Block heat exchangers are compact, modular heat exchange devices classified based on materials, structural designs,
application scenarios, and manufacturing processes. the structured summary of classification as below: Classification by Material
1. Graphite Block Heat Exchanger - Structural Features: Made of impregnated or molded impervious graphite, offering high corrosion resistance and
thermal conductivity. Common types include cylindrical block-type (e.g., Cylindrical Block Graphite Heat Exchanger)
and shell-and-tube graphite heat exchangers. - Applications: Ideal for corrosive media like strong acids or alkalis, such as heat exchange in phosphoric acid production. 2. Ceramic Block Heat Exchanger - Structural Features: Fabricated from monolithic ceramic blocks with elongated cross-sectional channels. The overlapping
arc-shaped channel walls enhance fluid flow efficiency. - Applications: Suitable for high-temperature or high-wear environments in chemical and energy industries. Classification by Structural Design
1. Block-and-Hole Heat Exchanger - Composed of multiple perforated graphite blocks stacked together, allowing fluid exchange through interconnected channels (e.g., *Cylindrical Block Graphite Heat Exchanger*). 2. Shell-and-Tube Block Structure - Modular shell-and-tube designs, including fixed-tube and floating-head types. Examples include *Complex Shell-and-Tube Graphite Heat Exchanger*. 3. Monolithic Block Heat Exchanger - Single-piece structures formed by casting or injection molding, eliminating welds and enhancing pressure resistance (e.g., ceramic or metal monolithic blocks). Classification by Special Functions
1. High-Pressure Thread-Locked Ring Heat Exchanger - Design Features: Employs threaded locking rings for sealing, suitable for high-pressure hydrogen environments (e.g., hydrogenation reaction systems). Corrosion resistance is improved via optimized materials like hydrogen-resistant steel. 2. Corrosion-Resistant Block Heat Exchanger - Examples include *Double-Side Corrosion-Resistant Cylindrical Block Graphite Heater*, designed for strong acid media. Classification by Manufacturing Process
1. Modular Assembly Type - Multiple modules connected via bolts or adhesives, facilitating maintenance (common in graphite heat exchangers). 2. Integrated Monolithic Type - Molded in one piece for high structural integrity, such as cast ceramic or metal blocks. Application Scenarios
- Chemical Industry: Graphite and ceramic block exchangers handle corrosive media (e.g., sulfuric acid, phosphoric acid). - Energy & High-Pressure Systems: Thread-locked ring exchangers are used in petroleum hydrogenation and high-pressure steam systems. - High-Temperature Environments: Ceramic blocks excel in waste heat recovery from high-temperature exhaust gases.
