[0053] Specifically, the ceramic filler 400 is one of XJ type ceramic filler 400, Pall ring ceramic filler 400, saddle ring ceramic filler 400 or stepped ring ceramic filler 400, preferably XJ type ceramic filler 400, which has high mechanical strength and can withstand large pressure and impact force, can resist high pressure air from the lower part and high pressure spray from the upper part, and improve its service life. A plurality of ceramic fillers 400 are stacked on the filter tray 300 to form a complex gas-liquid channel 320, so that the gas-liquid two-phase is fully mixed and separated in the filler layer to realize high-efficiency mass transfer process. The XJ type ceramic filler 400 can be selected as a corrugated structure and a saddle structure at the same time. The saddle structure has a large specific surface area and good fluid distribution performance, which can promote the full contact and mass transfer of the gas-liquid two-phase. The corrugated structure can increase the path and contact area of the gas-liquid flow, and further improve the mass transfer efficiency. Ensure that the gas-liquid two-phase is fully mixed and separated, and improve the smoothness of the gas flow.

[0054] In actual use, the principle of the heat storage tower anti-blocking protection system of the embodiment of the present application is:

[0055] The waste gas pipe 130 inputs the workshop waste gas from the industrial equipment into the heat storage chamber 120 (in the A1 direction), and sequentially passes through the filter tray 300 and the ceramic heat storage body 200, and reacts in the thermal oxidation chamber 110 (in the A2 direction). The burned waste gas is fully burned and forms flue gas, and the flue gas formed by combustion is finally discharged from the first flue gas pipe 140 on the other side of the tower body 100 (in the A3 direction). Figure 1 Figure 1 Figure 1

[0056] Specifically, the waste gas needs to pass through the filter tray 300 before entering the ceramic heat storage body 200. Specifically, referring to Figure 2 The filter tray 300 with S-shaped gas-liquid channel 320 can increase the gas-liquid contact area and contact time, so that the gas and liquid are fully mixed and separated during the flow process. Further, the downcomer on both sides of the filter tray 300 can guide the liquid accumulated in the filter tray 300 to the bottom of the tower body 100, so that the liquid can flow down smoothly, and at the same time, the gas can be prevented from short-circuiting through the downcomer. In addition, the end of the S-shaped filter element 310 can act as an overflow weir to promote the liquid higher than the end face of the filter element 310 to flow down to the downcomer 340 on both sides automatically;

[0057] On the other hand, the gap between the multiple layers of ceramic heat storage bodies 200 can be used for gas flow in the horizontal plane, and referring to Figure 3 ​​​The honeycomb holes in the heat storage unit 210 can be used for the gas to flow in the vertical plane, and specifically, the structure formed by the multi-layer ceramic heat storage body 200 can provide a three-dimensional flow space for the flue gas to flow in series, which can effectively avoid the blockage.

[0058] In summary, by optimizing the structure of the heat storage body, the airflow is multi-directional, and the intake air is pre-separated by the ceramic filler 400 and the filter plate 300, which reduces the solid waste blown into the ceramic heat storage body 200, improves the anti-blocking capability of the heat storage body, ensures the stability and efficiency of heat exchange, and reduces the performance degradation caused by blockage.

[0059] It should be noted that, in order to further reduce the blockage of the ceramic heat storage body 200, with reference to Figure 1 , the anti-blocking protection system of the heat storage tower further includes a cleaning mechanism, and the cleaning mechanism includes a mixed air box 610, an air outlet pipe 620, a low-temperature fan 640, a cleaning fan 650, an exhaust adjustment valve 660, and a fresh air source 670. The mixed air box 610 is provided with a first air inlet 611, a second air inlet 612, a third air inlet 613, and an air outlet 614. The first air inlet 611 is connected with the second exhaust pipe 630, and the second air inlet 612 is connected with the first exhaust pipe 140. The air outlet pipe 620 extends into the tower body 100 from the bottom of the tower body 100, and the air outlet pipe 620 is located in the middle of the tower body 100, and the air outlet of the air outlet pipe 620 is located below the ceramic heat storage body 200. The air outlet of the air outlet pipe 620 is in the shape of a horn, and is provided with a plurality of rotatable grid plates 621. In the vertical cross section of the air outlet pipe 620, the grid plates 621 on both sides can be inclined towards both sides, so that the air outlet range of the air outlet pipe 620 covers the filter plate 300. The air outlet pipe 620 is connected to the air outlet 614. The low-temperature fan 640 is arranged between the second air inlet 612 and the first exhaust pipe 140. The cleaning fan 650 is arranged between the air outlet 614 and the air outlet pipe 620. The exhaust adjustment valve 660 is arranged between the first air inlet 611 and the second exhaust pipe 630 to control the exhaust amount of the second exhaust pipe 630. The fresh air source 670 is connected to the third air inlet 613, and an air inlet adjustment valve 671 is arranged between the fresh air source 670 and the third air inlet 613.

[0060] Specifically, the cleaning mechanism has two working states:

[0061] With reference to Figure 4 , in the working state 1, the entire anti-blocking protection system of the heat storage tower is in the state of burning exhaust gas. At this time, the grid plates 621 are driven to rotate, so that the grid plates 621 are inclined towards the side of the exhaust gas pipe 130 where the intake air is located, so that the hot air blown out of the air outlet pipe 620 is directed towards the bottom of the ceramic heat storage body 200 near the side where the intake air is located (such as Figure 4 the direction of the arrow), so as to avoid the accumulation of solid waste in the ceramic heat storage body 200.

[0062] With reference to Figure 5 , the working state 2, the whole heat storage tower anti-blocking system is in the shutdown state, at this time, the driving grid plate 621 rotates, so that the hot air blown through the grid plate 621 can cover the whole ceramic heat storage body 200 (in the arrow direction), and the residual solid waste in the ceramic heat storage body 200 is blown away and falls into the ceramic filler 400. Figure 5

[0063] In actual use, the flue gas generated in the combustion zone has high temperature and low temperature, wherein, with reference to Figure 1 , the high-temperature flue gas will float up, and the low-temperature flue gas will sink down, the high-temperature flue gas enters the mixed air box 610 through the second flue gas outlet pipe 630, and the low-temperature flue gas enters the mixed air box 610 through the first flue gas outlet pipe 140, and further, the new air is injected at the third air inlet 613 for supplementing the air volume, and the mixed air flow in the mixed air box 610 is blown out from the air outlet pipe 620 through the air outlet 614, which is used for blowing away the residual solid waste in the ceramic heat storage body 200.

[0064] Preferably, with reference to Figure 6 , the cleaning mechanism further comprises a temperature sensor 680 and a control unit 690, the temperature sensor 680 is arranged at the air outlet end of the air outlet pipe 620, and is used for testing the temperature of the air flow blown out by the air outlet pipe 620; the control unit 690 is electrically connected with the temperature sensor 680 and receives the temperature information from the temperature sensor 680, and the control unit 690 is electrically connected with the flue gas regulating valve 660 and the air inlet regulating valve 671 to control the opening and closing degree of the flue gas regulating valve 660 and the air inlet regulating valve 671.

[0065] Specifically, the temperature of the new air source 670 is the lowest, and the temperature of the high-temperature flue gas is the highest, the temperature of the air flow actually blown out by the air outlet pipe 620 is measured by the temperature sensor 680, and is compared with the preset temperature range in the control unit 690, if it is higher than the highest value, the new air inlet volume is increased through the air inlet regulating valve 671, and the high-temperature flue gas discharge volume is reduced through the flue gas regulating valve 660, so as to avoid damage of the cleaning fan 650 caused by too high temperature, if it is lower than the lowest value, the high-temperature flue gas discharge volume is increased through the flue gas regulating valve 660, and the new air inlet volume is reduced through the air inlet regulating valve 671, so as to ensure that the blowing temperature can maintain the heat balance in the tower body 100.

[0066] It should be mentioned that, with reference to Figure 4 and Figure 5 , in the cross section, the grid plate 621 is spindle-shaped, and the spindle-shaped grid plate 621 has the following advantages in the heat storage tower anti-blocking system of the embodiment:

[0067] ​Firstly, the spindle-shaped grille 621 can promote airflow. When air flows through the spindle-shaped grille 621, due to the blocking and guiding effect of the grille 621, the air will form a complex flow path around the grille 621, generating turbulence and eddies, creating negative pressure between two adjacent grilles 621, which will cause the air in the air outlet duct 620 to be accelerated and blown towards the ceramic heat storage body 200.

[0068] Secondly, the spindle-shaped grille 621 has good resistance to deformation and impact. Since the air outlet duct 620 blows out high-speed, high-temperature, and high-pressure airflow, the spindle-shaped three-dimensional structure, combined with high-temperature resistant materials, can improve the overall service life.

[0069] Third, there is a gap between two adjacent spindle-shaped grid plates 621. By adjusting the size of the gap, solid particles can be intercepted, which can prevent solid waste from falling into the air outlet duct 620 and avoid damage to the cleaning mechanism.

[0070] In some embodiments, refer to Figure 1 and Figure 7 The heat storage tower anti-clogging system also includes a spray mechanism 500, which is located between the ceramic packing 400 and the ceramic heat storage body 200. The spray mechanism 500 covers the entire filter tower plate 300 and is used to spray cleaning fluid. The cleaning liquid sprayed by the spray mechanism 500 deposits tiny solid waste particles in the exhaust gas, causing them to clump together and fall onto the filter tower plate 300, where they accumulate in the ceramic packing 400. This prevents the tiny solid waste particles from clumping and accumulating in the ceramic heat storage body 200, further reducing the possibility of blockage. Preferably, the spray mechanism 500 includes a spray mechanism 500 and spray heads 520. The spray pipe 510 is connected to a cleaning liquid source. Multiple spray heads 520 are provided, fixed to and connected to the spray pipe 510. The spray direction of the spray heads 520 is towards the filter tower plate 300. The ends of the spray heads 520 are trumpet-shaped, and the end faces of the spray heads 520 are spherical. Multiple spray holes 521 are provided on the end faces of the spray heads 520. The trumpet-shaped spray heads 520 can increase the spray area of ​​each spray head 520 (along the filter tower plate 300). Figure 7 (The cleaning liquid is sprayed in the direction of the arrow). The spray areas of two adjacent spray heads 520 intersect, so that the spray area of ​​the spray head 520 covers the entire filter tower plate 300. The liquid sprayed by the spray head 520 can also flow along the downcomer plate 340 of the filter tower plate 300 into the heat storage chamber 120.

[0071] Furthermore, referring to Figure 7, the internal space of the spray head 520 is in a venturi structure, after the cleaning liquid flows into the spray head 520 from the spray pipeline 510, the cleaning liquid passing through the venturi structure can be partially atomized, further expanding the coverage range of the cleaning liquid, promoting the agglomeration of the small solid waste, and at the same time, the atomized cleaning liquid can blow the waste gas towards the small solid waste to the filter tower plate 300 below. Specifically, the venturi structure has a converging section, a throat section and a diverging section along the liquid flow direction, wherein the cross-sectional area of the converging section gradually decreases. This design makes the flow rate of the fluid gradually increase when it enters the converging section, according to Bernoulli's law, the increase of the flow rate will cause the decrease of the fluid pressure; the flow rate of the fluid in the throat section reaches the maximum value, and the pressure decreases to the minimum value, the size of the cross-sectional area of the throat section can produce different flow rates and pressures, which can be designed according to the actual needs, the throat section can help to stabilize the flow state of the fluid and reduce energy loss; the cross-sectional area of the diverging section gradually increases, after the atomized fluid passes through the throat section, the flow rate gradually decreases, and the pressure starts to recover, gradually converting the kinetic energy of the high-speed fluid into pressure energy, so that the fluid can flow out of the venturi with lower speed but higher pressure, improving the atomization effect.

[0072] Preferably, in order to drain the remaining liquid from the filter tower plate 300, referring to Figure 1 , the bottom of the tower body 100 is provided with a drain pipe 150, the water inlet of the drain pipe 150 is located below the air outlet of the waste gas pipe 130 and the smoke inlet of the first smoke outlet pipe 140. Avoiding liquid flowing out of the air outlet and the first smoke outlet pipe 140, further, a liquid level sensor is also arranged above the drain pipe 150, and the drain pipe 150 has a drain valve, the liquid level sensor and the drain valve are electrically connected, for controlling the opening and closing of the drain valve, and the liquid level sensor is also arranged below the air outlet of the waste gas pipe 130 and the smoke inlet of the first smoke outlet pipe 140.
