Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model is made up of geothermal system, counter-infiltration system and oil-field flooding station.Geothermal system is made up of heating equipment cold water pipe 3, heating equipment hot-water line 4, compressor 17, condenser 18 and evaporimeter 19; Counter-infiltration system by increase water pump 6, more medium filter 7, active carbon filter 8, antisludging agent chemicals dosing plant 9, accurate filter 10, high-pressure pump 11, RO film filter 12 and scavenging pump 13, cleaning water tank 14 form.Evaporimeter 19 connects wet well 1 by pipeline; Cool condenser 18, compressor 17 are connected successively with evaporimeter 19 order.Choke valve is provided with between condenser 18 and evaporimeter 19.Condenser 18 and evaporimeter 19 are all connected GEOTHERMAL WATER water inlet pipe 20 and GEOTHERMAL WATER outlet pipe 21 respectively by pipeline.Heating equipment cold water pipe 3 and heating equipment hot-water line 4 are all connected on heating equipment 5.Geothermal system 2 is connected on booster pump 6 by GEOTHERMAL WATER outlet pipe.
More medium filter 7 is provided with between booster pump 6 and active carbon filter 8.Active carbon filter 8 is connected with antisludging agent chemicals dosing plant 9, accurate filter 10 respectively.Accurate filter 10 is connected with RO film filter 12 by high-pressure pump 11.One end of scavenging pump 13 is connected on the pipeline between accurate filter 10 and high-pressure pump 11 by pipeline, the other end is connected on cleaning water tank 14.RO film filter 12 connects domestic water system 16.Cleaning water tank 14 is connected on the wastewater outlet of RO film filter 12.Cleaning water tank 14 connects oil-field flooding station 15.
First earth source heat pump utilizes water pump to extract GEOTHERMAL WATER at the bottom of ground, and GEOTHERMAL WATER flows through evaporimeter, carries out heat exchange, enter into condenser after condensing agent being heated into the gas of HTHP with the condensing agent of the low-temp low-pressure of coming in compressor; The condensing agent gas of HTHP carries out heat exchange with cold water within the condenser, release heat cool water heating is become hot water for.And the low temperature geothermal water after heat release enters into counter-infiltration system; First tentatively filter through more medium filter and active carbon filter in counter-infiltration system, the suspension and the micelle that filter out greater particle size in water make delivery turbidity can reach less than 3 degree, then be the accurate filter of 5 μm through filtering accuracy, filter out the particulate that particle diameter is greater than 5 μm, enter counter-infiltration system to prevent it; Enter into RO film filter 12 after eventually passing high-pressure pump pressurization and carry out desalination and deionization.
Because the water temperature of the GEOTHERMAL WATER after heat exchange in general can at about 30 degree, characteristic due to reverse osmosis membrane is that aquifer yield and salt rejection rate can raise along with the rising of temperature in suitable temperature range, so now will obtain higher aquifer yield and larger salt rejection rate relative to the water desalination of normal temperature.
The last product water of system can directly use as domestic water, also can be transported to oil-field flooding station for recovering the oil to underground flooding.Now because dense water salt content is comparatively large, proportion is more great than the ratio of general fresh water, so can produce higher pressure, the output of oil is strengthened.
Above-mentioned embodiment is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing; the change that those skilled in the art make within the scope of the technical solution of the utility model, remodeling, interpolation or replacement, also all belong to protection domain of the present utility model.
