Description

Technical Field

[0001] The utility model belongs to the technical field of waste acid, and in particular relates to an oxygen-enriched incineration cracking furnace for regenerating waste acid. Background Art

[0002] Waste acid, also known as waste sulfuric acid, is generated in industrial production from processes such as nitration, esterification, sulfonation, alkylation, catalysis, and gas drying of organic matter, as well as from titanium dioxide production, steel pickling, and gas drying. Treatment of waste sulfuric acid primarily involves concentration, pyrolysis, chemical oxidation, extraction, crystallization, fertilizer production, and neutralization. Different companies typically employ different treatment processes based on the amount of waste sulfuric acid, its concentration, impurity composition and content, and the intended use of the treated sulfuric acid. Sometimes, a combination of these processes is required. Of these methods, only neutralization cannot regenerate sulfuric acid. Treatment of waste sulfuric acid primarily involves removing impurities and simultaneously increasing its concentration.

[0003] The waste sulfuric acid concentration process is suitable for treating small amounts of waste acid. During the heating and concentration process of dilute waste sulfuric acid, inorganic impurities (such as ferrous sulfate) in the waste sulfuric acid will crystallize and precipitate. During heating, an oxygen-enriched incineration and cracking furnace is usually required to heat the waste acid. Conventional incineration and cracking furnaces cannot guide the internal wind direction during use, which is prone to over-incineration and uneven heating, resulting in a decrease in the quality of the waste acid during decomposition and regeneration. Therefore, we propose an oxygen-enriched incineration and cracking furnace for waste acid regeneration. Utility Model Content

[0025] Example

[0026] See also Figure 1-5 , the technical solutions provided in this embodiment are as follows:

[0027] An oxygen-enriched incineration cracking furnace for waste acid regeneration comprises: a control console 1, a control panel 2 fixedly connected to the surface of the console 1, a cracking incinerator 3 fixedly connected to the back of the console 1, an igniter 4 provided on the surface of the cracking incinerator 3, an air guide assembly 5 provided on the inner wall of the cracking incinerator 3, a slag collecting assembly 6 fixedly connected to the bottom of the cracking incinerator 3, a plurality of supporting legs 7 fixedly connected to the surface of the cracking incinerator 3, a plurality of connecting pipes 10 fixedly connected to the inner wall of the cracking incinerator 3, a waste acid storage box 11 fixedly connected between the plurality of connecting pipes 10, and a connecting top cover 12 rotatably connected to the top of the cracking incinerator 3.

[0028] In this embodiment, the console 1 can use the control panel 2 to help the user control the entire device. At the same time, the cracking incinerator 3 can provide a place for waste acid regeneration. The igniter 4 is used to ignite the fuel inside the cracking incinerator 3 for incineration, and the heat generated can be evenly guided to the waste acid storage box 11 through the air guide component 5 to heat and regenerate the waste acid stored therein, further improving the overall waste acid regeneration effect of the device. At the same time, the slag generated after the fuel is burned can be centrally collected through the slag collection component 6. Large particles that will cause blockage will be excluded under the influence of the structure of the slag collection component 6, thereby ensuring smooth slag collection. At the same time, the support legs 7 can help support the entire device, further improving the overall stability of the device. The connecting pipe 10 can help fix the waste acid storage box 11 on the upper part of the inside of the cracking incinerator 3, so that this position is more convenient for heat absorption and oxygen injection, and the connecting top cover 12 can prevent heat dissipation, further improving the overall heating effect of the device.

[0029] The air guide assembly 5 includes a connecting plate 501, a rotating motor 502, a blower 503, an air duct 504 and an air outlet 505. Multiple connecting plates 501 are fixedly connected to the surface of the pyrolysis incinerator 3, the rotating motors 502 are fixedly connected to one side of the connecting plate 501, and the blower 503 is arranged on the top of the rotating motor 502.

[0030] In this embodiment, the air guide assembly 5 is fixed as a whole on both sides of the pyrolysis incinerator 3 by using the connecting plate 501. At the same time, the rotating motor 502 can help provide a rotation basis for the uniform rotation and heating of the entire air guide assembly 5.

[0031] The air delivery pipe 504 is rotatably connected to the rotating motor 502 , and a plurality of air outlets 505 are fixedly connected to the surface of the air delivery pipe 504 . The positions of the air outlets 505 match the bottom of the inner wall of the cracking incinerator 3 .

[0032] In this embodiment, the air duct 504 can be rotated by the rotating motor 502, so that the wind transmitted by the blower 503 can be evenly transported to the inside of the cracking incinerator 3. At the same time, the convection generated by the air supplied by the blowers 503 on both sides will rush towards the air outlet 505, thereby completing the control of the wind direction inside the cracking incinerator 3, helping heat to flow evenly inside the cracking incinerator 3, thereby further improving the efficiency of waste acid regeneration.

[0033] The slag collection assembly 6 includes a receiving bucket 601, a slag screen 602, a sliding groove 603, a sliding plate 604, a limiting plate 605 and a receiving bottom plate 606. The receiving bucket 601 is fixedly connected to the bottom of the inner wall of the pyrolysis incinerator 3, the slag screen 602 is fixedly connected to the top of the inner wall of the receiving bucket 601, and the sliding groove 603 is opened at the bottom of the inner wall of the sliding groove 603.

[0034] In this embodiment, the slag collection component 6 can use the storage barrel 601 to centrally collect the slag of the waste gas, and the slag screen 602 can centrally collect the slag of small particles that are more difficult to remove, thereby further improving the collection effect of the slag collection component 6. At the same time, the sliding groove 603 can help provide bottom installation, further improving the flexibility of the slag collection component 6.

[0035] The sliding plate 604 is slidably connected to the inner wall of the sliding groove 603, the limiting plate 605 is fixedly connected to one end of the sliding plate 604, and the storage bottom plate 606 is fixedly connected to the bottom of the sliding plate 604. The size of the storage bottom plate 606 matches the storage barrel 601.

[0036] In this embodiment, the sliding plate 604 is fixed to the bottom of the storage base plate 606. At the same time, the sliding plate 604 matches the sliding groove 603, which can drive the storage base plate 606 to slide on the bottom of the storage barrel 601 to form a container for the storage barrel 601 that can be disassembled and the internal slag can be removed at any time, further improving the usability of the slag collection component 6. At the same time, the limit plate 605 can help limit the position of the sliding plate 604 to prevent the storage base plate 606 from falling due to improper sliding, further improving the stability of the slag collection component 6.

[0037] An exhaust pipe 8 is fixedly connected to one side of the surface of the cracking incinerator 3 , and an exhaust valve 9 is rotatably connected to one side of the exhaust pipe 8 .

[0038] In this embodiment, the exhaust pipe 8 and the exhaust valve 9 can be linked to each other, and the user can open and close them at any time according to the internal conditions of the cracking incinerator 3, helping to stabilize the heat and flowing air inside the cracking incinerator 3, and further improving the overall safety and stability of the device.

[0039] A vent pipe 13 is fixedly connected to the top of the top cover 12 .

[0040] In this embodiment, the vent pipe 13 can help the user to input the required gas at any time to create the required environment for the waste acid regeneration, thereby further improving the overall functionality of the device.

[0041] Working principle: The user can control the operation of the entire device through the internal structure of the console 1 and the operation of the control panel 2, and use the linkage between multiple structures to increase the operability of the entire device. After the waste acid is placed in the waste acid storage box 11, the igniter 4 can be used to ignite the fuel inside the cracking incinerator 3 to burn and heat it. When the fire starts, the air guide component 5 can be started, and the internal structure of the air guide component 5 can be used to help guide and dredge the air inside the cracking incinerator 3, so as to evenly transport the heat to the waste acid storage box 11 for the regeneration of the waste acid. This improves the efficiency of waste acid heating and regeneration. At the same time, the incineration of fuel will produce more slag. Small particles of slag are not easy to be taken directly due to their size. At this time, the structure of the slag collection component 6 can be used to utilize gravity and the wind generated by the wind guide component 5 when in use to collect and take them together. Large particles of slag will be discharged to the bottom of the cracking incinerator 3 and can be taken directly. The structure of the slag collection component 6 is used to prevent large particles of slag from falling and blocking the outlet, further improving the overall safety of the device, and the ventilation pipe 13 can help provide an oxygen-rich environment for the inside of the cracking incinerator 3 at any time, further improving the overall functionality of the device.
