Embodiment
As shown in Figure 2, the utility model one has 3 kinds of operational modes, below according to Fig. 2, respectively three kinds of patterns is discussed in detail:
One, the temperature of solar water heater (sensor L3) is higher than 62 ℃, and the temperature of marsh-gas fermentation tank (sensor L2) is during lower than 34.8 ℃, and at this moment needing to marsh-gas fermentation tank provides heat, has 2 kinds of circulation routes:
(1), when the temperature of hot water snubber 4 (sensor L1) is more than or equal to 60 ℃, its circulation route is:
Hot water snubber 4 → recycle pump 14 → magnetic valve V4 → votator 5 → magnetic valve V5 → magnetic valve V2 → hot water snubber 4
Now, magnetic valve V1, V3, V6 close, and have cut off the circulation of hot water snubber 4 with solar energy hot water tank 1, and recirculated water directly enters votator 5 by hot water snubber 4 and circulated.Thereby water temperature in hot water snubber 4 is reduced, and the temperature of marsh-gas fermentation tank 6 interior feed liquids raises.
(2), when the temperature of hot water snubber 4 (sensor L1) is lower than 58 ℃, its circulation route is:
Hot water snubber 4 → recycle pump 14 → magnetic valve V6 → magnetic valve V3 → solar water heater 1 → magnetic valve V1 → hot water snubber 4
Now, magnetic valve V1, V3, V6 open, UNICOM hot water snubber 4 circulation with solar energy hot water tank 1, recirculated water is circulated by solar water heater 1, and water temperature in hot water snubber 4 is raise.Only have after the temperature of hot water snubber 4 interior water reaches 60 ℃, ON cycle route (1) is that marsh-gas fermentation tank 6 improves heat again.
Two, lower than 62 ℃, the temperature of fermentor tank 6 (sensor L2) is during lower than 34.8 ℃ higher than 40 ℃ for the temperature of solar energy hot water tank 1 (sensor L3), and now also needing to marsh-gas fermentation tank 6 provides heat, and its circulation route is:
Hot water snubber 4 → recycle pump 14 → magnetic valve V4 → votator 5 → magnetic valve V5 → magnetic valve V3 → solar water heater 4 → magnetic valve V1 → hot water snubber 4
Now, magnetic valve V1, V3, V4 and V5 open, UNICOM the circulation of votator 5, hot water snubber 4 with solar energy hot water tank 1, directly utilize the heat heating biogas fermentor tank 6 in solar water heater, impel feed temperature in fermentor tank to raise.
Three, the temperature of marsh-gas fermentation tank 6 (sensor L2) higher than 35.2 ℃ (2 o'clock, now marsh-gas fermentation tank 6 does not need the heat heating, and magnetic valve V1, V2, V3, V4, V5, V6 all close, and recycle pump 14 quits work, avoid the recycle pump stream time long, saves energy.
In addition, when the temperature of solar energy hot water tank 1 (sensor L3), during lower than 40 ℃, the heat that solar heat collector is collected can not meet the demand of feed liquid to heat, and magnetic valve V1, V2, V3, V4, V5, V6 also will close, recycle pump 14 is out of service, realizes the operational mode at night of system.
Cloudy day or snow day, can carry out boosting by the interior electric heating tube of manual starting solar water heating system, so that whole system is normally moved.
In summer, envrionment temperature is higher, and marsh-gas fermentation tank 6 does not adopt solar heating normally to ferment, so the hot water in solar water heater can directly offer the user and use, and meets the needs of user to the domestic hot-water.
