Background Art

[0002] Electric heating RTO purification is a method of exhaust gas treatment and air pollutant purification using electric heating technology. It is a variant of the RTO system that uses electric heating elements instead of traditional burners to provide high-temperature oxidation conditions. The ceramic thermal storage bodies used in the RTO purification process are usually key components. They are used for heat recovery and thermal energy utilization. The ceramic thermal storage bodies have high thermal capacity and thermal conductivity, and can absorb thermal energy from the exhaust gas and release heat to preheat the fresh exhaust gas during the cycle reversal process. Over time and usage, the ceramic thermal storage bodies may be worn, blocked or otherwise damaged, which will affect the performance and efficiency of the RTO system.

The solid-liquid combustion chamber and the solid-liquid heat storage chamber are separated by a partition, and the partition is opened. The exhaust gas combustion chamber and the exhaust gas heat storage chamber are separated by a baffle. The solid-liquid heat storage chamber is connected to the solid-liquid waste box through a solid-liquid waste pipe. The baffle is evenly provided with fine holes. The exhaust gas heat storage chamber is also filled with a honeycomb heat storage body connected to the exhaust gas box through an exhaust pipe. The solid-liquid combustion chamber is connected to the exhaust gas combustion chamber, and a through hole is provided in the middle. The through hole is provided with a filtering device. The left end of the lower oxygen pipe and the left end of the upper oxygen pipe are both connected to the oxygen pump, and the oxygen pump is also connected to the oxygen extraction pipe. A burner is also provided below the lower oxygen pipe in the solid-liquid combustion chamber, and an electric heating pipe is also provided below the upper oxygen pipe in the exhaust gas combustion chamber. An exhaust pipe is also provided on the top of the exhaust gas combustion chamber, and the exhaust pipe is also connected to the chimney. The utility model can fully and efficiently process three types of waste, which is very environmentally friendly and efficient.

[0004] At present, the ceramic heat storage body is replaced by manually removing bolts, which is cumbersome to operate, inconvenient to replace, and reduces the replacement efficiency. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the current method of replacing the ceramic heat storage body is to manually remove the bolts to replace the ceramic heat storage body, which is cumbersome to operate, inconvenient to replace, and reduces the replacement efficiency.

After replacement, the bracket is pushed into the clean room, and the compression spring is compressed by closing the sealing cover, so that the ceramic heat storage body is installed in the clean room for continued use. In addition, multiple air holes are opened on the bottom plate, which can enable the ceramic heat storage body to better absorb heat energy, effectively achieving the effect of quick and convenient replacement of the ceramic heat storage body to avoid accidental injury.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-2 and Figure 5-6 An electric heating RTO device for facilitating replacement of heat storage ceramics is shown, comprising a device body 1 with a heating box 2 installed inside, a purification chamber 3 is equidistantly excavated at the side end of the device body 1, a sealing cover 4 is rotatably connected to the side of the purification chamber 3, and a sealing strip is installed on the inner wall of the sealing cover 4, a bracket 5 is slidably connected in the purification chamber 3, a card groove 16 is symmetrically excavated on the bottom wall of the purification chamber 3, a roller 11 corresponding to the slide groove 22 is fixedly connected to the bottom end of the bracket 5, and the roller 11 is slidably connected to the slide groove 22, and the bottom of the bracket 5 is fixedly connected There is a bottom plate 7, on which a plurality of air holes 8 are equidistantly bored, a ceramic heat storage body 6 is detachably connected to a bracket 5, a baffle 9 is fixedly connected to one end of the air hole 8 away from the bracket 5, a compression spring 10 is fixedly connected to one end of the baffle 9 close to the purification chamber 3, and the compression spring 10 is fixedly connected to the inner wall of the purification chamber 3 at one end away from the baffle 9, a pipe opening 17 is symmetrically bored at the bottom end of the purification chamber 3, and a conveying pipe is connected to the pipe opening 17, a sealing cover 4 is greater in height than the purification chamber 3, and the sealing cover 4 blocks the card slot 16.

[0027] This solution can be achieved. When the ceramic heat storage body 6 in the device body 1 needs to be replaced, the sealing cover 4 can be opened. At this time, the ceramic heat storage body 6 on the air hole 8 is easily pushed to the outside of the purification chamber 3 through the roller 11 and the slot 16 by the elastic force of the compression spring 10. The whole process is automated to avoid burns by hand contact. After the ceramic heat storage body 6 is cooled, the ceramic heat storage body 6 can be taken out of the bracket 5 for replacement. After replacement, the bracket 5 is pushed into the purification chamber 3, and the compression spring 10 is compressed by closing the sealing cover 4, so that the ceramic heat storage body 6 is installed in the purification chamber 3 for continued use. In addition, a plurality of air holes 8 are provided on the bottom plate 7, so that the ceramic heat storage body 6 can better absorb heat energy, effectively achieving the effect of quickly and conveniently replacing the ceramic heat storage body 6 to avoid accidental injury.

[0028] The second implementation method:

[0029] Figure 3-7 It is shown that the top end of one side of the bracket 5 is rotatably connected to the baffle bar 12 through the damping shaft 13, and the side end of the bracket 5 is opened with a groove 16 corresponding to the baffle bar 12, and the baffle bar 12 is engaged with the groove 16, the side end of the bracket 5 located above the groove 16 is rotatably connected to the limit plate 14, and the bracket 5 located on the side of the limit plate 14 is fixedly connected with a block 15, and the limit plate 14 conflicts with the block 15, and a tension spring 21 is fixedly connected to a side wall of the limit plate 14 close to the block 15, and the tension spring 21 is fixedly connected to the block 15 at one end away from the limit plate 14, and the side end of the sealing cover 4 is fixedly connected with a connecting block 19, and the side end of the device body 1 is opened with a groove 18 corresponding to the connecting block 19, and the connecting block 19 and the groove 18 are threadedly fixed by bolts 20.

[0030] This solution can be achieved. When the ceramic heat storage body 6 is replaced, after the bracket 5 is located outside the purification chamber 3, the limit plate 14 is rotated counterclockwise to rotate the baffle 12 out of the slot 16 through the damping shaft 13, so that the ceramic heat storage body 6 on the bottom plate 7 can be removed for replacement. After replacement, the baffle 12 can be inserted into the slot 16 again. At this time, the limit plate 14 is released and automatically reset to a vertical state with the ground through the tension spring 21, and the baffle 12 is limited to avoid the ceramic heat storage body 6 from being displaced when the ceramic heat storage body 6 is moved. After the replacement is completed, the sealing cover 4 can be closed to seal the purification chamber 3. At this time, the connecting block 19 coincides with the groove 18 and is threadedly fixed by the bolt 20, effectively achieving the effect of limiting the position during the replacement of the ceramic heat storage body 6.

[0031] 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.
