Description

Technical Field

[0001] The invention relates to the technical field of waste liquid treatment, and 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 caused by direct discharge of waste liquid to the environment, 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 body, the incinerator body is fixedly connected to the heat-conducting ceramic plate, and a preheating box is installed on the upper end of the heat-conducting ceramic plate. 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, it is beneficial to improve the incineration efficiency of the waste liquid and enhance the practicality of the device. The installation of hot air flow blades can make it rotate under the action of the hot air flow. The rotation of the hot air flow blades will drive the atomizing spray pipe to rotate, thereby enhancing the flexibility of the device, and can perform 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 incineration efficiency of the waste liquid. 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 the 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 that the nozzle is easy to be blocked. After the nozzle sprays the waste liquid, some crystals are easily precipitated on the surface of the nozzle, causing the nozzle to be blocked, affecting the use of the nozzle of the device; (4) There is a defect that the waste gas is easy to leak. 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

[0015] Compared with the prior art, the present invention provides an incineration device for treating salt-containing and chlorine-containing waste liquid, which has the following beneficial effects: 1. The incineration equipment for treating salt-containing and chlorine-containing waste liquid drives the transmission shaft to rotate through the servo motor via the reduction box, so that the scraper scrapes off the crystals on the inner wall of the first insulation tank and pushes these crystals to move toward the slag discharge port, realizing all-round cleaning of the inner wall.

The incineration equipment for treating salt-containing 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 gear ring enables the atomizing nozzle to reciprocate in the first heat-insulating inner tank, ensuring that the waste liquid can be evenly distributed, avoiding the problem of local overheating or uneven combustion, so that the organic matter and inorganic salts in the waste liquid can be burned more fully and thoroughly, and the incineration efficiency is significantly improved; 3. The incineration equipment for treating salt-containing and chlorine-containing waste liquid drives the cleaning brush to move accurately to the bottom of the atomizing nozzle through the combination of the pneumatic telescopic rod and the cleaning brush. Then, the rotational power of the transmission shaft is used to gently rotate the cleaning brush to clean the bottom of the atomizing nozzle. This not only realizes the nozzle cleaning function, but also keeps the atomizing nozzle in the best working state at all times, and ensures the adequacy and efficiency of the incineration process. 4. The incineration equipment for treating salt- and chlorine-containing waste liquid continuously pushes the crystals to the slag discharge port through the driving push plate of the rotating shaft via the driving motor. At the same time, the supporting shell and the baffle plate enable the push plate to tightly seal the slag discharge port during the rotation process, which is convenient for the smooth discharge of solid waste such as slag and fly ash, and effectively prevents the leakage of internal gas, thus avoiding the pollution of the environment by harmful gases.

The spline 807 on the outside of 806, the rotating sleeve 808 slidably 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 drives the cleaning brush 803 to rotate to clean the bottom of the atomizing nozzle 16 to avoid blockage of the atomizing nozzle 16 and ensure that the atomizing nozzle 16 is always in good working condition.

[0026] like Figure 8and Fig. 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.

[0027] like Fig.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 strip 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 supporting 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 the environment by harmful gases.

[0028] 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 heat-insulating inner tank 17 in the form of mist or tiny droplets through the atomizing nozzle 16. In the first heat-insulating 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 salt melts or forms granular deposition under the action of high temperature. In order to keep the first heat-insulating inner tank 17 clean, the first burner 6 is started to burn 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 waste 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 heat-insulating inner tank 19 through the gas pipeline 11 and the gas nozzle 18. The second burner 12 is then started to heat the second heat-insulating inner tank 19, so that the organic matter in the waste gas is further oxidized and decomposed into carbon dioxide and water vapor, and 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 completely burned waste gas is safely discharged through the exhaust pipe 14. During the incineration process, the servo motor 904 is started to drive the reduction box 902 to operate, and the reduction box 902 drives the transmission shaft 903 to rotate. The transmission shaft 903 pushes the scraper bar 901 to move on the inner wall of the first heat-insulating inner tank 17 through the connecting rod 905 to scrape off the crystals on the inner wall of the first heat-insulating inner tank 17. At the same time, the spiral scraper bar 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 bar 901 is reinforced by the fixed rod 906 to prevent the scraper bar 901 from bending and deformation. The servo motor 904 transmits the speed to the transmission shaft 903 through the reduction box 902 and increases the torque, so that the scraper bar 901 can scrape off the crystals. During the operation of the cleaning structure 9, the transmission shaft 903 drives the first bevel gear 705 to rotate, and 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 The slider 703 and the moving frame 701 drive the injection pipe 15 to move back and forth, and the atomizing nozzle 16 to move back and forth, so as to expand the spraying range of the atomizing nozzle 16, make the atomizing nozzle 16 spray more evenly, and improve the incineration effect. The sliding sleeve 710 makes it easy for the injection pipe 15 to slide inside the combustion furnace 5 and the first heat-insulating inner tank 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. When the atomizing nozzle 16 is blocked from spraying, the pneumatic telescopic rod 802 is activated to retract, so that the pneumatic telescopic rod 802 pulls the connecting frame 809 to move backward, and the connecting frame 809 drives 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, so that the first transmission wheel 804 drives 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 is rotated to drive the cleaning brush 803 to rotate through the third bevel gear 811 and the fourth bevel gear 812, and the bottom of the atomizing nozzle 16 is cleaned by the rotating cleaning brush 803 to remove the crystals on the surface of the atomizing nozzle 16 to 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; When too much crystals accumulate inside the slag discharge port 4, start the drive motor 301 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 crystals to move toward the slag discharge port 4 to discharge the crystals. 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, so as to seal the inside of the slag discharge port 4 and prevent exhaust gas from leaking while discharging the crystals.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The high-temperature flame rapidly oxidizes and decomposes organic matter in the waste liquid to generate waste gas. At the same time, the inorganic salt melts or precipitates in a granular form at high temperature. S4: Internal cleaning: The inorganic salt particle crystals on the inner wall of the first heat-insulating inner container (17) are cleaned by the cleaning structure (9), and the crystals are pushed to move toward the slag discharge port (4).

The second burner (12) is started to heat the interior of the second heat-insulating inner container (19), 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 generate hydrogen chloride. The ash generated in this process is discharged through the ash discharge port (2); S6: Tail gas treatment: The completely burned exhaust gas is discharged through the exhaust pipe (14) and is purified by cooling, dust removal, desulfurization, denitrification and other treatments. After meeting the emission standards, it is discharged into the atmosphere through the chimney.
