Pneumatic Condensate Water Recovery System For Closed Recovery Of Condensate In Steam Heating Systems

Product Description:

The condensate water recovery device can be steam-driven or electric-driven according to different user requirements. The recovered condensate water can be directly returned to the boiler or to a specified location designated by the user. The condensate water recovery device mainly consists of a dedicated condensate water recovery pump, motor, recovery tank, cavitation elimination device, liquid level sensor, magnetic flip liquid level gauge, pressure gauge, filter, pressure regulating valve, blowdown valve, control panel, and other components.

Steam condensate water enters the tank through a steam trap, where steam and water are separated. When the liquid level sensor detects a high liquid level in the tank, it sends a high-level signal to the control panel. The control panel then activates the condensate water recovery pump. The high-temperature condensate water and a small amount of secondary steam are transported through the pump's cavitation elimination device and filter into the water tank (or the specified location designated by the customer). This completes the entire process of steam condensate water recovery.

When the liquid level sensor detects a low liquid level in the tank, it sends a low-level signal to the control panel. The control panel then shuts off the condensate water recovery pump. The recovery device operates in fully automatic control mode, with dual pumps operating in a backup mode and automatically switching between them. Simply turning on the power enables the device to operate.

Product Applications:

(1) It is used in industrial enterprises in the papermaking, chemical, petroleum, printing and dyeing, textile, brewing, rubber, and other industries with steam heating systems for closed-loop condensate water recovery.
(2) It can also be used for steam condensate water recovery in hotels, hospitals, and other civil buildings. It conveniently and effectively converts the condensate water generated by the indirect heat exchange system into closed-loop recovery, making it a product that replaces conventional open condensate water tanks.

Product Advantages:

(1) Anti-cavitation: The product utilizes an innovative cavitation elimination device to prevent pump cavitation, allowing the condensate water recovery system to operate under high temperature and sealed conditions.
(2) Energy-saving and environmentally friendly: The product fully recovers and utilizes condensate water, increases the boiler feed water temperature, improves boiler efficiency, saves fuel by approximately 20%, saves water by approximately 20-80%, reduces investment and operating costs of water treatment equipment, reduces thermal pollution, noise pollution, and emissions of pollutants such as smoke, dust, SO2, NOx from secondary steam, and mitigates environmental pollution.
(3) High automation: The product adopts measures such as automatic control of pump operation, automatic switching between dual pumps, and automatic alarms to achieve automated closed-loop water return operation.
(4) Compact size: The product is compact and integrated, occupying less space, easy to transport, install, and use, reducing civil construction investment.
(5) Simple structure: It integrates flash tanks, rapid condensate water discharge devices, pressure balance devices, liquid level sensors, purifiers, cavitation elimination devices, and water storage tanks. The pressure of the balance device in the water storage tank is generally below 0.1MPa. The system can achieve a series of intelligent program controls such as automatic opening and closing, automatic alarms, automatic pressure regulation, and automatic switching of condensate water pumps. The equipment has good overall integrity and is easy to install and maintain.
(6) Flexible installation: It can be installed at the beginning of the return water pipeline or according to the layout of steam-using equipment, it can be installed underground.
