[0052] Reference Figure 1 A heat storage tower anti-blocking protection system according to an embodiment of the present invention comprises a tower body 100, a ceramic heat storage body 200, a filter tray 300 and a ceramic filler 400. The top of the tower body 100 is a thermal oxidation chamber 110, and the bottom is a heat storage chamber 120. An exhaust pipe 130 is arranged on one side of the bottom of the tower body 100, and a first smoke outlet pipe 140 is arranged on the other side. The exhaust pipe 130 and the first smoke outlet pipe 140 are connected to the heat storage chamber 120, and the first smoke outlet pipe 140 is connected to a chimney; the ceramic heat storage body 200 is built into the tower body 100, the ceramic heat storage body 200 is located between the thermal oxidation chamber 110 and the heat storage chamber 120, the ceramic heat storage body 200 is connected by a plurality of heat storage units 210, the heat storage unit 210 is a porous honeycomb ceramic, the upper and lower surfaces of the ceramic heat storage body 200 are both provided with a plurality of strip-shaped protrusions 220, and an air guide groove 230 is provided between two adjacent protrusions 220. In the vertical section of the ceramic heat storage body 200, the protrusions 220 and the air guide grooves 230 are arranged. 30 are all arc-shaped; the filter tray 300 is built into the tower body 100, the filter tray 300 is located below the ceramic heat storage body 200, the filter tray 300 is composed of a plurality of filter units 310, and in the vertical section of the filter tray 300, the filter unit 310 is S-shaped, and two adjacent filter trays 300 are interlocked to form an S-shaped gas-liquid channel 320. A plurality of connecting columns 330 are connected between two adjacent filter units 310. A downcomer 340 is provided at one end of the plate 300 close to the inner wall of the tower body 100; a plurality of ceramic fillers 400 are provided, and the ceramic fillers 400 are stacked on the filter tower plate 300; wherein, the ceramic thermal storage body 200 is provided with multiple layers, and the multiple layers of ceramic thermal storage bodies 200 are arranged from top to bottom, and there is a gap between two adjacent layers of ceramic thermal storage bodies 200, and the edges of the two adjacent layers of ceramic thermal storage bodies 200 are fixedly connected, and from top to bottom, the aperture of the honeycomb holes of the porous honeycomb ceramic gradually increases.

[0053] Specifically, the ceramic filler 400 is one of XJ-type ceramic filler 400, ball ring ceramic filler 400, saddle ring ceramic filler 400 or step ring ceramic filler 400, preferably XJ-type ceramic filler 400, which has high mechanical strength, can withstand high pressure and impact, can resist high-pressure air intake from the bottom, and high-pressure spray from the top, and improve its service life. Many ceramic fillers 400 are stacked on the filter plate 300 to form a complex gas-liquid channel 320, so that the gas-liquid two phases are fully mixed and separated in the packing layer to achieve an efficient mass transfer process, and the XJ-type ceramic filler 400 can simultaneously select a corrugated structure and a saddle structure. The saddle structure has a large specific surface area and good fluid distribution performance, which can promote full contact and mass transfer between the gas and liquid phases; and the corrugated structure can increase the path and contact area of ​​the gas-liquid flow, further improving the mass transfer efficiency. While ensuring that the gas and liquid two phases are fully mixed and separated, the smoothness of the gas flow is improved.

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

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

[0056] The exhaust gas needs to first pass through the filter tray 300 before entering the ceramic heat storage body 200. Figure 2 The filter tray 300 with the 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. Furthermore, the downcomers 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, ensuring that the liquid can flow down smoothly while preventing the gas from short-circuiting through the downcomers. In addition, the end of the S-shaped filter unit 310 can be used as an overflow weir to cause the liquid above the end surface of the filter unit 310 to automatically flow down to the downcomers 340 on both sides.

[0057] On the other hand, the gaps between the multi-layer ceramic heat storage bodies 200 allow the gas to flow in the horizontal plane. Figure 3The honeycomb holes in the heat storage unit 210 allow the gas to flow in a vertical plane. Specifically, the structure composed of the multilayer ceramic heat storage body 200 can provide a three-dimensional flow space for the flue gas, and the flue gas can flow in the three-dimensional flow space and effectively avoid blockage.

[0058] In summary, by optimizing the structure of the heat storage body, the airflow is made to flow in multiple directions. At the same time, the intake air is pre-separated through the ceramic filler 400 and the filter tower plate 300, which reduces the solid waste blown into the ceramic heat storage body 200, improves the anti-clogging ability of the heat storage body, ensures the stability and efficiency of the heat exchange, and reduces the degradation of system performance caused by blockage.

[0059] It should be mentioned that in order to further reduce the clogging of the ceramic thermal storage body 200, refer to Figure 1 The heat storage tower anti-blocking protection system also includes a cleaning mechanism, which includes a mixing wind box 610, an air outlet pipe 620, a low-temperature fan 640, a cleaning fan 650, a smoke outlet regulating valve 660 and a fresh air source 670. The mixing wind 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 to the second smoke outlet pipe 630, and the second air inlet 612 is connected to the first smoke outlet pipe 140; the air outlet pipe 620 extends from the bottom of the tower body 100 to the inside of the tower body 100, the air outlet pipe 620 is located in the middle of the tower body 100, and the air outlet is located below the ceramic heat storage body 200. The air outlet of the air outlet pipe 620 is trumpet-shaped and is provided with a plurality of rotatable The grille plate 621 is on the vertical section of the air outlet pipe 620, wherein the grille plates 621 on both sides can be tilted toward both sides respectively so that the air outlet range of the air outlet pipe 620 covers the filter tower plate 300, and 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 smoke outlet pipe 140; the cleaning fan 650 is arranged between the air outlet 614 and the air outlet pipe 620; the smoke outlet regulating valve 660 is arranged between the first air inlet 611 and the second smoke outlet pipe 630 to control the smoke outlet amount of the second smoke outlet pipe 630; the fresh air source 670 is connected to the third air inlet 613, and an air inlet regulating 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] Reference Figure 4 In working state 1, the whole heat storage tower anti-blocking protection system is in the state of burning exhaust gas. At this time, the grid plate 621 is driven to rotate so that the grid plate 621 is tilted toward the air intake side of the exhaust pipe 130, so that the hot air blown out of the air outlet pipe 620 is directed toward the bottom of the ceramic heat storage body 200 close to the air intake side (such as Figure 4 The solid waste in the exhaust gas is prevented from accumulating in the ceramic heat storage body 200;

[0062] Reference Figure 5 , working state 2, the entire heat storage tower anti-blocking protection system is in a shutdown state, at this time, the grid plate 621 is driven to rotate so that the hot air blown out through the grid plate 621 can cover the entire ceramic heat storage body 200 (along Figure 5 ), the solid waste remaining in the ceramic thermal storage body 200 is blown away and falls into the ceramic filler 400.

[0063] In actual use, the flue gas generated in the combustion zone has high and low temperatures, among which Figure 1 The high-temperature flue gas will float up, while the low-temperature flue gas will sink. The high-temperature flue gas enters the mixing wind box 610 through the second smoke outlet pipe 630, while the low-temperature flue gas enters the mixing wind box 610 through part of the first smoke outlet pipe 140. Furthermore, fresh air is injected into the third air inlet 613 to supplement the air volume. The mixed air flow in the mixing wind box 610 is blown out from the air outlet pipe 620 through the air outlet 614 to disperse the solid waste continuing in the ceramic heat storage body 200.

[0064] Preferably, refer to Figure 6 The cleaning mechanism also includes 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 to test the temperature of the air flow blown out of the air outlet pipe 620; the control unit 690 is electrically connected to the temperature sensor 680 and receives temperature information from the temperature sensor 680. The control unit 690 is electrically connected to the smoke outlet regulating valve 660 and the air inlet regulating valve 671 to control the opening and closing degree of the smoke outlet regulating valve 660 and the air inlet regulating valve 671.

[0065] Specifically, the temperature of the fresh air source 670 is the lowest, while the temperature of the high-temperature flue gas is the highest. The temperature of the airflow actually blown out of the outlet pipe 620 is measured by the temperature sensor 680 and compared with the preset temperature range in the control unit 690. If it is higher than the maximum value, the fresh air intake is increased through the air intake regulating valve 671, and the high-temperature smoke exhaust is reduced through the smoke outlet regulating valve 660 to avoid excessive temperature from damaging the cleaning fan 650; if it is lower than the minimum value, the high-temperature smoke exhaust is increased through the smoke outlet regulating valve 660, and the fresh air intake is reduced through the air intake regulating valve 671 to ensure that the blowing temperature can maintain the thermal balance inside the tower body 100.

[0066] It is worth mentioning that, refer to Figure 4 and Figure 5 In cross section, the grid plate 621 is spindle-shaped. The spindle-shaped grid plate 621 has the following advantages in the heat storage tower anti-blocking protection system of this embodiment:

[0067] First, the spindle-shaped grid plate 621 can promote the flow of air. When the air flows through the spindle-shaped grid plate 621, due to the blocking and guiding effect of the grid plate 621, the air will form a complex flow path around the grid plate 621, generating turbulence and eddy current phenomena, and forming a negative pressure between two adjacent grid plates 621, which accelerates the air in the air outlet duct 620 to blow toward the ceramic thermal storage body 200;

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

[0069] Thirdly, there is a gap between two adjacent spindle-shaped grid plates 621. By adjusting the size of the gap, solid particles can be intercepted, that is, solid waste can be prevented from falling into the air outlet pipe 620, thereby preventing the cleaning mechanism from being damaged.

[0070] In some embodiments, reference Figure 1 and Figure 7 The heat storage tower anti-blocking protection system also includes a spray mechanism 500, which is arranged between the ceramic filler 400 and the ceramic heat storage body 200. The spray mechanism 500 covers the entire filter tower plate 300, and the spray mechanism 500 is used to spray the cleaning liquid. The cleaning liquid sprayed by the spray mechanism 500 is used to deposit the tiny solid waste in the exhaust gas, causing it to agglomerate and fall onto the filter plate 300 and accumulate in the ceramic filler 400, thereby preventing the tiny solid waste from agglomerating and accumulating in the ceramic heat storage body 200, and further reducing the possibility of clogging of the ceramic heat storage body 200. Preferably, the spray mechanism 500 includes a spray mechanism 500 and a spray head 520, and the spray pipeline 510 is connected to a cleaning liquid source; a plurality of spray heads 520 are provided, and the spray heads 520 are fixed on the spray pipeline 510 and connected to the spray pipeline 510, and the spray direction of the spray head 520 is toward the filter plate 300, and the end of the spray head 520 is trumpet-shaped, and the end face of the spray head 520 is spherical, and the end face of the spray head 520 is provided with a plurality of spray holes 521. The trumpet-shaped spray head 520 can expand the spraying area of ​​each spray head 520 (along the Figure 7 The cleaning liquid is sprayed in the direction of the arrow), and the spraying areas of two adjacent spray heads 520 intersect, so that the spraying area of ​​the spray head 520 covers the entire filter tower plate 300, wherein the liquid sprayed by the spray head 520 can also flow into the heat storage chamber 120 along the downcomer plate 340 of the filter tower plate 300.

[0071] Further, refer to Figure 7The internal space of the spray head 520 is a Venturi tube structure. After the cleaning liquid flows into the spray head 520 from the spray pipe 510, the cleaning liquid passing through the Venturi tube structure can be partially atomized, further diffusing the coverage of the cleaning liquid, thereby causing the tiny solid waste to agglomerate. At the same time, the atomized cleaning liquid can be used to blow the tiny solid waste in the exhaust gas onto the filter tower plate 300 below. Specifically, the Venturi tube structure has a contraction section, a throat and a diffusion section along the liquid flow direction, wherein the pipe cross-sectional area of ​​the contraction section gradually decreases. This design allows the fluid to gradually increase its velocity when entering the contraction section. According to Bernoulli's principle, an increase in velocity will lead to a decrease in fluid pressure. The velocity of the fluid in the throat reaches its maximum value, while the pressure drops to its minimum. Different throat cross-sectional areas can produce different flow rates and pressures, and can be designed according to actual needs. The throat can help stabilize the flow state of the fluid and reduce energy loss. The cross-sectional area of ​​the pipeline in the diffusion section gradually increases. After the atomized fluid passes through the throat, the velocity gradually decreases and the pressure begins to recover, gradually converting the kinetic energy of the high-speed fluid into pressure energy, allowing the fluid to flow out of the Venturi tube at a lower speed but higher pressure, thereby improving the atomization effect.

[0072] Preferably, in order to discharge the remaining liquid from the filter tray 300, refer to Figure 1 A drain pipe 150 is provided at the bottom of the tower body 100, and the water inlet of the drain pipe 150 is located below the gas outlet of the exhaust pipe 130 and the smoke inlet of the first smoke outlet pipe 140. To prevent liquid from flowing out of the gas outlet and the first smoke outlet pipe 140, a liquid level sensor is further provided above the drain pipe 150, and the drain pipe 150 has a drain valve, and the liquid level sensor is electrically connected to the drain valve to control the switch of the drain valve, and the liquid level sensor is also located below the gas outlet of the exhaust pipe 130 and the smoke inlet of the first smoke outlet pipe 140.

[0073] It is worth mentioning that, refer to Figure 4 A plurality of hanging rods 700 are arranged between the filter tray 300 and the ceramic thermal storage body 200. One end of the hanging rod 700 is fixed to the bottom of the ceramic thermal storage body 200 at the bottom layer, and a hook 710 is arranged at the other end. A plurality of hanging rings 720 are arranged on the surface of the filter tray 300. The hooks 710 and the hanging rings 720 are detachably buckled. It is convenient to upgrade and transform the existing thermal storage tower anti-blocking protection system, connect the filter tray 300 under the ceramic thermal storage body 200, and it is also convenient for the staff to replace the filter tray 300 and the ceramic filler 400 on the filter tray 300. Specifically, in order to facilitate maintenance, an inspection port is arranged on the outer wall of the tower body 100, and a switch door 160 is arranged on the inspection port.
