Efficient Heat Transfer Bulk Solid Plate Heat Exchanger
Continuous Operation Gas Solid Two Phase Flow
Overview
Bulk solid heat exchanger is a highly efficient heat exchange equipment designed for bulk materials such as particles and powders. It adopts unique gas-solid two-phase flow technology and realizes efficient heat transfer through countercurrent heat exchange principle. The modular design facilitates equipment installation and maintenance while offering high temperature resistance and wear resistance characteristics.
Ideal for material preheating, cooling and other process applications in metallurgy, chemical, and building materials industries. Significantly reduces energy consumption while ensuring large processing capacity.
Key Features
- Thickened plate design (2.0mm+2.0mm double pillow plate): Withstands pressure of 4.0MPa (industry standard ≤2.5MPa), supports heat transfer oil (400℃) and high-pressure steam (6MPa)
- Anti-thermal deformation structure: Laser welding + corrugation compensation technology improves thermal stability under high temperature conditions by 40%
- Intelligent temperature control interlock: Cuts off heat source in 0.5 seconds when temperature exceeds limits, with failure rate <0.1 times/year
- Applicable scenarios: High-temperature catalyst, activated carbon particle cooling, and high-temperature solid processing in refineries
Technical Advantages
The bulk solid heat exchanger features a 2.0mm+2.0mm thickened double pillow plate structure (industry standard ≤1.5mm), providing 60% higher pressure resistance than conventional products. It can stably carry 4.0MPa high-pressure steam or 400℃ high-temperature heat transfer oil.
Laser welding corrugation compensation technology effectively disperses thermal stress under extreme temperatures, improving thermal stability by 40% and ensuring continuous operation in high-load scenarios such as refining and chemical industries.
Equipped with intelligent temperature and pressure interlocking system that cuts off heat source and initiates safe discharge within 0.5 seconds when pressure/temperature exceeds limits. Annual failure rate approaches zero, providing integrated heat exchange solution with extreme pressure resistance, thermal change resistance and zero downtime for high-risk media treatment.
