Abstract

The invention supplies a reasonable pipeline project and adding water source heat pump technology to form resource recycling ecodistrict. The drainage pipeline system has three groups of water intake pipeline, two groups of water outlet pipeline and adopts water source heat pump technology. In the rest heat recycling process, the temperature of water in water source heat pump would decrease to 5 degree centigrade and sending the cool water to air condition system to solve the summer air condition problem. The recycled water contains plenty heat energy that would be used as heat resource for living hot water. The advantages of the invention are that it makes the energy efficiency rate reach 1:8, and it saves water energy, electric energy and the washroom would uneasy to generate odor.

Description

A kind of water circulation use system of ecodistrict

Technical field

Patent of the present invention relates to the resource-cycle ecological community that utilizes water source heat pump technology to transform.

Background technology

At present, the living water use of city ordinarily resident sub-district is from Running-water Company.After tap water enters the user, be dispensed to kitchen, washroom and other water place by running water pipe.Addle after the use is discharged by sewer, no longer utilizes.Water supply is adopted two control with draining; Resident's air-conditioning uses separate type air conditioner mostly, adopts electric refrigeration modes, and its Energy Efficiency Ratio is generally 2.9～3.7; The resident uses hot water generally to obtain by gas water heater or electric water heater.

There is following problem in such sub-district: 1, waste water resource: the sub-district water system adopts single-tube water, fails to provide according to different water occasions the water of different qualities.And not to reclaiming with the waste water of crossing.Cause water resource waste.2, cause air pollution: because drainage system adopts single tube system, same sewer pipe mixed flush the toilet water and bathing water etc.If when flush the toilet just at the right time with use hot water (as bathing) simultaneously (different user) in same unit carry out water is heated its stink is distributed in a large number because hot water is flushed the toilet after meeting with the water of flushing the toilet.The exhaust opening of attic can make the sewer pipe internal pressure increase as can not in time discharging, and foul smell just from the floor drain ejection, just produced a large amount of stinks in the washroom, causes air pollution.3, waste energy: contain a large amount of waste heats in the resident living waste water and fail to be used, used relatively poor electric water heater of economy and air source air conditioner in the resident living.

Summary of the invention

For the water wasting that overcomes common biotope pipe-line system, the shortcoming of taking electricity, generation stink, the invention provides a kind of more reasonably pipeline solution, thus and adding water source heat pump technology formation resource-cycle ecological community.

The technical solution adopted for the present invention to solve the technical problems is: the solution that adopts plumbing five control and water and Integrated Energy to reclaim.

(1) plumbing five control

Three pipes feed water: 1, running water pipe-clean water, supply with the place that kitchen, washing, shower, laundry etc. need the cleaning water source.2, the middle water (cold water) of middle water pipe-recovery, supply with flush the toilet, keep a public place clean, the place not high such as irrigation to the water quality requirements, flushing the toilet with cold water is difficult for producing stink.3, the place that kitchen, washing, shower, laundry etc. need hot water is supplied with in hot-water line-central hot feed.

Two pipes of draining: 1, water pipe-discarded sewage, flush the toilet, the difficult waste water that reclaims such as kitchen.This root water pipe directly enters the septic tank of particular design, can extract fertilizer and so both reduce whole water treatment burden from the pond, can form the ecological agriculture to the crops fertilising again.2, return water pipe-row is to middle water treatment system, recyclable sewage, the waste water of washing one's hands and face, take a shower, do washing, keeping a public place clean etc. and easily reclaiming.

Above measure can solve waste water reclaim again with and following moisture from the problem of (avoiding producing stink).

(2) water and Integrated Energy reclaim

1, waste water reclaims

The waste water that collection is produced by places such as washing one's hands and face, take a shower, do washing, keep a public place clean, after filtration, operations such as aeration, dosing produce recycling in water.In the daily life sewage 80% recyclablely used again.The middle water water temperature that reclaims is approximately about 25 ℃.Middle water is delivered to waste-heat recovery device through utilidor and carries out waste heat recovery.

2, waste heat recovery

Contain a large amount of heat energy in the middle water that reclaims, waste heat can be regained thermal source as the preparation domestic hot-water.Adopt water source heat pump units therefrom to extract heat energy in the water tank, the water temperature in the hot water cylinder is promoted to about 40～45 ℃.Then with water pump with delivery to the hot water user.

3, Yu Lengzai uses (cold recovery)

In the waste heat recovery process, the water temperature in the middle water tank can be reduced to about 5 ℃.This cold water is sent into air-conditioning system, can solve the summer air-conditioning problem of certain customers in the sub-district.

By the invention has the beneficial effects as follows, Energy Efficiency Ratio is reached more than the 1:8, saved water energy, electric energy and made the lavatory be difficult for producing stink.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is a schematic diagram of the present invention.

Among Fig. 1: 1. tap water outer net, 2. tap water feedwater, 3. tap water water service pipe, 4. kitchen, 5. sewer pipe, 6. septic tank, 7. fertilizer, 8. sewer pipe net, 9. washing, 10. shower, 11. hot water water service pipes, 12. laundries, 13. flush the toilet, 14. irrigate, and 15. keep a public place clean, 16. return water pipes, 17. middle water treatment, 18. heat reclamation type source pump, 19. refrigeration air-conditioners, 20. hot water reclaims, and 21, central authorities' feedwater, 22, middle water water service pipe.

The specific embodiment

In Fig. 1, tap water outer net 1 send clean water by tap water water service pipe 3 to the sub-district, and supply with kitchen 4, washing 9, take a shower 10, laundry 12 etc. needs the place at cleaning water source.Flush the toilet 13, the difficult waste water that reclaims such as kitchen 4, directly enter the septic tank 6 of particular design by sewer pipe 5, can extract fertilizer 7 and so both reduce whole water treatment burden from the pond, can form the ecological agriculture to the crops fertilising again, the water of carrying behind the fertilizer enters sewer pipe net 8.Washing 9, take a shower 10, laundry 12, the waste water that easily reclaim such as 15 of keeping a public place clean enter by return water pipe 16 in water treatment 17 recycled.The middle water water temperature that reclaims is approximately 25 ℃, middle water is delivered to heat reclamation type source pump 18 through utilidor, adopt water source heat pump units therefrom to extract heat energy in the water, water temperature in the hot water cylinder is promoted to about 40～45 ℃, then with water pump by hot water water service pipe 11 with delivery to the hot water user, as kitchen 4, washing 9, take a shower 10, laundry 12.In the waste heat recovery process, the water temperature in the middle water tank can be reduced to about 5 ℃ by water resource heat pump, and wherein part cold water is sent into refrigeration air-conditioner 19 systems, can solve the summer air-conditioning problem of certain customers in the sub-district.Water is used for flushing the toilet 13, irrigates 14 and keep a public place clean 15 by middle water water service pipe 22 in all the other parts.So just formed resource-cycle ecological community.
