Description
Technical Field
[0001] The utility model relates to the technical field of heat storage incinerators, in particular to an anti-blocking structure of heat storage bricks in an RTO chamber. Background Art
[0002] The regenerative thermal incinerator is also called a regenerative thermal oxidizer, or “RTO” for short.
[0003] As a terminal treatment facility for high-concentration exhaust gas treatment, the core of the RTO heat storage incinerator is to store the heat generated by high-temperature incineration of organic waste gas through heat storage, which is used to preheat the newly incoming exhaust gas, thereby saving the fuel consumption required for heating and reducing operating costs. Since other salts such as ammonium salts will be produced during the combustion process, part of the burned exhaust gas will enter the subsequent treatment stage through saddle rings and heat storage bricks, and part of the burned high-temperature exhaust gas will flow back to the front end of the system to preheat the exhaust gas, and eventually the ammonium salt will still remain in the chamber body. After a long period of accumulation, the saddle rings and heat storage bricks in the chamber body will gradually be blocked, which will not only reduce the heat storage capacity, but also produce a greater pressure drop. Under the existing technology, its filtering structure relies solely on an integrated filter mesh structure for processing, which is inefficient and difficult to replace. Therefore, those skilled in the art provide an RTO chamber body heat storage brick anti-blocking structure to solve the problems raised in the above background technology. Utility Model Content
