Technical Field

[0001] The present invention relates to the technical field related to incinerators, and in particular to a smoke purification device for an incinerator. Background Art

[0002] An incinerator is a tool used in waste recovery technologies that include burning materials and organic materials. The main equipment available on the waste incineration technology market includes grate incinerators, fluidized bed (bubbling and circulating fluidized bed) incinerators, rotary kiln incinerators, and pyrolysis gasifiers. Incinerators and other high-temperature waste recovery systems can be described as "heat recovery". Incinerators convert waste into ash, exhaust gas, particulates, and heat, which can in turn be used to generate electricity. Exhaust gas and other pollutants will be cleaned before entering the air. Incinerators and energy recovery are one of many waste-to-energy conversion technologies such as gasification, pyrolysis, and anaerobic digestion. Since incinerators tend to form smoke with more pollutants during the combustion process, a purification device is needed to purify the smoke before it is discharged.

[0003] During use, the existing smoke purification device generally needs to use a fan to introduce the smoke in the incinerator into the purification equipment. However, in the process of the fan attracting the smoke, there is no structure that can filter the smoke sucked in by the fan. This causes some large impurities or debris generated during the incineration process to easily enter the fan due to the attraction of the fan and hit the internal structure of the fan, causing damage to the fan, thereby directly affecting the smoke purification effect of the incinerator. There is room for improvement.

[0004] The purpose of the present invention is to provide an incinerator smoke purification device to solve the problem that the existing smoke purification equipment proposed in the above background technology has no structure to protect the fan, resulting in some large-volume impurities and debris being easily sucked into the fan during the smoke suction process, causing damage to the fan.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an incinerator smoke purification device, comprising an incinerator body and a purification box, the upper surface of the purification box is fixedly connected with an induced draft fan, the input end of the induced draft fan is connected with an air intake pipe, and the output end is connected with a delivery pipe, the upper surface of the incinerator body is fixedly connected with a protective component, the front of the purification box is threadedly connected with a sealing cover, the front of the purification box is connected with a drain pipe, the surface of the drain pipe is installed with a solenoid valve, the left side of the purification box is fixedly connected with a centrifugal component, and the left side of the purification box is fixedly connected with an exhaust component; The protection component comprises a right-angle frame, the right side of the right-angle frame is connected with a right-angle pipe, the inner top wall of the incinerator body is fixedly connected with a dust collecting hood, the lower surface of the right-angle frame is provided with a rectangular hole, the inner wall of the rectangular hole is slidably connected with a bottom plate, the upper surface of the bottom plate is fixedly connected with two vertical plates, a retaining net is inserted between the two vertical plates, the opposite back surfaces of the two vertical plates are provided with circular slots, the front and back sides of the right-angle frame are fixedly connected with sleeves, the inner wall of the sleeve is slidably connected with a movable plate, the front side of the sleeve is provided with a circular hole, the inner wall of the circular hole is slidably connected with a limiting push rod, and the surface of the limiting push rod is sleeved with a spring; The centrifugal assembly includes a driving motor, the output end of the driving motor is fixedly connected to a round rod, the right end of the round rod is fixedly connected to a first bevel gear, the inner bottom wall of the purification box is rotatably connected to a rotating rod, the surface of the rotating rod is fixedly connected to a second bevel gear, and the surface of the rotating rod is fixedly connected to two sets of stirring arms; The exhaust assembly includes an internal threaded sleeve, the inner wall of the internal threaded sleeve is threadedly connected to an external threaded connector, the left end of the external threaded connector is fixedly connected to an exhaust pipe, the inner wall of the exhaust pipe is fixedly connected to an activated carbon filter, and the left end of the exhaust pipe is fixedly connected to an exhaust hood.

The smoke entering the purification box 2 will be directly aerated with the purified liquid in the purification box 2 through the conveying pipe 5. At the same time, the driving motor 19 drives the first bevel gear 21 to rotate through the round rod 20, thereby driving the second bevel gear 23 and the rotating rod 22 to rotate, and driving the stirring arm 24 to stir the purified liquid, ensuring that during the aeration process, the contact area between the purified liquid and the aerated smoke is increased, thereby improving the purification effect of the smoke; The exhaust assembly includes an internal threaded sleeve 25, the inner wall of the internal threaded sleeve 25 is threadedly connected to an external threaded connector 26, the left end of the external threaded connector 26 is fixedly connected to an exhaust pipe 27, the inner wall of the exhaust pipe 27 is fixedly connected to an activated carbon filter 28, and the left end of the exhaust pipe 27 is fixedly connected to an exhaust hood 29. After the aerated smoke contacts and reacts with the purified liquid, it moves upward in the purification box 2 and is finally discharged through the exhaust pipe 27. When it is on the inner wall of the exhaust pipe 27, it can be filtered twice through the activated carbon filter 28 before being discharged, which further improves the environmental protection effect. In addition, the activated carbon filter 28 can be quickly removed through the internal threaded sleeve 25 and the external threaded connector 26, and has high flexibility.

[0019] Furthermore, one end of the air inlet pipe 4 away from the induced draft fan 3 is connected to the interior of the right-angle frame 9, and one end of the conveying pipe 5 away from the induced draft fan 3 is connected to the interior of the purification box 2. The induced draft fan 3 can attract and convey the smoke in the incinerator body 1 to the interior of the purification box 2 through the air inlet pipe 4 and the right-angle frame 9, filter the smoke and then discharge it, which can improve the protection effect of the air environment.

[0020] Furthermore, one end of the right-angle tube 10 away from the right-angle frame 91 is connected to the interior of the dust hood 11, and the smoke inside the incinerator body 1 can enter the right-angle frame 9 through the dust hood 11 and the right-angle tube 10. Under the blocking effect of the blocking net 14, the large volume of impurities and debris in the smoke will be blocked by the blocking net 14 and retained inside the right-angle frame 9. They will not enter the interior of the induced draft fan 3 through the air inlet pipe 4 to cause any damage to the induced draft fan 3, thereby improving the protection effect of the induced draft fan 3 and extending the service life of the induced draft fan 3.

[0021] Furthermore, a through hole is provided on the front side of the movable plate 16 , and the movable plate 16 is fixedly connected to the surface of the limiting push rod 17 through the through hole. When the limiting push rod 17 moves forward, it can drive the movable plate 16 to move in the sleeve 15 .

[0022] Furthermore, the opposite ends of the two limiting push rods 17 extend into the interior of the rectangular hole and are adapted to the circular slots on the back sides of the two vertical plates 13. The two limiting push rods 17 can be inserted into the rectangular hole and into the two circular slots to lock the positions of the bottom plate 12 and the two vertical plates 13.

[0023] Furthermore, one end of the spring 18 overlaps the inner wall of the sleeve 15, and the other end overlaps the movable plate 16. When the movable plate 16 moves forward, it can squeeze the spring 18 to cause it to deform, and make the limiting push rod 17 disengage from the circular slot, thereby removing the restriction on the vertical plate 13. After the vertical plate 13 loses the restriction, the bottom plate 12 can be pulled out from the bottom of the right-angle frame 9, so that the bottom plate 12 drives the vertical plate 13 to disengage from the inside of the right-angle frame 9, thereby facilitating the cleaning of large-volume impurities and debris on the bottom plate 12, ensuring that these large-volume impurities and debris will not accumulate too much inside the right-angle frame 9, affecting the suction effect of the induced draft fan 3 on smoke and dust, and after the cleaning is completed, the limiting push rod 17 can be used to quickly lock the vertical plate 13, which has high flexibility.

[0024] Furthermore, the right end of the round rod 20 extends to the interior of the purification box 2, and the first bevel gear 21 is meshed with the second bevel gear 23. The driving motor 19 can drive the first bevel gear 21 to rotate through the round rod 20. After the first bevel gear 21 rotates, it can drive the second bevel gear 23 and the rotating rod 22 to rotate. After the rotating rod 22 rotates, it can drive the stirring arm 24 to stir the purified liquid in the purification box 2, thereby increasing the contact area between the purified liquid and the aerated smoke, improving the purification effect on the smoke, and avoiding the smoke from affecting the air environment after being discharged, with a better environmental protection effect.

[0025] Furthermore, the height of the bottom end of the conveying pipe 5 is higher than the height of the two sets of stirring arms 24. The conveying pipe 5 conveys the smoke into the purification box 2 without direct contact with the stirring arms 24, so it will not be affected by the stirring arms 24 during the smoke aeration process.

[0026] Furthermore, the width of the stirring arm 24 is smaller than the width of the inner wall of the purification box 2, and the stirring arm 24 will not collide with the inner wall of the purification box 2 during rotation, thereby ensuring that the purification box 2 can normally perform the purification function.

[0027] Working principle: First, the smoke generated in the incinerator will be attracted by the induced draft fan 3, enter the right-angle frame 9 through the dust collecting hood 11 and the right-angle tube 10, and will contact the blocking net 14. Large-volume impurities and debris in the smoke will be blocked by the blocking net 14 and fall onto the bottom plate 12 below, while small-particle impurities and smoke will enter the purification box 2 through the induced draft fan 3. The blocking net 14 can ensure that the smoke sucked in by the induced draft fan 3 will not contain large-volume impurities and debris, and ensure that the mechanical structure inside the induced draft fan 3 will not be damaged by the impact of such large-volume debris, which has a good protection effect on the induced draft fan 3. After entering the purification box 2, the smoke will directly contact the purification liquid in the purification box 2 through the conveying pipe 5. During the aeration operation, the driving motor 19 drives the first bevel gear 21 to rotate through the round rod 20, thereby driving the second bevel gear 23 and the rotating rod 22 to rotate, and driving the stirring arm 24 to stir the purified liquid to ensure that the contact area between the purified liquid and the aerated smoke is increased during the aeration process, thereby improving the purification effect of the smoke. After the aerated smoke contacts and reacts with the purified liquid, it moves upward in the purification box 2 and is finally discharged through the exhaust pipe 27. When it is on the inner wall of the exhaust pipe 27, it can be filtered twice through the activated carbon filter 28 before being discharged, further improving the environmental protection effect. In addition, the activated carbon filter 28 can be quickly removed through the internal threaded sleeve 25 and the external threaded connector 26, and has high flexibility.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
