Abstract

The invention discloses a jet compression type deep condensation dead steam heat pump circulation system, relates to the technical field of heat pump systems, aims to solve the problems that an existing heat pump circulation system is low in heat pump evaporation temperature, low in heat pump performance coefficient and efficiency, poor in system energy saving performance and large in energy consumption and operation cost. The system comprises a first compressor, a heat pump condenser, a first throttling expansion valve, a heat pump first evaporator, a second throttling expansion valve, a heat pump second evaporator, an ejector, a first heat-carrying medium pipeline, a second heat-carrying medium pipeline, a first refrigerant pipeline, a second refrigerant pipeline, a third refrigerant pipeline, a fourth refrigerant pipeline, a fifth refrigerant pipeline, a sixth refrigerant pipeline, a seventh refrigerant pipeline, an eighth refrigerant pipeline, a ninth refrigerant pipeline, a first dead steam pipeline, a second dead steam pipeline and a third dead steam pipeline. According to the system, performance coefficient of the heat pump is improved by 15-20% through cascade evaporation and cascade compression, the ejector is used for replacing a compressor, and energy consumption and operation cost are effectively saved.

Description

Technical field [0001] The present invention relates to the technical field of heat pump circulation system, and in particular, there is a heat pump circulating system for injection compression depth condensate. Background technique [0002] Due to the continuous rise in energy prices, domestic coal prices have also risen sharply, saving energy, and reducing business costs have become an urgent task of enterprises. A large number of industrial states in the enterprise, the power station boiler is equipped with a boiler-free displacement container equipped with an oxygenator and a softening system to produce a large number of low-pressure steam, flash vapor (elastic) outward. In addition, during the use of steam, a large amount of low-pressure steam is generated due to the process of the process, causing great energy loss and waste, and the recycling economic value is huge. If such a recycled value is reasonably recycled, the economy Value is significant. [0003] In evaporation p...
