Description
Technical field
The present invention relates to heat pump techniques, more particularly to a kind of water resource heat pump.
Background technique
Building is carried out as heat source using the spent hot water of city discharge spent hot water, especially steel, chemical enterprise emission
Heating can directly reduce the consumption of other traditional energies, while may also reach up the purpose of waste utilization, be resource regeneration benefit
With, develop a circular economy, build a conservation-minded society, the important measures of friendly environment.
Water resource heat pump is the states of matter circulation change by the agent of heat pump unit internal refrigeration storage, and winter absorbs heat from spent hot water
Amount, after heat pump unit heats up, to building heat supplying.
Water resource heat pump advantage:
1, water source heat pump units, winter utilizes waste heat water source heat pump heating, saves the occupied area of boiler room；
2, since heating for residential area and the heating of life water etc. need energy consumption, if causing the energy again by direct electric heating
Waste could more effectively utilize electric energy using water resource heat pump heat supply and heating；
3, using water source heat pump technology heat supply heating, to atmosphere and environment without any dye, and also it is energy-efficient, belong to green
Environmental protection technology and device meet the fundamental policies of current China's energy, environmental protection；
Currently, most cities of the water source heat pump system in China have been obtained promoting and applied, and such as: Beijing, Tianjin, mountain
The ground such as west, Shandong, Shijiazhuang, Xinjiang.
As entire society is energy saving, the raising of environmental consciousness, the application field of water resource heat pump is also constantly extending.
Other than freezing, producing domestic hot-water's application in urban heat supplying, also in food, biochemistry, pharmaceuticals industry, plantation cultivation and agricultural and sideline production
Product field is applied.Should further digging utilization all kinds of reproducible spent hot water's heat sources, improve and promote water resource heat pump
Technology develops towards conservation-minded society is established.
Currently, water resource heat pump has obtained the generally approval of society, and the newly-built water resource heat pump engineering in various regions is more and more, but
Be a new problem occurred: water resource heat pump one-time investment is relatively high, and equipment electricity consumption is bigger, significantly limits water source
The further genralrlization of heat pump.
Summary of the invention
For existing water resource heat pump high investment, electricity consumption is larger, and the present invention provides a kind of water resource heat pump, its investment and
Electricity consumption is all smaller.
A kind of water resource heat pump, it is characterised in that: its structure includes: hot waste water evaporator, low-temperature wastewater evaporator, steams
Vapour injector, condenser, pump, valve and several pipelines；
Hot waste water evaporator is a horizontal shell and tube exchanger, and 80~90 DEG C of high temperature waste hot water flows in pipe
Heat release, heat exchanger tube are outside heat pump medium freon, and freon is flowed out by thermal evaporation by venthole；
Low-temperature wastewater evaporator is a horizontal shell and tube exchanger, is that 30~40 DEG C of low temperature is useless in its heat exchanger tube
Hot water, by thermal evaporation, the steam of generation flows out the heat pump medium freon outside pipe from venthole；
The freon steam of hot waste water evaporator outflow enters steam jet ejector as driving steam, sprays by injector
Mouth injection, the freon steam of injection low-temperature wastewater evaporator enter condenser after the two mixing boosting；
The heat release of freon steam condensation is flowed out after being heated to recirculated water, recirculated water to heat user heat supply in condenser；
The freon condensation water generated within the condenser, a part is by pump supply hot waste water evaporator as supplement
Liquid, another part are sent to low-temperature wastewater evaporator as replenisher by throttle valve.
Detailed description of the invention
Fig. 1 is water resource heat pump embodiment overall pattern of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples, present invention is further described in detail.
Fig. 1 gives water resource heat pump embodiment overall pattern of the present invention.
Water resource heat pump embodiment of the present invention, its overall structure include: hot waste water evaporator 100, low-temperature wastewater evaporation
Device 200, steam jet ejector 300, condenser 400, pump, valve and several pipelines.
80~90 DEG C of high temperature waste hot water under normal pressure, by water inlet 105, into hot waste water evaporator 100.High temperature
Waste water evaporator 100 is a horizontal shell and tube exchanger, and hot waste water flows heat release in heat exchanger tube, then from water outlet
110 outflows.It is heat pump medium freon outside 100 heat exchanger tube of hot waste water evaporator, heat pump medium is passed through venthole by thermal evaporation
130 outflows.
Low-temperature wastewater evaporator 200 extracts heat from 30~40 DEG C of low temperature waste heat water, it is a horizontal package
Formula heat exchanger.Low temperature waste heat water in its heat exchanger tube, low temperature waste heat water is flowed into from water inlet 205, to pipe outside heat pump medium
The steam of freon heating, freon evaporation, generation is flowed out from venthole 230.Low temperature waste heat water heat release in heat exchanger tube cools down
Afterwards, it is flowed out from water outlet 210.
The freon steam flowed out from hot waste water evaporator 100 is used as driving steam into steam jet ejector 300, it
It is sprayed by injector nozzle, generates low-voltage space, the freon steam of injection low-temperature wastewater evaporator 200, the two mixing rises
After pressure, into condenser 400.
In condenser 400, to recirculated water, recirculated water is about heated for the freon steam condensation heat release come from injector
To 50~60 DEG C, recirculated water enters from water inlet 405, flows out after being heated from discharge outlet 410, and recirculated water is to heat user heat supply.
The freon condensation water generated in condenser 400, a part supply hot waste water evaporator 100 by pump 350,
As replenisher；Another part is sent to low-temperature wastewater evaporator 200 by throttle valve 250, as replenisher.
