[0002] In order to prevent waste generated during the combustion process from polluting the environment, existing incinerators usually introduce gas into a filtering device to purify the exhaust gas before discharging it.

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] See attached Figure 1 , Attachment Figure 4 and attached Figure 5 The embodiment of the utility model discloses an incinerator with dust removal, including a furnace body 1, a water cooling device 2, a spiral pipe 3, a water pump 4, and a filtering device 5. A furnace cavity 101 is provided inside the furnace body 1 for accommodating and incinerating articles. A plurality of furnace ports 102 communicating with the furnace cavity are provided on the side of the furnace body 1 for putting articles. A conveying pipe 6 communicating with the furnace cavity 101 is provided on the top of the furnace body 1; the interior of the water cooling device 2 is filled with coolant; the central axis of the spiral pipe 3 is substantially vertical and the input end 31 is higher than the output end 32, so that the fluid can always spiral along the extension direction of the spiral pipe 3. As it moves downward, the spiral pipe 3 is immersed in the coolant, the input end 31 is connected to the delivery pipe 6, and the output end 32 is connected to the water-gas dual-purpose pump 7, so that the high-temperature gas in the furnace chamber 101 can enter the delivery pipe 6 and the spiral pipe 3 in sequence under the suction action of the water-gas dual-purpose pump 7, and is continuously cooled down under the heat exchange action of the coolant; one end of the water pump 4 is inserted into the coolant, and the other end is connected to the input end 31 of the spiral pipe 3, which is used to flush the inner wall of the spiral pipe 3; the filter device 5 is connected to the water-gas dual-purpose pump 7, so that the cooled gas can enter the filter device 5 for dust removal and purification.

[0048] During actual use, the water-gas dual-purpose pump 7 is started, and the items are put into the furnace cavity 101 from the furnace port 102 on the side of the furnace body 1. The exhaust gas generated during the combustion process will enter the spiral pipe 3 through the conveying pipe 6. The exhaust gas will transfer heat to the spiral pipe 3 in the process of flowing from the input end 31 to the output end 32, and the coolant in the water cooling device 2 will exchange heat with the heated spiral pipe 3, thereby indirectly cooling the exhaust gas. The cooled exhaust gas will enter the filter device 5 through the water-gas dual-purpose pump 7, and will be discharged to the outside air after dust removal and purification by the filter device 5. When the inner wall of the spiral pipe 3 is contaminated with a lot of dirt, the water pump 4 can also be turned on to extract the coolant in the water cooling device 2 to flush the inner wall of the spiral pipe 3, so as to reduce the wall thickness of the spiral pipe 3 and increase the exhaust gas and heat exchange efficiency. and enables the exhaust gas to pass through the spiral pipe 3 more smoothly; since the exhaust gas is confined in the spiral pipe 3 with a significantly smaller diameter, the cross-sectional area of ​​the exhaust gas is smaller, the volume per unit length is smaller, and the cooling is significantly faster, and the coolant completely wraps the outer wall of the spiral pipe 3, so the exhaust gas can be cooled more evenly; since the coolant is not in direct contact with the exhaust gas, the coolant always remains clean and can be reused, which saves more water resources; since the spiral pipe 3 can be flushed by the coolant pumped by the water pump 4, and the water flow pumped out by the water pump 4 will obviously have a certain impact force, the inner wall of the spiral pipe 3 can be easily cleaned to prevent clogging; in general, by using the incinerator with dust removal, the cooling is more even and rapid, water resources are saved, and the spiral pipe can be effectively avoided from being blocked.

[0049] It should be noted that, since the output end 32 of the spiral pipe 3 is connected to the water-gas dual-purpose pump 7 , the coolant used to flush the spiral pipe 3 can also be discharged into the filter device 5 through the water-gas dual-purpose pump 7 .

[0050] It should be noted that the present application does not limit the size, length, material and other parameters of the spiral pipe 3, which can be flexibly selected according to actual needs. For example, the diameter of the spiral pipe 3 can be reduced or the length of the spiral pipe 3 can be extended to enhance the cooling effect. For example, the spiral pipe 3 can be made of a material that is resistant to high temperature, low temperature, and cold and heat changes, such as silicone, to extend its service life.

[0051] Furthermore, since the delivery pipe 6 cannot be flushed, the diameter of the delivery pipe 6 can be set to be larger to prevent blockage and facilitate gas suction.

[0052] See attached Figure 1 , Attachment Figure 3 and attached Figure 4In order to more clearly describe how the furnace body 1 is used, this embodiment introduces one design method of the furnace body 1. Specifically, the furnace body 1 is basically in the shape of a regular hexagonal prism, and there are six furnace openings 102, which are respectively arranged on the six sides of the furnace body 1. Six first through holes 8 are also provided at the bottom of the side of the furnace body 1. The six first through holes 8 are respectively provided to the six furnace openings 102. Each first through hole 8 is slidably connected to a waste slag box 9 for collecting waste slag. The cross-section of the waste slag box 9 is basically triangular, so that after the six waste slag boxes 9 are pushed into the six first through holes 8 respectively, they can basically fill the bottom of the furnace cavity 101.

[0053] Through the design of the above structure, one furnace body 1 can be used by multiple people at the same time. When there are a large number of people using it, the work efficiency is significantly improved. In addition, since there are six waste slag boxes 9 and they are respectively provided with six furnace openings 102, the waste slag boxes 9 that are full of waste slag can be taken out in a targeted manner. After taking out one, it will not affect the normal use of other waste slag boxes 9 and the furnace openings 102 corresponding to other waste slag boxes 9, so that the furnace body 1 can continue to work, and the waste slag stored in one waste slag box 9 only accounts for one-sixth of the maximum waste slag capacity that the furnace body 1 can store. Moving, transporting and subsequent cleaning are easier and more labor-saving, and more convenient to use.

[0054] See attached Figure 1 -Attached Figure 3 In order to prevent the six furnace openings 102 from being always open, causing foreign matter to enter the furnace cavity 101, the following design is implemented in this embodiment. Specifically, it also includes a furnace door 10 and a plurality of second through holes 11. The furnace door 10 is slidably connected to the furnace body 1 and is arranged corresponding to the furnace openings 102 for opening and closing the furnace openings 102; the plurality of second through holes 11 are all arranged on the furnace body 1 and corresponding to the furnace door 10, so that when the furnace openings 102 are opened, the plurality of second through holes 11 are shielded by the furnace door 10, and when the furnace openings 102 are closed, the plurality of second through holes 11 are exposed, so that external gas can enter the furnace cavity 101, so that the items in the furnace cavity 101 remain in a burning state.

[0055] Through the design of the above structure, when the furnace mouth 102 is not in use, it can be temporarily closed through the furnace door 10 to prevent foreign matter from entering the furnace cavity 101. After closing the furnace mouth 102, the corresponding multiple second through holes 11 will be exposed to prevent external gas from entering the furnace cavity 101, resulting in oxygen depletion in the furnace cavity 101 and failure to burn. That is, regardless of whether the furnace mouth 102 is closed or whether it is completely closed, the items in the furnace cavity 101 can burn normally.

[0056] See attached Figure 1 and attached Figure 5There are many structures that can achieve water cooling effect. This embodiment introduces one of them. Specifically, the water cooling device 2 includes a first box body 21 and a water cooler 22. The coolant is filled inside the first box body 21; the water inlet end 221 and the water outlet end 222 of the water cooler 22 are both connected to the first box body 21, and the height of the water inlet end 221 is lower than the height of the upper surface of the coolant.

[0057] Through the design of the above structure, the coolant can circulate between the first box 21 and the water cooler 22, and the temperature is reduced after flowing through the water cooler 22; it has the advantages of simple structure and reliable operation.

[0058] See attached Figure 5 and attached Figure 6 Based on the above scheme, after the water cooling device 2 has been working for a period of time, the temperature at the water inlet end 221 of the water cooler 22 is significantly higher than the temperature at the water outlet end 222, and the fluid circulation process is relatively stable. The water bodies in different areas are not easy to mix with each other, resulting in uneven temperature distribution of the water bodies in different areas, which makes the cooling efficiency of different parts of the spiral pipe 3 different. In order to solve the above problem, the following design is made in this embodiment. Specifically, it also includes a stirring component 23, which is arranged on the first box body 21 and is used to stir the coolant to accelerate the heat exchange speed. The stirring component 23 includes a motor 231, a rotating shaft 232, and multiple groups of first stirring rods 233. The motor 231 is fixedly connected to the top of the first box body 21; one end of the rotating shaft 232 is driven and connected to the motor 231, and the other end opposite to it is located in the coolant; the multiple groups of first stirring rods 233 are all arranged on the rotating shaft 232, and each group of first stirring rods 233 is composed of multiple first stirring rods 233 located in the same plane. The multiple groups of first stirring rods 233 are linearly arranged along the extension direction of the rotating shaft 232.

[0059] Through the design of the above structure, the motor 231 can be started, and the rotating shaft 232 drives the multiple first stirring rods 233 to rotate, thereby stirring and mixing the coolant in different areas, making the temperature distribution of the coolant more uniform, and allowing the temperature of the exhaust gas to basically maintain a uniform decline.

[0060] See attached Figure 7 Based on the above solution, the stirring action of the first stirring rod 233 can accelerate the mixing of the coolant in different areas, but since the stirring direction remains unchanged, vortexes are easily formed. The vortex is also a relatively stable flow state, which makes it difficult for the coolant in different areas to mix easily, and the improvement in heat exchange efficiency is not obvious enough. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, each first stirring rod 233 is rotatably connected to a second stirring rod 234. The plane formed by the second stirring rod 234 when rotating is perpendicular to the extension direction of the first stirring rod 233, which is used to disturb the liquid.

[0061] Through the design of the above structure, since the second stirring rod 234 is rotatably connected to the first stirring rod 233, while the first stirring rod 233 stirs the water, the second stirring rod 234 will also stir in different directions, making the orderly flowing water body become chaotic and disordered, and the coolants in different areas are more likely to collide, impact and mix. At the same time, these coolants will also increase the heat exchange efficiency in the process of colliding and impacting the spiral pipe 3.

[0062] See attached Figure 1 , Attachment Figure 8 and attached Figure 9 There are many structures that can achieve a filtering effect, and one of them is introduced in this embodiment. Specifically, the filtering device 5 includes a second box body 51 and three frames 52. The upper part of the second box body 51 is connected to the water-gas dual-purpose pump 7, and the lower part of the second box body 51 is provided with a discharge pipe 511. The side of the second box body 51 is provided with three third through holes 53. The three third through holes 53 are arranged linearly in the vertical direction, and the height of the topmost third through hole 53 is lower than the height of the connection part between the second box body 51 and the water-gas dual-purpose pump 7, and the height of the bottommost third through hole 53 is higher than the height of the discharge pipe 511; the three frames 52 are respectively detachably connected to the three third through holes 53 to prevent gas from leaking from the third through holes 53. From top to bottom, the middle parts of the three frames 52 are provided with a primary filter 54, a medium-efficiency filter 55 and a high-efficiency filter 56 in sequence.

[0063] Through the design of the above structure, multi-stage filtration of exhaust gas can be achieved, which greatly delays the time for the filter device 5 to be blocked and greatly improves the degree of purification. When there are too many impurities on a certain filter net, it can be taken out and replaced, which is convenient and quick to use.

[0064] It should be noted that, based on the above scheme, after the coolant for flushing the spiral pipe 3 is discharged into the filter device 5 through the water-gas dual-purpose pump 7, the primary filter 54, the medium-efficiency filter 55 and the high-efficiency filter 56 can also be flushed, thereby effectively preventing blockage. The waste water generated subsequently can also be discharged from the second box 51 through the discharge pipe 511 after filtration.

[0065] The exhaust gas produced by combustion contains not only dust, but also impurities such as hydrocarbons, sulfides, dioxins, PN2.5, etc. Some of these impurities are not only small in size and difficult to filter, but also have odors, and are difficult to effectively purify using a filter alone. In order to solve the above problems, the following design is made in this embodiment. Specifically, activated carbon particles are sprinkled on the upper parts of the primary filter 54, the medium-efficiency filter 55 and the high-efficiency filter 56.

[0066] Through the design of the above structure, when the exhaust gas passes through the primary filter 54, the medium efficiency filter 55 and the high efficiency filter 56, a part of the impurities will be adsorbed on the activated carbon particles, which can effectively enhance the purification effect and remove odor.

[0067] It should be noted that, since activated carbon is a common existing technology, the working principle of activated carbon will not be described in detail here, nor will it be shown in the accompanying drawings.

[0068] See attached Figure 1 and attached Figure 3 Since the water pump 4 cannot control the flow direction of the coolant after pumping it into the spiral pipe 3, and the coolant pumped in by the water pump 4 carries a certain impact force, the coolant may move toward the direction of the delivery pipe 6, or even enter the furnace chamber 101, causing the fire to go out. In order to avoid the above situation, the following design is made in this embodiment. Specifically, it also includes a first one-way valve 12. The first one-way valve 12 is arranged on the delivery pipe 6 so that the fluid can only flow from the furnace chamber 101 to the spiral pipe 3.

[0069] Through the design of the above structure, the coolant can be effectively prevented from entering the furnace cavity 101. Even if the pressure and impact force of the coolant entering the spiral pipe 3 are large, it will not affect the combustion of the items in the furnace cavity 101. On the contrary, it will make the inner wall of the spiral pipe 3 more clean.

[0070] See attached Figure 5 If the water pump 4 is directly connected to the spiral pipe 3, the exhaust gas will directly contact the coolant. If some impurities in the exhaust gas are soluble in water, the coolant will be polluted. In addition, if the air pressure in the spiral pipe 3 is too high, the exhaust gas may even backflow to the water pump 4 and enter the water cooling device 3, and then be directly discharged to the outside, causing air pollution. In order to avoid the above situation, the following design is carried out in this embodiment. Specifically, it also includes a second one-way valve 13. The second one-way valve 13 is arranged between the water pump 4 and the spiral pipe 3 so that the fluid can only flow from the water pump 4 to the spiral pipe 3.

[0071] The above structural design can effectively prevent the exhaust gas from directly contacting the coolant, so that the exhaust gas can only be discharged to the outside after being cooled and filtered in sequence, which is safer and more reliable.
