A kind of biogas anaerobic fermentation device that utilizes sun power and ground heat integration to heat
Technical field
The utility model relates to a kind of sun power and ground heat integration heating device of utilizing, and particularly relates to a kind of big-and-middle-sized biogas anaerobic fermentation device that utilizes sun power and ground heat integration to heat.
Background technology
Produce in the process of biogas at the organism anaerobically fermenting,, need heat, conventional utility boiler heat supply at present or utilize the generator waste heat to heat for keeping certain leavening temperature.Because the anaerobically fermenting operation energy consumption is higher, therefore seek cheap heating device is the focus that anaerobically fermenting heats research and development always.The thermal source that nature such as sun power, underground heat is the most cheap, play an important role to improving the biogas fermentation temperature, there is the people on methane-generating pit, to build sun power temperature canopy at present to heat, or directly on the methane-generating pit gas hood, apply black heat absorption material, or vexed solarization pond is set utilizes sun power to give to enter the anaerobic jar material and heat preheating.But collecting efficiency is not high, and since do not have standby heat source as solar-heating replenishing when not enough, influenced greatly by day and night temperature, generally invest higher.
Summary of the invention
The purpose of this utility model provides the device that utilizes sun power and ground heat integration to heat in a kind of biogas anaerobic fermentation, and it utilizes solar water heater and Heat exchanging water pot combined heat, can reduce big-and-middle-sized biogas engineering and heat expense.
A kind of biogas anaerobic fermentation device that utilizes sun power and ground heat integration to heat, Heat exchanging water pot, anaerobic jar, heating coil and equalizing tank are arranged, it is characterized in that having a solar water heater of making by solar energy vacuum tube or solar heat-collection plate, the outlet of it and Heat exchanging water pot is respectively by pipeline, valve and the connection of two transferpumps inlets, carry pump outlet to connect for these two, and connect with the inlet of two transferpumps respectively by pipeline, valve, Y-tube by the inlet of pipeline, valve, Y-tube and heat storage can; Two carry pump outlet through pipeline, valve, Y-tube respectively with anaerobic jar and equalizing tank in the inlet of 2-30 parallel heating coil coiling connect; The outlet of two heating coils is connected through the outlet of pipeline, Y-tube, valve and heat storage can, and be communicated with the inlet of solar water heater and the inlet of Heat exchanging water pot through pipeline, Y-tube, valve, transferpump, also be communicated with simultaneously, connect with the pipeline that electrically-controlled valve is housed between the water inlet main pipe line of above-mentioned two heating coils and the water outlet main pipe line with the outlet of water softener tank; On water inlet main pipe line and the water outlet main pipe line thermometer is installed respectively.
The utility model has the advantages that and adopt collecting efficiency valve tube or thermal-arrest plate high and that have a heat insulation function to adopt heat, replenishing when standby heat source is arranged as the solar-heating deficiency, can be anaerobically fermenting stable thermal source is provided, heat accumulation tank regulating pondage balance is arranged, heat balance, heat accumulation when can be evening or break down maintenance has thermometer in order to instruct the unlatching of transferpump or standby heat source.

Embodiment
The utility model has Heat exchanging water pot 2, anaerobic jar 8 and heating coil 9,11 and equalizing tank 10, it is characterized in that having a solar water heater 1 of making by solar energy vacuum tube or solar heat-collection plate, the outlet of it and Heat exchanging water pot 2 is respectively by the inlet connection with transferpump 3, transferpump 4 of pipeline, valve, the outlet of this transferpump 3 and transferpump 4 is connected by the inlet 18 of pipeline, valve, Y-tube and heat storage can 5, and connects with the inlet of transferpump 6, transferpump 7 respectively by pipeline, valve, Y-tube; The inlet of the outlet of transferpump 6 2-30 parallel heating coil 9 of coiling in pipeline, valve, Y-tube and anaerobic jar 8 is connected; The inlet of the outlet of transferpump 7 2-30 parallel heating coil 11 of coiling in pipeline, Y-tube, valve and equalizing tank 10 is connected; Heating coil 9 is connected through the outlet 19 of pipeline, Y-tube, valve and heat storage can 5 with the outlet of heating coil 11, and be communicated with the inlet of solar water heater 1 and Heat exchanging water pot 2 respectively through pipeline, Y-tube, valve, transferpump 12, also be communicated with simultaneously, connect with the pipeline that electrically-controlled valve 15 is housed between the water inlet main pipe line 13 of above-mentioned heating coil 9 and heating coil 11 and the water outlet main pipe line 14 with the outlet of water softener tank 22; On water inlet main pipe line 13 and the water outlet main pipe line 14 thermometer 16 is installed respectively.
The tank body of described heat storage can 5 is a round shape or cube shaped, and heat storage can 5 outer covering and heat insulating layers 17 have arcual baffle plate 20 near import 18 and outlet 19 places in the heat storage can 5, open 2-10 hole along the outer wall vertical of heat storage can 5 and are connected with thermometer 21 respectively.
When using the utility model, the inlet of water softener tank 22 and the outlet of extraneous water supply installation are connected, water is after water softener tank 22 softening processing, by transferpump 12 respectively through pipeline, valve enters solar water heater 1 and Heat exchanging water pot 2 internal heating, through solar water heater 1 heated hot water through piping, valve, Y-tube is transported to the heating coil 9 of coiling in the anaerobic jar 8 respectively by transferpump 3 and transferpump 4, circulate in the heating coil 11 of coiling in the equalizing tank 10, simultaneously portion water 18 is transported to heat storage can 5 through entering the mouth, hot water is through baffle plate 20 homodisperse, in heat storage can 5, form slice gradient by temperature, thermometer 21 on heat storage can 5 tank skins shows jar an interior temperature and a thermograde, the outlet jointing temp meter 16 of heating coil 9 and heating coil 11, hot water becomes water coolant and is sent back in the solar water heater 1 after the heat exchange circulation.Heat storage can 5 provides hot water to heating coil 9 and 11 internal recycle as thermal source when night and break down maintenance, and Heat exchanging water pot 2 is as the standby heat source at winter or cloudy day.
