[0002] RTO is a regenerative incinerator, which is a highly efficient organic waste gas treatment equipment. Its working principle is to heat the organic waste gas to above 760 degrees Celsius, oxidize and decompose the volatile organic compounds (VOCs) in the waste gas into carbon dioxide and water. The heat generated by the oxidation process is stored in a special heat storage body, which heats up the heat storage body to "store heat".

[0003] The specification of Chinese patent CN219120588U discloses an RTO waste gas incinerator, which realizes heat exchange without intersection between intake and exhaust, plays a role in preheating the waste gas by purified gas, and also avoids the problem of inadequate purification of the waste gas due to direct discharge.

[0004] The heat storage components inside the RTO are usually composed of multiple pieces of heat storage ceramics stacked on each other. During the actual installation process, the heat storage ceramics installed in the lower layer may be damaged due to manual pressure. After long-term use, the heat storage ceramics inside the RTO also need to be replaced. When replacing, the stacked heat storage ceramics also need to be taken out piece by piece, which makes the disassembly and assembly efficiency of the heat storage ceramics low, prolongs the working time, reduces the working efficiency, and is inconvenient for the staff to use.

[0007] In the above-mentioned RTO for convenient replacement of thermal storage ceramics, it is convenient to disassemble, assemble and replace the thermal storage ceramics. The thermal storage ceramics can be protected during use, which is convenient for use by staff.

[0008] As a further improvement of the present application, an inverted U-shaped support rod is fixedly connected to the top of the fixing rod, two fixing holes are opened at the upper end of the isolation block, the end of the support rod away from the fixing rod is located in the fixing hole, and the two fixing holes are located at both ends of the diagonal of the isolation block.

The left and right lower ends of the furnace body 1 are respectively fixedly connected with an outlet pipe 12 and an exhaust pipe 13, and the end of the outlet pipe 12 away from the furnace body 1 is fixedly connected with a fan 14. Technical personnel in this field can select a suitable model of fan 14 according to actual needs, for example: YX9-35. The fan 14 can facilitate the discharge of air inside the furnace body 1.

[0026] Figure 3 and Figure 4 As shown: a circular opening is provided at the upper end of the isolation block 2, a fixing rod 3 is provided at the center of the circular opening, a plurality of fan-shaped heat storage ceramic blocks 5 are provided between two adjacent fixing plates 4, a plurality of air holes are provided on the surface of the fixing plate 4, and the plurality of air holes facilitate the movement of gas, an inverted U-shaped support rod 15 is fixedly connected to the top of the fixing rod 3, and the support rod 15 can stably support the fixing rod 3, and two fixing holes 16 are provided at the upper end of the isolation block 2, and the end of the support rod 15 away from the fixing rod 3 is located in the fixing hole 16 The two fixing holes 16 are located at both ends of the diagonal of the isolation block 2. The two fixing holes 16 located on the diagonal do not hinder the insertion and removal of the limiting plate 7. The two limiting grooves 6 are both arc-shaped and symmetrically distributed with the diagonal of the isolation block 2. The limiting plate 7 is completely matched with the limiting groove 6. The limiting plate 7 is composed of two upper and lower arc-shaped plates. The diameter of the upper arc-shaped plate is larger than the diameter of the lower arc-shaped plate, and the lower end of the upper arc-shaped plate is in contact with the fixing plate 4 located at the upper end. The upper and lower arc-shaped plates with different diameters facilitate the fixation of the limiting plate 7.

[0027] Figure 5 As shown: a high-temperature resistant sealing plate 8 is inserted at the upper end of the furnace body 1, which can effectively prevent the gas inside the furnace body 1 from escaping. The outer circle thread of the high-temperature resistant sealing plate 8 is penetrated by multiple bolts.

The middle part of the upper end of the furnace cover 9 is fixedly connected with a gas pipe 10. The gas pipe 10 is a hose. The hose is highly flexible and easy to move. The middle part of the lower end of the furnace cover 9 is fixedly connected with a burner 11. The gas pipe 10 discharges the gas into the furnace body 1, and then burns it through the burner 11, thereby treating the exhaust gas.

[0028] In the actual installation process of the heat storage ceramic block 5, the heat storage ceramic block 5 can be directly placed between two adjacent fixing plates 4 so that multiple heat storage ceramic blocks 5 form a complete circle, and then the limiting plate 7 is inserted into the limiting groove 6 to limit the heat storage ceramic block 5, and the fixing rod 3 is inserted into the isolation block 2, and the support rod 15 is inserted into the fixing hole 16 to stably support the fixing rod 3.

[0029] The second implementation method:

[0030] Based on the first embodiment, this embodiment adds a fixing box 17, a filter block 18, a rubber sealing plate 19 and a pressing plate 20, and the rest of the parts are consistent with the first embodiment.

[0031] Figure 6 and Figure 7 It is shown that: the right end of the exhaust pipe 13 is connected to a fixing box 17 through a flange, and the right end of the fixing box 17 is connected to an intake pipe through a flange. A filter block 18 is arranged in the fixing box 17, and the filter block 18 can effectively filter fine particles in the exhaust gas and pre-treat the exhaust gas. A rubber sealing plate 19 is arranged at the upper end of the filter block 18, and the lateral area of ​​the rubber sealing plate 19 is larger than the lateral area of ​​the filter block 18. The rubber sealing plate 19 can effectively prevent the exhaust gas from escaping. A pressing plate 20 is fixedly connected to the upper end of the rubber sealing plate 19, and the pressing plate 20 and the fixing box 17 are fixedly connected by bolts.

[0032] During use, the exhaust gas in the intake pipe enters the fixed box 17. The exhaust gas may contain fine particles. If the particles in the exhaust gas adhere to the inside of the heat storage ceramic block 5, it will not only be inconvenient to clean, affecting the exhaust gas treatment efficiency, but also reduce the service life of the heat storage ceramic block 5. The fine particles in the exhaust gas are filtered through the filter block 18, thereby effectively preventing the particles in the exhaust gas from adhering to the inside of the heat storage ceramic block 5 during movement, thereby protecting the heat storage ceramic block 5.

[0033] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
