Background technology

The energy, water resource, environment is the eternal theme of human survival and development.Energy-conservation, water saving, environmental protection are the significant challenge that the current whole mankind faces.Ground source heat pump technology and technology of middle water recycle and energy-conservation, water saving, environmental protection have close relationship.

One, at first sets forth ground source heat pump technology.

Ground source heat pump technology is born in the fifties in last century, enters China the nineties.It is a kind of HVAC technology of energy-saving and environmental protection.It will lie in the earth surface geothermal using resource---in the ground body of the face of land, in the underground water; In the natural surface water such as river, river, lake, sea, the low-grade energy in municipal sewage and the waste water by heat pump techniques, promotes and is high-grade energy, but both coolings, but heat supply again.

Because the temperature of shallow surface geothermal energy resources, relatively stable throughout the year, winter is than environment temperature height, summer is lower than environment temperature, having good temperature characterisitic, is the good cold/heat source of water source heat pump units, for water source heat pump units provides optimal operating condition, thereby geothermal heat pump air-conditioner has higher efficient than traditional air-conditioning, and it is high by about 40% that Energy Efficiency Ratio COP value is generally wanted.And it is any pollutant of environmental emission towards periphery not, therefore, and not only energy-conservation but also environmental protection.The shallow surface geothermal energy resources have a large capacity and a wide range, and circular regeneration is inexhaustible, are a kind of regenerative resources of cleaning.So ground source heat pump technology is one and has revolutionary advanced technology to have huge energy-saving benefit, economic benefit, environmental benefit, has vast potential for future development.Particularly in recent years, increasingly serious energy situation, environmental problem makes ground source heat pump technology be subjected to people's extensive concern, has obtained development at full speed.

Dissimilar according to face of land geothermal using resource, earth-source hot-pump system roughly is divided into four kinds of forms:

1. pipe laying earth-source hot-pump system.

It is in shallow surface ground body, the landfill heat transfer tube, and ground pipe laying and the coupling of ground body form ground body heat-exchange system.The ground pipe laying links to each other with water source heat pump units, forms closed circuit, and the heat transfer medium that flows in the ground pipe laying is cold/heat medium water, and cold/heat medium water and ground body carry out exchange heat, during refrigeration, to ground body release heat, when heating, from ground body draw heat.Flow in the ground pipe laying heat transfer medium---cold/heat medium water is the source water in the earth-source hot-pump system.Ground pipe laying heat-exchange system divides two kinds of forms, and a kind of to be heat transfer tube be vertically mounted on the heat-exchange system of pipe laying vertically in the vertical shaft with U-shaped or other patterns, and as shown in Figure 1, wherein 131 is water source heat pump units, and 132 is water inlet pipe, and 133 is return pipe.Another kind is that the heat transfer tube level is installed in the heat-exchange system of pipe laying flatly in the trench, and as shown in Figure 2, wherein 131 is water source heat pump units, and 132 is water inlet pipe, and 133 is return pipe.Form commonly used is pipe laying heat pump vertically in the engineering.

2. underground water earth-source hot-pump system

It is to dig pumped well and recharge well in the depth layer of the face of land, by submersible pump groundwater abstraction from pumped well, offers water source heat pump units, after the heat exchange, by recharge well, recharges underground.The underground water heat-exchange system has two kinds of forms usually, and a kind of is direct underground water heat-exchange system, and another kind is indirect underground water heat-exchange system.In direct underground water heat-exchange system, underground water is delivered directly to water source heat pump units after treatment, and after the heat exchange, underground water by recharge well, recharges underground again.Underground water is the source water in the earth-source hot-pump system, and as shown in Figure 3, wherein 131 is water source heat pump units, and 132 is water inlet pipe, and 133 is return pipe, and 134 is water treatment facilities.In indirect underground water heat-exchange system, underground water and water source heat pump units are separated by Intermediate Heat Exchanger, and underground water is a water, and underground water is transformed into heat in the secondary water by Intermediate Heat Exchanger.After the heat exchange, underground water recharges underground by recharge well.Secondary water links to each other with water source heat pump units, forms closed circuit, and secondary water is the source water in the earth-source hot-pump system, and as shown in Figure 4, wherein 131 is water source heat pump units, and 132 is water inlet pipe, and 133 is return pipe, and 134 is water treatment facilities, and 135 is Intermediate Heat Exchanger.

3. surface water earth-source hot-pump system

Be the cold/heat source of earth-source hot-pump system with natural surface water such as the suitable river of temperature, river, lake, seas.The surface water heat-exchange system has two kinds of forms usually, and a kind of is open system, and another kind is closed system.In open system, river, river, lake, seawater are delivered directly to water source heat pump units after treatment, after the heat exchange, directly flow back in the former water body, and river, river, lake, seawater are the source water in the earth-source hot-pump system.As shown in Figure 5, wherein 131 is water source heat pump units, and 132 is water inlet pipe, and 133 is return pipe, and 134 is water treatment facilities.In closed system, divide two kinds of forms again, a kind of is diving cloth tubular type, another kind is middle heat exchange type.In diving cloth tubular type heat-exchange system, heat transfer tube is laid on the underwater of river, river, lake, seawater, and with the water body coupling, the outer water body of the heat transfer medium in the conduit---cold/heat medium water and pipe carries out interchange of heat.The diving conduit links to each other with water source heat pump units, and the heat transfer medium-cold/heat medium water in the diving conduit is source water.As shown in Figure 6, wherein 131 is water source heat pump units, and 132 is water inlet pipe, and 133 is return pipe.In middle heat exchange type system, river, river, lake, seawater and water source heat pump units are separated by Intermediate Heat Exchanger.River, river, lake, seawater are a water, by Intermediate Heat Exchanger heat are transformed in the secondary water.River after the heat exchange, river, lake, seawater flow back in the former water body, and secondary water links to each other with water source heat pump units, form closed circuit, and secondary water is the source water in the earth-source hot-pump system.As shown in Figure 7, wherein 131 is water source heat pump units, and 132 is water inlet pipe, and 133 is return pipe, and 134 is water treatment facilities, and 135 is Intermediate Heat Exchanger.

4. source of sewage earth-source hot-pump system

Municipal sewage is cool in summer and warm in winter, and temperature is constant relatively, and reserves are huge, is a kind of cold/heat source of high-quality.The source of sewage earth-source hot-pump system has three kinds of forms.A kind of is direct source of sewage earth-source hot-pump system, is referred to as the native sewage water source earth-source hot-pump system again; Another kind is indirect source of sewage earth-source hot-pump system; The third is regenerated water---middle water earth-source hot-pump system.In direct source of sewage earth-source hot-pump system, native sewage water after treatment, be delivered directly to water source heat pump units, after the heat exchange, directly flow back in the raw sewage water body, native sewage water is the source water in the earth-source hot-pump system, as shown in Figure 8, wherein 131 is water source heat pump units, and 132 is water inlet pipe, 133 is return pipe, and 134 is water treatment facilities.In indirect source of sewage earth-source hot-pump system, native sewage water separates by Intermediate Heat Exchanger with water source heat pump units, and native sewage water is a water, and by Intermediate Heat Exchanger, to secondary water, one time water flows back in the raw sewage water body again with thermal power transfer.Secondary water links to each other with water source heat pump units, circular flow, and secondary water is the source water in the earth-source hot-pump system, and as shown in Figure 9, wherein 131 is water source heat pump units, and 132 is water inlet pipe, and 133 is return pipe, and 134 is water treatment facilities, and 135 is Intermediate Heat Exchanger.Becoming regenerated water after the municipal sewage treatment---middle water, it has the same temperature characterisitic of native sewage water, and water quality is good, can directly link to each other with water source heat pump units.Middle water is the source water in the earth-source hot-pump system, and as shown in figure 10, wherein, 131 is water source heat pump units, and 132 is water inlet pipe, and 133 is return pipe, and 136 is sewage, waste water, and 137 is middle water treatment facilities.

The transmission medium of cold/heat source-source water can be referred to as to call water source again in the earth-source hot-pump system.

At present, the development ﹠ construction of earth source heat pump mainly are to carry out with the form of monomer engineering.So-called monomer engineering is exactly single building, according to the cold/heat requirement requirement of ambient conditions, resources supplIes, hydrogeological conditions and the building of himself site itself, adopts a certain earth-source hot-pump system, establishes one's own system independent operating.The development ﹠ construction pattern of this monomer engineering exists many defectives, hampers the development of earth source heat pump.Its major defect is:

1. the utilization of any one technology all is with good conditionsi, and earth source heat pump is no exception.For example: adopt the ground pipe laying earth-source hot-pump system pipe laying of need digging a well, quantity and the well spacing of source, ground well all have certain requirements.Therefore, it at first requires the place of certain area.And in the city the intensive area of building, then such place can not be arranged.Therefore, in the old town, ground pipe laying earth source heat pump form just can not be adopted in downtown area, building compact district.Again for example, adopt the surface water earth-source hot-pump system, at first require building to answer neighbour river, river, lake, sea; Adopt the underground water earth-source hot-pump system to require the on-site phreatic water quality of building, temperature, discharge, geologic structure all will satisfy the service requirement of water source heat pump units; Adopt the source of sewage earth-source hot-pump system to require near the building trunk sewer of enough discharge etc. is arranged.

Therefore, can a construction project adopt earth-source hot-pump system, adopt the earth-source hot-pump system of that a kind of form, depend on its ambient conditions, resources supplIes, weather conditions, hydrogeological conditions, execution conditions etc., these requirements, for the monomer engineering, be a restriction greatly, make a lot of construction projects can't adopt earth-source hot-pump system.Therefore, the exploitation form of monomer engineering is greatly limited the development and use of earth source heat pump.

2. ground source heat pump technology is a multiple subject crossing, and the integrated technology of multiple professional combination is a complicated system engineering.Therefore, the development ﹠ construction of earth source heat pump must be carried out strict engineering construction codes and standards based on science and technology.But the monomer engineering, the engineering system that this dispersion is isolated is difficult to satisfy this requirement.At present, all there are the following problems for most of engineerings:

1.. ignore the engineering hydrogeology prospecting in early stage, lack collection, arrangement and the analysis of meteorological data, the accurate investigation of heat resource and science assessment scantily lacks overall planning.Be brought about in a rush unordered exploitation, unchecked construction.

2.. energy balance is the principle that the earth source heat pump development ﹠ construction should be followed, and system wants basis equalization to the heat of underground discharge with the heat from underground taking-up, otherwise, if an area is in the energy non-equilibrium state for a long time, will destroy its thermal field.Or make the ground body form " heat island " or " cool island ", or surface water quality is worsened, cause environment pollution; Or phreatic water temperature, water quality, discharge are damaged, even cause geological disaster etc.

3.. on construction quality, the monomer engineering lacks strict engineering management, and it is lack of standardization to construct.If any the underground water earth-source hot-pump system, only draw water and do not recharge; The ground pipe laying earth-source hot-pump system that has is not according to standard grouting backfill; Construction team, very different, construction quality can't guarantee, stay a lot of hidden dangers in project etc.

The ecosystem geothermal energy resource in an area is weather, the geology transition that process is very long, from the sky to the face of land, from the face of land to underground, the energy field of a stable harmony that breeds.It is an organic whole, is the system of interrelated a, circular regeneration, must act on the attitude of science to its development and use, and in strict accordance with objective law, scientific development is built in order.

Set up a science, efficient and stable, advanced and practical, the earth-source hot-pump system of sustainable development is pendulum urgent task very in face of people.

Two, following elaboration technology of middle water recycle.

Water is Source of life.The celestial body that we live, though moisture storage capacity is very abundant, the land freshwater resources are extremely limited.Since the fifties in last century, the rising suddenly and sharply of population, the fast development of industry, climate warming, reasons such as environment pollution cause the water resource worsening shortages, and human existence and development in serious threat.China is the most deficient country of water resource, and water resources crisis has had a strong impact on the sustainable development of China's economy and society.

The water resource that solves worsening shortages is the huge challenge that people face.In numerous counter-measures, sewerage treatment, middle water reuse are valid approach.After middle water is advanced treatment of wastewater, reach specified standard, the undrinkable water that can use within the specific limits.It can be widely used in: lavatory flushing, green land irrigation, car washing water, water for fire, water-use for environment, agricultural water, industry cooling, aspects such as municipal construction.According to statistics, 80 ﹪ of urban water use total amount have changed into sewage, and sewage is after advanced treating, and 70 ﹪ are convertible into middle water, and namely urban water use total amount over half is convertible into middle water.According to statistics, whole nation annual output sewage total amount is about 50,000,000,000 tons at present, can produce water in about 28,000,000,000 tons.This is a huge resource.It provides an enormous amount for the city, and cost is lower, and transmission ﹠ distribution are second water source easily.Simultaneously, it has greatly promoted the development of municipal sewage treatment, has eliminated the pollution of municipal sewage to environment effectively.Sewerage treatment, middle water reuse was was both increased income and decreased expenditure, and protected environment again, had the strategic importance of national century development.

Sewerage treatment, middle water reuse, remarkable benefit, significant, ought to be promoted widely and be adopted.But at present middle water reuse is undesirable.Mainly be that middle water reclamation rate is low, range of application is not extensive.According to estimates, present Waste water utilization rate is less than 20 ﹪.This just forms, on the one hand, and city serious water shortage, the health and the daily life that jeopardize people, influence society, sustainable development of economy; On the other hand, middle water can not obtain reuse, and is a large amount of, and precious water resource has slatterned in vain.Cause the main following points of reason of this contradiction situation:

1. recognize and look mistaken ideas.Water is from sewage in thinking, unclean, centering water water quality is suspected, and uses enthusiasm not high.

2. price.At present because technology and scale problem, in aquatic product and cost of transportation than higher, not obvious with the tap water price difference, thus people lack produce and use in the interests of water drive.

3. water supply network lacks, and water is arranged for not going out.

4. machine-processed.At present, middle water reuse does not have ripe business model.All do not realize industrialization, the marketization from investment, construction, operation, influenced the extensive popularization of middle water, sustainable development.

Middle water reuse is an industry with large-scale production feature.The appropriate scale of operation of water reuse in realizing will realize the full processing of sewage, and the full reuse target of middle water at first must be built a large amount of middle grids.But pipeline network construction is invested hugely, and it is a great problem on the middle water reuse industry development road.

Middle water also has another important characteristic except the basic function with undrinkable water, containing lot of energy in the middle water.As previously mentioned, middle water also is a kind of cold/heat source of earth-source hot-pump system.Middle water is a kind of water resource, also is a kind of energy.This double attribute that middle glassware for drinking water has is a difficult problem that cracks in middle water reuse and the earth source heat pump development ﹠ construction, has started the road of a hope.

Three, existing in prior technology problem

1. existing ground source heat pump technology adopts the construction form of monomer engineering, owing to be subjected to the restriction of the Location geothermal energy resource of building service condition own, a lot of construction projects can't adopt ground source heat pump technology, make earth source heat pump can not become the main product of industry development so far, greatly hinder and limited the large-scale promotion of ground source heat pump technology.

2. existing source heat pump system monolithically is difficult to accomplish energy balance.At cold district, winter heat requirement greater than the refrigeration duty in summer, and in temperature, torrid areas, the refrigeration duty in summer is greater than the heat requirement in winter.Even areal, the building of difference in functionality, cooling and heating load also are different, some industry, items in commerce then need to freeze all the year round or heat, and therefore, monomer engineering cooling and heating load is unbalanced to be objective reality.The monomer engineering often adopts the geothermal energy resource of a certain form, and the self-balancing ability of single geothermal energy resource is very limited, and artificial regulation and control also are very difficult.Therefore, establishing one's own system, under the development mode of the monomer engineering of independent operating, accomplish that energy balance is very difficult.

3. the temperature of cold/heat source is that water source heat pump units is energy-conservation, the key of efficient operation.Requirement to source water inflow temperature during general water source heat pump units optimum condition is: during summer cooling, for well, during Winter heat supply, 10-15 ° of C is good about 25 ° of C.Exceed this scope, exceed low all bad excessively.Slight person, decrease in efficiency does not reach purpose of energy saving.Severe patient, unit breaks down, cisco unity malfunction, even unit outage, systemic breakdown, engineering failure.Existing ground source heat pump technology adopts the exploitation form of monomer engineering, often adopt the geothermal energy resource of single form, and the temperature characterisitic of various forms geothermal energy resource is different.The geothermal energy resource of single form often has limitation, unstability.For example, in colder area, surface water earth-source hot-pump system and ground pipe laying earth-source hot-pump system during summer cooling, can satisfy working condition requirement.But during Winter heat supply, the source coolant-temperature gage is on the low side, and efficient is very low during heat supply, even can not heat supply.So existing earth-source hot-pump system can not guarantee the quality of cold/heat source fully, can not guarantee the energy-saving effect of earth-source hot-pump system, can not guarantee that earth-source hot-pump system continues, operation stably.

4. the construction mode of monomer engineering, project scale is less, and it is often lack of standardization to construct, and workmanship is difficult to guarantee that hidden dangers in project is a lot.Operational efficiency descends, and the engineering Failure cases can be found everywhere, and has a strong impact on the development of ground source heat pump technology.

5. in the prior art, middle water reuse and earth source heat pump adhere to two technical fields separately, and two industries are to have no two related systems.Middle water reuse is sewerage treatment, the development and use of water resource, and middle water is the water source of undrinkable water in the zone.Ground source heat pump technology is the development and use of geothermal using resource, and source water is the cold/heat source of earth-source hot-pump system in the zone.Cutting apart of technology and industrial field makes this composite factor can not obtain comprehensive utilization, takes full advantage of scientific utilization.

6. feasibility economically is the key factor that influences industry development.According to prior art, water reuse and earth source heat pump in developing need to build two pipe networks, three pipelines.Urban pipe network is built, invest huge, engineering complexity, economically very risky.At present, the shortage of pipeline network construction has seriously restricted the development of middle water reuse.Ground source heat pump technology will continue, stablizes, develop healthily, also needs to build a public cold/heat source source grid.And the source grid needs to supply, return two pipelines, and cost of investment is higher.In addition, in non-air-conditioning season, most water source heat pump units are not moved, and the pipe network utilization rate is very low, and running cost can be very high.So pipeline network construction also can become the bottleneck of ground source heat pump technology development.
