Description

Technical Field

[0001] This utility model belongs to the technical field of VOCs treatment equipment, specifically relating to the support structure of RTO heat storage bricks. Background Technology

[0002] In the field of industrial waste gas treatment, regenerative thermal oxidizers (RTOs) are highly efficient waste gas treatment equipment. The regenerative bricks, as the core component of the RTO, primarily function to store heat. When cold waste gas enters the RTO and passes through the hot regenerative bricks, the bricks act like a heat storage "warehouse," releasing previously stored heat to rapidly heat the waste gas to the required preheating temperature. Simultaneously, the regenerative bricks themselves cool down. The preheated gas smoothly enters the combustion chamber, where the high-temperature environment promotes the oxidation and decomposition of organic matter in the waste gas. The purified gas, after the reaction, exits the combustion chamber and passes through the cold regenerative bricks. The regenerative bricks absorb the heat from the purified gas, cooling it down, while the regenerative bricks themselves are reheated, completing a full heat storage-release cycle.

[0003] From the perspective of the entire RTO (Regenerative Thermal Oxidizer) equipment operation process, the regenerative bricks play a crucial and indispensable role, directly affecting the preheating effect of the waste gas, the decomposition efficiency of organic matter, and the cooling degree of the purified gas, thus determining the overall performance and operational stability of the RTO equipment. Therefore, if the support structure of the regenerative bricks is poorly designed, under the long-term stress caused by the weight of the bricks and temperature changes, the service life of the regenerative bricks is likely to be significantly reduced. More seriously, it may lead to a collapse of the regenerative bricks, which will not only prevent the RTO equipment from operating normally but also create safety hazards, cause production interruptions, and result in huge economic losses for the enterprise.

[0004] Currently, the most common support methods for thermal regenerator bricks are grid support and rectangular saddle ring packing. Grid support presents several challenges in manufacturing and installation. First, the numerous weld points necessitate extensive welding work, resulting in significant labor and time costs. Furthermore, the welding process itself, along with heat-affected zones, makes deformation highly likely. Deformation directly impacts the flatness of the thermal regenerator brick discharge surface. This change in flatness causes the bricks to tilt during placement, and over time, with continued equipment operation, the uneven stress on the tilted bricks can eventually lead to collapse. Additionally, the grid structure is relatively simple, mostly rectangular. This fixed structure limits its adaptability to different RTO equipment requirements and complex operating conditions, making it difficult to flexibly modify the internal structure.

[0005] Rectangular saddle ring packing has a relatively high manufacturing cost and is quite heavy, placing higher demands on the load-bearing capacity of the support structure and increasing the overall load on the equipment, leading to numerous inconveniences during installation and maintenance. Rectangular saddle ring packing is also brittle, easily breaking or breaking under external impacts, such as airflow impacts during equipment startup and shutdown, or collisions with foreign objects during operation. Once broken or damaged, the resistance to exhaust gas flow increases, affecting the normal flow of gas within the RTO equipment and thus reducing the RTO furnace's lifespan. Furthermore, adjacent rectangular saddle ring packings are prone to overlapping, reducing the effective surface area of ​​the packing and decreasing the contact area between the exhaust gas and the packing, directly affecting the exhaust gas flow rate and reducing the RTO equipment's processing efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a support structure for RTO thermal storage bricks, which solves the problem that existing thermal storage brick support structures are prone to deformation or breakage, resulting in unstable placement of the thermal storage bricks.

[0007] The technical solution adopted by this utility model is that the support structure of the RTO heat storage brick includes at least a connecting component that is fixedly connected to the inner walls of both sides of the heat storage chamber, a support component is overlapped on the top of any connecting component, the support component is fixedly connected to other connecting components, and the heat storage brick is placed on the support component.

[0008] The features of this utility model also include:

[0009] All connecting components include connectors, which are "L"-shaped angle steels. The sides of the connectors are fixed to the inner wall of the heat storage chamber. Each connector has a support component attached to its top, and the support component is fixedly connected to other connectors.

[0010] Several reinforcing ribs are fixedly installed at equal intervals on the connector, and each reinforcing rib is fixedly connected to the inner wall of the heat storage chamber.

[0011] The support structure includes a support frame, which overlaps with any connector. The bottom of the support frame is fixed to the top of other connectors. A blocking plate is fixed to the top of the support frame, and a uniform air distribution net is fixed to the top of the blocking plate. The top of the uniform air distribution net is in contact with the heat storage brick.

[0012] The outer edges of the support frame and the blocking plate are consistent with the shape of the interior of the heat storage chamber.

[0013] The support frame is composed of several flat steel bars, which are arranged in one of the following structures: square grid, diamond grid, or spider web grid.

[0014] The blocking plate has holes with the same shape as the outer edge of the bottom surface of the arranged heat storage bricks.

[0015] The uniform air distribution net is composed of several rhomboid or circular steel bars, and the contact between the uniform air distribution net and the bottom surface of the heat storage brick is a line contact.

[0016] The beneficial effects of this utility model are:

[0017] The support structure of the RTO heat storage brick provided by this utility model strengthens the support strength through connectors and several reinforcing ribs 5. The support strength can be adjusted according to the weight of the heat storage brick. In addition, the support frame is not fixed on one side. Under high temperature thermal expansion environment, the support frame can expand to the unfixed side when heated. At the same time, the air distribution net is in line contact with the bottom surface of the heat storage brick, which will not affect the gas throughput in the heat storage brick. This solves the problem that the existing heat storage brick support structure is prone to deformation or breakage, resulting in unstable placement of the heat storage brick. While ensuring strength and not affecting the waste gas throughput in the heat storage brick, it provides a more stable placement plane for the heat storage brick and avoids the heat storage brick's lifespan being reduced due to improper placement.
