The utility model compared with prior art has the following advantages:

1, the utility model is simple in structure, reasonable in design and use easy and simple to handle.

2, the utility model will have the cold water of certain pressure by after the nozzle ejection, form low-pressure area at low pressure exhaust steam entrance location place, the low pressure exhaust steam will enter suction chamber and cold water mix heat exchange under swabbing action like this, and then the low pressure exhaust steam becomes condensate water and flows out recycling with the working water that has been heated through hot water outlet.Therefore, the utlity model has energy-saving and environmental protection, characteristics that economic worth is high.

3, the utility model friction, noiselessness, without corrosion, stable.

4, the utility model is lightweight, and floor space is little, can be in very narrow space mounting operation.

5, the utility model is safe and reliable, can well satisfy Production requirement, reaches the waste heat recovery purpose, has created huge economic benefit and social benefit.

6, the utility model has effectively utilized the low pressure exhaust steam, is the comprehensive saving to coal, oil, electricity, and water balance, the thermal balance of enterprise is had important intensive optimization function, and macro adjustments and controls and the sustainable development of whole national economy had good booster action; Owing to reduced the consumption of the energy, also just indirectly reduced to the chance of airborne release flue dust and sulfide simultaneously, greatly reduced exhaust noise, played environmental-protection function, economic benefit and social synthesis's benefit are very considerable.

7, the utility model scope of application is wide, and the low pressure exhaust steam with a large amount of heat energy that can effectively be applicable to emit in the industry production processes such as electric power, chemical industry, metallurgy, iron and steel is reclaimed, and plays energy-conserving and environment-protective, energy-saving and cost-reducing effect.

Below by drawings and Examples, the utility model is described in further detail.
