Accompanying drawing explanation
The structural representation of a kind of draining waste-heat recovery device that Fig. 1 provides for this utility model one embodiment.
Detailed description of the invention
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of draining waste-heat recovery device that the present embodiment provides, it is connected with boiler 1, including: hot water outlet pipe 2, cold water mozzle, preheating cold water pipe, spent hot water's drain pipe 9, spent hot water's cistern 10 and water mixing valve 11, wherein, described boiler 1 is Household hot water tank or industrial hot water case.
Described hot water outlet pipe 2 is connected at the hot water outlet of described boiler 1;Described cold water mozzle includes that cold water mixes the cold water filling pipe 3 at water pipe 4, tee T 8 and the cold water inlet being connected to described boiler 1, described cold water mixes one end of water pipe 4 and connects described cold water filling pipe 3 by described tee T 8, and the other end connects described hot water outlet pipe 2 by described water mixing valve 11;
Described preheating cold water pipe includes the cold water inlet 7 being sequentially connected with, spiral economizer bank 6, preheats outlet pipe 5, and described preheating outlet pipe 5 mixes water pipe 4 by described tee T 8 with described cold water filling pipe 3 and cold water and is connected;Described spiral economizer bank 6 is wrapped in outside the body of described spent hot water's drain pipe 9, and described spent hot water's drain pipe 9 is connected with the outlet of described spent hot water's cistern 10.
Understandable, when water mixing valve 11 is positioned to out the position of hot water, hot water is flowed out by hot water outlet pipe 2 from boiler 1, and cold water enters boiler 1 after sequentially passing through cold water inlet 7, spiral economizer bank 6, preheating outlet pipe 5 and cold water filling pipe 3;If it is higher by water mixing valve 11 hot water water temperature out, user can pass through regulating mixed water valve 11, allow cold water sequentially pass through after cold water inlet 7, spiral economizer bank 6, preheating outlet pipe 5 and cold water mix water pipe 4 mix with from hot water outlet pipe 2 hot water out, to realize lower water temperature.The used spent hot water of user is stored in spent hot water's cistern 10, when spent hot water is flowed out through spent hot water's drain pipe 9, owing to spiral economizer bank 6 is wrapped in outside the body of spent hot water's drain pipe 9, so the cold water in spiral economizer bank 6 and the spent hot water in spent hot water's drain pipe 9 can carry out heat exchange, so that the water temperature in spiral economizer bank 6 raises, realizing the cold water to entering in boiler 1 to preheat, the water reduced in boiler is heated to the energy needed for preset temperature.
Additionally, this draining waste-heat recovery device provided due to this utility model is mounted on existing Household hot water tank or the water supply of industrial hot water case and outlet pipe circuit, only need to change cold water draft tube structure, and cold water mozzle is connected can realize with preheating cold water pipe, therefore this utility model provide this draining waste-heat recovery device simple in construction, easy for installation, cost of investment is low, floor space is little, is more easy to popularize.Preferably, the water outlet of described spent hot water's cistern 10 is provided with moveable closed cover 13.
Movably seal lid it is understood that arrange, spent hot water can be made user needs hot water when again to flow out through spent hot water's drain pipe, the cold water entered in boiler is preheated, it is achieved i.e. heat i.e. use, improve the utilization rate of spent hot water's heat energy.
Preferably, described spent hot water's cistern 10 is arranged at the outlet 12 of described water mixing valve 11.
It is understood that spent hot water's cistern is arranged on the water outlet of water mixing valve, the waste water being finished can flow directly into spent hot water's cistern, saves the carrying spent hot water manpower consumption to spent hot water's cistern.
