Regenerative combustion device

Abstract

The application relates to the technical field of waste gas treatment, in particular to a regenerative combustion device. In the embodiment of the application, all the heat accumulators in the same heat accumulation area are arranged at intervals to form interval channels. When part of the area in the heat accumulator is blocked, the gas can flow into the corresponding interval channel through other areas of the heat accumulator and be redistributed to the adjacent heat accumulator, thereby improving the airflow blockage of the adjacent heat accumulator caused by the local blockage of the heat accumulator, and effectively reducing the gas operation resistance fluctuation caused by the blockage. Since the heat accumulators closer to the combustion area are more prone to blockage, by arranging at least one interval channel in at least one heat accumulation area closer to the combustion area, the situation of the gas operation resistance fluctuation caused by the blockage can be further improved. Therefore, the regenerative combustion device provided by the embodiment of the application can improve the operation stability of the regenerative combustion device.

Description

Technical Field

[0001] This application relates to the field of waste gas treatment technology, and in particular to regenerative thermal combustion devices. Background Technology

[0002] Currently, in the treatment of waste gas, heat can be recycled through the heat storage medium in a regenerative combustion device, effectively reducing energy consumption. As the core component of the regenerative combustion device, the heat storage medium plays a crucial role in the preheating of waste gas and the recovery of heat from purified gas; its performance directly affects the operating efficiency and treatment effect of the regenerative combustion device. However, in actual use, the heat storage medium is prone to blockage, thus restricting the stable operation of the regenerative combustion device. Utility Model Content

[0003] Based on this, this application provides a regenerative combustion device to improve the operational stability of the regenerative combustion device.

[0004] This application provides a regenerative combustion device, including a main body and a plurality of heat storage bodies. The main body has a receiving cavity, which includes a combustion zone and a plurality of heat storage zones, each connected to the combustion zone. The combustion zone is located on the top side of the plurality of heat storage zones, and the heat storage zones are provided with a plurality of heat storage bodies. Within the same heat storage zone, all heat storage bodies are spaced apart along the direction from the top side of the main body to the bottom side of the main body, with a spacer channel defining a spacer between two adjacent heat storage bodies. Each heat storage zone has a target area located between the top side of the main body and a reference surface. Within the same heat storage zone, at least one spacer channel is located within the target area of ​​the heat storage zone. The reference surface is perpendicular to the direction from the top side of the main body to the bottom side of the main body, and the heat storage zone has a central axis perpendicular to the direction from the top side of the main body to the bottom side of the main body, with the central axis located on the reference surface.

[0005] In the technical solution of this application embodiment, all heat storage bodies within the same heat storage area are arranged at intervals to form interval channels. When a part of a heat storage body becomes blocked, the gas can flow through other areas of that heat storage body to the corresponding interval channel and be redistributed to adjacent heat storage bodies. This improves the airflow obstruction to adjacent heat storage bodies caused by local blockage, thereby effectively reducing gas flow resistance fluctuations caused by blockage. Since heat storage bodies closer to the combustion area are more prone to blockage, by setting at least one interval channel within at least one heat storage area closer to the combustion area, the gas flow resistance fluctuation caused by blockage can be further improved. Therefore, the regenerative combustion device provided in this application embodiment can improve the operational stability of the regenerative combustion device. Furthermore, compared to all heat storage bodies within the same heat storage area being arranged sequentially adjacent to each other, the interval channels in this application embodiment help reduce the risk that all channels in the direction from the top side of the body to the bottom side of the body will be blocked due to local blockage, thereby extending the replacement cycle of the corresponding heat storage body and facilitating the maintenance of the regenerative combustion device.

[0006] In some embodiments, at least three heat storage elements are provided in at least one heat storage region. Within a heat storage region with at least three heat storage elements, the height of all heat storage elements increases in a direction from the top side to the bottom side of the body. The height of a heat storage element is the dimension of the heat storage element in the direction from the top side to the bottom side of the body.

[0007] When exhaust gas flows from the top to the bottom of the main body, impurities such as solid particles carried by the exhaust are more likely to deposit on the heat storage body closer to the top of the main body. By configuring the height of all heat storage bodies in a heat storage region with at least three heat storage bodies in an increasing trend, the volume of the heat storage body closer to the top of the main body can be set to be smaller. Therefore, even if the heat storage body closer to the top of the main body is partially blocked, the exhaust gas can pass through the partially blocked heat storage body more quickly from the top to the bottom of the main body and be redistributed to the adjacent heat storage bodies through the corresponding interval channels. This can further effectively reduce the fluctuation of gas running resistance caused by blockage.

[0008] In some embodiments, within a heat storage region having at least three heat storage bodies, the height of all heat storage bodies increases sequentially in the direction from the top side of the body to the bottom side of the body.

[0009] By configuring the height of all heat storage bodies in a heat storage region with at least three heat storage bodies to increase sequentially, the height of the heat storage bodies is roughly increased, forming a stepped structure. This allows the exhaust gas to pass through the heat storage bodies that are more prone to clogging more quickly, thereby further reducing the impact of clogging on gas flow after the heat storage bodies with a high risk of clogging become blocked.

[0010] In some embodiments, all heat storage elements have the same height along the direction from the top side to the bottom side of the body. The height of the heat storage element is the dimension of the heat storage element along the direction from the top side to the bottom side of the body.

[0011] This not only makes the overall structure simpler, easier to manufacture and maintain, but also makes the airflow distribution more uniform.

[0012] In some embodiments, at least three heat storage bodies are provided in at least one heat storage region, and at least two spacer channels are provided in the at least one heat storage region. In a heat storage region with at least two spacer channels, all spacer channels have the same size in the direction from the top side of the body to the bottom side of the body.

[0013] This makes the structure and spacing channels formed by the heat storage body in the corresponding heat storage area more regular, which not only helps to improve the uniformity of airflow distribution and control the pressure drop of airflow, but also helps to improve the stability of heat exchange efficiency of the heat storage body and the uniformity of temperature field in the heat storage area.

[0014] In some embodiments, the regenerative combustion device further includes multiple pull-out components, each corresponding to a different heat storage element. The pull-out components support the corresponding heat storage element and engage with the main body during pulling.

[0015] Thus, when the corresponding heat storage element needs to be replaced, the heat storage element can be pulled out of the main body using the pull-out component, allowing the operator to replace it. This reduces the difficulty and safety risks of replacement and improves the comfort of the working environment. Furthermore, since all heat storage elements can be pulled out individually, only the element requiring replacement can be operated on separately, making the maintenance process more flexible and convenient.

[0016] In some embodiments, the regenerative combustion device further includes multiple fixing components, which are respectively arranged one-to-one with multiple pull-out components. The fixing components are used to detachably fix the corresponding pull-out component and the main body.

[0017] Thus, by setting up a fixing component, the pull-out component and the main body can be fixedly connected when the pull-out component is inserted into the main body. When it is necessary to pull the pull-out component out of the main body, the fixing component can be opened to separate the pull-out component from the main body, making it easy to remove the pull-out component. This facilitates more convenient and efficient maintenance and replacement of the pull-out component, as well as more flexible modular expansion and adjustment.

[0018] In some embodiments, the pull-out member includes a support portion for supporting the heat storage body, the support portion having multiple through holes extending through the support portion in a direction from the top side of the body to the bottom side of the body. The heat storage body has multiple vent holes, the minimum diameter of which is larger than the maximum diameter of which is vent hole.

[0019] Thus, by setting up a support unit, it is not only easier to support the heat storage body more stably and conveniently, but also to connect the vent holes of the heat storage body and the corresponding interval channels through the through holes, thereby facilitating the flow of exhaust gas within the heat storage area.

[0020] In some embodiments, the regenerative combustion device further includes a plurality of sliding components, which are correspondingly arranged with a plurality of pull-out members. The sliding components are engaged between the corresponding pull-out members and the main body, so that the pull-out members are slidably connected to the main body.

[0021] Thus, by setting up a sliding component, the pull-out part can be pulled out or inserted relative to the main body by sliding, thereby improving operational flexibility, maintenance convenience and structural reliability.

[0022] In some embodiments, the heat storage body has multiple vent holes. Within the same heat storage region, the minimum diameter of the vent holes of all heat storage bodies tends to increase along the direction from the top side of the body to the bottom side of the body.

[0023] Thus, by making the vent holes of the heat storage element closer to the top of the body relatively smaller, the time it takes for exhaust gas to pass through the heat storage element closer to the body can be extended, allowing the heat storage element closer to the body to accumulate more heat, thereby improving the heat storage effect. By making the vent holes of the heat storage element closer to the bottom of the body relatively larger, the gas resistance of exhaust gas passing through the heat storage element closer to the bottom of the body can be reduced, thereby improving the stability of the total gas volume, and further improving the operational stability of the regenerative combustion device.

[0024] In some embodiments, within the same heat storage area, the minimum aperture of the vent holes of all heat storage bodies increases sequentially in the direction from the top side of the body to the bottom side of the body.

[0025] Thus, a gradient design of the vents can be achieved in the heat storage area along the direction from the top to the bottom of the main body. This improves the heat exchange effect between the exhaust gas and the heat storage medium near the top of the main body, while reducing gas resistance near the bottom. This combination of improved heat exchange and reduced gas resistance enhances the overall treatment efficiency of the regenerative combustion device. Furthermore, since exhaust gas is more prone to coking in the heat storage medium near the top and more prone to ash formation in the heat storage volume near the bottom, different vent diameters for the top and bottom of the main body allow for differentiated maintenance of the heat storage medium in different areas, thereby reducing maintenance costs.

[0026] In some embodiments, all heat storage elements located in the same heat storage area constitute a heat storage element group. All heat storage element groups are arranged along a first direction. The first direction is perpendicular to the direction from the top side of the body to the bottom side of the body.

[0027] In this way, by controlling the arrangement of the thermal storage units, it is not only easier to install and maintain, but also easier to control different thermal storage units separately, thereby improving processing efficiency and flexibility.

[0061] Regenerative Thermal Oxidizers (RTOs) are crucial components of exhaust gas treatment systems. Taking an RTO as an example, an RTO is a highly efficient and environmentally friendly device for treating VOCs (volatile organic compounds). The main working principle of an RTO is to heat the exhaust gas to above 760°C (or another required temperature). At this temperature, the VOCs in the exhaust gas undergo a chemical reaction, breaking down into environmentally friendly gases such as carbon dioxide and water, thus reducing environmental harm. RTOs typically incorporate a heat storage medium to achieve heat recycling and effectively reduce energy consumption. Before being discharged at high temperatures, the combusted exhaust gas passes through a porous heat storage medium, exchanging heat with it and transferring heat to the medium, allowing the exhaust gas to be discharged outdoors at a lower temperature. When fresh air enters the RTO, it first absorbs the heat stored in the heat storage medium, heating it to a higher temperature, and then further heated to 760°C (or another required temperature) by the fuel gas, thus reducing energy waste.

[0062] However, when treating waste gas containing silicon, the combustion of this silicon gas produces not only carbon dioxide and water, but also solid silica. This solid silica can adhere to the pores of the heat storage medium, causing blockages. This impairs normal gas flow and heat exchange, causing the RTO (Regenerative Thermal Oxidizer) to deviate from its operating conditions and thus hindering the stable operation of the regenerative combustion unit.

[0063] Based on this, the embodiments of this application improve the situation where local blockage of the heat storage body affects gas flow and heat exchange by changing the arrangement of the heat storage body, thereby improving the operational stability of the regenerative combustion device. The waste gas treated by the regenerative combustion device can be waste gas generated during battery manufacturing or waste gas produced in other industrial processes; no specific limitations are imposed here.

[0064] According to some embodiments of this application, please refer to Figures 1 to 3 , Figure 1This is a front view schematic diagram of the regenerative combustion device 100 in some embodiments of this application. Figure 2 This is a front view schematic diagram of a portion of the regenerative combustion device 100 in some embodiments of this application. Figure 3 This is a side view of another part of the regenerative combustion device 100 in some embodiments of this application. This application provides a regenerative combustion device 100, including a body 110 and a plurality of heat storage bodies 120. The body 110 has a receiving cavity Q, which includes a combustion region z1 and a plurality of heat storage regions z2, all of which are connected to the combustion region z1. The combustion region z1 is located on the top side of the plurality of heat storage regions z2, and the heat storage regions z2 are provided with a plurality of heat storage bodies 120. Within the same heat storage region z2, all heat storage bodies 120 are spaced apart along the direction from the top side of the body 110 to the bottom side of the body 110, and a spacer channel P is defined between two adjacent heat storage bodies 120. The heat storage region z2 has a target region mz located between the top side of the body 110 and a reference surface E. Within the same heat storage region z2, at least one spacer channel P is located within the target region mz of the heat storage region z2. The reference plane E is perpendicular to the top side of the body 110 and points to the bottom side of the body 110. The heat storage region z2 has a central axis L that is perpendicular to the top side of the body 110 and points to the bottom side of the body 110. The central axis L is located on the reference plane E.

[0065] The body 110 is a component used to provide mounting and support for the various parts in the regenerative combustion device 100. The body 110 may have certain dimensions along a first direction F1, a second direction F2, and a third direction F3. The first direction F1 and the second direction F2 may be horizontal, and the third direction F3 may be vertical. For example, the first direction F1, the second direction F2, and the third direction F3 are mutually perpendicular. The body 110 has a top side and a bottom side disposed opposite each other along the third direction F3. The direction from the top side of the body 110 to the bottom side of the body 110 is parallel to each other in the third direction F3.

[0066] Combustion zone z1 is the area for burning exhaust gas. For example, the regenerative combustion device 100 also includes a burner, which can use fuels such as oil or natural gas for combustion. Regenerative zone z2 is the area for arranging a heat storage body 120, which stores heat. Multiple heat storage zones z2 are provided; adjacent heat storage zones z2 can be spaced apart or partially spaced, without specific limitations. The regenerative combustion device 100 can have two, three, five, or seven heat storage zones z2, etc., without specific limitations. In the embodiments of this application, using... Figure 1 and Figure 2 For example, the case with three heat storage zones z2 is illustrated.

[0067] exist Figure 2In the illustrated scenario, to facilitate the explanation of the division of the regions within the receiving cavity Q, dashed lines are used to indicate the division of the combustion region z1 and multiple heat storage regions z2. It should be noted that the dashed lines within the receiving cavity Q are only for illustrating the combustion region z1 and the heat storage regions z2. Within the receiving cavity Q, there may be no clear structural boundary to distinguish the combustion region z1 and the heat storage regions z2, or there may be a clear structural boundary to define the combustion region z1 and the heat storage regions z2; no specific limitation is imposed here. In the embodiments of this application, using... Figure 2 For example, it illustrates the situation where there is no obvious structural boundary between the combustion zone z1 and the heat storage zone z2, while there is an obvious structural boundary between two adjacent heat storage zones z2.

[0068] It is understood that the boundary between the combustion zone z1 and the heat storage zone z2 can be defined by the heat storage body 120 disposed within the heat storage zone z2. There can be two, three, four, five, or other numbers of heat storage bodies 120 within the same heat storage body 120; no specific limitation is made here. For example, when three heat storage bodies 120 are disposed within the heat storage zone z2, the uppermost heat storage body 120 and the top wall of the receiving cavity Q define the combustion zone z1. As another example, when five heat storage bodies 120 are disposed within the heat storage zone z2, the uppermost heat storage body 120 and the top wall of the receiving cavity Q define the combustion zone z1.

[0069] The heat storage element 120 is a component with a porous structure. The heat storage element 120 can be made of ceramic, or other materials; no specific limitations are specified here. (Refer to the reference.) Figure 4 , Figure 4 This is a top view of the heat storage body 120 in some embodiments of this application. The heat storage body 120 has a plurality of vent holes 1201. The vent holes 1201 penetrate the heat storage body 120 in a direction from the top side of the body 110 to the bottom side of the body 110. That is, the vent holes 1201 penetrate the heat storage body 120 in a third direction F3.

[0070] Since all the heat storage bodies 120 within the same heat storage zone z2 are arranged at intervals along the third direction F3, defining interval channels P, the vent holes 1201 of the heat storage bodies 120 are connected to the adjacent interval channels P. The vent hole 1201 of the uppermost heat storage body 120 connects to the combustion zone z1 and the adjacent interval channel P, the vent hole 1201 of the middle heat storage body 120 connects to the two adjacent interval channels P, and the vent hole 1201 of the lowermost heat storage body 120 connects to the adjacent interval channel P and the interior of the corresponding pipe. In this way, a channel is formed for gas to flow between the combustion zone z1, the heat storage bodies 120, and the corresponding pipes. Among them, the middle heat storage bodies 120 are all heat storage bodies 120 within the same heat storage zone z2 except for the uppermost and lowermost heat storage bodies 120. It is understandable that when there are two heat storage bodies 120 in the same heat storage area z2, there is no heat storage body 120 located in the middle.

[0071] It is understandable that when all heat storage bodies 120 within the same heat storage area z2 are arranged sequentially adjacent to each other, the vent holes 1201 of two adjacent heat storage bodies 120 are arranged one-to-one, thus forming a gas flow channel. However, when a heat storage body 120 is partially blocked, it will directly lead to the blockage of the gas channel corresponding to the blocked part on the third direction F3, thereby affecting the gas flow rate. Compared with all heat storage bodies 120 within the same heat storage area z2 being arranged sequentially adjacent to each other, the embodiment of this application, by setting an interval channel P, helps to reduce the risk that the channel in the direction from the top side of the body 110 to the bottom side of the body 110 will be blocked due to partial blockage, thereby making the replacement cycle of the corresponding heat storage body 120 longer, and thus facilitating the maintenance of the heat storage combustion device 100.

[0072] In conjunction with the foregoing, since the definition of the heat storage region z2 is related to the heat storage body 120, the heat storage region z2 can be considered as being defined by the top side of the uppermost heat storage body 120 and the bottom side of the lowermost heat storage body 120. The central axis L of the heat storage region z2 can be considered as the axis located at the midpoint between the top side of the uppermost heat storage body 120 and the bottom side of the lowermost heat storage body 120 on the third direction F3. Since the target region mz of the heat storage region z2 is defined by the reference plane E and the top side of the body 110, and the central axis L of the heat storage region z2 is located on the reference plane E, the spaced channel P located within the target region mz can be considered as being approximately located in the upper part of the heat storage region z2. It should be noted that, in Figure 2 From the perspective shown, the reference plane E can be roughly regarded as a line, and the central axis L of the heat storage region z2 coincides with the reference plane E. The area of ​​the heat storage region z2 excluding the target region mz is the remaining region sz, which is defined by the reference plane E and the bottom side of the body 110.

[0073] When the exhaust gas contains silicon-containing organic compounds such as silicone oil, silane, and siloxane, they are more prone to oxidation at high temperatures, generating silicon dioxide. Silicon dioxide is more likely to crystallize on the surface of the heat storage body 120 near the combustion zone z1, gradually accumulating and causing blockage of the heat storage body 120. Since the spacer channel P located in the target zone mz can be considered to be roughly located above the heat storage zone z2, the airflow obstruction caused by blockage of the heat storage body 120 located closer to the top can be effectively mitigated.

[0074] Therefore, by arranging all the heat storage bodies 120 in the same heat storage region z2 at intervals, a spacer channel P is formed. When a part of the heat storage body 120 becomes blocked, the gas can flow through other parts of the heat storage body 120 to the corresponding spacer channel P and be redistributed to adjacent heat storage bodies 120. This improves the airflow obstruction of adjacent heat storage bodies 120 caused by local blockage of the heat storage body 120, thereby effectively reducing the gas flow resistance fluctuation caused by blockage. Since the heat storage body 120 closer to the combustion region z1 is more prone to blockage, by setting at least one spacer channel P in at least one heat storage region z2 closer to the combustion region z1, the gas flow resistance fluctuation caused by blockage can be further improved. Therefore, the regenerative combustion device 100 provided in this application embodiment can not only improve the operational stability of the regenerative combustion device 100, but also help reduce the risk that the channels in the direction from the top side of the body 110 to the bottom side of the body 110 will be blocked due to local blockage, thereby making the replacement cycle of the corresponding heat storage body 120 longer, and thus making it easier to maintain the regenerative combustion device 100.

[0075] Based on some embodiments of this application, please continue to refer to Figure 2 and in conjunction with reference Figure 5 and Figure 6 , Figure 5 This is a front view schematic diagram of the heat storage body assembly in some embodiments of this application. Figure 6 This is a front view schematic diagram of the heat storage body assembly in some other embodiments of this application. At least one heat storage region z2 is provided with at least three heat storage bodies 120. Within the heat storage region z2 with at least three heat storage bodies 120, the height h of all heat storage bodies 120 increases along the direction from the top side to the bottom side of the body 110. The height h of the heat storage body 120 is the dimension of the heat storage body 120 along the direction from the top side to the bottom side of the body 110.

[0076] by Figure 5 and Figure 6 For example, the height h of the heat storage body 120 can be regarded as the dimension of the heat storage body 120 along the third direction F3. All heat storage bodies 120 within the same heat storage region z2 constitute a heat storage body group.

[0077] It should be noted that "increasing trend" can include phased increases, such as an initial increase followed by a period of no change, and then another increase; it can also include continuous increases, such as a consistent rate of increase or an initial rapid increase followed by a slower increase. Taking an increasing trend of initial increase, then no change, and then further increase as an example, the increasing trend is divided into three phases: the initial increase phase, the period of no change, and the subsequent increase phase. As long as the overall trend is increasing, no specific restrictions are imposed. Figure 5 For example, the height h of the heat storage body 120 increases sequentially along the direction from the top side of the body 110 to the bottom side of the body 110. Figure 6 For example, the height h of the heat storage body 120 increases in stages along the direction from the top side of the body 110 to the bottom side of the body 110.

[0078] As mentioned above, when the exhaust gas flows from the top side of the body 110 to the bottom side of the body 110, the solid particles and other impurities carried by the exhaust gas are more likely to be deposited on the heat storage body 120 closer to the top side of the body 110. By configuring the height h of all the heat storage bodies 120 in the heat storage region z2 with at least three heat storage bodies 120 to increase in a certain direction, the volume of the heat storage body 120 closer to the top side of the body 110 can be set to be smaller. Therefore, even if the heat storage body 120 closer to the top side of the body 110 is partially blocked, the exhaust gas can pass through the partially blocked heat storage body 120 more quickly from the top side of the body 110 to the bottom side of the body 110, and be redistributed to the adjacent heat storage body 120 through the corresponding interval channel P, thereby further effectively reducing the fluctuation of gas running resistance caused by blockage.

[0079] Based on some embodiments of this application, please continue to refer to Figure 5 Within the heat storage region z2, which is provided with at least three heat storage bodies 120, the height h of all the heat storage bodies 120 increases sequentially along the direction from the top side of the main body 110 to the bottom side of the main body 110.

[0080] That is, in the heat storage area z2 provided with at least three heat storage bodies 120, along the direction from the top side of the body 110 to the bottom side of the body 110, the height h of the previous heat storage body 120 is greater than the height h of the next heat storage body 120.

[0081] By configuring the height h of all the heat storage bodies 120 in the heat storage region z2 with at least three heat storage bodies 120 to increase sequentially, the height h of the heat storage bodies 120 is roughly increased, forming a stepped structure. This allows the exhaust gas to pass through the heat storage bodies 120, which are more prone to clogging, more quickly, thereby further reducing the impact of the heat storage bodies 120, which have a high risk of clogging, on the gas flow.

[0082] Based on some embodiments of this application, please continue to refer to Figure 2 and Figure 3 Along the direction from the top side of the main body 110 to the bottom side of the main body 110, all heat storage bodies 120 have the same height h. The height h of the heat storage body 120 is the dimension of the heat storage body 120 along the direction from the top side of the main body 110 to the bottom side of the main body 110.

[0083] This not only makes the overall structure simpler, easier to manufacture and maintain, but also makes the airflow distribution more uniform.

[0084] Based on some embodiments of this application, please continue to refer to Figure 3 At least one heat storage region z2 is provided with at least three heat storage bodies 120, and at least two spacer channels P are provided within the at least one heat storage region z2. Within the heat storage region z2 with at least two spacer channels P, all spacer channels P have the same size in the direction from the top side of the body 110 to the bottom side of the body 110. The size of the spacer channel P is the spacer dimension d.

[0085] In this way, the structure and spacing channels P formed by the heat storage body 120 in the corresponding heat storage region z2 can be more regular, which not only helps to improve the uniformity of airflow distribution and control the pressure drop of airflow, but also helps to improve the stability of heat exchange efficiency of heat storage body 120 and the uniformity of temperature field in heat storage region z2.

[0086] Of course, in some other embodiments, the dimensions of the spacer channels P located within the same heat storage region z2 can be the same or different. When the dimensions of the spacer channels P located within the same heat storage region z2 are different, the dimensions of the spacer channels P can increase or decrease, and no specific limitation is made here.

[0087] Based on some embodiments of this application, please continue to refer to Figure 1 and Figure 3 and in conjunction with reference Figure 7 , Figure 7 The diagram shows a side view of the pull-out member 130 in some embodiments of this application. The regenerative combustion device 100 also includes multiple pull-out members 130, which are arranged in a one-to-one correspondence with multiple heat storage bodies 120. The pull-out member 130 is used to carry the corresponding heat storage body 120 and is pulled out and engaged with the main body 110.

[0088] The pull-out component 130 is a part that can be pulled out relative to the main body 110. When the pull-out component 130 carries the corresponding heat storage element 120, it can generally form a drawer-type pull-out structure. (Refer to reference) Figure 8 and Figure 9 , Figure 8This is a side view of the regenerative combustion device 100 in one state in some embodiments of this application. Figure 9 This is a top view schematic diagram of the regenerative combustion device 100 in one state according to some embodiments of this application, illustrating the situation where the pull-out member 130 is pulled out relative to the regenerative combustion device 100. Figure 9 The heat storage body 120 is not shown in the diagram.

[0089] When excessive silica is adsorbed in the heat storage medium 120, its heat exchange capacity is affected, leading to increased resistance and reduced processing capacity in the regenerative combustion device 100. When the regenerative combustion device 100 cannot meet normal operating requirements, the heat storage medium 120 needs to be repaired and replaced. Since the regenerative combustion device 100 in this technology is enclosed, and the heat storage medium 120 is filled in the middle, operators need to enter the interior of the regenerative combustion device 100 through a manhole. Inside the device, the heat storage medium 120 is gradually moved and emptied to the outside, and then new heat storage medium 120 is gradually moved from the outside to fill the interior, thus completing the replacement. Furthermore, during the replacement of the heat storage medium 120, the regenerative combustion device 100 cannot operate normally, and the exhaust gas must be treated by backup equipment, increasing production costs and occupying significant production space. During the process of replacing the heat storage body 120, due to space constraints and the structure of the heat storage body 120, not only can multiple people work at the same time, but there are also safety risks due to poor ventilation and the potential generation of toxic gases.

[0090] Thus, by setting up the pull-out component 130, the replacement method of the heat storage element 120 is changed to a pull-out method. When it is necessary to replace the corresponding heat storage element 120, the heat storage element 120 can be pulled out into the main body 110 simply by using the pull-out component 130, allowing the operator to replace the heat storage element 120. This reduces the difficulty and safety risks of replacement and improves the comfort of the working environment. At the same time, since all heat storage elements 120 can be pulled out individually, only the heat storage element 120 that needs to be replaced can be operated individually, making the maintenance process more flexible and convenient.

[0091] Based on some embodiments of this application, please continue to refer to Figure 1 and in conjunction with reference Figure 10 , Figure 10 for Figure 1 The enlarged structural diagram at point A shows that the regenerative combustion device 100 also includes multiple fixing components 140, which are correspondingly arranged with multiple pull-out parts 130. The fixing components 140 are used to detachably fix the corresponding pull-out parts 130 and the main body 110.

[0092] For example, the fixing component 140 may be a locking component, a pin component, a snap fastener component, a resilient clamp component, or a threaded component, without specific limitations. All fixing components 140 may be of the same type or different types, without specific limitations. In the embodiments of this application, all fixing components 140 are of the same type.

[0093] Thus, by providing the fixing component 140, the pull-out component 130 and the body 110 can be fixedly connected when the pull-out component 130 is inserted into the body 110. When it is necessary to pull the pull-out component 130 out of the body 110, the fixing component 140 can be opened to separate the pull-out component 130 from the body 110, thereby facilitating the removal of the pull-out component 130. This facilitates more convenient and efficient maintenance and replacement of the pull-out component 130, as well as more flexible modular expansion and adjustment.

[0094] Based on some embodiments of this application, please continue to refer to Figure 4 , Figures 7 to 9 The pull-out component 130 includes a support portion 131 for supporting the heat storage body 120. The support portion 131 is provided with a plurality of through holes 1301, which penetrate the support portion 131 in a direction from the top side of the body 110 to the bottom side of the body 110. The heat storage body 120 has a plurality of vent holes 1201, and the minimum diameter of the through holes 1301 is larger than the maximum diameter of the vent holes 1201.

[0095] The diameters of all through holes 1301 in the support portion 131 may be the same, not exactly the same, or completely different; no specific limitation is imposed here. The support portion 131 can generally form a mesh-like structure. The diameters of the vent holes 1201 in the heat storage body 120 may be the same, not exactly the same, or completely different; no specific limitation is imposed here.

[0096] Thus, by providing the support portion 131, it is not only beneficial to support the heat storage body 120 more stably and conveniently, but also to connect the vent hole 1201 of the heat storage body 120 and the corresponding spacer channel P through the through hole 1301, thereby facilitating the flow of exhaust gas within the heat storage region z2. Furthermore, the through hole 1301 on the support portion 131 also facilitates the passage of dust and other impurities. After the pull-out component 130 is pulled out of the body 110 and separated from the body 110, it can be directly cleaned by washing with water or back-blowing with compressed air.

[0097] It should be noted that insulation materials such as thermal insulation cotton can be installed on the exterior of the pull-out component 130 and on the main body 110, which is beneficial to improving the heat storage capacity of the heat storage combustion device 100.

[0098] Based on some embodiments of this application, please continue to refer to Figure 11 , Figure 11 This is a top view schematic diagram of another part of the structure of the regenerative combustion device 100 in some embodiments of this application. The regenerative combustion device 100 also includes a plurality of sliding components 150, and the plurality of sliding components 150 and the plurality of pull-out members 130 are arranged in a one-to-one correspondence. The sliding component 150 is engaged between the corresponding pull-out member 130 and the body 110, so that the pull-out member 130 is slidably connected to the body 110.

[0099] For example, with Figure 11 For example, the sliding assembly 150 includes a pulley 151 and a slide rail 152. The pulley 151 is rotatably mounted on the body 110, and the slide rail 152 is located on both sides of the pull-out member 130 along the first direction F1. The pulley 151 and the slide rail 152 cooperate along the second direction F2. In this way, when the pull-out member 130 is pulled out or inserted relative to the body 110, the cooperation of the pulley 151 and the slide rail 152 allows the pull-out member 130 to be pulled out or inserted more smoothly.

[0100] Thus, by setting the sliding component 150, the pull-out component 130 can be pulled out or inserted relative to the body 110 by sliding, thereby improving the flexibility of operation, the convenience of maintenance and the reliability of structure.

[0101] Based on some embodiments of this application, please continue to refer to Figure 4 The heat storage body 120 has multiple vent holes 1201. Within the same heat storage area z2, along the direction from the top side of the body 110 to the bottom side of the body 110, the minimum aperture of the vent holes 1201 of all heat storage bodies 120 tends to increase.

[0102] The phrase "showing an increasing trend" can be understood by referring to the illustrations in some of the aforementioned embodiments, and will not be repeated here. All vents 1201 of the heat storage body 120 may have one aperture or multiple apertures, and no specific limitation is made here.

[0103] Thus, by making the vent hole 1201 of the heat storage body 120 closer to the top side of the main body 110 relatively smaller, the time for exhaust gas to pass through the heat storage body 120 closer to the top side of the main body 110 can be extended, allowing the heat storage body 120 closer to the top side of the main body 110 to accumulate more heat, thereby improving the heat storage effect. By making the vent hole 1201 of the heat storage body 120 closer to the bottom side of the main body 110 relatively larger, the gas resistance for exhaust gas to pass through the heat storage body 120 closer to the bottom side of the main body 110 can be reduced, thereby improving the stability of the total gas volume, and further improving the operational stability of the regenerative combustion device 100.

[0104] Based on some embodiments of this application, please continue to refer to Figure 4Within the same heat storage area z2, along the direction from the top side of the body 110 to the bottom side of the body 110, the minimum aperture of the vent holes 1201 of all heat storage bodies 120 increases sequentially.

[0105] "Increasing sequentially" means that, along the direction from the top side of the body 110 to the bottom side of the body 110, the minimum diameter of the vent 1201 of the previous heat storage body 120 is greater than the minimum diameter of the vent 1201 of the subsequent heat storage body 120.

[0106] Thus, in the direction from the top to the bottom of the main body 110, a gradient design of the vent holes 1201 can be achieved within the heat storage region z2. This improves the heat exchange effect between the exhaust gas and the heat storage body 120 in the area near the top of the main body 110, while reducing gas resistance in the area near the bottom of the main body 110. Consequently, the heat exchange effect is improved while gas resistance is reduced, thereby enhancing the overall treatment effect of the regenerative combustion device 100. Furthermore, since exhaust gas is more prone to coking in the heat storage body 120 near the top of the main body 110 and more prone to ash accumulation in the heat storage body 120 near the bottom of the main body 110, by making the vent hole diameters of the vent holes 1201 near the top and bottom of the main body 110 different, differentiated maintenance of the heat storage bodies 120 located in different areas can be achieved, thereby reducing maintenance costs.

[0107] Based on some embodiments of this application, please continue to refer to Figures 1 to 3 All heat storage bodies 120 located in the same heat storage area z2 constitute a heat storage body group. All heat storage body groups are arranged along the first direction F1. The first direction F1 is perpendicular to the direction from the top side of the body 110 to the bottom side of the body 110.

[0108] The number of heat storage elements 120 in all heat storage groups can be the same or different. Figure 1 and Figure 3 For example, this illustration shows a scenario where five pull-out components 130 and five heat storage bodies 120 are provided for the same heat storage area z2. The number of heat storage bodies 120 is the same in all heat storage body groups. It should be noted that the number of heat storage bodies 120 in a heat storage body group can be set according to actual usage requirements, and no specific limitation is made here. The dimensions of the heat storage bodies 120 along the first direction F1 can be the same or different, and no specific limitation is made here.

[0109] In this way, by controlling the arrangement of the thermal storage units, it is not only easier to install and maintain, but also easier to control different thermal storage units separately, thereby improving processing efficiency and flexibility.

[0110] According to some embodiments of this application, please refer to Figure 12 , Figure 12This is a front view schematic diagram of the regenerative combustion device 100 in another state in some embodiments of this application. Figure 12 The diagram briefly illustrates the main body 110 and the heat storage body 120. The main body 110 has multiple sets of air vents, each corresponding to one of the heat storage zones z2. Each set of air vents includes an air inlet k1, an air outlet k2, and a backflushing air outlet k3, all of which are connected to their respective heat storage zones z2. The air inlet k1 is used for air intake, the air outlet k2 for air exhaust, and the backflushing air outlet k3 for backflushing.

[0111] For example, an air inlet pipe 161 is provided at the air inlet k1, an exhaust pipe 162 is provided at the exhaust outlet k2, and a cleaning pipe 163 is provided at the cleaning outlet k3. Valves may be provided on the air inlet pipe 161, the exhaust pipe 162, and the cleaning pipe 163, or valves may be provided on the air inlet k1, the exhaust outlet k2, and the cleaning outlet k3 to allow for the opening and closing of the air inlet pipe 161, the exhaust pipe 162, and the cleaning pipe 163. The exhaust pipe 162 can be used to connect to a dust removal device (not shown in the figure). Fans (not shown in the figure) may be connected to the air inlet pipe 161 and the cleaning pipe 163 to transport gas. Figure 12 In the image, arrows indicate the direction of the corresponding gas or wind flow.

[0112] Taking a configuration with three heat storage zones z2 and three heat storage body groups as an example, exhaust gas can enter the corresponding heat storage zone z2 through the air inlet k1 and be discharged to the combustion zone z1 through the heat storage body 120. During this process, the exhaust gas exchanges heat with the heat storage body 120, and the exhaust gas is preheated and discharged to the combustion zone z1 after reaching a certain temperature. Backflushing air enters the corresponding heat storage zone z2 through the cleaning port k3 and is discharged to the combustion zone z1 through the heat storage body 120. The backflushing air blows the residual, untreated exhaust gas in the corresponding heat storage body 120 to the combustion zone z1. The exhaust gas after combustion has a high temperature, flows through the corresponding heat storage body 120 and undergoes heat exchange, and is discharged through the exhaust port k2. By controlling the opening and closing of the corresponding valves, the air inlet k1, exhaust port k2, and cleaning port k3 are alternately opened or closed, and the three heat storage zones z2 alternately perform air intake, backflushing, and exhaust, thereby completing the preheating, backflushing, and discharge of the exhaust gas.

[0113] For example, in three heat storage zones z2, the exhaust port k2 and the blow-through port k3 corresponding to one of the heat storage zones z2 may be closed, while the air inlet port k1 may be open; the air inlet port k1 and the blow-through port k3 corresponding to another heat storage zone z2 may be closed, while the exhaust port k2 may be open; and the air inlet port k1 and the exhaust port k2 corresponding to the remaining heat storage zone z2 may be closed, while the blow-through port k3 may be open. The exhaust gas, after being preheated by the heat storage body 120 in one of the heat storage zones z2, enters the combustion zone z1. The oxidized exhaust gas is discharged through the exhaust port k2 corresponding to the other heat storage zone z2, and the back-blowing air is discharged to the combustion zone z1 through the blow-through port k3 corresponding to the remaining heat storage zone z2. Subsequently, the air inlet port k1 and the exhaust port k2 corresponding to one of the heat storage zones z2 are closed, while the blow-through port k3 is opened. The exhaust port k2 and the blow-through port k3 corresponding to the other heat storage zone z2 are closed, while the air inlet port k1 is open. The remaining heat storage zone z2 has its purge port k3 and air inlet k1 closed, while its exhaust port k2 is open. Exhaust gas enters the combustion zone z1 through the preheating chamber 120 via the air inlet k1 corresponding to the other heat storage zone z2. The oxidized exhaust gas is discharged through the exhaust port k2 corresponding to the remaining heat storage zone z2. Simultaneously, backflushing air is directed through the purge port k3 corresponding to one of the heat storage zones z2 to deliver any remaining exhaust gas into the combustion zone z1. Then, the air inlet port k1 and purge port k3 corresponding to one of the heat storage zones z2 are closed, while the exhaust port k2 is opened. The air inlet port k1 and exhaust port k2 corresponding to the other heat storage zone z2 are closed, while the purge port k3 is opened. The exhaust port k2 and purge port k3 corresponding to the remaining heat storage zone z2 are closed, while the air inlet port k1 is opened. The organic waste gas enters the combustion zone z1 after being preheated by the heat storage body 120 through the air inlet k1 corresponding to the remaining heat storage zone z2. The waste gas after combustion and oxidation is discharged through the exhaust port k2 corresponding to one of the heat storage zones z2. At the same time, air is sent into the combustion zone z1 through the purge port k3 corresponding to the other heat storage zone z2. This process can be repeated.
