The exhaust gas is heated in the regenerative chamber and then enters the combustion chamber to be burned. A ceramic regenerative structure is placed in the regenerative chamber to heat the exhaust gas.

[0003] Most of the ceramic heat storage structures in the heat storage chamber are stacked. In order to allow the gas to circulate better, the channels of the multi-layer ceramic heat storage structure correspond to each other up and down. The single channels of the multi-layer ceramic heat storage structure are combined to form a longer channel, namely the combined channel. Since the ceramic heat storage structure is stacked and the channels of the multi-layer ceramic heat storage structure correspond to each other up and down, after the exhaust gas enters the combined channel, it flows along the combined channel and finally flows out from the combined channel.

[0004] When this structure is in use, there is a possibility that the channel openings at both ends of the combined channel may be blocked, while the blockage inside the combined channel is less. However, the blockage of the channel openings will cause the exhaust gas to be unable to enter the combined channel, resulting in the less blocked part of the combined channel being unable to be used for heat storage.

[0046] The invention provides a heat storage body structure, which is applied to a heat storage furnace.

[0047] In one embodiment of the present invention, the heat storage structure includes a base 100 and a ring body 200, wherein the base 100 is provided with a plurality of channels 110, wherein the plurality of channels 110 are used for gas to pass through, wherein the gas may be untreated waste gas, waste gas after combustion, or VOCs gas; the ring body 200 is arranged outside the base 100, and the ring body 200 and the outside of the base 100 are enclosed to form a confluence area 300, and one end of the plurality of channels is connected to the confluence area 300. If the confluence area 300 is arranged away from the gas flow direction, the gas first enters the end of the channel 110 away from the confluence area 300, at which time the gas circulates along the channel and then converges at the confluence area 300; if the confluence area 300 is arranged facing the gas flow direction, the gas first enters the confluence area 300, at which time the gas is diverted in the confluence area 300 and diverted into the plurality of channels 110. When the heat storage body structures are stacked, a plurality of combined channels 130 can be formed, at least one ring body 200 is provided between the two heat storage body structures, and the plurality of combined channels 130 are all connected to the confluence area, so that when the gas enters from a combined channel 130, flows along the combined channel 130, and then enters the confluence area 300, then, after being diverted through the confluence area 300, the gas can enter another combined channel 130; when the heat storage body structures are stacked, that is, when the substrates 100 are stacked, for example, Fig.13, the first substrate 100a, the second substrate 100b, and the third substrate 100c are stacked together in sequence, and the channels 110 in the first substrate 100a, the second substrate 100b, and the third substrate 100c are combined to form a combined channel 130, wherein the first substrate 100a is located at the top, and the second substrate 100b is located between the first substrate 100a and the third substrate 100c, and the combined channel 130 blocked at both ends is defined as a first combined channel 131, and the combined channel not blocked at both ends is defined as a second combined channel 132. At this time, when the gas enters the stacked substrate 100 from the first substrate 100a, the gas can first enter the first substrate 100a through the second combined channel 132. Since the channel mouth of the first combined channel 131 is blocked, the gas cannot enter from The first combination channel 131 enters the first substrate 100a. At this time, the gas flows along the second combination channel 132 in the first substrate 100a and enters the confluence area 300 between the first substrate 100a and the second substrate 100b. At this time, the gas is redistributed in the confluence area 300. Part of the gas can enter the channel 110 with less blockage in the first combination channel 131 and flow along the second substrate 100b, so that the channel 110 with less blockage in the first combination channel 131 can be used, avoiding the waste of the channel 110 with less blockage in the first combination channel 131, and making use of the less blocked part of the combination channel 130, so as to store heat for the gas, thereby solving the technical problems existing in the prior art. At the same time, under the action of the confluence area 300, while improving the utilization efficiency of the channel 110 in the first combination channel 131, the channel opening of the first combination channel 131 can also be cleaned to a certain extent before it is completely blocked. Fig.14Specifically, the gas flows along the first combined channel 131 in the second substrate 100b, and then enters the confluence area 300 between the second substrate 100b and the third substrate 100c for diversion. At this time, part of the gas can enter the channel 110 of the third substrate 100c located in the first combined channel 131. Since the two ends of the first combined channel 131 are not completely blocked, when the gas flowing in the first combined channel 131 needs to flow out from the third substrate 100c, the gas will be compressed by the channel opening of the first combined channel 131. At this time, the speed of the gas flowing out of the channel opening of the first combined channel 131 is greater than the speed of the gas flowing in the first combined channel 131. In the process of gas flowing out, the caliber of the channel opening that is not completely blocked can be enlarged, so as to achieve the purpose of cleaning the channel openings that are not completely blocked at both ends of the first combined channel 131 to a certain extent. On the contrary, the gas flows along the first combined channel 131 in the second substrate 100b, and then enters the confluence area 300 between the first substrate 100a and the second substrate 100b for diversion. At this time, part of the gas can enter the channel 110 of the first substrate 100a located in the first combined channel 131. Since the two ends of the first combined channel 131 are not completely blocked, when the gas flowing in the first combined channel 131 needs to flow out from the first substrate 100a, the gas will be compressed by the channel opening of the first combined channel 131. At this time, the speed of the gas flowing out of the channel opening of the first combined channel 131 is greater than the speed of the gas flowing in the first combined channel 131. In the process of gas flowing out, the caliber of the channel opening that is not completely blocked can be enlarged, so as to achieve the purpose of cleaning the channel openings that are not completely blocked at both ends of the first combined channel 131 to a certain extent; Figure 1 shown.

[0048] The technical solution of the present invention is to set a confluence area 300 on the substrate 100. When the heat storage body structures are stacked together, a plurality of combined channels 130 can be formed. At the same time, the confluence area 300 can be located between the two heat storage body structures. The plurality of combined channels 130 are all connected to the confluence area 300. In this way, when the gas enters from a combined channel 130 and flows along the combined channel 130, and then enters the confluence area 300, then the gas is diverted through the confluence area 300 and can enter another combined channel 130. When the channel opening of one of the combined channels 130 is blocked and the gas cannot enter the stacked heat storage body structure, the gas can enter the stacked heat storage body structure from the combined channel 130 whose channel opening is not blocked, and then be diverted through the confluence area 300. After diversion, the gas enters the combined channel 130 whose channel opening is blocked but whose internal blockage is less for heat storage, thereby allowing the internal part of the combined channel 130 with blocked channel opening to be utilized for heat storage, thereby solving the technical problems existing in the prior art.

[0049] In one embodiment, reference Figure 2 , the number of the ring bodies 200 is configured as two, and the two ring bodies 200 are symmetrical about the substrate 100, wherein when two ring bodies 200 are arranged outside the substrate 100, that is, two confluence areas 300 are arranged outside the substrate 100, and the two confluence areas 300 are symmetrically arranged about the substrate 100, one end of each of the multiple channels is connected to one of the confluence areas 300, and the other end is connected to the other confluence area 300, that is, the two ends of the channel are respectively connected to the two confluence areas 300; when the two heat storage body structures are stacked, two ring bodies 200 are arranged between the two heat storage body structures. Under this structure, the heat storage body structure is more convenient when it is stacked and installed. The user does not need to distinguish the installation direction of the heat storage body structure. It is only necessary to arrange the two ring bodies 200 relative to each other to ensure that there is a confluence area 300 between the two heat storage body structures after the heat storage body structure is stacked and installed.

[0050] In one embodiment, reference Fig. 9 , Fig.10 The surface of the substrate 100 located in the confluence area 300 is a curved surface 120, and the channel is set to penetrate the curved surface 120. In this embodiment, the surface located in the confluence area 300 is a curved surface 120. Such a setting can reduce the accumulation of impurities in the gas on the surface of the substrate 100. Under the action of the curved surface 120, the gas will drive some impurities on the curved surface 120 to flow during the flow process. Specifically, the gas flows along the channel 110 and blows toward the confluence area 300. When the gas blows toward the confluence area 300, part of the gas will blow toward the surface of the substrate 100. When the gas blows toward When the surface 100 of the substrate is curved, due to the inclination of the curved surface, the force of the gas moving in the horizontal direction will act more on the inclined curved surface. At this time, the force of the gas moving in the horizontal direction will drive the impurities on the curved surface to flow. At the same time, the impurities flow on the curved surface 120, which is smoother than the flow of impurities on the plane. The reason is that the force of the gas moving in the horizontal direction will act less on the plane parallel to it; therefore, under the action of the curved surface, the accumulation of impurities in the gas on the surface of the substrate 100 can be reduced, which can further reduce the time of blockage of the channel opening of the substrate 100.

[0051] In one embodiment, the arc surface 120 is convex or concave or concave-convex, wherein the arc surface 120 can be convex, see Figure 3 , Figure 4Under the effect of the convexity of the arc surface 120, when the gas flows in the substrate 100, the impurities acting on the arc surface 120 can diffuse around the convex arc surface. Because multiple channels are connected to the confluence area 300, that is, multiple channels are connected to the convex arc surface, when the impurities diffuse around the convex arc surface, they can enter more channels, avoiding the situation where impurities enter a small number of channels in a concentrated manner, resulting in blockage of the small number of channels and the channel openings, further reducing the situation where the channel openings in the substrate 100 are blocked, thereby improving the use effect of the present application; among them, for the convex arc surface, the concave arc surface 120 and the concave-convex arc surface in this embodiment, when the substrate 100 is produced, they can be integrally formed with the substrate 100.

[0052] In one embodiment, a partial area or the entire area of ​​one end of the ring body 200 away from the substrate 100 is configured to be serrated or sawtoothed, wherein the purpose of the serrated or sawtoothed structure is to relieve pressure. When the number of the first combination channels 131 increases and the number of the second combination channels 132 decreases, the gas is less efficient when discharged and accumulates in the confluence area 300. In order to avoid excessive pressure in the confluence area 300 and excessive concentration that causes damage to the heat storage body structure, the gas accumulated in the confluence area 300 can flow laterally to a certain extent through the serrated or sawtoothed structure, move out of the confluence area 300, and relieve pressure in the confluence area 300 to avoid cracks and damage to the ring body 200 due to excessive pressure in the confluence area 300.

[0053] The present invention also provides a heat storage furnace, referring to Figures 5 to 7 , the regenerative furnace comprises:

[0054] A furnace body 600 is provided with a combustion chamber 610 and a plurality of heat storage chambers 620, wherein the plurality of heat storage chambers 620 are all connected to the combustion chamber 610; wherein the heat storage furnace further comprises a combustion system, wherein the combustion system comprises a combustion controller, a flame detector, a high-voltage igniter and a corresponding valve combination, wherein a high-temperature sensor is further provided in the furnace body 600, and the high-temperature sensor can feedback the temperature information in the combustion chamber 610, and the combustion controller adjusts the heating capacity according to the temperature information in the combustion chamber 610, so that the temperature in the combustion chamber 610 is within a preset temperature range; and

[0055] A plurality of heat storage parts 400 are arranged one by one in a plurality of heat storage chambers 620, wherein a substrate 630 for installing the heat storage part 400 is provided in the heat storage chamber 620, and the heat storage part 400 is installed on the substrate 630. The heat storage part 400 includes a plurality of heat storage body structures, wherein a plurality of heat storage body structures are stacked, and the heat storage body structures are stacked on the substrate 630. The specific structure of the heat storage body structure refers to the above embodiment. Since the heat storage furnace adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, a plurality of the heat storage body structures are stacked.

[0056] The technical solution of the present invention adopts the above-mentioned heat storage body structure. When the exhaust gas enters the heat storage chamber 620 for heat storage, the exhaust gas can avoid the first combination channel 131 on the heat storage body structure in the heat storage part 400, and can enter the heat storage part 400 through the second combination channel 132. At this time, under the action of the confluence area 300, the exhaust gas can pass through the confluence area 300 and enter the second combination channel 132, so that the channel with less blockage in the combination channel 132 can be fully utilized, thereby storing heat for the gas, thereby solving the technical problems existing in the prior art.

[0057] In one embodiment, reference Figures 7 to 9 The heat storage furnace also includes an auxiliary purge component 500, which is used to blow out the medium in the channel of the heat storage structure, wherein the medium may be unburned exhaust gas or impurities remaining in the heat storage structure. In this embodiment, under the action of the auxiliary purge component 500, impurities can be further prevented from remaining in the channel 110 of the heat storage structure, thereby reducing the risk of the channel being blocked. In this embodiment, no specific limitation is imposed on the auxiliary purge component 500.

[0058] In one embodiment, the auxiliary purge assembly 500 may adopt the following mechanism, referring to Figures 7 to 10 The auxiliary purge assembly 500 includes a shunt pipe 510 and a plurality of purge pipes 520, the shunt pipe 510 is installed outside the furnace body 600, and the plurality of purge pipes 520 are arranged one by one corresponding to the plurality of heat storage parts 400, that is, each heat storage part 400 is provided with a group of purge pipes 520, and the number of each group of purge pipes 520 is multiple. Specifically, at least one purge pipe 520 is arranged between two stacked heat storage body structures, and the heat storage body structure is provided with an avoidance groove 210 for the installation of the purge pipe 520, wherein the avoidance groove 210 is provided on the ring body 200, with reference to Fig.11 , Fig.12When there is one ring body 200 between the two substrates 100, the avoidance groove 210 is configured as a U-shaped structure. When there are two ring bodies 200 between the two substrates 100, the avoidance groove 210 is configured as a semicircular structure. The two avoidance grooves 210 can be spliced ​​to form a circular structure. When the two avoidance grooves 210 are spliced ​​to form a circular structure, the purge pipe 520 is also configured as a circular structure. At the same time, when the avoidance groove is configured as a semicircular structure, under the action of the avoidance groove 210 and the purge pipe 520, the stacked substrates 100 have a positioning effect. The specific positioning operation is to firstly place the heat storage body structure The purge pipe 520 is placed in the avoidance groove 210 of one of the semicircular structures. At this time, half of the purge pipe 520 is located outside the heat storage structure. When another heat storage structure is stacked with the heat storage structure, the avoidance groove 210 of the semicircular structure in the other heat storage structure can be directly stuck outside the purge pipe 520, so as to achieve the positioning effect of the two heat storage structures when splicing. Under this effect, the channels 110 on the stacked substrates 100 can correspond better up and down, so that the gas can flow more smoothly from the channel 110 in one substrate 100 to the other substrate 1 00 in the channel 110, which can avoid the situation where the pressure in the heat storage chamber 620 increases due to poor gas flow; one end of the multiple groups of purge pipes 520 all penetrate the combustion chamber 610 and the furnace body 600, and are connected to the shunt pipe 510. Specifically, the purge pipe 520 is arranged between the two layers of heat storage parts 400, wherein the gas used for auxiliary purge enters the multiple purge pipes 520 through the shunt pipe 510, and each purge pipe 520 is installed with a control valve body 530, and the opening and closing of the purge pipes 520 in the multiple heat storage chambers 620 are controlled by the control valve body 530; the purge pipe 520 is configured as a hollow tube with an opening at one end, and a purge hole is arranged on the outside, wherein the purge hole is arranged away from the purge direction of the heat storage chamber 620, that is, the purge direction of the heat storage chamber 620 is the same as the air outlet direction of the purge hole. Since the purge tube 520 is arranged between two stacked heat storage body structures, the gas blown out through the purge hole in the purge tube 520 can act on the heat storage body structure more quickly. In this way, the gas blown out through the purge hole can act more strongly on the confluence area 300, which can effectively avoid impurities remaining in the confluence area 300, and further avoid impurities clogging the channel opening on the substrate 100.

[0059] In one embodiment, reference Figure 7 , Fig. 9The auxiliary purge assembly 500 also includes a plurality of driving members 550, and the plurality of driving members 550 are arranged one by one corresponding to the plurality of purge pipes 520, wherein a group of driving members 550 is arranged corresponding to a group of purge pipes 520, that is, a group of driving members 550, a heat storage chamber 620, a heat storage part 400, and a group of purge pipes 520 are arranged correspondingly, and the driving members 550 are used to drive the purge pipes 520 to rotate so as to adjust the purge direction of the purge holes. In this embodiment, when exhausting, since the direction of the purge holes in the purge pipes 520 is facing the gas flow direction during exhaust, in order to prevent impurities in the heat storage body structure from entering the purge pipes 520 through the purge holes during exhaust, the purge pipes 520 can be driven by the driving members 550 to flip the purge pipes 520 so that the purge holes in the purge pipes 520 face the gas flow direction during exhaust, thereby preventing impurities from entering the purge pipes 520 through the purge holes. The purge pipe 520 is rotatably matched with the diverter pipe 510, wherein the connection between the purge pipe 520 and the diverter pipe 510 is sealed, and the purge pipe 520 is connected to the diverter pipe 510 via connectors such as bearings, and the end of the purge pipe 520 facing away from the diverter pipe 510 is connected to the driving member 550, wherein the structure of the driving member 550 is of various types, which is not limited in the present embodiment.

[0060] In one embodiment, the driving member 550 is located outside the furnace body 600, and one end of the purge pipe 520 connected to the driving member 550 passes through the furnace body 600 and is connected to the driving member 550, wherein the purge pipe 520 and the furnace body 600 are rotationally matched, and the purge pipe 520 and the furnace body 600 are sealed. In this embodiment, the driving member 550 can be driven by a first motor, and each purge pipe 520 is connected to a first motor, and the purge pipe 520 is driven by the first motor to rotate; when the heat storage chamber 6 20 When exhaust is required, the first motor drives the purge pipe 520 to rotate so that the purge hole is facing the flow direction of the gas during the exhaust process. At this time, impurities in the heat storage body structure can be prevented from entering the purge pipe 520 through the purge hole. At the same time, in order to clean the impurities in the heat storage body structure during the exhaust process, gas can be introduced into the diversion pipe 510 to make the gas enter the purge pipe 520 in the corresponding heat storage chamber 620. At this time, the purge pipe 520 can also blow out a certain amount of gas during the exhaust process to clean the heat storage body structure.
