Description
Technical field
The present invention relates to biogas generating device, be specifically related to a kind of methane-generating pit utilizing solar energy heating.
Background technology
It is known that, biogas is the green energy resource that a kind of energy-saving and environmental protection are economic again, favored widely, produce biogas and can process house refuse, energy-conservation environmental protection again, biogas residue and biogas slurry again can be as green fertilizer for farmland fertilizations, it is possible to reduce the usage amount of chemical fertilizer, can produce green organic vegetable and grain.But owing to the generation of biogas has the high requirement of comparison to temperature, it is not the most fine that the biogas of the northern area of China is promoted, because northern area only could meet the Production conditions of biogas in summer when temperature is the highest, the biogas that all cannot produce q.s under time period that spring and fall temperature is relatively low and the normal temperature condition in winter is used, the methane-generating pit being built in underground the season of cold weather also easily causes damage because of freeze injury, has had a strong impact on the development of north methane industry.Although someone expects making the temperature of methane-generating pit raise to meet the occurrence condition of biogas by the way of heating, but owing to utilizing usual manner heating methane tank observable index higher, does not has economic benefit to say always, these mode of heatings cannot be promoted at all.
Summary of the invention
It is an object of the invention to not reach the requirement producing biogas for the northern area of China temperature, currently used methane-generating pit mode of heating energy consumption is high, does not has economic benefit to say, it is impossible to the defect being promoted, it is provided that a kind of solar energy heating formula methane-generating pit.
nullThe technical solution of the present invention is: it includes methane tank body，It also includes heating apparatus for biogas generating pit，Heating apparatus for biogas generating pit includes base、Water tank、Several Fresnel Lenses、Heating pipe and water pump，Each Fresnel Lenses and water tank are separated at intervals certain distance and are separately mounted on lens carrier，Lens carrier can be with pitch regulation angle to guarantee that each Fresnel Lenses focuses in water tank along horizontally hinged being axially hinged on water tank，Water tank is the channel-shaped body of upward opening，The focal position heat accumulation body the most one to one of several and each Fresnel Lenses is installed in water tank，Water tank is rotatably installed on base and can horizontally rotate，The bull gear installed on water tank is meshed with the little gear on the reducing motor output shaft being arranged on base，Reducing motor is rotated by little gear driven water tank and each Fresnel Lenses and realizes following the tracks of sunlight，Heating pipe is coiled in the sidewall of methane tank body and the outside of diapire，One end of heating pipe is connected with the outlet of water tank by water pump、The other end is connected with the water return outlet of water tank.
The solution have the advantages that: it uses sunlight as light source, utilizes Fresnel Lenses sunlight focusing to add hot water and methane-generating pit is circulated heating, have Energy input little, and biogas obtains many advantages, has significant economic benefit.Solar light focusing can be changed into heat energy by Fresnel Lenses efficiently, and can be always ensured that each lens face the projecting direction of sunlight always along with the movement of sunlight, to reach efficiently to utilize the purpose of solar energy.This methane-generating pit mode of heating has only to arrange a reducing motor with water tank and lens along with sunlight rotates, and reducing motor and water pump all use intermittent work mode, reach to save the purpose of electric energy.Methane-generating pit automatically can be heated by it in the season that temperature is not high enough, to reach the purpose of northern area whole year production biogas, and energy-conservation environmental protection again, it is worth promotion and application widely.
