce crystalline solids. If the inner wall is not cleaned for a long time, it will lead to increased corrosion and wear inside the equipment, shortening the service life of the equipment; (2) There is a defect of uneven spraying of waste liquid. The spraying range of the existing device is fixed, which is prone to local overheating or uneven combustion, so that the organic matter and inorganic salts in the waste liquid cannot be burned more fully and thoroughly; (3) There is a defect of easy clogging of the nozzle. After the nozzle sprays the waste liquid, some crystals are easily precipitated on the surface of the nozzle, causing the nozzle to be clogged, affecting the use of the nozzle of the device; (4) There is a defect of easy leakage of waste gas. In the process of discharging crystals in the existing device, some waste gas is easy to leak through the slag discharge port, affecting the environment around the device. Summary of the Invention

[0022] The present application also discloses a burning process for treating salt-containing and chlorine-containing waste liquid, which comprises the following steps:

[0023] S1: waste liquid pretreatment: pretreating the salt-containing and chlorine-containing waste liquid, such as adjusting pH value, removing suspended solids or performing other necessary chemical treatment;

[0024] S2: Waste liquid spraying: The pre-treated waste liquid is input into the injection pipe through a special high-pressure pump, and the waste liquid is sprayed into the interior of the first thermal insulation tank in the form of mist or small droplets using an atomizing nozzle;

[0025] S3: Incineration process: The waste liquid is incinerated by generating a high-temperature flame through the first burner.

At the same time, the inorganic salts melt or precipitate in granular form at high temperature.

[0027] S5: Secondary incineration: The waste gas generated by the incineration of the waste liquid is injected into the interior of the burner through the connecting pipe, and the combustion-supporting gas is injected into the interior of the second thermal insulation tank through the gas pipe and the gas nozzle. The second burner is started to heat the interior of the second thermal insulation tank, so that the organic matter in the waste gas is oxidized and decomposed into carbon dioxide and water vapor, and the chlorine reacts with oxygen to form hydrogen chloride. The ash generated in this process is discharged through the ash discharge port;

[0028] S6: Tail gas treatment: The completely burned exhaust gas is discharged through the exhaust pipe and is purified through cooling, dust removal, desulfurization, denitrification and other treatments. After meeting the emission standards, it is discharged into the atmosphere through the chimney.

[0029] Compared with the prior art, the present invention provides an incineration device for treating salt-containing and chlorine-containing wastewater, which has the following beneficial effects:

[0030] 1. This incineration equipment for treating salt- and chlorine-containing waste liquid uses a servo motor to drive the transmission shaft through a reduction gearbox, so that the scraper scrapes off the crystals on the inner wall of the first insulation tank and pushes these crystals toward the slag discharge port, achieving all-round cleaning of the inner wall. It can completely remove stubborn metal salt crystals and other residues according to actual needs or preset cycles, ensuring that the interior of the first insulation tank always remains clean and flawless, effectively preventing potential corrosion and wear of the equipment by metal salt crystals and residues, and extending the service life of the equipment;

[0031] 2. This incineration equipment for treating salt- and chlorine-containing waste liquid drives the rotation of the first bevel gear through the rotation of the transmission shaft. At the same time, the cooperation between the half gear and the ring gear enables the atomizing nozzle to move back and forth in the first insulation inner tank, ensuring that the waste liquid can be evenly distributed, avoiding local overheating or uneven combustion problems, and allowing the organic matter and inorganic salts in the waste liquid to be burned more fully and thoroughly, significantly improving the incineration efficiency;

[0032] 3. This incineration equipment for treating salt- and chlorine-containing waste liquid uses a pneumatic telescopic rod and a cleaning brush to precisely move the cleaning brush to the bottom of the atomizing nozzle. The rotary power of the drive shaft then allows the cleaning brush to gently rotate to clean the bottom of the atomizing nozzle. This not only achieves the nozzle cleaning function, but also keeps the atomizing nozzle in the best working condition at all times, and ensures the adequacy and efficiency of the incineration process.

[0033] 4. The incineration equipment for treating salt- and chlorine-containing waste liquid continuously pushes the crystals to the slag discharge port through the driving motor and the driving push plate of the rotating shaft. At the same time, the support shell and the baffle plate enable the push plate to tightly seal the slag discharge port during the rotation process, which not only facilitates the smooth discharge of solid waste such as slag and fly ash, but also effectively prevents the leakage of internal gas and avoids the pollution of harmful gases to the environment.

[0054] like Figure 3 As shown, in one embodiment: the liquid incinerator includes a combustion furnace 5 fixed on one side of the top of the base plate 1 and connected to the connecting pipe 10, a first insulation inner liner 17 fixed inside the combustion furnace 5, a first burner 6 installed on one side of the first insulation inner liner 17, and a slag discharge port 4 installed on one side of the bottom end of the combustion furnace 5; the gas incinerator includes a combustion furnace 13 arranged on one side of the top of the base plate 1 and connected to the connecting pipe 10, a second insulation inner liner 19 fixed inside the combustion furnace 13, an exhaust pipe 14 installed on one side of the combustion furnace 13, an ash discharge port 2 installed at the bottom end of the combustion furnace 13, a second burner 12 installed at the top end of the second insulation inner liner 19, a gas pipeline 11 fixed on the outside of the combustion furnace 13, and a gas nozzle 18 installed inside the second insulation inner liner 19 and connected to the gas pipeline 11, and a discharge structure 3 is provided inside the slag discharge port 4.

[0055] like Figure 4 and Figure 5 As shown, in one embodiment: the cleaning structure 9 includes a reduction gearbox 902 installed on one side of the combustion furnace 5, a servo motor 904 installed at the end of the input shaft of the reduction gearbox 902, a transmission shaft 903 installed at the end of the output shaft of the reduction gearbox 902 and rotatably connected to the first thermal insulation inner tank 17, a connecting rod 905 fixed to the outside of the transmission shaft 903, a scraper 901 fixed to one end of the connecting rod 905, and a fixed rod 906 fixed inside the scraper 901; by starting the servo motor 904 and driving the transmission shaft 903 to rotate through the reduction gearbox 902, the scraper 901 scrapes off the crystals on the inner wall of the first thermal insulation inner tank 17 and pushes the crystals to move toward the slag discharge port 4, thereby preventing metal salt crystals and other residues from corroding and wearing the interior of the equipment.

[0056] like Figure 4 and Figure 5 As shown, in one embodiment: a sliding structure is formed between the scraper 901 and the first insulation inner tank 17, the scraper 901 has a spiral structure, and the drive shaft 903 extends to the outside of the combustion furnace 5 and is connected to the reduction gear box 902; the spiral scraper 901 pushes the crystals to move toward the slag discharge port 4 during the rotation process to facilitate the discharge of the crystals.

[0057] like Figure 6 and Figure 7As shown, in one embodiment: the reciprocating structure 7 includes a bracket 704 fixed to the other side of the combustion furnace 5, a first transmission rod 709 rotatably connected to the inside of the bracket 704, a second bevel gear 706 fixed to the bottom end of the first transmission rod 709, a first bevel gear 705 meshingly connected to one side of the bottom end of the second bevel gear 706 and connected to the transmission shaft 903, a half gear 708 fixed to the top end of the first transmission rod 709, a moving frame 701 fixed to the outside of the injection pipe 15, and a slider 703 installed at the bottom end of the moving frame 701. The slide rail 702 slides on the outside of the slider 703 and is connected to the combustion furnace 5, the ring gear 707 is fixed at the bottom end of the slider 703 and meshed with the first transmission rod 709, and the sleeve 710 is slidably connected to the outside of the injection pipe 15 and is connected to the combustion furnace 5; the first bevel gear 705 is driven to rotate by the transmission shaft 903, so that the half gear 708 pushes the ring gear 707 to move left and right, thereby driving the atomizing nozzle 16 to move back and forth, ensuring that the waste liquid is evenly distributed in the first thermal insulation inner tank 17, avoiding local overheating or incomplete combustion.

[0058] like Figure 6 and Figure 7 As shown, in one embodiment: a ball bearing is installed at the connection position between the first transmission rod 709 and the bracket 704, and the slide rail 702 is symmetrically distributed on the vertical center line of the ring gear 707; the ball bearing is used to reduce the friction between the bracket 704 and the first transmission rod 709, so that the first transmission rod 709 rotates smoothly.

[0059] like Figure 8 and Figure 9 As shown, in one embodiment: the anti-blocking structure 8 includes a mounting base 801 fixed to one side of the combustion furnace 5, a pneumatic telescopic rod 802 installed inside the mounting base 801, a connecting frame 809 fixed to the telescopic end of the pneumatic telescopic rod 802 and slidably connected to the combustion furnace 5, a second transmission rod 806 rotatably connected to the inside of the connecting frame 809, a fourth bevel gear 812 fixed to one end of the second transmission rod 806, a cleaning brush 803 rotatably connected to one side of the connecting frame 809, a third bevel gear 811 installed at one end of the cleaning brush 803 and meshing with the fourth bevel gear 812, and a second transmission rod 806 fixed to the inside of the connecting frame 809. The spline 807 on the outside of 806, the rotating sleeve 808 slidingly connected to the outside of the spline 807, the second transmission wheel 805 fixed to the outside of the rotating sleeve 808, the fixing frame 810 rotatably connected to the outside of the rotating sleeve 808 and the first transmission wheel 804 fixed to the outside of the transmission shaft 903; the pneumatic telescopic rod 802 pushes the connecting frame 809 to drive the cleaning brush 803 to move to the bottom of the atomizing nozzle 16, and the transmission shaft 903 is used to drive the cleaning brush 803 to rotate to clean the bottom of the atomizing nozzle 16 to avoid clogging of the atomizing nozzle 16 and ensure that the atomizing nozzle 16 is always in good working condition.

[0060] like Figure 8and Figure 9 As shown, in one embodiment: the first transmission wheel 804 is connected to the second transmission wheel 805 through a transmission belt, and the second transmission rod 806 forms a sliding structure with the rotating sleeve 808 through the spline 807; through the transmission belt, the first transmission wheel 804 drives the second transmission wheel 805 to rotate, and the spline 807 slides inside the rotating sleeve 808, so that the connecting frame 809 can still drive the cleaning brush 803 to rotate during the process of driving the second transmission rod 806 to move left and right.

[0061] like Figure 10 As shown, in one embodiment: the discharge structure 3 includes a rotating shaft 304 rotatably connected to the inside of the slag discharge port 4, a pusher plate 303 fixed on the outside of the rotating shaft 304, a reinforcement bar 305 fixed between two adjacent groups of pusher plates 303, a driving motor 301 installed on one side of the slag discharge port 4 and with the output shaft end connected to the rotating shaft 304, a supporting shell 302 fixed at the top of the inside of the slag discharge port 4 and a baffle plate 306 fixed at the bottom of the inside of the slag discharge port 4; the driving motor 301 drives the pusher plate 303 to rotate through the rotating shaft 304 to push the crystals out, and the support shell 302 and the baffle plate 306 are used to make the pusher plate 303 seal the slag discharge port 4 during rotation, thereby avoiding the pollution of harmful gases to the environment.

[0062] Specifically, when the incineration equipment for treating salt-containing and chlorine-containing waste liquid is used: the pre-treated waste liquid is injected into the injection pipe 15 by a special high-pressure pump, and is evenly sprayed into the first insulation inner tank 17 in the form of mist or tiny droplets through the atomizing nozzle 16. In the first insulation inner tank 17, the first burner 6 is started to incinerate the waste liquid. The high-temperature flame causes the organic matter in the waste liquid to be rapidly oxidized and decomposed to generate waste gas, while the inorganic salts are melted or formed into granular deposition under the action of high temperature. In order to keep the first insulation inner tank 17 clean, the first burner 6 is started to incinerate the waste liquid. The cleaning structure 9 operates continuously to remove the inorganic salt particle crystals on the inner wall and push these crystals to move toward the slag discharge port 4. At the same time, the discharge structure 3 discharges the inorganic salt crystals smoothly while blocking the air flow. While the cleaning structure 9 is operating, the reciprocating structure 7 drives the atomizing nozzle 16 to move back and forth in the injection pipe 15 to ensure uniform spraying of the waste liquid. In addition, the anti-blocking structure 8 cleans the atomizing nozzle 16 in real time to prevent blockage. The exhaust gas generated by the incineration of the waste liquid is introduced into the combustion furnace 13 through the connecting pipe 10. At the same time, the combustion-supporting gas is injected into the second insulation inner tank 19 through the gas pipe 11 and the gas nozzle 18. The second burner 12 is then started to heat the second insulation inner tank 19, so that the organic matter in the exhaust gas is further oxidized and decomposed into carbon dioxide and water vapor, while the chlorine reacts with oxygen to generate hydrogen chloride. The ash generated in this process is discharged through the ash discharge port 2. Finally, the exhaust gas that has been completely burned is safely discharged through the exhaust pipe 14.

[0063] During the incineration process, the servo motor 904 is started to drive the reduction gearbox 902 to operate, and the reduction gearbox 902 drives the transmission shaft 903 to rotate. The transmission shaft 903 pushes the scraper 901 to move on the inner wall of the first heat-insulating inner container 17 through the connecting rod 905 to scrape off the crystals on the inner wall of the first heat-insulating inner container 17. At the same time, the spiral scraper 901 pushes the crystals to move toward the slag discharge port 4 during the rotation process to facilitate the discharge of the crystals. The scraper 901 is reinforced by the fixed rod 906 to prevent the scraper 901 from bending and deformation. The servo motor 904 transmits the speed and torque to the transmission shaft 903 through the reduction gearbox 902, so that the scraper 901 can scrape off the crystals.

[0064] During the operation of the cleaning structure 9, the transmission shaft 903 drives the first bevel gear 705 to rotate. At the same time, the first bevel gear 705 drives the second bevel gear 706 to rotate through the meshing of the teeth. At the same time, the second bevel gear 706 drives the first transmission rod 709 to rotate, and the half gear 708 pushes the ring gear 707 to move through the teeth. The slider 703 slides inside the slide rail 702 to guide the movement direction of the ring gear 707, so that the half gear 708 pushes the ring gear 707 to move left and right during the rotation. At the same time, the ring gear 707 is rotated by the meshing of the teeth. The slider 703 and the movable frame 701 drive the liquid injection pipe 15 to move back and forth, and the atomizing nozzle 16 to move back and forth, thereby expanding the spraying range of the atomizing nozzle 16, making the spraying of the atomizing nozzle 16 more uniform, and improving the incineration effect. The sliding sleeve 710 allows the liquid injection pipe 15 to slide inside the combustion furnace 5 and the first heat-insulating inner container 17. The first transmission rod 709 is supported by the bracket 704. At the same time, the ball bearing reduces the friction between the bracket 704 and the first transmission rod 709, so that the first transmission rod 709 rotates smoothly.

[0065] When the atomizing nozzle 16 is blocked from spraying, the pneumatic telescopic rod 802 is activated to retract, causing the pneumatic telescopic rod 802 to pull the connecting frame 809 backward, and causing the connecting frame 809 to drive the cleaning brush 803 to move to the bottom of the reciprocating atomizing nozzle 16. At the same time, the rotating transmission shaft 903 drives the first transmission wheel 804 to rotate, causing the first transmission wheel 804 to drive the second transmission wheel 805 to drive the rotating sleeve 808 to rotate through the transmission belt, and then the rotating rotating sleeve 808 drives the second transmission rod 806 to rotate through the spline 807. The second transmission rod 806 rotates, driving the cleaning brush 803 to rotate through the third bevel gear 811 and the fourth bevel gear 812. The rotating cleaning brush 803 is used to clean the bottom of the atomizing nozzle 16, remove the crystals on the surface of the atomizing nozzle 16, and ensure the smooth flow of the atomizing nozzle 16. The spline 807 slides inside the rotating sleeve 808, so that the connecting frame 809 can still drive the cleaning brush 803 to rotate during the process of driving the second transmission rod 806 to move left and right, and the rotating sleeve 808 is supported by the fixing frame 810.

[0066] When too much crystallization accumulates inside the slag discharge port 4, the drive motor 301 is started to rotate, so that the drive motor 301 drives the push plate 303 to rotate through the rotating shaft 304. At the same time, the rotating push plate 303 pushes the crystallization to move toward the slag discharge port 4, so that the crystallization is discharged. By utilizing the cooperation between the support shell 302 and the baffle plate 306, the push plate 303 is always in contact with the two groups of push plates 303, the support shell 302 and the baffle plate 306 during the rotation process, thereby sealing the inside of the slag discharge port 4 and preventing exhaust gas from leaking while discharging the crystallization.

[0067] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
