Hybrid / Direct Contact Heat Exchanger

·Direct Contact Heat Exchange: Hot and cold media mix directly without tube wall thermal resistance, reducing heat loss.
·Simple Structure: No internal components such as tube bundles, reducing the risk of clogging and fouling.
·Integrated Functionality: Simultaneously completes media mixing and heat exchange processes.
·Pressure-resistant Shell Design: Adapts to high-pressure, high-temperature conditions and media containing impurities.

·Structure Form: Horizontal cylindrical shell with media injected directly through inlets for mixing.
·Working Principle: Hot and cold media transfer heat through direct contact and mixing.
·Connection Method: Flanged connections compatible with standard industrial piping.
·Applicable Media: Steam, water, process gases, and liquid media that can be directly mixed.
·Shell Material: Carbon steel or stainless steel, selectable based on media characteristics.
·Condition Adaptation: Different pressure ratings and length specifications configurable according to process requirements.

·Industrial Heating: Direct steam heating and mixing processes for process water.
·Condensate Recovery: Steam condensation and condensate recovery systems.
·Waste Gas Treatment: Direct cooling and scrubbing processes for high-temperature waste gas.
·Chemical Processes: Heating, cooling, and heat recovery for directly mixable media.

·Uneven Media Mixing with Large Temperature Distribution Differences
Check media inlet flow rate and injection angle; adjust internal water or steam distribution devices; verify media flow ratio meets design specifications.
·Vibration or Noise During Equipment Operation
Check if media flow rate exceeds the design range; confirm shell supports are secure; troubleshoot water hammer or cavitation in the media.
·Leakage at Shell Connections
Check if flange gaskets are aged or damaged; confirm flange faces for corrosion or deformation; tighten bolts evenly to the specified torque.

·Confirm media flow direction and connection positions during installation to avoid reverse installation.
·Gradually increase pressure and temperature before operation to avoid impact from sudden changes in media flow rate.
·Regularly inspect the interior of the shell to remove impurities and sediments to prevent clogging or corrosion.
·Drain media inside the equipment during long-term shutdown to prevent freezing or corrosion of the shell in low-temperature environments.
