Closed-loop Condensate Recovery System  

Closed-loop Condensate Recovery Units are based on the theory of dynamic two-phase flow of vapor and liquid, utilizing a unique pressure regulating device and cavitation elimination device. They are complemented by an aspiration pressure regulating device and a high-temperature resistant pump, which completely eliminate the conditions for cavitation and vapor lock in high-temperature condensate pumps. This achieves closed-loop recovery of condensate and secondary vapor, prevents secondary aeration of condensate, significantly reduces energy and water consumption, and offers remarkable environmental benefits.  

Key features include:

● State-of-the-art technology Custom-designed cavitation eliminators and optimized pipeline design are crucial for preventing cavitation in hot water pumps. Separation of steam and water, exhaust of non-saturated steam, and automatic adjustment of liquid level are the fundamental guarantees for the smooth recovery of high-temperature water. 

● Environmentally friendly and energy-saving This unit recovers high-temperature water and flash steam in an enclosed system, saving fuel.20％－25% reductionCO2、SO2Reduces emissions of harmful substances like dust, decreases thermal and noise pollution. Additionally, minimizes secondary pollution to groundwater and soil from the boiler water treatment system's effluent.

Engineered assembly  

Closed storage tank:Manufactured from stainless or carbon steel, specially treated for high-temperature, high-pressure, and corrosion resistance. 

● Cleaning Equipment: Removes slag, rust, and oil from condensate, regularly discharges waste, ensuring the purity of recycled water 

● Flash Vaporizer: Utilizes the physical properties of water to undergo secondary flash vaporization of condensate in the recovery unit, supplying low-pressure steam pipelines or for reuse. 

Pressure Regulating Device: Utilizing multi-stage water seals andUTubing, which maintains a sealed environment within the drum, airtight, ensuring the drum's pressure is lower than the condensate pressure, allowing condensate to continuously flow into the recovery storage tank.

● Steam Erosion Eliminator: Forms a certain pressure at the liquid surface for two-phase flow of steam and liquid, supplemented by unique steam erosion elimination design, ensuring no cavitation occurs in high-temperature pumps under sealed conditions. 

● Steam Absorption Pressure Regulator: Utilizes hydraulic drive to introduce secondary flash steam into the recovery system for heat recovery. 

● Liquid Level: Equipped with a magnetic float level gauge with remote transmission function, the condensate pump is turned on or off based on the level signal. Also capable of remotely transmitting to the central control system to start or stop system operation. 

● High Temperature Pump: Features a unique seal that overcomes the temperature limitations of conventional pumps. 

● Automatic Control System: Pump failure automatic transfer, constant liquid level variable frequency operation, low pressure automatic shutdown, automatic alarm for leakage, overpressure, underpressure, phase missing, overcurrent, and overtemperature.
