Description

Technical Field

[0001] This invention relates to an incineration treatment device, specifically a hazardous waste incineration treatment device. Background Technology

[0002] In industrial production and waste treatment, the incineration of hazardous waste is widely used because it can reduce and render harmless the waste. However, the exhaust gas produced by incineration has a complex composition, containing a large number of toxic and harmful substances, acid and alkali pollutants, and particulate matter. Its purification and treatment are far more difficult than ordinary incineration exhaust gas, making it a key problem in the field of environmental protection.

[0003] Existing hazardous waste incineration flue gas purification equipment generally suffers from complex structures and cumbersome operating procedures, which not only significantly increases equipment construction costs and subsequent maintenance difficulties but also reduces the ease of use in practice. Furthermore, the internal purification components of these devices have design flaws, making it difficult to fully mix and agitate the highly toxic and complex hazardous waste incineration flue gas. This results in insufficient and uneven contact between the flue gas and the purification materials, failing to effectively remove most highly hazardous impurities such as dioxins and heavy metals from the flue gas, and the purification effect is insufficient to meet actual needs.

[0004] Furthermore, due to the large and unstable acid-base differences in hazardous waste incineration flue gas, existing purification devices lack flexible and targeted purification mechanisms, making it impossible to perform in-depth treatment of the purified flue gas. This makes it difficult to ensure that the emitted flue gas meets stringent environmental standards, severely restricting the green and sustainable development of the hazardous waste incineration industry.

[0005] Therefore, developing a treatment device that is simple in structure, easy to use, can efficiently purify hazardous waste incineration exhaust gas, and can flexibly cope with exhaust gas of different acidity and alkalinity has become an important issue that urgently needs to be addressed.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1: Please refer to Figure 1 A hazardous waste incineration treatment device includes a base plate 1, a motor bracket 2 fixedly connected above the base plate 1, a drive motor 3 fixedly connected to the motor bracket 2, and a horizontal drive shaft 5 connected to the drive motor 3 via a coupling 4. A purification treatment box 6 is arranged above the base plate 1, and a stirring assembly 7 is arranged inside the purification treatment box 6. The stirring assembly 7 is drivenly connected to the horizontal drive shaft 5. A secondary purification assembly 8 is also arranged above the base plate 1, and the secondary purification assembly 8 is drivenly connected to the horizontal drive shaft 5.

[0026] During use, a purification solution is placed inside the purification treatment tank 6. Different purification solutions can be selected according to different purification needs, including but not limited to acidic and alkaline absorption solutions, redox absorption solutions, catalytic purification solutions, and biological purification solutions. After the incineration exhaust gas enters the purification treatment tank 6, it can undergo preliminary purification. Under the stirring action of the stirring component 7, the purification effect can be guaranteed.

[0027] Please see Figure 1 and Figure 3The bottom of the purification treatment box 6 is fixedly connected to a support frame 9, which is fixedly connected to the equipment base plate 1. The stirring assembly 7 includes a stirring shaft 10 rotatably connected to the bottom of the purification treatment box 6. Stirring blades 11 are fixedly connected to the outside of the stirring shaft 10. A driven bevel gear 12 is fixedly connected to the bottom of the stirring shaft 10. A driving bevel gear 13 is fixedly connected to the end of the horizontal drive shaft 5. The driving bevel gear 13 meshes with the driven bevel gear 12.

[0028] The purified exhaust gas enters the secondary purification component 8, and after secondary purification, it can be discharged. The drive motor 3 rotates, which drives the horizontal drive shaft 5 to rotate, which in turn drives the active bevel gear 13 and the driven bevel gear 12 to rotate. The driven bevel gear 12 drives the stirring blade 11 to rotate and stir, so that the purified liquid can fully contact the incoming exhaust gas, greatly improving the purification effect.

[0029] The bottom of the equipment base plate 1 is fixedly connected to casters 14, which facilitates the movement of the device. A liquid injection pipe 15 is fixedly connected to the top of the purification treatment box 6, and a cap 16 is fixedly connected to the top of the liquid injection pipe 15. The liquid injection pipe 15 facilitates the injection of purification liquid, while the cap 16 provides a seal. A drain pipe is also connected to the bottom of the purification treatment box 6 to drain any poorly treated purification liquid. An inlet duct 17 for introducing incineration exhaust gas is fixedly connected to the side wall of the purification treatment box 6, and an outlet duct 18 for discharging the treated exhaust gas is also connected to the side wall. The treated exhaust gas enters the secondary purification component 8 through the outlet duct 18.

[0030] The secondary pipe 22 rotates under the drive of the drive motor 3. During the rotation, the secondary pipe 22 will cooperate with the exhaust pipe 18. When the secondary pipe 22 cooperates with the exhaust pipe 18, they will be connected, allowing the exhaust gas to enter the purification unit 21 through the secondary pipe 22. After being purified by the purification filter element 27 inside the purification unit 21, the exhaust gas is fully treated and can then be discharged directly.

[0031] The secondary purification component 8 includes a guide mounting frame 19, on which a rotating pipe 20 is rotatably connected. Two purification units 21 are connected to the rotating pipe 20, and each purification unit 21 is connected to a secondary pipeline 22. Each end of the secondary pipeline 22 is fixedly connected to an electric control switch 23. An electric control valve 24 is fixedly connected to the end of the exhaust duct 18. When the electric control switch 23 and the electric control valve 24 cooperate, the exhaust duct 18 is opened. The secondary purification component 8 is connected to the horizontal drive shaft 5 via a transmission unit 25. Each purification unit 21 includes a purification sleeve 26, inside which purification filter elements 27 are evenly distributed. Different purification filter elements 27 can be selected for exhaust gases with different acidity or alkalinity. The switching of the purification filter elements 27 is achieved through the transmission unit 25.

[0032] Example 2: This example is an improvement on the previous example, with the following modifications: Please refer to... Figure 1 , Figure 2 and Figure 4 The transmission unit 25 includes an active dial 28 fixed to the outside of the horizontal drive shaft 5, a transmission shaft 29 rotatably connected to the guide mounting bracket 19, a driven grooved wheel 30 fixedly connected to the outside of the transmission shaft 29 and cooperating with the active dial 28, a transmission sleeve 31 slidably connected to the outside of the transmission shaft 29, the transmission sleeve 31 and the transmission shaft 29 not rotating relative to each other, a driving gear 32 fixedly connected to the outside of the transmission sleeve 31, and a driven gear 33 fixedly connected to the outside of the rotating tube 20, the driving gear 32 and the driven gear 33 meshing. The driven grooved wheel 30 has 6 grooves, and the gear ratio of the driving gear 32 to the driven gear 33 is 3.

[0033] The active dial 28 drives the driven grooved wheel 30 to rotate periodically. Since there are six grooves, each rotation causes the driven grooved wheel 30 to rotate by 60°. Through gear transmission with a gear ratio of 3, the rotating tube 20 rotates exactly 180°. This effectively allows for the switching between the upper and lower purification units 21. After switching, with the driven grooved wheel 30 in a gap, sliding the transmission sleeve 31 outwards disengages the active gear 32 from the driven gear 33, allowing for the switching of the purification filter element 27 when needed, greatly improving ease of use.

[0034] Working Principle: During use, a purification liquid is placed inside the purification treatment tank 6. Different purification liquids can be selected according to different purification needs, including but not limited to acidic and alkaline absorption liquids, redox absorption liquids, catalytic purification liquids, and biological purification liquids. After the incineration exhaust gas enters the purification treatment tank 6, it undergoes initial purification. The purification effect is ensured by the stirring action of the stirring component 7. The purified exhaust gas then enters the secondary purification component 8, where it undergoes secondary purification before being discharged. The drive motor 3 rotates, causing the horizontal drive shaft 5 to rotate, which in turn drives the active bevel gear 13 and the driven bevel gear 12 to rotate. The driven bevel gear 12 drives the stirring blades 11 to rotate, ensuring that the purification liquid fully contacts the entering exhaust gas, greatly improving the purification effect. Driven by the motor 3, the secondary pipe 22 rotates. During rotation, different secondary pipes 22 engage with the exhaust duct 18. When the secondary pipe 22 engages with the exhaust duct 18, they connect, allowing the exhaust gas to enter the purification unit 21 through the secondary pipe 22. After being purified by the purification filter element 27 inside the purification unit 21, the exhaust gas is fully treated and can then be directly discharged. Different purification filters 27 can be selected for exhaust gases with different acidity or alkalinity. The switching of the purification filter element 27 is achieved through the transmission unit 25. The active dial 28 drives the driven groove wheel 30 to rotate periodically. Since there are 6 grooves, the driven groove wheel 30 rotates 60° each time during rotation. Through gear transmission with a gear ratio of 3, the rotation of the rotating pipe 20 is exactly 180°. This effectively achieves the switching between the upper and lower purification units 21. After the switching is completed, with the driven gear 30 rotating with a gap, the transmission sleeve 31 slides outward, which allows the driving gear 32 and the driven gear 33 to disengage, thereby allowing the purification filter element 27 to be switched when needed, greatly improving the ease of use.
