Description

Technical Field

[0001] This utility model belongs to the field of RTO equipment technology, and more specifically relates to an RTO thermal storage ceramic waste heat recovery device. Background Technology

[0002] The regenerative thermal oxidizer (RTO) has a heat storage chamber and a heat release chamber, both of which are equipped with ceramic heat storage bodies. When treating waste gas, the high-temperature waste gas heats up the ceramic in the heat storage chamber and stores heat. Then, the gas is introduced in the reverse direction, turning the heat storage chamber into a heat release chamber. At this time, the high-temperature ceramic stored heat is used to heat the low-temperature waste gas. This cycle is repeated, which can save the energy consumption of heating the waste gas in the early stage.

[0003] To improve heat storage and release efficiency, ceramic blocks are typically stacked in the chamber. As a result, the lifespans of the upper and lower ceramic blocks differ. To ensure heat storage and release efficiency, the ceramic blocks located at the bottom of the chamber need to be replaced in a timely manner. The process involves removing the upper ceramic blocks from the top down before replacing the bottom ones, which is quite cumbersome.

[0004] The utility model patent with publication number CN220061779U discloses a quick-change mechanism for the bottom ceramic of an RTO. It installs the ceramic blocks of each layer on the guide rail of the same layer and slides the ceramic mounting frame on the guide rail. When changing the ceramic block, only the ceramic mounting frame needs to be moved to replace the bottom ceramic block, without having to replace the ceramic block located on the upper layer, which is convenient to operate.

[0005] However, the cavity is equipped with multiple layers of ceramic blocks. The above structure only allows for the replacement of the bottom layer ceramic blocks. If the bottom layer is replaced with a new ceramic block, and the middle layer ceramic blocks need to be replaced when they reach the end of their service life, the top layer ceramic blocks still need to be removed first, which is inefficient. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an RTO (Regenerative Thermal Oxidizer) ceramic waste heat recovery device, which eliminates the need to remove other layers of ceramic when replacing any layer of ceramic, resulting in high efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an RTO (Regenerative Thermal Oxidizer) ceramic waste heat recovery device, comprising a housing with openings at both the top and bottom, a plurality of heat storage layers disposed inside the housing, fixed sliding plates disposed on both sides of the heat storage layers, a supporting sliding plate disposed between two of the fixed sliding plates, the two ends of the supporting sliding plate respectively slidingly contacting the fixed sliding plates, a plurality of heat storage ceramics disposed on the supporting sliding plate, a plurality of through holes disposed on the supporting sliding plate, an outlet disposed on one side of the housing, and a sealing door disposed on the outlet.

[0008] Furthermore, the sealing door is hinged to the box body and can rotate up and down, with a support block provided below the sealing door.

[0009] Furthermore, baffles are provided on the four edges of the supporting slide plate, and the plurality of heat storage ceramics are located in the area enclosed by the baffles.

[0010] Furthermore, the fixed sliding plate is provided with a sliding groove, and the supporting sliding plate is provided with a sliding rail corresponding to the sliding groove.

[0011] Furthermore, the bottom of the supporting slide plate is provided with several reinforcing ribs.

[0012] Compared with the prior art, the beneficial effects of this utility model are: when it is necessary to replace the heat storage ceramic in one of the layers, open the corresponding sealed door on the outside of the box, and then pull out the support slide on the fixed slide of the heat storage layer in sequence. After replacing the heat storage ceramic on the support slide, put it back into the box. Thus, when replacing any layer of heat storage ceramic, it is not necessary to remove the heat storage ceramic of other layers first, which is highly efficient. Attached Figure Description
