RTO System Addressing Gas Flow Direction & Operational Requirements
Thank you for clarifying the critical details of your TO-RTO system’s gas flow and operational challenges—this correction is essential to optimizing the ceramic media configuration. Based on your explanation (dust/inorganic particles entering from the top via the oxidation chamber, clean ambient air entering from the bottom) and the need to decouple Tramex thermal expansion, we have revised the design to prioritize top-layer anti-clogging, low ΔP maintenance, and Tramex movement absorption. Below is the optimized solution, retaining the 3.5% zirconia-corundum material (proven suitable for your temperature/corrosion conditions).
RTO System consist of the honeycomb ceramic, RTO Ceramic, or named heat accumulator , heat-retaing mass or something else https://www.chempackings.com/ceramic-foam-filter/sic-ceramic-foam-filter-for-metal-filtration.html
1. Core Design Adjustment: From “Bottom Pretreatment” to “Top Protection + Bottom Thermal Buffer”
The key shift is reorienting the system to target dust at its entry point (top) and address Tramex expansion at the base (bottom). The revised configuration (total bed height 1.8m, matching your tower dimensions) is structured as follows:https://www.rtoceramic.com/product/honeycomb-ceramic-heat-exchanger/
| Layer Position | Component Specification | Function Priority |
| Top Layer (Anti-Clogging Zone) | 1 layer × 150×150×300mm zirconia-corundum block, 25×25 cells (625 holes/block, ~6mm aperture) | 1. Coarse interception of dust/inorganic particles (from oxidation chamber);2. Prevent fine cells below from clogging; 3. Facilitate top-surface cleaning (vacuum/water-washing). |
| Middle Layer (Heat Recovery Core) | 3 layers × 150×150×300mm zirconia-corundum block, 43×43 cells (1849 holes/block, ~3.49mm aperture) | 1. High-efficiency heat recovery (matches your MLM-180 performance);2. Low ΔP design (optimized for 30,000 Nm³/h). |
| Bottom Layer (Tramex Thermal Buffer) | 2 layers × φ50mm 99% alumina ceramic balls (total height 300mm) | 1. Absorb Tramex’s cyclic thermal expansion/contraction (600℃ cold-hot cycles);2. Decouple mechanical stress between Tramex and ceramic blocks;3. Support upper layers with low resistance (clean air inlet). |
