Detailed description of the invention

This utility model is further described below with reference to embodiment (accompanying drawing):

As it is shown in figure 1, the methane-generating pit for farm household temperature-increasing system with diaphragm type heat-transfer pipe of the present utility model includes thermal source hot water circulation loop, the diaphragm type pipe hot water circulation loop that is arranged in methane-generating pit and methane-generating pit top board; Described thermal source hot water circulation loop includes being built-in with the hot water storage tank 6 of auxiliary electricity consumption thermal-collecting tube 8, by circulation line, control valve and attemperating unit 2 accordingly, solar thermal collector 1 that water circulating pump 3 is connected with hot water storage tank 6 and straw kitchen range chuck hot water apparatus 4; Described diaphragm type pipe hot water circulation loop is connected with hot water storage tank 6 by circulation line, water circulating pump 5 and the corresponding valve that controls.

Diaphragm type heat-transfer pipe 10 in the hot water circulation loop of diaphragm type pipe described in this utility model is to be prepared from (referring to Fig. 2, shown in 3) by inner bulge, shaggy coefficient of expansion aluminum alloy material big, good heat conductivity. Described methane-generating pit top board adopts glass end cap ceiling, and the bottom of methane-generating pit and periphery are provided with the ring-shaped groove filling rice husk, sawdust.

The straw kitchen range chuck hot water apparatus 4 that the system of thermal source hot water circulation loop described in this utility model adopts, it includes the chuck water storage container 4-2 being provided with water inlet 4-1, outlet 6, and 1# stove 4-3,2# cook a meal stove thorax 4-7,2# of stove 4-4,1# that cook a meal that cook a meal cooks a meal stove thorax 4-8; This straw kitchen range chuck hot water apparatus 4 is to utilize straw kitchen range to cook a meal the chuck water storage container 4-2 being arranged in kitchen range burner hearth with waste-heat, provides heat energy (referring to Fig. 4) to hot water storage tank 6.

More specifically, composition thermal source hot water circulation loop that this utility model have employed solar energy (solar thermal collector 1) and the coupling of two closed circuits of biomass energy (straw kitchen range chuck hot water apparatus 4) is incorporated into the power networks, and thermal source hot water circulation loop and diaphragm type pipe hot water circulation loop.Work process of the present utility model is as follows:

When outdoor solar light is abundant in the winter time, intensity of solar radiation is big, solar heat source system is opened, recirculated water enters solar thermal collector 1 and heats, circulating water temperature is detected by the exit attemperating unit 2 of solar thermal collector 1, when temperature is higher than 10 DEG C��15 DEG C, then valve K3 opens, and valve K2, K1, K4 close, there is provided energy to hot water storage tank 6, pressurizeed by water circulating pump 3 after heat exchange, be again back to solar thermal collector 1 and heat. At night or sunlight is inadequate, temperature lower than 10 DEG C��15 DEG C time, start straw kitchen range chuck hot-water heating system, valve K1, K4 open, valve K3, K2 close. Need to illustrating a bit, this pattern is being run initially, need to heat by auxiliary electricity consumption thermal-collecting tube 8, until methane outlet 13 has biogas to cut off auxiliary electricity consumption thermal-collecting tube 8 power supply after flowing out.

Intensity of the sunlight is not enough, rely solely on solar thermal collector 1 can not circulating water heating to design temperature time, adopt the scheme of the grid-connected driving methane-generating pit for farm household temperature-increasing system of low-grade energy such as solar energy, biomass energy (straw kitchen range chuck hot water apparatus 4), it is ensured that biogas stable supplying uses. Namely it is heated to uniform temperature by 1 water of solar thermal collector, then enter back into straw kitchen range chuck hot water apparatus 4 to carry out auxiliary heating, reach set temperature, to guarantee that biogas stable supplying (combines coupling feature for straw kitchen range chuck hot water apparatus 4 with solar thermal collector 1, consider that driving heat source is incorporated into the power networks reality, association system coupling need to be built and run control model, it is easy to the overall coordination debugging solving between internal system links, operating structure between each link in optimization system, improves the Stability and dependability of association system performance).
