Description

Technical Field

[0001] The present invention relates to the technical field of waste gas incineration, in particular to a waste gas incineration device with a multi-stage purification function. Background Art

[0002] Waste gas incineration is an important method for treating combustible and hazardous substances in waste gas. Its basic principle is to introduce waste gas into specialized incineration equipment, such as an incinerator. Under high temperatures (typically 800-1200°C) and sufficient oxygen, combustible components in the waste gas, such as organic matter and some inorganic substances, undergo a violent chemical reaction with oxygen, producing harmless or low-harm substances such as carbon dioxide and water vapor, while releasing heat. This not only effectively removes harmful substances from the waste gas and reduces its environmental pollution, but also enables a certain degree of energy reuse through methods such as heat recovery.

[0003] However, existing incineration mechanisms usually carry out incineration after simple treatment, so the exhaust gas often contains other harmful substances that are incinerated together, which leads to incomplete exhaust gas treatment and environmental pollution. At the same time, the existing exhaust gas incineration mechanism equipment is highly complex and needs to be equipped with a waste heat recovery system and a heat exchanger, resulting in a large size and a long installation cycle, which in turn leads to high operating costs.

[0004] Therefore, the present invention provides a waste gas incineration device with a multi-stage purification function to solve the above problems. Summary of the Invention

[0044] In this embodiment, a combustion-supporting device 43 is provided in the incineration tower 41, and the guide spiral piece 435 is driven by a motor to transport oxygen into the incineration tower 41, and then the exhaust gas in the incineration tower 41 is incinerated at high temperature in cooperation with the combustion device 47. At the same time, the rotating disk 438 is driven to rotate during the rotation of the guide spiral piece 435, and then the rotating fan blade 436 is driven to better transport oxygen while scraping off impurities attached to the screen 44, thereby ensuring complete combustion of the exhaust gas. At the same time, a pretreatment component 2 is provided, and the large particles of impurities in the exhaust gas are adsorbed by the activated carbon block 24 in the pretreatment mechanism, thereby avoiding impurities. Entering the incineration tower 41 causes incomplete incineration. At the same time, by setting up two pretreatment mechanisms, it is possible to stop the replacement immediately when the activated carbon block 24 needs to be replaced without interrupting the entire reaction process, thereby improving the incineration efficiency; at the same time, the exhaust gas is also sprayed through the spray component 3, and different solutions are sprayed on the exhaust gas with different components through the spray component 3, so that they react chemically with the components in the exhaust gas, and then further treat the exhaust gas, thereby ensuring that the exhaust gas has removed harmful substances that cannot be removed by incineration before entering the incineration component 4, and then cooperates with incineration to ensure that the harmful substances in the exhaust gas are completely treated.

[0046] During operation, the exhaust gas enters the pre-treatment component 2 from the air inlet 33 and then contacts the activated carbon block 24. The activated carbon block 24 adsorbs the solid particles in the exhaust gas, and then the adsorbed exhaust gas is transported to the spray component 3.

[0047] Through the design of the pretreatment component 2, efficient preliminary adsorption of solid particles in the exhaust gas is achieved. The pretreatment box 22 adopts a structure with a square cross-section, and through the fixed plate 23 and activated carbon block 24 installed in an array, the adsorption area and efficiency are greatly improved, ensuring that most of the solid particles in the exhaust gas are removed before entering the subsequent treatment link, reducing the processing burden of subsequent equipment. The stable support structure of the support frame 21 and the compact design of the pretreatment box 22 enhance the overall stability of the device, while reducing the equipment's footprint and installation complexity, facilitating integrated application in different industrial environments. The modular installation method of the activated carbon block 24 facilitates regular replacement and maintenance, reduces operating costs, and ensures long-term stable adsorption performance.

[0048] Specifically, refer to Figure 1 The pretreatment components 2 are provided with two groups. By providing the pretreatment components 2 with two groups, when the activated carbon block 24 needs to be replaced, the replacement can be stopped immediately without interrupting the entire reaction process, thereby improving the incineration efficiency.

[0050] During operation, the exhaust gas enters the spray tower 32 through the air inlet 33. At this time, the water pump 37 pumps water from the water tank 36 to the spray rack 39 through the water pipe 38 to spray the exhaust gas, thereby further removing harmful substances in the exhaust gas through chemical reactions. At this time, the sprayed liquid flows through the collection nozzle 34 to the collection box 35 for collection.

[0051] By using the above-mentioned spray component 3, different solutions are sprayed on the waste gas with different components through the spray component 3, so that they react chemically with the components in the waste gas, and then the waste gas is further treated, thereby ensuring that the waste gas has removed harmful substances that cannot be removed by incineration before entering the incineration component 4, and then combined with incineration to ensure that the harmful substances in the waste gas are completely treated.

[0052] Specifically, refer to Figure 4 The spray tower 32 is provided with a filter disc 321 for filtering.

The interception effect of the filter disc 321 can effectively prevent solid particles in the exhaust gas from entering the nozzle, thereby avoiding nozzle blockage and ensuring the normal operation of the spray system. The filtered exhaust gas is then sprayed for better contact between the spray liquid and the exhaust gas, thereby enhancing the chemical reaction effect, further removing harmful substances in the exhaust gas, and improving the overall purification effect.

The incineration tower 41 is installed on one side of the spray assembly 3. The incineration tower 41 is used to incinerate the exhaust gas; an air inlet nozzle 42 is provided at the bottom of the incineration tower 41, and the air inlet nozzle 42 is used to transport the exhaust gas into the incineration tower 41; a combustion-supporting device 43 is installed in the air inlet nozzle 42, and the combustion-supporting device 43 is used to transport the combustion-supporting gas into the incineration tower 41; a screen 44 is installed at the bottom of the incineration tower 41, and the screen 44 It is used to filter the exhaust gas and the waste generated after incineration; a transition sleeve 45 is installed above the screen 44, and the filter sleeve is used to evenly filter the exhaust gas; a combustion chamber 46 is installed above the transition sleeve 45, and the combustion chamber 46 is used to burn the exhaust gas; a combustion device 47 is installed in the combustion chamber 46, and the combustion device 47 is used to burn the exhaust gas; a buffer chamber 48 is installed above the combustion chamber 46, and the buffer chamber 48 is used to buffer the treated exhaust gas; an exhaust port 49 is provided on the buffer chamber 48; the exhaust port 49 is used to discharge the exhaust gas out of the incineration tower 41;

At this time, the exhaust gas is filtered by the screen 44 and then evenly enters the combustion chamber 46 through the transition sleeve 45. At the same time, the combustion-supporting device 43 also transports the combustion-supporting gas into the combustion chamber 46. At this time, the combustion device 47 starts to burn the exhaust gas, decomposing the harmful exhaust gas, and then the harmless gas is buffered by the buffer chamber 48 and discharged from the exhaust port 49.

[0057] The multi-stage structural design of the incineration component 4 enables efficient incineration of waste gas. After the waste gas enters the incineration tower 41 through the air inlet nozzle 42, it is first filtered through the screen 44 to remove some particulate matter, and then evenly distributed through the degree sleeve 45 to enter the combustion chamber 46.

The treated waste gas is pressure-stabilized and buffered in the buffer chamber 48, and finally discharged through the exhaust port 49. This design improves the incineration efficiency, ensures the complete decomposition of harmful gases, and at the same time stabilizes the airflow through the buffer chamber 48, optimizes the emission effect, effectively reduces the emission of harmful gases, and reduces the risk of environmental pollution.

[0058] Specifically, refer to Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 The combustion-supporting device 43 includes a combustion-supporting box 431, a combustion-supporting delivery pipe 432, a combustion-supporting motor 433, a reducer 434 and a guide spiral piece 435; the combustion-supporting box 431 is installed on one side of the incineration tower 41, and the combustion-supporting box 431 is used to store combustion-supporting gas; a combustion-supporting delivery pipe 432 is installed on one side of the combustion-supporting box 431, and the combustion-supporting delivery pipe 432 is used to deliver combustion-supporting gas; a combustion-supporting motor 433 is installed on one side of the combustion-supporting delivery pipe 432, and the combustion-supporting motor 433 is used to drive the reducer 434 to rotate; a reducer 434 is installed at the output end of the combustion-supporting motor 433, and the reducer 434 is used to reduce the speed of the combustion-supporting motor 433 and drive the guide spiral piece 435 to rotate; a guide spiral piece 435 is installed at the output end of the reducer 434, and the rotation of the guide spiral piece 435 drives the combustion-supporting gas and exhaust gas to enter the interior of the incineration tower 41 for incineration;

[0059] During operation, the combustion-supporting motor 433 starts to drive the reducer 434 to rotate, and the output end of the reducer 434 drives the guide spiral 435 to rotate. The rotating guide spiral 435 drives the combustion-supporting gas from the combustion-supporting box 431 to the inside of the incineration tower 41, and at the same time drives the exhaust gas to be transported to the inside of the incineration tower 41 for incineration;

[0060] The combustion-supporting motor 433 drives the reducer 434, which in turn rotates the guide spiral 435, transporting the combustion-supporting gas from the combustion-supporting tank 431 into the incinerator 41. This design also drives the waste gas into the incinerator 41 for incineration. This design improves incineration efficiency, ensures that the waste gas and the combustion-supporting gas are fully mixed, and achieves complete decomposition of harmful gases, thereby enhancing the treatment effect.

[0061] Specifically, refer to Figure 9 The bottom of the incinerator 41 is equipped with a rotating blade 436, and the rotating blade 436 is provided with two upper and lower ones. The rotating blade 436 is installed at the bottom of the incinerator 41 through a rotating rod 437; the rotating blade 436 at the upper end is in contact with the screen 44, and the rotating blade 436 at the lower end is equipped with a rotating disk 438, and the rotating disk 438 is engaged with the guide spiral sheet 435;

[0062] The rotating blades 436 at the top are used to scrape impurities from the screen 44, and the spiral blades at the bottom are used to mix the flame-retardant gas and the exhaust gas so that the exhaust gas can be burned evenly. The rotation of the guide spiral 435 drives the rotating disk 438 to rotate, and the rotation of the rotating disk 438 drives the rotating blades 436 to rotate.

[0063] The rotation of guide spiral blades 435 drives rotating disk 438 and rotating blades 436. Rotating blades 436 at the upper end scrape impurities from screen 44, preventing clogging, extending the service life of screen 44, and ensuring smooth passage of exhaust gas. Rotating blades 436 at the lower end thoroughly mix the combustion-supporting gas and exhaust gas, ensuring more uniform and complete combustion of the exhaust gas, improving combustion efficiency, and reducing harmful gas emissions.

[0064] Specifically, refer to Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12, the combustion device 47 includes an air intake valve 471, an air uniforming bin 472, a spiral conveying pipe 473, a combustion nozzle 474 and an igniter 475. The air intake valve 471 is installed on one side of the incineration tower 41. The air intake valve 471 is used to transport the combustion gas into the air uniforming bin 472; an air uniforming bin 472 is installed at one end of the air intake valve 471, and the air uniforming bin 472 is used to uniformly distribute the combustion gas; a spiral conveying pipe 473 is installed in an array at the bottom of the air uniforming bin 472, and the combustion conveying pipe is used to transport the combustion gas; the spiral conveying pipe 473 is in a spiral array on the outside of the combustion bin 46, and the length of the spiral conveying pipe 473 is extended by the spiral array, thereby achieving a better combustion effect; the other end of the spiral conveying pipe 473 extends into the interior of the combustion bin 46 and is equipped with a combustion nozzle 474 at the end, and the combustion nozzle 474 is used to burn the exhaust gas; the combustion nozzle 474 is equipped with an igniter 475, and the igniter 475 is used to ignite the combustion nozzle 474;

[0065] During operation, the combustion gas enters the gas homogenizing chamber 472 through the gas inlet valve 471, and then enters the spiral conveying pipe 473 after being homogenized by the gas homogenizing chamber 472. The spiral conveying pipe 473 conveys the gas to the combustion nozzle 474. At this time, the large igniter 475 ignites the combustion nozzle 474 to burn and incinerate the exhaust gas.

[0066] After entering the uniform gas chamber 472 through the inlet valve 471 and being evenly distributed, the combustion gas is delivered to the combustion nozzle 474 via the spiral array of spiral conveying pipes 473, extending the gas path and enhancing the mixing effect. The igniter 475 automatically ignites, ensuring stable combustion in the combustion nozzle 474 and sufficient decomposition of the exhaust gas at high temperatures. This design improves combustion efficiency and ensures thorough exhaust gas treatment. Furthermore, the synergistic effect of the uniform gas chamber 472 and the spiral conveying pipe 473 optimizes the combustion process and reduces harmful gas emissions.

[0067] The overall working process is as follows: during operation, the exhaust gas enters the pre-treatment component 2 from the air inlet 33, and then comes into contact with the activated carbon block 24. The activated carbon block 24 adsorbs the solid particles in the exhaust gas, and then the adsorbed exhaust gas is transported to the spray component 3;

[0068] The exhaust gas enters the spray tower 32 through the air inlet 33. At this time, the water pump 37 pumps water from the water tank 36 through the water pipe 38 to the spray rack 39 to spray the exhaust gas. The harmful substances in the exhaust gas are further removed through chemical reactions. At this time, the sprayed liquid flows through the collection nozzle 34 to the collection box 35 for collection.

[0069] The waste gas after spraying enters the incineration component 4 through the air inlet nozzle 42. At this time, the waste gas is filtered by the screen 44 and then evenly enters the combustion chamber 46 through the transition sleeve 45. At the same time, the combustion-supporting device 43 also transports combustion-supporting gas into the combustion chamber 46. At this time, the combustion device 47 starts to burn the waste gas to decompose the harmful waste gas, and then the harmless gas is buffered by the buffer chamber 48 and discharged from the exhaust port 49.

[0070] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
