Description

Technical Field

[0001] This utility model relates to the field of heat storage body structure technology, and in particular to a three-tower RTO heat storage body structure. Background Technology

[0002] Currently, in the medical industry, the substances causing blockage in RTOs (Regenerative Thermal Oxidizers) mainly originate from specific components in medical waste gas. These components are prone to physical or chemical changes under high-temperature environments, forming solid deposits. Blockage often occurs in the ceramic packing bed of the regenerator, which is both the core of the RTO system and its most sensitive structural element. Among these, silicon (Si) compounds are the most common and primary cause of blockage in medical RTOs. These silicon compounds transform into glassy or ceramic solid deposits under high temperatures, adhering firmly to the surface of the ceramic regenerator and proving difficult to remove. The ceramic saddle ring is a crucial component in the highly efficient purification of medical waste gas in RTOs, playing a vital role in high-temperature flue gas due to its excellent adsorption performance and high-temperature resistance. Therefore, to effectively alleviate this problem, in addition to strengthening control at the source of waste gas and implementing efficient pretreatment, the structural design of RTO equipment should be optimized to improve its service life and treatment efficiency, thereby reducing the time and resource costs caused by frequent maintenance.

[0003] In novel RTO (Regenerative Thermal Oxidizer) systems, a dual-tower structure is employed to achieve regenerative combustion of waste gas, with a third tower used for waste gas recovery. This reduces the number of regenerator chambers while maintaining high waste gas treatment efficiency. However, in medical applications, despite implementing source emission control, efficient pretreatment processes, and reducing the number of regenerator chambers, the problem of regenerator blockage persists, requiring the system to rely on periodic manual cleaning and maintenance. Therefore, optimizing the regenerator structure itself has become a key direction for further improving the reliability and operational economy of RTO systems.

[0004] To address these issues, we developed an RTO heat storage structure. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology by providing an RTO heat storage structure that has the advantages of preventing blockage, extending lifespan, facilitating maintenance, and saving costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an RTO heat storage structure, including a support leg, a first chamber mounted on the top of the support leg, a first heat storage component mounted on the top of the first chamber, a second heat storage component mounted on the top of the first heat storage component, a second chamber between the first heat storage component and the second heat storage component, a combustion chamber mounted on the top of the second heat storage component, the second heat storage component including a saddle ring, a first maintenance door fixedly connected to the side wall of the first chamber, and a second maintenance door fixedly connected to the side wall of the second chamber.

[0007] Preferably, the second heat storage component includes a first support plate, a first grid strip at the top of the first support plate, a first grid mesh at the top of the first grid strip, and evenly distributed first compartments in the first grid strip, with the saddle ring inserted into the first compartment.

[0008] Preferably, the saddle ring has a semi-circular structure and its outer diameter is less than or equal to the height of the first compartment.

[0009] Preferably, the first heat storage component includes a first support column, a second support plate is provided at the top of the first support column, a second grid strip is provided at the top of the second support plate, the second grid strip is inserted into the saddle ring, and the second support plate and the support leg are fixedly connected by a first crossbeam.

[0010] Preferably, the second maintenance door is provided with first screw holes around its perimeter and a handle at the center position, and the first screw holes are fixedly connected to the outer wall of the second chamber by screws.

[0011] Preferably, a plug is provided at the middle position of the first maintenance door and is fixedly connected to the outer wall of the first chamber through a second screw hole.

[0012] Preferably, a cone is provided at the bottom end of the first chamber, and the cone is connected to a check valve.

[0013] Preferably, each of the two corners of the support leg in the first chamber is provided with a lifting lug.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: 1. Effectively prevents RTO clogging. The dual-grid structure and the addition of a saddle ring at the bottom of the regenerator ceramic significantly reduce the risk of clogging and facilitate cleaning, thereby improving overall processing efficiency.

[0015] 2. Extend RTO lifespan. By addressing clogging and corrosion issues, the equipment is effectively protected from exhaust gas corrosion, ensuring more stable and longer-lasting system operation.

[0016] 3. Convenient maintenance and cost-saving repairs. The optimized structure expands the maintenance space, and the maintenance door supports all-around cleaning, significantly reducing the time and manpower required for maintenance. Attached Figure Description

A second chamber 100 is located between the first regenerator component 205 and the second regenerator component 105. A combustion chamber is located at the top of the second regenerator component 105. The second regenerator component 105 includes a saddle ring 15. A first maintenance door 80 is fixedly connected to the side wall of the first chamber 200, and a second maintenance door 70 is fixedly connected to the side wall of the second chamber 100. A lifting lug 6 is provided at each of the two corners of the support leg 5 at the two corners of the first chamber 200. The lifting lugs are positioned diagonally to facilitate overall hoisting operations.

[0022] The second heat storage component 105 includes a first support plate 31. A first grid strip 21 is provided at the top of the first support plate 31, and a first grid mesh 11 is provided at the top of the first grid strip 21. The first grid strip 21 has evenly distributed first compartments 13, and saddle rings 15 are inserted into the first compartments 13. The first support plate 31 is fixedly connected by a second crossbeam 41, and a second support column 51 is fixedly connected to its bottom end. The second crossbeam 41 is an angle steel, and a square tube is fixedly connected to its side wall. The square tube is fixedly connected to the support leg 5. The second support column 51 raises the space of the second chamber 100, facilitating maintenance. The saddle ring 15 has a semi-circular structure, and its outer diameter is less than or equal to the height of the first compartment 13. The outer arc of the saddle ring 15 can be a minor arc. The first heat storage component 205 includes a first support column 52, and a second support plate 32 is provided at the top of the first support column 52. The first support column 52 facilitates the support and maintenance of the first chamber 200.

The second support plate 32 and the support leg 5 are fixedly connected by the first crossbeam 42.
