Background technology
The optimum temps that shows the methane-generating pit mesophilic digestion according to pertinent data is about 35 ℃, usually adopt nearly mesophilic digestion 25-30 ℃ in the engineering, traditional methane-generating pit is emphasized versatility, and consider less to user's practical situation, most natural temperature aerogenesis that rely on, ignored winter low temperature to the influence of methane-generating pit, thereby caused methane-generating pit winter factor of created gase low, the biogas that produces can not be used for heating, cause the popularization stagnation of present biogas technology, meanwhile, the device of some high insulating effect has produced certain effect, but because complex structural designs, many reasons such as cost of use height cause actual applying seldom.
Summary of the invention
Low or temperature can not influence the problem that biogas technology is promoted by normal gas producing unstable winter of causing owing to temperature at methane-generating pit in the prior art, the invention provides a kind of simple in structure, reasonable in design, save energy effectively utilize boiler afterheat in inside, pond the device to the methane-generating pit heating.
Above-mentioned purpose of the present utility model is achieved in that accompanying drawings is as follows:
The family is made up of waste heat circulation and hot water circulation two portions with heating methane-generating pit heating unit, the waste heat circulation is for being arranged at the flue gas heat exchange device 8 of methane-generating pit 12 inwalls, the inlet mouth of flue gas heat exchange device 8 is connected with the smoke discharging pipe of hot water boiler 13, smoke discharging pipe 13 is provided with blower fan 5, and the air outlet of flue gas heat exchange device 8 and cigarette fontanel 10 communicate; Hot water circulation is the hot water heat exchanger 9 that is arranged at the methane-generating pit bottom, and the water inlet pipe 2 of hot water heat exchanger 9 links to each other with the water outlet of boiler 1, and its rising pipe 14 links to each other with the water inlet pipe 3 of boiler 1 by extra-feed tank 6, water pump 4.
Be provided with thermoscope 11 in the described methane-generating pit.
The beneficial effects of the utility model are as follows:
The utility model adopts hot water circulation heating system and bootstrap system acting in conjunction, guarantees methane-generating pit fermentation in warm temperature range 25-35 ℃ near, ferments fast, and gas production rate is big, the raw material availability height.Biomass pool structure is simple, reasonable in design, with low cost, be specially adapted to China's northeast extremely frigid zones.
Description of drawings
The utility model is described in further detail below in conjunction with the accompanying drawing illustrated embodiment:
Fig. 1 is family heating methane-generating pit heating unit structure iron.
Among the figure: 1-boiler 2-hot water heat exchanger water inlet pipe 3-boiler water inlet pipe 4-water pump 5-blower fan 6-extra-feed tank 7-opening for feed 8-flue gas heat exchange device 9-hot water heat exchanger 10-chimney 11-thermoscope 12-methane-generating pit 13-smoke discharging pipe 14-rising pipe 15-valve
Embodiment
The utility model is to adopt boiler afterheat and hot water circulation two jacket heating systems to guarantee the stability of methane-generating pit temperature, wherein in the boiler afterheat heating system, hot water boiler 1 is connected with smoke discharging pipe 13, smoke discharging pipe 13 is connected with flue gas heat exchange device 8 in the methane-generating pit, the outlet of flue gas heat exchange device 8 is connected with chimney 10, and valve 15 and blower fan 5 are housed on the smoke discharging pipe 13.The high-temperature flue gas that boiler 1 is discharged enters flue gas heat exchange device 8 on methane-generating pit 12 inwalls through boiler exhaust gas pipeline 13, and discharges by chimney 10 after natural pond liquid and the natural pond slag heat exchange.
In the hot water circulation, extra-feed tank 6 is connected with boiler water inlet pipe 3, water pump 4 and valve 15 are installed on the boiler water inlet pipe 3, boiler 1 is connected with the water inlet pipe 2 of hot water heat exchanger, water inlet pipe 2 is connected with hot water heat exchanger 9, hot water heat exchanger 9 is connected with rising pipe 14, and rising pipe 14 is connected with extra-feed tank 6, constitutes water cycle.Water heats after water inlet pipe 2 enters hot water heat exchanger 9 and natural pond liquid and natural pond slag heat exchange through boiler 1.
7 is the methane-generating pit opening for feed, and thermoscope 11 is arranged in the pond.When methane-generating pit water-cycle heating and the acting in conjunction of flue gas heating system make after temperature reaches preset temp (35 ℃ of mesophilic digestion optimum tempss) in the methane-generating pit 12, water cycle stops to be methane-generating pit 12 heating, but boiler also will be indoor heating, still in operation, the flue gas heating system then will continue operation.When temperature is lower than 25 ℃ of design temperature scopes, restart water cycle and give methane-generating pit 12 heating with the flue gas heating system, make methane-generating pit 12 temperature go back up to 35 ℃ of optimum tempss once more.
