[0003] The patent with authorization announcement number CN219775748U discloses an installation structure for RTO ceramic thermal storage body, including a thermal storage chamber, a plurality of first regular thermal storage bodies, a plurality of groups of second regular thermal storage bodies and a grid, wherein the grid is arranged on the side wall of the thermal storage chamber, a plurality of first regular thermal storage bodies are stacked above the grid, a plurality of groups of second regular thermal storage bodies are arranged below the grid, and each group of second regular thermal storage bodies is detachably connected to the grid through a connecting piece.

The second regular heat storage body needs to be cleaned or replaced, and manual entry is required to remove the second regular heat storage body, which makes the removal process of the second regular heat storage body more troublesome and inconvenient to clean the crystal blockage of the second regular heat storage body. Utility Model Content

[0005] In order to improve the problem that the removal process of the blocked second regular heat storage body is complicated, which leads to the inconvenience of cleaning the crystal blockage of the second regular heat storage body, the present application provides a cleaning structure for RTO ceramic heat storage body.

[0013] In a specific possible implementation, L=√3R.

[0014] By adopting the above technical solution and setting the distance between the two water spray circles, the spray range of a single nozzle is increased while eliminating dead angles, thereby reducing the number of nozzles used and being more economical.

[0016] By adopting the above technical solution, a semicircular nozzle is used on the edge water guide pipe, so that the water sprayed by the semicircular nozzle can be used to clean the crystal blockage at the bottom of the second regular heat storage body, thereby improving the utilization rate of the cleaning water.

[0021] In a specific feasible implementation scheme, a first pressure sensor and a second pressure sensor are provided in the heat storage chamber, the first pressure sensor is arranged above the second regular heat storage body, and the second pressure sensor is arranged below the second regular heat storage body, the first pressure sensor and the second pressure sensor are commonly connected to a processing controller, the processing controller is connected to the flow regulating valve, and the processing controller is used to collect the pressure difference between the first pressure sensor and the second pressure sensor, and control the opening of the flow regulating valve according to the pressure difference value.

[0022] By adopting the above technical solution, when the second regular heat storage body is blocked, the difference between the first pressure sensor and the second pressure sensor increases, and then the flow regulating valve is controlled by the processing controller to increase the opening, so that the nozzle sprays water to clean the blockage at the bottom of the second regular heat storage body.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The embodiment of the present application discloses a cleaning structure for an RTO ceramic thermal storage body.

[0031] Reference Figure 1 A cleaning structure for an RTO ceramic heat storage body comprises a heat storage chamber 1, in which a grille 2 is fixedly provided, the grille 2 divides the heat storage chamber 1 into two parts, a plurality of mutually stacked first regular heat storage bodies 3 are provided above the grille 2, and the plurality of first regular heat storage bodies 3 are stacked to form a five-layer heat storage layer structure, a plurality of groups of second regular heat storage bodies 4 are also provided below the grille 2, and the plurality of groups of second regular heat storage bodies 4 are stacked to form a two-layer heat storage layer structure, two second regular heat storage bodies 4 in each group are arranged opposite to each other up and down, and the two second regular heat storage bodies 4 opposite to each other up and down are tied by binding strips and hung on the grille 2, the second regular heat storage bodies 4 are attached to the side wall of the heat storage chamber 1, a spray unit 5 is provided at the bottom of the heat storage chamber 1, the spray unit 5 is externally connected to a water supply device 6, the water supply device 6 can adopt water supply equipment such as a water pump and a water tower, the spray unit 5 is arranged below the second regular heat storage body 4, and the spray unit 5 can spray water toward the bottom of the second regular heat storage body 4.

[0032] Since the bottom temperature of the second regular heat storage body 4 in the heat storage chamber 1 is low, the agglomerated gas in the exhaust gas crystallizes at the bottom of the second regular heat storage body 4. When the exhaust gas crystallizes at the bottom of the second regular heat storage body 4 and blocks the heat storage body, water is sprayed on the bottom of the second regular heat storage body 4 through the spray unit 5. The water dissolves the crystal blockage and allows the second regular heat storage body 4 to pass through, thereby eliminating the need to take out the second regular heat storage body 4 for cleaning, thereby improving the convenience of cleaning the second regular heat storage body 4.

[0033] Reference Figure 1 , Figure 2The spray unit 5 in this embodiment includes a water pipe 51 and a nozzle 52. The number of the water pipes 51 is several. In this embodiment, the number of the water pipes 51 is five. The five water pipes 51 are arranged in parallel and spaced along the length direction of the heat storage layer. The plurality of nozzles 52 are arranged on the five water pipes 51 and communicated with the water pipes 51. The nozzles 52 include full-circle nozzles 521 and semi-circle nozzles 522. Two of the five water pipes 51 located at the edge are attached to the opposite side walls of the heat storage chamber 1. The nozzles 52 on the two water pipes 51 attached to the side walls of the heat storage chamber 1 are semicircular nozzles 522, and the nozzles 52 on the other water pipes 51 are full-circular nozzles 521. One ends of the five water pipes 51 are interconnected through a distribution pipe 53, and the other ends are interconnected through a connecting pipe 54. The distribution pipe 53 is connected to the water supply device 6 and transports water to each water pipe 51. The five water pipes 51 are connected through the distribution pipe 53 and the connecting pipe 54, so as to improve the consistency of the working state of each nozzle 52.

[0034] Reference Figure 1 , Figure 2 The outlets of the full-circle nozzle 521 and the semi-circle nozzle 522 are both directed toward the second regular heat storage body 4. The full-circle nozzle 521 can spray water within the range of a water spray circle 551 with a radius of R on the second regular heat storage body 4, and the semi-circle nozzle 522 can spray water within the range of a water spray semi-circle 552 with a radius of R on the second regular heat storage body 4. The distance between the centers of two adjacent water spray circles 551 is L, L≤√3R. In this embodiment, L=√3R is preferably selected, so that the nozzle 52 can increase the spraying range of a single nozzle 52 while eliminating dead angles, thereby reducing the number of nozzles 52 used, which is more economical. The distance between the center of the water spray semicircle 552 and the center of the adjacent water spray circle 551 is M, M=√3R, the distance between the semicircular nozzles 522 or the full-circular nozzles 521 on the same water pipe 51 is 3R, and the central angle corresponding to the intersection range of the water spray circle 551 and the water spray circle 551 and the water spray semicircle 552 is 60°.

[0035] When the nozzle 52 sprays water, there is usually an area between the full-circle nozzle 521 and the semi-circle nozzle 522 that cannot be sprayed, which is called a dead angle. By setting the spraying ranges of two adjacent nozzles 52 to overlap each other, the second regular thermal storage body 4 at the dead angle can be sprayed, thereby improving the effect of cleaning the blockage of the second regular thermal storage body 4. The semi-circle nozzle 522 is used on the edge water guide pipe 51, so that the water sprayed by the semi-circle nozzle 522 can be used to clean the second regular thermal storage body 4, thereby improving the utilization rate of the cleaning water.

[0036] Reference Figure 1The heat storage chamber 1 is fixedly provided with a first pressure sensor 71 and a second pressure sensor 72. The first pressure sensor 71 is arranged above the first regular heat storage body 3, and the second pressure sensor 72 is arranged below the second regular heat storage body 4. The pressure difference on both sides of the entire heat storage body layer is monitored by the first pressure sensor 71 and the second pressure sensor 72, so that the blockage condition in the second regular heat storage body 4 can be accurately judged. The first pressure sensor 71 and the second pressure sensor 72 are commonly connected to a processing controller 73. The first pressure sensor 71 and the second pressure sensor 72 are electrically connected to the input end of the processing controller 73. A flow regulating valve 74 is provided on the distribution pipe 53. The flow regulating valve 74 can be used to adjust the flow of water in the distribution pipe 53. The output end of the processing controller 73 is electrically connected to the flow regulating valve 74. The processing controller 73 outputs a control signal to the flow regulating valve 74 to control the opening of the flow regulating valve 74. A pressure difference safety interval is set in the processing controller 73. When the pressure difference value between the first pressure sensor 71 and the second pressure sensor 72 exceeds the safety interval, the processing controller 73 controls the opening of the flow regulating valve 74 to increase, so that the water spraying amount of the nozzle 52 increases, and the second regular heat storage body 4 is cleaned.

[0037] When the second regular thermal storage body 4 is clogged, the difference between the first pressure sensor 71 and the second pressure sensor 72 increases, and then the processing controller 73 controls the flow regulating valve 74 to increase its opening, so that the nozzle 52 sprays water to clean the blockage at the bottom of the second regular thermal storage body 4, which can accurately monitor the blockage of the thermal storage body and timely clean the second regular thermal storage body 4. As the blockage of the second regular thermal storage body 4 is dissolved and cleared, the pressure difference between the first pressure sensor 71 and the second pressure sensor 72 decreases, and the processing controller 73 controls the flow regulating valve 74 to decrease or close its opening, thereby reducing water waste.

[0038] The implementation principle of the cleaning structure for an RTO ceramic heat storage body in an embodiment of the present application is as follows: when the exhaust gas crystallizes at the bottom of the second regular heat storage body 4 and blocks the second regular heat storage body 4, the pressure difference between the first pressure sensor 71 and the second pressure sensor 72 increases, and the processing controller 73 controls the opening of the flow regulating valve 74 to increase, so that the nozzle 52 sprays water to the bottom of the second regular heat storage body 4, and the water dissolves the crystallized blockage at the bottom, so that the second regular heat storage body 4 is connected, thereby eliminating the need to take out the second regular heat storage body 4 for cleaning, thereby improving the convenience of cleaning the crystallized blockage in the second regular heat storage body 4.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
