By adopting tank bottom heating and electric heating, the utility model has the advantages of, high heating efficiency, cleanness, and environmental protection and can be extensively applied to northern severe cold areas.
Description
Technical field
The utility model relates to a kind of methane-generating pit of heating, the methane-generating pit of heating at the bottom of particularly a kind of pond.
Background technology
Along with progressively going deep into of energy-conserving and environment-protective consciousness, in recent years, biogas comprehensive utilization obtains paying attention to and development gradually, and biogas, is built aspect, ecological rural area and brought into play more and more important effect improving resource utilization as novel rural area clean fuel.Yet the application of biogas mainly is distributed in southern area now, northern area is because temperature is lower, particularly winter low temperature temperature is unfavorable for that the microbial fermentation in the methane-generating pit produces biogas, causes methane-generating pit to reach normal air feed of several months, has limited the development of biogas comprehensive utilization.Therefore, the problem of heating of methane-generating pit has become one of important factor of restriction northern area biogas development.Publication number is the Chinese patent of CN2712921, a kind of heating type methane-generating pit is disclosed, the methane-generating pit outer wall is provided with radially identical ring-type combustion pond, its bottom is positioned on the same horizontal plane with the methane-generating pit bottom, the methane-generating pit both sides are respectively equipped with methane-generating pit and are centered close to opening for feed and discharge port on the same straight line, and combustion both sides, pond are provided with flue and opening for feed.The utility model has improved temperature in the methane-generating pit pond, makes winter methane-generating pit pond Wen Keda more than 20 ℃.But there are shortcomings such as heating is uneven, burning straw pollutes in this methane-generating pit.
Summary of the invention
The utility model provides a kind of methane-generating pit that can heat at the deficiencies in the prior art at the bottom of the pond.
The methane-generating pit of heating at the bottom of the pond, comprise methane-generating pit, opening for feed, discharge port and biogas air outlet, opening for feed and discharge port are arranged at the both sides of methane-generating pit, the biogas air outlet is arranged at the top of methane-generating pit, it is characterized in that, the methane-generating pit bottom is provided with heating coil, be provided with electric heating tube in the heating coil, electric heating tube links to each other with the heating unit that is arranged at the heating coil end, and the other end of heating coil is connected with temperature regulator, is filled with heat-conducting medium between electric heating tube and the heating coil.
The top of heating coil is provided with cement layer.This cement layer can effectively stop the corrosion of natural pond liquid, and does not influence heat radiation, makes heating coil more even to the heating of natural pond liquid.
Heating coil is served as reasons the transverse tube that is arranged in parallel and bend pipe that transverse tube is connected is from beginning to end formed.
The sidewall of methane-generating pit is provided with thermal insulation layer.
The utility model utilizes heating tube the heat transferred heating coil also finally to be passed to the natural pond liquid on top by heat-conducting medium by the cement layer of laying on the heating coil, to natural pond liquid heating mode gentleness, and can regulate temperature by temperature regulator, make the natural pond liquid in the methane-generating pit be in the suitableeest aerogenesis temperature all the time.
The utility model heats at the bottom of adopting the pond, and the heating efficiency height adopts electrically heated, and clean environment firendly can be widely used in northern frore area.
