Abstract

The utility model relates to a kind of domestic energy-saving hot water supply system based on waste heat recovery.Hot water, with directly entering sewer later, is wasted a large amount of waste heats at present.The external running water in one end of the first water valve in the utility model, the other end is connected with the cold water inlet of heat exchanger, the warm water outlet of heat exchanger is connected with the water inlet of boiler, the delivery port of boiler is connected with fluffy head by the second water valve, under fluffy head, be provided with hot waste water collector, the delivery port of hot waste water collector is connected with the waste water import of heat exchanger, and hot waste water flows out from the wastewater outlet of heat exchanger in heat exchanger with after heat-exchange tube heat-shift.The utility model can reclaim the huge heat of containing in waste water, has energy-saving and emission-reduction, and automaticity is high, shortens the advantages such as heat time.

Description

A kind of domestic energy-saving hot water supply system based on waste heat recovery
Technical field
The utility model belongs to field of energy-saving technology, is specifically related to a kind of domestic energy-saving hot water supply system based on waste heat recovery.
Background technology
Along with socioeconomic development, contemporary society's growth in the living standard, hot water is more and more indispensable in daily life.By its purposes, divide, domestic hot water can be divided into and drinking and non-two classes of drinking.Wherein non-drinking hot water is mainly used in shower, washes one's face and rinses one's mouth etc., and its use is disposable often, and has occupied domestic hot water's the overwhelming majority.Such as conventional shower water, people directly enter sewer often to the processing of shower waste, seldom can consider its waste heat recovery recycling, also similar to the waste heat of washing waste water.Yet its waste heat is still considerable in the waste water after these disposable uses, people have just used the heat of few part wherein, and heat utilization efficiency is lower.Hot waste water directly enters sewer, has both caused the loss of heat, and the heat that waste water discharges simultaneously also can impact surrounding enviroment to a certain extent.Current most family obtains domestic hot-water by electric heater, if high-temperature domestic wastewater is directly entered to sewer, certainly will indirectly cause the waste of electric energy, has increased people's financial burden.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of domestic energy-saving hot water supply system based on waste heat recovery.
The utility model comprises heat exchanger, boiler, hot waste water collector, controller, the first water valve, the second water valve and fluffy head.
The external running water in one end of the first water valve, the other end is connected with the cold water inlet of heat exchanger, the warm water outlet of heat exchanger is connected with the water inlet of boiler, the delivery port of boiler is connected with fluffy head by the second water valve, under fluffy head, be provided with hot waste water collector, the delivery port of hot waste water collector is connected with the waste water import of heat exchanger, and hot waste water flows out from the wastewater outlet of heat exchanger in heat exchanger with after heat-exchange tube heat-shift.
Described heat-exchange tube is spiral surrounding, the cold water inlet that its one end is heat exchanger, the warm water outlet that the other end is heat exchanger.
In described boiler, be provided with temperature sensor and heater, temperature sensor, heater are all connected with controller signals.
The beneficial effects of the utility model are: original domestic hot water's supply system and waste water heat recovering equipment are combined, can not only guarantee the supply of hot water, can also reclaim the huge heat of containing in waste water, greatly reduce heating required energy and the time of cold water, there are energy-saving and emission-reduction, automaticity is high, shortens the advantages such as heat time.
Accompanying drawing explanation
Fig. 1 is system architecture schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, the present embodiment comprises for heating and store the boiler 2 of hot water, for filtering and collect the hot waste water collector 3 of waste water, heat exchanger 1, fluffy 8.The waste water that band has surplus heat is by wastewater outlet 3-1 inflow heat exchanger after hot waste water collector filters collection, and cold water to be heated is from the cold water inlet 1-2 inflow heat exchanger of heat exchanger.Under heat-exchange tube 1-1 effect in heat exchanger, hot waste water and cold water fully carry out heat exchange, heat in waste water is transferred to cold water, cold water is preheated, cold water after preheating flows out from the warm water outlet 1-4 of heat exchanger, enter boiler 2, and cooled waste water is discharged from cooling waste water outlet 1-3, with this, realizes the recovery of hot waste water heat.
Temperature sensor 2-2 and heater 2-1 are housed in boiler, and sensor is connected with controller 5 with heater.User can set leaving water temperature, and controller is by detecting current water temperature and the predefined output water temperature in water tank, and the heating power of control heater, realizes thermostatic control, for user provides the hot water that temperature is suitable.Rotation water valve 6 one end are connected with heat exchanger cold water inlet, and the other end is directly connected with the running water pipe of family, by control, rotate the water source that water valve 6 can switch whole system.Rotation water valve 7 one end are connected with boiler, and the hot water that user uses in boiler by water valve 7, closes water valve 7 while not using hot water.
During use, open water valve 6, cold water in household tap water pipeline enters in heat exchanger, and enter in boiler by pipeline 4, controller measured and feeds back to by temperature sensor in boiler to water temperature, heater heats according to established temperature, open water valve 7, hot water flows out by fluffy head, waste water after use is collected by hot waste water collector, by waste water import, enter in heat exchanger, and the stand-by cold water in heat-exchange tube is preheated, by wastewater outlet, discharge after completing heat exchange.
The utility model combines original domestic hot water's supply system and waste water heat recovering equipment, can not only guarantee the supply of hot water, can also reclaim the huge heat of containing in waste water, greatly reduce heating required energy and the time of cold water, there are energy-saving and emission-reduction, automaticity is high, shortens the advantages such as heat time.
