Based on Bernoulli’s principle (Venturi tube), the absorptiondriven power head is developed. By leveraging the inverse

relationship between fluid velocity and pressure, ambienttemperature water is mixed with low-pressure waste steam

through the absorption-driven power head to produce hightemperature water (70–90°C) for downstream users.

By adjusting the inlet diameter of the absorption power head, a

negative pressure environment is created at the inlet. Under this

negative pressure, direct drainage and waste steam are

transported over long distances and fully directed into the

recovery system for waste heat utilization.

The waste steam recovery system consists of an absorption

power head and a recovery unit body:

Absorption Power Head: Includes a waste steam suctioninjection device, film-forming chamber, follow-up absorption

unit, pressure-regulated rapid discharge device, and safety

valves.

Recovery Unit Body: Comprises a flow-guiding device, pressure

stabilizer, cavitation eliminator, decontamination unit, water

collection tank, butterfly valves, flow control pipes, hightemperature water delivery pumps, and a control system.

This technology is suitable for recovering low-pressure waste

steam (0.02–1.0 MPa) from industrial plants, including:

High-temperature, low-pressure waste steam from continuous

boiler blowdown.Deaerator exhaust steam.Turbine discharge

steam.Secondary flash steam.

Ambient-temperature water absorbs the waste steam to generate

high-temperature water (70–90°C) for production processes or

domestic use.

The unique suction-injection power

head of the recovery device utilizes the Venturi principle to

create a "negative pressure zone" at the inlet. This facilitates

seamless exhaust of waste steam without interfering with the

original production process.

A specially designed internal

structure effectively suppresses the water hammer phenomenon

caused by steam-water mixing, ensuring silent and vibrationfree operation.

Advanced multi-stage absorption

technology fully captures and recycles process-generated waste

steam, achieving zero emissions while eliminating thermal

pollution. This promotes energy conservation, emission

reduction, and sustainable production.

By applying dynamic two-phase flow

technology and the micro-subcooling principle, the system

eliminates cavitation risks in pumps during high-temperature

water delivery, ensuring reliable transport to designated

locations.

Equipped with intelligent

automation controls, the system operates fully autonomously

without manual intervention, requiring minimal maintenance.
