Description

Technical Field

[0001] This utility model relates to the field of incineration equipment technology, and in particular to an incinerator. Background Technology

[0002] Combustion is currently a relatively mature, stable, and effective end-of-pipe treatment technology for organic waste gas. The principle is to burn and oxidize volatile organic compounds (VOCs, also known as organic waste gas) into water and carbon dioxide at high temperatures.

[0003] Traditional incinerators for VOCs waste gas treatment require high-calorific-value gases as auxiliary fuels to stabilize the furnace temperature and provide the necessary conditions for the thermal decomposition of VOCs. Furthermore, to ensure complete VOCs reaction, the furnace volume is relatively large. This results in a lengthy preheating process of the large furnace cavity during the initial stages of incineration, requiring a significant amount of high-calorific-value fuel gas and leading to high operating costs. Additionally, the incinerator is typically encased in a thick insulation layer to maintain temperature stability and prevent burns to workers, further increasing the overall size of the incinerator and raising equipment costs and floor space requirements.

[0004] Therefore, there is an urgent need to develop an incinerator to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides an incinerator that integrates a flue gas flow channel and a combustion-supporting gas flow channel on the furnace body, enabling the combustion-supporting gas to cool the flue gas, eliminating the need for a heat exchanger, reducing component costs, and also making the overall size of the incinerator smaller.

[0006] To achieve this objective, the present invention adopts the following technical solution:

The second chamber has an independent combustion-supporting gas flow channel and a flue gas flow channel. The flue gas flow channel and the combustion-supporting gas flow channel have a complementary serpentine nested structure. The inlet of the flue gas flow channel is connected to the outlet of the first chamber. The outer wall of the furnace body has a flue gas outlet connected to the outlet of the flue gas flow channel and a first combustion-supporting gas inlet connected to the inlet of the combustion-supporting gas flow channel.

[0009] A burner is disposed on the furnace body. The burner includes a second combustion gas inlet and a combustion chamber. The combustion chamber is located at the inlet of the first chamber. The second combustion gas inlet is connected to the outlet of the combustion gas flow channel.

[0010] Optionally, the outermost combustion-supporting flow channel is adjacent to the outer wall of the furnace body, and the innermost flue gas flow channel is in close contact with the first chamber.

[0011] Optionally, the second chamber is provided with a partition with a serpentine axial cross-section, and the combustion-supporting gas flow channel and the flue gas flow channel are respectively located on both sides of the partition, and the combustion-supporting gas and the flue gas exchange heat through the partition.

[0012] Optionally, the partition includes a plurality of partition plates spaced apart along the radial direction of the second chamber. The partition plates have gaps between themselves and the first and second walls of the second chamber. The first and second walls are arranged opposite to each other along the axial direction of the second chamber. The first wall is close to the burner, and the second wall is close to the outlet of the first chamber.

[0013] Each of the partition plates is connected to a connecting plate extending radially along the second chamber at both ends in the axial direction. The connecting plates at both ends of the same partition plate extend in opposite directions. Adjacent partition plates are connected by the same connecting plate. The partition plate near the outer wall of the first chamber is connected to the outer wall of the first chamber by the connecting plate. The connecting plate and the first wall form the outlet of the combustion-supporting flow channel. The partition plate near the outer wall of the furnace body is connected to the outer wall of the furnace body by the connecting plate. The connecting plate and the second wall form the outlet of the flue gas flow channel.

[0014] Each connecting plate away from the first wall is provided with a first baffle plate. One end of the first baffle plate is connected to the first wall, and the other end has a gap with the corresponding connecting plate. The combustion gas flows back and forth between two adjacent partition plates through the first baffle plate. Each connecting plate away from the second wall is provided with a second baffle plate. One end of the second baffle plate is connected to the second wall, and the other end has a gap with the corresponding connecting plate. The combustion gas flows back and forth between two adjacent partition plates through the second baffle plate.

[0015] Optionally, the partition plate, the first baffle plate, and the second baffle plate are each provided with a plurality of support bars, which extend along the flow direction of the combustion-supporting gas or the flue gas.

[0019] Optionally, the furnace body is also provided with an explosion-proof pressure relief valve, which is located near the outlet of the first chamber.

[0020] Optionally, the burner is an infrared burner.

[0021] The beneficial effects of this utility model are:

[0022] This invention provides an incinerator, including a furnace body and a burner. The furnace body has a first chamber and a second chamber surrounding the outer periphery of the first chamber. The second chamber contains independent combustion-supporting gas channels and flue gas channels, which are arranged in a complementary serpentine nested structure. This arrangement causes the outlines of the flue gas channels and combustion-supporting gas channels to periodically intersect, forming a spatially intertwined heat exchange surface. Low-temperature combustion-supporting gas enters the combustion-supporting gas channels through the first combustion-supporting gas inlet on the furnace body, and is guided by the combustion-supporting gas channels before finally entering the burner through the second combustion-supporting gas inlet on the burner for combustion. Combustion in the burner preheats the first chamber. Organic waste gas decomposes in the first chamber, forming hot flue gas that enters the flue gas channels and is then guided by the flue gas channels before finally exiting from the flue gas outlet of the furnace body. The low-temperature combustion-supporting gas in the combustion-supporting gas channels and the flue gas in the flue gas channels can exchange heat; that is, the low-temperature combustion-supporting gas in the combustion-supporting gas channels acts as a "heat exchanger," eliminating the need for an additional heat exchanger in the incinerator and reducing component costs. At the same time, the temperature rise of the auxiliary gas after heat exchange is also conducive to the complete combustion of the auxiliary gas in the burner.

[0023] The combustion gas flow channel and flue gas flow channel feature a complementary serpentine nested structure, increasing the flow path and time of the combustion gas and flue gas, which is more conducive to sufficient heat exchange between them. Furthermore, along the radial direction of the furnace body, the temperature of the flue gas gradually decreases from the inside to the outside, while the temperature of the combustion gas gradually increases from the outside to the inside. Specifically, near the first chamber, both the flue gas and combustion gas temperatures are higher, providing insulation for the first chamber; further away from the first chamber, both temperatures are lower, providing insulation and preventing burns to personnel from excessively high furnace exterior temperatures. This also eliminates the need for additional insulation cotton around the furnace exterior, reducing equipment costs. Moreover, compared to existing technologies that use insulation cotton, the insulation layer formed by the low-temperature combustion gas and flue gas is thinner, reducing the overall size of the incinerator.

[0024] In addition, the flue gas temperature is higher in the flue gas duct near the first chamber, and the undecomposed organic waste gas can continue to decompose in this section of the flue gas duct, which is equivalent to folding and expanding the first chamber, further reducing the overall size of the incinerator.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] This embodiment provides an incinerator that integrates a flue gas flow channel and a combustion-supporting gas flow channel on the furnace body, enabling the combustion-supporting gas to cool the flue gas, eliminating the need for a heat exchanger, reducing component costs, and also making the overall size of the incinerator smaller.

[0041] Specifically, such as Figures 1-3 As shown, the incinerator includes a furnace body 100 and a burner 200.

[0042] The furnace body 100 includes a first chamber 110 and a second chamber 120 surrounding the first chamber 110. Organic waste gas is primarily decomposed within the first chamber 110. The second chamber 120 contains an independent combustion-supporting gas flow channel 121 and a flue gas flow channel 122. The flue gas flow channel 122 and the combustion-supporting gas flow channel 121 form a complementary serpentine nested structure. The inlet of the flue gas flow channel 122 is connected to the outlet of the first chamber 110. The outer wall of the furnace body 100 has a first combustion-supporting gas inlet 140 connected to the inlet of the combustion-supporting gas flow channel 121 and a flue gas outlet 130 connected to the outlet of the flue gas flow channel 122.

[0043] The burner 200 is installed on the furnace body 100. The burner 200 includes a second auxiliary gas inlet 210 and a combustion chamber 220. The combustion chamber 220 is located at the inlet of the first chamber 110. The second auxiliary gas inlet 210 is connected to the outlet of the auxiliary gas flow channel 121.

[0044] Figure 3 Solid arrows indicate the flow direction of flue gas, while hollow arrows indicate the flow direction of combustion-supporting gas. In the axial section of the furnace body 100, both flue gas and combustion-supporting gas flow in a serpentine, meandering pattern along the axial direction of the second chamber 120. In this embodiment, the high-temperature flue gas generated after the decomposition of organic waste gas in the first chamber 110 enters the flue gas flow channel 122 and, guided by the flue gas flow channel 122, is finally discharged from the flue gas outlet 130. Low-temperature combustion-supporting gas enters the combustion-supporting gas flow channel 121 from the first combustion-supporting gas inlet 140 and, guided by the combustion-supporting gas flow channel 121, enters the burner 200 to participate in combustion.

[0045] Because the flue gas flow channel 122 and the combustion gas flow channel 121 have a complementary serpentine nested structure, their outlines periodically intersect, forming a spatially intertwined heat exchange interface. Therefore, the low-temperature combustion gas in the combustion gas flow channel 121 and the flue gas in the flue gas flow channel 122 can exchange heat. In other words, the low-temperature combustion gas in the combustion gas flow channel 121 acts as a "heat exchanger," eliminating the need for an additional heat exchanger in the incinerator and reducing component costs. Simultaneously, the increased temperature of the combustion gas after heat exchange also facilitates complete combustion of the auxiliary gas within the burner 200.

[0046] The structure of the combustion-supporting gas flow channel 121 and the flue gas flow channel 122 also increases the flow path and flow time of the combustion-supporting gas and the flue gas, which is more conducive to the full heat exchange between the combustion-supporting gas and the flue gas. Furthermore, along the radial direction of the furnace body 100, the temperature of the flue gas gradually decreases from the inside to the outside, while the temperature of the combustion-supporting gas gradually increases from the outside to the inside. That is, near the first chamber 110, the temperature of both the flue gas and the combustion-supporting gas is higher, which can play a role in heat preservation of the first chamber 110. Far away from the first chamber 110, the temperature of both the flue gas and the combustion-supporting gas is lower, which can play a role in heat insulation. This prevents the outer wall of the furnace body 100 from being too hot and burning the staff. It also means that there is no need to wrap the outer perimeter of the furnace body 100 with additional heat insulation cotton, thus reducing equipment costs.

[0047] Because the flue gas temperature is high in the flue gas duct 122 near the first chamber 110, the undecomposed organic waste gas can continue to decompose in this section of the flue gas duct 122. Therefore, this section of the flue gas duct 122 is equivalent to expanding the first chamber 110, and the expansion is in a folded manner. Compared with the incinerator with the same organic waste gas treatment capacity in the prior art, the volume is reduced by at least one-third.

[0048] Compared with the existing technology of setting thermal insulation cotton, the insulation layer formed by low-temperature combustion and flue gas is thinner. Therefore, the insulation layer formed by low-temperature combustion and flue gas can significantly reduce the overall size of the incinerator while ensuring the insulation effect.

[0049] For example, with 200m 3 Taking a processing capacity of / h as an example, with the furnace cross-sectional area remaining unchanged, the dimensions of the traditional incinerator body 100 are 950mm × 950mm. To ensure the residence time of organic waste gas within the furnace, the furnace body 100 is approximately 3.5m high, and the thickness of the insulation layer on one side is 320mm-400mm. The incinerator provided in this embodiment has dimensions of 786mm × 786mm, a furnace body 100 height of approximately 1.2m, and a second chamber 120 thickness of approximately 200mm, significantly reducing the floor space required.

[0050] Furthermore, the outermost combustion-supporting gas flow channel 121 is adjacent to the outer wall of the furnace body 100. This arrangement results in the lowest temperature at the outer wall of the furnace body 100 and the best heat insulation effect. In addition, the innermost flue gas flow channel 122 is in close contact with the first chamber 110. This arrangement provides the best heat preservation effect for the first chamber 110.

[0051] Optionally, the total volume of the flue gas duct 122 can be set to be 2 to 3 times the volume of the first chamber 110. This setting is beneficial for increasing the volume of the furnace body 100 without making the overall size of the furnace body 100 too large.

[0052] Furthermore, such as Figure 3 and Figure 4 As shown, the second chamber 120 is provided with a partition 150 with a serpentine axial cross-section. The combustion-supporting gas flow channel 121 and the flue gas flow channel 122 are respectively located on both sides of the partition 150, and the combustion-supporting gas and the flue gas exchange heat through the partition 150. That is, the partition 150 is a shared wall surface of the combustion-supporting gas flow channel 121 and the flue gas flow channel 122. This arrangement results in better heat exchange. In this embodiment, the flue gas flows outward from the first chamber 110, and the combustion-supporting gas flows inward from the outside into the first chamber 110. That is, the overall flow direction of the flue gas and the combustion-supporting gas is opposite, which further facilitates heat exchange.

[0053] Understandably, the area of ​​the separator 150 can be set based on the desired heat exchange effect. In one possible embodiment, the area of ​​the separator 150 is such that the temperature of the combustion gas entering the burner 200 after heat exchange is 200°C-300°C. This setting allows for the recovery of some heat while preventing excessively high manufacturing costs due to an excessively large area of ​​the separator 150.

[0054] Furthermore, such as Figure 3 and Figure 6As shown, the partition 150 includes a plurality of partition plates 151 spaced apart along the radial direction of the second chamber 120. There are gaps between the partition plates 151 and the first wall surface 123 and the second wall surface 124 of the second chamber 120. The first wall surface 123 and the second wall surface 124 are arranged opposite to each other along the axial direction of the second chamber 120. The first wall surface 123 is close to the burner 200, and the second wall surface 124 is close to the outlet of the first chamber 110. Each partition plate 151 has a connecting plate 152 extending radially along the second chamber 120 at both ends in the axial direction. The connecting plates 152 at both ends of the same partition plate 151 extend in opposite directions. Adjacent partition plates 151 are connected by the same connecting plate 152. The partition plate 151 near the outer wall of the first chamber 110 is connected to the outer wall of the first chamber 110 through the connecting plate 152. The connecting plate 152 and the first wall surface 123 form the outlet of the combustion-supporting flow channel 121. The partition plate 151 near the outer wall of the furnace body 100 is connected to the outer wall of the furnace body 100 through the connecting plate 152. The connecting plate 152 and the second wall surface 124 form the outlet of the flue gas flow channel 122. This partition 150 has a simple structure and is easy to assemble.

[0055] Each connecting plate 152 away from the first wall 123 is provided with a corresponding first baffle 160. One end of the first baffle 160 is connected to the first wall 123, and the other end has a gap with its corresponding connecting plate 152. The combustion gas flows back and forth between two adjacent partition plates 151 through the first baffle 160. Each connecting plate 152 away from the second wall 124 is provided with a corresponding second baffle 170. One end of the second baffle 170 is connected to the second wall 124, and the other end has a gap with its corresponding connecting plate 152. The combustion gas flows back and forth between two adjacent partition plates 151 through the second baffle 170. That is, through the cooperation of the partition 150, the first baffle 160 and the second baffle 170, the combustion gas flow channel 121 and the combustion gas flow channel form a complementary serpentine nested structure. This arrangement is simple in structure, easy to assemble, and has a better heat exchange effect.

[0056] Furthermore, such as Figure 4 and Figure 6 As shown, the partition plate 151, the first baffle plate 160, and the second baffle plate 170 are all provided with multiple support bars 153, which extend along the flow direction of the combustion gas or flue gas. By providing support bars 153, on the one hand, the strength of the partition plate 151, the first baffle plate 160, and the second baffle plate 170 can be improved; on the other hand, the heat exchange area of ​​the partition plate 151 can be increased, thereby improving the heat exchange effect between the combustion gas and the flue gas.

[0057] Optionally, see [link to relevant documentation] Figure 6The support bar 153 can be set with a small gap with the adjacent plate, so that it can support the adjacent plate and provide flexible space for thermal expansion.

[0058] For example, if the plate adjacent to the support strip 153 disposed on the partition plate 151 is the first deflector plate 160, then the gap between the end of the support strip 153 away from the partition plate 151 and the first deflector plate 160 is small or there is no gap, so as to support the first deflector plate 160.

[0059] Optionally, see [link to relevant documentation] Figure 1 , Figure 2 , Figure 5 and Figure 6 The incinerator also includes a mounting frame 300, on which the furnace body 100 is horizontally fixed; or, the furnace body 100 is vertically fixed. By setting up the mounting frame 300, a suitable fixing method for the furnace body 100 can be selected according to the site, which helps to meet various user needs.

[0060] Optionally, see [link to relevant documentation] Figure 2 In one possible embodiment, the burner 200 further includes a gas inlet 230 through which gas enters the combustion chamber 220 to participate in combustion and preheat the first chamber 110. The organic waste gas to be treated enters the burner 200 through the gas inlet 230 and is discharged from the combustion chamber 220 into the first chamber 110 for decomposition. That is, the organic waste gas needs to pass through the burner 200 before entering the first chamber 110. During the flow of the organic waste gas through the burner 200, the burner 200 preheats the organic waste gas, thereby shortening the decomposition time, reducing fuel consumption, and lowering the treatment cost. Simultaneously, the elimination of a preheating device for the organic waste gas reduces component costs and also helps to reduce the overall size of the incinerator.

[0061] Alternatively, in other possible embodiments, a separate exhaust gas inlet communicating with the first chamber 110 may be provided on the furnace body 100, so that organic waste gas enters the first chamber 110 through the exhaust gas inlet for decomposition.

[0062] Optionally, the burner 200 can be an infrared burner. Infrared burners utilize the high temperatures generated by gas combustion and release the heat primarily in the form of infrared radiation through a specially designed radiant plate (usually a porous ceramic plate, metal fiber mesh, or metal plate). This heat transfer method (primarily radiation) offers advantages such as rapid heating, uniform heating, energy saving, and environmental friendliness.

[0063] Optionally, the furnace body 100 is also equipped with an explosion-proof pressure relief valve, which is located near the outlet of the first chamber 110. By installing the explosion-proof pressure relief valve, in the event of an internal explosion in the incinerator, the overpressure can be released quickly to protect the incinerator and personnel, and reduce accident losses.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
