The reclaimed water circulating system includes an intake pipe and a drainage pipe which are connected with a heat exchanger, an intake port of the intake pipe is arranged in a reclaimed water discharge pipe or a reservoir of a sewage treatment plant, a drainage port of the drainage pipe is positioned at the downstream of the intake port, and the intake pipe and the drainage pipe are respectively provided with water inlet pumps and drainage pumps.
Description
Technical field
The utility model relates to heat pump, particularly a kind of middle water resource heat pump.
Background technology
Heat pump is under the dragging of high potential, heat is flowed to the technology of high-order thermal source from low level heat energy.It can be converted into available high potential to the low grade heat energy that can not directly utilize, thereby reaches the purpose of saving part high potential (coal, oil, natural gas, electric energy etc.).At present, utilize the heat pump in the native sewage water to mainly contain two kinds, first kind of heat pump handled native sewage water through the machine that deters after, by heat exchanger the low-grade energy in the native sewage water is transferred in intermediary's water in intermediary's water circulation system, intermediary's water enters user's end systems such as air-conditioner host.The sewage of second kind of heat pump directly enters evaporimeter, saves the input of secondary heat exchange device and secondary intermediary water-circulating pump, and this system requires harsh to material.
Because the particularity of sewage quality, make heat exchanger in heat pump condition of work very severe, the especially heat pump.When effluent stream during, cause phenomenons such as heat exchanger surface fouling, obstruction or even corrosion easily through heat exchanger.Because the existence of these phenomenons.Make heat transfer efficiency, the service life of heat exchanger reduce, the flow resistance of fluid strengthens.
Summary of the invention
The technical problem that the utility model solves provides that a kind of work operating mode is simple, long service life and middle water resource heat pump with low cost.
For solving the problems of the technologies described above, water resource heat pump comprises middle water circulation system, intermediary's water circulation system and the user's end system that connects successively in of the present utility model, water circulation system comprises intake pipe and the drainpipe that is connected with heat exchanger in described, the intake of intake pipe is arranged in the middle water discharge spout or tank of sewage treatment plant, the discharge outlet of drainpipe is positioned at the downstream of intake, and intake pipe and drainpipe are provided with intake pump and draining pump respectively.
The intake of intake pipe is arranged in the middle water discharge spout or tank of sewage treatment plant, can avoid hot sewage directly to enter heat pump, only needs at the intake place of water intake conduit screen pack to be set in case of necessity and gets final product, and makes the designs simplification of heat pump, and cost reduces.Because the middle water discharge standard of sewage treatment plant has all reached the related standards of national regulation, water quality is better, can not block, problems such as fouling or corrosion pipeline, guaranteed the stability of system's operation, and operating cost reduces.
Description of drawings
Below in conjunction with specification drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
Among the figure: water circulation system in 1,2 intermediary's water circulation systems, 3 user's end systems, 4 intake pumps, 5 draining pumps, 6 immersible pumps, 7 heat exchangers, 8 screen packs, 9 air-conditioner hosts, 10 tanks, 11 intake pipes, 12 drainpipes.
The specific embodiment
Middle water resource heat pump as described in Figure 1, water circulation system 1, intermediary's water circulation system 2 and user's end system 3 in comprising, water circulation system 1 links to each other by heat exchanger 7 with intermediary water circulation system 2 in described, middle water and intermediary's water carry out heat exchange in heat exchanger 7, the low-grade energy of middle water is transferred in intermediary's water.Intermediary's water circulation system 2 is connected by air-conditioner host 9 with user's end system 3, and in air-conditioner host 9, intermediary's water and air carries out heat exchange.During winter, air-conditioner host 9 can heat, during summer.Air-conditioner host 9 can freeze.Certainly air-conditioner host also can substitute with other heat transmission equipment, for example, and heating heater unit etc.
Middle water circulation system 1 comprises intake pipe 11 and the drainpipe 12 that is connected with heat exchanger 7, and the intake of intake pipe 11 is arranged in the middle water discharge spout road or second pond 10 of sewage treatment plant.The delivery port of intake pipe 11 is connected with the water inlet of heat exchanger 7, and intake pump 4 is set on the intake pipe 11, and intake pump 4 pumps into middle water in the heat exchanger 7.Middle water out after the heat exchange of heat exchanger 7 is communicated with drainpipe 12, and the discharge outlet of drainpipe 12 is positioned at the downstream of intake, and the distance of discharge outlet and intake is advisable with the middle coolant-temperature gage that draining does not influence the intake place.Draining pump 5 is set on the drainpipe 12.
The intake of intake pipe 11 is arranged in the middle water discharge spout road or second pond of sewage treatment plant, can avoid hot sewage directly to enter heat pump, does not need the filter of sewage source heat pump, makes the designs simplification of whole system, and cost reduces, and stability improves.Because the middle water discharge standard of sewage treatment plant has all reached the related standards of national regulation, water quality is better, can not block, problem such as fouling or corrosion pipeline, the requirement of water circulation system 1 heat exchanging device 7, intake pipe 11 and drainpipe 12 reduces in whole, has further reduced cost and operation and maintenance cost.
As further improvement of the utility model,, immersible pump 6 is set near being preferably in the intake of intake pipe 11, with the needs of water circulation system water intaking lift in better meeting if middle water source is a second pond 10.For the obturator in the water in further removing, the intake of intake pipe 11 is installed screen pack 8, has further improved the stability of system.
